CAPE CANAVERAL, Fla. – At the Shuttle Landing Facility at NASA's Kennedy Space Center in Florida, NASA's GOES-P meteorological satellite is moved to the edge of the cargo bay of a U.S. Air Force C-17 aircraft for offloading. GOES-P, the latest Geostationary Operational Environmental Satellite, was developed by NASA for the National Oceanic and Atmospheric Administration, or NOAA. GOES-P is designed to watch for storm development and observed current weather conditions on Earth. Launch of GOES-P is targeted for no earlier than Feb. 25, 2010, from Launch Complex 37 aboard a United Launch Alliance Delta IV rocket.

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.
