ISS036-E-019675 (16 July 2013) — NASA astronaut Chris Cassidy, Expedition 36 flight engineer, participates in a session of extravehicular activity (EVA) as work continues on the International Space Station. A little more than one hour into the spacewalk, 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.
