The Perseverance rover has made very interesting discoveries in the place where it is located exploring Mars, the crater of Jezero. What was found is important to help understand more about this region and its geological history.
The two main discoveries have to do with the presence of water in the rocks, the beginnings left and the organic molecules found. After all, was there a vast ocean on the planet or not?
New evidence for the existence of water in the soil of Mars
These organic molecules can be created through biological or non-biological processes, so they are not a confirmation that life existed there, but they are a good sign that, if life once existed there, it should be possible to find evidence of this fact.
In addition, the team found that the rocks in the crater are igneous, having formed from lava flows or magma. This answers a big question about the crater's composition, as researchers were previously unsure whether the rocks there were igneous or sedimentary.
I was beginning to despair that we would never find the answer. Then our PIXL instrument got a good look at the abrupt smudge of a rock in the zone dubbed 'South Séitah,' and it all became clear: the crystals inside the rock provided the smoking weapon."
The PIXL, or X-Ray Planetary Lithochemistry Instrument, uses X-rays to analyze rocks and determine their composition. The use of PIXL in a particular sample called "Brac" showed a distinct structure that indicated igneous rock.
A good geology student will tell you that such a texture indicates that the rock formed when the crystals grew and settled in a slowly cooling magma - for example, a thick lava flow, lava lake, or magma chamber.
