Small Steps, Giant Leaps: An Alternate History of the Space Age

Teaser
  • Before we kick things off, a quick teaser...

    So, I had an idea last year for a timeline centered around the Apollo Program - basically, what reasonable changes could've happened so that more landings occurred. Nothing too complicated. What started out as a small timeline, however, quickly became much more than that, with plenty of prodding from @KAL_9000 - I'd originally planned to end it some time in the '70s with the end of Apollo. Try adding about 5 extra decades on, and you've got the monstrosity of a spaceflight timeline-to-be that is:

    Part 1: 'Go Fever' Breaks
  • Small Steps, Giant Leaps - Part 1: 'Go Fever' Breaks​


    December 29th, 1966

    Problems, problems, problems. Project Apollo hadn't even flown a single man in space yet, but already it was running up against some pretty serious roadblocks. With hardly 3 years left to accomplish the late president Kennedy's goal, many within the halls of the National Aeronautics and Space Administration had begun to wonder whether it was truly possible.

    The Apollo Block I Command Module for the first manned test flight, Command Module-012, had arrived at Cape Kennedy in late August, bringing with it hundreds of engineering changes needed before it was flight-ready.[1] With those completed, the capsule was mated to a Service Module inside of Kennedy Space Center's altitude chamber for combined testing of the spacecraft's systems, both uncrewed and crewed. This testing revealed even more problems - a leaky Environmental Control Unit in the Command Module had to be removed and fixed twice before actually working, and the Service Module had to be separated from the CM and removed from the chamber for inspection after a tank in another SM had ruptured during testing at North American.[2]

    Finally, though, by late December, all these problems had been fixed, and the spacecraft had been reassembled and put back in the altitude chamber. The final crewed test in the chamber, performed by the backup crew of Walter Schirra, Donn Eisele, and R. Walter Cunningham, was set to take place the next day, December 30th. Before that, however, one last uncrewed test to verify the capsule - a "dry run" before the backup crew came in tomorrow.

    It was getting on in the evening - just after 6:00 - as the test finally got underway, following the craft's reassembly and re-installation. This would be a repeat of earlier testing, nothing too complex; just slowly reduce the pressure in the chamber to near-vacuum conditions, verify all systems were working properly, re-pressurize the chamber, and call it a night. At least, that was the plan.

    The first, unnoticed sign of trouble came around 6:20. For a moment, barely a second, the instruments monitoring the spacecraft's power systems indicated an increase in AC Bus 2 voltage before returning to normal. This went unnoticed by the technicians monitoring the spacecraft systems at the time - it was hardly a blip in the radar, only found after the fact in data analysis. The altitude chamber was only about one-third of the way depressurized at this point; nobody wanted to accidentally damage the spacecraft systems by rushing the test, and add unnecessary extra days of repair, refit, and re-testing, especially after the headache that the last few months had been.

    The next sign of trouble, this one very plainly noticed by the technicians, came about 20 seconds later, as the internal cabin pressure suddenly began to rise exponentially, accompanied by a similar spike in temperature. The technician watching these indicators sighed as the needles shot upwards, exasperated by what seemed to be yet another problem that'd need fixing. "I've either got an equipment failure or some kinda gas leak here, fellas. Pressure and temperature are going wild."

    Suddenly, there was a muffled bang - it could've easily been mistaken for someone in another room dropping something heavy, had it not been accompanied by a bright orange glow, now visible through a small, round porthole window in the altitude chamber. At this point, it was abundantly clear what had gone wrong.

    "We've got a fire!"
    "Jesus, get a team in there!"

    The room fell into chaos for a moment as the technicians scrambled to re-pressurize the chamber, grab fire extinguishers and emergency gas masks, and pull the fire alarm. One technician rushed up to the chamber window to see the extent of the fire, and glimpsed what he would later describe as "... a jet of flame, erupting from the side of the capsule like a flamethrower."[3]

    It took approximately 15 seconds for the chamber to quickly re-pressurize, after which the door could be opened and the blaze could be extinguished. From there, it took another four frantic minutes for the capsule's complex double-hatch to be disassembled and opened. By this time, however, it was far too late - the Command Module was all but destroyed, the interior surfaces caked in soot and the charred remains of various equipment; and sporting a large, charred hole and a trail of soot obscuring the flag and the black "UNITED STATES" painted onto the capsule's grey exterior.



    In line with NASA policy written in the aftermath of Gemini 8's dangerous in-flight failure earlier that year, a review board was put together to assess the cause of the fire. This board included, among others, all three members of the crew planned to fly on this mission - Command Pilot Virgil I. "Gus" Grissom, Senior Pilot Edward H. White, and Pilot Roger B. Chaffee - along with spacecraft designer Maxime Faget, and Langley Research Center director Floyd L. Thompson chairing the board.

    The Apollo 204 Review Board's final report, issued in April of 1967 after extensive disassembly and inspection of the spacecraft and other Block I spacecraft like it, concluded that the cause of the fire was a combination of damaged wiring, a leaking coolant line, an excess of flammable materials in the capsule, and the pure oxygen atmosphere which the capsule was pressurized with. The report also concluded that the Block I Apollo Command Module was unfit for spaceflight, and that more changes would need to be implemented for the Block II spacecraft to be considered safe for crewed flight, including a quick-opening hatch, a new cabin atmosphere at launch, and the addition of new insulation on various plumbing and wiring.[4] Revelations about the crew's concerns with the spacecraft, raised with (and dismissed by) Apollo Spacecraft Program Office Manager Joseph Francis Shea in the months preceding the fire, led to Shea's reassignment (and eventual resignation from NASA entirely) and replacement with George Low in April of 1967. Gus Grissom is alleged to have nearly gotten himself fired after a contentious phone call with Shea in the days following the fire, allegedly telling him "We need a man on the Moon before 1970, but a dead man on the Moon won't accomplish a damn thing."[5]



    The failure of AS-204/Apollo 1 to get anywhere close to flying was seen initially as another major setback in the timeline for the Apollo Program. In its aftermath, however, a new sense of determination seemed to emerge. It took over a year for the recommended changes to be implemented for the Block II CSM, during which time three uncrewed test flights took place - Apollo 4, the first launch of the mighty Saturn V rocket that would propel man to the Moon; Apollo 5, an uncrewed test flight of a Lunar Module in Earth orbit; and Apollo 6, a second uncrewed Saturn V flight.[6]

    By the autumn of 1968, Project Apollo was ready, finally, to fly its first crew. With the nearly two-year delay between AS-204's unfortunate end and this new planned mission, Grissom, White, and Chaffee had plenty of time to learn the ins-and-outs of the newer, more complex Block II spacecraft, and so the crew were selected to fly this first mission in place of their original planned flight. [7]

    Apollo 7, as the mission was designated under the new numbering system, would be an extensive check-out of the Apollo Command and Service Module in low Earth orbit over the course of ten days in orbit. To help in distinguishing between the crew, in line with new NASA policy, Grissom, White, and Chaffee's official "positions" on the mission changed - Grissom went from "Command Pilot" to simply "Commander", White became "Command Module Pilot", and Chaffee was named "Lunar Module Pilot", despite the lack of a Lunar Module on Apollo 7's flight.[8] At the recommendation of backup Commander Walter Schirra, Grissom elected to name the Apollo 7 spacecraft "Phoenix", in reference to the fire which Project Apollo had overcome. This tradition of naming spacecraft carried over from Project Mercury, and was a reversal of an earlier NASA management decision (after Grissom nicknamed his Gemini 3 capsule "Molly Brown", in reference to a Broadway musical) to disallow astronauts from naming their capsules; this reversal was in part because future Apollo flights would have two separate spacecraft, which would necessitate different callsigns for each to avoid confusion.[9]

    Apollo 7 launched successfully on Saturday, October 12th, 1968 from Launch Complex 34, after a launch scrub the previous day due to unfavorable wind conditions.[10] The Saturn IB rocket carried Grissom, White, and Chaffee to orbit aboard their spacecraft, Phoenix, which spent the next 10-and-a-half days in orbit, during which the crew rendezvoused with their spent S-IVB upper stage, tested the spacecraft's Service Propulsion System, and conducted the first live television broadcast from an American spacecraft. Despite a schedule that Grissom would describe in the post-mission debrief as "more than a bit overfull", Apollo 7 accomplished all of its major mission objectives, and proved that the Apollo Program was well on track to its goal of landing a man on the Moon before the end of the decade.



    Thank you for reading! The notes are as follows:
    [1] and [2]: this is, as it's before the POD, exact to our timeline. As per Wikipedia, 113 incomplete changes from North American were completed after arrival, and 623 new engineering changes were requested and made at KSC. Yikes.
    [3]: as a note here during this scene, I haven't the foggiest idea what altitude chamber testing would actually look like at NASA circa 1966, nor do I know the names of any technicians who'd be doing that testing. I fully welcome any and all input there.
    [4]: the changes to the Apollo CSM in the aftermath of the fire can be assumed to be the same/similar enough to IOTL that it's not worth going into the details. The Apollo spacesuits are likely changed as well to be less flammable - again, the same as IOTL.
    [5]: This quote is all @KAL_9000 - KAL wrote up a post about how Grissom might react to his capsule exploding during an uncrewed test, given his previously expressed concerns about the spacecraft, back in November when this timeline was coming into being; at some point I may post that, as sort of a "beta" version and/or an alternate perspective.
    [6]: Apollos 4/5/6 can be assumed to be similar to/the same as IOTL - between Apollo 4 and Apollo 6, both missions revealed the issues with the Saturn V that were fixed before OTL Apollo 8 (pogo oscillations, ignition line damage, spacecraft adapter issues, etc.).
    [7]: since OTL's Apollo 7 crew was the backup crew for Apollo 1, I figured if the Apollo 1 crew lived, they'd have flown on 7. We'll see how this affects crew rotations down the road.
    [8]: Same as Apollo 7/8 IOTL, using "Block II" titles for the crew since they're flying on Block II.
    [9]: Schirra wanted to name the Apollo 7 capsule "Phoenix" IOTL, but NASA management rejected it - since the fire wasn't deadly ITTL, it's less of a black mark on NASA's record, and I figure Grissom could pull some strings as a well-loved Mercury astronaut and get his way.
    [10]: Apollo 7 launched on October 11th IOTL, despite unfavorable wind conditions. Schirra wanted to scrub the launch, but managers waived the rule. ITTL, Schirra and Grissom's concerns are heard, and the two of them together is enough to convince NASA management to delay the launch.

    Interlude 1: Reflexes
  • As a little bonus, a couple vignettes I couldn't find the space to fit into Part 1 that get their own little post here. They're one little divergence, and one big divergence, respectively.

    Small Steps, Giant Leaps - Interlude 1: Reflexes​



    Edwards Air Force Base
    December 8th, 1967


    Two Air Force technicians leaned against the large open doorframe of a hangar, watching the horizon. Out above the desert, a Lockheed F-104 screamed through the clear blue California sky, coming in for a steep landing. Right as it flared back on final approach, however, the technicians watched with surprise as the jet's canopy exploded off, and in quick succession, its two pilots ejected. With no pilot to correct course as it barreled towards the runway, the plane slammed into the ground hard, its landing gear crumpling as it caught fire. The ejected pilots, thrown safely away from the fireball, fell to Earth far too quickly for their parachutes to deploy fully.

    The technicians jumped into action at this sight, one running off to the nearest phone to call for medical and fire services, while the other grabbed an emergency first aid kit and ran out into the desert to go find the pilots. Not much later, as Fire Protection crews arrived on the scene to begin dealing with the F-104's wreckage, the technician, first aid kit in hand, ran up to the first of the two pilots he could find - thankfully, he saw, still moving.

    "Holy shit, you alright?"

    The pilot lay on the ground, his grey flight suit and white helmet covered with sand and dust. He tried to sit up, wincing in pain as he moved, before thinking better of it, and simply reaching up to detach his mask from his helmet. "Well," he sad matter-of-factly to the technician who now knelt next to him, sifting through a first-aid kit, "I've definitely busted a couple ribs. Don't think I'm bleeding anywhere."

    The technician nodded, still a bit bewildered that the man on the ground before him was alive. "That was quite the lucky eject."

    "Yeah," the pilot agreed, flashing a small smile. "I was flying backseat. Royer flared too late - I pulled the eject, got us out."

    "Quite some, ah..." the technician paused, scanning the airman's flight suit for an indication of name and rank. Spotting it, he continued, "Quite some reflexes there, Major Lawrence."[1]



    Ambassador Hotel, Los Angeles
    June 5th, 1968, just after midnight


    The kitchen of the Ambassador Hotel was unusually packed for this hour of night. Most nights when the Ambassador hosted big events in its ballroom, everything wrapped up much earlier, and the staff could go about cleaning and getting home. Tonight, however, was different - Bobby Kennedy's campaign had the hotel absolutely packed with supporters and media, in pretty much every ballroom the Ambassador had to offer. It was a surprise, then, but not a huge one, when the maître d'hôtel led Kennedy through the kitchen, surrounded by a swarm of press, campaign aides, and two big bodyguards. The Senator, still flushed red after giving a speech and navigating the crowd, stopped throughout the kitchen a number of times to shake hands with the staff. On one such stop, Kennedy paused in a narrow hallway to shake the hand of 17-year-old Juan Romero. The young busboy was happy to congratulate the Senator - He'd brought Kennedy room service the day before and wished him luck, and it seems that luck had paid off; Kennedy had won the California primary.

    As Juan shook the Senator's hand, he caught some movement out of the corner of his eye, and reflexively glanced to his side - time working in a busy hotel kitchen had given him an awareness of his surroundings, months of avoiding coworkers carrying hot pans and trays full of plates.[2] What he saw this time, however, was a short, unfamiliar man, stepping from behind an ice machine and pulling out a gun as he moved to push past the maître d'hôtel. In a moment of panic, Romero attempted to jump out of the way, inadvertently tackling Senator Kennedy to the ground as he did so. Shots rang out - it was clear that this man, whoever he was, was attempting to kill the Senator and his entourage.

    The scene turned chaotic at once - the would-be assassin fired wildly as two of Kennedy's bodyguards and a reporter lunged forward to disarm him, shooting one of the bodyguards in the chest. Kennedy took a bullet in the arm as he went down. In the ensuing struggle, 6 people were wounded - Kennedy, his bodyguard, two reporters, a campaign volunteer, and Romero, who was shot in the lower back while shielding Senator Kennedy before the gunman was disarmed.

    As the scene was rushed by reporters and photographers, Kennedy looked to the young man who now sat on the floor beside him, leaning up against the wall and breathing heavily. Juan Romero looked back at the Senator, and asked, "Are you OK? Is everybody OK?" to which Kennedy responded, "Yes, everybody's OK."[3]



    And that concludes Interlude 1! You can probably see why I wanted to include these - a couple deaths not happening as they did IOTL can really change things, in small and big ways.

    notes:
    [1]: For those who don't immediately know who this guy is and who don't mind minor spoilers for things to come, here's his Wikipedia page.
    [2]: I worked in a large kitchen for a little less than a year, and this absolutely happens - you start to become aware of things in your periphery, especially when there's people walking around with hot pans and knives and such.
    [3]: This is a reversal of IOTL, where busboy Juan Romero cradled a dying Kennedy on the kitchen floor, and Kennedy asked him "Is everybody OK?" to which Romero responded "Yes, everybody's OK." I imagine Romero lives, though we probably won't touch back on him specifically - but expect to hear more from Bobby Kennedy.

    Part 2: De la Terre à la Lune
  • Small Steps, Giant Leaps - Part 2: De la Terre à la Lune​



    Sunday, August 11th, 1968

    Deke Slayton was not a happy man. At least, not at the moment.

    While the Apollo program had been chugging right along with unmanned test missions for the last year or so, all was not well. Apollo 4 had beaten all expectations last November when the mighty Saturn V had performed flawlessly on its first flight, and while Apollo 5's January test flight of the Lunar Module wasn't without issue, it'd been declared a success and another repeat test had been cancelled in favor of moving on to manned testing. Apollo 6 is where things really got concerning, however - the second unmanned test of the Saturn V, launched this past April, had experienced severe pogo oscillations during its ascent, damaging the spacecraft adapter, rupturing fuel lines and causing three engine failures - two on the S-II second stage mid-ascent, and one on the S-IVB upper stage when it tried to re-ignite for a simulated Trans-Lunar Injection. These issues would've resulted in an aborted mission, had they happened on a manned flight. This alone jeopardized the whole program, if the rocket it rested on continued to have such serious issues.

    Worse than all that, the LM continued to suffer from chronic production delays and issues. LM-3, intended for Jim McDivitt's test flight on Apollo 8, had arrived at KSC back in June, and, like many a spacecraft before it, was riddled with issues that'd take time to fix. Manned Spacecraft Center Director Bob Gilruth and his team had concluded that there was, as it'd been put to Deke in a phone call, "No way in hell" that LM-3 would be ready to fly before 1969. This jeopardized the next two flights - Apollo 8 and Apollo 9, intended to test the LM in Earth orbit - and pushed the timetable back so far that it'd be November of 1969, ideally, when the first man walked on the Moon. This was too thin of a margin to risk, given how many delays could happen in the 14 months of time between now and then.

    The solution to these problems, hopefully, had been proposed in a meeting two days ago by George Low, Manager of the Apollo Spacecraft Program Office. He'd figured that, hey, CSM-103 would be ready a few months before LM-3, so why not send a CSM-only mission to the Moon? This'd skip ahead in the timeline, and allow NASA to test some of the lunar landing procedures in December of 1968, rather than holding off until Apollo 10, which, assuming the previous timeline, wouldn't have been until maybe July of 1969. Bob Gilruth, George Low, Flight Director Chris Kraft, and Deke had all flown down to Huntsville this past weekend and spoken with the team there, and they'd all considered it feasible, pending approval from NASA Administrator James Webb some time in the next week. The next Saturn V could be ready by December 1, and both KSC Director Kurt Debus and Wernher von Braun assured the group that the issues experienced on Apollo 6's flight would not be repeated.



    Deke had called both Jim McDivitt and Frank Borman yesterday to let them know that their crews - Apollo 8 and Apollo 9, respectively - might be flying a lunar mission, and to schedule meetings with them today to discuss it more thoroughly in-person. He'd met with McDivitt first, since his crew was slated for Apollo 8. It'd been a short conversation, with Deke laying out the basics - CSM-only mission, flying to the Moon and back - and Jim, after a moment of thinking, laying out why he figured it'd be better for his crew to hold off, so they could fly a mission with a Lunar Module. While this'd been a disappointment, it was by no means the end of the world - there were still options.

    Now it was Borman's turn. He sat in a chair across from Deke, hands clasped together beneath his chin, as if in prayer, as he considered the offer that'd just been presented - he'd take Apollo 8, and fly around the Moon, while McDivitt and his crew would be swapped to Apollo 9 for the LM test.

    After a good 30 seconds of quiet contemplation, Frank spoke up.

    "Deke, I appreciate the offer, but I'm really not sure about it. My crew's been training for a mission with a LM, and I phoned both of them yesterday; Jim doesn't mind much, but Bill didn't like the sound of being a LM pilot on a mission with no LM, and I'm inclined to agree. If I turn this down, are we still square to fly a LM test? It'd be 10, wouldn't it, if this moon flight pushes it all back one."

    Deke sighed a bit, but nodded. "Yes, you'd be on 10 if you don't fly 8. It'd be a longer and more intensive mission, but you'd have a LM, and I trust your crew is fully capable of that mission. I've got other options for this one, if you're certain."

    Borman nodded curtly in response to this, and after a few more minutes of talk about mission logistics, he shook Deke's hand, thanked him, and left.

    While it was a bit of a stretch, Deke hadn't been lying - he did have one last option for a CSM-only mission to the Moon. After stepping out to grab himself another cup of coffee, he turned to head back to his office, to schedule a meeting with Apollo 7 backup commander Walter Schirra.



    December 21st, 1968 - Apollo 8 MET 2 hours, 27 minutes

    The Apollo CSM was damn roomy, at least by Wally Schirra's standards. His two companions on this voyage had no metric by which to judge, having never been to space before; but for Wally, this was absolute heaven. The Mercury capsule on his first, nine-hour spaceflight had been little more than a metal broom closet, and Gemini was hardly any better. Apollo, by comparison, felt like a five-star hotel, with room enough for three men to live in space for over a week.

    The training for this mission had been a whirlwind - he and his crew had been pulled off of 7's backup with only months to spare, and he'd lost his original CMP when Donn Eisele's affair was leaked to a Houston tabloid back in October, so he'd only had 2 months to train with his backup CMP originally from the Apollo 7 support crew, Jack Swigert. He'd settled in well enough, though, and Wally had gained a respect for Swigert's work ethic in the time they'd trained together.

    Launch day had proceeded as expected - President Johnson was in attendance at KSC to watch the launch of course, but the real star of the show had been President-Elect Kennedy; He'd joined the crew for breakfast (steak and eggs, as was tradition) early that morning before touring his brother's namesake Space Center while the crew suited up and prepared for a launch just before 8AM. He was a humble fellow, quieter and less charismatic than Jack Kennedy had been when Wally had briefly met him back in 1961, but with a gentle kindness to him. The launch itself had been, all at once, both spectacular, terrifying, awe-inspiring, and surprisingly smooth - both Atlas, which had launched Mercury, and Titan, which had launched Gemini, were converted from ICBMs never intended to carry humans, and rode rough because of it; the Saturn V, meanwhile, was intended from the start to launch man to the Moon, and was much smoother. The first Earth orbit after launch had so far consisted of checking out the spacecraft's systems, before heading onwards.

    Wally took a moment of quiet to contemplate all this, the adrenaline of launch still wearing off, before there was a crackle over the comm, and CAPCOM Neil Armstrong's deep baritone voice.

    "Jules Verne, Houston."

    "Go ahead, Houston." Schirra responded, resisting the urge to do so in a comically bad French accent - something he and the crew had picked up in training after choosing their ship's name, after the French author of a fictional voyage around the Moon.

    Armstrong's next words pushed that thought from his mind, however:

    "Jules Verne, you are go for TLI. Over."

    The capsule went quiet as the three astronauts listened; Schirra responded after a moment.

    "Roger, understood. Apollo 8 is go for TLI."

    At the call, Wally looked over to Jack, meeting his eyes with a grin. From below them, Walt Cunningham's head poked up from the lower equipment bay. Looking to his rookie crewmates, Schirra declared with a smile, "Gentlemen, we're going to the Moon."



    December 24th, 1968 - Apollo 8 MET 86 hours, 5 minutes

    "... and as we're coming over the Sea of Tranquility, you can start to see the long shadows from that stark lunar sunrise, those deep craters really standing out."

    Walt Cunningham held the TV camera facing the CSM window, looking out on the stark lunar horizon and narrating for the viewers back on Earth what was passing by. Out of earshot of the broadcast, Wally waved to grab Walt's attention, holding up his copy of the laminated mission procedures.

    "We're gonna read the thing and wrap up, Walt."

    Cunningham nodded, holding the camera steady with one hand and continuing his narration as he reached for his own laminated notebook floating nearby.

    "Alright folks, we're now approaching the lunar sunrise over Tranquility, and we'd like to close with something special for all the children watching and listening back on planet Earth."

    He paused, looking down to his script, before continuing:

    "'Twas the night before Christmas, when all through the house
    Not a creature was stirring, not even a mouse;
    The stockings were hung by the chimney with care,
    In hopes that St. Nicholas soon would be there."

    At this, Jack piped in, reading from his own book:

    "The children were nestled all snug in their beds;
    While visions of sugar-plums danced in their heads..."

    And so the three crewmen traded off, each reading lines from the poem, with the Commander closing the broadcast with the final lines:

    "... But I heard him exclaim, as he drove out of sight—
    'Merry Christmas to all, and to all a good night!' --
    And from the crew of the good ship Jules Verne, on Apollo 8, we close with good night, a very Merry Christmas, and peace for all of you on the good planet Earth."

    Thank you once again for reading! Things are starting to get exciting - RFK's won the election, and the Apollo program's crew selections have started to diverge from OTL in a way that'll ripple through the whole program. Feel free to ask any questions, and KAL and I will try our best to answer anything that isn't a spoiler. Next time, we'll take a look at Apollo 9 and possibly 10, and maybe even find out who the crew will be for the first landing...

    notes for this time (no in-text notations this time to fit the more narrative style):
    - The 1968 election was RFK v. Nixon v. Wallace, and RFK beat out Nixon by a pretty decent margin - I'll probably post the map and some details as an appendix at some point if y'all want.
    - The issues with Apollo 5 and 6 are the same as OTL.
    - Deke Slayton really did offer McDivitt the circumlunar mission, and he really did turn him down in favor of swapping to Apollo 9.
    - IOTL as ITTL, Bill Anders really didn't want to be a Lunar Module Pilot on a mission with no LM.
    - Donn Eisele's affair didn't go public IOTL until after he flew on Apollo 7, but given the months of delay ITTL I figure he'd have more time to accidentally slip up.
    - The whole idea of giving the Apollo 7/8 CSMs names came from @KAL_9000 as did the name Jules Verne for the 8 CSM.
    - The famous poem they read at the end of the broadcast, Clement Clarke Moore's A Visit from St. Nicholas, can be read in full here.

    Interlude 2: Back in the USSR
  • It's time for the first KALterlude! Today, we'll be crossing the Iron Curtain and taking a look at the fallout of the Apollo 1 Incident for the Soviet program.

    Small Steps, Giant Leaps - Interlude 2: Back in the USSR



    The aftermath of Apollo 1's near-disaster had consequences on the other side of the Iron Curtain, of course, though they were not initially visible to anyone outside of the upper echelons of Soviet leadership and the Soviet space program. Although the Apollo 1 fire was initially dismissed as yet another failure of the capitalist West, the disastrous failure of Soyuz 1 and the tragic death of cosmonaut Vladimir Komarov raised comparisons from the Politburo, rather unfavorable ones, with the non-lethal failure of the American spacecraft.
    In response, in addition to the full-scale investigation and redesign of the Soyuz spacecraft, a more safety-conscious attitude would emerge among the space program going forward. The failure of Kosmos 154, although not caused by Proton's hypergolic propellants, prompted further concern over the use of such fuels on large rocket stages, undoubtedly spurred on by memory of the 1960 Nedelin Catastrophe. Ultimately, Vladimir Chelomei, the de facto head of the Soviet space program after Chief Designer Sergei Korolev's 1966 death, was demoted in early 1968, now in charge of solely the Proton and Soyuz programs.
    Vasily Mishin was chosen as the new N1-L3 program head, and he took a much more active interest in developing the rocket than his predecessor (although the oft-quoted story of Mishin falling asleep at his desk after working on a design issue for three days without rest is most likely apocryphal): Chelomei had disdained the N1 due to it being the brainchild of his rival Korolev. Chelomei's Soyuz and Proton programs, at least, saw success with Zond 5, the first mission to send living creatures around the Moon, and also a major stressor for NASA as they built up towards the first Apollo landing.

    Part 3: Decisions & Dramamine
  • Small Steps, Giant Leaps - Part 3: Decisions & Dramamine​


    December 23rd, 1968
    Manned Spacecraft Center, Houston, TX


    Gus Grissom would never admit it, but he was always a bit nervous whenever he entered Deke Slayton's office - always felt a little bit like being a schoolboy called to the head teacher's office, like somehow you'd done something wrong. Usually, a meeting with Deke meant one of two things: you were on a mission, or you were kicked off one. Today, however, he had a sneaking suspicion as to what this was about, and that helped quell some his worries as he took a seat.

    "Good to see ya, Gus."

    Gus nodded in response. "And you, Deke. What's the topic of the day, why'd you want to see me?" Gus had a few ideas, but Deke's answer narrowed it right down.

    "It's about 11, Gus. It's official: you're the commander if you want it, and so far... it looks like it may be the G mission."

    The astronaut couldn't help but crack a grin. "The moon, Deke? You'd better believe I want that. Who am I flying with?"

    "Dealer's choice. I've got a couple recommendations, but it's your command, and I want you working with a team you can trust."

    Gus leaned back in his chair - he'd subconsciously begun leaning forward. "I can think of a few, but fire away."

    "Alright, well, Mike Collins is off of Borman's because of that spine surgery, and Jim Lovell's in for him - they'll probably be up in May, but it's not too late to pull Lovell if you want him as your CMP."

    After a moment of pause, Gus responded, "I think Lovell ought to go up earlier than 11, put him in line for his own command. Mike Collins will do just fine. Works well with my pick for LMP- I want John Young, if that's alright."

    Deke nodded. "I can make that happen. Looks like we're putting together a Gemini 3 and 10 reunion tour." This got a laugh out of Gus.

    Indicating to the wall, Deke continued, "I'll go ahead and draw up the papers, you can use my phone to call John if you want. Mike's down in the trenches on CAPCOM for 8."

    Gus shifted his seat back, moving to stand up. "I appreciate it. Let me go ahead and give John a call, then I'll see if I can't grab a word over lunch with Mike once he swaps out."

    Picking up the phone, Gus had a brief conversation with Deke's secretary - John was out at North American's facility at Downey, so they'd have to have someone out there find him - and waited.

    ----
    North American Aviation Plant, Downey, CA

    John Young had hardly been here a half-hour, but he already felt a bit worn thin. He'd spent the morning since flying here poking around North American's sprawling facility, sticking his nose in half-completed spacecraft and glancing at paperwork at the behest of dozens of engineers wanting to get "an astronaut's view" on this, that, and everything. Mercifully, he'd just been pulled away to a phone - someone calling from Houston, hopefully with some more exciting news.

    Sure enough, he found himself on the line with Gus Grissom, who wasted no time in getting to the point. "John, Deke's just given me command of the G mission on 11. I want you flying the LM with me."

    John was grinning ear-to-ear as he responded. "Count me in, Commander. Who's our pilot?"

    "Mike Collins. Figured you two'd work well together a second time."

    "Fan- tastic. Looking forward to a little lunar vacation next year. I'll pack some sunscreen."

    On the other end of the line, Gus chuckled. "Gonna be a hell of a ride, John. Hell of a ride."



    March 3, 1969 - Apollo 9 MET 73 hours, 28 minutes

    Callsign (unofficial): Red Rover

    "Oh, there's Baja California. Oh, very pretty! Let's see if I've got some more film left here, snap some pictures..."

    Russell Louis "Rusty" Schweickart gazed down- or possibly up- at the entire Earth, watching the serene greens and blues and whites pass by below- or above- the CSM. He stood affixed to the Lunar Module Spider's porch by his booted feet in a pair of 'golden slippers', a tether trailing back into the open hatch. It was a surprisingly comfortable experience, all things considered - and that was sort of the point, testing the Portable Life Support System that future astronauts would wear while walking on the Moon.

    Schweickart EVA.jpg

    [Rusty Schweickart standing on the porch of the LM Spider, photographed by CMP Dave Scott]

    It'd been a bit of a ride to get here: Commander Jim McDivitt's health had almost caused the flight to be delayed a few days by the doctors, something about white blood cell count; thankfully, he rebounded the day before launch, and didn't develop a cold as they'd feared. Then, once they'd launched and settled in on-orbit, Rusty had found that, for some reason, his body just plain did not like being in space. It wasn't exactly a secret among the astronaut corps that sometimes things got a little funny up here - hell, rumor had it Walt Cunningham had the runs halfway to the Moon on Apollo 8 - so it wasn't exactly too big of a surprise when Rusty pretty immediately lost his lunch once he'd started moving around the spacecraft in zero-G. His saving grace had come in pill form - Dramamine anti-nausea medication; God knows where he'd be at without it, after 3 days in space.

    Through the gentle purr of the PLSS' cooling system, a crackle of static, and Jim McDivitt's voice: "Okay, Rusty, Dave's got his camera sorted out. Why don't you pass your camera back in here and work on the handrails, see if we can't get Red Rover on over into Gumdrop."

    Sure enough, Rusty passed his camera back to Jim in the LM, and turned back to see Command Module Pilot Dave Scott float back up out of the CSM's open hatch, movie camera in-hand. Taking this as his cue, Rusty grabbed ahold of the handrails above- or below, he still wasn't quite sure- and slipped his feet out of the 'golden slippers' on the porch. He couldn't hear Houston directly due to a comms issue, but they could hear him, and Jim and Dave could still communicate with them; so he said out into the void, for Houston to hear, "Okay, here I go. Easy does 'er."

    Next came several minutes of careful maneuvering, as Rusty clambered up and over the LM towards Gumdrop's hatch, un-hooking and re-hooking his tether to the handrails as he did, performing the kind of LM-to-CSM EVA that might be needed on a lunar mission should the hatch malfunction. While there was some minimal banter between the three crewmates as he worked his way up, careful to avoid the large radar antenna situated above the front end of the cabin, Rusty mostly stayed quiet, trying to focus, reporting his status to the crew and to Houston - and trying not to move his head too quickly. Things were starting to spin just a little bit, all these funny angles in space getting him all mixed up. The suit was comfortable, nothing amiss, 'must just be the adrenaline,' he thought, as he carefully crested over the top of the Lunar Module-

    "Watch your tether there, Rusty!"

    Dave's call caused Rusty to turn suddenly - as much as one could in a spacesuit - to try and stop his tether before it caught something fragile, forgetting his efforts to move slowly and avoid the creeping nausea he felt. This quick turn had an equal and opposite effect on his lower half, swinging his legs out and away from Spider's cabin in a slow spin as he reached to adjust his tether; after grabbing it and moving, he reached back up to grab at a handrail and stabilize himself, swinging back around.

    The rapid movement sloshed him around like a fish in a bucket, swinging back and forth; and when he steadied himself again on the LM's handrails, his head didn't quit spinning. Next came a feeling - not exactly familiar, as everything felt a little different in space, without gravity - but one he'd felt about 3 days ago, one that any astronaut or college frat boy can tell you means bad news: a slight tingle in the back of the throat. 'uh oh.' was about all Rusty had time to think, and he got out a quick "Fellas, I think I'm about to vomit-" before shutting his eyes and bracing for the worst.

    Commander Jim McDivitt didn't wait for a response from Houston. This was an emergency, and they needed to act fast.
    "David, get out there as far as you can and pull him in. Rusty, if you can hear me, hang on tight, and get ready to unhook your tether. Houston, I'm gonna need procedures for emergency Command Module repress, as fast as possible." Through a crackle of static, Jim heard Rusty reply, "Copy." as CAPCOM Ron Evans also responded in the affirmative.

    Up at the Command Module, Dave Scott tossed the movie camera back down through the hatch, and grabbed at the tube connecting him to the spacecraft's life support systems, untangling it, before moving outside as fast as he could. Rusty wasn't too far off, barely a few feet; but every second counted when a crewman's life was on the line. This was, probably, the most dangerous moment in spaceflight since Gemini 8 nearly spun him and Neil to death, and Colonel David Randolph Scott was not going to let his second spaceflight be a repeat of his first near-failure, or worse. He grabbed a handrail, pulled himself up towards Rusty, and firmly clasped at his arm.

    "Gotcha, Red Rover."

    ----

    The next few minutes would, in retrospect, be considered the most dangerous of any Apollo mission so far, as Dave Scott pulled Schweickart into the Command Module Gumdrop, closed and secured the hatch, and repressurized the capsule all in a little over ten minutes (the fastest ingress in all of the Apollo Program); and all while reporting back to Mission Control and to Commander McDivitt, who was still working to repressurize the LM by himself before the hatch between the two spacecraft could be opened. In the end, Rusty was alright when Dave was finally able to pry his helmet off - he was soaked in sweat and vomit, yes, but otherwise had made it through the ordeal relatively unscathed.

    ----

    The next day's events were postponed to give the crew a rest and to verify their health, as well as to review everything with Mission Control; the Lunar Module separation and rendezvous with the Command Module didn't occur until two days later than planned into the mission, on March 6th. This went relatively flawlessly - Jim and Rusty flew Spider out away from the CSM while Dave stayed back in Gumdrop; from there, the LM was thoroughly tested over the course of the day - engines, reaction control thrusters, the whole thing - before burning to put the two ships back on course for rendezvous and jettisoning the ascent stage. From there, it was an easy 4 additional days in orbit, made busy only with various small science experiments, CSM testing, and plenty of staring out the windows at the planet below.

    In post-mission reviews, Apollo 9 was seen as almost entirely a success - not a near-fatal failure like Gemini 8, but a triumph, an example of how quick-thinking astronauts and well-built American spacecraft could save lives in unexpected and dangerous circumstances. The LM test was flawless, giving the go-ahead for the final test on Apollo 10 and, hopefully, the landing on Apollo 11, flown by the crew announced in January of Commander Virgil I. "Gus" Grissom, Command Module Pilot Michael Collins, and Lunar Module Pilot John W. Young.



    Thank you once again for reading! Apologies for the delayed update, and for cutting out Apollo 10 (that'll be next time, barring any interludes) - still figuring out posting schedules around school and work. Special thanks to @e of pi for help with planning, historical sources, and general assistance on this one, and as always thanks to @KAL_9000 for creative help, particularly in working out the Grissom segment.

    notes for this time around:
    • Yes, Rusty's actual callsign was Red Rover IOTL - that carried over to TTL given it's the same crew and same mission.
    • I shifted the launch date back to its original February 28th, and had McDivitt not fully develop a cold, as part of a long series of things that probably don't matter - the crew all got colds IOTL, and part of me figures that the immune response from that could've been what made Rusty's space adaptation syndrome so terrible on March 5th, which caused the EVA to be simplified IOTL - an earlier nausea scare on the mission day 1 ITTL means Rusty relies more heavily on Dramamine than IOTL to suppress that nausea, and ends up in a nasty situation because of it. It probably doesn't make sense, but hey, I'm not a medical doctor.
    See you next time around, when we (presumably) cover Apollo 10, and maybe some other stuff, who knows.

    Interlude 3: KORDastrophic Failure
  • Small Steps, Giant Leaps - Interlude 3: KORDastrophic Failure​



    КОРД КОМПЬЮТЕР В: ПОЛЕТ N1-L3, 21 ФЕВРАЛЯ
    ИЗГОТОВЛЕНО ТАСС В 1969 ГОДУ. СЛАВА РАБОТНИКАМ СОЮЗА!

    T-0.00: The command to commence launch came. KORD began its work, activating the engines.

    T+4.51: Engine #12 was a very bad engine, KORD felt. Engine #12 should be shut down. Engine #24 as well, to maintain symmetrical thrust. Not to worry, many more engines still firing. The magnificent, finely-tuned product of the people's labor ascends.

    СЛАВА ПРОЛЕТАРИЯМ МИРА!

    T+25.03: Now Engine #2 misbehaves. Must shut down Engine #2 and its partner. Such silly things, rocket engines. Still 26 working.

    НА ЛУНУ, ВО СЛАВУ СОЮЗА!

    T+68.10: Strange signals from sensors. This must be a problem with turbopump pressure, KORD felt. Shut down all Blok A engines. This will fix the problems, yes, KORD knew this.



    Inside the bunker, All hell had broken loose. For some unknown reason, All 30 first-stage engines on Sergei Korolev's great moon rocket had shut down, all at once. The upper stages were not accepting any command to fire early. All the launch controllers presently could do was watch the readouts in front of them, as their large, expensive, and time-consuming creation disappeared into the distance, doomed to crash back to the steppe some 52 kilometers away.

    Poor Vasily Mishin, inheritor of the great Chief Designer's works, looked as if he may have a heart attack. The Americans were already flying to the Moon, and he could hardly even get his rocket off the ground.



    Thanks for reading! Bit of a short, fun one today - a little vignette on what the Soviets are up to, with Mishin at the helm. Big thanks to @KAL_9000 for the absolutely brilliant idea to do something from KORD's perspective on N1 Flight 1, and for drafting the initial version. No notes this time around. See you next time for Part 4, coming soon!

    "Liberty, Houston. You are go for landing."

    "Copy. 1000 feet. Down at 50."

    Lunar Module Pilot John Young's eyes felt fixed to the readout in front of him. Hardly a moment to glance over at Commander Gus Grissom next to him; he had to focus.

    "500, down at 30. Slow her up a little."

    "350 feet, watch your H-dot."
    "250, down 15. Cut it down."

    "Quantity light."

    Gus grabbed for the hand controller. "I'm gonna go to manual."

    "100 feet, down at 10. Getting a little close."

    In the Mission Operations Control Room in Houston, the mood had shifted from nervous to frantic.
    "Flight, they're coming in too fast."
    "60 seconds."

    There was a steely determination to Gus' voice as he responded, "I can make this."

    John just kept reading off callouts. "50 feet, down 8, 10 forward."
    "30 feet, down 5, 12 forward. Watch your drift."
    "20 feet, down 6, 13 forward. Ease up, ease up!"

    "I can make this."

    "10 feet, down 8-"

    Thunk.

    The Lunar Module simulator's windows went dark. Gus took his hand off the joystick. "Damn."
    Over the comm from Houston, Flight Director Gene Kranz' voice cut in - "Alright fellas, that's lunch. Debrief in an hour."

    "Copy." John ducked out the door of the simulator to find Mike Collins already standing at the base of the stairs, with an almost apologetic look on his face.
    "Bad luck, fellas. That was a close one."
    Gus exited next, shaking his head. "Still think I could've put that down." Vaulting down the stairs, John let out a laugh. "Oh, you put us down alright. Scattered across the lunar surface, the both of us."
    Mike waved his two crewmates over, trying to keep the tone light. "Alright, c'mon, let's get you two lunar casualties some grub."



    February 28th, 1969

    Vasily Mishin was worried. Worried about the N1, worried about Chelomei, worried about the Americans - but right now, he was most worried about the Politburo.
    The Americans had flown a ship in orbit around the Moon, and even now prepared to test their lander in Earth orbit. With just this and then a final lunar orbit 'dress rehearsal' test left, it seemed that they would achieve a landing on he Moon before the end of the summer. Meanwhile, last week's first test of the N1 booster had been a spectacular failure.
    The Politburo demanded results, and they demanded them soon. If he couldn't deliver, the entire lunar program risked cancellation.
    So many possibilities, gone to waste...


    Mishin pored over stacks of design documents, test results, and flight logs. He came to one mission proposal document- the mission proposal.
    If anything could do it, this could.
    He flipped it open to the first page, emblazoned with bold black ink:

    L1 MANNED LUNAR FLY-BY

    In contrast to the N1's disastrous debut, the Proton-launched L1-Zond circumlunar missions had fared much better. Zond 5 had successfully rounded the Moon in September of last year, and while a failed re-entry and landing on Zond 6 had endangered future prospects, Zond 7's successful lunar flyby and return in January had cleared the way for a manned mission to follow. Although Chelomei had led development of the spacecraft and the Proton rocket that would carry it, Mishin had the final say on whether to perform the actual mission, as head of the lunar program.

    Vasily Mishin stared down at the paper before him, and wondered if the risks would be worth the rewards this time. Decisions, decisions...



    May 18, 1969
    9:55 A.M., Eastern Daylight Time


    "Hey Jim, can ya pass me the pepper?"

    The room was awash in a low buzz of overlapping conversation. It all seemed remarkably mundane, an air of casual relaxation of the sort you might find in a local diner, or at a neighborhood cookout in the summer. Here they sat, three men preparing to board a rocket to the Moon, but first they took the time to sit down for breakfast - steak and eggs, the same thing astronauts had eaten since Mercury. As Commander Frank Borman grabbed a pepper shaker from Jim Lovell and shook some out onto his eggs, he couldn't help but grin a bit at the situation.

    Sitting at the table next to him, backup commander Neil Armstrong looked up from the slice of toast he was deftly applying butter to. "So, Frank," he asked, "how does it feel to finally be back in the hot seat?" Frank gave a wistful sigh, half-jokingly. "Too long, my friend. Too long. It's only been, what, 3 years since Gemini 7, but I was starting to feel like I'd never get the chance to go back up." Neil chuckled. "Amen to that, brother. Gemini feels like centuries ago. I'm just hoping I can get a little further than Gemini 8 next time, maybe grab a couple Moon rocks while I'm at it." Taking a bite out of his eggs, Frank quipped, "Hey, be sure to bring me back some. I'm the one who got you this lousy gig after all."

    The two astronauts continued their light, casual conversation for the rest of breakfast, shifting to sports, family, and even politics at one point. It was almost enough to make Frank forget that in a few hours he'd be strapped to the top of a towering pillar of fire as it threw him and his crew bodily off of the planet Earth. Almost.

    May 19th, 1969 (approx. 8:00 A.M., local time)

    The Proton rocket glinted in the early morning light, a monument to Soviet technology standing tall over the Kazakh steppe, all white paint and silver metal. Cosmonauts Vladimir Shatalov and Alexei Yeliseyev stepped off of the transport bus and approached the towering rocket, shaking hands with the ground crew as they went.

    It all feels so unreal. Like this is just another simulation.

    The whole mission was a rush job from start to finish - a Zond capsule originally intended for a test flight, hastily prepared; a series of last-minute safety tests, and scarcely 3 months of simulations; all in an effort to put cosmonauts around the Moon before the Americans landed on it. If any cosmonaut had his own private doubts about the mission, he never dared speak up; either out of bravado, or for fear of retaliation from above.

    The elevator started up with a groan, slowly lifting the cosmonauts and support crew members up to the open hatch. The support crew proudly unveiled a small paper sign they'd made to be carried along on the flight, reading УДАЧИ, РОДИНА 1! with the signatures of as many team members as they could get.

    The spacecraft's descent module would be cramped, especially with the bulky launch and entry suits the cosmonauts wore. One after another, Shatalov and Yeliseyev clambered into their seats, and the ground crew carefully strapped them in. With final harness checks and a thumbs-up from Commander Shatalov, the hatch was sealed and the crew awaited their ride into history.

    Unlike the R-7 and its many derivatives, Proton ran on hypergolic fuels, so there was no seconds-long ignition sequence - just the countdown reaching zero, and a massive, shuddering jolt as the rocket lifted off. Shatalov looked over to Yeliseyev next to him. Over the rattle and roar of the mighty Proton's engines, he shouted, "We're going to the Moon!"

    Rodina 1 was away.



    May 20th, 1969
    Apollo 10 MET 43 hours, 45 minutes

    Nobody ever talks about the smell.

    In December of 1965, Frank Borman and Jim Lovell had spent 14 days in orbit aboard Gemini 7 - the longest spaceflight in history, to date. Two weeks spent cramped in a space roughly the size of a Volkswagen's front seat, things are gonna start to stink. And boy did they, like a rest-stop bathroom in a Florida summer.
    Frank had hoped Apollo would be different. Compared to Gemini's Volkswagen, Apollo was more of a roomy station wagon. Bigger spacecraft, better ventilation, less smelly, right? Well, not exactly, not right now. Not if Seconal had anything to say about it.

    After Schwieckart's near-disastrous EVA on Apollo 9, NASA higher-ups had gotten deadly serious about the dangers of sick astronauts. So, when Frank had woken up early after taking a sleeping pill and immediately let loose from both ends, so to speak, his immediate worry was that Mission Control was gonna abort the whole mission. Frank had managed to steel himself, however - holding down a second bout of diarrhea and vomiting, thankfully - and Jim and Bill had spent the last hour prior to breakfast chasing down whatever ex-foodstuffs had previously called the Commander's digestive system home. The end result was a clean spacecraft, but one that stank to high heaven.

    Keeping this sudden - if hopefully isolated - moment of illness a secret from Mission Control might've saved face, but for safety's sake it was out of the question. On his crew's suggestion, Frank recorded a voice description of the issues into the Data Storage Equipment, so it could be downlinked directly instead of discussing it openly over the comm. Finishing this, he moved to grab breakfast, flipping on a headset to listen in as Jim and Bill conversed with CAPCOM Ken Mattingly.

    "... and we've got the news, whenever you fellas have your morning meals in order."

    Frank looked up from his packet of bacon squares and gave CMP Jim Lovell a nod. Jim responded with his own nod, and called back to Ken in Houston. "We've got a tape dump coming down we'd like you to check the voice quality on, but other than that we're all set, go ahead with the news."

    "Copy. Well, Apollo 10's got most of the front pages. The Houston Post reads 'Apollo 10 Out of This World'. Lots of good press around your TV transmissions yesterday. In other space program news, NASA finally made a decision about the space station. They're gonna stick with the original 'wet workshop' concept, reuse a Saturn IB upper stage. Not much else in domestic news - President Kennedy spoke yesterday evening about future troop withdrawals from Vietnam amid the peace talks, but I suppose that's international. There's one other big thing, but I'll save that for after sports and weather, let you fellas eat."
    "Sounds quite alright to us."

    The three men went about their breakfast as Ken listed off Houston and national sports scores, horoscopes, weather, and other tidbits of news. Mattingly paused for a moment at the end, before continuing.
    "So, there's one last big bit of news that you fellas should know. It's a bit of a doozy- broke late last night, but we figured we ought to wait until all three of you were awake to tell you. The Soviet Union revealed early this morning that their latest spacecraft, Rodina 1, is headed for the Moon, just like the ones last year - but this time, it's got a crew aboard."

    Jim Lovell let go of the bag of corn flakes he was attempting to open. Bill Anders nearly choked on the orange drink he was sipping. Frank was the first to speak up, responding simply, "Well, that's quite the surprise."



    May 23, 1969 (approx. 11 A.M. Moscow time)
    Rodina 1 MET 4 days

    "Rodina, You are go for far-side photography and operations. We will contact you again when signal is re-acquired."

    "Understood, Control. Everything is proceeding well."

    4 days into the mission, Rodina 1's capsule was a mess - The two discarded launch and re-entry spacesuits were shoved haphazardly into the space behind the two crew couches, and the cramped spacecraft had long since lost any sense of organization, with pencils, flight plans, books, and discarded meal packaging floating about the cabin. Control hounded the crew about it, but there was only so much the two men could do to organize such chaos, and Control was 320,000 kilometers away, at any rate.

    ----

    The mission so far had been a relatively uneventful 4 days flying through the great, dark void of space between the Earth and the Moon. The launch had gone successfully, as had engine re-ignition to place the craft on a free-return lunar trajectory. The crew had spent the intervening time photographing the Earth and the Moon (receding and approaching, respectively), verifying the spacecraft's systems operated properly, sampling space food (mostly in tubes), sleeping in shifts, reading one of the few books they'd been allotted (a history of the Great Patriotic War and a copy of Alexander Fadeyev's 1927 novel The Rout most notable among them), and playing chess with a small magnetized travel chess set Yeliseyev had picked up in Moscow.
    Approaching the Moon now, however, there was no time for reading or games - unlike the Americans had done some 30 hours ago, Rodina 1 would not enter orbit, and thus had to dedicate every second of the lunar flyby to maximizing scientific output.

    ----

    Rodina 1 passed out of view of the Earth. Here on the far side, the cosmonauts were well and truly alone.
    The quiet hiss of the life support fans was comforting; it sounded just like it did back in Earth orbit. But, of course, the truth was that the crew of Rodina 1 were farther from Earth than any human beings in history, farther even than the Americans; the mission planners had made sure of this, so that the Union could grab at least one record.

    The two cosmonauts were quite busy as their little spacecraft flew around the back side of the Moon, flipping frequently through their mission manuals and verifying that the suite of scientific instruments and automated cameras were functioning, all the while longingly stealing glances out the small window as the Moon visibly grew in size, expanding to fill the full view. Eventually, Commander Shatalov was able to take a moment to get a proper glimpse out the window, heaving a film camera up with him as he did.

    "Look at that! Incredible!"

    The Moon shone brightly through the window, and the Commander alternated between snapping photograph after photograph, and looking out the window with his own eyes to marvel at the beauty. It was still night on most of the Moon's near side, and so the far side below was almost fully illuminated.
    All too soon however, the Moon began to recede away. Vladimir wished to reach out, beyond the window, and grab a hold of it; to drag himself back, so that he might linger a while in orbit and watch the moonscape below.

    "-dina, Rodina, this is Control, do you read?"
    Taking one last, long look at the Moon so far away, Vladimir Shatalov thought he spotted a glint of light near the Moon, moving over the dark horizon into the sunlight. 'Could it be the Americans?' He wondered to himself, turning to answer Control. By the time he looked back out the window, whatever he might've seen was gone, and the Moon continued to grow ever-distant after their too-short visit.

    May 23rd, 1969
    Apollo 10 MET 4 days, 13 hours

    It was quiet, here on the far side. Quiet and calm, awaiting the lunar sunrise.

    The crew of Apollo 10 was exhausted. The last 15 hours had been some of the busiest of any Apollo mission to date. Frank Borman and Bill Anders had flown the LM Polaris away from Jim Lovell aboard the CSM Genesis, and had spent the day testing the entire lunar orbit procedure short of the actual landing itself - "Everything but the kitchen sink," as Jim had remarked before their departure. This included, most pivotally, flying Polaris down to a scarce 8 nautical miles (47,000 feet) above the Moon, and verifying staging and ascent stage performance. This simulated abort staging would be the pivotal moment - if Polaris couldn't do her job, Project Apollo would be in real trouble.

    It'd been calm and procedural at the time, all technical call-outs and checking flight manuals, but looking back on it now, as the crew settled in for a sleep period, Frank Borman couldn't help but think about just how stressed he'd been in the moment. There he and Bill were, flying low over the Moon, and if they'd messed anything up, flipped just one wrong switch...
    that'd be it.

    Months of training for the mission had kept both him and Bill steady, though, and when he'd flipped the Stage switch on panel 8 from Safe to Fire, Polaris' descent module had detached cleanly and without any trouble, the engine had ignited perfectly some 10 minutes later; and after a few hours of orbit-adjusting, both CDR and LMP had guided Polaris' ascent stage expertly back to a rendezvous with Genesis, their ride home. Frank was glad his stomach had settled after the nasty incident on the way out - keeping your cool was much easier without having to worry about keeping your lunch down, too.

    ----

    And so, that was that. Colonel Frank F. Borman II, Commander of Apollo 10, had done his part in putting an American on the Moon. Here he was now, watching the dark sky out Genesis' window as the sun flared into view over the Moon's dark edge, and wondering to himself what came next.

    Frank already knew that Apollo 10 would be his last flight into space. He'd decided this months ago, when Deke had offered his crew Apollo 8, and then 10; Frank was content to have participated, and had no desire to become the fifth or sixth or tenth man on the Moon a few years down the road. No, Apollo 10 would do just fine; next year would mark 20 years since he'd joined the Air Force, meaning he'd qualify for a pension when he retired, and Frank was looking forward to spending much more time with his family.

    Gazing off into the dark distance beyond the Moon's edge, Frank thought he spotted something catching the light - a bit of debris, perhaps? a bright star, cutting through the gloom? Or was this a sign from on high, a message from Providence telling him he'd done well? Perhaps he'd never know, but he felt comforted nonetheless. Frank Borman didn't know if he believed in destiny, but if there was such a thing, he was hopeful he'd fulfilled his with this mission.

    Rodina 1 MET 6 days, 18 hours

    This was it. 6 days flying through the black void of space, and finally it was time for Rodina 1 to return home to planet Earth. The crew had donned their spacesuits, strapped themselves into their couches, jettisoned the equipment module and support cone, and now sat braced for their capsule to hit the Earth's atmosphere in a 'skip' re-entry. This had only been demonstrated properly once from start to finish - Zond 5 had re-entered on a ballistic trajectory, in such a manner that likely would've killed any cosmonaut aboard; Zond 6 had performed its skip re-entry successfully, but crashed due to a parachute failure; only Zond 7, hardly 4 months ago, had managed to ace both the skip re-entry and the landing.

    Understandably, Vladimir Shatalov and Aleksei Yeliseyev were more than a bit anxious about this marginal success rate, but the two cosmonauts did not comment on it as they conversed with Moscow prior to re-entry. It was only as the capsule began its fiery encounter with Earth's atmosphere that Vladimir Shatalov turned to his pilot, and shouted to him, "Here we go, my friend! Hang on tight, and hope for the best!"

    ----

    May 26th, 1969 (4:30 AM, Moscow time)

    Something had gone terribly awry.

    Trajectory indications days before Rodina 1's re-entry indicated that the capsule might land off-course. The Red Navy had deployed eight ships to the Indian Ocean, just in case. Ground tracking just before re-entry had cemented that Rodina 1 *would* land off-course, somewhere in the northern Indian Ocean. The question of precisely where, however, was now proving difficult to answer. The Borovichy had spent the last 4 hours of the night searching the dark waters, trying to spot Rodina 1's recovery beacon, receiving only a weak signal from the capsule's radio transmitter, and no communication from the cosmonauts themselves. There'd been nothing heard from the crew since before re-entry, and many were beginning to worry that something had gone wrong; that either the capsule had crashed, or that the off-course re-entry had proved too much, and the crew had gone unconscious or perhaps even died.

    Finally, however, off in the dark distance, someone spotted the bright red glimmer of the recovery beacon. The Borovichy's exhausted crew sprang into action, readying a recovery helicopter immediately to assist the cosmonauts, or, in a worst case scenario, to confirm their deaths and recover their bodies.

    Hovering into position over the capsule now, bobbing in the waves, the recovery crew could see that, outwardly, nothing appeared to be wrong. The capsule was intact, so why were the crew not answering?

    Descending on lines dropped from the helicopter above, the recovery team quickly went about unbolting the hatch. Wrenching it open, the first man shouted, "Comrades, are you alright? Do you need assistance?"

    Vladimir Shatalov looked up from the hand of playing cards he was holding as the hatch was popped open - the game had been Aleksei's idea, once the first couple hours had passed; Yeliseyev had been clever enough to smuggle a deck aboard in his suit pocket, although any attempt to play during the flight had been fouled by the lack of gravity.

    The poor Red Navy recovery crew seemed terribly distressed about something - understandable, given the circumstances. Vladimir gave the man leaning in through the open hatch a thumbs-up, indicating that he and his crewman were alright. "We are just fine, comrade. Our radio receiver has stopped functioning, and we were wondering how long we would be left floating here in the sea before you found us!"

    The recovery men laughed upon hearing this, and went to pull the two space travelers out of their capsule, to be flown first back to the Borovichy for some hot cocoa and a rest, and then on to the Homeland, and a proper hero's welcome.

    Interlude 4: Skylab Stays Soggy
  • Small Steps, Giant Leaps - Interlude 4: Skylab Stays Soggy​



    Contrary to what many might assume today, the final design of America's first space station was not the one that Skylab's designers would have preferred. Skylab was originally envisioned very similar to how we know it today, as a "wet workshop" built using a spent S-IVB upper stage. Hardly a few years before its launch, however, many of its designers preferred a "dry workshop" design launched on a special two-stage Saturn V, allowing for far simpler on-orbit station activation and setup. This configuration would also have allowed the Apollo Telescope Mount - one of Skylab's primary scientific elements - to be launched along with the station, rather than on a separate launch vehicle later.

    Ultimately, however, Skylab's design team was forced to hold the course by the Kennedy Administration's commitments to a) complete all Apollo missions up through 20, as initially planned, and b) Not purchase a second production run of Saturn Vs, thus leaving none free for a "dry workshop". Although the Skylab team threw around the idea of upgrading the sole remaining Saturn V test article (SA-500D), much as LTA-2 had been for Apollo 6, NASA simply considered it cheaper to proceed with the wet workshop as already planned.

    Extreme weight-saving measures were taken to ensure that Skylab and its required systems could fit within the Saturn IB's payload envelope. The Multiple Docking Adapter's planned five docking ports were cut down to the minimum 3 needed, greatly curtailing the possibility of future expansion. Anti-slosh baffles within the hydrogen tank had latches and hooks installed on them to serve as equipment mounting points and zero-G handrails. Onboard computers and sensitive equipment were mounted in the MDA and airlock to avoid being exposed to cryogenic fluid. Even the oxygen in Skylab's atmosphere (5 psi; 74% oxygen, 26% nitrogen) would use boiled-off residual liquid oxygen after launch.

    Following Apollo 7, NASA had seven available Saturn IBs in various stages of completion available for use. Six of these were assigned to the Skylab program, with the other set aside for potential future use elsewhere. The Skylab team's initial proposal for "wet workshop" Skylab was to use two of these Saturn IBs, one each to launch the Orbital Workshop and Apollo Telescope Mount, leaving three available for Skylab crews and one for a rescue mission, as needed. However, in 1970, the decision was made to instead launch the Apollo Telescope Mount on a Titan IIIE, now possible thanks to the aggressive series of weight-saving modifications that had been made to Skylab's various components, the ATM included. This freed up a Saturn IB, enabling a potential fourth mission to the station while still maintaining a rescue capability.

    6:47 A.M., Eastern Daylight Time

    Kennedy Space Center LC-39A


    Don't look down. Don't look down. And for the love of Christ almighty, don't drop anything.

    200 feet up the side of a rocket, fixing a leaky hydrogen valve. Normally just another day at the office for NASA's pad crews - but today felt... different.

    ----
    This is Apollo Saturn Launch Control; T minus 2 hours, 45 minutes, 55 seconds and counting to the launch of Apollo 11.
    ----

    The Saturn V felt almost alive, looming there next to the launch tower. It was a living, breathing machine; a 36-story building filled with 2000 tons of flammable cryogenic propellants; a controlled explosion, waiting to happen.

    And the clock is running up there. The fuse on this baby is gonna blow in 2 and a half hours, and they're not holding on account of us.

    ----
    As the prime crew for Apollo 11, astronauts Gus Grissom, Michael Collins, and John Young, are on the terminal part of their trip to the launch pad in the transfer van, it's now making the curve toward the pad. We have discovered a minor problem at the launch pad itself as the crew is about to arrive. We have a leak in a valve located in a system associated with replenishing liquid hydrogen for the third stage of the Saturn V launch vehicle...
    ----

    As the astronauts boarded their ship 120 feet above, the 4-man Red Crew worked diligently in the shadow of the mighty rocket.

    Hydrogen leaks were always fiddly, and this particular valve had been a problem child since the countdown demo two weeks ago.

    "We want you to try torqueing the bolts, then cycle the valve."

    "Copy." -- "OK, yeah, that's not working- no change."

    "OK, stand by. Try it again, we're working some other options down here in the meantime."

    The seconds ticked away, and all they could do was wait while the backroom figured out a new procedure. One of the guys had a transistor radio on him tuned to the PAO loop, and every single count update, every single report, felt like it was directed right at them, the whole mission hanging on one damn valve...

    ----
    This is Apollo Saturn Launch Control. We're all counting on you. And also literally counting. Fix it, or this all falls on you.
    ----

    "OK, we have, um, a bad idea."

    "... Copy, go ahead?"

    "We think we don't need that valve. At all. Can you pour some water over it, freeze it solid? It can't leak if it's solid."

    "Well you're right, that's one dumb idea."

    "It's what we've got."

    "... OK, I guess."

    ----
    This is Apollo Saturn Launch Control. Seriously guys, we're really getting down to the wire here. Less than 2 hours until launch. You'd better hope this works.
    ----

    "OK, holding for the leak test now. What's it looking like?"

    "... Stable back here, any sign of leaks there?"

    "No."

    "OK- it looks like we can manage hydrogen fill with the main valve, you're clear to clear the pad."

    "Roger, Launch Control. Clearing the pad. Red Crew out."

    ----
    This is Apollo Saturn Launch Control; T minus 1 hour, 30 minutes, 55 seconds and counting. -- Here in the firing room, the launch vehicle test team's still keeping a close eye on the status of the propellants aboard the Saturn V launch vehicle. We're back to 100 percent supply with the liquid hydrogen fuel in the third stage. This problem with the leaking valve is no problem at this time.
    ----

    Driving away from the pad, the crew breathed a collective sigh of relief.

    No way some leaky valve stops Apollo 11, not when we're this close. Not on our watch.

    Alexei Leonov sat in the cosmonaut bar in Star City, staring over the counter towards a shelf on the wall, on which sat a television set. The thing appeared tired, all wooden and brushed metal construction and scuffed edges, looking like it'd been dropped more than a few times - in other words, probably brand new from a factory in Leningrad. On the screen, in fuzzy black-and-white, an image that seemed both familiar and alien all at once: a massive rocket, standing proud on one of the enormous pads of the American cosmodrome.

    If Alexei squinted, he could almost imagine the image on the television was instead of Baikonur, and the rocket one of theirs. Any hope of this self-illusion was shattered, however, by the voices of the American launch control issuing from the speaker. Despite the strange language they spoke in, Alexei could easily recognize pre-launch checks, even before the slightly delayed Russian translation. It wouldn't be long now - They will be launching soon, and it will of course go perfectly, as it always does, he thought to himself as he took another sip of his drink.

    Alexei tore his eyes from the small screen for a moment to tiredly glance around the room. He was not by any means the only one watching - Star City wasn't exactly overflowing with TV sets, and for many of the cosmonauts, trainees, and Air Force men in the room, this would be their only opportunity to watch an American rocket launch live on television. On the walls hung a large poster featuring a cosmonaut holding a hammer and sickle, and framed and signed photographs of various cosmonauts. Yuri Gagarin, of course, took pride of place; next to him photographs of Vladimir Shatalov and Aleksei Yeliseyev, and a photo of the Moon taken on their flight; and next to them- a portrait of Leonov himself in his spacesuit, and a still frame from footage of his EVA. Alexei had taken to thinking of that portrait, those pictures, as The Great Soviet Hero, The First Spacewalker; it helped to separate himself from the deified image the Party had made of him, to remember who the real Leonov was.

    Alexei Leonov Voskhod 2.png


    The portrait smiled back at him naïvely, the younger man in it still not yet knowing how close he would soon brush with death on that fateful first spacewalk. Alexei mused briefly of throwing his glass across the room at it, but thought better of it, and looked back towards the television. He caught the eye of Valeri Kubasov down the bar as he did, who raised his glass solemnly - "To the good health of the American astronauts," he grimly stated in a toast. Alexei raised his own, and responded with a defeated laugh, "May their mission abort safely and smoothly."

    9:30 A.M., Eastern Daylight Time


    Robert Francis Kennedy, the 37th President of the United States, had accomplished quite a bit in his 43 years of life. Attorney General, Senator, husband, father of 11; The second presidential candidate in US history to survive an assassination attempt, the first sibling of a president elected president; one of the men behind the Civil Rights Act of 1964, and now, hopefully, an honorable peace to end the war in Vietnam.

    All that aside, though, there was perhaps one thing that the President hoped to be remembered for, long after he was gone; in the longest term, the nation- no, the world, the human species, would remember this moment, and the next week that followed it, above all else.

    Robert Kennedy stood in the stands at Kennedy Space Center, gazing out over the Florida marshland towards Pad 39A where Apollo 11 prepared for launch. Ethel stood beside him, her hand intertwined with his; their 7 eldest children were scattered throughout the stands nearby. His eyes, though, remained affixed on the towering black-and-white rocket and bright red launch tower in the distance, his mind lost in thought.

    Whose legacy will this be, really? The moonshot was Jack's idea, his big political push - hell, the Space Center's named after him. Johnson's administration saw it all through, the development, keeping it on pace; do I really deserve to be remembered as "the President who put man on the Moon" when I've only been in office hardly 5 months?

    He'd all but tuned out the monotone voice over the loudspeaker reporting the mission status. It was only when the light hit him, and then the deafening sound a few seconds later, that it really felt real. The massive Saturn V, which his brother had played such a huge part in creating, roared to life and began its slow, steady climb off the pad.

    We've come a long way from Cape Cod, Jack.

    The sound of it was immense, a near-deafening roar that rolled across everything. The bright white flame pouring from the rocket's tail end pierced the blue Florida sky, bright as the sun; it seemed almost divine, as if mere mortal man had been outclassed by that which he had created. Robert stared right up at it, sunglasses perched forgotten on his forehead, watching as Apollo 11 built up speed and followed its trajectory skyward.

    As the deafening roar faded to a distant rumble, the sounds of the crowded stands returned - cheers, clapping, "oooh"s and "aaah"s at this greatest fireworks show in history. Someone shouted "Go, baby, go!", and Robert wondered for a moment who it was - until he realized it had been him.

    5:30 A.M., Eastern Daylight Time


    Steak and eggs. Always steak and eggs.

    Virgil Ivan "Gus" Grissom had been an astronaut for over a decade, and yet had attended surprisingly few pre-launch breakfasts.

    He hadn't gotten a pre-launch breakfast on Mercury-Redstone 4 - launch had been moved up by an hour, the day after a previous scrub; nobody'd thought to inform the chef the morning of, so the second American in space had experienced his 15-minute flight - and subsequent near-drowning - on an empty stomach. He'd have given anything for some steak and eggs during that ordeal, but the canteen food aboard the USS Randolph afterwards did just fine.

    Before Gemini 3, he and John had had steak and eggs with Al Shepard and some of the NASA brass - and of course, John had packed lunch for orbit, without his knowledge. That was by far the more memorable of the day's meals, even if it did piss Mission Control off after the fact.

    For Apollo 7, the crew had eaten steak and eggs with Deke Slayton and the backup crew; nothing eventful that time around.

    Now, here he sat again, at that same table, eating pretty much the same meal he'd eaten those two times before. It was a bit of a sparse one again this time - just him and his two crewmen, Deke again, and backup Command Module Pilot Ken Mattingly. It was quiet, relaxed, intimate - and yet, there was a tangible excitement to the air.

    ----

    Suiting up was the same as always, a pack of white-clad technicians securing gloves and tubes and helmets with the practiced precision of a racing pit crew and the careful pace of an operating surgeon.

    The walk out to the van felt stranger than all the ones before, for all three men. NASA staff lined the halls, clapping and waving as the cavalcade made their way past. Ken was already waiting beside the door, and shook each crewman's black-gloved hand as he passed. As the crew stepped through the door outside, the pre-dawn darkness was broken sporadically by the flash of a hundred camera bulbs, as the gathered crowd of reporters rushed to capture an image of the three men. They looked to the crew with a distant reverence, as if they were ancient gods come down from Mount Olympus. Gus clutched his oxygen supply tighter out of nervous instinct, exiting first, but waved and flashed a smile nonetheless. Mike came next, nodding politely to the crowd. John carefully kept pace behind him, beelining straight for the van. The sky above seemed to almost glow with a dark, rich blue, the first light of day barely bleeding into the void of night.

    The transfer van, at least, was a moment of respite - the driver and suit techs respectfully avoided talking much, everything already having been said during suit-up; the three crewmen were left to their thoughts, on the long drive out to the pad.

    ----

    There she stood, then; the Saturn V, in all her glory. Great billows of white vapor swirled off of its gleaming black-and-white structure, puffing and hissing like some great beast awakening from its slumber. Gus almost felt the need to comfort the mighty rocket, seeming almost impatient there on the pad.
    I know, babe. We're on our way. Hang in there.

    ----

    Walking across the access arm into the White Room, Gus was greeted by a familiar sight - the smiling, bespectacled face of Pad Leader Guenter Wendt. He greeted Gus like an old friend, and produced from behind his back with a flourish a bright orange life jacket, labeled "Lunar Commander Safety Equipment" in bold black font - a good-natured jab that only Guenter could get away with, of course, in reference to Gus’ first flight on Mercury. “I’ll be sure not to sink this one,” Gus laughed, clapping Guenter on the shoulder.

    Michael Collins was next into the White Room, greeting the technicians cordially as he moved towards his ultimate destination. He paused for a moment at the hatch, gently placing a gloved hand on the side of the Boost Protective Cover over the capsule. For the next 8 days, Columbia, this spacecraft, would be effectively his responsibility. Sink or swim, landing or no, this beautiful machine was in his hands the moment they were off the Earth.

    ----

    In the capsule, already strapped into the leftmost chair, Gus reviewed some pre-launch settings with backup Lunar Module Pilot Ed White, very much dressed true to his name in all-white coveralls, who sat crouched in the Lower Equipment Bay alongside a suit technician.

    "Okay, got your ELS auto switch on up?"
    "ELS is up."
    "Delta-V CG CSM?"
    "CG CSM."
    "Event timer reset and start switches should be center."
    "They're center."
    "Alright, that’s all, Gus. Say, how's about you scoot over a bit, see if we can't share the seat? I don't weigh more than a couple of moon rocks."
    Gus laughed. "Not this time, Ed. Hey, you'll be walking up there yourself, next couple flights or so. John and I make sure this whole thing works, and then you're off to parts unknown on Apollo 14 or 15 or some such."

    Eventually, both Mike and John joined Gus aboard Columbia, strapped into the center and right chairs respectively. Ed clambered out of the LEB and up through the hatch, and Mike gave one final thumbs-up to Guenter before the pad crew closed and sealed the hatch. The crew of Apollo 11 were cut off from the world.

    This is Apollo Saturn Launch Control. All elements are Go at this time for the launch of Apollo 11 as we continue the countdown. All three astronauts now aboard the spacecraft with the hatch sealed...

    Slowly, the minutes ticked down to launch.



    Apollo 11 MET 0 Hours, 0 Minutes

    “LIFT-OFF! We have a lift-off, 32 minutes past the hour. Lift-off on Apollo 11.”

    "Lift-off. Clock running, yaw program."

    The vibration was intense, and the sound deafening. 100 meters below, the five massive F-1 engines strained against the weight of the mighty Saturn V, gulping down 20 tons of fuel per second as the vehicle began its ascent to orbit. All three men could feel as the engines swiveled and gimbaled. Gus continued to call out events as they went.

    “Roll program.”
    “Roger, Roll.”

    “Roll complete, pitch is tracking. Beautiful.”

    The Saturn V clawed its way into the sky, faster and faster. Abruptly, the noise ceased: the ship was now moving so fast it was outrunning its own sound.

    ----

    “Apollo 11, Houston. You’re good at 1 minute.”
    “Roger.”

    The F-1s burned ever harder, the acceleration mounting - 2 G’s, then 3, nearly up to 4, pushing the crew down into their seats.

    “Inboard engine cutoff.”
    The acceleration stuttered back down to 3 G’s as the central F-1 shut off to lessen the stress of staging, before rapidly climbing back towards 4. The other four engines burned on still, the first stage’s remaining fuel rapidly dwindling.

    “11, you are go for staging.”
    “Roger, go for staging.”

    The crew braced for staging. John, remembering previous crews’ comments about S-IC staging, called out to his crewmates, “Here comes the train wreck!”
    The remaining four engines cut off, their job complete; the three men were briefly thrown against their seatbelts as the S-IC ceased firing.

    The S-IC fell away with a clatter of retrorockets, while ullage motors on the interstage fired to settle the fuel in the S-II. All five J-2 engines roared to life, boosting the upper portions of the stack away from the spent S-IC. Staging complete, the interstage skirt fell away, tumbling in the exhaust from the S-II’s engines.

    The S-II burn felt much smoother than the rattle of the S-IC, helped by the fact that the rocket was now beyond much of the atmosphere. The monumental shaking had largely subsided, replaced by a smooth, slow buildup of G’s back up to a peak of around 2, feeling almost gentle after the S-IC’s high of 4.

    “There’s the tower.”

    The Launch Escape Tower perched atop the spacecraft jettisoned, taking with it the Boost Protective Cover and uncovering Columbia’s remaining windows. Mike looked over to John on the right seat - who, to this point, had been the only one of the three with no view of the outside - and remarked with a laugh, “Hey, they finally gave you a window to look out of!”

    ----

    It was now just over six minutes into the week-long flight, and the vast majority of Apollo 11's launch mass had already been lost. The J-2 engines continued burning as hard as ever, still several kilometers per second short of orbit, clawing their way out of the deepest gravity well of any solid object in the Solar System.

    With a jolt, the center engine of the S-II cut off as expected to reduce pogo oscillation. 90 seconds later, so too did the outboard engines cut off. The S-II smoothly fell away from the S-IVB.

    “Staging, ignition.”
    “Roger, 11. Thrust is go.”

    The third stage’s single J-2 engine burned proud and true, pushing Apollo 11 through the last leg of its ascent with no issues. After some 2 minutes and 30 seconds of burn time, the engine cut off. Apollo 11 was in orbit.

    “SECO. We’re showing 101.4 by 103.6.”
    “Roger, shutdown. We copy 101.4 by 103.6.”

    A loose flight plan floated up from the Lower Equipment Bay, as if to greet the crew; a reminder that they were, in fact, in space once more.

    “Okay 11, The booster has been configured for orbital coast. Both spacecraft are looking good. Quite a show from down here.”



    July 20, 1969
    Apollo 11 MET 99 hours, 32 minutes

    “It's nice and quiet over here, isn't it?”

    It’d been a long, busy journey out to the Moon. Over the course of the last 4 mission days, Apollo 11 had aced every single objective. TLI occurred without issue; CSM Columbia had flown like a dream during Transposition & Docking, and had arrived at the Moon with LM Liberty in tow. 13 orbits of the Moon later, here they were, on the precipice; Two crews had come here before them - three, if you count the Russians - but none had taken that final step, that last leg of the journey to the surface of another world.

    Aboard the Command Module, Michael Collins prepared for undocking. Tunnel closed and hatch sealed, Columbia and Liberty were very nearly two independent spacecraft; all that Mike needed to do was flip a couple switches on the panel in front of him, breaking the final docking connection holding the pair together.

    “We got just about a minute to go. You guys all set?”

    Over the comm from Liberty, Gus Grissom responded in his calm, even tone.

    “We’re lookin’ good over here on our end, Mike. Hold down the fort for us topside. Ready when you are.”

    “Roger that. You cats don’t make any trouble down there.”

    15 seconds later, with the flick of a switch and an audible thunk, the two spacecraft separated. Over the next few minutes, Liberty and Columbia drifted apart, correcting for the motion of separation before holding a short distance from one another for inspection. The two spacecraft were back over the near side now, and the duet had once more become a trio as CAPCOM Charlie Duke now occasionally chimed in.

    “Okay Liberty, If you are ready to copy the PDI data, I have it for you…”

    Out the window, Mike got his first good look at Liberty since they’d pulled her from the upper stage 4 days ago. She was a spindly, fragile-looking thing, a contraption of angled grey metal up top with a crumpled skirt of gold and copper-colored foil down below; a strange insectoid creature very fitting for the alien world she was designed to land on. The craft pirouetted end-over-end in a careful yaw maneuver, allowing both Michael and the camera mounted in the window to survey her for any issues - of which both found none.

    “I think you've got a fine looking flying machine there, Liberty, despite the fact you're upside down.”
    Gus responded over the comm in a deadpan, “Maybe everyone else is upside down, and we’re the only ones right-side up.”

    “Apollo 11, Houston. You are go for separation burn.”

    Apollo 11 MET 102 hours, 38 minutes, 26 seconds
    Callsign: Liberty

    “Program Alarm. 1202.”

    The first lunar landing was, so far, turning up plenty of problems to make up for the near-flawless launch and coast out. First there’d been comms issues leading up to Powered Descent Ignition. Then, there’d been trouble with the RCS. They’d gone past their mark early as well, meaning they were gonna land longer than they’d expected to. And now, the computer had decided that right this moment, 33,000 feet above the Moon and dropping fast, was the perfect time to start complaining as well. And of course, like any good computer problem, it was one Gus hadn’t even heard of in training, let alone seen in the simulator.

    “What’s a 1202?” He looked to John, who glanced up from the console in front of him just long enough to give an unspoken look of ‘how the hell should I know?’ With a tense exhale, Gus called home.

    “Houston, what’s the word on that 1202 Program Alarm?”

    CAPCOM Charlie Duke sounded stressed, but came back with good news a few seconds later: “Roger, Liberty, you’re, uh, we’re Go on that alarm.”

    That’s all I needed to hear.


    Gus and John spent the next couple minutes focused almost entirely inside the LM, making sure their computer troubles were all in order. The Lunar Module pitched over towards the horizontal, the lunar surface now much more visible, without Gus ever catching more than a glance out the window. What he did see all really looked the same - it was hard to gauge distance on the Moon, no air meaning no normal depth perception, so the craters out there could be 2 feet or 2 football fields wide, or anywhere in between.

    Liberty, Houston, you’re Go for landing.”
    “Copy, Go for landing.”

    John, as always, kept his eyes on the numbers and called out altitude as they went.

    “3000 feet. Oh for- Program Alarm. 1201.”

    It took every ounce of Gus Grissom’s willpower not to shout something very unprofessional at this. He relayed the alarm to Houston, and kept on flying.

    Don’t you give up on me now.

    Liberty’s RCS banged and rattled, the computer holding her steady through descent as the fuel in her tanks sloshed back and forth.

    It was only maybe a second or two after he’d relayed the alarm that Charlie responded, rather urgently, “We're Go. Same type. We're Go.”

    “2000 feet, down 50.”

    It was only at this point that Gus got to look, really look, out the window. He did not like what he was looking at one bit. Right smack dab in front of them was a massive crater about the size of a football field, with huge, blocky boulders strewn all around it. He needed to know where the computer wanted to land them, and fast.

    “John, what’s my LPD angle?”

    “47 degrees.”

    Glancing to the markings etched on his window, Gus could spot where the computer was aiming. It was precisely what he didn’t want to see - they were targeted for the slope just north of the crater, in the middle of a boulder field.

    “We’re headed for a rough spot. I’m going to manual.”

    With a flick of the hand controller, Gus was now fully in the driver’s seat. He pitched Liberty forward, picking up horizontal velocity to avoid the blocky crater. John kept calling the numbers.

    “400 feet, down at 10. 58 forward.”

    “350 feet, down at 4.”

    “300 feet, down at 4. 46 forward. Slow her up a little.”

    On past the crater was a decently flat area, as flat as the pockmarked lunar landscape could reasonably be. Gus gently pitched the LM back towards vertical, slowing down to find a landing spot somewhere ahead. He spotted a nice flat plain ahead past a smaller crater, clear of any large rocks.

    “I’ve found my spot.”

    “250 feet, down at 3, 18 forward. Shadow out the window.”

    “200 feet, down at 3. Ease it down.”

    “160 feet, 5 and a half down. Quantity light, 5 percent fuel.”

    Gus mentally kicked himself at this callout - it’d been in the checklist to ask. ‘Damn, I didn’t ask for the fuel earlier!’

    “120 feet, 6 down, 9 forward.”

    “100 feet, 3 and a half down, 9 forward.”

    Liberty, Houston, 60 seconds of fuel.”

    Gus now had one minute of gas left in the tank before he’d either have to find a spot to land, or cut his losses and abort.

    There’s no way we’re getting this close and not going all the way.

    Out the window, the static lunar landscape sprang to life; slowly at first but increasing by the second, a steady flow of dust began radiating out from under them as Liberty’s engine exhaust blasted the surface.

    “75 feet, down at 1, 7 forward.”

    “40 feet, down at 2. Getting a little dust.”

    ‘Yeah, no shit.’ Gus thought to himself. By this point the dust had all but consumed the lunar landscape below, with only a few rocks poking through the steady flow enough to be seen.

    “30 feet, 2 and a half-”

    “Thirty seconds.”

    “4 forward, watch your drift. 20 feet, down a half.”

    Liberty wobbled slightly - she was picking up some drift from somewhere, and Gus tried to correct to even it out. Out the window, the lunar surface had disappeared, blanketed completely with an obscuring sheet of dust kicked up by the engine.

    “Ten sec-”

    “Contact light!”

    On the console in front of them, a small blue light flicked on, indicating one of the probes had hit home. Reflexively, Gus’ hand moved immediately to shut off the engine.

    “Shutdown!”

    Liberty dropped to the surface with a muffled thud. Out the window, the seemingly endless stream of dust abated rapidly, as though a faucet had been cut off; Gus marveled for a moment how the dust disappeared off to the close horizon, leaving no trace or cloud behind - and everything was still.

    There was a brief second of silence, before John kept rolling with procedure. “Okay, Engine Stop. You’ve got your ACA out of Detent?”

    Gus nodded. “ACA out of Detent, Auto.”

    The pair went through the necessary steps of safing the descent engine and configuring the computer in case of an on-the-ground abort. It took about 10 seconds for a shocked-sounding Charlie Duke to call back, “We copy you down, Liberty.

    “- Okay, Engine Arm off.” Gus keyed his mic over to voice-activated comms, and finally gave the call back to Earth.

    “Houston, Liberty Station here. Man is on the Moon.”

    John cracked a smile next to him, and off the comm, remarked, “Make no mistake about it, fellas.”

    The relief in Charlie’s voice was tangible as he responded, “We copy you, statio- ah, Liberty, we copy you on the ground. You got a bunch of guys about to turn blue. We're breathing again. Thanks a lot.”



    Apollo 11 MET 102 hours, 57 minutes
    Callsign: Columbia

    Liberty, Be advised there're lots of smiling faces in this room and all over the world. Over.”

    “Well, there’s certainly a couple of ‘em up here on the Moon.”


    “And don’t forget one in the command module.”

    ----

    Of every person employed by the National Aeronautics and Space Administration, only one man would have absolutely no access to a television on which to watch Gus and John’s historic first walk on the Moon. He’d have to be content with listening in, hearing descriptions and seeing newspaper stills after the fact. That man, of course, was Command Module Pilot Michael Collins, in orbit around the Moon aboard the CSM Columbia. And frankly, he was more than okay with that.

    The job of a Command Module Pilot, to those not very familiar with spaceflight, might sound boring; you were the guy who sat up in the capsule while your two buddies got to go run around on the Moon picking up rocks and planting flags and all that fun stuff, right? Well, not precisely.
    The job of a Command Module Pilot, as Michael Collins had come to appreciate it, was probably the most important one on an Apollo mission. The CMP had to keep the spacecraft up and running for over a week; this complex, delicate machine needed constant tending to ensure she’d be capable of returning the crew safely to Earth, moon rocks in tow. In case of an issue mid-flight, the CSM’s engine would be the primary abort option; without that engine, this spacecraft that he was tasked with upkeep and flying, none of the three crewmen of Apollo 11 would be able to get home in the first place.

    And then, there’s the benefit they don’t tell you about on the job application: you get to have a whole spacecraft to yourself, for over an entire day. The Apollo Command Module was built to house 3 men relatively comfortably for a week-long trip to the Moon, so with two of those men not presently aboard, Columbia felt like a luxury hotel suite. Mike was able to keep everything neat and tidy, use up as much space as he wanted, and hell, even change his socks or go to the bathroom without feeling like he was inconveniencing other people in a shared space.

    Columbia orbited 60 nautical miles over the Moon, orbiting once every hour and 58 minutes. For 45 or so of those minutes, the spacecraft was over the far side, completely out of contact with Mission Control; 45 minutes of peace and quiet, catching up on tasks, having a snack and listening to some music, or even just staring out the window at the lunar surface as it passed below, from light into darkness.

    Gus and John could keep their lunar surface, just fine. Michael Collins was more than happy right where he was, in orbit.



    Apollo 11 MET 105 hours, 15 minutes
    Callsign: Liberty Station

    Gus and John were on the Moon to stay. Or, at least, they wouldn’t be leaving any earlier than planned. They’d gone through the motions of configuring Liberty for her stay on the lunar surface, and they’d now removed their gloves and helmets and gotten, to an extent, a bit more comfortable in the cramped LM cabin.

    At this point, the mission checklist called for a meal, and then 4 hours of sleep; It’d always been intended to potentially move this, and perform the EVA before, instead of after, sleeping, should everything go well; Gus and John had found themselves not too tired after landing and post-landing procedures, so they’d verified with Mission Control a change in schedule. They’d concurred, and the EVA had been advanced by 4 hours in the timeline.

    The meal period still remained, though; having finished all their tasks for the time being, Gus went to grab the appropriate packages from where they’d been packed away. As he did so, John casually remarked, “What’s on the menu for today?” Gus shrugged as best he could in his suit. “Same stuff as always, I suppose.”

    As Gus turned around, package of bacon squares in hand, John pulled something out of his spacesuit pocket and presented it to the Commander with a wide grin across his face. “Now,” he said, “How about something a little more special for the occasion?”

    Sound does not travel on the surface of the Moon, due to it being in a vacuum. If it could, Gus Grissom’s laughter probably could’ve been heard for miles.

    In John Young’s hand, neatly vacuum-sealed in plastic, was a delicacy that hadn’t been to space since 1965. Just like every other bit of food on an Apollo mission, it was labeled with black text on a white sticker:

    CORNED BEEF SANDWICH

    And it was as it was labeled - an honest-to-God deli sandwich, right here on the Moon.

    When Gus finally stopped laughing, his first word to John was, “How-?”

    “I made a couple of friends in the NASA kitchen staff.” He cut in. “This was a personal favor.”

    “How’d you get it approved? I can’t imagine- oh.”

    The look on John’s face said it all. Gus didn’t ask any more, but looked at the LM console briefly. “We’re on Push-to-Talk, right?”

    “Yup, I checked it a few minutes ago. We’re clear.”

    “John Young, you evil mastermind.” Gus laughed, working to open the gift John had handed him. Once he did, he took a bite.

    It was relatively damp, as one might expect a deli sandwich vacuum-packed in plastic for some amount of time to be; but it wasn’t all that unpleasant. Gus had paid money for worse sandwiches in his life. This one, though, in this moment, was absolutely priceless.



    July 21, 1969
    Apollo 11 MET 109 hours, 22 minutes

    “Okay Gus, we’ve got a good picture of you coming down the ladder now.”

    Halfway down the ladder, and fully in Liberty’s shadow, Gus Grissom gingerly moved his booted foot to the final rung. There was a good 2 feet between him and the footpad; the legs had been designed to crush as shock absorbers in case of a hard landing, but Liberty had touched down relatively soft.
    In between his arms and running back up the ladder into the hatch, the LEC tether was near-tight; John had been feeding it out as Gus progressed out the hatch and onto the porch. It was a bit of formality, an extra little bit of safety for the first mission - while everyone was pretty sure the ladder would be no trouble, just in case of a slip, the Lunar Module Pilot would be able to catch a Commander and prevent a nasty fall.

    “Copy Houston- I’m gonna step down to the footpad here. Give me a little slack there.”

    Carefully, Gus slid his boots out from the ladder rung and dropped, slowly, to the footpad below. He stood there for a moment, then, with hardly a push, jumped back up towards the ladder; sure enough, it was beyond easy to reach the bottom rung in the low lunar gravity. With one last little push down, Gus’ boots landed squarely on the footpad once more, silently.

    “Okay, I can jump back up to the ladder pretty easily. It’s about a 2 foot gap, doesn’t look like the strut there collapsed much at all.”

    From back in the Lunar Module, John retorted, “Doesn’t sound like too much trouble.”

    Gus looked down to the ground around him. It looked solid enough; the texture seemed somewhere between wet beach sand, talcum powder, and charcoal. Liberty was a fair bit heavier than he or John, and she certainly seemed to be doing just fine; the footpads were planted firmly on the ground, no more than maybe an inch into the dust.

    “John, this is Houston. If you could set the sequence camera to F/2 and 1/160th…”

    When John and Bruce finished this short technical exchange, Gus spoke up, glancing around the LM as he did.

    “Okay, I’m down on the pad now. I’m in the shadow of the LM. Boy, does that sun look bright though.”

    He paused, looking down to the ground below once more.

    No more point in delaying this, I suppose.

    “Gonna- go ahead and step onto the surface.”

    Gus lifted his left foot from the footpad, and carefully, as if testing a rickety old staircase to see if it’d hold, placed his boot onto the lunar surface. The dust compressed around his boot like a thin, fresh-fallen layer of powder snow, but it held his weight firmly. Pulling some slack from the LEC tether, Gus shifted again, placing his right boot onto the surface now as well.

    ----

    In the run-up to the mission, once it’d been chosen that the Commander would be the first one out of the LM hatch, and thus, the “first man on the Moon,” Gus had been asked dozens of times what his first words on the surface would be. He’d always smiled, laughed it off, said something about how “I’ll think of something appropriate to the moment,” and continued on. The last time someone had asked him had actually been just this morning, over breakfast aboard Columbia, when Mike had brought it up.

    “Frankly, Michael,” He’d told him, “I still don’t know. What are you supposed to say in a moment like that?”

    "Suppose we'll see when it happens, huh?"

    He hadn’t given it any more thought after that; far too much to do, focus to be dedicated elsewhere in a mission like this.

    ----

    Standing here now, both feet planted firmly on the surface of another world, Commander Virgil I. “Gus” Grissom finally found the words - short, simple, and meaningful.

    “Mankind’s adventure is only beginning.”



    Apollo 11 MET 110 hours, 14 minutes

    “… And there’s a tendency to want to lean forward as you move, to counterbalance the weight of the PLSS, but I’m able to sustain a steady pace without too much difficulty.”

    The Moon was, to state the obvious, unlike anywhere else John Young had ever been. Grainy photos from the Surveyor landers and orbital photography from Apollos 8 and 10 didn’t quite do justice to how… alien it all was. It just didn’t quite feel real.

    The low gravity was, while completely new, also somewhat familiar - to an extent it could be simulated with wires on the ‘Peter Pan’ rig back on Earth, though the real thing felt much smoother.
    From afar, the landscape could be just another plaster-of-Paris mockup; but if you really looked, you could spot the detail in every little rock and boulder, every mound of dust, absolutely crystal-clear, with no depth of field.
    The Sun was harsh and unfiltered; stark and jarring against the pitch-black sky. In the shadow of the LM you might be able to spot a bright star or two, but out here in the daylight the sky was empty; devoid of all but the Sun, the blue half-circle of the Earth high above, and the bright dot of Columbia orbiting overhead, which Gus thought he’d spotted earlier.
    Everything else about this place - the desolate landscape, the gravity - had an edge of familiarity to it, to an extent. That sky, though… Something about being in full, bright sunlight while the whole sky was black and empty just got to him, made him feel like this was all some funny special effect, or a dream; like somehow he’d close his eyes and wake up back home in bed.

    Liberty, this is Houston. Could we get both of you on the camera next to the flag for a minute?”

    “Uh, roger, Houston.”

    Gus walked around the LM into the camera’s field of view, joining John where he’d been demonstrating lunar mobility for the camera. He kicked up little fans of dust as he went; another reminder of how different the Moon was, as with no air to disperse it, the dust moved completely differently than dirt kicked up on Earth would.

    CAPCOM Bruce McCandless’ next call, though, made John forget all about the gravity, the sky, the dust, and just about everything else.

    “Gus and John, the President of the United States is in his office now and would like to say a few words to you. Over.”

    Gus responded promptly, “Of course, that would be an honor.”

    “All right. Go ahead, Mr. President. This is Houston. Out.”

    Across the void of space between the Earth and the Moon, so far that it took light and radio transmissions over a second to traverse, the voice of Robert F. Kennedy rang out over the comm.

    “Hello, Gus and John. I’m speaking to you by telephone from the White House, and this is surely one of the most historic moments in mankind’s history, as I am sure every American and people all over the world can agree. With your historic mission, we have accomplished the goal set out by my dear brother, when he spoke to the Congress only a few short years ago. With your landing on the Sea of Tranquility, you have proven that man can travel to other worlds in peace and tranquility, for the betterment of us all. All the people of planet Earth are together in this moment, joined in our pride for this great accomplishment, and in our prayers that you will return safely home.”

    Standing next to the flag, John gave it a salute as Gus responded - but he wasn’t really listening to the Commander at this point. It’d only just really hit him, fully, the enormity of this moment.
    Maybe it was the close horizon, or the bright sun in that dark, empty sky, or the leader of the free world calling to speak with them; it finally, really struck him that this was more than just another day at the office.

    We did it. We really did it. We’re on the Moon.

    Apollo 11 MET 121 hours, 40 minutes

    The Moon tends to be associated with the night sky, and thus with sleep. At this point, the only two men who’d actually tried sleep on it were starting to find that pretty ironic.

    “Liberty Station, Liberty Station, Houston. Over.”

    “Good morning Houston.”

    It’d been just under 7 hours since they’d wished Houston “good night” after finishing out some final checklist items. The intervening time had been spent attempting, and largely failing, to sleep. Any number of issues were to blame - suit temperature, sound, excess light through the (poorly) shaded LM windows, residual excitement from the day’s events - but the end result was the same; Gus and John, sat on the ascent engine cover and curled on the floor respectively, had gotten maybe an hour of sporadic, fitful sleep.

    ----

    The next couple hours passed in a blur - activating LM systems, verifying ascent angle and antenna position and a million other little things before finally, after just over 21 hours on the lunar surface since John had called Contact, it came time to depart.

    “Okay, DSKY blank.”

    Gus went down the line with the final checks, flipping switches to the correct positions to arm Liberty’s engine and separate the ascent stage, for the first rocket launch from the surface of another world.
    “Abort Stage, Engine Arm, Ascent. Twenty seconds. On your count.”

    Watching the computer carefully, John started a countdown at the right moment.

    “10. 9. 8. 7. 6.”

    Gus’ hand hovered over the console, waiting.

    “5. 4. 3. 2. 1.”

    “Proceed.”

    Gus flipped the switch, and with a noiseless jolt, Liberty lifted off from the Moon. Out the window, shreds of gold and silver flew through the airless sky as Liberty’s ascent engine blasted the descent stage. John thought he caught the flag moving in the blast, but couldn’t confirm whether it’d stayed standing before looking back to the console to keep the ascent on track.

    “All that debris. Man, we’re moving. Got a LM shadow, 34 feet per second up.”

    “Houston, Lady Liberty is on her way.”



    July 26, 1969
    9:34 A.M., Central Daylight Time


    Two days back on Earth, and John Young was glad to be on solid ground.

    The latter half of Apollo 11’s mission had gone more or less perfectly - rendezvous, docking, trans-Earth injection, the coast from the Moon to the Earth, and re-entry passed by without note. He and Gus had slept like the dead once they’d got back up into orbit; zero-gravity, along with not having to wear a spacesuit, made for a surprisingly comfortable night’s sleep.

    Splashdown was the only thing in Apollo 11’s latter half that’d had some trouble; Columbia had tipped over in the ocean, and the three crewmen had spent a moment dangling from their straps before the landing bags had inflated, returning her to a slightly more comfortable position until the Navy frogmen arrived to fully right her.

    Then had come, in John’s opinion, the silliest part of it all; the Navy cracked open the hatch and tossed in three Biological Isolation Garments, and the crew doffed their spacesuits and clambered into these three hazmat suits, complete with a full hood and gas mask. They wore this strange get-up for the entire helicopter ride back to the USS Hornet, and only took them off when they’d been sealed up in a big silver airstream trailer, the ‘Mobile Quarantine Facility’, for the trip back to Houston. This was all in the name of health and safety, just in case of the extremely remote possibility that Apollo 11 brought back some sort of lunar plague, or something like that.

    And here they now were; the three of them, a doctor, and a technician, all sealed up in a tin can that, to give it credit, was slightly more plush and roomy than Liberty and Columbia had been during the mission, with significantly better food.

    The journey back to Houston came in three parts - first, the USS Hornet sailed for Hawaii. It was during this part of the trip that the President had made good on a promise to visit the crew; they’d spoken to him through a window at the end of the trailer during their first few hours back on Earth.
    This first leg of the journey also found a new experience for John - for the first time in his life, the Naval aviator found himself feeling slightly seasick. It wasn’t at all fun, and he assumed his week in mostly zero-gravity was to blame - ‘still adjusting back to Earth, or something,’ he’d thought to himself, though he’d neglected to mention it to the doctor aboard out of a natural astronaut’s distrust of medical professionals.

    Once the Hornet had made it to Hawaii, the Mobile Quarantine Facility, crew and all, was moved to Hickam Air Force Base, loaded into a cargo plane, and flown out to Texas. They were at Ellington now, John assumed; he didn’t recognize the hangar here offhand, glancing out the window.

    One major benefit of the quarantine trailer over being in space was the sudden availability of news - there was a radio aboard the trailer, and they’d even gotten a couple newspapers in Hawaii. Another one had been delivered this morning, slotted inside the trailer via a small airlock-type thing in the wall. Mike was the one to grab it this time around, and casually tossed it onto the table next to John. “Mail call.” he muttered, still rubbing the sleep from his eyes.

    John looked down to the paper, fully expecting an image of himself, or Gus, or the both of them from the EVA, to be on the front page - it’d been that way in Hawaii, full-page specials about “MAN WALKS ON MOON” that he hadn’t bothered to read just yet. His eyes fell to the page, and immediately spotted “MOON” in the title, and he went to turn to another section, but paused. There wasn’t an image of him or Gus, or the LM, or anything like that; instead, there was a black-and-white depiction of some sort of space probe, all rounded tanks and angular struts, emblazoned with the headline:

    Interlude 5: The Red Planet
  • Small Steps, Giant Leaps - Interlude 5: The Red Planet​



    While the space agencies of the United States and the Soviet Union largely busied themselves with the momentous task of sending crewed flights to the Moon, robotic explorers had long been travelling further. Long before Project Apollo or even Project Gemini left the ground, the Mariner series of space probes had been exploring Earth’s planetary neighbors. The initial missions were launched in pairs to ensure success even in the event of a single launch failure, which turned out to be wise - Mariner 1 and 3 had failed to reach orbit, but their twins carried on. Mariner 2 and 4 became the first spacecraft to successfully fly past Venus and Mars respectively in 1962 and 1965, and Mariner 5 performed a second successful (solo) flyby of Venus in 1967.
    These probes had, while limited in scope, vastly advanced understanding about the environments present on Venus and Mars. Venus was discovered to be a permanently cloud-shrouded world with a hellish “pressure cooker” atmosphere hot enough to melt lead; Mars, meanwhile, appeared to be a dead world, not too unlike the Moon, with images from Mariner 4’s flyby revealing vast fields of craters beneath the red planet's thin, cold atmosphere.

    Mariner 4 was only the beginning of Mars exploration, however. Launched some 5 and 4 months before Apollo 11, and still speeding through the black gulf of space while Gus Grissom took mankind’s first steps on the Moon, the twin Mariner 6 and 7 probes were expected to complete the first successful double mission of the Mariner program, aimed for Mars.
    This expectation became less certain, though, on the 7th of June, 1969, when for just over a day JPL unexpectedly lost contact with Mariner 6. An investigation into the incident had barely begun when contact was once again lost with Mariner 6 on the 10th, and wouldn’t be regained until two days later. Analysis indicated that a failing battery leaking gas from the spacecraft was to blame,[1] but before a fix could be uploaded, Mariner 6 dropped contact for the third and final time on Friday the 13th, with all further attempts to re-establish a link failing - an unexpected spell of bad luck that dashed NASA and JPL’s ambitions for a dual Mars flyby. Less than two months later, Mariner 6 would fly past the red planet, lifeless.
    Scrambling to save the remaining probe of the pair, Mariner 7 was reprogrammed to ensure it would not meet a similar fate should a similar battery leak occur - although, Mariner 7 would later prove to have never been at risk of failure in the first place.

    To make up for the loss of its twin, Mariner 7 was commanded to perform a burn ahead of its flyby to raise its periareion - the point of closest approach to Mars - allowing it to survey more of the Martian surface at the cost of fine detail resolution. This new trajectory would see the probe swoop in over the northern hemisphere of Mars, before reaching periareion over the Martian equator.

    ----

    As Mariner 7 approached its flyby of Mars, the first images seemed promising but not unexpected; a number of large crater-like features stood out from the vague, swirling face of Mars seen by the probe in black-and-white. This was, to-date, pretty much everything that’d been observed in detail on Mars; craters, and more craters.[2]

    Mariner 7 far encounter.jpg

    [Mars from 200,000 miles away, as photographed by Mariner 7. Image credit: NASA]

    Everything changed, though, on August 5th, 1969, when Mariner 7 passed its closest approach to Mars and began sending back more detailed imagery of the surface. Far from the dead, cratered moonscape seen by Mariner 4, Mariner 7’s images of Mars revealed a world far more complex and dynamic.

    The “craters” seen in the north during the far encounter phase were now revealed to be massive mountains - very closely resembling shield volcanoes on Earth - reaching nearly to the edge of Mars’ thin atmosphere. To the south of them near Mars’ equator, Mariner 7 imaged a complex series of grooves and canyons carved into the surface, whose origin could only be either volcanic or, more excitingly, through erosion by flowing liquid, possibly indicating the presence of water on Mars at some point in the planet’s history. Mars, it seemed, had not always been a dead world; but one with a living history to be uncovered.

    ----

    Along with its groundbreaking discoveries, Mariner 7 raised many new questions about Mars, all left unanswered for the future. Of the four “crater” mountain features seen from afar, only 2 were imaged in close detail - leaving the final two, including one thought to be the largest - to be revealed by future robotic explorers. Mars’ enigmatic canyons, too, left more to be discovered; on the edge of Mariner 7’s field of view to the east, there were indications of an even larger valley or basin, leaving geologists to speculate as to the true extent of the canyon system pictured. Did the planet’s bright polar caps hold the key, trapping the water which once carved these canyons? Or were the planet’s mighty volcanoes to blame, scarring the surface as a part of some wider tectonic activity? Only time, and further exploration, would tell.

    Part 6: Lunar Dreams and Lunar Activities
  • Small Steps, Giant Leaps - Part 6: Lunar Dreams and Lunar Activities​



    By the dawn of the new decade, the Apollo Program's explorations of the lunar surface were off to a running start.

    Apollo 11 had successfully proven that putting a man on the Moon and returning him safely to the Earth was possible; the next goal, then, became to land on-target, to allow for planned, directed exploration of scientifically interesting sites. This, then, was the goal of Apollo 12, which launched into the clear blue Florida skies without issue on November 14th, 1969.

    Apollo 12 was, by all accounts, the textbook Apollo mission. The combined stack of CSM Yankee Clipper and LM Intrepid arrived at the Moon on-time and on-target, and Intrepid landed within 600 feet of its target on the lunar surface - the Surveyor 3 probe, launched over 2 years prior.
    The first mission to bring a color television camera to the lunar surface allegedly boosted sales of color TV sets in 1969's 4th quarter by some 15% in the United States. While never remotely coming near Apollo 11’s record-setting 650 million viewers worldwide, Apollo 12’s viewership remained respectable, bolstered in part by the comedic duo of Commander Charles “Pete” Conrad Jr. and Lunar Module Pilot Alan Bean, narrating their activities on the lunar surface. The flag planting during EVA-1 alone is estimated to have been watched by 40 million American households, some 27 million of which were able to view the stars and stripes in full, glorious red, white, and blue against the stark grey lunar surface.[1] In addition, the crew carried with them a timer for their Hasselblad film camera, which they used to take a now-famous image of both astronauts standing next to Surveyor 3 with Intrepid visible in the background.[2]

    ----

    Whereas Apollo 12 went perfectly, Apollo 13 seemed destined to be about as cursed as superstition would imply, given its 'unlucky' number. Originally scheduled for launch in early April of 1970, Apollo 13’s launch was pushed back to May when, during final spacecraft assembly in the Manned Spacecraft Operations Building in late 1969, the Service Module (SM-109) was dropped several feet while being winched off of its delivery flatbed into a vertical position for integration. While the spacecraft component sustained no outward signs of damage, NASA engineering teams chose to partially disassemble the Service Module to verify this. The resultant inspections revealed minor damage to several interior components, and SM-109 was set aside for possible repair and use on a future Apollo mission. In its place, the Service Module originally destined for Apollo 14, already delivered to Cape Kennedy by that point, was swapped in, but the resultant delays still meant that it would not be until May 10, 1970, that Apollo 13 would launch.

    After the incident with the Service Module was resolved, integration, rollout, and the Countdown Demonstration Test all proceeded perfectly, and the crew of Apollo 13 - Commander Neil A. Armstrong, Command Module Pilot Edwin “Buzz” Aldrin Jr., and Lunar Module Pilot Fred W. Haise Jr. - boarded the Command/Service Module Tyche (named for the Greek goddess of luck and fortune) atop their Saturn V the morning of May 10th, and lifted off from Launch Complex 39A. One last major concern came when, 5 minutes and 32 seconds into flight, the S-II second stage’s center engine shut down 2 minutes too early due to pogo oscillation.[3] This wasn’t mission critical, thankfully - the Saturn V’s design allowed for possible engine failure, and the center engine would nominally shut down earlier than the rest anyways; Apollo 13 simply compensated for this early shutdown by burning the remaining 4 engines on the S-II and the S-IVB third stage for longer. After one parking orbit of Earth, the S-IVB was reignited, and Apollo 13 was on its way moonward, bad luck 'curse' seemingly broken.

    May 15th, 1970
    Apollo 13 MET 133 hours, 25 minutes

    “It really is a- a really magnificent sight up here.”

    Cone Crater was, in a word, big. At 1000 feet across and around 250 feet deep, this scar of an ancient impact was the largest of its type thus far visited on mankind’s three voyages so far to the lunar surface. The inner walls were covered with streaks of bright material, pointing down towards the center where the crater floor leveled out, relatively speaking, into an uneven surface of rubble and lunar dust. All around, both within and without, the landscape was scattered with boulders. They littered the crater’s floor, walls, and rim; and beyond the rim, they created a maze-like boulder field of impact ejecta, radiating out onto the slopes.
    And here Commander Neil Armstrong stood, staring down into Cone Crater from its southern rim. There wasn’t much time to admire the view, however - they had a timetable to keep.

    “Okay. Estimated time of departure from Cone is in about 10 minutes, fellas.”

    Lunar Module Pilot Fred Haise responded first, with a quick “Copy that.”

    Time was a constant adversary on the Moon - only so much air and cooling water in a spacesuit, only so long before they needed to rest. Neil and Fred had already spent the better part of their second, nearly 2.5-hour moonwalk simply trying to get here, navigating up the side of Cone’s outer slope through increasingly rocky and confusing terrain. They’d very nearly given up on reaching Cone’s rim when, during one last push, Fred had taken a few steps north past a boulder they’d been sampling, and caught sight of it.

    Neil turned away from Cone Crater for a moment now to see that his Lunar Module Pilot stood some twenty feet back from the crater rim. Far away, back down the slope of Cone, he could just about spot the gold glint of their Lunar Module, Eagle, among the rolling, hummocky lunar terrain of Fra Mauro. It was quite the picture of lunar exploration at work. Ever the photographer, Neil raised his camera.

    “Hey Fredo, hold it right there- This is a good shot, with the LM down in the valley, and you and the boulders.”

    Fred looked up from the pair of tongs he’d been fiddling with, and, seeing the camera, struck a pose, holding the tongs straight down in one hand and shifting to the side, to give the appearance - as best one could in a bulky, dust-darkened spacesuit - of a man casually leaning upon a walking stick. With a laugh at this display, the Commander snapped a picture, before turning back to the rushed work of geological sampling.

    While NASA pushed forward with the first lunar landings of Project Apollo, on the other side of the Iron Curtain, the Soviet program under Mishin’s direction continued slow and steady progress towards their own lunar mission.

    The spectacular failure of the N1 rocket on its first flight emphasized the need for further development. Rodina 1 had provided a much-needed boost in funding and support, and Luna 15’s success in returning lunar samples only served to bolster this. Mishin and his program now had the political capital needed to afford a step back, so that they could truly begin the work required to turn the Soviet Union’s lunar dreams into a reality.

    In support of this, Mishin ordered the construction of a massive test stand at Baikonur that would enable test firings of the N1 booster components - this way, if something went wrong during a test, they wouldn’t have to contend with their vehicle falling out of the sky and exploding on impact, and subsequently having to pick through the charred wreckage to determine what happened.
    Two of the N1 vehicles being built would also be sacrificed to this cause - Booster 4L had already been partially disassembled after cracks had developed in its Blok A LOX tank,[4] so its components would be utilized in testing and inspection. In addition, Booster 5L was broken up so that its stages could be individually test-fired.[5]

    Although this expanded testing effort in support of the N1-L3 complex would push the potential date of a Soviet lunar landing well into 1971, Mishin - and, importantly, his allies among the Politburo - felt that the prestige of a manned Soviet lunar landing was well worth the delay, and much more desirable than a rushed, costly, and embarrassing failure.

    Interlude 6: Explorers of the Frontier
  • Small Steps, Giant Leaps - Interlude 6: Explorers of the Frontier


    By the late 1960s, scientists at NASA’s Jet Propulsion Laboratory - and their counterparts in the Soviet Union - had realized the potential of gravity assists in exploring the outer worlds of the Solar System. A once-in-a-century alignment of the planets, first discovered by JPL’s Gary Flandro in 1964, could allow a single spacecraft to visit three or even four of the outer planets in one mission, using the gravity of each successive flyby to slingshot it to the next. This so-called “Planetary Grand Tour” became a top priority for unmanned space exploration going forward.

    Jet Propulsion Laboratory's initial concept for a Grand Tour mission, called TOPS (Thermoelectric Outer Planets Spacecraft), would have seen four spacecraft, launched in pairs - two to Jupiter, Saturn, and Pluto launched in 1977, and two to Jupiter, Uranus, and Neptune in 1979. This was quickly canceled, however, due in part to the expense of launching four spacecraft of a brand-new design.
    Replacing TOPS was Mariner Jupiter-Saturn, a two-spacecraft proposal based on the existing Mariner spacecraft bus. While advertised as a mission to Jupiter and Saturn only, JPL designed these probes with the intention of performing a full Grand Tour, should funding allow.

    By mid-1972, the program had changed yet again, following a (relative) increase in NASA’s planetary exploration budget. This third and final iteration, entitled “Mariner Grand Tour”, would utilize three spacecraft of a similar design to the MJS ‘77 proposal, and between them would perform a full Grand Tour of all five outer planets - Jupiter, Saturn, Uranus, Neptune, and Pluto.

    ----

    Similar to the United States, Soviet plans for the Grand Tour were initially very ambitious. The Lavochkin design bureau pitched a fleet of four or five spacecraft, equipped with multiple small sub-probes to explore the gas giants’ atmospheres or their moons from close-up.

    Although technically feasible, the concept was a political and financial non-starter at first. It was only in the late 1960s-early 1970s rush of funding surrounding the Rodina moonshot that the Soviet Grand Tour would have its day, albeit in a truncated form; the mission approved to fly consisted solely of two stripped-down spacecraft derived from the existing Venera probes, with radioisotope generators replacing their solar panels.

    ----

    Dreams of a Grand Tour would have to wait, however, as the launch window wasn’t until 1977. In the meantime, however, both NASA and the Soviets made tremendous progress in planetary exploration elsewhere.

    Over the course of the late 1960s, Soviet Venera probes penetrated deeper and deeper into the dense, cloudy atmosphere of Venus; each, however, failed before reaching the ground, succumbing to the immense heat and pressure. Soviet engineers learned from these failures, and continued to reinforce their probes with each new mission. Finally, on December 15th, 1970, Venera 7 achieved the seemingly-impossible: the spacecraft made a successful soft landing on the Venusian surface and transmitted data for 23 minutes before failing. With probes able to survive Venus, Soviet engineers prepared for even more ambitious missions to Earth’s hellish planetary neighbor; probes which could last longer on the surface and even record images and audio.

    1971, meanwhile, was a busy year for Mars, with a flotilla of four robotic spacecraft departing for the Red Planet in a race to become the first spacecraft to orbit another world. This race was ultimately won by the twin Mariner 8 and Mariner 9 spacecraft, entering Mars orbit on November 12th and 14th of 1971 respectively - mere weeks before the Soviet Mars 2 and 3 would do so.
    Initial observations by the Mariners revealed that the entire Martian surface was covered by a thick dust storm - a disappointment, but not unexpected. It took until early January of 1972 for the dust to gradually settle, revealing first the massive mountains first spotted by Mariner 7, and then slowly, the rest of Mars, to the waiting orbiters.

    Despite losing the race to arrive first, Mars 2 and Mars 3 were somewhat more ambitious in their mission than the Mariners. Each probe carried a small lander, designed to last for a few days on the Martian surface before their batteries would be depleted. Aboard each of these landers was a tiny, ski-propelled rover called Prop-M, connected to the main lander via a cable.

    Mars 2’s lander malfunctioned due to a too-steep descent, crash-landing when its parachute failed to deploy. Mars 3 was somewhat more successful, diving into the atmosphere and soft-landing on Mars on December 2nd, 1971. The lander operated for barely 3 minutes upon landing, enough time to scan and transmit a partial, black-and-white image of the Martian surface before succumbing to the raging, planet-wide storm which it had not been designed to survive.

    ----

    While the Soviets found varying degrees of success at Mars and Venus, NASA looked elsewhere - inward to the innermost planet, and out to the giants.

    Originally conceptualized as “Mariner-Mercury,” the Mariner 10 probe launched on an Atlas-Centaur booster towards Venus in 1973, and flew by that planet - in the first ever use of the gravity assist technique to lower its perihelion - before proceeding onward to Mercury in 1974. Mariner 10's first flyby trajectory would put it on a resonant orbit with the solar system’s innermost planet, allowing it to fly past Mercury two additional times before it exhausted its attitude control fuel and lost contact with Earth. Mariner 10 revealed Mercury as a rough, cratered world not dissimilar to the Moon, with an extremely tenuous atmosphere and an active magnetic field. It disproved once and for all the theory that Mercury was tidally locked to the Sun, and in the end mapped over 40% of the planet’s surface during its three flybys in 1974.

    ----

    Pioneer 10 and Pioneer 11 - originally “Pioneer F” and “Pioneer G” - launched atop Atlas-Centaurs in 1972 and 1973 respectively, both targeted at Jupiter. Their goal, together, was to pave the way for the coming ‘Grand Tour’ probes, passing safely through the asteroid belt and exploring the environment of the largest planet. Pioneer 10 flew by Jupiter in 1973 followed a year later by Pioneer 11. The probes revealed Jupiter’s magnetic field to be the strongest in the solar system, barring the Sun, probed belts of trapped radiation around the planet, similar to the Earth’s Van Allen Belts but much more powerful, and photographed the swirling storms of the giant planet up close. Neither spacecraft made a close approach to any of the Jovian moons, and their cameras returned images only of fuzzy blobs, only slightly better than the best Earth-based telescopic views.

    Pioneer 10’s planetary story ended after its flyby, with the spacecraft flung out of the solar system by Jupiter’s immense gravity. With its twin’s prior success at Jupiter, Pioneer 11 was re-targeted in May of 1974, flying over Jupiter’s pole in a gravity assist maneuver to enable a flyby of Saturn in 1979 before it, too, would leave the solar system for interstellar space.

    Part 7: The Shepard Shuffle
  • Small Steps, Giant Leaps - Part 7: The Shepard Shuffle​



    October 5, 1970
    Apollo 14 MET 114 hours

    With little more than a kick from his right boot, the Commander slipped off the last rung of the ladder and onto the LM footpad. Turning, he stepped one foot down onto the surface, and reached up to raise his sun visor - to gaze out over a new world with his own eyes, scanning the horizon unfiltered by the protective layer of gold for just a moment. He took a couple tentative steps further onto the Moon, surveying the environment with an almost childlike wonder.

    Out to the west, the surface seemed almost without texture, save for the rolling black horizon. Boulders and craters alike were washed out by the sun, painting a flat tableau of muted greys with a hardly-perceptible warm undertone, like a strange, ashen beach sand.

    To the east, the low sun cast long shadows across the pockmarked lunar terrain, every single rock thrown into sharp relief across the crater-dominated landscape. Everything seemed almost sandblasted smooth by untold eons of micrometeoroids, hardly a rough edge in sight. The highland hills he knew by heart from maps, out on the edge of the mare, peeked up over the close horizon, half in darkness. It was magnificent, in an eerie, unreal sort of way.

    “Worth the wait, Jim?”

    Lunar Module Pilot Ed White’s words stirred Jim Lovell from his moment of silent observation. He turned back towards Aquarius, squinting as the bright, unfiltered sun hit his eyes for a moment before pulling his visor back down.

    James Arthur Lovell Jr. had flown three prior missions to space - Gemini 7, Gemini 12, and Apollo 10 - before this one. He stood here now, the first man to fly to the Moon twice, and the 7th man to walk on its surface. If this wasn’t the pinnacle of his 8 year career as an astronaut, he didn’t know what was.

    "Every minute, Ed. Every minute."

    Apollo 14.jpg

    [Apollo 14 Commander James A. Lovell Jr. deploys the American flag on the lunar surface. Note the Navy decal on the visor’s red “Commander” stripe - the only such spacesuit customization of any Apollo mission. October 5th, 1970. Image Credit: NASA]



    Apollo 15’s crew selection sits as something of a historical peculiarity, upon first glance.

    Since Apollo 9, and before then loosely dating back through Gemini and Mercury, there had more or less been a pattern to how spaceflight crews were selected: a crew would first serve as backups for a mission, and then, three missions later, they’d become the prime crew. This “back one, skip two, fly one” pattern held firm through Apollos 12, 13, and 14 - Pete Conrad and his crew had backed up Apollo 9, and thus flew on Apollo 12; Neil Armstrong’s crew had backed up 10, and flown 13; Jim Lovell’s crew had backed up 11, and flown 14.

    Given this relatively regular pattern (the early crew shuffles of 7 and 8 as Apollo found its feet notwithstanding), one would assume that the mission of Apollo 15 - the final H-class "walking" lunar landing - would be given to the Apollo 12 backup crew of Commander David Scott, Command Module Pilot Alfred Worden, and Lunar Module Pilot James Irwin. History tells us, however, that this crew was to fly one mission later, on Apollo 16.

    What caused this bump in the Apollo rotation, throwing off the pattern? There is one definitive answer to that question: Alan Bartlett Shepard Jr., first American in space and, from 1963 onwards, Chief of the Astronaut Office.

    ----

    To someone watching NASA goings-on in the early days, Al Shepard would’ve seemed like a shoe-in for Project Gemini’s more advanced orbital flights, and eventually for Apollo’s missions to the Moon. In fact, Al Shepard was originally slated to fly Gemini 3, the first crewed flight of the new spacecraft. This ambitious path forward, however, came to a screeching halt in late 1963, when seemingly out of nowhere, Shepard began experiencing dizziness, nausea, and severe tinnitus in his left ear. After attempting to keep this secret for some time, Shepard eventually informed NASA management and doctors, and was diagnosed with Ménière's disease, an inner ear disorder that severely affects balance and hearing.

    This, in effect, ended Al Shepard’s potential flight career as an astronaut, with only one 15-minute suborbital hop to his name. He was pulled off of Gemini 3 in favor of Gus Grissom, and his flight status was revoked indefinitely.

    The story from there is well-known: Al Shepard became Chief of the Astronaut Office in November of 1963, and spent the next 5 years as Chief Astronaut, until in 1968 otologist Dr. William House developed a cure for Ménière's, which was administered successfully to Shepard in mid-1969.[1]

    Al Shepard’s flight status was restored in June of 1969, and at the time, the next lunar landing yet to be crewed was the coming 1970 flight of Apollo 14. Shepard, still having some influence over crew selection as Chief Astronaut, agreed with Director of Flight Operations Deke Slayton (a fellow grounded Mercury astronaut himself, due to a heart condition) to assign himself to Apollo 14 as Commander. Initially, Shepard asked Jim McDivitt - former Commander of the Apollo 9 test flight - to fly as his Lunar Module Pilot, but McDivitt turned the offer down, believing Shepard too inexperienced to command a lunar landing.[2] In his place, rookie astronaut Edgar Mitchell was assigned as LMP for Shepard’s crew, having previously served as backup LMP for Apollo 7. Shepard’s Command Module Pilot would be another rookie, Stuart Roosa.

    NASA management, however, agreed more with McDivitt than they did with Slayton and Shepard; they were of the opinion that Shepard needed more time to train, and thus assigned his crew to Apollo 15, rather than 14. This would maintain the crew rotation through Lovell’s crew, but thereafter caused a “bump” in the lineup - backup crews from that of Apollo 12 onwards could expect to fly to the Moon not 3 missions later, but 4. This held mostly true through the program's end, with the backup crews of Apollo 12-15 flying on Apollo 16-19; the matter of Apollo 16’s backup crew and Apollo 20 is already well-documented elsewhere.

    In Shepard’s absence for Apollo 15’s training and flight, astronaut Tom Stafford - having previously acted as backup Commander for Apollo 8 - would take his place as Chief of the Astronaut Office. This would be a temporary arrangement, with Shepard returning to the role and Stafford returning to his own duties, and flight status, upon Apollo 15’s return.



    As a mission, the February 1971 flight of Apollo 15 is remarkable for a few things: It was the final “walking” H-class mission, utilizing a Modular Equipment Transporter similar to Apollo 14 for surface operations[3]; It had the oldest Commander of any Apollo, Shepard being 47 during the mission; it was by some accounts the first landing in proper lunar highland terrain (not counting Apollo 13’s landing at Fra Mauro, which is debated to be either “true” highlands or a distinct formation); it visited and sampled the edge of the largest, deepest, and brightest crater of any Apollo H-class mission (Censorinus Crater, a whopping 3.8km wide, one of the brightest surface features on the lunar nearside); and it was the first mission not to quarantine the crew upon their return to Earth.

    Censorinus.jpg

    [Apollo 15’s landing site, the bright ray crater Censorinus, as photographed from lunar orbit by a later Apollo mission. Image credit: NASA]

    What Apollo 15 is the most famous for, perhaps, is golf. Shepard, an avid golfer, brought along with him two golf balls and a six iron golf club head, modified to fit on the end of the contingency sample tool, and shot a few golf swings on the lunar surface (one-handed, due to the spacesuit’s stiffness) live on television near the end of EVA-2. This stunt, while unsanctioned by NASA, was received well, and today Al Shepard is perhaps just as famous for being the first American in space as he is for golfing on the Moon.



    As NASA closed out the first phase of its lunar explorations and ramped up for the even more ambitious J-missions to come - with uprated hardware, a motorized Lunar Roving Vehicle, and stays of up to 3 days on the lunar surface, among other things - the overall program structure of Project Apollo fell properly into place by about mid-1970.

    With Skylab on track for launch in early 1973, that year was set aside in the planning; Apollo lunar missions would proceed at a pace of 2 per year, through Apollo 18 in late 1972, before pausing to allow NASA to focus solely on Skylab operations for all of 1973, including 3 crew missions to the station. Apollo 19 and 20, the final two lunar landings of the program, would fly in 1974. Project Apollo was set at least through the middle of the new decade, with prospects for a 4th mission to Skylab and at least one other Earth-orbit Apollo flight of some kind following the lunar program. By the time it was done, NASA's plans for the future, in the late 70s and beyond, would already be well underway.

    ----

    Even as eyes turned to the future of NASA in a post-Apollo world, much of the immediate focus remained, for the time being, on the Moon - bolstered in 1971 by a new sense of competition, as the USSR pushed ever closer to their own ultimate lunar goals...

    Interlude 7: The Space Transportation System
  • Small Steps, Giant Leaps - Interlude 7: The Space Transportation System​



    In the late 1960s, NASA developed a plan for the future based on the assumption that funding would continue at or above Apollo funding levels. This outline for the future was known internally to NASA as the “Integrated Program Plan”, or alternatively the “Space Transportation System”, and was presented to President Kennedy by the Space Task Group as early as September of 1969.

    The IPP/STS envisioned a massive network of space infrastructure, with chemical and nuclear “space tugs”, space station modules boosted to orbit by a reusable "Space Shuttle", and modified Saturn Vs, all in service of extensive lunar and even Martian exploration. The plan was ambitious, broad-reaching, technologically feasible, and completely politically impossible.

    NASA's budget and overall political support fell greatly after the Apollo peak, making a costly endeavor like the IPP/STS a non-starter. Over a series of meetings, much like the Apollo Applications Program before it, the proposal was whittled down to the two elements that could most easily be used as the starting point for future space endeavors: the Space Shuttle, and space stations for it to support.

    The grand "Space Operations Complex" station that NASA had envisioned would be pushed back to the mid-1980s, at least, in order to not impose an enormous funding burden, and to allow key technologies to mature; in the meantime, NASA would have two interim space stations through the 1970s: Skylab itself, still on track for a 1973 launch, and a successor station built around Skylab's backup.

    Skylab - predating the new Program Plan, but very much a part of its goals - would serve the key function of giving NASA experience with space stations, "wet workshop" outfitting, and long-duration crewed spaceflight, while its successor - provisionally named "Starlab" - would be used in tandem with the Space Shuttle to practice modular assembly techniques, continuous occupation with crew rotations, and microgravity science.

    NASA’s extensively revised Program Plan was approved by President Kennedy in early 1972, with expectations of crewed Space Shuttle missions by 1977, and the launch of Starlab by 1978.

    The Space Shuttle quickly evolved, under tight budget pressures and ever-shifting requirements from NASA, as well as various interested government agencies including the Department of Defense. The end result would be a partially reusable system, with a delta-winged “Orbiter” spaceplane launched into orbit by an expendable rocket stack.

    The Space Shuttle was designed for numerous roles: servicing America’s space stations, constructing the SOC space station, launching commercial and government payloads, and repairing satellites in orbit. As a consequence, Shuttle development costs quickly spiraled, pushing the timeline for any flights of the new system back from initial predictions.

  • Small Steps, Giant Leaps - Part 8A: Долгий путь (Long is the Way)​



    The successful 1969 circumlunar crewed flight of Rodina 1 gave the Soviet space program a well-deserved boost in morale and, more importantly, funding and political support. Much of the funding and political good will was directed back towards the Rodina/N1-L3 complex, thanks largely in part to the machinations of N1 program lead Vasily Mishin; the Union may have lost the race to the moon, but they could at least achieve a graceful second place.

    To achieve this goal, an extensive test campaign was carried out over the course of late 1969 through all of 1970, disassembling N1 boosters 4L and 5L for inspection, and static-firing all of the N1’s stages (taken primarily from booster 5L) individually. Through the course of this, a slew of issues were diagnosed and treated, particularly with the Blok A stage’s KORD control system and engine plumbing. To counteract the guidance issues encountered during the first test launch, numerous changes were made to the KORD system’s programming logic.

    By April of 1971, the second operational N1 booster - designated 6L - was fully assembled in a flight-ready configuration, topped with a partially boilerplate Soyuz LOK (with a functional Descent Module and engines, but a boilerplate Orbital Module) and a boilerplate LK, and rolled out to Site 110/38 for launch. The mission, after verifying the N1’s ability as a launch vehicle, would be to send this simulated lunar stack all the way to lunar orbit, where cameras aboard the LOK would be used to photograph potential crewed landing sites.[1]

    ----

    N1 Booster 6L lifted off from Site 110/38 for the second test flight of the N1-L3 complex on April 18th, 1971. Things began to fall apart distressingly quickly, so it seemed, with two engine failures in quick succession at approximately 37 seconds into flight. The KORD control system dutifully shut down the opposing engines of each pair, leaving 6L’s Blok A stage with 26 engines firing - the minimum amount for nominal performance. Increasingly pressing issues in the latter part of the first stage’s flight, including gimbal failures on a handful of the remaining engines, a third Blok A engine failure at 59 seconds, and a liquid oxygen leak from Blok A’s LOX tank, meant that N1 6L would be unable to reach its planned lunar trajectory; however, this did not mean the end of the mission.

    The N1 achieved its first successful staging - not counting the launch escape system on the previous flight - with Blok A's remaining engines cleanly shutting down and Blok B igniting its own engines without incident some 130 seconds into flight.

    Blok B fared marginally better than Blok A, losing one opposing pair of NK-15V engines near the end of its climb. Blok A’s underperformance, however, meant that the Blok V third stage would not be enough. Flight controllers were thus forced to use the Blok G stage - intended for trans-lunar injection - to push the stack into Earth orbit.

    The simulated lunar stack reached Earth orbit successfully - albeit one stage shorter than a nominal flight - where it was able to carry out at least part of its mission. Using the Blok D lunar orbit stage and the Soyuz’s engines, the stack was accelerated into a high-apogee orbit, to simulate a high-speed lunar re-entry on return. The LOK’s Descent Module returned to Earth successfully on the next pass some 7 hours later, splashing down in the secondary landing zone in the Indian Ocean.

    ----

    Retroactively designated Rodina 2, the second N1 launch - and by extension the very existence of the massive N1 booster - was announced to the world by Soviet news outlets on April 19th, 1971. The failed lunar flyby was, of course, covered up, with Rodina 2 passed off as a successful Earth orbit test of the Soviet lunar architecture.

    Despite the myriad issues with the N1’s second launch, Rodina 2 was a marked improvement from the disastrous first test flight - it had worked, somehow, and the mood among Soviet space personnel was one of cautious optimism. The remaining issues with the N1 were known, and could be fixed; the Moon, it seemed, was finally within reach.



    Following the launch of Rodina 2, all of the components of the N1-L3 lunar complex had individually been tested in flight in some capacity. Although the Blok A stage had encountered a number of serious issues, the near-flawless performance of the upper stages had allowed 6L to limp to orbit and carry out a truncated test mission which returned good data. With the Kuznetsov design bureau's vigorous assurances that the next batch of NK-15 engines would not encounter similar issues, preparations for the final test flight and the first crewed flight, a "dress rehearsal" in lunar orbit, began. Throughout the high summer months of 1971, N1-L3 components arrived at Baikonur for assembly and integration as N1 Booster 7L.

    If all went well, 7L would propel the first Soviet cosmonauts to lunar orbit before the end of 1971. Selected to command the mission was Yevgeny Khrunov, veteran of the joint Soyuz 5/Soyuz 4 mission, with Vladislav Volkov, who previously flew on Soyuz 7, as his LOK Pilot and Flight Engineer.[2] The mission was to be superficially similar to the American Apollo 10, with Khrunov taking the LK lander down to only a dozen kilometers above the lunar surface before simulating an abort and making an emergency disconnect from the Blok D crasher stage. If necessary in the event of a failure, Volkov could pilot the LOK down to the lower orbit to meet the LK.

    As was common for any crewed Soviet spaceflight, the crew was to decide a callsign for their mission to be used in communications. Unlike all previous Soviet spaceflights, however, Rodina 3 would be the first mission comprising two spacecraft in a single launch, rather than a joint mission like that of Soyuz 4/5 or Soyuz 6/7. This led the crew to select two callsigns, one for each individual spacecraft. When operating independently in lunar orbit, the LOK would be referred to as Buran (“Blizzard”) - the same as Volkov’s spacecraft on Soyuz 7 - and the LK would be referred to as Zenit (“Zenith”).

    ----

    Rodina 3 lifted off into the clear morning sky on August 29th, 1971. After an early initial scare, where an NK-15 pair shutdown at 45 seconds threatened a repeat of Rodina 2, the launch of Rodina 3 proceeded within otherwise nominal parameters. Blok B and Blok V pushed the stack into a circular Earth orbit, and after one revolution spent verifying systems, Rodina 3’s Blok G stage ignited and sent Khrunov and Volkov moonward. The mission was officially announced by Soviet media not long after, following the established precedent from Rodina 1’s circumlunar flight of publicly announcing lunar missions once en-route to the Moon.

    The first full-up test of the L3 complex proceeded nearly as smoothly as its American counterpart. Unlike the cramped, single-module arrangement of Rodina 1’s stripped-down L1 spacecraft, Rodina 3’s crew had a comparatively spacious arrangement between their Descent and Orbital Modules. Whereas Shatalov and Yeliseyev had shared Rodina 1’s circumlunar flight with two bulky “Yastreb B” launch/entry spacesuits[3] (the first mission to use such an arrangement since Voskhod 2), Rodina 3 fell back to the now-familiar arrangement of Soyuz, with the mission’s spacesuits - both new models, Orlan (“Sea Eagle”) for the LOK Pilot and Krechet (“Gyrfalcon”) for the Commander[4] - stored in the Orbital Module and only worn during EVA operations, and the crew spending the rest of the mission aboard the LOK in basic flight jumpsuits.

    The LK proved itself to be as reliable as its American counterpart in a series of trials that validated its systems and built on earlier automated tests in Earth orbit. Onboard instruments were used to photograph future planned landing sites, and Khrunov piloted Zenit to within a dozen kilometers of the Oceanus Procellarum - the landing site set for the eventual landing attempt - before ascending back to a rendezvous with Buran.

    Of historical note is the mission’s timing with respect to its American counterpart - Apollo 16 launched on August 24th, 5 days before Rodina 3; Rodina subsequently launched while Apollo astronauts David Scott and James Irwin were closing out their stay of over 2 days on the lunar surface at Descartes. Apollo 16 remained in lunar orbit until September 1st, the same day Rodina 3 arrived, and for a brief 6 hours the two missions shared lunar orbit. This would mark the second time in history that two crewed missions were in the vicinity of the Moon at once, and the first time that two crewed missions from different nations orbited the Moon at the same time.

    One of the mission’s most important objectives - EVA transfer, needed both to board the LK and to return to the LOK after a landing, due to the lack of any internal hatch between the two - went flawlessly. Commander Khrunov performed the first EVA in lunar orbit on September 2nd, transferring across from Buran’s Orbital Module into Zenit, still partially shrouded in a fairing between the LOK and Blok G. This was notably not the first deep-space EVA, as Apollo 16 Command Module Pilot Alfred Worden had performed an EVA just hours before en route back to Earth, to retrieve film and scientific data from the Apollo spacecraft’s Service Module.[5]

    Rodina 3 returned to Earth on September 6th, 1971, touching down on the plains of the Kazakh SSR. The mission's successful one-week stress test of the L3 lunar complex gave the final go-ahead needed for the next mission to attempt a full lunar landing mission. Preparations began immediately.
    If all went well, before 1972 was out, the first cosmonaut would walk on the Moon.

    January 22nd, 1972
    Rodina 4 T-02:55:00

    The old bus clattered along the unpaved road. Visible in glimpses through the drifting snow, Site 110 loomed, illuminated ghostly pale by bright floodlights. At the center of it all, a single, bright white spire- their destination, and their ride.

    Eventually, the rattle of the vehicle’s ill-fitting windows quieted, as it came to a stop at a predetermined point. The two cosmonauts were ushered out, shrouded in heavy coats over their flight suits. Valeri clutched the fur-lined hood closer, shrouding himself against the wind.

    The ritual was performed quietly, almost solemnly, the sounds of the whistling wind and of the fat, heavy snowflakes impacting the gathered snow on the ground around them the only noise to break the silence. Alexei went first, of course, and Valeri respectfully looked away; on his turn, the pilot couldn’t help but feel as if someone were peering over his shoulder, even with Alexei facing away- the spectral form of their booster, perhaps, looked on as he completed one of the final rituals before setting off. It was the last in a complex chain, all linked back to the first to walk this path- Yuri Gagarin. They’d visited his grave in the Kremlin wall, planted a tree in a grove near Baikonur, even seen his office - still preserved, as it had been since his death in 1968. And now, as Gagarin had done before Vostok, they too had pissed on the back right tire of their transfer bus. Having no desire to remain standing around in a snowstorm, the crew of Rodina 4 quickly climbed back aboard the bus, which continued its rough trek onwards.

    ----

    T-02:10:00

    There it stood- like a gleaming white marble cathedral, all Gothic angles and intricate trusswork, the mighty N1 booster towered into the clouds, seeming from this low vantage entirely unphased by the weather. Valeri took a passing glance at the many clustered engines, poking out from the first stage’s wide base and just visible over the lip of the pad’s recessed middle - those 30 engines were the key. Without their cooperation, the mission would be getting nowhere fast.

    ----

    The cosmonauts climbed up into the elevator with a collection of ground crew, savoring what would be their last steps on bare soil for some time. With a creak and a snap, the doors slammed shut and the motor pulled them upwards.
    The rocket rolled past the windows, painted pure white. On closer inspection, the imposing machine appeared much less of a solid monolith. It seemed almost absurd that they would entrust their lives to this contraption, so obviously fragile and delicate, rivets and welds tracing across its skin, dents and wrinkles visible in the metalwork under the gloss of white. This was the truth of all manned spaceflight, really; grand visions of mighty and powerful rockets, held together in actuality by very careful engineering and quite a bit of luck. Valeri said nothing - they were in this now, for better or worse.

    ----

    T-01:55:00

    Grinning technicians helped them through the hatch and into the LOK, shaking their hands as they went. Valeri went first, climbing down a ladder past supply bags and their two stowed spacesuits in the Orbital Module before dropping into the Descent Module and settling into his couch. After Alexei joined him, the technicians sealed up the hatches - first that between the Orbital Module and the Descent Module, leaving the crew isolated, and then - now out of sight, but still able to be heard - the Orbital Module’s main hatch. Supply bags were scattered around the cramped interior of the Descent Module, holding everything they would need for the one-week mission.

    With a few clicks, the two men fastened their straps. Now all they had to do was wait.

    ----

    T-00:43:00

    "Rodina, we are beginning propellant loading. The Launch Escape System is now armed."
    "Understood, Control. Everything is looking good from here."

    The N1 groaned and hissed as kerosene and oxygen snaked in from feed lines on the launch tower. It almost seemed to come alive, straining to be released from the chains of gravity, to pierce the snowy sky above and climb into the heavens.

    ----

    T-0:01:00

    "Rodina, the situation is nominal at 1 minute. Everyone in the control bunker is very proud to be working with you, and we are wishing you good luck and success."

    "Thank you, Control. We hope to not let you down!"

    ----

    The seconds ticked down. Over the comm, a launch controller’s voice counted in sequence.

    At 6 seconds, the booster’s 30 engines flared to life far below.

    “5.”
    “4.”


    Valeri felt a hand clap on his shoulder. Over the growing rumble of the engines, Alexei looked over to him with a twinkle in his eye. The two exchanged a look, before affixing their eyes back on their respective consoles.


    “3.”
    “2.”
    “1.”

    With a thunderous, many-throated roar, the N1 lifted off from the pad and began its upward climb. Feeling the kick of slow, building acceleration in his back, Valeri found himself smiling, and then laughing.

    As the rocket pushed upwards away from Site 110, Valeri Nikolaevich Kubasov shouted with elation- one last connection to the start of it all, to tie it all together.

    “Poyekhali!”

    January 26th, 1972
    Rodina 4 MET 4 days, 6 hours

    The hatch was open. Outside, the battered grey surface of the Moon slid past below an infinite expanse of black.

    The time had come.

    ----

    The trip to the Moon had been, despite the extraordinary nature of the mission as a whole, relatively uneventful. Launch had been within normal parameters, with only a single engine failure out of 30, very late into the first stage burn. After trans-lunar injection, it was simply a multi-day coast out to the Moon, keeping the spacecraft in order all the while. An issue with the waste disposal controls, a faulty reading from a fuel cell at one point in day 2 - the same sorts of little things Rodina 1 and 3 had experienced. Alexei and Valeri had been sure to pack something to read in the downtime.

    Arrival in lunar orbit had been similarly nominal, repeating Rodina 3 to the letter. They’d spent a sleep period in orbit, and now, having awoken for the day and gone about final preparations, it was time for Commander Leonov to perform his EVA transfer before the two spacecraft were to separate. The two cosmonauts had entered the Orbital Module, and helped one another to don their respective spacesuits. They looked a strangely mis-matched pair; Valeri, in his Orlan spacesuit meant for orbit, all khaki tans and off-whites with blue stripes; and Alexei, in his Krechet lunar suit, done up in white with red accents- white for its thermal reflectivity, and red, of course, for the USSR, her flag emblazoned proudly on both the suit’s arm and the middle of the integrated backpack/entry hatch.

    ----

    For the second time in his life, Alexei Leonov found himself staring out the hatch of a spacecraft at the infinite, deadly void of space.

    He couldn’t help but think back to the first time - the first of any time, on Voskhod 2. He’d bumbled out into the unknown, leaving the cramped spacecraft’s flimsy inflatable airlock and floating aimlessly for some 12 minutes above the Earth. It’d been beautiful; life-changing, really- but it’d also come close to being life-ending. A poorly-designed EVA suit, overpressurized to the point of ballooning outward; a risky maneuver, bleeding off air to dangerous levels just to be able to re-enter the airlock. Not to mention the hatch issues, the bungled re-entry, the night spent hiding out in the capsule in the freezing taiga during wolf mating season with pistol close at hand-

    “Commander? Alexei?”

    Leonov snapped out of his reverie at once. It was 1972, not 1965; spacewalks were now a well-practiced part of space missions, with more than half a decade of refinement and numerous improvements in spacesuit design. He wasn’t even the first person to perform this very maneuver - Yevgeny Khrunov had done it on the test flight last year.

    Carefully, Alexei moved to exit the hatch. The Krechet lunar suit was quite comfortable compared to his last EVA experience, and significantly more maneuverable in the limbs- and a hard torso section, he hoped, would stop any sort of ballooning. Head-first, the Commander climbed out of the Soyuz and proceeded slowly, methodically down the side of the craft, moving and re-attaching his safety tether as he went. Mounted on a point near the bottom of the Descent Module, a long, telescoping boom stretched down towards his ultimate goal - the LK, hidden away beneath a protective black fairing below the Soyuz.

    Reaching the end of the boom and affixing himself to a well-placed handhold, Leonov wasted no time in his next task. Pulling aside a panel in the fairing and flinging it off into the void, Alexei got the first proper look at his lunar craft- the area immediately surrounding the hatch, at least. White-painted structural elements, silvery-white thermal blanketing- an elegant design, one he looked forward to seeing in full on the lunar surface.

    After climbing aboard his lander and securing the hatch, Commander Leonov spent the next hour powering up the little spacecraft, repressurizing the cabin, and verifying all its systems were functioning ahead of separation. Over the far side, the comm crackled to life as his LOK Pilot’s voice came to him from hardly a few meters away back aboard the Soyuz.

    Yantar to Rubin, how do you read?”

    “I am reading you nominally, Yantar.”

    As with Rodina 3, Rodina 4 had chosen two separate callsigns for their individual spacecraft, for use during lunar operations. Alexei elected to call his lander Rubin (“Ruby”) - the callsign Vladimir Komarov had used for his spacecraft on the ill-fated Soyuz 1 - as a tribute to a fallen comrade. Georgy Dobrovolsky, the mission’s backup LOK Pilot, suggested Yantar (“Amber”) for the LOK, after another precious gem.

    And so here Alexei Leonov now sat aboard Rubin, preparing to leave Yantar behind for the time being.

    QutVjyg.png

    Rodina 4 MET 4 days, 9 hours

    Landing on the Moon was, all at once, terrifying and mundane. For much of the descent, the cosmonaut was there simply to verify that the computer was working correctly and make minor adjustments. The Blok D upper stage performed most of the initial burn to slow the LK down to a landing trajectory before separation; from there, Rubin’s main engine slowed the vehicle to a hover at around 110 meters above the surface.

    It was only now, hovering above the Moon in this split-second before he either had to land or abort, that Alexei Leonov realized just how dangerous this all truly was.

    He was facing down a rough, unknown landscape. A sharp-edged crater maybe 50 meters in diameter ahead and to his left, in the direction of the lander’s current target site; across the surface, scattered boulders and rubble seeming to spray outwards from it in all directions. Rubin didn’t have the fuel to fly over and look for safer ground, like the American Apollos could; the best option Alexei could see was to pull back away from the crater, and land more or less directly below where he currently hovered, on the outer edges of the ejecta blanket. It was that, or abort.

    Taking in all this information in a short moment, Leonov reacted with practiced quickness from months of training- he grabbed the control stick, pitching the little lander back to align with the ground below. His field of view out his round porthole window pitched with it, like a ship on a stormy sea; first up, and then back down, revealing the spot below that he was now descending towards at a slow, but increasingly more urgent, pace. The surface there was relatively clear, save for a few small rocks that he could easily avoid. There was a flat area in the middle of it all, right where he’d hoped- this was it.

    “Control, I am in terminal descent. I have a landing site.”

    Rubin’s engine throttled up to slow the terminal descent, turning the gentle flow of dust across the surface into a streaming blizzard of ashen grey, radiating out from under the lander and obscuring the surface just as he’d had gotten his first good look.

    Alexei didn’t feel contact with the lunar surface, but he sure as hell felt what came next - The whole vehicle jolted as, automatically, the main engine cut and four small solid rocket motors mounted on the base of the lander fired to ensure that Rubin was planted firmly on the ground and wouldn’t tip over.

    The cosmonaut exhaled- he hadn’t realized, but he’d been unconsciously holding his breath in anticipation of touchdown.

    “Control, Rubin. I have landed successfully.”

    Then, everything was silent and still. The vibrations of the engine through the body of the lander were gone; Alexei was acutely aware of how heavy his spacesuit felt, even in the low gravity, after 4 days in space. There was no time to rest, however; landing was only the start of operations.



    Rodina 4 MET 4 days, 11 hours

    The cosmonaut carefully climbed down his LK's ladder.

    It had been a long, hard road to the Moon. The training, the development, the testing, all of it pushing the space program to its absolute limits. They had overcome the back-to-back disasters of the Chief Designer's death and the deadly failure of Soyuz 1, the initial failure and setbacks with the N1 booster- everything. And now, he was here.

    Leonov took another tentative step back, down the slanted ladder towards the surface below. For ground control’s benefit more than his own, He had tried to maintain some amount of running commentary through his time alone on the mission- though, he found himself getting lost in focus, seconds and minutes passing between status reports without a word said.

    "Control, everything is proceeding nominally. I am able to maintain my balance on the ladder without issue. The surface has many small rocks scattered, but I will have no trouble stepping over them.”

    “Understood. Status is nominal.”

    OGFN3nS.png

    [Rodina 4 Commander Alexei Leonov exits LK Rubin to begin his solo moonwalk. Image credit: AEB Digital]
    ----


    The last portion of the ladder was bent at a very low angle relative to the surface. Choosing to bypass it entirely, Leonov shifted to the side, stepping the last short distance to the surface and planting one boot, then another, in the dust. He let go of the ladder and turned, then took a few careful steps away from the lander and turned back to face it. Without the ladder to lean on for support, Alexei could feel just how offset his center of gravity was as he moved - the bulk of his spacesuit’s weight was behind him, mounted in the backpack; with each step, he had to counteract a natural lean backwards to avoid tipping. It wasn’t dangerous, but he might lose his balance momentarily if he weren’t thinking about it.

    Alexei looked up and down at the lander- his lander, for now. Rubin was a unique-looking thing, all metal struts and protruding antennas; her skin of wrinkled thermal covering with a silver-white sheen, like the delicate iridescent wings of a moth. The television camera mounted above the hatch stared down blankly at him, its polished lens reflecting the surface as it transmitted his image back across the gulf of space to the untold many watching across the world.

    He realized he hadn't spoken anything from the surface yet. If the American Virgil Grissom was any example, these first words would no doubt be overblown in their importance; recorded for all time, written in newspapers, flown on banners in the Red Square, engraved on statues lionizing the great Soviet hero-

    ‘Breathe, Alexei.’ The man had to mentally remind himself, exhaling an unconsciously-held breath. Now wasn’t the time to start contemplating the distortions of propaganda- All the time in the world for that later. What mattered now was the mission, being here. He focused on what felt real; the ever-present growling sound of his suit’s cooling equipment, the weight of the bulky integrated backpack pulling him even in the low gravity, the soft reassuring rush of life-giving air against his face. Turning and looking out from his man-shaped bubble of safety, the landscape before him was so very unlike anything he’d ever seen. The color palette, his artist’s eye could observe even through the tint of his outer visor, was entirely foreign to that of home - Earth was blue skies and green hills and brown mud and misty grey cloud; the Moon was grey, yes, but not the cold, wet grey of a rainy morning, nor the warm, dry grey of sun-weathered concrete. It was a kind of stark grey-on-black that was hard to describe, all at once lacking in color and containing a million subtleties of hue, a tableau of alien ashen tones forming a landscape both enigmatic and all-telling.

    The words came to Alexei Arkhipovich Leonov almost without intention, a thought welling up to the surface.

    "This strange world is more beautiful than any painting can capture."

    The January 26th, 1972 lunar landing of Rodina 4 made front-page headlines across the world. An estimated worldwide audience upwards of 70 million watched and listened to the live television and radio broadcast of the moonwalk, and millions more - particularly in the United States - would see the footage on news broadcasts in the following days. For the Soviet Union, it was a reassurance of their own technological might; a display that they were by no means “behind” in the race to explore outer space.

    Commander Alexei Leonov spent just over 6 hours on the lunar surface, with 2 hours walking on the Moon, and another 4 resting aboard the lander before liftoff. While on the surface, he planted the Soviet flag, placed a small plaque commemorating the two cosmonauts (Vladimir Komarov and Yuri Gagarin) and four American astronauts (Theodore Freeman, Charles Bassett II and Elliot See Jr., and Clifton Williams Jr.) who’d died in service of space exploration,[6] collected samples, and placed a series of small scientific instruments including a laser retroreflector and a seismometer powered by a small unfolding solar panel assembly.[7] On returning to orbit, Rubin rendezvoused and docked with Yantar and Leonov performed a second transfer EVA carrying the lunar samples.

    Alexei Leonov and Valeri Kubasov returned to Earth on January 29th as new Soviet icons, showered with parades and honors; personally congratulated by Brezhnev himself, and both awarded Hero of the Soviet Union for a second time.[8] But even as the Union celebrated the triumph of Rodina 4, rivalries between designers and political pressure from above loomed like dark clouds over the Soviet space program, as questions of its future in a post-Moon landing world arose...

    Interlude 8: Nothing Bad Ever Happens to the Kennedys
  • Small Steps, Giant Leaps - Interlude 8: Nothing Bad Ever Happens to the Kennedys​



    The presidential election of 1968 was, by all accounts, one of the most extraordinary and defining moments in American political history.

    Robert Francis Kennedy, having survived an assassination attempt in June of that eventful year, narrowly carried the Democratic nomination at a tumultuous Chicago convention. In the general election, Kennedy faced down Republican powerhouse Richard Nixon, the second Kennedy to do so; from his right within the traditional Democratic voter base, former Alabama Governor George Wallace’s third-party “American Independent” run threatened to split the vote and hand Nixon the win.

    Against all odds, however, Kennedy stuck it out. When the dust settled after Election Day, RFK won the White House by just five electoral votes past the required 270 - the closest electoral margin in modern history. It is much debated whether Wallace’s third-party run secured Kennedy's victory over Nixon by splitting the Southern conservative vote, but it can at least be considered a factor.

    mLp1sjT.png

    ----

    Robert Kennedy was elected on a dual mandate: ending the Vietnam War, and continuing the reforms and progress of the 1960s into a new decade. This first goal materialized within the first 9 months of the new administration, with stalled peace talks started under Johnson finally coming to fruition in August of 1969.[1]

    As for social and economic reforms, Kennedy continued to support and expand Johnson’s ‘Great Society’ programs, and signed a number of landmark bills into law in his first term covering civil rights, housing, labor rights, and environmental protection.

    In terms of space exploration, the second Kennedy Administration would, in the beginning, be defined by the policy set by the first. Robert Kennedy oversaw the fulfilment of John Kennedy’s great decadal goal of landing a man on the Moon. As one Kennedy set a course for the space program of the 1960s, it would be another’s role to do the same for the 1970s as NASA looked to a post-Apollo future. While the space program budget under RFK’s administration decreased from its late 1960s Apollo peak, new initiatives - namely the Apollo Applications space stations, and the Space Shuttle - promised to be just as transformative and bold as their predecessor, greatly reducing the cost of access to space and presenting an opportunity to learn how to effectively live and work in orbit long-term.



    By the start of the election cycle in 1972, prospects remained good for a Kennedy re-election, with RFK riding high on a first term of progress on seemingly all fronts. From within his own party a challenge arose in the primaries once again from Alabama Governor George Wallace (subsequently re-elected to the governorship in 1971), running this time as a Democrat and positioning himself as a “moderate conservative”; Wallace won a respectable number of primary contests across the South and in Michigan, but ultimately failed in the face of a popular incumbent and his own abysmal (to put it lightly) record on race. Kennedy and Wallace exchanged a now-famous “respectful handshake” on-stage at the Democratic National Convention, and that was that.[2]

    The biggest shock of 1972 came not from a primary challenger, but from within the White House itself: Vice President John Connally, former Navy Secretary and Texas governor who’d taken a bullet during the JFK assassination, chose not to seek re-election on Robert Kennedy’s ticket- and endorsed RFK’s Republican challenger, Kansas Senator Robert Dole. Connally, and later in the election Wallace, would spearhead a “Democrats for Dole” movement, a rebellion attempting to break the ranks of Kennedy’s broad 1968 coalition.[3] In Connally’s place as a running mate, Kennedy would select Governor of Georgia James “Jimmy” Carter Jr., a relatively unknown figure on the national stage as yet whose presence on the ticket was hoped to boost Kennedy’s standing in the South.

    Kennedy’s early polling lead was boosted by the echoing fallout of the Chennault Affair, when it came to light in the months following Kennedy’s 1968 win that the Nixon campaign had been in contact with South Vietnamese officials in an attempt to sabotage the peace talks and hand Nixon the election. While Nixon himself faced no legal repercussions, both his running mate Spiro Agnew and Republican Women for Nixon Committee chairwoman Anna Chennault would be charged with violating the Logan Act by early 1971. The Chennault Affair effectively ended any prospect of a third presidential run for Nixon, who appeared only rarely during the 1972 election cycle, speaking at the Republican National Convention and at a handful of campaign rallies.[4]

    After the Democratic and Republican conventions of 1972 in July and August respectively, the field emerged as Robert Kennedy and Jimmy Carter on the Democratic side, versus Bob Dole and running mate Nelson Rockefeller on the Republican side. Dole presented himself as the candidate of “law and order”, railing against the “radical liberal policymaking of the Kennedy dynasty.” He characterized his intended voter base as the “real America”, now famously stating in a television interview that “[...] there is a great, silent majority of Americans who are dissatisfied with the way this country is going, after over a decade of Democrat leadership.”

    While Kennedy’s initial lead had been strong, In the final months of the election cycle things began to appear less certain as Dole climbed in the polls. By early October, polls that had consistently shown a Kennedy victory began to indicate the possibility of a surprise Dole win, coming down largely to Kennedy’s loss of Texas with Connally off the ticket, and Dole’s presumed win of New York with Governor Rockefeller as his running mate. Final polling in the first days of November showed that things could, really, go either way.

    America went to the polls once again on November 7th, 1972, to decide yet another close presidential race. In the end, RFK would thread the needle once again, even increasing his electoral margin from 1968 by 2 votes. It was the second-closest electoral win in history, and the closest two-candidate race, by the same president who’d threaded the needle in 1968. Lightning had struck twice, so it seemed.

    ----

    There are a number of factors that can be considered relevant in Kennedy’s re-election win. In terms of Electoral College votes, RFK narrowly holding onto New York despite Dole’s running mate being governor can certainly not be discounted, nor can the significance of California and its 40 electoral votes, which had gone to Nixon in 1968.

    Beyond raw numbers, however, Kennedy’s win can perhaps be attributed most to two constitutional amendments - one passed, and one yet to come. Firstly, the ratification of the 26th Amendment to the Constitution in 1971, lowering the voting age to 18, can be seen as a massive contributing factor to Kennedy’s re-election win, given RFK’s popularity among the young Americans of the ‘counterculture’ movement when compared to Dole’s typically older, more conservative voting base. Secondly, the ongoing campaign to ratify the Equal Rights Amendment - a constitutional amendment to guarantee equal legal rights for all American citizens both male and female - was a central part of Kennedy’s campaign messaging of continued social progress, and won the president support among women increased from an already-high margin. The Dole campaign remained largely silent on the ERA, with Dole commenting at one point that it was “a matter for the state legislatures now.” Kennedy’s vocal support of the ERA during the 1972 election cycle and subsequently during his second term would contribute to its final ratification and addition to the Constitution by early 1976, as the 27th Amendment.[5]



    If the 1968 election can be seen as the beginning of a shift in American politics, 1972 can be considered the further crystallization of those changes. With the exception of Georgia, the South now swung firmly Republican; and a number of prominent formerly-Democratic politicians and figures crossed party lines and eventually changed parties altogether, most notably then-Vice President John Connally; this seeming realignment in the parties would set the stage for elections and legislation for decades to come, and whose effects we are still seeing in the modern day American political landscape.

  • Small Steps, Giant Leaps - Part 9: A Home in Space​



    May 23, 1973
    Skylab 2 MET 17 days


    Out of all of the stunts that Pete Conrad had pulled in life, this one was probably the craziest.

    Here he stood- so to speak- a dozen meters away from his only safe ride back to Earth, clinging to the side of a spaceship with a bad case of separation anxiety. Even better, he and Joe Kerwin were working with a mission procedure that hadn’t existed until all but 4 days ago, on hardware that wasn’t ever intended to be touched by man after it had blasted off from Cape Kennedy.

    Hell of a turn of bad luck, then, that of all the payloads for a Centaur upper stage to fail to separate on, it just so happened to be their Apollo Telescope Mount. Even now, as he and Joe worked to unstick Roadrunner from its ride, the Centaur was still periodically venting hydrogen, giving Paul Weitz back in Coyote no end of trouble maintaining attitude.

    “Okay Houston, I’ve got everything in position up here- I’m gonna try giving it a heave, see if we can’t get these two apart…”
    “Copy that, Pete.”

    In his gloved hands, Pete gripped an improvised lever - in reality a spare bit of metal framework from inside the station, with a grey-tape lanyard to hopefully prevent it from floating off into space. He and Joe had spent the last ten minutes carefully wedging their highly-advanced repair tool in between the ATM and the Centaur’s payload adapter, and now all that was left was to apply as much pressure as possible, and hope it was enough to do the job.

    Pete took a deep breath, and pushed down on the lever as hard as he could. Much to his annoyance, Newton’s laws still held in space, and as he pushed down, it had more the effect of pushing him up rather than wrenching the spacecraft from its upper stage. Goddamn conservation of momentum. Pete steadied himself and took a moment to reposition, attempted again to no avail, and began preparing for a third try but stopped as an idea hit him.

    “Hey Joe, can you grab onto me, and really try to hook your feet on down there? See if we can’t get some more leverage, keep me from bouncing around…”

    "Okay, Commander- there we go."

    Now more firmly anchored by his Science Pilot, Pete tackled the problem once more, pushing as hard as he could. The metal rod held firm at first, unyielding, before flexing slightly, and then-

    “C’mon- shit!

    Something, whatever failed bolt or fastener was left hanging on after the Centaur’s half-cocked separation attempt, gave way with a snap. Pete couldn’t hear it, but he sure as hell felt it, the released tension hitting him with a jolt that threw him off his balance as he exclaimed in surprise, losing grip on his lever in the process, which flew lanyard-and-all off of his wrist and into the void. Joe Kerwin kept a vice hold on Pete’s legs, stopping the Commander from floating off much as the Centaur itself had slowly begun to. Pete caught his balance after a moment, and steadied himself back against Roadrunner’s side, breathing heavily through the sudden surprise.

    “There we go.” Joe repeated, watching as the upper stage drifted slowly away from the stack.

    "Houston,” Pete said, cracking a grin, “I am pleased to inform you that our little improvised solution has provided the desired result.” He looked down towards the strange little spacecraft they’d just freed, delicate solar panels folded up against a body of trusswork, with that oh-so-familiar LM cabin up on top docked to the Command Module. “Pass my compliments on to the guys at Grumman- Roadrunner's a mighty fine piece of machinery, and I can't wait to fly her back to Skylab."

    Just another day at the office for the crew of the world's first space station.

    The first half of the 1970s, undoubtedly, stands as the high-water mark of the first age of space exploration.

    While the first four men walked on the Moon in 1969, it was 1971-1972 that saw the Apollo program truly begin to excel, as the three “J-class” lunar missions pushed the bounds of scientific and technological daring; the crews equipped with upgraded hardware and increasingly in-depth geology training.

    Apollo 16, the first of the J-missions, saw Commander David Scott and Lunar Module Pilot James Irwin test a new “Lunar Roving Vehicle” as they explored the Descartes Highlands on a 3-day surface mission. In lunar orbit, Command Module Pilot Alfred Worden observed the Moon with an upgraded suite of science instruments mounted in the Service Module, data and film from which he would retrieve en-route to Earth in history’s first deep-space EVA. On Apollo 17, CDR Eugene Cernan and LMP Charles Duke identified geological signs of a volcanic history at the Marius Hills in Oceanus Procellarum. Apollo 18, commanded by Richard Gordon (who’d previously flown on Apollo 12 as CMP) would smash every record set by the previous two; remaining on the surface at Hadley Rille for 76 hours[1] and collecting the most samples of any J-mission, thanks in no small part to LMP Harrison “Jack” Schmitt, the first professional geologist on the Moon. Upon the mission’s return to Earth in December 1972, Schmitt described the Moon as a "geologist's paradise.”[2]

    Right as the “Lunar Decade” seemingly hit its stride, however, NASA took a moment to pause. 1973 would pass without a single Apollo mission to the Moon. It would not be until the latter half of 1974 that NASA would return to the Moon for the final two Apollo lunar missions, Apollo 19 and 20 respectively. The year-long break in between wasn’t without purpose, however; it would be focused on NASA’s long-awaited space station, Skylab.

    The first of two planned Saturn-derived space stations in the Apollo Applications Program, Skylab was a so-called “wet workshop” design, with the primary crew habitation facilities situated inside of the hydrogen tank of a converted S-IVB upper stage, designated the “S-IVB Workshop”, or S-IVW. While primarily intended to save money by launching on a Saturn IB (rather than the larger Saturn V that would be needed for a “dry” station of similar size), the S-IVW was, in the end, also designed with further Apollo applications in mind; such as a Saturn V “wet workshop” lunar space station, or a manned flyby of Venus.

    The various components of Skylab began stacking in early March of 1973 with the Saturn S-IB first stage and interstage skirt, the only "normal" Saturn IB components of the Skylab 1 stack. Next came the S-IVW, already integrated with the Saturn Instrument Unit that would control the rocket during launch. Last to be added was the combined Airlock Module and Multiple Docking Adapter, the latter with its two “drogue” docking ports (to accommodate an Apollo CSM and a rescue vehicle) and a singular “probe” docking port to accommodate the Apollo Telescope Mount, with its LM-derived cabin.

    Stacking of Skylab took well over a month, with preflight checks, rollout, and a full Wet Dress Rehearsal occupying the rest of April. Finally, the world’s first space station lifted off from Pad 39A on May 5th, 1973, and reached orbit without incident, the J-2S upper stage engine injecting the wet workshop into a circular 400km, 31.5° inclination orbit. When telemetry indicated a successful deployment of the station's twin solar arrays upon reaching a stable orbit, program managers dreading potential failures and a rushed rescue mission breathed a sigh of relief.[3]

    Skylab’s first crew - Commander Charles “Pete” Conrad, Science Pilot Joseph Kerwin, and Pilot Paul Weitz - would follow their space station to orbit from Pad 39B hardly a day later on May 6th. Their mission was designated Skylab 2, Skylab 1 having been the station’s own launch. Skylab 2’s launch proceeded nominally as well, save for a small electrical glitch caused at liftoff by a change to the pad equipment, which was found and corrected for future launches. The crew performed the first American rendezvous in Earth orbit since Apollo 9, and after a brief scare where initial attempts to engage the docking latches failed repeatedly, successfully docked with Skylab and entered to begin assembling their home in orbit.

    Outfitting the Workshop proved to be an arduous task. To start with, the supplies required were so tightly packed into the Airlock Module and MDA that there was barely enough room for an astronaut to crawl through, making supply transfer difficult. It would take four days to move the supplies into the Workshop alone, and another three to bring the station up to minimum requirements for habitation, over a day longer than NASA's initial estimate. The crew would finally begin sleeping in the Workshop on May 14th, a week into their month-long mission aboard.

    Skylab’s Apollo Telescope Mount, the final component needed for the station, launched atop a Titan IIIE/Centaur on May 19th. Rather than attempting an as-yet untested automated rendezvous and docking with the station, the mission plan called for the ATM to be launched into a nearby orbit, from which the crew would retrieve it with their Command/Service Module and bring it back to Skylab to be flown in to dock with the station by the Commander. Fitting this complex “chase-and-capture” excursion away from the station and back again, the crew of Skylab 2 nicknamed their CSM Coyote, and the Apollo Telescope Mount Roadrunner, after the animated duo from Looney Tunes.[4]

    ----

    Although Roadrunner’s ascent to orbit proceeded without issue, upon reaching its target orbit, telemetry indicated that the Centaur upper stage had failed to automatically separate from its payload. A manual command to separate also failed to work. With one of the primary scientific components of Skylab in jeopardy, NASA quickly began planning to address the issue. Coyote’s departure from Skylab was delayed by two days, as a contingency EVA was planned to attempt to unstick the fragile and expensive hardware from its upper stage. The crew of Skylab 2 finally left the station on their two-day excursion on May 22nd, spending a day in a phasing orbit before rendezvous and docking with Roadrunner.

    After a complex, multi-hour EVA by Conrad and Kerwin, the crew were able to lever the Apollo Telescope Mount free, using an improvised crowbar to tear the partially-separated Centaur off where it was stuck. With the drama of an orbital rescue behind them, the Apollo Telescope Mount’s solar panels were deployed, and the combined CSM-ATM stack flawlessly re-rendezvoused with Skylab a day later. After closing to a hundred meters from the station, with Coyote stationkeeping, Roadrunner undocked with Commander Pete Conrad at the controls. Without issue, the one-man spaceship flew home to Skylab’s zenith docking port, followed shortly after by the CSM with Kerwin and Weitz aboard.

    With the crew reunited, normal operations aboard the station resumed, now with a campaign of solar and celestial observation in addition to the previous work. The crew of Skylab 2 spent their remaining week and a half in orbit outfitting the Workshop, operating the Apollo Telescope Mount, and performing various other scientific and medical experiments, as well as undertaking a final EVA to remove and replace film from the ATM.

    After 30 days spent in orbit with 27 of those days aboard Skylab, Conrad, Kerwin, and Weitz boarded Coyote and left the station, splashing down in the Pacific Ocean off of Hawaii later that day on June 5th. America's space station was up and running, ready to support future crews.



    In looking at the crewed space programs of the early 1970s, a striking comparison can be made between the American and Soviet examples as of the middle of 1973.

    On the American side, the Apollo J-class missions carried two astronauts each to the lunar surface for expeditions up to three days in length, returning well over 150 pounds of samples each (Apollo 18 returning the most of any J-mission, at 246 pounds of lunar rock and soil). Skylab was capable of supporting a crew of three on orbit for weeks at a time, with months-long expeditions planned on Skylab 3 and Skylab 4 later in 1973. On the Soviet side, the N1-L3 lunar architecture that supported Rodina could only deliver a single cosmonaut to the lunar surface, for a stay of less than half a day and a sample return capability of only a few kilograms. The Soviet space station program meanwhile, by mid-1973, hadn’t even successfully gotten off the ground, much of its funding having been redirected to the lunar push in its infancy. While the later 1970s would see the more successful beginnings of a Soviet station effort in earnest,[5] for the time being, the USSR remained without a lasting outpost in Earth orbit.

    The efforts of the Soviet space program cannot be discounted, and the samples returned by Rodina were, as with any lunar samples, invaluable to science. Both programs were great feats in technological prowess and human bravery, undoubtedly. All that said, it is Apollo that reshaped our modern understanding of the Moon’s formation and evolution; it is Skylab that first showed us man’s ability to live and work in space long-term.
