NASA’s Perseverance rover has found rocks in a dry river channel on Mars that may show signs of ancient life. The samples, taken from Neretva Vallis, contained iron phosphate and iron sulfide, chemicals often linked to microbial activity on Earth. Scientists said it is the strongest evidence yet but warned that non-biological processes could also explain the results. The rover has collected 30 samples so far, with more planned. NASA hopes one day to return them to Earth, though delays have pushed the mission into the 2040s. Researchers called the find “exciting” but not final proof of life. (PC: X)
