NASA’s Perseverance rover studied mudstones in Jezero Crater and found macromolecular carbon in two rocks, Cheyava Falls and Walhalla Glades. The carbon shows similarities to Earth carbon from both biotic and abiotic processes, offering clues about Mars’ ancient habitability but not proof of life; scientists say sample return to Earth is needed for definitive testing.
NASA’s Mars Reconnaissance Orbiter captured Perseverance finishing the 26.2-mile Martian marathon in Jezero Crater on June 14, 2026, a milestone that accompanies the rover’s ongoing science—imagery, samples and potential biosignatures—with a orbital perspective on its continued exploration; nearby, Opportunity also reached marathon distance in more than a decade of driving.
NASA's Perseverance rover completed a Martian marathon by driving 42.195 km in about five years and four months, a milestone visible in a HiRISE image from Mars orbit that shows the rover as a blue‑green dot with its looping wheel tracks near Jezero Crater.
Perseverance drilled Cheyava Falls in a Jezero Crater mudstone and found organic carbon intertwined with iron-rich minerals forming “poppy seeds” and “leopard spots.” The minerals, vivianite (iron phosphate) and greigite (iron sulfide), are often linked to microbial activity on Earth, but abiotic processes could explain them too. While the finding is intriguing and helps contextualize ancient Martian habitability, it stops short of life detection and highlights the need for detailed terrestrial analysis of returned samples.
NASA’s Perseverance rover has found the highest concentration of complex organic molecules to date in Jezero crater, hinting at past microbial life on Mars; JWST observations show early galaxies forming and dying quickly, a newborn star was seen in Orion, and Euclid produced the Milky Way’s most detailed image yet. In paleoanthropology, nearly two dozen Homo naledi skeletons from Rising Star cave are all female. Closer to home, AI-assisted research adds support to the idea that water may consist of two interconverting liquids.
NASA’s Perseverance rover detected macromolecular carbon (MMC), a complex organic matter, in two Bright Angel mudstones at Jezero crater using the SHERLOC instrument, marking the most robust organic signal there to date and the first MMC identified on Martian rock surfaces. While intriguing, MMC can form through both biological and non-biological processes, so this does not prove past life; definitive testing would require returning samples to Earth, a plan hampered by political issues. Curiosity has also found organics elsewhere on Mars, underscoring ongoing interest in whether ancient microbes once inhabited the planet.
NASA's Perseverance rover detected hundreds of organic detections and macromolecular carbon in two mudstones from Jezero Crater's Bright Angel formation, the strongest organic evidence yet from that site. The carbon's origin—biological or abiotic—remains unclear and will require Earth-based analysis of samples Perseverance is collecting for eventual return under NASA's Mars Sample Return program, with a possible window from 2035 to 2039. This finding builds on earlier Curiosity results, suggesting ancient Mars had the chemistry to support life.
Analysis of Martian rock Cheyava Falls by Perseverance’s SHERLOC and WATSON detected macromolecular carbon, a potential sign of ancient organics and past habitability in Jezero Crater; but MMCs can form abiotically, so a definitive conclusion requires returning samples to Earth—an effort whose future remains uncertain amid stalled Mars Sample Return plans.
NASA’s Perseverance rover found macromolecular carbon in the Bright Angel outcrop at Jezero Crater—the highest concentration of organic molecules detected on Mars to date. SHERLOC mapping and comparisons with Curiosity’s Gale crater data link the carbon to ancient, water-rich conditions and potential habitability, but the finding is not proof of life; a definitive biosignature would require future samples or more data.
NASA’s Perseverance rover detected hundreds of organic macromolecules inside two mudstones in Jezero Crater using SHERLOC, marking the strongest organic signal yet from Martian rocks. While the findings boost the possibility that ancient Mars could have hosted life, scientists caution the carbon could also form through non-biological processes, and the rover’s instruments can’t confirm biotic origin. The study, published in Science Advances, complements a prior potential biosignature at Cheyava Falls and suggests organics may have been widespread on early Mars, though more testing and sample return are needed.
NASA's Perseverance rover found a 1‑meter rock core from Cheyava Falls at Bright Angel in Jezero Crater showing leopard-spot textures and minerals like vivianite and greigite, indicating ancient water and redox chemistry that could feed microbes. While this is among the strongest potential biosignatures yet, it is not proof of life and abiotic explanations cannot be ruled out; further Earth-based analyses on returned samples are needed.
NASA's Mars Reconnaissance Orbiter captured its 100,000th image of the Red Planet with the HiRISE camera, showcasing the Syrtis Major region near Jezero Crater and highlighting the mission's ongoing role in tracking Mars’ changing surface, with public input via the HiWish project.
NASA’s Perseverance rover is nearing a 42.195-kilometer milestone on Mars, having traversed the Jezero Crater region for five years. It’s studying ancient rocks at Lac de Charmes, including the Arathusa outcrop, to uncover some of the planet’s oldest geology, such as megabreccia from a ~3.9-billion-year-old Isidis Planitia impact and possible volcanic features, with plans to push toward Gardevarri and Singing Canyon as the mission continues its ultramarathon-style exploration.
NASA’s Perseverance has driven more than 26.05 miles (41.92 km) on Mars over five years, closing in on Opportunity’s 28.06-mile record. After leaving Jezero Crater, it’s pushing into Lac de Charmes with future stops like Gardevarri and Singing Canyon, inching toward what could become the rover’s ultramarathon finish line later this month.
NASA’s Perseverance posted its sixth selfie from Mars, taken from the Lac de Charmes region west of Jezero Crater and assembled from 61 images by the WATSON camera as the rover continues its westward trek. In addition, a 46‑image Mastcam-Z panorama of the Arbot area provides a detailed look at ancient rock formations, including megabreccia tied to a 3.9‑billion‑year‑old Isidis Planitia impact, helping scientists study the oldest rocks the mission will examine.
