Probe captures seasonal changes on Mars

NASA astronomers by machine Mars Reconnaissance Orbiter were able to observe
Seasonal changes in the North Pole of Mars. These changes are caused by the formation of ice on the Martian surface of CO2 and its subsequent melting under the sun.

Since the melting of ice in the spring begins at the bottom of the ice layer, where the transparent ice in contact with the dark Martian soil, high pressure gas from time to time thrown up, thus creating intricate patterns on the surface of the Red Planet. Gas drags sand that is carried by the wind, resulting in the formation of ice, dark stripes. In summer the ice melts completely, and thus, the surface becomes dark again.
