The discovery of water in the helmet of a US astronaut brought an early end to a spacewalk today at the International Space Station, NASA said.
"The crew is in not in any danger whatsoever," said NASA commentator Rob Navias after astronaut Tim Kopra reported feeling a glob of water about four hours into the spacewalk. However, the situation brought back memories of a harrowing incident in 2013 when Italian astronaut luca Parmitano's helmet began rapidly filling with water and risked drowning him.
