The first Space Shuttle mission, STS (Space Transportation System)-1, was launched April 12 1981, and returned April 14. Space Shuttle Columbia orbited the earth 37 times in this 54.5-hour mission. It was the first US manned space flight since the Apollo-Soyuz Test Project on July 15 1975.
All Space Shuttle flights are referenced by their sequential chronological number, prefaced by the acronym "STS", which stands for "Space Transportation System", which is the proper way to refer to the collective parts of the Space Shuttle technologies used together.

Number in parentheses indicates number of spaceflights by each individual prior to and including this mission.
The first launch of the Space Shuttle occurred on April 12, 1981, exactly 20 years after the first manned space flight, 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 launches from Pad A. It was exactly 7 a.m. EST. A launch attempt 2 days earlier 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 U.S. 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.
The STS-1 Shuttle reached an orbital altitude of 166 nautical miles.
The only payload carried on the mission was a Development Flight Instrumentation (DFI) package which contained sensors and measuring devices to record orbiter performance and the stresses that occurred during launch, ascent, orbital flight, descent and landing.
The 37-orbit, 1,074,567-mile-long flight lasted 2 days, 6 hours, 20 minutes and 53 seconds. Landing took place on Runway 23 at Edwards Air Force Base, California on April 14 at 10:21 a.m. PST. [1]
Columbia was returned to Kennedy Space Center from California on April 28 atop its 747 carrier aircraft.
STS-1 was the first test flight of what was, at the time, probably the most complex spacecraft ever built. There were numerous problems – 'anomalies' in NASA parlance – on the flight, as many systems could not be adequately tested on the ground or independently. Some of the more serious or interesting were:
Despite these problems, STS-1 was a successful test, and in most respects Columbia came through with flying colors. After some modifications to the shuttle and to the launch and re-entry procedures, Columbia would fly the next four Shuttle missions.
The artwork for the official mission insignia was designed by artist Robert McCall. It is a symbolic representation of the shuttle. The image does not depict the black wing roots present on the actual shuttle.
Yuri's Night is an international celebration held on April 12 every year to commemorate the first human in space and the first Space Shuttle launch.
In tribute to the 25th anniversary of the first flight of Space Shuttle, Firing Room 1 in the Launch Control Center at Kennedy Space Center was renamed to the Young-Crippen Firing Room, dedicating the firing room that launched the historic flight and the crew of STS-1.
NASA described the mission as: "The boldest test flight in history" [1].
STS-1 was one of only two shuttle flights to have its External Tank (ET) painted white. In an effort to reduce the Shuttle's overall weight STS-3 and all subsequent missions used an unpainted tank, which translated into a weight savings of approximately 272 kg / 600 pounds.[7] This lack of paint gives the ET its distinctive orange color now associated with the Space Shuttle.
At one stage, NASA considered making STS-1 a test of the Return to Launch Site (RTLS) abort profile, which would have required Columbia to jettison the Solid Rocket Boosters at the normal separation altitude, fly downrange and pitch the Orbiter and External Tank over, resulting in the vehicle flying backwards with all three engines burning at the same time. Because the RTLS maneuver is considered very risky, Young declined, saying, "Let's not practice Russian roulette."[8]
The song "Countdown" by Rush from the 1982 album Signals was written about STS-1 and the inaugural Space Shuttle flight of Columbia. The song was "dedicated with thanks to astronauts Young and Crippen and all the people of NASA for their inspiration and cooperation". The song "Red Sector A" from their 1984 album Grace Under Pressure was named for the area where the band witnessed the launch.
IMAX cameras filmed the launch, landing, and mission control during the flight for a film entitled Hail Columbia!, which debuted in 1982. It is now available on DVD. The title of the film comes from the pre-1930s unofficial American national anthem, also titled Hail, Columbia.
