ESA probe captures breathtaking Martian giant ice lake

According to foreign media BGR reports, The ESA Mars Express (Mars Express) probe captured an image of a huge impact crater lake on the north pole of Mars. ESA used the data collected in this mission to create a virtual video of the region flying over. This Martian lake is about 50 miles in diameter and has a water depth of more than one mile.

The incredible image you saw above was taken by the Mars Express Orbiter of the European Space Agency. The spacecraft is equipped with a high-resolution camera, enabling it to send back some quite amazing images. The original image was taken many months ago, but now, using all the images and data of the area collected by the orbiter, the space agency has stitched together a video of a virtual”flying” crater, the effect is very amazing.

This well-preserved impact crater is located in the northern lowlands of the Red Planet, in the south of the large Olympia Undae dune that partially surrounds the Martian arctic cap. It is full of water ice all year round. The bottom of the crater is two kilometers below its edge, surrounded by a 1.8-meter-thick domed sediment, which is a huge non-polar ice reservoir on Mars.

Water ice is permanently stable in the Korolev crater, because the deepest part of this depression is a natural cold trap. The air above the ice layer will be cooled, so it is heavier than the surrounding air:Because the air is a poor conductor of heat, the water ice hills effectively shield the heating and sublimation.

Crater lakes are not uncommon on the planets and moons of the solar system. In fact, the same is true of the earth. There are more than one water body on the earth that can be directly attributed to large impacts from space objects. India’s huge Lake Lonar was the result of an asteroid impact between 35,000 and 50,000 years ago. It was filled with water and then recently turned pink, although scientists are still trying to figure out why .
