Asteroid impact created a tsunami of destructive force on Mars

According to the Journal of Geophysical Research: Planets, an international team of scientists from France, Spain and Australia came to the conclusion that about three billion years ago, the red planet was under the influence of a huge catastrophe, the main cause of which was water. A huge wave at the height of a ten-story house swept across the entire area of ​​the planet at a speed of 60 meters per second. What happened after that, almost all water on Mars just evaporated?

Despite the fact that most of the liquid on the planet is currently concentrated under the poles of Mars, in the past the planet has been more comfortable for life than Earth. According to the latest data, old Mars had a huge ocean that exceeded the size of the Arctic Ocean. The depth of such a water reservoir would reach 2 kilometers and its water reserves would be sufficient to cover the entire surface of the planet with a layer of 130 meters.

Is Lomonosov to blame for everything?

The mystery of the disappearance of such a large amount of water is still very urgent for scientists from all over the world. However, a new study can reveal the truth about such a mysterious phenomenon by combining two completely different witnesses of an ancient event of planetary proportions: the traces of the ancient ocean that have survived to this day, and the Lomonosov crater, whose diameter is 150 Kilometers exceeds.

According to the study, the age of the crater agrees with the age of the marshes similar to those on Earth due to the effects of the tsunami. In addition, the asteroid, which caused the appearance of a huge wave, should fall to the bottom of the ocean, as the preserved shape of the crater shows.

Most likely, the Mars tsunami could have a reddish hue as there was already a large amount of dust on Mars at that distant time.

Old Mars contained even more water than planet Earth

It is very difficult to answer the question of how and why the red planet has had large amounts of water in the past. This rough and dusty world receives one-third less solar heat than the earth, and Mars's weak gravity would not allow significant liquid water reserves. The only thing hypothetical researchers could find on such a planet would be ice. However, according to the latest models, scientists have found that ancient Mars is likely to have a hydrogen atmosphere that allows it to retain water in the liquid phase due to a fairly favorable surface climate.

To date, Mars has lost most of its water resources. The remnants of the former wealth exist today only in the form of several underground lakes, and on the surface of the planet occurs only occasionally liquid water.
