Earth observations taken from shuttle orbiter Atlantis during STS-84 mission
Summary
STS084-710-098 (15-24 May 1997) --- A rare view of the Great Lakes captured in one frame. The Great Lakes region is home to 8.5 million Canadians and 32.5 million Americans. At center is Lake Huron and Georgian Bay. Above Lake Huron and towards the horizon is Lake Michigan, the only Great Lake to be located entirely within the United States. To the right of Lake Michigan, and partially under clouds, is Lake Superior the second largest lake in the world after the Caspian Sea. Lake Erie is located to the left of Lake Huron. Next to Lake Erie is Lake Ontario. According to geologists, the Great Lakes were created by glacial processes that began about 1,000,000 years ago.
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.
