I'm in the process of writing an article for the American Numismatic Association (ANA) about (for the most part) space flown coins, medallions etc. One of the things I'm trying to get across is just how small the habitable space was for humans aboard the Mercury, Gemini and Apollo spacecraft. I've found data that agrees with my recollection that the Apollo command module had roughly 210 cubic feet of habitable space and the lunar module had roughly 160 cubic feet.

Unfortunately I can't find data for the habitable space for the Gemini capsule, and the space I'm currently seeing for Mercury is 100 cu. ft., which seems much too large. From what I remember it was about 45 cu. ft. and Gemini was about 80 cu. ft.

Does anyone know what the habitable space was for either (or both) the Mercury or Gemini spacecraft? While we're at it, does anyone know what the habitable space aboard the space shuttle was (not including add-ons such as Spacelab etc.). Thank you very much!

  • Mercury: 1.02 cubic m (36 cubic ft)
  • Gemini: 1.56 cubic m (55 cubic ft)
But Gemini, with two crew, had less room per person. (Source)

It would be interesting to see what the habitable volume of Gemini would be after subtracting the volume of two, space-suited astronauts.

A five-man Skylab Rescue mission command module would have had more room per person than the Gemini spacecraft.
