Two astronauts are once again safely aboard the International Space Station following an equipment malfunction during a spacewalk.
Chris Cassidy of NASA and Luca Parmitano of the European Space Agency were expected to stay outside of the space station for six-and-a-half-hours, but the mission was aborted after only 92 minutes.
NASA says the mission's flight director ended the spacewalk after Parmitano reported a buildup of water inside his helmet. Engineers are now working to find out what caused the leak.
