Hangar: rockets & spacecraft
Who wins the space race?
Pick two agencies. Only facts verified on each agency's own pages, with source links. Every agency has strengths, so you decide the winner.
Build your mission
A simplified game: real figures, but real missions also depend on staging, launch site and timing.
Rocket scale
Heights from public sources, next to a ~30 m, 10-storey building.
Ship builder
Engineering tip: real rockets put fins at the back so the centre of pressure sits behind the centre of mass, which keeps the flight stable.

Your AI crew
Three holographic crew bots. Pick one to get a guide tip, a hint, or a quick quiz. Each quiz answer links its source.
Rank & certificate
