Progress M-18 (Russian: Прогресс М-18) was a Russian cargo uncrewed spacecraft which was launched in 1993 to resupply the Mir space station.[2] The thirty-sixth of sixty four Progress spacecraft to visit Mir, it used the Progress-M 11F615A55 configuration,[3] and had the serial number 218.[4] It carried supplies including food, water and oxygen for the crew aboard Mir, as well as equipment for conducting scientific research, and fuel for adjusting the station's orbit and performing manoeuvres.
Progress M-18 was launched at 06:41:47 GMT on 22 May 1993, atop a Soyuz-U2 carrier rocket flying from Site 1/5 at the Baikonur Cosmodrome.[4] It was the last Progress spacecraft to be launched on a Soyuz-U2. Following two days of free flight, it docked with the Forward port of Mir's core module at 08:24:44 GMT on 24 May.[5][6]
During the 40 days for which Progress M-18 was docked, Mir was in an orbit of around 388 by 390 kilometres (210 by 211 nmi), inclined at 51.6 degrees.[1] Progress M-18 undocked from Mir at 15:58:16 GMT on 3 July; less than half an hour before Soyuz TM-17 docked with the port which it had vacated. It was deorbited around a day later, to a destructive reentry over the Pacific Ocean.[1][5] Before undocking, a VBK-Raduga capsule launched aboard Progress M-17 had been installed on Progress M-18, and this separated once the deorbit burn was complete. The capsule landed successfully at 17:13 GMT.[5]
