Progress ISS resupply | |
Progress MS-25 (Russian: Прогресс МC-25), Russian production No.455, identified by NASA as Progress 86P, was a Progress spaceflight launched by Roscosmos to resupply the International Space Station (ISS). It was the 178th flight of a Progress spacecraft.
History
[edit]The Progress-MS is an uncrewed freighter based on the Progress-M featuring improved avionics. This improved variant first launched on 21 December 2015. It has the following improvements:[1][2][3]
- 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 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
[edit]A Soyuz-2.1a launched Progress MS-25 to the International Space Station from Baikonur Site 31 on 1 December 2023. Around 2 days after the launch, Progress MS-25 automatically docked with Poisk and continued its mission.
End of mission
[edit]Progress MS-25 undocked from Poisk on 28 May 2024 at 08:39 UTC and was deorbited for a destructive reentry on 29 May 2024 at 11:48 UTC.
Cargo
[edit]The MS-25 cargo capacity is 2,528 kilograms (5,573 lb) as follows:
- Dry cargo: 1,500 kg (3,300 lb)
- Fuel: 515 kg (1,135 lb)
- Oxygen: 40 kg (88 lb)
- Water: 420 kg (930 lb)
