On the red planet, researchers are still looking for traces of ancient alien life. NASA's Perseverance mission to Mars has accomplished a number of firsts, including the first controlled flight on another planet and the first extraction of oxygen from the Martian atmosphere.
Last year's mission also Jezero CraterIt proved conclusively that the lake was once a large lake. A recent study revealed that these liquids contain large amounts of chemical compounds. According to a study by IFLScience, these discoveries provide compelling evidence that life may once have existed on the red planet.
In February 2021, the NASA Perseverance rover landed on Mars. The rover, who spent his first 208 days on Mars exploring the planet, has presented compelling new evidence that large quantities of organic molecules are common in the lake at Jezero Crater, which was once the rover's landing site.
From IFLScience's Natural History Museum in London, Dr. According to a conversation with Joseph Razzell Hollis, who is also the lead author of a new paper reporting the results, Jezero Crater looks exactly what we suspected based on orbital imaging.
In the past three/three and a half billion years, this was a lake. This is very exciting for us because 3 billion years ago, life began to appear on Earth for the first time. There was also liquid water on Mars.
Then the question comes to mind: “Did the water on Mars also contain the elements necessary for life?”
In a brand new publication in the journal Science, Hollis and Dr. Eva Scheller reported their findings. Using information from the SHERLOC sensor on the Perseverance rover, they studied the rocks in Jezero Crater and found the fluorescence of certain chemical molecules.
According to the researchers, these substances may have contributed to the development of life on Mars. But before they can come to a firm conclusion, they will need to thoroughly examine similar rock samples on Earth.
That's exactly what will happen, as the Mars Sample Return mission, a collaboration between NASA and ESA, develops the technology needed to send samples from Mars to Earth for researchers to study. Space agencies envision doing this in the 2030s.
The Perseverance rover has been studying an ancient river delta thought to feed the lake in Jezero Crater for the past few months. This was chosen as the landing site for the Perseverance rover because it was thought to be a large lake. It was the perfect place to collect specimens that could reveal traces of prehistoric microbial life.
According to a study published in October of last year, Jezero Crater was once a large lake fed by a small river. As the Perseverance and Curiosity rover continues to uncover fascinating discoveries, the search for specimens continues.
