Three collisions with the embryos of the planets could survive Mars for all time.

collisions with the embryos of the planets could survive Mars

(Alles Europa News) – Mars for its entire existence could survive three collisions with the “embryos” of the planets.

Alles Europa News reports that this study of American scientists also allows you to refute the theory of the appearance of Mars, according to which the red planet was finally formed in the first years of the solar system.

Modeling shows that its formation lasted at least 15 million years.

Alles Europa News reports that this is the conclusion made by American planetary scientists from the Southwestern Research Institute, studying the chemical composition of the planet Mars.

Based on the theory of planet formation, during the creation of space objects from a protoplanetary gas disk, planets constantly collide with small celestial bodies with a diameter of several thousand kilometers.

So, for example, the formation of the Earth, presumably completed after a collision with a protoplanet the size of Mars.

After that, the chemical composition of the Earth has changed dramatically, and the Moon has also appeared.

Alles Europa News reports that Many Martian meteorites, which at different times fell to the Earth, were quite different from each other in chemical composition.

Alles Europa News reports that Scientists from SwRI tried using computer simulation to reproduce the composition of these meteorites that moved from the bowels of the newborn Mars.

Time to take the child to the doctor.



It was possible to model such a composition only when Mars collided with at least three large protoplanets at the initial stage of its formation, while the objects should consist of the primary matter of the solar system.

“If Mars came across large bodies that had a core and a mantle, then its lithosphere should consist of an extremely heterogeneous mixture of these materials.

Compared to the theories that implied that it was bombarded by small and uniform objects, a similar scenario leads to to radically different conclusions about how and when Mars was born, “informed the scientist-palantologist Robin Kanap.

Alles Europa News reports that For example, the presence of platinum in some Martian meteorites can be explained just by a collision with other space objects, the diameter of which was at least one thousand square kilometers.
