Perseverance Finds Organic Carbon Preserved Just Beneath the Martian Surface

Perseverance has found shallow preserved organic carbon on Mars, raising new questions about ancient Martian environments. Mars keeps offering clues that are promising enough to study, but not definitive enough to settle the biggest question. In September of last year, NASA reported that its Perseverance rover had found a potential biosignature, a substance or structure that could have a biological origin. Now, a new paper published in Science Advances has confirmed the presence of organic carbon in the same two Bright Angel formation rocks, giving scientists a clearer view of what was detected and what still cannot be concluded.
