Progress M-12 was launched at 21:29:25 GMT on 19 April 1992, atop a Soyuz-U2 carrier rocket flying from Site 1/5 at the Baikonur Cosmodrome.[4] Following two days of free flight, it docked with the Forward port of the core module of Mir at 23:21:59 GMT on 21 April.[5][6] During the 67 days for which Progress M-12 was docked, Mir was in an orbit of around 371 by 415 kilometres (200 by 224 nmi), inclined at 51.6 degrees.[1] Progress M-12 undocked from Mir at 21:34:44 GMT on 27 June, and was deorbited few hours later, to a destructive reentry over the Pacific Ocean at around 00:02:51 the next day.[1][5]
