Progress ISS Resupply
 

Progress MS-15 (Russian: Прогресс МC-15), Russian production No. 444, identified by NASA as Progress 76P, was a Progress spacecraft launched by Roscosmos to resupply the International Space Station (ISS). This was the 167th flight of a Progress spacecraft.[5]

History

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.

Launch

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.[3][8]

Docking

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,[3][8][9] where it remained until February 2021.[4] After its mission was completed, Progress MS-15 departed and re-entered the Earth's atmosphere for destruction over the South Pacific Ocean.[4]

Cargo

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:[1]

  • Dry cargo: 1,430 kg (3,150 lb)
  • Fuel: 620 kg (1,370 lb)
  • Oxygen: 46 kg (101 lb)
  • Water: 420 kg (930 lb)

Undocking and decay

The Progress MS-15 remained docked at the station through on 9 February 2021, when it departed with trash and re-entered the Earth's atmosphere for destruction over the South Pacific Ocean.[4] The Pirs module, originally scheduled to be removed and discarded at the end of this mission,[10][11] will stay attached to the station until the arrival of the Nauka module.
