Pre-launchEdit

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.[4]

LaunchEdit

Progress MS-12 was launched in 31 July 2019, at 12:10:46 UTC from Baikonur Cosmodrome in Kazakhstan, using a Soyuz-2.1a rocket.[3]

DockingEdit

Progress MS-12 docked with the Pirs docking module. The docking took place 3 hours 18 minutes 31 seconds into the mission (a new record time).

CargoEdit

The Progress MS-12 spacecraft delivered 1,164 kilograms (2,566 lb) of dry cargo (in the cargo compartment), 420 kilograms (930 lb) of water (in the Rodnik-system tanks), 51 kilograms (112 lb) of oxygen (in pressurized bottles), 850 kilograms (1,870 lb) of propellant in the refueling section and 880 kilograms (1,940 lb) of propellant in the integrated propulsion system to the International Space Station. The dry cargo consisted of: 394 kilograms (869 lb) of hardware for onboard systems, 27 kilograms (60 lb) of medical supplies, 1 kilogram (2.2 lb) of personal protective gear, 190 kilograms (420 lb) of hygiene items, 7 kilograms (15 lb) of repairs and servicing equipment, 20 kilograms (44 lb) of means of crew support, 282 kilograms (622 lb) of food, 13 kilograms (29 lb) of payloads, 38 kilograms (84 lb) of structural components and other hardware and 192 kilograms (423 lb) of NASA cargo.[3]

Undocking and decayEdit

The Progress MS-12 craft undocked from ISS on 29 November 2019 at 10:25 UTC, initiated braking maneuver at 13:39 UTC, re-entered Earth's atmosphere at 14:11 UTC (end of mission), with any remaining debris impacting a remote part of Pacific Ocean at 14:19 UTC.[3]
