American space agency rover, NASA, sustainability, launches its scientific mission, writes portal Fox News.
Rover In February, it landed in the crater of Jessero, which until recently served as a communication center between Earth lead and helicopter drone ingenuity. But now he has returned to his scientific mission, viz Discover the ecological history of the planet and find signs of life. Through the Perseverance Mission, scientists want to create a timeline for the formation and drying up of a lake that existed in a crater billions of years ago.
The rover uses a Watson mechanical arm for the job (pozn. redakcie: Wide angle topographic sensor for operations and engineering). With his help, the rover was able to capture detailed images of the rocks on Mars. NASA says its goal is to find out if the rocks on Mars are debris or caused by volcanic activity.
According to experts, magmatic rocks are an excellent “geological clock”, thanks to which scientists can create a more accurate timeline of the expansion of the crater. On the other hand, sedimentary rocks are a more suitable material for preserving biological footprints. The Perseverance Mechanical Rover arm uses a grinder to remove the surface of the rocks Revealed their internal structure.

“If you look at a rock, you see its story,” says perseverance scientist Ken Farley.
Was there life on Mars?
The question of life on Mars has plagued scientists for years. Evidence suggests that in the past, the red planet may have been a completely different place than it is today. It is assumed Mars had a hot climate, dense atmosphere and water. Some theorize that there may be an ocean and even life on Mars.
If Mars had ever been habitable, it would have been a very short time window. This means that despite the existence of life on this planet, he did not have enough time to evolve into more complex creatures. If Rover Perseverance manages to find traces of life in the crater lake, it is assumed It will be about the life of microorganisms. The lake is an unusual place in this case. Scientists speculate that there may have been a lake here when Mars was a humid place billions of years ago.
They also appear Evidence of various minerals brought to the crater lake by the surrounding rivers. This will create a favorable environment for microorganisms. Scientists also claim that Lake Crater is a place where life could have been found on Mars if it had ever existed. If I travel with perseverance Signs of life could be found, This would be the greatest discovery in human history.
