Three locations in the United States were used as landing sites for the Space Shuttle system. Each site included runways of sufficient length 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.[1] 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.
