In this image from video made available by NASA, Italian astronaut Luca Parmitano, right, describes the water in his helmet on the Tuesday, July 16, 2013 spacewalk with U.S. astronaut Chris Cassidy, right, during a news conference with U.S. astronaut Karen Nyberg on the International Space Station on Thursday, July 13, 2013. Parmitano, Italy's first and only spacewalker, could not hear or speak by the time he re-entered the space station on Tuesday, 1½ hours after stepping out. He also said he had difficulty seeing because of the big globs of water in his helmet and elsewhere in his suit. (AP Photo/NASA) less
