The most evident evidence of the existence of lakes discovered on Mars.

They were identified by Curiosity, the NASA rover which has been on the red planet since 2012 and which over the years has explored large areas of the Gale crater.

According to researchers at NASA's Jet Propulsion Laboratory (Jpl), the latest observations of the rover show the unmistakable traces left by small waves on the shore of ancient lakes that have now disappeared.

"This is the best evidence of water and waves we've seen on the entire mission," said Ashwin Vasavada, a Curiosity chief scientist at JPL.

“With the rover we went up hundreds of meters of lake deposits and we had never seen evidence like this.

Now we have found them in a place that we expected to be dry."

In recent years Curiosity has explored much of the area believed to host large lakes, the presence of which is evidenced by geological formations and chemical compounds of various types.

Climbing the slopes of the large mountain overlooking the crater, the so-called Mount Sharp about 5 kilometers high, the technicians expected that the rover would encounter drier regions.

Surprisingly, however, they found a series of formations that clearly show the marks left by the movement of sandy deposits moved by the waves of an ancient lake.

Traces that also present a particular stratification, perhaps due to cyclical changes in the conditions of the lake.

"Wave ripples, debris flows and rhythmic layers all tell us that the story of wet-to-dry transition on Mars was not a simple one," Vasavada added.

"Mars' ancient climate had a wonderful complexity, just like Earth's."
