History
Summarize
Perspective
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:[2][3][4]
- 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
Progress MS-08 launched on 13 February 2018 from the Baikonur Cosmodrome in Kazakhstan atop a Soyuz-2.1a rocket, at 08:13:33 UTC.[1]
Docking
Progress MS-08 docked on 15 February 2018 with the aft docking port of the Zvezda module, at 10:38 UTC.[1][5]
Cargo
The Progress MS-08 spacecraft delivered 2,494 kg of cargo and supplies to the International Space Station. The following is a breakdown of cargo bound for the ISS:[3][5]
- Dry cargo: 1,390 kg
- Fuel: 890 kg
- Oxygen and Air: 46 kg
- Water: 430 kg
Progress MS-08 also includes two nanosatellites: Tanyusha YuZGU-3 (1998-067PJ) and Tanyusha YuZGU-4 (1998-067PK) (a.k.a. Radioskaf RS-8 and Radioskaf RS-9) with a mass of 2.5 kg, which was developed jointly by RKK Energia and students at the South-Western State University, YuZGU, in the city of Kursk. The satellites will be launched by spacewalking cosmonauts.
Undocking and decay
Undocking on 23 August 2018, at 02:16 UTC. And decay in the atmosphere and its debris entered the Pacific Ocean, on 30 August 2018.
