Progress 27 (Russian: Прогресс 27) was a Soviet uncrewed Progress cargo spacecraft, which was launched in January 1987 to resupply the Mir space station.


Progress 27 launched on 16 January 1987 from the Baikonur Cosmodrome in the Kazakh SSR. It used a Soyuz-U2 rocket.[2][4]


Progress 27 docked with the aft port of the Mir Core Module on 18 January 1987 at 07:26:50 UTC, and was undocked on 23 February 1987 at 11:29:01 UTC.[3][5]
