Mars — the planet most resembles Earth in a number of familiar characteristics. For example, the local change of the seasons is similar to earth,their duration and exceeds our about 2 times. Image, the Orbiter Mars Express, show the bright patches of ice and deep dark depression at the North pole of Mars. Their detection indicates the presence in the region of strong winds and storms when establishing on the red planet winter. The layers of ice covering the area at this time begin to experience severe changes in its composition and extent, and was able to capture Mars Express during its new mission.
How to look like the polar caps of Mars?
The extreme climate of Mars, responsible for the presence on the fourth planet from the Sun thick layers of water ice, are responsible for the appearance of the polar caps of the planet of the layer of frozen carbon dioxide falling out of the thin Martian atmosphere on top of the usual ice, according to the portal sciencealert.com. The extremely low density of the atmosphere coupled with the relative distance from the Sun provide in the winter, the average temperature of -143°C (-225°F), which is several times below the modern Antarctic indicators. With the help of powerful full-color camera HRSC, the scientists were able to examine the processes occurring at the North pole of Mars, capturing a unique phenomenon characteristic only of this planet of the Solar system.
Red and brown Martian depressions are part of a larger spiral pattern of depressions, which diverge from the center of the North pole. From above they look like a pattern of stripes of a Zebra. Scientists believe that the creation of this unusual pattern responsible of the so-called katabatic winds that carry dense air at lowerOn the red planet, they carry cold dense air from the polar glaciers and the frozen plateau down to the lowerrepresenting valleys and depressions. Due to the constant rotation of the planet, the ice of the North pole of Mars are affected by the Coriolis effect, which creates a spiral pattern emanating from the center of the North pole.
