Russian and European astronauts to conduct rare joint spacewalk

Two astronauts — one European and one Russian — will put on puffy white spacesuits and exit the airlock on the International Space Station for a spacewalk on Thursday, marking the first time in more than 20 years such a joint endeavor has taken place.

Samantha Cristoforetti, an Italian astronaut with the European Space Agency, and Russian cosmonaut Oleg Artemyev are scheduled to exit the ISS at 10 a.m. ET and spend about seven hours working to install a 36-foot-long new robotic arm on one of the space station’s modules.

Spacewalks are a routine endeavor on the ISS, but they typically involve two Americans or Europeans, an American and a European, or two Russians working together. The last time a European astronaut and a Russian cosmonaut left the ISS together wearing Russian-made Orlan spacesuits was in April of 1999, according to NASA. (An American and a Russian also did a joint spacewalk in 2009.)

Thursday’s spacewalk will be Cristoforetti’s first and Artemyev’s sixth. Their joint venture comes as tensions on Earth between Russia and the United States and its allies have hit a fever pitch amid the Ukrainian war, though NASA has repeatedly said the conflict has not affected cooperation in space.

Also on Thursday, Artemyev and Cristoforetti will deploy “ten nanosatellites designed to collect radio electronics data,” and they’ll install “a telescopic boom” — a sort of crane-like structure — that will assist with future spacewalks.

The spacewalk will be the sixth carried out at the ISS so far in 2022 and the 251st overall. Astronauts routinely leave the station to maintain its exterior, install new hardware or conduct science experiments.

ESA will livestream the spacewalk on ESA Web TV on Thursday. Viewers can spot Cristoforetti by the blue stripes on her spacesuit, while Artemyev will wear red stripes.
