Space travelers have spent by 2007 over 29,000 person-days (or a cumulative total of over 77 years) in space including over 100 person-days of spacewalks. [51] Usual durations for individuals to inhabit space on long-duration stays are six months, [52] with the longest stays on record being at about a year.
The interior of the Apollo PLSS Diagram of the A7L PLSS and OPS, with interfaces to the astronaut and the Lunar Module cabin. The portable life support system used in the Apollo lunar landing missions used lithium hydroxide to remove the carbon dioxide from the breathing air, and circulated water in an open loop through a liquid-cooled garment, expelling the water into space, where it turned ...
