NASA launches Space Shuttle Columbia on the 48th shuttle mission (Columbia’s 12th trip into orbit). Using the Spacelab module, Columbia’s crew conducted the first USML (United States Microgravity Laboratory) flight, as well as testing a new system called the EDO (Extended Duration Orbiter) package, allowing the crew to stay in orbit longer than any previous shuttle (or, for that matter, lunar) flight. Aboard Columbia for the record-breaking 13-and-a-half-day mission are Commander Richard N. Richards, Pilot Ken Bowersox, Payload Commander Bonnie Dunbar, mission specialists Ellen Baker and Carl Meade, and payload specialists Lawrence DeLucasand Eugene Trinh.
