A space station which orbited Earth in the 1970s. Performed many important observations of the Sun. more

The United States' earth-orbiting workshop that housed three crews of three men in 1973 and 1974.

Skylab was America's first orbiting space station. It was made from Saturn and Apollo equipment. Skylab was launched May 14, 1973 and orbited at an altitude of 270 miles (435 km). It orbited the Earth every 93 minutes. Three three-man crews (SL-2: Charles Conrad, Paul J. Weitz, Joseph Kerwin; SL-3: Alan L. Bean, Jack R. Lousma, Owen Garriott; SL-4: Gerald P. Carr, William R. Pogue, Edward Gibson) lived in Skylab for a total of 171 days and 13 hours; astronauts traveled to and from Skylab via Apollo spacecraft. These astronauts carried out astronomical observations and experiments on how humans react to a microgravity environment in space. Skylab re-entered the Earth's atmosphere and fell to Earth on July 11, 1979 scattering debris over the Indian Ocean and parts of Western Australia.

NASA's first orbital laboratory that was operated in 1973 and 1974.

Skylab was the first space station the United States launched into orbit. The 75 metric tonne station was in Earth orbit from 1973 to 1979, and was visited by crews three times, in 1973 and 1974. It included a laboratory for studying the effects of microgravity, and a solar observatory.
