The rover robot Perseverance on the surface of Mars has reached an essential stage of its research mission For traces of life on the red planet, he collected samples that are “the most valuable” to date for containing them Possible bio-fingerprints that must be confirmed by analyzes conducted on the ground, according to what the US space agency announced ( NASA) Thursday. Although this discovery does not constitute evidence that life previously existed on Mars, it is It represents the best chance to date to one day be able to detect past microbial life. The potential biometric imprint may result from the presence of life, but it may also occur with the absence of life. To confirm this biometric signature, samples must be analyzed with powerful laboratory tools on Earth. NASA plans to send the samples back to Earth via a new mission it will launch by 2033. “We can say it’s more,” David Schuster, who is working on the samples, told a news conference Rock samples of importance have ever been collected.” Two samples were taken as a result of drilling operations in a rock called “Wildcat Ridge” about one meter high. It is located in a delta formed about 3 , 5 billion years old at the confluence of an ancient river and lake. The importance of this rock stems especially from the fact that it is a sedimentary rock that appears to have been formed when water evaporated from the lake . After conducting a separate analysis of the rock by means of a tool installed on the arm of “Perseverance”, the results showed the presence of Organic compounds are the most abundant discovered since the mission began a year and a half ago.
