Skylab was the first US space station, it was launched into a 435 km (270 miles) altitude orbit on May 14, 1973 as part of the Apollo program.

This 91 ton, 36 meters (4-story) high, 6.7 meters in diameter structure carried three different Apollo crews manned Skylab during its 9 month mission conducting medical experiments, solar observations and detailed Earth resources mapping experiments. Skylab spacecraft reentered the atmosphere on July 11, 1979 scattering debris over the Indian Ocean and the sparsely settled region of Western Australia.
