Progress M-31 (Russian: Прогресс M-31) was a Russian unmanned Progress cargo spacecraft, which was launched in May 1996 to resupply the Mir space station.


Progress M-31 launched on 5 May 1996 from the Baikonur Cosmodrome in Kazakhstan. It used a Soyuz-U rocket.[2][5]


Progress M-31 docked with the forward port of the Mir Core Module on 7 May 1996 at 08:54:19 UTC, and was undocked on 1 August 1996 at 16:44:54 UTC.[3][4]


It remained in orbit until 1 August 1996, when it was deorbited. The deorbit burn occurred at 19:44:30 UTC and the mission ended at 20:33:03 UTC.[3][4]
