Progress ISS Resupply

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

Progress MS-07 was docked with the aft docking port of the Pirs module. This Progress flight was intended to mark the debut of the new two-orbit rendezvous profile which was not possible when the original launch date had to be scrubbed.[3]

Cargo

The Progress MS-07 spacecraft delivered around 2549 kg of supplies and provisions to the International Space Station. The payload included 700 kg of propellant to refuel the station’s Zvezda service module, 23 kg of oxygen and 24 kg of air to replenish the station's atmosphere, 420 kg of water, and 1382 kg of dry cargo, food, spare parts and other equipment for the station's six-person crew.[4]

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.[3]
