Russia’s Progress 77 cargo ship docks with the International Space Station – Space.com

A Russian space vessel carrying an algae experiment, long-duration medical examinations and thousands of pounds of other cargo and supplies docked safely at the International Space Station Wednesday (Feb. 17) after a cosmonaut took manual control of the craft during its approach.

The uncrewed cargo ship Russian Progress MS-16 cargo ship (also known as Progress 77) met up with the orbiting complex at 1:27 a.m. EST (0627 GMT), when it latched onto the station's Pirs docking component, according to an update from NASA. It launched from the Baikonur Cosmodrome in Kazakhstan on Sunday (Feb. 14).

While designed to dock itself at the space station, the Progress spacecraft was controlled manually during the docking by Russian cosmonaut Sergey Ryzhikov, the station's commander, due to an issue with the cargo ship's Kurs automated rendezvous system, NASA officials said.

"Control switched over to the TORU system for manual flying of the ISS Progress 77 resupply ship due to signal strength from Kurs automated system," NASA wrote in an update on Twitter. "Station commander Sergey Ryzhikov is in control of the Progress 77 from a control panel inside Zvezda."

NASA was unable to carry a live video of the docking on NASA Television which it typically tries to do because of ongoing power outages in Texas affecting agency personnel and associated broadcast capabilities, NASA said in an update prior to the event. A severe winter storm Sunday (Feb. 14) knocked out electricity to millions of Texans, with 3.6 million homes and businesses still in the dark in subfreezing temperatures as of Tuesday (Feb. 16), CNN said.

Progress 77 brought 5,424 lbs. (2,460 kg) of supplies and cargo to the Expedition 64 crew. The delivery included new research experiments, crew supplies (such as clothing and food), fresh water, nitrogen gas and propellant for the station's Zvezda service module propulsion system.

The spacecraft will also play a historic role when leaving the space station later this year. NASA said that when it is time, Progress will not undock as previous missions have; instead, it will remain connected to Pirs and pull the entire docking compartment away from the ISS for a planned destruction in Earth's atmosphere. Pirs has been in service for almost 20 years and a replacement is coming soon, NASA said.

"Pirs' departure from the space station is scheduled to take place just days after the launch of the 'Nauka' multipurpose laboratory module on a Proton rocket from Baikonur," NASA said in a statement. "The multifunctional docking port and research facility will dock automatically to the port vacated by Pirs."

A few experiments were bundled into the Progress delivery, including the following ones listed on the Energia website (Energia is the prime developer and contractor of the Russian crewed spaceflight program):
