Stunning pictures of Korolev, the full ice crater on Mars – 12/21/2018


It looks like a huge path of virgin snow that is located in the center of desertion. But the truth is that this is the snapshot held by the Mars Express y orbit European Space Agency (ESA) and crater Korolev, i Mars. And the banking layer seen in the picture is not snow, but water ice, present throughout the year.

Mosaic compiled by the image Five stripe of different images taken with each other in a different orbit by the Mars Express High Resolution stereo camera (HRSC).

Korolev, which is 82 km wide and is located close to the northeast of Mars, large field of dunes, known as Olympia Undae, is a good example of Crater Martian have to keep it well.

The ice layer of water is in the middle of the crater 1.8 km or thick. This frozen deposit forms a glacier that contains 2,200 km3 or rew not polar on Mars. That is always present because of a phenomenon, known as "cool trap": between the ground and the edge of the crater there is a distance of 2 km.

The deepest part of the crater includes ice, which cools the air above this ice deposit. The cold air is heavier than the hot one that falls, so it creates some kind of layer of cold air, multiple on the ice, as if it were & # 39; protective darian. That cold layer is what guarantees that the ice does not heat or disappear.

The mission Mars Express He was launched on June 2, 2003 and reached the Red Plaid six months later. He came to an orbit around Mars on December 25, so this month they will be met 15 years since the start of the program from the science of this ship.

The Martian crater is its name, Korolev, from a Russian scientist considers the father of space technology, the Russian Sergei Korolev.

Among others, Korolev launched several well-known trips, such as the Sputnik program, which gave the first artificial satellites to orbit around the Earth. He also took part in the Vostok and Vokshod programs exploring space space; Vostok was the first spacecraft that Yuri Gagarin took to a space in 1961. He also worked on the predecessors of the Soyuz successful spacecraft.
