When frozen carbon dioxide melted in the summer, special signs were revealed on Mars. They are called the terrain of ARANIDOROR, because they look like spiders when viewed from space. Some terrain like this spider is longer than one km and some have hundreds of legs. They are often found in the herd. The image was taken by the Mars reconnaissance trajectory when watching the male hemisphere in 2009.
The process of creating spider formats is not fully understood, although JPL is working to mimic the temperature and pressure of Mars to create them.
The appearance of spring on Mars also brings strong winds, and it is believed that the spiral model typical of the northernmost limit of Mars has been created for many years by the winds blowing from the middle. Cap's mind to peripheral. The spiral model is due to the Coriolis effect, which is when the rotation of a planet bends the wind process.
The darker parts of spiral are actually deep canyons that have been cut for a long time by the spring monsoon. Chasma Boreaee, can be seen on the right of the center of the pole lid in the image, especially spectacular. It is as long as Grand Canyon (about 450 km) and up to 2 km deep.
The strong spring monsoon also moves sand dunes on the surface of Mars, like the winds of the desert on Earth.
The white things you see in the image are frosts surrounding high sand dunes, still static while freezing. When the temperature rises in the spring and this tape melted, the sand alcohol will start moving again due to the effect of the wind.
As we have seen, the beginning of spring on Mars is very positive. You can even say 'booming', Diniega said. I imagine it will be very noisy, with cracks and booming.
