SCIENCE.DK: Unbelievable picture: Satellite finds huge ice crater on Mars

White christmas on Mars! While there is intense interest in whether there is liquid water on Mars, so there is no longer any doubt that Mars has plenty of ice.

It confirms a new photo from the planet, writes The European space agency (ESA) in a press release, according to the Science.dk, where you can see even a photo of the crater.

the Photo shows a giant crater filled to the brim with ice.

the Crater, which ESA has named after the soviet rumingeniør Sergei Korolev, measuring a diameter of 81.4 kilometers and has a depth of 2 kilometers.

the Ice fills about 60 kilometers in diameter and 1.8 km in depth, which corresponds to a volume of about 2200 cubic meters of ice, where a part of the also consists of dust.

When the air on Mars, which incidentally is very thin, moves over the ice, cools down and sinks, resulting in a layer of cold air just above the ice.

Since air is a poor conductor of heat, the cold layer of air as a kind of insulator, protecting the ice from the warmer air and thus prevents it from melting.

It is in the context of ESA's Mars Express mission, which this month has 15-year anniversary, to the image of the crater taken.
