| | Skylab |
 | | Launch of the unoccupied Skylab, designated Skylab 1 (the occupied missions were officially designated Skylabs 2, 3 and 4, but are generally referred to as Skylabs I, II and III, and are referred to in that manner here) took place on May 14, 1973, and problems set in early on. |
 | | The first crew, Skylab I, which was supposed to launch the next day, was delayed for ten days while mission personnel devised a method to repair the crippled station. |
 | | Skylab's orbit slowly deteriorated and it finally burned up in the atmosphere on July 11, 1979, more than five years after the last crew left for home. |
