On Dec. 24, 2013, NASA astronaut Mike Hopkins, Expedition 38 Flight Engineer, participates in the second of two U.S. spacewalks, spread over a four-day period, which were designed to allow the crew to change out a faulty water pump on the exterior of the Earth-orbiting International Space Station. He was joined on both spacewalks by NASA astronaut Rick Mastracchio, whose image shows up in Hopkins' helmet visor.
NASA astronaut Chris Cassidy, Expedition 36 flight engineer, uses a digital still camera during a session of extravehicular activity (EVA) as work continues on the International Space Station. A little more than one hour into the spacewalk on July 16, 2013, European Space Agency astronaut Luca Parmitano (out of frame) reported water floating behind his head inside his helmet. The water was not an immediate health hazard for Parmitano, but Mission Control decided to end the spacewalk early.
Inside the Cupola, NASA astronaut Chris Cassidy, an Expedition 36 flight engineer, uses a 400mm lens on a digital still camera to photograph a target of opportunity on Earth some 250 miles below him and the International Space Station. Cassidy has been aboard the orbital outpost since late March and will continue his stay into September.
