Apollo-Part 18
Kerim Kerimov who was in charge of the Soviet Space program, directed a complete overhaul of the Soviet Union space program to streamline its design and operations. He needed to end the intrigue and infighting that went on in the Soviet space program between the various design bureaus. To this end Kerimov would create a new single design bureau called NPO Energia for the Soviet Space program. This would help eliminate all the infighting that went on between the current design bureaus, everyone needed to be focused on one goal which was the success of the Soviet space program. The first order of business for NPO Energia was to design and build a Liquid Hydrogen rocket engine that could be used to replace the upper stage on the N1F rocket. Kerimov knew the N1 rocket had some serious design flaws, yet after years of development it had evolved to the point that its design flaws were mostly compensated for. It would be better to start with a clean sheet launch vehicle design but this would have taken too long and would be unacceptable for Soviet Leadership. The N1 rocket would have to continue to mature and evolve to meet the needs of the Soviet lunar program and Beyond Earth Orbit operations. If the Soviet Space Program hoped to match or exceed the US space program an increase of resources was needed. A decision would have to be made by the leadership of the Soviet Union if they wanted to commit those resources. Kerimov would prepare multiple options that needed to be reviewed and a decision made by Soviet Leadership.
The first option which was to continue to allocate the current amount of resources. The Soviet Union would have to retreat from the Moon and focus on Earth Orbit and modular Space Stations for the Soviet Manned space program. Missions beyond Earth Orbit would be undertaken by unmanned probes. The next option was current minimal continuation of the Earth Orbit missions with continued small space stations. The lunar program would continue with a selection of a site for a permanent lunar base. This would require more resources than currently being allocated to the Space Program but would allow the Soviet Union to at least match the US. A key part of this would be an evolution of the N1 rocket to allow larger payloads to the lunar surface including a Hydrogen rocket engine for use as a N1 upper stage. The Soviet Union would also push forward in unmanned probes since the Americans were focused so much on manned missions. The last option which would require the most resources was the continued development of both a lunar base and a module space station with an eye toward a manned Mars mission sometime before 1990. This would require the development of a brand new heavy lift rocket to replace the N1 eventually. However the N1 would need to continue to be used in the short term. The Soviet Union needed a reliable heavy lift rocket that could come close to matching the lifting power of the Saturn-VB if it was going to beat the Americans to Mars.
After the disaster of Zvezda-2 for the Soviet, the usual NASA critics were unusually silent. Administrator Paine had been receiving criticism from Politicians and several critical editorials were written in newspapers about the slow pace of the US manned space program. Now the critics of Paine’s slow and methodical approach to the US spaceflight program were silent. In meetings with Robert and John Kennedy, Paine emphasized how he tried to balance keeping the US manned space program safe as possible while still moving forward on exploration. Manned Space flight was extremely hazardous by nature and a methodical approach was needed to minimize the dangers. Robert emphasized how he had the full support of the Kennedy administration in his decisions. He wanted Paine and John to work on planning for expanding of NASA missions beyond just the lunar LESA landings. Robert thought he could funding for NASA to get back on track with the Independence Space Station. He also figured that possibly get funding restored for the EML-2 space station and the Hermes Mars-Venus Flyby was possible. Also with all the noise about a Soviet Lunar base that he wanted NASA to update studies looking at US lunar bases for the next step beyond the LESA program. Bobby thought he could possibly use the Manned Soviet Lunar landing, despite its failure to their advantage to get more money for the US space program. During a meeting in the Oval Office on December 5, 1974 with NASA Thomas Paine and his brother John. Robert asked Paine about where Apollo-21 and Apollo-22 currently stood with their launch preparations.
“Mr. President, the preparation is going along well. Apollo-21 is planned to launch on April 5 of next year. If this mission encounters no issues then Apollo-22 will be landing in the Marius Hills area on October 29 of next year. As we had previously discussed the mission will be planned for 3-months but we can extend the mission up to 6-months. As of right now we are encountering no major issues that would stop the landing. The biggest open issue is the LESA base power plant. It is tricky getting the Hydrogen and Oxygen from gas back into a Cryogenic Liquid to be used by the fuel cell. General Electric thinks that they have worked out the issues. We anticipate possible issues with the system working correctly for the full 6-months on the lunar surface. The crew is receiving extra training with the power plant in-case any repairs need to be completed during the mission. The other open issue is how well the actual Lunar-landing-Vehicle-base will land un-manned on the lunar surface. We have never attempted a manned or unmanned lunar landing with such a large object before on the lunar surface. We will be attempting to land almost 70 tons of Mass on the lunar surface. There is a big question mark if we will be successful. While we have been testing the LLV in Earth Orbit we have never attempted a lunar landing. “
Paine sighed audibly.
“I would like to announce that the first lunar landing LLV-base is a test mission to validate the vehicle in landing configuration. If we can get it down successfully we can then follow up with a manned landing a month later.”
Robert Kennedy looked at John and Paine. “You mean similar to how the Soviets announced the LK-lander base?”
“Yes Mr. President.”
“Ok Tom I can go with that. I am not sure if the press will go along. They will probably see it as a mission attempt not a test, no matter how we spin it. However we will emphasize that it doesn’t make budgetary sense to send the LLV-Base all the way to the moon to attempt a landing and if it works to not follow up with a manned landing to make use of this base. We will need to emphasize we are trying to save money by making best use of the test mission since it will be unmanned. Let’s just hope you guys are good and are successful because the Soviet’s landed the LK-Habitat base on the first attempt. “
“I know Mr. President.”
“John what do you think about all this?”
“Well Bobby, we got a lot of pressure for NASA to be successful with this first Apollo-LESA mission. I think we can use the increased activity of the Soviet Lunar program to good effect to secure increased funding for NASA. Right now NASA is planning LESA missions at the rate of 1 a year.”
“One a year? John”
“Yes, one a year that is all that funding will allow. Also we have to consider rocket production. At the current rate of production, 3 Saturn-VB’s are produced a year. Each LESA mission requires 2 Saturn-VB launches. Which means that we only have enough rockets to launch 3 LESA missions over 2-years. So at maximum we can do only one mission every 8-months at the current Saturn-VB production rate. This year is the first year that 3 Saturn-VB’s will be produced. The vehicle wasn’t easy to design and develop. North American, sorry Rockwell International and Boeing have worked the manufacturing issues outs for the 1st and 2nd stage. The 3rd stage progressed faster since it is smaller and had less development issues. McDonnell also had the advantage that the S-IVC is used on the Saturn-IC and it could progress faster into flight testing. From experience the bigger the stage the more headaches that occur during development, testing and then manufacturer. The issues we had were easier than the issues with the Saturn-V, but still the size of the stages we are dealing tend to create problems that nobody had previously thought about. For example we had roof clearance issues with the new 1st stage at Michoud that required some structure changes. NASA prefers to have all 3-stages finished, tested and delivered to Michoud at a minimum of 12-months before a planned mission that they will be used on. Even 12-months sometimes is cutting things close. All the stages are too big to move by air so each stage has to be transported by sea, which takes extra time and planning. Once at Michoud it is inspected again and then either moved by Sea to the Cape or put in storage until it is time to move to the Cape. Once there each stage has to be moved off the barge and into the VAB and then inspected again before it is stacked. The launch vehicle for Apollo-21 was only delivered to Michoud in March of this year. It is now in Vertical Assembly building being checked out and stacked for the launch in April of next year. The 2nd Saturn for Apollo-22 was only delivered to Michoud last Month. Also remember that is just for the launch vehicle, we then also have to deal with the two different Lunar Landing Vehicles. You also have the Apollo CSM and don’t forget about the four 260” Solid Rocket Boosters that are required for each Saturn-VB so that each one has to be delivered and they weigh 1600+ tons when loaded. The AeroJet facility is in Florida, which is reasonably close by which helps in timing deliveries. You also have a Apollo-Centaur stage for each launch that has to be delivered and test. Oh I almost forgot you also have the Instrument Unit for the Saturn Rocket that controls the entire vehicle during its launch. Not to mention all the other items from spacesuits, consumable supplies inside the LLV’s and the MOLAB vehicle. All these items that are produced by various companies and all have to come together on-time or the entire timing of the launch gets thrown off. Not to mention that depending on a particular Lunar landing site we only have a 24-48 hour window each Month for launch so we have the correct lighting conditions for the manned landing. Luckily with the un-manned LLV-LB we have more flexibility in regards to lighting conditions." John stopped and smiled at his brother
Robert Kennedy, was just starting to realize how complicated the space program was. He had no idea all the details to pull off an Apollo launch. However his brother seemed to revel in the details of the space program. He was glad he had his brother to help him with all of this because he was completely out of his depth.
“Ok John, I can see that going to the Moon is a lot more complicated than I thought.”
Paine cleared his throat and drank some water trying not laugh at this exchange between John and Bobby. When John Kennedy left the Presidency his interest in space never stopped and now after several years of being involved with NASA at high level he had a better grasp of the details than any politician and he quietly suspected even some NASA managers. Which had presented it’s own challenges for Paine. Shortly after John Kennedy’s Presidency came to an end he showed up at the Manned Spacecraft Center in Houston and as some people put it, he never really left. John Kennedy was only 52 when his Presidency ended and despite his medical issues he wasn’t ready to retire, and write his memoirs. It wasn’t helped that within a week of him leaving office Jackie Kennedy had filed for divorce. His predecessor James Webb, after realizing that Kennedy was squatting in various vacant offices in the Manned Spacecraft Center had assigned the ex-president an office in the Administration building and a secretary. This didn’t help Paine much when his own office was in Washington DC and Kennedy refused to take Paine up on the offer of a office at NASA headquarters in DC. John Kennedy had created his own unit inside of NASA and the only reason that he got away with it was because he was a former US President. When Paine had tried to talk about it with Lyndon Johnson after taking over for Webb. President Johnson only smiled and told him that he would figure out the best way to handle Kennedy. Now with Robert Kennedy in office the situation wasn’t getting better. In Paine’s view there needed to be clear lines of responsibility and reporting in any organization and Kennedy’s own office threw this into chaos at times. Kennedy officially didn’t report to anybody except the President, and even then he wasn’t sure sometimes. It didn’t help that Kennedy’s NASA office had slowly grown somehow. He now had former astronaut Bill Anders working with him and Alan Shepard would also drop by as his schedule allowed. Another recent addition was General Sam Phillips who had retired for the USAF and now was assisting Kennedy for free on a part-time basis. He finally had to assign someone to try and keep tabs on what John Kennedy and his “NASA gang” were up to. Having John Kennedy around was kind of like playing with explosives and Paine was never sure when something was going to blow up in the heavily bureaucratic NASA. He still hadn’t figured out how to best handle the Kennedy problem so he decided his best course of action right now was one of containment and observation.
“Yeah Bobby, going to the moon is complicated and landing on the moon is even more complicated. The entire Apollo program has been more about project management of large engineering projects than anything else.”
“So what do you recommend we do John?”
“Right now we need more funding to get the Independence Space Station back on track. I don’t recommend we speed up the lunar landings and we keep them at one mission a year. For long range planning we continue to fund the replacement for Big Gemini and fund a Space Station at EML-2. We have most of the hardware for the EML-2 space station we just need the funding for operations. We cannot afford to abandon Skylab-B until Independence is up and operational, having a working space station in orbit is a national asset that needs to be preserved. Also having a space station makes it cheaper to do research that requires a microgravity environment. We need to increase the funding to get the Independence Space Station back on track. People don’t realize the return on investment that a work space station gives. Instead of just sending astronauts up for a couple of weeks at a time we can send them up for months at a time and they can do extensive research while on the space station at lot lower cost per man-hour than a conventional space mission. We should continue the long range planning for creating a lunar base, but more funding needs to be allocated. Part of the LESA exploration will be determining the best location for a lunar base. If you think we can get that funding from Congress we can get everything on track and make sure the Soviet’s and the US public know who is dominating in space.”
Robert looked at Paine after John finished “Do you agree Tom?”
Paine cleared his throat “Mr. President I liked the priorities that your brother has laid out and we can work with that. I would like to add a couple of additional requests. With the failure of the Soviet lunar mission we need to reexamine failure options for a lunar mission. I think we need to look at possibly staging landings out of the proposed EML-2 space station and have a permanently docked lunar rescue vehicle. I don’t want to see US astronauts dying on the lunar surface or in lunar orbit and by staging out of EML-2 we can increase the safety of the lunar missions. “ Paine paused he could see John Kennedy wanting to say something but he then decided not to.
“I also want to see about expansion of Launch Complex 39 to make launches more efficient. I want to have all manned Saturn launches be launched from Complex 39. The issue is that the Saturn-IC uses a Solid Rocket Booster for the first stage which means we cannot stack the launch vehicle in the Vertical Assembly Building because of the danger of having a fully fueled rocket inside this building. I would like to start the construction of two separate Vertical Assembly building that would be smaller in scale and have only 1-bay in each building. These buildings could support the launch of Either the Saturn-1C or Saturn-III rockets. The buildings would need be separated from the Vertical Assembly building. This way we can stack a Solid Rocket Booster inside a building and then transport to the pad when the stacking and checkout is completed. Instead of stacking at the pad which is what we have to do now. This will also allow to have all manned launch from Launch Complex 39.”
Robert looked over at his brother who nodded at him.
Paine caught the nod from the John to his Brother. Paine had very quickly realized that as long as he had John Kennedy’s support on something for NASA he could just about guarantee that his brother would agree. This also meant that if John Kennedy didn’t like something he was proposing it was probably going to be denied. He would have to keep this in mind.
“That is fine with me Thomas, this all sounds good thank you both of you for coming today.”
“Actually one other thing Bobby.” Kennedy had raised his finger.
“Go ahead John.”
“We need to amend the Saturn production contract which will also require some additional funding. The HG-3 engine, which is a new more powerful upper stage engine has finished development and ground test and I think we should shift production to take advantage of this new engine at the earliest opportunity. “ Kennedy paused and looked over at Paine.
“Do you agree Tom?”
Paine nodded his head.
“Sound good Bobby?”
“Ok, John get some numbers on everything and I will work on seeing what we can get on the hill for funding. Well if you guys are done trying to empty my pockets. I think we can wrap this up.”
John got up out of his chair and a Secret Service quickly agent appeared with a wheelchair and Kennedy eased himself into it. Paine and then John left the Oval office. Once outside in the hallway John stopped Paine.
“Do you have a couple of minutes?”
“Sure Mr. President.”
Paine walked with the John Kennedy as his wheelchair was pushed out to rose garden near the west wing of the White House.
“So Tom about staging out of EML-2. I think there might some alternatives and we can still get increased safety.”
Thomas Paine sighed “Mr President” John raised his hand
“Tom in private just call me John.”
“Ok John, I am really concerned about having a crew stranded in either lunar orbit or on the surface. We almost had the crew of Apollo-19 stranded on the surface, that was a close call. It gives me nightmares. We now have two cosmonauts dead up there. Sometimes I question if the entire lunar exploration program is worth it.”
“Gives me nightmares too Tom, but we have smart people that think of contingencies and the backup system worked with Apollo-19. The astronauts in NASA know the risks they take. Nobody is under any illusions that spaceflight or going the moon is routine. I think we will discover that those two Cosmonauts were killed by incompetence and sheer hubris by the Soviet manned space program. The important thing is to remember that space exploration is dangerous and we can only eliminate so much risk before we just start spinning ourselves in circles of money and we make no forward progress. Also never lose sight of what could go wrong and become complacent becomes I can guarantee you that being complacent will get people killed. I understand that you want to stage the lunar landings out of EML-2 and pay Grumman to create a Lunar rescue vehicle that can be in long term hibernation at EML-2 in case it is needed. “
“Yes John I do. “
“I think you might want to consider a proposal from McDonnell I heard a couple of weeks ago that is intriguing. That I think could work better for the program and still give you the safety benefits you want. “
Paine sighed “Ok, I have never heard any proposal by McDonnell on this.”
“Well you know the HG-3 engine has completed its development. “
Paine nodded his head.
“I have had some of my people looking over some numbers, the Saturn Launch vehicle Manufacturers Rockwell, McDonnell Douglas, Boeing and AeroJet all think we should look at moving to what they call a block-II series of the current line of Saturn rocket stages. “
“Ok John you lost me, what does that have to do with lunar mission contingencies?”
“Just hear me out Tom. The Saturn VB stages in the rush to get into production are all over-engineered for what they do. Which means they have more mass than they need. A improvement of the mass fraction by 1% maybe 2% can be achieved and still retain all the necessary structural margins for safety. The numbers look solid. To get the Saturn-VB and IC into production some assumptions were made and the manufacturers errored in the side of caution. Which isn’t a bad thing thing when rushing to develop a new stage. The reason it wasn’t an issue for mission planning is the VB was so powerful that they still hit their payload targets and we didn’t see a constant growth in mass of Apollo spacecraft.”
“Ok John, I am still trying to see the connection.” Sometimes talking to John Kennedy was exasperating.
“You will Tom. AeroJet has also been closely tracking the performance of the Solid Rocket Boosters and the re-use program. The numbers don’t pencil out, it just isn’t cost effective to have the things splash down in the ocean and fish them out and refurbish them. It would be better to construct a more lightweight Solid Rocket body that is disposable. So this means the Saturn-VB could lose some significant mass in the stages. This reduction in mass along with the HG-3 engine should allow launch payloads of around 150 tons to the Moon. “
“That is a lot of payload John.”
“Yes it is, a lot of payload. Now lets discuss lunar contingencies and how this all fits together. McDonnell Douglas has been continuing to work on Big Gemini upgrades and they presented me a design for a lunar mission “Big G” with a beefed up heatshield and engines. The entire Cargo module would be replaced with a Service Module with a pressurized tunnel to allow aft docking to the LLV. The Service Module would use a cluster of three engines that are derived from the LLV ascent engine. By having three engines you have a lot of redundancy for TEI. “
“So instead of depending on one CSM engine firing we have three engines?’
“Yes and the Big Gemini has another advantage. Already mission planners are running into possible planning issues with return capability of CM. There just isn’t enough room in the CM. The “Big G” has triple the internal volume in it’s reentry vehicle of the CM and has a lot more bring back mass. This also means no Multi-mission module and the “Big G” is designed to be re-usable. At the same time we eliminate water landing’s and the logistical challenges that they represent. “
Paine paused to take this all in. “Ok that could work to make sure the astronauts are not stranded in lunar orbit. How about getting off the lunar surface? What happens if the ascent module engine doesn’t ignite.?”
“If that happens they have access to the LESA base if they are on the lunar surface. The LESA base has emergency rations and they could easily survive another 60+-days on the lunar surface. They wouldn’t be comfortable but they could survive and wait in the LESA base for rescue. Grumman was working on a modified LM before we went with LESA base route called a LM Cargo and it had a overall mass of around 16-tons and could transport about 5-tons to the lunar surface. With the HG-3 engine, the Saturn weight reductions and a Apollo-Centaur on the Saturn-IC could launch 20 tons to the moon and a Saturn-IC is much easier to prepare in 60-days for launch than a Saturn-VB. With 5-tons we could easily transport enough supplies to keep a crew alive for another 4-months. So this gives us at least 6 months to prepare a Saturn-VB for a rescue mission which is much more manageable and safer timeframe. Also we then have a lunar cargo module that can be launched on a Saturn-IC and we can re-supply a LESA Mission if we want to extend the mission or send additional supplies. Which is much more effective than developing a lunar rescue vehicle that sits at EML-2 to hopefully never be used. We can wrap up together the switch to Big Gemini, the block-II Saturn rockets and the LM Cargo as a single program to improve mission safety. John Kennedy leaned back in his wheelchair.
Tom paused and was considering what John had just told him. Why had this “Big Gemini” proposal never crossed his desk? He sometimes worried that what he was being allowed to see what being filtered to much. Was he that out of touch sitting at NASA headquarters. It was intriguing and the possibility of being able to land supplies on the lunar surface using a much cheaper Saturn-IC could be very interesting. John didn’t just pull this out of thin air. Somebody had done some work on the engineering for this. Paine had a idea, maybe instead of trying to contain John Kennedy, he needed to work with him and give him a direction? Kennedy because of his position didn’t have the filtering that he had to deal with being the head of NASA.
“Ok John, you have my attention. Why don’t you have your team in Houston work with the various parties involved. I want to see on my desk in 2-weeks a study on the proposed mass reductions for the block-II Saturn stages using HG-3 engines. I also want to see some realistic time plans and cost for phasing in the new HG-3 engine and the mass reductions. I also want to see a study on the cost of the recovery of SRB’s versus not recovering them. No AeroJet bullshit, I want to see the numbers and their costs. “
Paine paused, he could see John had a small notebook out and he was writing in it.
“I also wanted to see a study on the proposed lunar “Big Gemini”. I want to see some numbers, especially timing and cost. I also want to see the proposal on this Lunar Module cargo vehicle. ”
Tom paused “I would take it you wouldn't be telling me this if you didn’t have some of this information already. “
John smiled “I think I might just have some of the information you are asking for already Tom.”
“OK John, should we get out of here? It is getting a little chilly?”
“Yeah I think it is time we depart.” John waived to a Secret Service Agent who came over to push the President.
Tom waved him off. “John, let me push for a bit.”
Tom Paine started pushing John Kennedy in his wheelchair out to their waiting cars
“John, When are you flying back to Houston? I wanted to see if you had time to do dinner tonight?”
“I wasn’t planning on flying back till tomorrow. That sounds great lets do dinner. Tell your wife to come. I think I have a date lined up tonight. We can have a double date. “ John smiled and winked at Tom. John Kennedy was well known among the secretarial staff at Houston. Tom made a point to make sure only young unmarried secretaries were assigned to John Kennedy's office.
“Well if you don’t mind I will come back with you to NASA HQ. I have a few phone calls to make to get my staff working back in Houston on what you asked for.”
Tom Paine and John Kennedy left the White House together and Tom was in a much better mood now than when he arrived.
