“I’m alone. I frantically think of a plan. It’s vital that I get inside as quickly as possible,” he wrote.

Parmitano realized Cassidy — making his way back to the air lock by a different route — could come get him. “But how much time do I have? It’s impossible to know,” he said.

That’s when Parmitano remembered his safety cable. He used the cable recoil mechanism, and its 3 pounds of force, to “pull” him back to the hatch. On the way back, he pondered what he would do if water reached his mouth. The only idea he came up with, he said, was to open the safety valve on his helmet and let out some of the water.

“But making a ’hole’ in my spacesuit really would be a last resort,” he wrote.

Parmitano said it seemed like an eternity — not just a few minutes — until he peered through “the curtain of water before my eyes” and spotted the hatch. Cassidy was close behind. The astronauts inside quickly began repressurizing the air lock, to get to the spacewalkers.

“The water is now inside my ears and I’m completely cut off,” he said.

He tried to stay as still as possible to keep the water from moving inside his helmet. He knew that because of the repressurization, he could always open his helmet if the water overwhelmed him. “I’ll probably lose consciousness, but in any case, that would be better than drowning inside the helmet,” he wrote.
