If you were ejected into space how long would you survive?

lack of oxygen would kill you

Spacesuits are tremendously well insulated, enough to withstand hours in space before you felt the cold.  More then likely your oxygen would run out, but it wouldn't be as slow and painful as you think.  As the oxygen was thinning, you would get light-headed and pass out.  Then you would die.  Not fun, but then you probably wouldn't want to be ejected into space anyway.

You would die as a result of using up your oxygen.  Contrary to popular belief, space is not "cold" as we typically understand it.  Heat is lost in space by radiation thus even if you were exposed directly to space, you would cool only slowly.  There is very little in space to transfer heat energy.  It's sort of like putting your hand in a freezer, then grabbing ice in that freezer.  The air and the ice have similar temperatures, but the ice feels a lot colder because the heat in your hand transfers to the ice much more efficiently than to the air.

Sure and many will die in the future when the oxy runs out. I hate to think about that.

The body reacts to this condition rapidly. A complete lack of oxygen, which results in permanent physical damage or death, is called Anoxia. If the human body is deprived of oxygen for more than a few minutes, the person's brain, heart, and other organs will suffer damage, leading to unconsciousness and death.

The oxygen would last for about 10 hours, then you will slowly die of CO2 poisoning, you suffocate. The cold of space is not the problem in a space suit, and the batteries for the heaters and the life support system should keep you warm over the full 10 hours, but because there is only little air inside the space suit, once you run out of oxygen, the death will come within minutes.

Lets not forget that in the future, there will probably be spacesuits that recycle oxygen from the CO2,thus meaning that unless there will be direct damage to the apace suit, the astronaut inside would probably live forever, but even that would be unlikely as for he would probably die of starvation and thirst.

Obviously, it's NO!!!  It's becuase of the ff. factors: Lack of Oxygen, UV rays from the sun, and solar winds.

I think we should sell some of our space technology to the Arabs.  After all, they did form the AUASS (Arab Union for Astronomy and Space Sciences) back in 1998.  They should be encouraged and assisted in expanding their role in space, and even becoming a leader in space development.

In October, 2009, they held the Ninth AUASS Conference on Astronomy and Space Sciences--it took place at Khartoum in Sudan.

Flash - Cryogens are a great idea, but wouldn't we ask NASA to drop different canisters of these liquid cryogens onto the moon on different trips?  And shouldn't we wait for these gases to mix and settle down before attempting to bring any form of life there?  I'd wait at least 2 years and then take a reading to see what the atmospheric pressure is, and what the ratio of each gas in the atmosphere was, and if the temperature is ambient enough to support life.  

I like the idea of:  "Eating boiled cabbage, cauliflower and beans can help build up Methane gas in an atmosphere."
