"Skylab, a science and engineering laboratory, was launched into Earth orbit by a Saturn V rocket on 14 May 1973. Three crews of 3 men each visited the station, with their missions lasting 28, 59, and 84 days......There were a plethora of UV astronomy experiments done during the Skylab lifetime, as well as detailed X-ray studies of the Sun."
Skylab fell from orbit on 11 July 1979.
