!Big discovery... NASA confirms the existence of water on Mars
If water exists, then the existence of life on the red planet is very possible
The Curiosity robot, chartered on Mars by NASA, discovered traces of water ripples on rocks on the red planet. According to a press release from the agency published on February 8, this discovery is the best proof that lakes could have existed there.
“This is the best water and wave evidence we have seen in the entire mission. NASA scientists are not overreacting to determine the significance of the discovery that the Curiosity robot recently made on the planet Mars.
And for good reason, while exploring the Martian soil, he discovered on rocks the trace of “old water ripples”, which constitute, according to NASA, the best proof that lakes existed on the red planet.
“We have never found better clues”
?But why are these "wavy textures left in the rock" discovered by Curiosity proof of the existence of a body of water
“Billions of years ago, waves on the surface of a shallow lake agitated the sediments at the bottom of the lake, over time creating wavy textures left in the rock”, details NASA, to explain the process of formation of these ripples. “We drove through miles of lake deposits and never found better clues. »
This discovery is all the more important as it took place in a region that scientists had until now considered to be much drier than the former presence of this lake would now suggest. Report West France.
