NASA's Perseverance Rover Discovers Potential Biosignature on Mars
NASA's Perseverance rover, which landed in Jezero Crater on Mars in February 2021, discovered a potential biosignature in a sample from an ancient dry riverbed. The sample, named 'Sapphire Canyon,' was collected from a rock called Cheyava Falls in July 2024. This finding, detailed in a peer-reviewed paper in the journal Nature, suggests the presence of chemical compounds that could have supported microbial life. Acting NASA Administrator Sean Duffy emphasized the significance of this discovery, noting it is the clearest sign of life ever found on Mars, though further study is needed to confirm its biological origin. The discovery indicates that Mars may have been habitable for a longer period than previously thought.
