Jezero Clues Hint at Possible Microbial Metabolisms, but No Definitive Biosignature (Confidence Level 3)
To the point
Perseverance near Jezero Crater found organics and minerals that could feed ancient microbes, but they don’t prove life and could have non-biological origins, with Level 3 on a seven-level scale, and scientists plan to publish the results and someday bring samples like Sapphire Canyon back to Earth for more sensitive tests to determine their true origins.
