Keith’s note: I will make this simple: did NASA find clear evidence of life on Mars? No. Did NASA find an interesting rock feature that might signal or indicate that there was once life on Mars? Yes. Is this a final answer? No. Not by any means. Much, much more work needs to be done. That is one of the main reasons why advanced in situ instrumentation on landers and eventual sample return missions are needed. Just remember: on Earth there are many things that look like life that are not – and there are many things that are alive that look like rocks. And that’s on Earth. What happens on Mars may be totally different. Or not. Let’s go find out more. Full story: Mars Perseverance Rover Imagery Of A Rock With Possible Biosignatures
