Last year during a spacewalk outside the ISS, an astronaut was about to die as water was leaking into his helmet. He was so lucky that he survived, thanks to another astronaut. However, here's the exclusive video of that incident.
NASA astronauts have fixed the critical cooling line leakage at ISS. But while repairing the critical cooling line leakage at ISS, an astronaut experienced an issue with his spacesuit and hence, NASA has delayed its next repairing.
NASA has sent two astronauts at ISS to fix the critical cooling line leakage for which NASA had to shut down all non-essential equipment inside the ISS. Today, the astronauts have completed the first stage of repairing cooling line leakage at ISS for 6.5-hour spacewalking.
