On July 16, astronaut Luca Parmitano started a “spacewalk”, an extravehicular activity (EVA) outside the International Space Station along with his colleague Chris Cassidy to carry out some maintenance and repair. The operation was to last about six and a half hours but after less than two hours it was interrupted because water was pouring into Parmitano’s spacesuit’s helmet. Now more details have been released about this problem.
