Looks like "Open Water" in space.

Hrmmmm.....

It would be an interesting way to die. If i had a list of "ways I'd like to die", floating in space with a view of our planet and solar system would certainly be towards the top.

I can't imagine suffocating as a pleasant way to go.

Yeah, but suffocating while having the most magnificent view of the earth?

I could think of much worse ways to die.

Actually, I imagine that would be pretty peaceful. Fairly early on, you'd just pass out.

I'm with you. If it started to suck I would just pop the seal on my helmet.

that would be the easier way to go.

Actually, your body begins to panic when it senses too high a level of co2. It isn't pleasant or peaceful.

No way dude. Have you seen what happens?

That is on Mars not in space. In space you freeze instantly.

That always cracked me up. Their eyeballs are bursting out of socket, but when they get air back, everything is all back to normal.

There better be aliens coming to the rescue in this.

You wouldn't freeze. Just suffocate in about 15 seconds.

This is what would happen to your body in a vacuum:

How long can a human live unprotected in space?

If you don't try to hold your breath, exposure to space for half a minute or so is unlikely to produce permanent injury. Holding your breath is likely to damage your lungs, something scuba divers have to watch out for when ascending, and you'll have eardrum trouble if your Eustachian tubes are badly plugged up, but theory predicts -- and animal experiments confirm -- that otherwise, exposure to vacuum causes no immediate injury. You do not explode. Your blood does not boil. You do not freeze. You do not instantly lose consciousness.

Various minor problems (sunburn, possibly "the bends", certainly some [mild, reversible, painless] swelling of skin and underlying tissue) start after ten seconds or so. At some point you lose consciousness from lack of oxygen. Injuries accumulate. After perhaps one or two minutes, you're dying. The limits are not really known.

You do not explode and your blood does not boil because of the containing effect of your skin and circulatory system. You do not instantly freeze because, although the space environment is typically very cold, heat does not transfer away from a body quickly. Loss of consciousness occurs only after the body has depleted the supply of oxygen in the blood. If your skin is exposed to direct sunlight without any protection from its intense ultraviolet radiation, you can get a very bad sunburn.

How Long Can a Human Live Unprotected in Space?

If you *don't* try to hold your breath, exposure to space for half a minute of so is unlikely to produce permanent injury. Holding your breath is likely to damage your lungs, something scuba divers have to watch out for when ascending, and you'll have eardrum trouble if your Eustachian tubes are badly plugged up, but theory predicts -- and animal experiments confirm -- that otherwise, exposure to vacuum causes no immediate injury. You do not explode. Your blood does not boil. You do not freeze. You do not instantly lose consciousness.

Various minor problems (sunburn, possibly "the bends", certainly some [mild, reversible, painless] swelling of skin and underlying tissue) start after 10 seconds or so. At some point you lose consciousness from lack of oxygen. Injuries accumulate. After perhaps one or two minutes you're dying. The limits are not really known.

You would probably pass out in around 15 seconds because your lungs are now exchanging oxygen out of the blood. The reason that a human does not burst is that our skin has some strength. For instance compressed oxygen in a steel tank may be at several hundreds times the pressure of the air outside and the strength of the steel keeps the cylinder from breaking. Although our skin is not steel, it still is strong enough to keep our bodies from bursting in space.

Also, the vapor pressure of water at 37 C is 47 mm Hg. As long as you keep your blood-pressure above that (which you will unless you go deep into shock) your blood will not boil. My guess is that the body seems to regulate blood pressure as a gauge, rather than absolute pressure (e.g. your blood vessels don't collapse when you dive 10 feet into a pool).

The saliva on your tongue might boil, however. :eek:

I'll keep the helmet on

There's another trailer out today with more spinning through space - unfortunately they're giving up the entire plot with all this footage - so far I've seen about 7 minutes of the movie and its great stuff but I'm not sure how you sustain tumbling through space for two hours...

That said, I can't wait!
