Russian Progress cargo ship docks at space station after two-day journey

An uncrewed Russian cargo spacecraft has arrived at the International Space Station after a two-day journey to deliver food, fuel and supplies for the orbiting outpost’s crew.

The Progress MS-17 freighter linked up with the Poisk mini research module on the space-facing side of the station’s Russian segment on Thursday (July 1). The automated docking occurred at 8:59 p.m. EDT (0059 GMT on July 2).

Launched on Tuesday (June 29) from the Baikonur Cosmodrome in Kazakhstan, Progress MS-17 completed 34 orbits of Earth on its way to the space station. During its rendezvous, the ship was predicted to come within the vicinity of two pieces of SpaceX hardware.

“Information shows that a Starlink satellite system spacecraft and a Falcon 9 rocket fragment [are] expected to approach the Progress MS-17 spacecraft on July 1,” Roscosmos, Russia’s state space corporation, stated in a June 30 release

Flight controllers monitored the situation, but no maneuvers were needed to avoid an impact, with the Starlink satellite expected to fly by at a distance of about 1 mile (1.6 kilometers) and the rocket fragment passing at about 1,600 feet (500 meters). The two encounters occurred about three minutes apart.

Packed aboard Progress MS-17 is more than 3,600 lbs. (1,630 kilograms) of supplies for the space station’s Expedition 65 crew, including commander Akihiko Hoshide of the Japan Aerospace Exploration Agency (JAXA) and flight engineers Mark Vande Hei, Shane Kimbrough and Megan McArthur of NASA, Thomas Pesquet of the European Space Agency (ESA) and Oleg Novitsky and Pyotr Dubrov of Roscosmos. 

Among the cargo to be unpacked are Russian science experiments designed to develop countermeasures for osseous (bone) lesions and to study the impact of long-duration space missions on cosmonauts’ activities. There is also research into pharmaceuticals to modulate the human immune system and hardware to map the global structure of space weather and meteorological processes from orbit.

Progress MS-17 will spend almost five months docked to Poisk at the station. The cargo craft is then scheduled to perform an automated undocking and relocation to the new “Nauka” multipurpose laboratory module in late October. Named for the Russian word for “science,” Nauka is slated to be launched to the space station this summer.

After changing ports and being repacked with refuse from the space station, Progress MS-17 will undock in November to re-enter Earth’s atmosphere for its safe destruction. 

Progress MS-17 is the 78th Russian cargo craft to launch to the International Space Station since August 2000.
