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. 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.
