NASA Project Skylab 1 - 2 Wall Clock

NASA "National Aeronautics Space & Administration" Project Skylab 1 - 2 Wall Clock Skylab 1 - 2 "SLM-1 - SL-2" - May 25, 1973 - June 22, 1973 - 28.03 Days Pete Conrad, Joseph Kerwin, & Paul Weitz Project Skylab - 1965-1979: Skylab was the United States' first and only independently built space station. Conceived in 1965 as a workshop to be constructed in space from a spent Saturn IB upper stage, the 169,950 lb (77,088 kg) station was constructed on Earth and launched on May 14, 1973, atop the first two stages of a Saturn V, into a 235-nautical-mile (435 km) orbit inclined at 50° to the equator. Damaged during launch by the loss of its thermal protection and one electricity-generating solar panel, it was repaired to functionality by its first crew. It was occupied for a total of 171 days by 3 successive crews in 1973 and 1974. It included a laboratory for studying the effects of microgravity, and a solar observatory. NASA planned to have a Space Shuttle dock with it, and elevate Skylab to a higher safe altitude, but the Shuttle was not ready for flight before Skylab's re-entry on July 11, 1979. To save cost, NASA used one of the Saturn V rockets originally earmarked for a canceled Apollo mission to launch the Skylab. Apollo spacecraft were used for transporting astronauts to and from the station. Three three-man crews stayed aboard the station for periods of 28, 59, and 84 days. Skylab's habitable volume was 11,290 cubic feet (320 m3), which was 30.7 times bigger than that of the Apollo Command Module.
