Note - even in a fantastic movies cosmonauts, as a rule, never go into space without space suits. I wonder what happened with the man, if he were in almost airless space environment without any protective equipment? According to experts, we should live in such an extreme situation would have remained no more than 90 seconds...

During the first 10-15 seconds, we felt like the whole surface of the body evaporates moisture, and would feel ice cold. So "icy abyss" is not the way it actually exists! Then we will likely twisted would nausea, as the gases from the stomach and intestines, began to crowd in. If ears at this point clogged grey, then the problems will be added...

Heart started to beat faster, but then your heart rate has gradually fallen, along with blood pressure. But venous pressure started to grow as education in the body of gas bubbles.

If we have not guessed to put on thick elastic suit, the body can swell to twice due to a shift of fluid in the soft tissues in the gaseous state, and the skin is tightened. However, our "outer shell" strong enough to not be ripped to pieces.

As our body will evaporate moisture, we will feel more and more cold. And if we find ourselves in direct sunlight, you probably have and earn strongest sunburn. Such is the paradox!

Next - due to the lack of oxygen our skin will become bluish-purple hue: experts call this effect cyanosis. If you try to hold your breath, then, according to "the Collection of data on space biology"will "improving internal-lung pressure"that "will is so strong expansion of the chest that may cause breaks in the lungs and broken capillaries. Held-the air is squeezed out from the lungs into the chest and through the damaged blood vessels gets directly to the General bloodstream.

And through the bloodstream, air bubbles already spread throughout the body and can easily reach vital organs such as the heart and brain". Something similar can be experienced when on Board of an aircraft flying at high altitude. But in space, it is several times stronger.

When will expire in about 90 seconds since your first spacewalk, the blood pressure will drop to 47 Torr, which will lead to to boiling blood and heart failure (compared to the normal atmospheric pressure of 760 Torr). After this come death.

However, if the time to restore the level pressure, "sacrifice space" can still be brought into compliance. However, for some time it will lose the vision and ability to move, and in a few days will not taste food.

Curious, and under what circumstances we can get into this deplorable situation? First of all, when you crash of the space Shuttle. Well, imagine the ship broke up into fragments, and you have thrown out into space... Though it is unlikely that you and the ship will be without a suit. But spacesuits sometimes susceptible to containment. By the way, at the time it depressurization caused the accident descent module "Soyuz-11"dropped June 30, 1971. Then killed the entire crew - Soviet cosmonaut Georgy Dobrovolsky, Vladimir Volkov and Viktor Patsaev...

Hereafter you can find yourself overboard on someone's malicious intent. Well, like you on the Earth in the metro pushed onto the tracks or thrown out of the window... it Happens! God forbid, of course, because the method of killing just savage!

Finally, another option is for fans of extreme sports. To stay 90 seconds in a vacuum, to experience all "charms" - and back, in a safe environment... Although it is unlikely to do this is to wait a minute and a half, will be enough for half a minute to impressions remained for the rest of your life...

But even if you are completely sure that you keep the situation under control, it is better not to risk and not to go beyond the spacecraft without elastic armor and other protective equipment. Everything can turn into a tragedy. Alas, space is still too aggressive environment for mankind...
