The orbiter of Roskosmos and the European Space Agency took several new images of Mars in the spring. Now scientists have decided to share these unique footage that show the interesting geological features of the surface of the Red Planet.

The bottom of the Antoniadi impact crater

The photo, taken on March 25, 2020, shows the bottom of the Antoniadi impact crater, 400 kilometers in diameter, which is located in the northern hemisphere of Mars. Although the image itself is blue, it does not overeat the actual color of the crater, but rather indicates certain rocks.

Lines that look like veins on oak leaves are called dendritic structures. They talk about ancient river networks in the area. Scientists suggest that the channels of the rivers were once filled with lava, but over time, the soft rocks that adjoined these lines were eroded, this process left behind such imprints.

Dunes in Green Crater

The image below, taken on April 27, 2020, shows a portion of an impact crater located inside a larger Green Crater in the Argyra Quadrangle in the southern hemisphere of Mars. The image also shows a black dune field on the right, surrounded by fiery rocks and partially covered with white ice. Ravines covered with ice are visible on the walls of the crater. Now scientists want to understand if there is any connection between these ice, cliffs and seasons. This image was taken just after the vernal equinox in the southern hemisphere of Mars, when the southernmost part of the crater (right) was almost completely free of ice, and the northern (center) was still partially covered with ice.

Argyre basin

The image of the Argyre Plain was taken on April 28, 2020, when Mars passed its vernal equinox. The winter ice is receding, but the ridge on the right is still covered in a haze of frost, as its ridge faces the pole and receives less solar heat. Such a beautiful effect is obtained due to the fact that on Mars the incoming solar radiation turns ice immediately into water vapor, "bypassing" the water stage.

Rocks of the Ius Chasma canyon

The bottom of the Ius Chasma canyon was filmed on May 5, 2020. This canyon is part of the Mariner Valley system, which is 4,500 kilometers long (a quarter of the planet's circumference). The Ius Chasma canyon is about 1000 kilometers long and 8 kilometers deep. This colossal size makes it twice the length and four times deeper than the Grand Canyon in Arizona, USA.

The unusual color of the bottom of the canyon is due to the composition of the rocks. Scientists believe that there could also be water here, which left behind a salt sediment.
