A sample collected by NASA\u2019s Perseverance Mars rover from an ancient dry riverbed in Jezero Crater could preserve evidence of ancient microbial life. Taken from a rock named \u201cCheyava Falls\u201d last year, the sample, called \u201cSapphire Canyon,\u201d contains potential biosignatures, according to a paper<\/a> published Wednesday in the journal Nature.<\/p>\n

A potential biosignature<\/a> is a substance or structure that might have a biological origin but requires more data or further study before a conclusion can be reached about the absence or presence of life. \u00a0<\/p>\n

\u201cThis finding by Perseverance, launched under President Trump in his first term, is the closest we have ever come to discovering life on Mars. The identification of a potential biosignature on the Red Planet is a groundbreaking discovery, and one that will advance our understanding of Mars,\u201d said acting NASA Administrator Sean Duffy. \u201cNASA\u2019s commitment to conducting Gold Standard Science will continue as we pursue our goal of putting American boots on Mars\u2019 rocky soil.\u201d<\/p>\n

NASA\u2019s Perseverance rover discovered leopard spots on a reddish rock nicknamed \u201cCheyava Falls\u201d in Mars\u2019 Jezero Crater in July 2024. Scientists think the spots may indicate that, billions of years ago, the chemical reactions in this rock could have supported microbial life; other explanations are being considered.<\/div>\n
