Luca Parmitano Spacewalk in This Week at NASA

European Space Agency astronaut Luca Parmitano, Expedition 36 flight engineer, attired in an Extravehicular Mobility Unit (EMU) spacesuit, 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, Parmitano 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.
