Progress 15 was a Soviet uncrewed Progress cargo spacecraft, which was launched in September 1982 to resupply the Salyut 7 space station.

Spacecraft

Progress 15 was a Progress 7K-TG spacecraft. The 15th of forty three to be launched, it had the serial number 112.[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.

The Progress spacecraft had a dry mass of, which increased to around when fully fuelled. It measured in length, and in diameter. Each spacecraft could accommodate up to 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

Progress 15 launched on 18 September 1982 from the Baikonur Cosmodrome in the Kazakh SSR. It used a Soyuz-U rocket.[7]

Docking

Progress 15 docked with the aft port of Salyut 7 on 20 September 1982 at 06:12 UTC, and was undocked on 14 October 1982 at 13:46 UTC.[8]

Decay

It remained in orbit until 16 October 1982, when it was deorbited. The deorbit burn occurred at 17:08 UTC.
