ChallengerSpace Shuttle Challenger lifts off on the first mission to retrieve a satellite in orbit, repair it, and release it back into that orbit. Launched in 1980, prior to the first shuttle mission, the Solar Maximum (Solar Max) Satellite is outfitted with a mechanism to allow the shuttle’s remote manipulator arm to grasp it; however, two astronauts using Manned Maneuvering Units still have to nudge it into Challenger’s cargo bay. With repairs completed, Solar Max is returned to its orbit, where it lasts until 1989. Challenger’s crew on this flight consists of Commander Bob Crippen, Pilot Francis Scobee, and mission specialists Geroge Nelson, James Van Hoften and Terry Hart.
