Starting with Columbia and continuing with Challenger, Discovery, Endeavour, and Atlantis, the shuttle has carried people into orbit repeatedly, and launched, recovered and repaired satellites. The final space shuttle mission, STS-135, ended July 21, 2011 when Atlantis rolled to a stop at its home port, NASA's Kennedy Space Center in Florida. A sixth shuttle, Enterprise, was used for testing, but never flew in space. Two shuttles failed and crashed in flight, but the remaining four shuttles are on display at public viewing sites around the country. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/Space_Shuttle/Space_Shuttle.dc.xml Thu, 01 Jan 1970 12:00:00 GMT
