Here’s an interesting illustration showing the size comparison of a Space Shuttle to a Soyuz vehicle, shared on Twitter by NASA astronaut Rick Mastracchio (@AstroRM). Amazing to think that three flight-suited astronauts are able to fit inside a Soyuz and have life support for up to a month! (Although I’m sure most hope they won’t have to stay that long.)

Compare the 7-person capacity, 65.8 cubic meter crew cabin of an orbiter to the 3-person, 10 cubic meter space inside a Soyuz and one can imagine how cozy it must get during trips to and from the Station.

Rick is currently in training for a Soyuz flight to the ISS in November of next year as a member of the Expedition 38 crew, at which time he’ll get plenty of first-hand experience with the precise interior measurements of a Soyuz.

Thanks to Rick for sharing this! You can find out more about the Soyuz vehicles here, and check out the full source publication MIR Hardware Heritage (1995) by David S. F. Portree for Johnson Space Center.
