NASA's Curiosity rover images a field of small polygons in Gale Crater, about 4–8 cm across, likely mud cracks from ancient wet–dry cycles; these ground-level features differ from the much larger polygons seen by orbiters, and scientists caution that their exact formation is still uncertain, with possible links to early Martian climate during the Noachian–Hesperian transition.
A resurfaced Curiosity image from Gale Crater shows a dark, tripod-like object that some viewers dub a 'jellyfish' and even a UFO, though many think it's likely a photographic glitch or lighting artifact; NASA hasn't issued a formal statement and Curiosity has been exploring Gale Crater since 2012.
Epictetus argues that you cannot learn something you already think you know, warning that certainty can block real understanding. The piece links this to the Dunning-Kruger effect and to a Yale study showing how internet searching can inflate perceived knowledge by conflating accessible information with personal knowledge. It advocates a practical, beginner’s approach: explain the concept aloud or in writing without looking up the answer, and maintain curiosity to keep the door open to genuine learning, treating certainty as a cue to reassess rather than a badge of mastery.
Curiosity stamps the letters JPL in Morse code on Martian terrain with its six aluminum wheels. Those repeating marks serve as a built‑in visual odometry reference, helping NASA's navigation software compare commanded wheel rotations with actual movement across difficult ground to detect wheel slip. The feature is an engineering convenience, not a sensor, designed to provide landmarks and scale while respecting the rover's mass and design limits.
NASA's Curiosity rover captured a 360-degree panorama of honeycomb-like polygonal textures across Valle Grande on Mars, with patterns wrapping around the Miraflores butte. Scientists say these polygons likely formed from mud cracks, cycles of warming and cooling, or sediment compression, offering clues about Mars' ancient water activity and its potential to have supported life.
NASA's Curiosity rover has spotted a vast field of tiny polygonal fractures in Valle Grande on Mars, forming a honeycomb-like landscape that climbs a nearby 20-foot-but-tee. The 4–8 cm polygons may result from drying mud, thermal cycling, or compression, and scientists will study the data to determine the exact formation process. The find adds to evidence that ancient Mars hosted water and chemistry capable of supporting life.
NASA’s Curiosity rover captured a 360-degree panorama of Valle Grande revealing a vast sea of polygonal fractures across the Martian landscape, including around the 20-foot Miraflores butte. Scientists are studying how these honeycomb patterns formed and what they imply about ancient water, chemistry, and Mars’s potential to have supported microbial life.
NASA’s Curiosity rover has found a vast field of honeycomb-like polygons on the Martian surface near Valle Grande, with polygons about 1.3 to 3 inches across. Scientists don’t yet know how they formed and are analyzing the data; similar polygonal patterns have appeared before as mud cracks from ancient wet-dry cycles, but the sheer abundance in this location is puzzling and could offer clues about Mars’ past climate and habitability.
NASA's Curiosity Mars rover reveals wheel wear—holes and cracks—from nearly 14 years and about 32 km of driving, in a MAHLI image taken on Sol 4963 (July 23, 2026). NASA/JPL notes the wheels are holding up well despite rough Martian terrain as Curiosity continues to explore Gale Crater, having logged over 20 miles of travel in its long-running mission.
NASA's Curiosity rover spotted hexagonal honeycomb-like textures on the Martian surface in Gale Crater, seen up close after an orbital view; with nearby dark rocks and no clear explanation, scientists are weighing ideas from erosion patterns to meteorite fragments and plan further investigations.
In a 3.5-billion-year-old clay-rich rock from Gale Crater, Curiosity detected 21 carbon-based molecules, including a nitrogen-containing ring linked to prebiotic chemistry, demonstrating ancient Martian sediments can preserve complex organics for billions of years. Using the SAM instrument with a TMAH wet-chemistry method, seven molecules were confirmed as new detections on Mars, suggesting these organics may be fragments from larger material and highlighting preservation as a key story for future missions.
Two NASA rovers, Curiosity and Perseverance, run on a Martian day of 24 hours 39 minutes, so JPL staff spend about 90 sols living on Mars time, shifting their wake/sleep cycles and meals to align with Martian sunrise. Because of the signal delay, commands are scripted for the next sol rather than realtime control, and coping measures like blue-light lighting, blackout curtains, and timed caffeine help manage sleep loss and social dislocation. After the commissioning phase, teams gradually revert to Earth time, aided by increased rover autonomy (Mars Global Localization) that reduces the need for humans to chase Martian dawn.
NASA’s Curiosity rover freed a 1.5‑foot rock that froze onto its drill on Mount Sharp after several days of remote recovery work. The rock, nicknamed Atacama, finally detached on May 1 following vibration-based maneuvers, and Mastcam imagery shows the drill hole left behind while mission controllers confirm the rover remains healthy and continues to explore for clues about ancient Mars water.
NASA’s Curiosity rover encountered an unusual hitch when a rock named Atacama stuck to its drill sleeve during a Mars sampling attempt, but ground teams freed it after several maneuvers; in Greenland’s Inglefield Bredning, researchers deployed a deep-water camera and hydrophone at 260 meters to document 478 organisms and sounds (including narwhals and iceberg activity), showing a feasible approach for Arctic seafloor studies; NASA also released thousands of Artemis II mission photos featuring lunar, Earth, and Milky Way views.
NASA’s Curiosity rover, after six years on Mars, reveals in a new time-lapse how its wheels and the Martian surface have endured. Captured from 2020–2026, the footage shows wheel wear from rocky terrain and dust moved by wind and seasons, helping scientists distinguish wheel-imprinted material from wind-blown dust and study atmospheric changes. Despite punctures and tears, Curiosity remains mobile, having driven about 32 kilometers, and its observations have influenced the design of the Perseverance rover.
