On Apr. 6, 1984, area shuttle bus Challenger removed on its 5th flight, STS-41C. Its five-person team of Commander Robert L. “Crip” Crippen, Pilot Francis R. “Dick” Scobee, and Mission Specialists Terry J. “TJ” Hart, James D. “Ox” Van Hoften, and George D. “Pinky Nelson flew a seven-day objective that broadened the shuttle bus's abilities. They released the Long Duration Exposure Facility (LDEF), the biggest and heaviest shuttle bus payload as much as that time. They recovered, fixed, and redeployed the stopping working Solar Max satellite in an extremely complicated choreography of rendezvous and distance operations, self-governing astronaut flying of the Manned Maneuvering Unit (MMU), robotic operations, and spacewalking. The objective likewise showed the capability of the ground groups and astronauts to effectively react to unanticipated scenarios.

In February 1983, NASA revealed Crippen, Scobee, Hart, Van Hoften, and Nelson as the STS-13 team, the objective relabelled STS-41C in September 1983. Crippen, the flight's only veteran, had actually flown as the pilot for the very first shuttle bus flight STS-1 in April 1981 and at the time of the statement in training to command STS-7 in June 1983. For the other 4, all picked as astronauts in 1978, STS-41C represented their very first journey into area. The objective had 2 main goals. The release of the LDEF, handled by NASA's Langley Research Center in Hampton, Virginia, and 2nd, the retrieval, repair work, and release of the Solar Maximum Mission, Solar Max for brief, satellite, handled by NASA's Goddard Space Flight Center in Greenbelt, Maryland. A trainee experiment in the middeck took a look at the habits of 3,300 honeybees in weightlessness. Crippen and Scobee had prime duty for running the shuttle bus and carrying out the rendezvous and distance operations. Hart had main duty for releasing LDEF utilizing the Canadian-built Remote Manipulator System (RMS), the shuttle bus's robotic arm. Nelson would fly the MMU to protect Solar Max so Hart might grapple it with the RMS and put it into a Flight Support Structure (FSS) in Challenger's payload bay where Nelson and Van Hoften would carry out the repair work. A number of earlier shuttle bus flights practiced strategies and checked hardware to make STS-41C effective, consisting of the very first shuttle bus spacewalk on STS-6, the SPAS-01 rendezvous and distance operations on STS-7, the PFTA test of the RMS on STS-8, and the test flights of the MMU on STS-41B.

The LDEF included a 21,400-pound structure determining 14 by 30 feet, at the time the biggest and heaviest things introduced by the shuttle bus and managed by the RMS.
