Overwhelmed with the latest images of Mars

The European Space Agency recently released satellite images taken by the ExoMars Trace Gas Orbiter spacecraft a few days ago about the sand dunes at the northernmost point of Mars.

Winter in the poles on the Red Planet causes carbon dioxide to freeze into a thin layer covering the sand dunes. In spring, this "ice" layer turns into steam, defrosting occurs from the bottom of the sand dune. As the ice melts, gas gushes out from the cracks, followed by sand. This creates a cream-like covering on the Martian surface.

NASA's Mars Reconnaissance Orbiter spacecraft also recorded the latest image from the Danielson Crater crater.

It is clear on the image that the rock and sand were frozen after being glued together. The amount of sediment in the crater changes over the years. Some areas still exist in many other areas wiped out. This causes the layer to resemble rice terraces.
