In 1973 and 1974, three Apollo missions flew on Saturn IB launchers to Skylab, the United States’ first space station in Earth orbit. Skylab was a converted S-IVB stage and was launched by a Saturn V on May 14, 1973. These flights provided invaluable science on Earth observations and on the effects of long-term weightlessness on human physiology, setting endurance records (28, 59 and 84 days) for their crews:

– Skylab 2 (May 25, 1973 - June 11, 1973): Pete Conrad, Paul Weitz, Joe Kerwin.

– Skylab 3 (July 28, 1973 - September 25, 1973): Alan Bean, Jack Lousma, Owen Garriott.

– Skylab 4 (November 16, 1973 - February 8, 1974): Gerald Carr, William Pogue, Ed Gibson.
