Three locations in the United States were used as landing sites for the Space Shuttle system. Each site included runways of sufficient length to provide adequate distance for the slowing-down of a returning spacecraft. The prime landing site was the Shuttle Landing Facility at the Kennedy Space Center in Florida, a purpose-built landing strip. Landings also occurred at Edwards Air Force Base in California, and one took place at White Sands Space Harbor in New Mexico. No space shuttle landed on a dry lakebed runway after 1991.
Various international landing sites were also available in the event of a Transoceanic Abort Landing (TAL) scenario, as well as other sites in the United States and Canada in case of an East Coast Abort Landing (ECAL) situation. Space shuttle landings were intended to regularly take place at Vandenberg Air Force Base in California for Department of Defense missions launched from the site, but none occurred due to the cancellation of all launches from Vandenberg.
The Shuttle Landing Facility at the Kennedy Space Center in Florida has a single 15,000-foot (4,600 m) concrete runway, 15/33. It is designated Runway 15 or 33, depending on the direction of use. The first landing at the SLF was for mission STS-41B in 1984; landings were suspended at the site following brake damage and a blown tire during the STS-51D landing in 1985, and resumed in 1990.
Edwards Air Force Base in California was the site of the first space shuttle landing, and became a back-up site to the prime landing location, the Shuttle Landing Facility at the Kennedy Space Center. Several runways are arrayed on the dry lakebed at Rogers Dry Lake, and there are also concrete runways. Space shuttle landings on the lake bed took place on Runways 05/23, 15/33 and 17/35. Of the concrete strips, the main Runway 04/22 was utilized. During the renovation of 04/22, a temporary runway (with the same designation) was constructed parallel to it and used for one landing (STS-126). All five free flights of space shuttle Enterprise landed on Edwards Air Force Base runways.
