  1. 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?
  2. 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...

    The Stars Above: An Alternate Space Race
    Threadmarks: Chapter 1

    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...

    NASA's Waterloo: A Realistic Mission to Mars Post Apollo
    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...
  6. Who would become the first astronaut if Britain launch the first man in space

    British plan to send in man in space with a converted V-2 rocket could happen as early as 1951 if it was approved, so who would become the first astronaut in that program?

    Aozhouhuaren's Art and Shit

    Not sure where this belongs but I saw "Graphics", so here goes. A lot of the stuff I intend to post in here are snippets from a Space Opera/AH timeline I'm working on but there will be all sorts of random stuff. To start off with, one of my favourites. (Corner Infobox Text) Pictured below...
  8. In a World where the Nazis won WW2, how advanced would spaceflight be?

    OK, another argument my friend and I had together is over Spaceflight in Nazi Germany. Assuming they won ww2, how advanced would spaceflight realistically be? Since the 'modern day' of this TL is 1998 (it's for a HOI4 Mod), 20 years ahead would be modern Falcon 9s and SLS rockets. My friend...
  9. Kistling a Different Tune: Commercial Space in an Alternate Key
    Threadmarks: Post 1: Intro/Teaser

    Hello, everyone! Welcome to yet-another @e of pi spaceflight thread. This one is going to be a bit of an experiment for me--a bit more personal, and focused on a much most recent point of departure. In fact, as everything in this timeline will be happening within the era of the "modern"...

  11. Alternate Space Ports?

    What locations around the world (Earth specifically) could have plausibly become space ports? Ideally not just one off pads, but at least a few launches, in use for at least a few years, with some associated permanent jobs and infrastructure. Cape Agulhas, South Africa, southernmost point of...
  12. Morning of the Maple Leaf: A Spaceflight Timeline-in-a-Post

    Good evening, everyone! I know it's been a little while since @Polish Eagle and I finished writing Right Side Up (and we're both pleased to thank everyone who offered their votes at the Turtledoves this year). That said, I'm proud to present the following, which is something of a spiritual...
  13. The Dream Is Alive
    Threadmarks: I: Setting the Stage

    “The dreams of yesterday are the hopes of today and the reality of tomorrow.”-Robert Goddard I: Setting the Stage For NASA, the mid-1970s had represented a lessening of the activities and work that it had once been in the 1960s in the push of the Space Race. No longer was NASA constantly...
  14. AHC: Advance human spaceflight as much as possible with the earliest PoD of 1945

    How do you think would it be possible to have more space infrastructure, possibly more frequent manned space missions, or even a rotating space station, or Moon or Mars bases today with the earliest PoD of 1945? In essence in this TL, much of the hopes for a "space future" as imagined by people...
  15. WI: America takes the first images of lunar back side

    Pioneer P-1 was set to launch late September 1959, but before it could the rocket launcher without the payload exploded on pad during pre-flight tests. http://space.skyrocket.de/doc_sdat/pioneer_p1.htm Suppose in another TL where the failure never happened and P-1 was launched mere days before...
  16. WI: Building a Launch Loop in 1997--political and practical ramifications

    So I've been kicking around an idea for a timeline--it'll be ASB, as it involves scientists spotting a quasar that'll fuck the solar system up in 130 years (incidentally, it'd be nice to know how long these scientists would need to be observing it to make that determination)--involving Clinton...

    WI: Earlier Space Race

    I have off-and-on considered the idea of an earlier space race, which has manifested itself in two main iterations I wish to call The Cosmos in Their Hearts. The main problem is that I simply cannot be creative enough to imagine how the ideas I have would effect wars and borders and countries...

    DBWI: Without the Father of Interstellar Travel?

    Although mildly obscure to the modern-day folk, the major fundamentals of space travel arose due to the Exploration of Outer Space by Means of Rocket Devices ("Исследование мировых пространств реактивными приборами"), written by the Father of Space-Rocketry, Konstantin Tsiolkovsky. This work...
  19. AHC: Earliest Possible Supersonic Flight

    With no PoDs prior to 1904,* what is the earliest that an aircraft could break the sound barrier? What is the earliest that ramjet technology could be developed? And this being done, how early could TTL see the first serious** designs for a scramjet plane? *or 1895 at the earliest, if you want...
  20. A guide to spaceflight

    How spaceflight works https://www.alternatehistory.com/wiki/doku.php?id=offtopic:the_space_jockeys Spaceflight has its own rules that makes it unique. They can be obscure at times. This is kind of guide to try and make things a little clearer. Hopefully not too pedantic nor too loaded with...
