It looks like a big trail of virgin snow located in the middle of some deserts. But the truth is that it's the snapshot captured by Mars Express orbiter European Space Agency (ESA) of the crater Korolev, i Mars. And the banker looked at the picture is not snow, but water is, present all year round.
The picture is a mosaic composed of Five strips of different images taken each other in another path of the Mars Express High Resolution Stereo Camera (HRSC).
Korolev, which is 82 km wide and is located in the lowland north of Mars, very close a big dune field, known as Olympia Undae, is a good example of Martian Crater well kept.
This is how Korolev looks, icecreamed on the planet Mars. (ESA)
The icing of water in the center of the crater has 1.8 km thick. This icy deposit forms a glacier consisting of 2,200 km3 is not polar on mars It is always present due to a phenomenon known as "cold trap": Between the ground and the edge of the crater there is a distance of 2 km.
The deepest part of the crater contains ice, which cools the air above this ice deposition. The cold air is heavier than the heat that rises, so it creates a kind of cold, perennial air on the ice, as though it were a protective shield. The cold layer is what guarantees it The ice does not heat or disappears.
The mission Mars Express It was launched on June 2, 2003 and reached the Red Planet six months later. It re-circulated around Mars on December 25th, so this month they are met 15 years since the start of the program of the science of this ship.
The Martian crater gets its name, Korolev, from a Russian scientist considered father of space technology, the Russians Sergei Korolev.
Among other things, Korolev launched a number of well-known missions, such as the Sputnik program, which put the first artificial satellites in circuits around the Earth. He also participated in Vostok and Vokshod programs of manned space research; Vostok was the spacecraft who took the first person, Yuri Gagarin, to seat in 1961. He also worked on the precursors of the successful Soyuz spacecraft.
