NASA Says Perseverance's 'Sapphire Canyon' Sample Holds Potential Biosignature
- On July 21, 2024, NASA's Perseverance rover drilled into Cheyava Falls in Jezero Crater, Mars, and collected its 25th sample named Sapphire Canyon.
- This event followed Perseverance's exploration of Jezero Crater since February 2021, aiming to find potential signs of ancient life in clay-rich, mudstone rocks of Neretva Vallis.
- Researchers identified iron phosphate and sulfide nodules linked with organic carbon, suggesting complex low-temperature redox reactions that might indicate biological processes or non-biological chemistry.
- Lead researcher Joel Hurowitz said, "We can't go so far as to say, 'A-ha, this is proof positive of life,'" while Janice Bishop and Mario Parente highlighted the need to rule out non-biological explanations.
- NASA's Mars Sample Return program plans to retrieve these samples for Earth-based lab analysis, but budget and priorities put the mission on hold, delaying definitive life confirmation.

NASA finds new evidence of potential ancient life on Mars
NASA scientists have discovered compelling new evidence indicating that Mars might once have supported life, similar to that which exists on Earth today. On September 10, 2025, NASA announced new findings from a sample called ‘Sapphire Canyon’, collected by the Perseverance Mars rover from a rock named ‘Cheyava Falls’ on the Red Planet in July 2024. After a year of analysis, scientists have confirmed that the sample contains a “potential biosi…
NASA says a rock sample collected by its Perseverance Mars rover in Jezero Crater may contain evidence of ancient microbial life on Mars. The rover discovered a rock called Cheyava Falls in July 2024. The sample, called Sapphire Canyon, shows what scientists describe as “potential” biofissures — substances or structures that may have a biological origin but require more study. The findings were published in the journal Nature. Acting NASA Admini…
This is indicated by a stone collected by the Mars Rover "Perseverance" last year. Experts say that a biological origin of these traces would be the best explanation.
