There are three possible explanations for the new find, and one involves ancient Mars microbes.
NASA's Curiosity Mars rover used two different cameras to create this selfie in front of a rock outcrop named Mont Mercou, which stands 20 feet tall.
"We're finding things on Mars that are tantalizingly interesting, but we would really need more evidence to say we've identified life," Paul Mahaffy, who served as the principal investigator of Curiosity's Sample Analysis at Mars chemistry lab until retiring from NASA's Goddard Space Flight Center in Greenbelt, Maryland, in December 2021,RelatedThis mosaic was made from images taken by the Mast Camera aboard NASA’s Curiosity rover on the 2,729th Martian day, or sol, of...
The researchers came up with three possible explanations for the intriguing carbon signal. The first involves Mars microbes producing methane, which was then converted into more complex organic molecules after interacting with ultraviolet light in the Red Planet air. These larger organics then fell back to the ground and were incorporated into the rocks that Curiosity sampled.
