CAPE CANAVERAL, Fla. - After the successful Flight Readiness Firing of the space shuttle Discovery's three main engines, Kennedy Space Center Director Forrest McCartney congratulates members of the launch team in the firing room. The approximate 22-second firing was conducted to evaluate the performance of various components of the shuttle, external tank and solid rocket boosters, as well as the launch facilities and support equipment which will be used during the launch of STS-26. Looking on is Bob Sieck, KSC launch director, right, Hugh Harris, deputy director of KSC Public Affairs, left, and John Conway, director of Payload Management and Operations, second from left.

The Space Shuttle program was the United States government's manned launch vehicle program from 1981 to 2011, administered by NASA and officially beginning in 1972. The Space Shuttle system—composed of an orbiter launched with two reusable solid rocket boosters and a disposable external fuel tank— carried up to eight astronauts and up to 50,000 lb (23,000 kg) of payload into low Earth orbit (LEO). When its mission was complete, the orbiter would re-enter the Earth's atmosphere and lands as a glider. Although the concept had been explored since the late 1960s, the program formally commenced in 1972 and was the focus of NASA's manned operations after the final Apollo and Skylab flights in the mid-1970s. It started with the launch of the first shuttle Columbia on April 12, 1981, on STS-1. and finished with its last mission, STS-135 flown by Atlantis, in July 2011.
