Spacecraft
editProgress 6 was a Progress 7K-TG spacecraft. The sixth of forty three to be launched, it had the serial number 106.[4][5] The Progress 7K-TG spacecraft was the first generation Progress, derived from the Soyuz 7K-T and intended for uncrewed logistics missions to space stations in support of the Salyut programme. On some missions the spacecraft were 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 were 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
editProgress 6 launched on 13 May 1979 from the Baikonur Cosmodrome in the Kazakh SSR. It used a Soyuz-U rocket.[2][7]
Docking
editProgress 6 docked with the aft port of Salyut 6 on 15 May 1979 at 06:19:22 UTC, and was undocked on 8 June 1979 at 07:59:41 UTC.[3][8]
Decay
editIt remained in orbit until 9 June 1979, when it was deorbited. The deorbit burn occurred at 18:52:46 and the mission ended at 19:35 UTC.[3][8]
