Mars Ekpress carries images of a crater of the Korolys-filled ice Science


The stunning Crater Crater in the northern part of Mars is filled with ice all year round thanks to a trapped layer of cold Mars air that keeps water frozen.

A 50-mile crater contains 530 cubic miles of water ice, just like Lake Bear Lake in northern Canada, and in the center of the crater ice is more than a mile.

Images that return from the red planet show that the lips around the crater impact are high above the surrounding plain. When thin Mars air passes through the crater, it becomes trapped and cooled to form an insulating layer that prevents the melting of ice.

The latest image is a composition of five comic book images taken from the Mars Explosion of the European Space Agency, which turned around in the orbit around the planet at Christmas in 2003. On the same day, the orbiter released the Beagle 2 lander, a British probe built on the budget it had brought, but it did not fully open on the surface.

Mars Ekpress photographed the Crater Korolev with a high-resolution stereo camera, an instrument that can select characteristics of 10 meters or 2 meters wide when used in super-resolution mode.

Evidence of the movement of spacecraft, rover and landing gear reveals ancient watercourses and lake beds on Mars. Huge amounts of frozen water were found on the poles of the planet. In July, astronomers used Mars Radar Radar measurements to find what seemed to be a 12-millimeter part of the gray waters below the surface of the planet.

Krater Korolev was named after Sergei Koroleva, a Russian rocket engineer and vessel designer known as the father of Soviet space technology. Korolev worked on the Sputnik program, which in 1950 sent the first artificial satellites to the space, and later the Vostok program that led Iuri Gagarin to the history books as the first man to orbit the Earth.
