The rover Perseverance of NASA who landed in planor Mars on February 18, is located at a diameter of 45 km. Jezero crater, in which there was a lake which supplied the water of one or more rivers, even creating a delta. This means that the chances are that some life forms had developed there. Now, the rover prepares to collect the first samples of rocks on Mars, while the scientists of the mission have evidence of ancient floods in the dry bed of the lake in which it landed. Basic target of NASA's mission is locating a trace of the existence of life, albeit microbial, in the distant past of the Red Planet.
The milestone is expected to take place within two weeks in a scientifically interesting area of the crater Lake called Cratered Floor Fractured Rough.
He had to spend some time testing the instruments and systems of the rover, while in the meantime the mission of Perseverance passed into the background, since the flights of the drone he was carrying had to take place. According to NASA, the rover is finally starting the basic stage of its mission and is ready to collect and analyze, then, the first sample from a rock in the area where it is located.
The rover will start collecting rocks which it will analyze with the instruments at its disposal. If any of the rocks turn out to be interesting, the rover will drill it to get samples from inside. These samples will be stored by Perseverance and delivered to a next mission scheduled to go to Mars to pick up the samples and bring them back to Earth for study.
In addition to filling in the gaps that exist in understanding the geology of the area, the rover will also look for possible signs of ancient germs.
Initially, it will develop the two-meter-long robotic arm to determine exactly where it will take its sample. He will then use an abrasive tool to scrape the top layer of rock.
These will be analyzed by the scientific instruments placed in the turret of Perseverance, to determine the chemical and mineral composition, and organic matter will be searched.
