Wiseman and Gerst will work outside the International Space Station for about 6-1/2 hours Tuesday, Oct. 7. They set their spacesuits to internal battery power at 8:30 a.m. EDT Tuesday morning, signifying the official*start of the spacewalk. The spacewalkers will move a failed cooling pump from temporary to long-term storage on the station's truss. They also will install a new relay system that will provide backup power options to the mobile transporter, which moves the large robotic arm around the outside of the space station.> Wiseman and Gerst Conduct First Spacewalk of Expedition 41Image Credit: NASA/ESA/Alexander Gerst
