Gerst during EVA 27

ISS041-E-066940 (7 Oct. 2014) --- European Space Agency astronaut Alexander Gerst, Expedition 41 flight engineer, uses a digital still camera to expose a photo of his helmet visor during a session of extravehicular activity (EVA) as work continues on the International Space Station. Also visible in the reflections in the visor are various components of the space station and a bright sun. During the six-hour, 13-minute spacewalk, Gerst and NASA astronaut Reid Wiseman (out of frame), flight engineer, worked outside the space station's Quest airlock relocating a failed cooling pump to external stowage and installing gear that provides back up power to external robotics equipment.
