You Don’t Explode in Space. Here’s What Happens.

You don’t explode in space. You don’t freeze either. Your blood doesn’t boil.
Almost everything the movies show you is wrong.

On June 30th, 1971, a Soviet capsule landed perfectly. All three cosmonauts
inside were dead — without a mark on them. A single valve had opened 168
kilometers up, and none of them were wearing pressure suits. They remain the
only humans who have ever died in space.

So what does a vacuum actually do to a human body?

In 1966, NASA technician Jim LeBlanc found out. His suit hose came loose
inside a vacuum chamber, and his last memory before losing consciousness was
his own saliva boiling on his tongue.

This is the real physics of vacuum exposure: ebullism, the Armstrong limit,
the fourteen-second window, and the one instinct that kills the people who
survive everything else.
