They stressed that in-depth analysis is needed of the sample gathered there by Perseverance — ideally in labs on Earth — before reaching any conclusions.
While acknowledging the latest analysis “certainly is not the final answer,” NASA’s science mission chief Nicky Fox said it’s ”the closest we’ve actually come to discovering ancient life on Mars.”
Roaming Mars since 2021, the rover cannot directly detect life, past or present. Instead, it carries a drill to penetrate rocks and tubes to hold the samples gathered from places judged most suitable for hosting life billions of years ago. The samples are awaiting retrieval to Earth — an ambitious plan that’s on hold as NASA seeks cheaper, quicker options.
Calling it an “exciting discovery,” a pair of scientists who were not involved in the study — SETI Institute’s Janice Bishop and the University of Massachusetts Amherst’s Mario Parente — were quick to point out that non-biological processes could be responsible.
