Columbia carried the NASA/ESA Spacelab module in the cargo bay. The mission was primarily to carry out 72 scientific experiments in astronomy, physics, biology, as well as to make observations of the Earth.
Columbia landed at Edwards Air Force Base, California at 23:47:24 UTC (3:47 p.m., PST), 8 December 1983. At 10 days, 7 hours, 47 minutes, 24 seconds, STS-9 was the longest space shuttle mission up to that time.
