NASA\u2019s Perseverance rover has identified its most compelling evidence yet for ancient microbial life on Mars.<\/p>\n

A rock sample dubbed \u201cSapphire Canyon,\u201d collected from the Bright Angel formation in Jezero Crater, shows mineral and chemical patterns that resemble biosignatures\u2014possible traces of past microbial activity. These \u201cleopard spots,\u201d rich in iron-based minerals, could have been formed by microbial metabolisms, though non-biological processes can\u2019t be fully ruled out.<\/p>\n

Possible Signs of Ancient Martian Life<\/p>\n

A rock sample gathered by NASA\u2019s Perseverance rover in an ancient riverbed within Jezero Crater may hold evidence of past microbial life. The sample, known as \u201cSapphire Canyon,\u201d was collected in 2024 from a rock called \u201cCheyava Falls\u201d and is now considered one of the mission\u2019s strongest candidates for containing potential biosignatures, according to research published today in the journal Nature.<\/p>\n

Scientists define a potential biosignature as a material or structure that could have been formed by biological activity, but which still requires more investigation before confirming or ruling out a link to life.<\/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

Exploring Jezero Crater\u2019s Bright Angel Formation<\/p>\n

In July 2024, Perseverance reached Cheyava Falls<\/a> while studying the \u201cBright Angel\u201d formation, a series of rocky outcrops along both sides of Neretva Vallis, a river valley about a quarter-mile (400 meters) wide that was carved long ago by water flowing into Jezero Crater.<\/p>\n

\u201cThis finding is the direct result of NASA\u2019s effort to strategically plan, develop, and execute a mission able to deliver exactly this type of science \u2014 the identification of a potential biosignature on Mars,\u201d said Nicky Fox, associate administrator, Science Mission Directorate at NASA Headquarters in Washington. \u201cWith the publication of this peer-reviewed result, NASA makes this data available to the wider science community for further study to confirm or refute its biological potential.\u201d<\/p>\n

\nSedimentary Rocks Rich in Organic Material<\/p>\n

The rover\u2019s science instruments found that the formation\u2019s sedimentary rocks are composed of clay and silt, which, on Earth, are excellent preservers of past microbial life. They are also rich in organic carbon, sulfur, oxidized iron (rust), and phosphorus.<\/p>\n

\u201cThe combination of chemical compounds we found in the Bright Angel formation could have been a rich source of energy for microbial metabolisms,\u201d said Perseverance scientist Joel Hurowitz of Stony Brook University, New York, and lead author of the paper. \u201cBut just because we saw all these compelling chemical signatures in the data didn\u2019t mean we had a potential biosignature. We needed to analyze what that data could mean.\u201d<\/p>\n

\nStrange Spots and Chemical Fingerprints<\/p>\n

First to collect data on this rock were Perseverance\u2019s PIXL<\/a> (Planetary Instrument for X-ray Lithochemistry) and SHERLOC<\/a> (Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals) instruments. While investigating Cheyava Falls, an arrowhead-shaped rock measuring 3.2 feet by 2 feet (1 meter by 0.6 meters), they found what appeared to be colorful spots. The spots on the rock could have been left behind by microbial life if it had used the raw ingredients, the organic carbon, sulfur, and phosphorus, in the rock as an energy source.<\/p>\n

Leopard Spots: Clues in Mineral Patterns<\/p>\n

In higher-resolution images, the instruments found a distinct pattern of minerals arranged into reaction fronts (points of contact where chemical and physical reactions occur) the team called leopard spots. The spots carried the signature of two iron-rich minerals: vivianite (hydrated iron phosphate) and greigite (iron sulfide). Vivianite is frequently found on Earth in sediments, peat bogs, and around decaying organic matter. Similarly, certain forms of microbial life on Earth can produce greigite.<\/p>\n

The combination of these minerals, which appear to have formed by electron-transfer reactions between the sediment and organic matter, is a potential fingerprint for microbial life, which would use these reactions to produce energy for growth. The minerals also can be generated abiotically, or without the presence of life. Hence, there are ways to produce them without biological reactions, including sustained high temperatures, acidic conditions, and binding by organic compounds. However, the rocks at Bright Angel do not show evidence that they experienced high temperatures or acidic conditions, and it is unknown whether the organic compounds present would\u2019ve been capable of catalyzing the reaction at low temperatures.<\/p>\n

Implications for Mars\u2019 Habitability Timeline<\/p>\n

The discovery was particularly surprising because it involves some of the youngest sedimentary rocks the mission has investigated. An earlier hypothesis assumed signs of ancient life would be confined to older rock formations. This finding suggests that Mars could have been habitable for a longer period or later in the planet\u2019s history than previously thought, and that older rocks also might hold signs of life that are simply harder to detect.<\/p>\n

\nExtraordinary Evidence Needed<\/p>\n

\u201cAstrobiological claims, particularly those related to the potential discovery of past extraterrestrial life, require extraordinary evidence,\u201d said Katie Stack Morgan, Perseverance\u2019s project scientist at NASA\u2019s Jet Propulsion Laboratory in Southern California. \u201cGetting such a significant finding as a potential biosignature on Mars into a peer-reviewed publication is a crucial step in the scientific process because it ensures the rigor, validity, and significance of our results. And while abiotic explanations for what we see at Bright Angel are less likely given the paper\u2019s findings, we cannot rule them out.\u201d<\/p>\n

The scientific community uses tools and frameworks like the CoLD scale and Standards of Evidence<\/a> to assess whether data related to the search for life actually answers the question, Are we alone? Such tools help improve understanding of how much confidence to place in data suggesting a possible signal of life found outside our own planet.<\/p>\n

Perseverance\u2019s Growing Rock Collection<\/p>\n

Sapphire Canyon is one of 27 rock cores<\/a> the rover has collected since landing at Jezero Crater in February 2021. Among the suite of science instruments is a weather station that provides environmental information for future human missions, as well as swatches of spacesuit material<\/a> so that NASA can study how it fares on Mars.<\/p>\n
