Space Shuttle Challenger (OV-099) lifted off from Launch Complex 39A at the Kennedy Space Center, Cape Canaveral, Florida, on mission STS-7.
This was Challenger‘s second flight, and it carried a five-person crew, the largest aboard a single spacecraft up to that time. Commanded by Robert L. Crippen on his second shuttle flight, STS-7 was to place two communications satellites in orbit and to deploy an experimental pallet with multiple experiments.
Aboard was Mission Specialist Sally Kristen Ride, Ph.D., America’s first woman to fly in space. She operated the Shuttle Remote Manipulator System, a robotic arm, to deploy and retrieve satellites.
