Second spacewalk ends early

NASA reports: Expedition 36 Flight Engineers Chris Cassidy of NASA and ESA's Luca Parmitano ended their spacewalk at 13:29 GMT, 15:39 CEST, only 1 hour, 32 minutes into the planned 6 1/2 hour venture outside the International Space Station.
Flight Director David Korth decided to terminate the spacewalk early after Parmitano reported a buildup of water inside his helmet. After returning the airlock, Parmitano performed an expedited process to remove his suit. Both astronauts are safely back in the space station, and engineers are continuing to evaluate data to determine the cause of the leak.
