NASA’s Perseverance rover has uncovered new evidence that could point to ancient microbial life on Mars after detecting complex organic carbon molecules in rocks from the planet’s Jezero Crater, one of the most closely studied locations in the search for extraterrestrial life
NASA’s Perseverance rover has uncovered new evidence that could point to ancient microbial life on Mars after detecting complex organic carbon molecules in rocks from the planet’s Jezero Crater, one of the most closely studied locations in the search for extraterrestrial life. The discovery was made using the rover’s SHERLOC instrument, which identified macromolecular carbon (MMC) embedded in mudstone rocks at the Bright Angel outcrop along Neretva Vallis, an ancient river channel that once carried water into Jezero Crater billions of years ago. Scientists consider organic carbon an essential building block for life, although its presence alone does not prove that living organisms once existed on the Red Planet. Researchers caution that macromolecular carbon can form through both biological and non-biological processes. It may originate from fossilized microbial matter, but it can also be produced through chemical reactions involving rocks and water or delivered by meteorites striking the Martian surface. The findings add to growing interest in the Bright Angel outcrop, where Perseverance previously discovered unusual spots and mineral formations…
