It carried supplies including food, water and oxygen for the EO-8 crew aboard Mir, as well as equipment for conducting scientific research, and fuel for adjusting the station's orbit and performing manoeuvres.

At 10:12:00 GMT on 26 March, the Soyuz TM-11 spacecraft which had been occupying this port undocked from it, before flying around the station and docking with Kvant-1 at 10:58:59. Progress M-7 successfully docked with Mir at 12:02:28 GMT on 28 March. During the 39 days for which Progress M-7 was docked, Mir was in an orbit of around , inclined at 51.6 degrees. Progress M-7 undocked from Mir at 22:59:36 GMT on 6 May, and was deorbited at 16:24:00 the next day, to a destructive reentry over the Pacific Ocean. Its Raduga capsule, which had been deployed following the deorbit burn, came down in the Russian Soviet Federative Socialist Republic at around 17:20 GMT; however, efforts to recover it were unsuccessful. ==See also== 1991 in spaceflight List of Progress flights List of uncrewed spaceflights to Mir ==References==",
