STS-7 was the second flight of Space Shuttle Challenger and NASA's first five-person Shuttle crew. Launched from Kennedy Space Center's Launch Complex 39A on June 18, 1983, the mission was commanded by Robert Crippen with Frederick Hauck as pilot and Sally Ride, John Fabian, and Norman Thagard as mission specialists. Ride became the first American woman to fly in space. The crew deployed the Anik C-2 and Palapa B1 communications satellites, operated the Canadian-built Remote Manipulator System with the Shuttle Pallet Satellite, and supported a range of science and technology experiments. Challenger landed at Edwards Air Force Base on June 24, 1983, after a mission lasting a little over six days.
