The Mars-Express spacecraft has released a photo showing the glacier at the bottom of the Korolev crater (80 km) in the northern hemisphere of the planet.
This has been reported by the European Information Agency on its website.

The photo taken by Mars Express is actually composed of several shots taken by a high-resolution HRSC camera 12 meters per pixel. Scientists have put together five distinct sequences over a width of 52 km to obtain the final photo.

The crater is well preserved and its bottom is covered with ice-cream. water that stays there all year. Its thickness in the center of the crater is 1.8 kilometers.
Glacier on Mars
The ice does not melt either in winter or in summer under the effect of the "cold trap". If on the Moon, the "cold traps" are called polar craters, whose bottom never falls under the rays of the Sun, then on Mars, the mechanism of their action is different: the air that falls in the area , limited by the crater stem, is cooled and immersed.
As a result, the glacier always has a thick "blanket" from cold air, which does not allow the walls of the crater to crumble.
Recall that on December 8, the US NASA space agency released a recording of wind noise on Mars. This noise was recorded by the seismograph and pressure sensors of the InSight probe, which landed successfully on the red planet at the end of November
