The probe MRO managed to get a new razor-sharp images of the landslides in an unnamed crater in the Arctic circle of Mars. NASA experts said that the cause of this disaster was the melting of dry ice (frozen carbon and water) on the slopes of this crater.
Signs of landslides are numerous ravines that can be seen on the edges of the crater. They appear during the Martian winters, when the surface of the red planet formed layers of dry ice. During the subsequent melting of the softened soil is not kept on the slope and rushes to the bottom of the crater, along with melt water, forming large gullies that are visible from space. Thus in the Northern hemisphere winters are milder and shorter, causing landslides do not occur as frequently. Therefore, the resulting photos have great scientific value.
