NASA's Curiosity rover has spotted a vast field of polygonal, hexagon-like fractures on Mars; while striking, researchers caution that these features could form through multiple processes (mud cracks, freeze-thaw, or regolith dynamics) and not a single cause, offering clues about Mars' geologic past while the rover's wheels continue to endure as it explores Valle Grande.
NASA's Curiosity rover spotted a vast field of honeycomb-like polygonal fractures in Martian soil at Valle Grande, observed June 19–20, 2026. Each polygon measures about 1.5–3 inches (4–8 cm) across, and scientists are still unsure how these features formed, though temperature-driven water movement through sediment layers is a leading hypothesis; researchers are continuing to analyze the data for clues.
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 spotted a vast field of honeycomb-like polygonal fractures in Valle Grande, Mars, prompting researchers to explore whether mud drying, thermal cycling, or sediment compression formed the patterns and what they reveal about the planet’s ancient climate and history of liquid water.
NASA's Curiosity rover has spotted the largest field of honeycomb-like polygonal cracks on Mars in the Valle Grande valley, with polygons about 1.5 to 3 inches across. Scientists believe they formed billions of years ago through repeated wet and dry cycles, adding evidence that ancient Mars possessed water and the chemistry needed to support microbial life; the mission has also surfaced sulfur crystals and other unusual rocks along the way.
NASA’s Curiosity Mars rover captured a 360‑degree panorama of a vast honeycomb‑textured field in Valle Grande—the largest patch of polygonal fractures NASA has found on Mars—each polygon about 1.5 to 3 inches wide. Scientists are analyzing their shapes and chemistry to understand how they formed and what they reveal about Mars’ watery past, with the texture spanning outward in all directions in a panorama captured on sols 4,930–4,931.
NASA’s Curiosity rover stitched 340 images into a 360-degree panorama of Valle Grande on Mount Sharp’s foothills, revealing a vast sea of honeycomb-like polygonal fractures across the Martian plain—evidence of ancient water activity and a clue to Mars’s past habitability.
