The diligent rover confirms the existence of a large lake on Mars

On target! By selecting the Jesero abyss for dangerous arrival Tuesday Rover
Perseverance On February 18, 2021, NASA and all researchers collaborated on this mission, aiming to target an ancient lake area suitable for searching for clues to life, based on satellite imagery. The first results sent by the Mars robot were released in a review on Thursday Science, Make sure they had the talent: the crater owes its shape to “a diameter of about 35 km” and a great length of 3.6 billion years ago.

This firmness is thanks to the images sent by the Super Game, a sophisticated tool built in Toulouse and serves as the rover’s homing head. Thanks to him, I was able to notice the details “less than 10 centimeters” by diligence. Furthermore, according to a study by CNRS geologist Nicholas Mangold of the Laboratory of Geology and Geomorphology, the “sloping sedimentary layer between the horizontal layers found in Jessaro” actually has a geometry “common to the deltas on Earth”.

“We are in the right place”

“We were expecting a little of this pleasant surprise, and there we promised it,” replied Sylvester Maurice, of the Toulouse Planetology Institute for Research in the Cradle of Supercom, Astronomical Physics. “We now know that we are in the right place and that it is best to look for traces of life there,” the researcher exclaims. Clay and sand sediments are actually “very good candidates” for finding any organic matter.

The images revealed large pebbles and large boulders across a meter, witnessing “strong river currents” and probably “major climate change”, the nature of which has not yet been determined. Larger rocks can provide “fragments of the Martian surface”.

Gesero will reveal its ultimate secrets only when samples – sediment or crust – are analyzed on Earth by 2030. This will enable us to select the most interesting models to be recovered from the journey to Mars in 2026, ”explains Sylvester Maurice.

For events, this “Lake of Promises” opened on the entire “solar link” of Mars, a period of about two weeks, which returns every two years, and the Sun intervenes between the Red Planet and the Earth. Unable to communicate with Mars instruments.
