This magnificent crater bears witness to the existence of water ice on Mars

on mars,AtmosphereAtmosphere Thinness and absence of water do not allow corrosion processes to be very effective. Just windswinds It is slowly eroding, grain by grain, the barren terrain of the Red Planet. It is not enough to erase the effects of multiple impacts that puncture its surface. This is much better. Because these magnificent craters, with clear lines as if they had just been created, allow researchers to better understand nature geologygeology From March.

Another evidence that water remained present on the Red Planet, especially in the form of ice in the Earth's interior, even after its lakes and oceans evaporated.
