STS-32 was the 33rd launch of the Space Shuttle and the 9th launch of Space Shuttle Columbia. It marked the first time Pad A at Kennedy Space Center's Complex 39 was used for a launch since the 61-C mission on January 12, 1986. It was also the first use of Mobile Launcher Platform No. 3 (MLP-3) in the Space Shuttle program, and one of the longest Shuttle missions at 10 days. Before STS-32, the only mission of the same duration had been STS-9 in 1983, which was the first Spacelab mission and also on Columbia. STS-32 executed the third night landing and fourth night launch of the program, and the second night launch since Shuttle flights resumed in 1988.

[edit] Facility preparations
Pad A was modified in preparation for the launch. NASA made improvements to the crew emergency egress system and in the payload changeout room, increased protection against freezing of the water services, installed debris traps used during propellant loading, and added more weather protection features and an umbilical to provide power, instrumentation and controls to the heaters for the solid rocket booster field joints.
MLP-3, the oldest of the three Apollo-era launch structures, also underwent extensive remodeling for use with the Shuttle. Those modifications included removal of the umbilical tower, reconfiguring for three exhaust holes, and changing the electrical and mechanical ground support systems.
[edit] Mission highlights
January 9, 1990, 7:35:00 a.m. EST. The launch was first scheduled for December 18, 1989, but was later postponed to complete and verify modifications to Pad A. The second scheduled launch on January 8, 1990 was aborted due to weather conditions. Launch Weight: 255,994 lb (116.117 Mg).
The objectives of the mission were to deploy the SYNCOM IV-F5 (also known as LEASAT 5) defense communications satellite and retrieve NASA's Long Duration Exposure Facility (LDEF), whose retrieval had been delayed for 4 1/2 years by scheduling changes and an accident on 51-L. The SYNCOM IV-F5 deployed first, and a third stage Minuteman solid perigee kick motor propelled it into a geosynchronous orbit. Dunbar retrieved the LDEF on day four of the flight using the remote manipulator system. The timeliness of the retrieval had been of critical importance, because a high rate of solar flux had increased the density of the LDEF's orbital environment and accelerated its rate of orbital decay. Specialists who carefully monitored the stability of the craft's orbit had anticipated that if the LDEF was not retrieved in time, it could fall back into Earth's gravity pull and be destroyed during re-entry in February 1990.
Ivins photographed the free-flying structure which held 57 science, technology and applications experiments. The 12-sided cylinder, about the size of a small bus, was then berthed in the orbiter's payload bay for return to Earth.
NASA had planned to acquire data on the crew members' exposure to long periods of zero gravity and its effects on landing the orbiter during the extended mission. An orbiter kit was developed to allow the orbiter to operate up to 16 days in Earth orbit.
The mission's exact liftoff time was determined about 12 hours before launch, using the latest tracking data on LDEF. It was flown on a 219 statute mile (352 km) orbit inclined 28.5 degrees to the equator.
The Shuttle landed on January 20, 1990 at 1:35:37 a.m. PST on Runway 22 of Edwards Air Force Base in California with a landing weight of 228,335 lb (103,571 kg). The rollout distance was 10,731 feet (3,271 m) and rollout time was 62 seconds. The orbiter returned to KSC on January 26, 1990.
