Roscosmos cosmonauts Prokopyev and Petelin completed a 5-hour spacewalk to deploy a radiator on the ISS’s Nauka module, marking the sixth spacewalk in 2023 and the 263rd for ISS maintenance.
Roscosmos cosmonauts Sergey Prokopyev and Dmitri Petelin concluded their spacewalk on May 12 at 5:01 p.m. EDT (2:01 p.m. PDT) after 5 hours and 14 minutes. They began their spacewalk to deploy a radiator on the International Space Station’s Nauka science module at 11:47 a.m. EDT.
Prokopyev and Petelin completed their major objectives, which included deploying a radiator on the International Space Station’s Nauka science module, connecting electrical, mechanical, and hydraulic lines, and filling a pair of cooling loops with coolant.
