Under a layer of Martian dust are huge deposits of water ice. That is the conclusion drawn by researchers from the University of Arizona, studied the strange craters on the surface of the Red Planet in the plain area of ​​Arcadia. According to researchers, a layer of ice in the area reaches a thickness of 40 meters and an area equivalent to the area of ​​California and Texas combined. The presence of water ice show unusual craters. Unlike conventional bowl-shaped craters craters in the area have a stepped structure. "Steps" craters, scientists say, could have been formed due to the different composition of the subsurface material. During the formation of craters weaker material easily pushed the blast. Using data from HiRISE camera apparatus MRO, scientists have made a three-dimensional model of the terrain covered with unusual craters. The researchers then used the radar apparatus SHARAD MRO. Comparing the data, experts have come to the conclusion that under the Martian regolith is a layer of water ice. Although scientists previously knew about the ice caps near the poles of Mars, the discovery of a huge amount of ice in the middle latitudes of the Red Planet was a surprise to researchers.
