The collisions of asteroids with the Red Planet 11 million years ago caused pieces of meteorites to blow up the surface of the planets and throw themselves into space. A group of these meteors fell to Earth in 1911, the first to be in Egypt and were called invasions. These raids revealed that there was once flowing water beneath the surface of the Red Planets.
Planetary scientists at the University of Glasgow use a technique to analyze these cosmic rocks, claiming that they shed light on the process it generates, potentially giving live liquid water to Mars.
Glasgow University Researcher Dr. Luc Dali says: "There is a huge amount of information about Mars locked inside the small pieces of the red planet that have fallen to Earth like meteorites. [1
An analysis of invasions revealed that Martian cosmic rocks were formed upon impact. on the planet of two asteroids, the first about 633 million years ago and the second about 11 million years ago.
The first formed a massive crater of volcanic rock on the Martian surface.
Dr. Dali said: "This impact was large enough and hot enough to melt the ice below the surface of Martian and send it to rush through newly formed cracks in the rock.
"Effectively forms a temporary hydrothermal system beneath the surface of Mars that changes the composition of minerals in the rocks near these cracks.
"This suggests that the asteroid impact was the secret mechanism for the generation of liquid water in raids long after the volcano that formed them on Mars had disappeared. "

Dr. Dali said," We are currently trying to understand Martian geology through these meteorites, without knowing what part of the surface of Mars these so-called invasions originate.
"Our new discoveries greatly limit the possible origin of invasions.
"We now know that we are looking for a complex volcanic building, about 1.3-1.4 Billi per year, with one crater about 633 million years old and another about 11 million years old. "
He added:" Very few places on Mars can fit this bill.
"It's part of the interplanetary detective work that is still going on, but we tend to break the case."
NASA spacecraft sent the Curiosity Rover rover to the Red Planet in 2011 to try to find out if Mars had the right environmental conditions to sustain alien life.
At the beginning of its mission, the unmanned probe noticed chemical and mineral signs of past common Mars environments.
NASA actually declared evidence of liquid water on Mars in 2015.
The space agency said in a statement: Dark, narrow, 100-meter-long strips called repeated sloping lines running down Mars are believed to be formed by modern running water.
"Recently, planetary scientists discovered hydrated salts along these slopes in Hale Crater, confirming their original hypothesis that the streaks are indeed formed by liquid water. ”
