Detecting Fossilized Life on Mars

“This should be an easy form of fossilized life for a rover to detect on other planets. If we see this kind of extensive filamentous rock on other planets, we would know it’s a fingerprint of life,” said University of Illinois geology professor Bruce Fouke, who led a new, NASA-funded study of bacterium that controls the formation of such rocks on Earth that thrives in harsh environments similar to harsh conditions on Mars. “It’s big and it’s unique. No other rocks look like this. It would be definitive evidence of the presences of alien microbes.”
