How long would you last in space without your helmet

Before reading this article i’d like you to take a moment of thought, how long do you think you would last in space without your helmet?

Give yourself an estimate and let me know in the comment section how long you first thought you’d last before reading

Ok i’m sure you’ve noticed astronauts with their big helmets and bulky suits

making them look like overfed hamsters learning how to walk ( no offence astronauts, i adore you )

Those suits are still very important

Astronauts wont be able to do their jobs without them

The space suits protect them from radiation, fast moving space dust and the extremely low pressure in space

Plus it provides the oxygen sustaining them while they’re exploring space

so yeah really important and expensive

At the time of writing this article the cost of a flight-rated NASA space suit was 12,000,000 US dollars

I had to check twice cause thought i wasn’t seeing right

Those suits are no joke

But what if let’s say the helmet cracks and you’re exposed to the immense vacuum

How Long Would You Last?

Well if that ever happens for starters i’d advice you not try holding your breath, don’t even think about it

The vacuum of space would pull the air out of your body, and if you have air in your lungs they’ll immediately rupture. Poof!

The oxygen in your body will also expand.

You’ll balloon up to twice your normal size, but you won’t explode. Your skin is elastic enough to hold you together. 

Any exposed liquid on your body will begin to vaporize. 

So the surfaces of your tongue and eyes will boil. Without air in your lungs, blood will stop sending oxygen to your brain. 

You’ll pass out after about 15 seconds. 90 seconds after exposure, you’ll die from asphyxiation. 

It’s also very cold in space. You’ll eventually freeze solid. 

It may sound like down right torture and i may not be able to get it off my mind but it’s just science
