U.S. spacewalk on ISS on This Week @NASA - October 10, 2014

Aboard the International Space Station, Expedition 41 Flight Engineers Reid Wiseman of NASA and Alexander Gerst of the European Space Agency donned U.S. spacesuits for an October 7 spacewalk to relocate a failed cooling pump and to install a backup power cable device for the stations rail car system. The failed pump was replaced with a spare and is being temporarily stowed near the Quest airlock and the back-up power cables are for the unlikely event that the Mobile Transporter rail car on the stations truss loses power.
