Astronauts Reid Wiseman of NASA and Alexander Gerst of ESA carried out an Extra Vehicular Activity (EVA) spacewalk commencing at 1230 GMT from the Quest airlock on 7 October 2014. The EVA finished 6 hours 13 minutes later at 1843 GMT. During the spacewalk the astronauts relocated a failed Pump Module (PM) that was in a temporary stowage location following its removal from the ISS last December. While the PM has technically failed due to a faulty internal valve, if an external valve is later connected, the unit could be brought back into use as a viable spare.
During their stint outside of the station, the spacewalking astronauts also completed a number of other routine maintenance and “get-ahead” tasks such as replacing a failed light and rerouting ethernet cables.
