The European Space Agency has published pictures that were taken with the probe "Mars Express" showing alternating climate change on the Red Planet. Scientists have discovered at the bottom of a Martian crater sediment, which scientists believe originated as a result of alternating wet and dry faz.Pomimo of the crater Danielson also seen a sharp ridge. It is quite possible that the sedimentary layers were formed here, first with water and then later due to wind erosion occurred. Water could come from groundwater sources. Scientists have already found numerous signs that the surface of Mars previously had large bodies of water, and even contained the remains of the ancient lake systems. Just recently, the probe "Mars Express" vyvil Acidalia Planitia region remains of former water resources. Now and in the crater of Danielson have pictures of sedimentary layers. Under assumptions of researchers, the orientation of the ridge indicates a strong north-easterly and northerly winds, from which subsequently destroyed the original dry deposition. Interesting, but in a nearby crater Kalocsa, which is named after the Hungarian town, can not see the sedimentary layers. Rather, access to underground water sources alleged was not there, or perhaps it was formed when Mars was no longer liquid water.
