According to NASA, International Space Station Expedition 36 Flight Engineers Chris Cassidy, KF5KDR, of NASA and Luca Parmitano, KF5KDP, of the European Space Agency ended their July 16 spacewalk at 1329 GMT, just 1 hour, 32 minutes into a planned 6-1/2 hour venture outside the International Space Station. NASA Flight Director David Korth decided to terminate the spacewalk early after Parmitano reported a buildup of water inside his helmet, apparently caused by a leak. Parmitano was rendered unable to hear or speak. Cassidy helped him back inside after NASA quickly aborted the spacewalk. After returning the ISS airlock, Parmitano performed what was called “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 problem, NASA said.
