    And Now, For Something A Little Different: The Jupiter Timeline
    Threadmarks: Chapter 0: A Goldmine

    Hey all. I have recently been motivated and inspired to finally get around to writing that space story I've always wanted to write. Between rediscovering an old rocket (and subsequently realizing I quite enjoyed its looks), and being frustrated with the now impossibility of a 2024 lunar return...

    (quick word of warning, i have literally never posted to this forum before so if i've done anything wrong, please let me know, thanks!) (also, big thanks to RaptorNM for getting me into this, i'll be running this thread alongside his) The year is 1965. After a successful streak of dominance...
  3. One Giant Leap: The Voyage Beyond

    Happy Monday Everyone! Today I want to bring you the first chapter in my alternate history story, "One Giant Leap: The Voyage Beyond". A story inspired by my thoughts of a Space Shuttle program that returned us to the moon and took us to Mars. I have often seen alternate history stories that...

    JAXA+ | What if Japan had an unlimited space budget? | 2048-12-20 - Massive crewed missions to Venus, Mars, the Moon, and the asteroid belt! [VIDEO]
    Threadmarks: 202X - Intro and H-Z rocket

    In response to the Japanese economy and space program losing its ambitions in almost every modern timeline, an alien space bat decided to give the Japan Aerospace Exploration Agency (JAXA) an unlimited budget and resources for space development. The agency thus became known as JAXA+. The early...

    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...

    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: The British Land On The Moon

    Your challenge, if you choose to accept it, is to make it so that British Astronauts land on the moon, and explain the ramifications of such a landing.

    Lunar biomes

    See this map, this is the go to map for most people looking for a map of a terraformed moon. This is probably not the most accurate map out there, but that's not important, what is important is our intentions. What I hope to accomplish with this thread is to create a "realistic" biome map of the...

  11. Alternate Apollo 11 Crew

    Is it possible that Apollo 11 could've had a different crew? If so, who are the most likely to replace Neil Armstrong and Buzz Aldrin as the first men on the moon?

    Challenge: African or Afro-American/Afro-Caribbean astronaut the first man/woman on the Moon

    What is the earliest possible date, in a 20th century with closely similar technological progression of spaceflight as in OTL, that the first man on the Moon ends up being an African-American citizen of the US, or a person of Afro-Caribbean descent, or a person born directly in an African...
  13. 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?
  14. Base Maps of our Solar System

    Are there any good base maps for various places in our beautiful solar system? It would be great to have good maps of Ceres, Ganymede, Mercury, Pluto and other planets, dwarf planets and moons of our solar system. If there isn't already a place to share maps of our solar system, it would be nice...

    I decided to create this thread because I like planets, space and the Universe, and think that some people might like it too. You can create and put here the planets, stars, nebulae, galaxies and other astronomical objects. Also you can invent civilizations, spaceships, etc.

    How spaceflight works 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...

    What it says on the tin, with a POD between 1900 and 1920, can you have a space race involving multiple parties (Nations or otherwise) Bonus points for- (the race spanning from 1950s to 1990s and ending with a landing on mars.) (the highest number of players)

    Launching a new timeline here (hope the name isn't taken). I'll answer questions here and there as they come, but I'm hoping to tell the story, for the most part, through a series of short stories and let internal context clues do a good chunk of the heavy lifting. Still, I'll try not to leave...

    DBWI: Americans landing on the Moon.

    As you probably know, the 50th and 60th years are considered an era of Soviet domination in the exploration of outer space. In particular, three events are most memorable: the launch of an artificial satellite, the flight of Yuri Alekseevich Gagarin and the first lunar expedition of Alexei...
