Progress MS-05 (Russian:Прогресс МC-05), identified byNASA asProgress 66P, was aProgress spaceflight operated byRoscosmos to resupply theInternational Space Station (ISS).
TheProgress MS is a uncrewed freighter based on the Progress-M featuring improved avionics. This improved variant first launched on 21 December 2015. It had the following improvements:[2][3][4]
The launch of the Progress MS-05 mission was originally planned for 16 October 2016, and by the end of 2016, it was postponed to 21 February 2017, in the wake of theProgress MS-04 accident. The extra time was used to return the third stages of already assembled vehicles to the manufacturing plant for additional inspections ofRD-0110 engines, which were suspected in the loss of Progress MS-04. The engine on the third stage of theSoyuz-U vehicle assigned for the Progress MS-05 mission was replaced.[1]
The Soyuz-U rocket for the Progress MS-05 mission and all subsequent launchers carrying Soyuz and Progress spacecraft were retrofitted with onboard cameras capable of transmitting live images during the ascent to orbit. The cameras were installed on the exterior of the intertank compartment of the third stage. The resulting video could help to understand the rocket's behavior during the flight.[1]
The launch of Progress MS-05 was to be ensured for 139.8 million rubles.[1]
The Progress MS-06 spacecraft delivered 2,640 kg of cargo and supplies to the International Space Station, including anOrlan-MKS spacesuit. This was a replacement for the suit lost onProgress MS-04. The following is a breakdown of cargo bound for the ISS:[3][1]
Progress MS-05 was launched on 22 February 2017 at 05:58:33 UTC[5][6] from theBaikonur Cosmodrome inKazakhstan. It used the 786th and lastSoyuz-U rocket.[7]
Progress MS-05 docked with thePirs module at 08:34 UTC on 24 February 2017. During the automated docking process, Russian cosmonautsSergey Ryzhikov andOleg Novitsky were on stand by at the manual control system,TORU, console inside thePirs service module to take over docking operations if needed. Progress MS-05 will remain docked at the station for almost four months before departing in June 2017 for its deorbit intoEarth's atmosphere.
After six months at theInternational Space Station, the Progress MS-05 cargo ship undocked from the Pirs, on 20 July 2017, at 17:46 UTC. The three-minute braking manoeuvre with the main engine of the cargo ship was scheduled to begin at 20:58 UTC, followed by reentry into thedense atmosphere at 21:32 UTC on 20 July 2017. Surviving debris of the spacecraft were calculated to impact the remote area of thePacific Ocean at 21:41 UTC on 21 July 2017.[1]
