    Small Steps, Giant Leaps: How (Almost) Every Apollo Astronaut Made it to the Moon
    Threadmarks: 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...

    Find a POD: Orion doesn't survive the cancellation of the Constellation program

    So I've been playing around with a conceptual 2010s spaceflight timeline, and the big change is that Orion is cancelled with Constellation, and NASA starts a "Commercial Exploration Program" for commercial lunar crew capsules (SPOILER: They pick Dragon and Starliner). This leads to less money...

    Thoughts on APP Mannned Venus Flyby?

    Out of the many post-Apollo plans, one of the more interesting proposals was the Manned Venus Flyby. Using a single Saturn V, the CSM, and an S-IVB "wet workshop," NASA could have accomplished the manned interplanetary voyage in the 1973-1974 time frame. The mission schedule would look something...
  4. Johnson or Humphrey win in 1968, what happens to NASA?

    So, as I understand it, the 1968 was a pretty close election. If Johnson had handled Vietnam better, it seems to me that he could have won it. And even if he hadn't, had he let Humphrey be his own man, it seems to me that the VP could have gotten the votes to secure the presidency. So what...
  5. The Dream is Alive
    Threadmarks: Introduction

    So,yet another timeline from LordandsaviorKloka, he who is infamous for starting promising stuff and then abandoning it. Don’t blame the man,blame the muse. But your 21st Century Future thing is still on,right? Right. What’s this,then? A timeline where the winds of fortune blow ever in favor...

    Ares I Retained

    I've been lurking around the forum for a couple years now, and read a lot of space timelines here. I bit the bullet and made an account today because I've been privately mulling over this timeline idea for a while, and think I need some help. The basic idea here is that instead of cancelling...
  7. AHC: Bob Zubrin as NASA Administrator

    Let's discusse ways of getting Dr. Zubrin as NASA Administrator and getting his goals achieved: Mars Direct starting between 1990 and 2000, nuclear spaceships, and so on. Are there ATLs here where Dr. Zubrin gets the job and his goals achieved?

    Realistic Soviet Lunar program leading to American manned Mars landing preferably without a POD before 1966

    So, I've been wondering what the possibilities are when it comes to creating a timeline for the N1 program that is a) realistic, and b) doesn't have a POD earlier than 1966. So, because I have no actual writing skills, I created this (rather literal) timeline, and I was wondering what some of...
  9. No Space Shuttle

    I was wondering, what is the alternative for NASA, if they do not go for Space Shuttle in the post-Apollo era? The STS seems like a good idea on paper, but with the benefit of hindsight many of its flaws are obvious, and could NASA instead go with more "classical" expendable rockets and...
  10. No NASA: US Military in control of American program

    What if Eisenhower (or another potus, same period) doesn't direct that the main US program be civilian run? How successful would the Air-Force/ Navy space programs be?

    Reactions to a Soviet Moon Landing

    Let us suppose that the Soviet Union, for a POD of your preference (Sergei Korolev does not die? Vasily Mishin is not chosen as his successor? The URSS take the Space race more seriously from the beginning? Choose the one you like more) manages to beat the United States to the moon, forever...
  12. What if NASA HQ went to Hampton Roads/Norfolk instead of Houston?

    So, I got to do the headline story for the Virginia Gazette and Daily Press for the 50th Anniversary of Apollo 11 landing on the moon... and I came upon a DOOZIE of a what if a lot of folks have been overlooking about early NASA history. Specifically, a lot of folks I spoke with talked about...

    Apollo 13 fails while in Lunar orbit?

    Heres an interesting question; what if the oxygen tanks weren't stirred until after the CSM/LEM had entered Lunar orbit? There are two scenarios here: Scenario 1: The CSM explodes before the landing is attempted. This one is fairly simple and boils down to whether or not the LEM had enough ∆V...
  14. AHC/PC: X-15 carries the first human in space

    Plausibility check: X-15 being the first spacecraft to carry human in space, preferably in 1960-1961.
  15. WI: A Space Shuttle Post-Columbia Accident Suffers Heatshield Damage

    So I believe the post-Columbia procedure for all flights but the two Hubble Missions was to essentially abort to the ISS if heatshield damage was detected. What I'm curious about is what would happen to the orbiter and astronauts in such a scenario. Would they keep the orbiter attached to the...
  16. AHQ: Would USS Lake Champlain be still the prime recovery ship had Freedom 7 went up earlier?

    Would USS Lake Champlain be still the prime recovery ship had Freedom 7 went up earlier on March 24?
  17. AHC: Put humans on Mars by this year

    No ASB, and keep the POD after 1900. By the end, have humans walking on Mars by the year 2019. They don’t have to stay long, just a quick walk around is fine.
  18. Earlier far-side lunar landing plans

    In wake of recent successful landing of Chang'e 4, are there any earlier plans by either the USA or Russia/USSR to land a probe or even a man on the lunar far side?

    How would the space race be under Nixon?

    If Nixon won 1960, how would the space race go? Does the US still land on the moon? Do the Soviets get there first? What year would the first lunar mission be? How does NASA develop under Nixon being the 35th President?

    Nichelle Nichols leaves Star Trek in 67

    I don't know how much truth about the Meeting between Nichelle Nichols and Martin Luthur King Jr. Really influence her to staying on Star Trek but the idea comes what if King or Nichols missed the NAACP meeting for some reason and she left the role of Lt. Uhura after the first season to go back...
