When the frozen carbon dioxide melts all in the summer, a unique mark is revealed in the harmony environment. They are known as “Araneidoform terrain” because they look like spiders in space. Some of these spider terrain are more than 1km and some have hundreds of legs. They are often found in the swarm. The image above was taken by the Mars Reconnaissance Train in 2009.
The process of creating this spider formation to reinstate the temperature and pressure of Mars was not fully understood, but it recurs.
When spring arrives at Mars, a strong wind occurs, and the characteristic spiral pattern of the Mars Arctic hat is believed to have been created over the years by the wind from the center to the surrounding area. The spiral pattern is due to the Core Oli effect, when the rotation of the planet bends the wind process.
The dark part of the spiral is actually a deep canyon, which has been cut for a long time in the spring breeze. The Chasma Borreale, which is seen to the right side of the pole cap in the image, is especially spectacular. Grand Canyon (about 450 kilometers) and up to 2 km depth.
The strong spring breeze also also moves the sand on the surface of Mars, as in the desert of the earth.
The white objects found in the image are frosts around the high -end sand dunes and are static while they are frozen. When the temperature rises in the spring and this ice melts, the sandy tidal starts to move again due to the action of the wind.
“As we saw, the beginning of spring in Mars is very active. Diniega can also be said to be ‘explosive’. “I think it’s noisy to break and explode.”
