Overview
During this flight, Challenger deployed two communications satellites for Western Union and Indonesia, and McCandless became the first person to perform a free-flying, untethered spacewalk. Challenger conducted the first Space Shuttle landing at the Kennedy Space Center and was the first Shuttle flight to use the new numbering scheme. Since the Shuttle was supposed to launch from both Florida and California, NASA switched to STS-41-B numbering scheme where the first number after "STS-" was the fiscal year of the program the mission was to fly in; the second number was either a "1" for Kennedy or a "2" for Vandenberg Air Force Base, California; and the "-letter" was the order the missions for a particular fiscal year and launch site were originally planned in. Thus, STS-41-B was the second planned launch from the Kennedy Space Center in the fourth year of the program.

The first reusable launch and landing spacecraft, the Space Shuttle began a new chapter of human space exploration. It launched like a rocket but landed on a runway like a plane. Shuttle crews deployed dozens of commercial satellites and two interplanetary probes to Venus and Jupiter. The Shuttle served as a mini space station and hosted hundreds of biomedical, psychological, physiological, materials science, and physics experiments that have directly benefited life on Earth. The five flight-worthy Shuttles -- Columbia, Challenger, Discovery, Atlantis, and Endeavour -- flew 135 missions over 30 years. The Shuttles helped construct the Russian Mir space station and brought nearly 80% of the International Space Station to orbit. Shuttles also deployed and serviced the Hubble Space Telescope.
