Progress ISS Resupply |
Progress MS-12 (Russian: Прогресс МC-12), identified by NASA as Progress 73P, was a Progress spacecraft used by Roscosmos to resupply the International Space Station (ISS).[3] This is the 164th flight of a Progress spacecraft.
History
Progress was the first cargo spacecraft to fly in space (1978), and also the first to bring freight back to Earth, thanks to a Raduga capsule. It was developed to supply the Salyut 6 space station and which was subsequently supply the crews of Salyut 7, Mir and from the International Space Station. It enabled space station crews to stay in space by bringing consumables (food, water, fuel, oxygen) and spare parts.[4]
The Progress-MS is a uncrewed freighter based on the Progress-M featuring improved avionics. This improved variant first launched on 21 December 2015. It has the following improvements:[5][6][7]
- New external compartment that enables it to deploy satellites. Each compartment can hold up to four launch containers. First time installed on Progress MS-03.
- Enhanced redundancy thanks to the addition of a backup system of electrical motors for the docking and sealing mechanism.
- Improved Micrometeoroid (MMOD) protection with additional panels in the cargo compartment.
- Luch Russian relay satellites link capabilities enable telemetry and control even when not in direct view of ground radio stations.
- GNSS autonomous navigation enables real time determination of the status vector and orbital parameters dispensing with the need of ground station orbit determination.
- Real time relative navigation thanks to direct radio data exchange capabilities with the space station.
- New digital radio that enables enhanced TV camera view for the docking operations.
- The Ukrainian Chezara Kvant-V on board radio system and antenna/feeder system has been replaced with a Unified Command Telemetry System (UCTS).
- Replacement of the Kurs A with Kurs NA digital system.
Pre-launch
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]
Launch
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]
Docking
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).
Cargo
The Progress MS-12 spacecraft delivered 1,164 kilograms (2,566 lb) of dry cargo (in the cargo compartment).[3]
- 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
- 880 kilograms (1,940 lb) of propellant in the integrated propulsion system to the International Space Station.
The dry cargo consisted of:[3]
- 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
- 192 kilograms (423 lb) of NASA cargo.
Undocking and decay
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]
