Earth observations taken from shuttle orbiter Columbia during STS-87 mission
Summary
STS087-703-089 (19 November – 5 December 1997) --- Featured in this view is center pivot irrigation in central Saudi Arabia. Abundant petroleum has provided the energy source for deep-well pumps that tap groundwater stored in bedrock many thousands of years ago when the climate was much wetter. The fields are carved out of ancient alluvial fan deposits, also formed when rainfall was much greater; the fields are pushed right to the edge of the Nafud al Mazhur (sand sea), representative of the present climate. The mining of petroleum and groundwater has enabled Saudi Arabia to become an exporter of wheat and other commodities, in addition to the oil for which it is famous. This picture is one of the 70mm Earth observation visuals used by the crew at its post flight presentation events.
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.
