Martian mudstones contain features that NASA says are the "clearest sign of life" yet on Mars, according to new findings from NASA’s Perseverance rover released Sept. 10.

NASA's Mars rover Perseverance has uncovered rocks in a dry river channel that may hold potential signs of ancient microscopic life.

Minerals in the rock might have been produced by microbes in chemical reactions, but researchers say they’ll need to examine the sample more closely to know for sure

"The idea was for our payload to get us just up to the potential biosignature designation and have the rest of the story told by instruments here on Earth."

Ancient organisms may have left microscopic "biosignatures" on Mars. That's according to NASA scientists, who say a rock sample offers the most concrete proof yet that the red planet once hosted life.

An exciting discovery on Mars is being overshadowed by turmoil at NASA, with budget cuts threatening to destroy a scientific legacy that has been built over decades. Yesterday, the agency shared a finding, published in Nature, of potential biosignatures identified by the Mars Perseverance rover in a 3.5 billion-year-old rock.
