STS-1 was the first Space Shuttle mission. It was launched on 12 April 1981, and returned 14 April. Space Shuttle Columbia orbited the earth 36 times in this 54.5 hour mission. It was the first US manned space flight since the Apollo-Soyuz Test Project in July 1975.

Launch occurred on April 12, 1981, when the orbiter Columbia, with two crew members, astronauts John W. Young, commander, and Robert L. Crippen, pilot, lifted off from Pad A, Launch Complex 39, at the Kennedy Space Center -- the first of 24 consecutive launches from Pad A. It was exactly 7 a.m. EST. A launch attempt, 2 days before, was scrubbed because of a timing problem in one of the Columbia's general purpose computers.

Not only was this the first launch of the Space Shuttle, but it marked the first time that solid fuel rockets were used for a U.S. manned launch. It was also the first US manned space vehicle launched without an unmanned powered test flight. The STS-1 orbiter, Columbia, also holds the record for the amount of time spent in the Orbiter Processing Facility (OPF) before launch -- 610 days, time needed for replacement of many of its heat shield tiles.

Primary mission objectives of the maiden flight were to check out the overall Shuttle system, accomplish a safe ascent into orbit and to return to Earth for a safe landing. All of these objectives were met successfully and the Shuttle's worthiness as a space vehicle was verified. ( more...)
