How Fast Would You Die In Space

Sure in space there are a lot of gruesome ways to die like being tidally disrupted spagettified or irradiated or crushed in the atmosphere of some planet but i think the odds of any of.

How fast would you die in space. About 15 seconds after leaving the safety of the airlock you lose consciousness. Once you enter the vacuum of space it will take about 15 seconds for your o2 deprived blood to get to your brain. The short answer is that the lack of oxygen would make you black out after about.

In short being basically anywhere in space without a spacesuit would be catastrophic. If you ever find yourself exposed to the near vacuum of space so long as you don t try to hold your breath which would result in your lungs rupturing and thus pretty well guaranteed that the incident would be fatal you ll likely remain conscious for about 10 15 seconds with perhaps half that being useful consciousness. Heck even being in space in a spacesuit will do you some harm there s nowhere besides earth where you could survive any longer than two minutes.

So to protect astronauts nasa has developed elaborate space suits. The movie mission to mars has a scene that realistically demonstrates what would happen if an astronaut s space suit were to rapidly lose pressure and be exposed to outer space. Other sources here here and here also offer detail about how death would become you in space.

You wouldn t lose consciousness straight away. Expiring in space is no picnic. There is some good news to take away from this morbid message.

After another minute you d be dead by asphyxiation. If you get too close to the sun you will die. After about one minute circulation would stop altogether.

It might take up to 15 seconds as your body uses up the remaining oxygen reserves from your bloodstream and if you don t hold your breath you. You re not a corpse yet though. When this happens you ll pass out.
