More than 15,000 mounds rise to the sky from the lowlands of the Planet of Chrys on Mars, located near the natural line of distinction between the southern and northern hemispheres of the planet. Geological features have long been interested in scientists who have not yet been sure that it created mounds.

A new analysis of images and data collected by orbital devices shed light on their history. The data obtained show why there can be such an amazing difference between the northern and southern hemispheres of the planet - there was water on the Red Planet, writes CNN Science.

Education, covering the size of Texas, can be seen in the pictures taken by NASA and the orbital devices of the European Space Agency. Mounds act as time capsules that can help astronomers reveal the secrets of the past Mars.

" The oldest are at the bottom and consist of a breed, which is about four billion years old. For a geologist, to consider these layers the same as viewing the pages of the book - each of them tells the story, ”says the leading author of the study, Dr. Joe Maknele, a planetologist and doctoral program of the London Museum of Natural History.

The mounds are located near the upcoming landing of the Esa Exomars Rosalind Franklin, which is expected in 2028. It is likely that they will be investigated by the Markout, which will help to find out about the history of water on the Red Planet, and accurately determine the resources for future human research.

Scientists used images collected by orbital devices rotating around Mars to get an idea of \u200b\u200bthe geology of the mounds. On the orbital devices there are sensors, cameras and other scientific devices collecting a number of data.

From afar, the mounds seem like each other, but the images with high resolution made by orbital devices allowed scientists to increase the scale and see an incredible variety of structures.

Cleaning layers of rocks in the mounds, abundant by clay, indicate that on the surface of Mars there was a large amount of water that entered a chemical reaction with stones.

Water, both in liquid and in ice form, could cause erosion due to penetration into cracks in the rocks.

According to scientists, the majority of evidence that there were stormy rivers and lakes on Mars - it was destroyed, so now it is difficult to say what type of water caused erosion.

" We can collect part of the story together, but we will leave most for the interpretation, ”he adds.

However, a robotics study of this region can determine whether the ocean has ever existed, and whether there could be life in it.
