Scientists have described what happened to water on Mars

Explained another mystery of the red planet.

An international group of scientists found that Mars loses water faster than expected by the researchers on the basis of theories and observations. About it reported in a press release on EurekAlert! (translation —

Planetary scientists analyzed data from the probe Trace Gas Orbiter in the framework of ExoMars. Scientists have found that the gradual disappearance of the water in the upper atmosphere of the red planet. Because of sunlight water molecules are split into atoms of hydrogen and oxygen, and the weak gravity of the planet cannot prevent their volatilization into space. Thus large amounts of moisture accumulates at the altitude of 80 kilometers.

Some parts of the atmosphere are saturated and contain 10-100 times more water vapor than is theoretically temperature. In these figures the ability of water to exit from the atmosphere is greatly enhanced at certain seasons.
