Cosmonaut Sergey Prokopyev rode the European robotic arm (ERA) as he and Dmitri Petelin installed debris shields and relocated a portable workstation on the station during a spacewalk today. Today's spacewalk was the tenth out of the International Space Station this year. Prokopyev and Petelin began their spacewalk at 10:44 a.m. EDT today and completed their excursion six hours and 35 minutes later at 5:19 p.m. Cosmonaut Andrey Fedyaev assisted the duo from inside the Nauka science module commanding the ERA. #roscosmos #cosmonaut #spacewalk #walk #nauka #rassvet #poisk #esa #european #robotic #arm #international #space #station
