Mission Highlights

The Challenger's second flight began at 7:33 a.m. EST, June 18, 1983, with another on-time liftoff. It was the first flight of an American woman in space -- Sally K. Ride -- and also the largest crew to fly in a single spacecraft up to that time, five persons.

Crew members included Robert L. Crippen, commander, making his second Shuttle flight; Frederick C. Hauck, pilot; Ride, John M. Fabian and Norman Thagard, all mission specialists. Thagard conducted medical tests of the Space Adaptation Syndrome nausea and sickness frequently experienced by astronauts during the early phase of a space flight.

Two communications satellites -- Anik C-2 for Telesat of Canada, and Palapa B-l for Indonesia -- were successfully deployed during the first 2 days of the mission. The mission also carried the first Shuttle Pallet Satellite (SPAS-l) built by Messerschmitt-Bolkow-Blohm, a West German aerospace firm. SPAS-l was unique in that it was designed to operate in the payload bay or be deployed by the RMS as a free-flying satellite. It carried 10 experiments to study formation of metal alloys in microgravity, the operation of heat pipes, instruments for remote sensing observations, and a mass spectrometer to identify various gases in the payload bay. It was deployed by the RMS and flew alongside and over Challenger for several hours while a U.S.-supplied camera took pictures from the SPAS-1 of the orbiter performing various maneuvers. The RMS later grappled the pallet and returned it to the payload bay.

This mission also carried seven GAS canisters which contained a wide variety of experiments, as well as the OSTA-2 payload, a joint U.S.-West German scientific pallet payload. Finally, the orbiter's Ku-band antenna was able to relay data through the Tracking and Data Relay Satellite to a ground terminal for the first time.

STS-7 was scheduled to make the first Shuttle landing at the Kennedy Space Center's Shuttle Landing Facility. However, unacceptable weather forced a change to Runway 23 at Edwards AFB. The landing took place June 24, 1983, at 6:57 a.m. PDT. The mission lasted 6 days, 2 hours, 23 minutes, 59 seconds. It covered about 2.2 million miles during 97 orbits of the Earth. Challenger was returned to KSC on June 29.
