This is the giant frozen crater of Mars – ElSol.com.ar – Diario de Mendoza, Argentina



Last Thursday, the European Space Agency published a picture taken by the Mars Express mission, which shows a large crater covered with what appears to be snowy, but is actually a large ice sheet.

It looks like a huge trace of virgin snow placed in the middle of some deserts. But the truth is that it is the snapshot captured by the orbiter Mars Express from the European Space Agency (ESA) of the Korolev crater.

According to the discovery, it is 82 km wide and lies in the lowlands of northern Mars, very close to a large dune field, known as Olympia Undae, it is a good example of a well-preserved martyrdom.

The water battle in the middle of the crater is 1.8 km thick. This ice-cold reservoir forms a glacier of about 2,200 km3 of non-polar ice on Mars. It is always present due to a phenomenon called "cold trap": between the ground and the edge of the crater there is a distance of 2 km.

The Mars Express mission was launched on June 2, 2003 and reached the Red Planet six months later. It resumed orbit around Mars on December 25, so this month marks 15 years since the beginning of this ship's science program.

The master's main study, Bruce Banerdt, emphasizes the importance of this achievement, "as important as the landing of InSight on Mars": "The seismometer is the highest priority instrument in InSightand we need it to complete three quarters of our scientific goals. "

The data recorded by this instrument will allow you to deepen everything that happens beneath the surface of the planet as they analyze the seismic waves. This stream of data begins to reach the ground when the seismometer is level, after which Banerdt ensures that "he has a bottle of champagne ready".
