Just after sundown, Space Shuttle Discovery is framed with light from the Fixed Service Structure on Launch Pad 39B as it waits for liftoff on mission STS-103. At the top is seen the external tank gaseous oxygen vent arm system with the vent hood (commonly called the "beanie cap") poised above the external tank. The retractable arm and the beanie cap are designed to vent gaseous oxygen vapors away from the Space Shuttle. The arm truss section is 65 feet long and the diameter of the beanie cap is 13 feet. Extending toward the cabin of the orbiter is the orbiter access arm, with the environmental chamber (called the White Room) at the end. Through this chamber the crew enters the orbiter. The STS-103 mission, to service the Hubble Space Telescope, is scheduled for launch Dec. 17 at 8:47 p.m. EST. Mission objectives include replacing gyroscopes and an old computer, installing another solid state recorder, and replacing damaged insulation in the telescope. The mission is expected to last about 8 days and 21 hours. Discovery is expected to land at KSC Sunday, Dec. 26, at about 6:25 p.m. EST KSC-99padig045

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.
