How long would you survive in space without a suit

Many of us have dreamed of going into space.

How would you die in space without a suit

Perhaps you've imagined what it would be like to visit the International Space Station or even explore new worlds. But traveling in space brings a whole set of challenges and hostile environments, so it's vital to recreate the conditions on Earth that have allowed life to evolve and flourish.

Spacesuits allow astronauts to venture outside their spacecraft for short periods, by providing the air, water, pressure and physical protection needed for a human to survive.

But what would happen without one of these advanced suits?

Sci-fi movies and shows, including "2001: A Space Odyssey" and "The Expanse," have portrayed astronauts suffering — and surviving — short exposures to outer space without a spacesuit, while others have depicted a range of grisly deaths. 

But here in the real world, how long could a person survive if thrust into the harsh vacuum of outer space?

The short answer is, not very long.
