Simulations show that the Red Planet, Mars, is even more ancient than scientists first believed. The new simulations were done based on the cause that created the mixed Mars mantle in the early years of the development of our Solar System.
While the Red Planet was forming in the Solar System, it was also hit continuously by planetesimals. What are planetesimals? They are solid objects from space coming together with many others under gravitation to form a planet, in this case, becoming Mars’ moons, which are called Phobos and Deimos.
Scientists recreated the impact produced during the red planet’s creation. They also simulated the planetesimals attack by combining materials and computer programs; therefore, helping them to assess roughly how old Mars actually is. The materials used for this experiment are similar to the red planet’s nature as well as pieces of the space matter.
Mars is much younger than initially thought
The research about the formation of Mars relates to our planet as well. This gives scientists that study Earth a few more details on the history of our world. So far, 61,000 meteorites have been discovered on the Earth’s surface. About 200 of these found meteorites are presumed to be originated from the formation of Mars due to the collisions from the planetesimals.
“Based on our model, early collisions produce a heterogeneous, marble-cake-like Martian mantle. These results suggest that the prevailing view of Mars formation may be biased by the limited number of meteorites available for study,” said Dr. Simone Marchi, lead researcher from the Southwest Research Institute.
Previously, scientists’ view on the formation of the Red Planet was that it took form about some 2-4 million years after the Solar System began to form. However, this new study reveals that Mars may have been formed 20 million years after the Solar System started to form.
