Progress M-9 (Russian: Прогресс М-9|italic=yes) was a Soviet uncrewed cargo spacecraft which was launched in 1991 to resupply the Mir space station.[1] The twenty-seventh of sixty four Progress spacecraft to visit Mir, it used the Progress-M 11F615A55 configuration,[2] and had the serial number 210.[3] It carried supplies including food, water and oxygen for the EO-9 crew aboard Mir, as well as equipment for conducting scientific research, and fuel for adjusting the station's orbit and performing manoeuvres. It was the third Progress spacecraft to carry a VBK-Raduga capsule, which was used to return equipment and experiment results to Earth.
Progress M-9 was launched at 22:54:10 GMT on 20 August 1991, atop a Soyuz-U2 carrier rocket flying from Site 1/5 at the Baikonur Cosmodrome.[3] Following two days of free flight, it docked with the forward port of Mir's core module at 00:54:17 GMT on 23 August.[4] [5]
During the thirty eight days for which Progress M-9 was docked, Mir was in an orbit of approximately 379kmby396kmkm (235milesby246mileskm), inclined at 51.6 degrees. Progress M-9 undocked from Mir at 01:53:00 GMT on 30 September, and was deorbited few hours later at 07:45, to a destructive reentry over the Pacific Ocean.[6] [4] The Raduga capsule landed in the Kazakh Soviet Socialist Republic at 08:16:24 GMT.[5]
