Watching a movie about Mar's and what happens to a human body in space without a suit.

Vacuum would cause the body to explode and then whatever was left would freeze. It would be messy.

Don't believe everything you see in a movie. An unprotected person exposed to the vacuum of space would survive for a few moments, and even a couple of minutes, though he would probably not be conscious. And he wouldn't explode, although his body would inflate. His blood wouldn't boil but the nitrogen in his blood would begin to bubble up (gas embolism). What would ultimately kill him would be the lack of oxygen, or the cold of space.

If an astronaut was unfortunate enough to find himself exposed to the vacuum of space without a suit, he would survive if rescued immediately. More details are provided in the articles below.

Lol not quite.

It depends on if you exhaled or not. If you attempt to hold your breath, the air inside your lungs would expand probably rupturing your lungs but that’s about it. You would be dead within about 10-20 seconds.

If you exhale prior to exposure, you could last maybe a minute or two before suffocation.

Water on your skin would vaporize and your body would swell slightly, but not explode. The saliva in your mouth would also boil.

Contrary to popular belief, you would actually probably feel hot without any atmosphere to radiate away body heat. Once dead, your body would mummify or freeze depending on how close to a star you are. It wouldn’t decompose due to lack of an atmosphere.

" It wouldn’t decompose due to lack of an atmosphere."

Not quite true. Freezing would limit decomposition, but heated areas would still have some decomposition from stomach acids and other chemicals in the body. In some specific conditions anaerobic bacteria and fungi could still work at decomposition for a while. Ultimately, solar wind and the effects of light itself would abrade skin and evaporate volatile parts, like water. Over time, a desiccated husk with micrometeorite pitting might remain. Until then the body would act more like a tiny weak comet than a lump of mass.

Would a person look like this in space without a helmet?
