STS-1 was the first orbital flight of the Space Shuttle, launched on April 12, 1981, and returning to Earth April 14. Space Shuttle Columbia orbited the earth 37 times in this 54.5-hour mission. It was the first US manned orbital space flight since the Apollo-Soyuz Test Project on July 15, 1975. STS-1 was one of the few manned maiden test flights of a new spacecraft system, although it was the culmination of sub-orbital and atmospheric testing for the Space Shuttle program.
