The new results obtained from the interplanetary station NASA Mars Reconnaissance Orbiter” (MRO) refute the theory of scientists that the gullies on Mars were created as a result of activity of liquid water.
In this regard, professionals need to explore and find out the history of the relief formation on the red planet. The term “gullies” on Mars, scientists involve some deepening of the soil in the upper part, channels, and aprons of deposited material at the bottom.
The contrast of the veins is that the ravines are not prone to seasonal darkening and fading, and can change the soil due to external exposure due to liquid. Scientists had to make more than a hundred analyses of data obtained from the spectrometer MRO and about a hundred “gutters” on the red planet. As a result, they have not found the presence of water, so the basic theory of the appearance of the gullies were taken the theory of the freezing and thawing of carbon dioxide. On the surface of Mars there is a large number of gullies that have become the hallmark of the planet. Most of them are located at latitudes between 30-50 degrees in the Northern and southern hemisphere. The slope is directed to the poles of the red planet. The reason for the extension of the theory of the origin of gullies is that on the Ground of their occurrence is associated with exposure liquid.
Scientists have noted that not detected the presence of hydrated minerals characteristic of our planet and Mars, so you should exclude the theory about the origin of the ravines in the activity of the water.
