Progress MS-15 (Russian: Прогресс МC-15), Russian production No. 444, identified by NASA as Progress 76P, is a Progress spacecraft launched by Roscosmos to resupply the International Space Station (ISS). This is the 167th flight of a Progress spacecraft.
A Soyuz-2.1a launch vehicle was used to launch Progress MS-15 to the International Space Station.
Progress MS-15 was launched at 14:26:21 UTC from Baikonur Cosmodrome Site 31 on a fast-track trajectory. Following a nominal launch, Progress MS-15 docked with the Pirs port on the ISS two orbits later at 17:45:00 UTC.
Around 3 hours 20 minutes after the launch, Progress MS-15 successfully docked automatically at the nadir port of the Pirs module at 17:45:00 UTC, where it is expected to remain until April 2021. After its mission is complete, it will depart and re-enter the Earth's atmosphere for destruction over the South Pacific Ocean.
The Progress MS-15 spacecraft delivered 2,540 kg (5,600 lb) of cargo, with 1,430 kg (3,150 lb) of this being dry cargo. The following is a breakdown of cargo bound for the ISS:
The Progress MS-15 is scheduled to remain docked at the station through April 2021, when it will depart with trash and the Pirs module (to make room for the Russian Nauka module, which was delayed from 2007) and re-enter the Earth's atmosphere for destruction over the South Pacific Ocean.
