For All Mankind is exploring the idea of never ending space race if Soviets would have beaten US in the race for the Moon and the intention of the show is each season to jump about a decade further into the increasingly diverging reality of the show: in season 1, depicting alternate 1969 to 1974, both Soviets and US start building their separate bases near the lunar South pole; in season 2 (1983) both bases have been expanded and the superpowers compete for resources on the Lunar surface; in season 3 (1992 to 1995), Soviets and US are joined by a private company Helios and North Korea for a four way race to establish the first human base on Mars. Season 4 will start airing on November 10 on Apple TV+ and will depict the alternate 2003.
