Mars is still a mystery to man determined to find water or traces of it on the red planet, so expeditions conducted by the Perseverance robot have resulted in four investigations published in the journal Science. one of the most renowned in the world.
As NASA pointed out in a recent statement on its website, one of those four works has to do with the information Perseverance received from the bottom of Jezero Crater before reaching the river’s ancient delta, also known as Jezero, in April 2022 . A second study, published in the same journal, describes the presence of rock that appears to have formed from a thick body of magma.

The other two articles, published in Science Advances, a subsidiary of Science magazine, describe the unique methods used by Perseverance’s rock evaporation laser and penetrating radar to detect the presence of igneous rock covering the crater floor.
but What are igneous rocks and how important were they in the search for water and perhaps life in the Red Planet’s past?
It turns out that igneous rocks, which form when magma cools and solidifies, are great for measuring the passage of time, which means they will allow scientists, based on studies to be conducted over the coming months, to predict whether a lake of liquid water actually existed in Jezero Crater.
The presence of these rocks is also an indication that Mars has had major volcanic activity millions of years ago in the past, which may be comparable to the major volcanic activity that existed on Earth long ago.
All these signs tell us about the past of Mars, maybe it’s not what scientists expected, who do not exclude having an exact answer for humans about a suitable climate on the red planet, as well as knowing the causes that caused the have planets dry and unable to support any form of life.
