Progress 12(Russian:Прогресс 12) was aSovietunmannedProgresscargo spacecraft, which was launched in January 1981 to resupply theSalyut 6space station.
Spacecraft
[edit]Progress 12 was a Progress 7K-TG spacecraft. The twelfth of forty three to be launched, it had theserial number113.[4][5]The Progress 7K-TG spacecraft was the first generationProgress,derived from theSoyuz 7K-Tand intended for uncrewed logistics missions to space stations in support of theSalyut programme.On some missions the spacecraft was also used to adjust the orbit of the space station.[6]
The Progress spacecraft had a dry mass of 6,520 kilograms (14,370 lb), which increased to around 7,020 kilograms (15,480 lb) when fully fuelled. It measured 7.48 metres (24.5 ft) in length, and 2.72 metres (8 ft 11 in) in diameter. Each spacecraft could accommodate up to 2,500 kilograms (5,500 lb) of payload, consisting of dry cargo and propellant. The spacecraft was powered by chemical batteries, and could operate in free flight for up to three days, remaining docked to the station for up to thirty.[6]
Launch
[edit]Progress 12 launched on 24 January 1981 from theBaikonur Cosmodromein theKazakh SSR.It used aSoyuz-Urocket.[2][7]
Docking
[edit]Progress 12 docked with the aft port of Salyut 6 on 26 January 1981 at 15:56 UTC, and was undocked on 19 March 1981 at 18:14 UTC.[3][8]
Decay
[edit]It remained in orbit until 20 March 1981, when it was deorbited. The deorbit burn occurred at 16:59 UTC.[3][8]
