Scenes from Space #29

Skylab was the first space station put into orbit by the United States. The station weighed 75 metric tons, and was in orbit from 1973 until 1979. Unfortunately, the station was only manned for 171 days out of its 2249 days in orbit. One interesting this about Skylab is that it was actually the refitted second stage of a Saturn IB booster rocket, leftover from the Apollo program.
