*'''Skylab''' was America's first space station and orbital science and engineering laboratory.  Skylab was launched into Earth orbit by a Saturn V rocket on May 14, 1973 as part of the Apollo program. Three crews visited the station, with their missions lasting 28, 59 and 84 days.  The mission crews performed a plethora of UV astronomy experiments, eight separate solar experiments and detailed X-ray studies of the Sun. <ref> http://www.nasa.gov/mission_pages/skylab/index.html </ref>

The program also led to new technologies. Special showers, toilets, sleeping bags, exercise equipment and kitchen facilities were designed to function in microgravity. <ref> http://www.nasa.gov/mission_pages/skylab/index.html </ref> <ref> http://www.nasa.gov/missions/shuttle/f_skylab1.html </ref>
