Shuttle astronauts are shown changing the lithium hydroxide canisters which purify the air in the flight deck and living quarters, the only presurised but still weightles part of the craft. The Space Shuttle, the world's first partially reusable launch vehicle, first flew on 12th April 1981 and has been used for all America's manned space misions ever since. It normally carries a crew of five to seven and can lift a payload of some 25,000kg into low Earth orbit.
