What REALLY happens to us if we're exposed to the vacuum of space?
After many years of science fiction - either fantastical or trying to attain some level of realism - showing us that we explode, freeze, hemmorage or violently suffocate in space, can someone PLEASE definitively tell me what happens to living creatures (Russian dog or NASA monkey experiments, astronaut/cosmonaut accidents) when exposed to the vacuum of space?
I remember reading a story by an astronaut who came close to exposure (his suit leaked, if I recall correctly) and claimed it was like his skin was on fire and he nearly passed out... but that's not what I'm looking for. What happens from beginning to end? Also, has any film ever 'got it right'?
Thanks!
You do not explode, and you do not freeze instantly.
If you try to hold your breath, your lungs will tear, which is probably fatal even if you're brought back inside immediately.
If you exhale, your lungs collapse and begin actively removing oxygen from your bloodstream (and venting it to space). So, any blood flowing through your lungs becomes depleted of oxygen. It takes about 15 seconds for blood to travel from your lungs to your brain, so after about 15 seconds, you will fall unconscious. Around 3-4 minutes later, you will die of oxygen deprivation to your brain.
There is nothing to conduct heat to in space, so you don't freeze instantly the way you would if you were submerged in liquid helium. Instead, moisture from your skin and especially from any exposed mucus membranes (eyes, nose, throat) rapidly evaporates, causing a cooling effect. After a couple minutes, frostbite might become an issue, but the oxygen deprivation kills you much quicker than the heat loss.
Finally, there's the pressure change, which is only 1 atmosphere to 0 atmospheres of pressure. Divers routinely experience changes in pressure (during ascent) of 10 atmospheres or more, and for them, nitrogen narcosis (aka "the bends") is an issue. For someone ejected into space, the effects of nitrogen narcosis are minimal, and far less damaging than the lack of oxygen. A bit of pain in the joints is the most you could expect from the gas bubbles.
So, after a few minutes, you die of hypoxia. Your corpse would continue to lose heat and moisture via evaporation until it froze. Then the water would sublimate (going directly from solid to gas) until you were so cold that even sublimation ceased. At this point, you would look like a mummy. As time passed, your flesh would become pitted with micro-meteor impacts. You might also be a hazard for spacecraft in orbit.
