Progress 7 (Russian: Прогресс 7) was a Soviet unmanned Progress cargo spacecraft, which was launched in June 1979 to resupply the Salyut 6 space station.


Progress 7 launched on 28 June 1979 from the Baikonur Cosmodrome in the Kazakh SSR. It used a Soyuz-U rocket.[2][4]


Progress 7 docked with the aft port of Salyut 6 on 30 June 1979 at 11:18:32 UTC, and was undocked on 18 July 1979 at 03:49:55 UTC.[3][5]


It remained in orbit until 20 July 1979, when it was deorbited. The deorbit burn occurred at 01:57:30 UTC and the mission ended at 02:40 UTC.[3][5]
