what would happen if you took off your spacesuit on mars?

Question

Obviously, there is not enough oxygen on mars to breathe, and UV levels are pretty high. But if you took off a hypothetical spacesuit for say, 5 mins, would there be any effects on your body, and would the air feel the same as on earth?

Answer 1

It would be like a scuba diver getting the 'bends'. Your blood would literally boil (not from heat, but from low pressure) as the gasses nitrogen, oxygen, and CO2 came out of solution into gas bubbles.

There wouldn't be time for any UV to do any damage, as you'd likely die from an air-embolism in your brain within minutes.

The Scwarzenegger movie was "Total Recall". At the end of the movie, it shows him, the woman-hero, and the bad guy out on the surface without space suits, and I think it is a pretty accurate portrayal of what would happen.

Answer 2

The atmospheric pressure is near to zero, since the atmosphere of Mars is 100 times thinner than that of Earth. It consists of 95% carbon dioxide (CO2), 3% nitrogen, and 1.6% argon (there is no oxygen). Since no one could hold their breath for 5 minutes (your number) you would pass out and then die as you lay on the surface trying to get oxygen into your system. You would probably also freeze. Mars' surface temperature AVERAGES -81 °F (-63 °C). The temperature ranges from a high of 68° F(20° C) to a low of -220° F(-140° C). Mars is much colder than the Earth.

Answer 3

Same effects as fish experience, which live 20,000 feet below the surface of the ocean and then taken up by a scientist. Their system shuts down in less then 2 minutes, because of the low pressure on the surface. However, there are some sorts of whales, who can live for some time in both worlds. Maybe humans could get conditioned to survive for 5 minutes.

Answer 4

The air pressure on Mars is 100 times lower than on the Surface of the Earth. It is about the same as Earth's air pressure at an altitude of 100,000 feet. The source has data up to 50,000 feet. At that altitude you pass out in 10 seconds. It would be worse on Mars. I don't know how long it would be before you would die though.

Answer 5

The atmospheric pressure on Mars is so low that it is almost a vacuum. It is certainly far too low to sustain a human, even if it was pure oxygen. Any air in your lungs would rush out immediately, tiny blood vessels in your skin and in your lungs would rupture, your lungs would fill with fluid because of the low pressure, and you would be dead well before the five minutes were up.

Answer 6

The gravity is slightly less then that of earth. So that wouldn't cause any strange effect. You may be suddenly burned or frozen quickly, but the freezing is about -300 to 0 C so it wouldn't be that quick either.. I imagine though of course, since its not just oxygyn you breathe, but rather oxygyn that runs to your brain, you would simply pass out and fall over, dying in about 10 seconds though (similar to when a gas leak or nitrogen leak happens here on earth and you run out of oxygin to your brain.) Remember, unlike earth where when your underwater your brain still gets oxygyn, it isn't just breathing it that matters.. it has to reach your brain.

Now, the pressure. Its low.. but not low enough for the sort of things you saw earlier such as "you'd explode". Honestly, its only a 100th of earths, so you may feel your insides trying to stretch out very gently maybe, if you werent already passed out due to lack of oxygyn.

Answer 7

Yes. The pressure on Mars is so low that it is nearly a vacuum (for all intents and purposes), so not only would you get fried by the UV but you would undergo all the unpleasant effects of depressurization as well (fizz, pop!)

Answer 8

Hi. The pressure is very low so breathing would not be possible even if oxygen was present. Five minutes may be enough to kill you.

Answer 9

shall we see somebody merely attempt to take their area greater healthful off on mars, they wont get their intestines sucked out, they're going to particularly suffocate and die (loss of oxygen) Nope, no person lives on mars (different than the martins of direction :P) No, the water is already on mars, its merely frozen on the ice caps simply by fact its too a techniques remote from the solar My concept is that we take a brilliant number of rocket ships actually crammed with poop and merely sell off all of it on mars then toss some plant seeds is and spot what it does.

Answer 10

atmospheric and surface pressure is different than on earth, which means your body might implode. there was a shwarzeneger flick (true lies, i think) that demonstrated this pretty graphically.
