The cause of the disappearance of water on Mars

Названа причина исчезновения воды на МарсеScientists came to the conclusion that this process and stripped Mars of a once abundant water supplies.

Mars became a dry desert because of the unique atmospheric phenomena, found researchers from the American geophysical Union.

Previous studies have shown that in the upper atmosphere of the red planet there is water vapor.

But, according to the laws of physics, he wasn’t supposed to be there, as it couldn’t overcome the cold air layers at medium altitude.
New scientific work has helped to establish the cause of the anomaly, according to Geophysical Research Letters.

Every two years, when the southern hemisphere of Mars comes summer, cold layers of the atmosphere are extremely hot, and at a height of 60-90 kilometers formed “window”. Through it, water vapor and comes from the bottom layers to the top.

In addition, play a role, and dust storms. They block sunlight, but not getting to the surface, the rays strongly heat the atmosphere. This has created favorable conditions for the circulation of tiny particles of water ice are formed around the dust particles and transferred with them to greater heights.

When water gets into the upper layers of the molecules is transferred to the poles. The rest are exposed to ultraviolet solar radiation and broken down into hydrogen and oxygen, then the first disappears into space.

Apparently, its atmosphere is more permeable than the earth, and can not keep the water from evaporating into space.

Earlier it was reported that experts have found traces of living organisms in a meteorite that came to Earth from Mars.
