Roscosmos cosmonauts (from top) Sergey Prokopyev and Dmitri Petelin are pictured servicing components inside an Orlan spacesuit aboard the space station's Poisk module. They will exit Poisk's airlock at 9:20 p.m. EST on Wednesday and go on a spacewalk to transfer a radiator from the Rassvet module to the Nauka multipurpose laboratory module. #roscosmos #cosmonaut #walk #spacewalk #poisk #orlan #rassvet #nauka #international #space #station
