History
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:[3][4][5]
- 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
After a two-day delay, the Progress MS-07 lifted off on 14 October 2017, at 08:46:53 UTC. The spacecraft docked at the station on 16 October 2017, at 11:04:07 UTC. Progress MS-07 was launched from the Baikonur Cosmodrome in Kazakhstan, atop a Soyuz-2.1a rocket.[1]
Docking
Cargo
Spacewalk
Once the Progress arrived at the station, Expedition 53 commander Randolph Bresnik and flight engineer Joseph M. Acaba prepared for a spacewalk, on 20 October 2017, to accomplish a variety of maintenance tasks outside the complex. This included the replacement of a fuse on the station's Canadian-built Dextre robot, replacing an external camera and light fixture, and removing thermal insulation from two spare units to prepare them for future relocation.[4]
Undocking and decay
Progress MS-07 undocked from the Pirs on 28 March 2018, at 13:50:30 UTC. The vehicle continued with experiments until 26 April 2018.[6]
