STS-9 (also referred to as STS-41A and Spacelab 1) was the ninth NASA Space Shuttle mission and the sixth mission of the Space Shuttle Columbia. Launched on November 28, 1983, the ten-day mission carried the first Spacelab laboratory module into orbit, and was Columbia's last flight until STS-61-C in January 1986.
STS-9 was also the last time the original STS numbering system was used until STS-26, which was designated in the aftermath of the 1986 Challenger disaster of STS-51-L. Under the new system, STS-9 would have been designated as STS-41-A. STS-9's originally planned successor, STS-10, was cancelled due to payload issues; it was instead followed by STS-41-B.

STS-9's six-member crew, the largest of any manned space mission at the time, included John W. Young, commander, on his second shuttle flight; Brewster H. Shaw, pilot; Owen Garriott and Robert A. Parker, both mission specialists; and Byron K. Lichtenberg and Ulf Merbold, payload specialists – the first two non-NASA astronauts to fly on the Space Shuttle. Merbold, a citizen of West Germany, was the first foreign citizen to participate in a shuttle flight. Lichtenberg was a researcher at the Massachusetts Institute of Technology. Prior to STS-9, the scientist-astronaut Garriott had spent 56 days in orbit in 1973 aboard Skylab. Commanding the mission was veteran astronaut John Young, making his sixth and final flight over an 18 year career that saw him fly twice each in Gemini, Apollo, and the Shuttle, which included two journeys to the Moon and making him the most experienced space traveler to date.
The mission was devoted entirely to Spacelab 1, a joint NASA/European Space Agency (ESA) program designed to demonstrate the ability to conduct advanced scientific research in space. Both the mission specialists and payload specialists worked in the Spacelab module and coordinated their efforts with scientists at the Marshall Payload Operations Control Center (POCC), which was then located at the Johnson Space Center in Texas. Funding for Spacelab 1 was provided by the ESA.
After Columbia's return from STS-5 in November 1982, it received several modifications and changes in preparation for STS-9. Most of these changes were intended to support the Spacelab module and crew, such as the addition of a tunnel connecting the Spacelab to the orbiter's airlock, and additional provisions for the mission's six crew members, such as a galley and sleeping bunks. Columbia also received the more powerful Space Shuttle Main Engines introduced with Challenger, which were rated for 104% maximum thrust; its original main engines were later refurbished for use with Atlantis, which was still under construction at the time. Also added to the shuttle were higher capacity fuel cells and a Ku-band antenna for use with the Tracking and Data Relay Satellite (TDRS).
The mission's original launch date of October 29, 1983 was scrubbed due to concerns with the exhaust nozzle on the right solid rocket booster (SRB). For the first time in the history of the shuttle program, the shuttle stack was rolled back to the Vehicle Assembly Building (VAB), where it was destacked and the orbiter returned to the Orbiter Processing Facility, while the suspect booster underwent repairs. The shuttle was restacked and returned to the launch pad on November 8, 1983.
STS-9 launched successfully from Kennedy Space Center at 11 am EST on November 28, 1983.
The shuttle's crew was divided into two teams, each working 12-hour shifts for the duration of the mission. Young, Parker and Merbold formed the Red Team, while Shaw, Garriott and Lichtenberg made up the Blue Team. Usually, Young and Shaw were assigned to the flight deck, while the mission and payload specialists worked inside the Spacelab.
Over the course of the mission, 72 scientific experiments were carried out, spanning the fields of atmospheric and plasma physics, astronomy, solar physics, material sciences, technology, astrobiology and Earth observations. The Spacelab effort went so well that the mission was extended an additional day to 10 days, making it the longest-duration shuttle flight at that time. In addition, Garriott made the first ham radio transmissions by an amateur radio operator in space during the flight. This led to many further space flights incorporating amateur radio as an educational and back-up communications tool.
The Spacelab 1 mission was highly successful, proving the feasibility of the concept of carrying out complex experiments in space using non-NASA persons trained as payload specialists in collaboration with a POCC. Moreover, the TDRS-1 satellite, now fully operational, was able to relay significant amounts of data through its ground terminal to the POCC.
During orbiter orientation, four hours before re-entry, one of the flight control computers crashed when the RCS thrusters were fired. A few minutes later, a second crashed in a similar fashion, but was successfully rebooted. Young delayed the landing, letting the orbiter drift. He later testified: "Had we then activated the Backup Flight Software, loss of vehicle and crew would have resulted." Post-flight analysis revealed the GPCs failed when the RCS thruster motion knocked a piece of solder loose and shorted out the CPU board.
Columbia landed on Runway 17 at Edwards Air Force Base on December 8, 1983, at 3:47 pm PST, having completed 166 orbits and travelled 4.3 million miles (6.9×106 km) over the course of its mission. Right before landing, two of the orbiter's three auxiliary power units caught fire due to a hydrazine leak, but the orbiter nonetheless landed successfully. Columbia was ferried back to KSC on December 15. The leak was later discovered after it had burned itself out and caused major damage to the compartment. The shuttle was then sent off for an extensive renovation and upgrade program to bring it up to date with the newer Challenger orbiter as well as the upcoming Discovery and Atlantis. As a result, Columbia would not fly at all during 1984-85.

The mission's main payload, Spacelab 1, is depicted in the payload bay of the Columbia. The nine stars and the path of the orbiter indicate the flight's numerical designation, STS-9.
