NASA Believes It Has Found Evidence Of Life On Mars

NASA has spotted some signs of life on Mars as the Curiosity rover brought back acceptable supporting evidence. The Rocks collected by the rover are reviewed by NASA scientists. The experts believe that the rocks hold some bug-originated organic carbon. The official aeronautics and space setup has investigated the sediment from six different locations and got a sight of an ancient carbon cycle. The report about the current findings was published in the Proceedings of the National Academy of Sciences journal on January 18, 2022.



Paul Mahaffy, the principal investigator of the Sample Analysis at Mars (SAM) chemistry lab aboard Curiosity commented,



“We’re finding things on Mars that are tantalizingly interesting, but we would really need more evidence to say we’ve identified life,”. “So we’re looking at what else could have caused the carbon signature we’re seeing, if not life.”



NASA supposed that the samples could have a 'biological basis'.The carbon residue resembles fossilized vestiges of microbial life that have been found in Australia.



The lead author of the study from Penn State University in the US, Professor Christopher House, told The Metro: "The samples extremely depleted in carbon 13 are a little like samples from Australia taken from sediment that was 2.7 billion years old."




In addition, Scientists at the Physical Research Laboratory in Ahmedabad have also noted thousands of tracks on the surface created by tumbling boulders. These boulder tracks hint at the recent seismic activity on Mars.



Dr S Vijayan, Assistant Professor with the Planetary Science Division at the Physical Research Laboratory, led the research at Ahmedabad, scientist commented, "Mars is currently active,"



The study is published in Geophysical Research Letters. According to the concept, it takes about two to four Martian years (four to eight Earth years) for these boulder tracks to disappear. These ejections could direct the investigation of biological processes on planetary surfaces.
