Progress 8(‹See Tfd›Russian:Прогресс 8), was aSovietuncrewedProgresscargo spacecraft which was launched in 1980 to resupply theSalyut 6space station.
Spacecraft
[edit]Progress 8 was a Progress 7K-TG spacecraft. The eighth of forty three to be launched, it had theserial number108.[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 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
[edit]Progress 8 launched on 27 March 1980 from theBaikonur Cosmodromein theKazakh Soviet Socialist Republic.It used aSoyuz-Urocket.[7]
