    Lunar/Polar Urbanism: Earliest possible permanent settlement in Antarctica and on the Moon, possible best models of settlement

    Something I've been kicking around for my incoming graphics timeline (totally still happening, I know you're all positively chomping at the bit for it, it's en route, promise) is the visibility of permanent settlement on two pretty inhospitable locales: Antarctica and the Moon. Let's leave...

    Alternate first words on the Moon

    The first words spoken on the Moon are known by heart: "That's one small step for [a] man, one giant leap for mankind." In the sci-fi television series For All Mankind, the Soviet Union is the first to achieve a manned lunar landing, with their cosmonaut making a more boastful statement: "I...

    How ambitious can alternate space histories get?

    Some alternate space timelines try to be "realistic" and fit within expected economic and political limitations, being slightly more (or less) advanced in capabilities than OTL. Others push the boundaries of realism or outright break them altogether (as if an ASB intervened) to create...

    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...

    JAXA+ | What if Japan had an unlimited space budget? | 2060-02-18 - Massive crewed missions to Jupiter, Venus, Mars, and more! [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...

    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...

    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...
