When frozen carbon dioxide melted in the summer, distinctive signs are detected on the Mars scene. These are known as “Araneidoform Terrain”, as they look like spiders when they are seen from space. Some of these spider -like ground shapes are more than one kilometer, some of which contain hundreds of legs. It is often found in swarms. The above photo was taken by Mars Etiion of the survey when watching the southern hemisphere in 2009.
The processes that create these chicks are not completely understood, although the JPL simulates temperatures and Mars pressure to re -create them.
Spring’s arrival on Mars also brings strong winds, and it is believed that the distinctive spiral pattern of the northern polar mobs of Mars has been created over many years by the winds that blow from the center of the cover to its surroundings. The spiral style is due to the effect of Coriolis, which is when the planet rotates the wind path.
Dark parts of a whirlpool are in reality deep grooves, which have been cut over a long period of wind in the spring. Chasma Boreale, which appears to the right of the center of the polar cover in the image, is particularly amazing. It is as long as the Grand Canyon (about 450 km) and a depth of 2 km.
The strong spring winds also transport the sand dunes on the surface of Mars, just like the winds in the deserts on the ground.
The white things that you see in the picture are the frost surrounding the high sand dunes, which remain fixed while freezing them. When the temperatures rise in the spring and this ice melts, the sand dunes will start moving again due to the wind work.
“As we have seen, the beginning of the spring on Mars is very active. Deniga says:” You can even say “explosive.” “I imagine that it will be very noisy, with the cracks and explosion.”
