On October 07, 2014 American astronaut Gregory Wiseman and German astronaut Alexander Gerst performed the spacewalk to move a failed ammonia pump module to an external stowage platform. The hatch of the Quest module was opened at 12:30 UTC. They also replaced a broken television camera light, used during spacecraft arrivals and departures, and installed a backup payload power system on the mobile transporter used to move the station's robot arm and attached equipment from one worksite to another. The EVA lasted 6 hours and 13 minutes.
