Progress 3 (Russian: Прогресс 3) was an unmanned Progress cargo spacecraft launched by the Soviet Union in 1978 to resupply the Salyut 6 space station. It used the Progress 7K-TG configuration, and was the third Progress mission to Salyut 6. It carried supplies for the EO-2 crew aboard Salyut 6, as well as equipment for conducting scientific research, and fuel for adjusting the station's orbit and performing manoeuvres.
Spacecraft
Progress 3 was a Progress 7K-TG spacecraft. The third of forty three to be launched, it had the
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.[3][4]
Launch and docking
Progress 3 was launched at 22:31:22 UTC on 7 August 1978, atop a Soyuz-U 11A511U carrier rocket flying from Site 31/6 at the Baikonur Cosmodrome in the Kazakh Soviet Socialist Republic. The rocket that launched it had the serial number Ye15000-138.[5] Following launch, Progress 3 was given the COSPAR designation 1978-077A, whilst NORAD assigned it the Satellite Catalog Number 10999.[6]
Following launch, Progress 3 began two days of free flight. It subsequently docked with the aft port of the Salyut 6 space station at 23:59:30 UTC on 9 August 1978.[3][7] At the time of its docking, Soyuz 29 was docked to the forward port of the station.
Mission
Progress 3 was the third of twelve Progress spacecraft used to supply the Salyut 6 space station between 1978 and 1981.
On 9 August 1978, whilst docked to Salyut 6, Progress 3 was catalogued in a
