    A British Space Race

    Here’s an interesting timeline idea that I whipped up in a few hours: 1966.2.19 The Americans had known that the British were up to something. Seven months earlier they had gotten reports that an some sort of secret development project was happening in England, but they didn’t know what it...
  2. WI: More countries in the International Space Station (China particulary)

    A question for the space buffs here; what if there are more countries participating in the ISS? China is barred from participating due to a US congress act in 2011, but it had previously expressed interest. Being perhaps the third or fourth largest space player right now, its participation...
  3. 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?
  4. 1984, or, the Year the Soviets blew up Congress

    15th December, 1960 A man walks silently through the cold, bitter halls of the Kremlin, fingers trembling in the cold. Inside, his mind burns with ideas, cursing the engineers who defy him, the assistants that conspire to usurp his position, his competitors in the military. Twelve days ago, he...

    AHC: A Ukrainian Moon Landing

    Here is something from October 2016: As you can guess Mr. Degtyarev statement was met with much jokes on the Eastern European side of the internet. At the same time, it isn’t as silly as it first appears as Ukraine does have a space-rocket industry (albeit one that OTL builds light/medium...

    AHC/WI: The Soviets Land On The Moon After The USA

    Your mission, if you choose to accept it, is to make it so that the Soviet Union lands on the moon after the United States in 1969, and to explain the ramifications of them doing so.

    Realistic British Interplanetary Society Moonship?

    Exactly what it says on the tin. Can a BIS Moonship conduct a manned Lunar landing before July 20th, 1969? Personally I think it’s possible, but then I am a member of BIS, so I may be a bit biased. For those of you who don’t know exactly what I’m talking about, here are some articles about the...

    How Far Can The Early 20th Century Advance With Rockets?

    What it says on the tin. Starting in 1903ish, what can a rocket program (started for whatever reason) do with a modest but steady amount of funding? What can they get done by 1910? 1920? 1930? 1940?
  10. Space Race without WWII?

    What countries would be involved in a space race assuming no WWII? I know such a POD changes everything, but let's speculate that the Nazis either don't take power in Germany or it's a short dictatorship that fizzles out. There are conflicts, but not a total war involving the world's powers. By...

    1989: A Space Timeline
    Threadmarks: I: STS-27

    This timeline can also be found on Sufficient Velocity. STS-27 Commander Howard “Skip” Johnson was the first to speak up. “We’re in deep shit.” The rest of the crew of Space Shuttle Atlantis were in agreement. On the second day of mission STS-27, December 3rd 1988, an unusual request was...
  12. DBWI: 50th Anniversary of the first moon landing!

    Front of the Time Magazine July 20 2019. Headline, in big letters, 1969! 50 YEARS SINCE WE JOINED OUR SISTER IN THE SKY! "For all of human history, we have been looking to our moon, our sister in the sky, and wondered what was up there. We all know the familiar sight of that sphere of green and...

    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. 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...
  15. AHC: Soviet space probe reaches Mercury or outer planets

    With a post-1900 PoD make the Soviet space program to successfully send a space probe to either Mercury or the outer planets.
  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.

    AHC: Largest presence in space by 2018

    So, my challenge here is rather simple, basically what it says on the tin. Here's the specific conditions: - POD in 1901 or later - I'm specifically looking at the total off-world population in 2018, and the number of nations with space colonies - Mäps give extra points, either of Earth or of...

    A/N: This is my first attempt at a serious timeline. All comments, suggestions, and critiques are welcome. Chapter 1: It was the spring of 1955, and planning for the upcoming International Geophysical Year was in full swing. President Eisenhower had just ordered the formation of a committee to...

    Threadmarks: Teaser

    NASA's Waterloo October 2, 1983 Kennedy Space Center A crowd had gathered at Kennedy Space Center, larger than any seen since 1969. They cheered as the countdown timer approached the final minute. Miles away, on the pad, a white and black rocket glistened on the pad. Though larger, and more...
