TURN UP THE SOUND AND HEAR THE WHITE NOISE

In 2013, Luca Parmitano experienced one of the most dangerous EVA emergencies ever. During a spacewalk, water began leaking into his helmet from the suit's cooling system. The water eventually covered his eyes, ears, and nose, making it difficult to see or hear. He had to navigate back to the airlock partially blind. Had the leak continued longer, drowning inside the helmet was a real possibility.

The explosion disabled the Apollo CSM electrical and life support systems, necessitating the cancellation of the planned third lunar landing. The crew used the lunar module as a life boat until the command module could restart for the re-entry into Earth's atmosphere.
