The earth is not the only planet, which is characterized by the change of seasons. New photos taken by NASA show the arrival of winter on Mars.
The appearance of Mars changes depending on the time of year. First and foremost, the landscape form the polar caps, whose thickness can vary from 1 m to 3.7 km. Growing or decreasing, they create seasonal phenomena in the atmosphere and on the surface of Mars.
The temperature on the planet ranges from -153 °C at the poles in winter to +20 °C at the equator in summer. For middle latitudes, the figures are from -50 °C to 0 °C. During the winter lowering the temperature of carbon dioxide, which mostly includes the atmosphere of Mars, is transformed into dry ice.
Dry ice is deposited on the surface of the planet, “drawing” the various patterns, depending on the terrain. Automatic station Mars Reconnaissance Orbiter has sent to Earth a series of images showing Mars in the cold season.
And with the arrival of spring, reminiscent of NASA experts, the dry ice begins to crack, to melt and vaporize, so that the surface of the red planet will again change its appearance.
