The Mobile Servicing System, which includes the transporter and Canadarm2, plays a key role in station maintenance tasks.<\/p>\n\n\n\n<p>A second U.S. spacewalk is set for Oct. 15. Wilmore will don a U.S. spacesuit and follow Wiseman outside the Quest airlock for a 6-1\/2 hour excursion. Gerst will serve as the spacewalk choreographer. The goal of the excursion is to replace a failed voltage regulator component on the starboard truss of the station called a Sequential Shunt Unit that stopped operating in May, taking down one of eight power channels on the station\u2019s electrical system. They will also move external camera equipment in advance of a major reconfiguration of station modules next year for the arrival of new docking adapters for commercial crew vehicles.<\/p>\n\n\n\n<p>The first Russian spacewalk of Expedition 41 is scheduled for Oct. 22. Cosmonauts Alexander Samokutyaev and Max Suraev will wear Russian Orlan spacesuits and exit the Pirs docking compartment at 9:24 a.m. They will remove and jettison an experiment and a pair of antennas as part of their spacewalking schedule.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Astronauts Reid Wiseman of NASA and Alexander Gerst of the European Space Agency completed the first of three Expedition 41 spacewalks at 2:43 p.m. EDT Tuesday.
