Progress MS-12 (Russian:Прогресс МC-12), Russian production No.442, identified byNASA asProgress 73P, was aProgress spaceflight operated byRoscosmos to resupply theInternational Space Station (ISS).[3] This was the 164th flight of a Progress spacecraft.
TheProgress-MS is an uncrewed freighter based on theProgress-M featuring improved avionics. This improved variant first launched on 21 December 2015. It has the following improvements:[4][5][6][7]
In 2014, the launch was planned for 1 July 2018, rescheduled for 5 June 2019 and rescheduled to 31 July 2019. The liftoff had been initially set for the two-day rendezvous profile with the station, but the launch time was later shifted to enable a two-orbit (three-hour) flight to the station.[8]
Progress MS-12 was launched on 31 July 2019, at 12:10:46 UTC fromBaikonur Cosmodrome inKazakhstan, using aSoyuz-2.1a rocket.[3][9]
Progress MS-12 docked with thePirs docking module. The docking took place 3 hours 18 minutes 31 seconds into the mission (a new record time).
The Progress MS-12 spacecraft delivered 1,164 kg (2,566 lb) of dry cargo (in the cargo compartment).[3]
The dry cargo consisted of:[3]
The Progress MS-12 craft undocked from ISS on 29 November 2019 at 10:25 UTC, initiated braking maneuver at 13:39 UTC, re-enteredEarth's atmosphere at 14:11 UTC (end of mission), with any remaining debris impacting a remote part ofPacific Ocean at 14:19 UTC.[3]
