The snapshot captured by the orbiter Mars Express of the European Space Agency (ESA) Korolev Crater on Mars, it goes around the world and does not stop surprising millions of people.
It looks like a huge virgin snow trail located in the middle of a desert. But not: it's about the Korolev crater. The banking layer seen in the image is not snow, but water ice, present throughout the year.
The image is a mosaic composed of five stripes of different images each taken in a different orbit by Mars Express's high-resolution stereo camera.

The crater has 82 kilometers wide and is located on the plains north of Mars, very close to a large dune field, known as Olympia Undae.
The deeper parts of Korolev, those that contain ice, act as a natural trap for the cold: the air moving on the ice container cools and sinks, creating a layer of cold air that is directly on the ice.
The crater is 82 kilometers wide and is located on the plains north of Mars.
By behaving like a shield, this layer helps the ice to stay stable and prevents it from getting hot and disappearing. The air is a bad conductor of heat, exacerbates this effect and keeps the Korolev crater permanently frozen.
The Mars Express mission was launched on June 2, 2003 and reached the red planet six months later.

The Martian crater gets its name Korolev, of a Russian scientist considered the father of space technology, the Russian Sergei Korolev.
Among others, Korolev has launched a large number of known missions, such as the Sputnik, which placed the first artificial satellites in orbit around Earth. (Infobae)
