MADRID (DPA) .- New images of high resolution HiRISE image device on top of NASA's orbiter MRO

Mars

, Reveal the ability of erosion of the wind on the surface of the Red Planet.

The picture above shows many sand dunes. They have
An elongated shape of a half-moon called "the dunes of the archan." They are formed by the continuous action of the wind blowing in the same direction.

The orientation of these dunes indicates that the wind blows from right to left (east to west). The wind
He keeps shifting grains of sand along the longest slope of the dune toward the top. The small movements on the slope are caused by this movement. When the grains of sand reach the top, they fall on a steep and shorter slope, which, as a result, has no objections. It is a gradual movement of sand that causes the sands to move slowly over time.

Another image taken by the HiRISE camera shows how surface erosion reveals several shades of bright layers, probably precipitation deposits, on the Martian surface.

Recent geological features are, in this case, sand dunes and trouble that revolve in the top of all the rocks.

HiRISE operates at visible wavelengths, just like human eyes, but with a telescopic lens that produces resolution images that have never been seen in planet search missions. These high-resolution images allow scientists to distinguish between one-meter objects on Mars and to study morphology in a much more complete way than in the past.
