NASA’s Curiosity rover images reveal web-like boxwork ridges on Mount Sharp in Gale Crater likely formed by ancient groundwater, offering new clues about Mars’ wetter past; drilling and mineral analyses show clay minerals and carbonates, helping scientists refine when liquid water could have persisted near the planet’s surface.
NASA's Curiosity rover photos show giant boxwork ridges on Mount Sharp in Gale Crater now covered with hundreds of tiny egg-like nodules. Scientists are unsure how the nodules formed—possible mineral cementation followed by groundwater activity—though there’s no evidence of life. The findings shed light on Mars’ watery past and how ancient groundwater shaped the landscape.
NASA’s Curiosity rover examined boxwork formations on Mount Sharp and found mineral nodules along ridge walls and hollows, formed by ancient groundwater as water flowed through rock cracks. The nodules, plus the height of the groundwater that cemented the ridges, suggest groundwater persisted longer than expected, potentially extending the window for past habitability and microbial life on Mars.
NASA’s Curiosity rover detected organic compounds in a Martian rock sample, raising the possibility that past life could have contributed to these molecules. A Feb. 2026 Astrobiology study argues non-biological processes can’t fully explain the abundance of organics, keeping the door open for life’s past on Mars but stopping short of definitive proof and calling for further study.
NASA's Curiosity rover found long-chain organic molecules on ancient Martian rocks; after evaluating non-biological sources, researchers say those processes can’t easily account for the observed abundances, keeping the possibility of past life on Mars in play but stopping short of a definitive life detection and calling for further Mars-analog research to understand the findings.
Sedimentary rhythmites in Gale Crater's Jura outcrop, analyzed by NASA's Curiosity rover, point to Mars once hosting a much larger moon capable of driving tides in an ancient lake. The proposed moon would have been about 18 times the mass of Phobos and may have been tidally destroyed into rings that later formed Phobos and Deimos. While promising, the evidence isn’t definitive and researchers will inspect additional sites to test the idea.
NASA’s Curiosity rover is carrying out a rare, redesigned three‑stage test using tetramethylammonium hydroxide (TMAH) on Nevado Sajama rock to hunt for carbon‑based molecules that could hint at past life on Mars; after two phases, scientists expect months to interpret the results, building on earlier TMAH work (including a Mary Anning site) and the presence of clay minerals that may help preserve organics.
NASA’s Curiosity rover captured a rare night photo of Mars using its white LEDs with Mastcam (and MAHLI illumination) to light a drill hole nicknamed Nevado Sajama; taken on sol 4740, the image showcases color accuracy under dim Martian lighting and involved long exposure settings.
NASA’s Curiosity rover used onboard LEDs to illuminate the Nevado Sajama drill site at night, with Mastcam and MAHLI capturing details of freshly exposed rock that are hard to see in daylight, including smoother drill walls and subtle layering. This targeted nighttime imaging expands geological insight and demonstrates NASA’s adaptable use of aging hardware to extract high-value data.
NASA’s Curiosity rover, exploring Vera Rubin Ridge in Gale Crater, has identified high concentrations of hematite—an iron-oxide mineral formed in water—raising questions about Mars’ ancient, water-rich environment; the mission also notes unique Martian dunes and continues to study oxidation and past habitability while navigating mechanical wear.
NASA's Curiosity rover captured a stunning panoramic view from Mount Sharp on Mars, highlighting ancient water-related geological features and continuing its scientific mission after over a decade on the planet.
NASA's Curiosity rover accidentally discovered pure sulfur crystals in a Martian rock, challenging previous understanding of Mars' geological history and suggesting complex environmental conditions, with future investigations planned in a region with underground mineral formations.
NASA's Curiosity rover created a panoramic 'postcard' of Mars by combining images taken at different times of day, revealing the planet's geological features and its watery past, with artistic color enhancements to highlight the scene.
NASA's James Webb Space Telescope and Curiosity rover have been inducted into TIME's 'Best Inventions Hall of Fame' for their groundbreaking contributions to space exploration and understanding the universe, highlighting their global impact over the past 25 years.
NASA's Curiosity rover has made significant progress in Mars exploration, including creating a detailed 360-degree panorama of the Nevado Sajama site, analyzing organic compounds in drilled samples, and returning to nighttime imaging of drill holes, all while preparing for future investigations before the holiday break.
