Progress M-15 was a Russian unmanned cargo spacecraft which was launched in 1992 to resupply the Mir space station. The thirty-third of sixty-four Progress spacecraft to visit Mir, it used the Progress-M 11F615A55 configuration, and had the serial number 215. It carried supplies including food, water and oxygen for the EO-12 crew aboard Mir, as well as equipment for conducting scientific research, and fuel for adjusting the station's orbit and performing manoeuvres. It also transported the Mak 2 satellite, which was deployed from Mir on 20 November.
Progress M-15 was launched at 17:19:41 GMT on 27 October 1992, atop a Soyuz-U2 carrier rocket flying from Site 31/6 at the Baikonur Cosmodrome. Following two days of free flight, it docked with the aft port of the Kvant-1 module at 17:19:41 GMT on 29 October.
During the 97 days for which Progress M-15 was docked, Mir was in an orbit of around 396 by 399 kilometres (214 by 215 nmi), inclined at 51.6 degrees. Progress M-15 undocked from Mir at 00:44:53 GMT on 4 February 1993, however it remained in orbit to conduct the Znamya 2 experiment, and research into autonomous flight. It was deorbited on 7 February, and burned up during reentry over the Pacific Ocean at around 08:03:35 GMT.
