Progress MS-20 (Russian: Прогресс МC-20), Russian production No.450, identified by NASA as Progress 81P, is a Progress spacecraft launched by Roscosmos to resupply the International Space Station (ISS). This will be the 173rd flight of a Progress spacecraft.

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:[3][4][5][6]

  • 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.
  • Unified Command Telemetry System (UCTS) replaces previous Ukrainian Chezara Kvant-V as the Progress spacecraft's on-board radio and antenna/feeder system.
  • Replacement of the Kurs A with Kurs NA digital system.

Launch[]

On 3 February 2021, the State Commission for Testing of the Piloted Space Systems, chaired by Roskosmos head Dmitry Rogozin, approved the latest ISS schedule for 2021 and the first quarter of 2022.

A Soyuz-2.1a will launch Progress MS-20 to the International Space Station from Baikonur Site 31 on 3 June 2022[1][2] on a fast-track trajectory.[7][8] Around 3 hours 20 minutes after the launch, Progress MS-20 will automatically dock to the zenith (space-facing) port of the MIM2 Poisk module and continue its mission for 196 days, supporting Expedition 67 and Expedition 68 missions aboard the ISS.

Cargo[]

The Progress MS-20 spacecraft is loaded with 0 kg (0 lb) of cargo, with 0 kg (0 lb) of this being dry cargo.

  • Dry cargo: 0 kg (0 lb)
  • Fuel: 0 kg (0 lb)
  • Oxygen: 0 kg (0 lb)
  • Water: 0 kg (0 lb)

Undocking and decay[]

The Progress MS-20 is scheduled to remain docked at the station through late 2022, when it will depart with trash and re-enter the Earth's atmosphere for destruction over the South Pacific Ocean.
