I can't think of anything else that'd immediately injure you...

Let's say you're at the outersphere of Earth, just outside the atmosphere in open space. I know the sun is super blinding and you need air...

So if you have an oxygen tank + NASA-approved shades = you're all set right?

Just thinking it'd be cool to be in an open space naked.

It would be so much more cost effective if NASA would just provide oxygen tanks and shades instead of those super complex space suits that cost tons of money.

No. You cant.

Dude, do you realize how cold it is in space? Not to mention that it's a complete vacuum.

You'd die almost instantly.

But, no, you can't.

absence of heat would get to you. Also space suits might offer some protection from radiation.

Exactly, the vacuum of space would cause your body to pretty much explode. (Air has weight and pressure, our bodies require this pressure to stay together) Put a marshmellow in a vacuum and you will get the idea.

There's nothing in space for you to lose heat to except through radiation, which would be slow wouldn't it?

And if your O2 tank is airtight you'd be fine as your body is liquid for the most part, and you've closed off the biggest opening.

I'd vote for you'd be fine for a while. Far longer than a few seconds.

Vacuum's and temperatures are your major issues. Google how cold it is on the moon when the sunlight isn't hitting where you are standing vs how hot it is there when it is hitting it.

haha, you would freeze to death so quickly. Atmosphere holds in the heat for planets and there is no atmosphere in space. I guess if you got just the right amount of meters from the sun you might be nice and warm and could be naked. I would be concerned about any orifices getting hurt by the vacuum i.e. your eyes bleeding, your penis being sucked out backwards from the hole.

Lots of misinformation in this thread...

You would not explode. Your eyes and ears would be the most susceptible to damage and would need to be shut/covered. Space isn't "cold" like people are saying. It is nothing. In order for your body to feel cold, you need to be losing heat. Most of our heat loss is done through exposure to air which has less kinetic energy than our skin cells, thus transferring heat out of our body. In space, there are no particles at all, so this type of heat loss is essentially non-existant. You have to radiate it which is much less efficient for a human, meaning you would not die instantly from an extremely "cold" enviornment since that isn't what it is.

Simply because we are acclimated and built for the pressure on earth doesn't mean we would explode or compress into nothing in a different atmosphere. Space shuttles are pressurized and don't explode because of the metal container, but this is exactly how our skin would function. The weak spots would be eyes and ears, but this could be mitigated if all air in the lungs was exhaled immediately. You should be able to live for 20-25 seconds with nothing other than your skin and a will to survive.

At NASA's Manned Spacecraft Center (now renamed Johnson Space Center) we had a test subject accidentally exposed to a near vacuum (less than 1 psi) in an incident involving a leaking space suit in a vacuum chamber back in '65. He remained concious for about 14 seconds, which is about the time it takes for O2 deprived blood to go from the lungs to the brain. The suit probably did not reach a hard vacuum, and we began repressurizing the chamber within 15 seconds. The subject regained conciousness at around 15,000 feet equivalent altitude. The subject later reported that he could feel and hear the air leaking out, and his last conscious memory was of the water on his tongue beginning to boil."

:confused:

Is body temperature enough to boil water in a near complete vacuum? :Q Interesting.

Wrong. Direct exposure to sunlight would fry you from any distance even close to earth's orbit. Think how hot your skin can feel on a really hot day, and then multiply by the inverse of how much is absorbed, reflected, and scattered by the atmosphere.

You would either die of radiation or burns, not from lack of oxygen, pressure, or temperature.

I think this was in a movie, but I can't remember which one. Maybe Event Horizon or something where a guy had to jump from one airlock in a space station to another. He exhaled all his air, covered his eyes, and went for it. His veins started to pop out and he almost went CGI but got to the other airlock in time.

I did some further research on this and he is right. Temperature is still a major problem though because while you will not freeze to death, you will become uncomfortably hot and eventually die since the body produces heat faster than it radiates heat in an environment where no particles exist to lose heat. If you are exposed to the sun then you can just forget about surviving at all since that will increase how hot you get. Aside from temperature, you can also die there for other reasons aside from suffocating too.
