A NASA space station, launched on 1973 May 14. The converted upper stage of a Saturn V rocket, it consisted of living quarters, a work section, and the Apollo Telescope Mount (ATM) which contained six telescopes for observing the Sun's chromosphere and corona at X-ray, ultraviolet, and visible wavelengths. Three crews, each of three astronauts, spent respectively 28 days, 59 days, and 84 days aboard the space station. Skylab was then abandoned, and re-entered in 1979 July; fragments of it fell in Western Australia.
