ISS spacewalk was cancelled due to the presence of water in an astronaut’s helmet.
Tim Kopra and Tim Peake had to cut short their spacewalk. The reason was the formation of a water bubble in Tim Kopra’s helmet. The staff of the ISS was assisted as they removed their helmets and spacesuits.

Furthermore, an inquiry will be made into what prompted the water bubble to form in the first place. The crew members are safe and sound and out of danger. The astronauts also fixed some technical stuff that needed their attention.
Due to the technical glitch, the spacewalk lasted only 4 hours and 43 minutes instead of the six and a half hours’ duration it should have been. Tim Kopra noticed the slight change of atmosphere when the water bubble started expanding inside his helmet.
By the time he felt the full repercussions of the event, the crew that were engaged in the spacewalk had been recalled to the ISS. Kopra had witnessed a close call. Had he remained in this condition any longer he may have drowned in his own helmet.
In 2013 a similar event took place and another astronaut was involved. He faced a tougher situation than Kopra. But he too was saved from any danger in the nick of time.
Kopra was wearing the selfsame spacesuit that the aforementioned astronaut had been wearing. It had been repaired and had even functioned well, but it seems to have malfunctioned a second time.
When Kopra entered the ISS, his helmet was wet inside and the fluid was from the cooling system of the spacesuit. It was not from his sweat or any other source.
NASA didn’t want to take any chances so it aborted the spacewalk after only four hours and 43 minutes. By the time Tim Kopra made it back to safety he almost couldn’t breathe. It was an instance of how things could go wrong anytime in space.
