NASA’s Curiosity rover has stumbled on the largest patch of polygon-shaped ground fractures it has ever seen on Mars, a discovery that could reveal more about the planet’s watery past. A 360-degree panorama captured June on 19 and 20, 2026 shows honeycomb-like polygons stretching to the horizon in every direction. Curiosity has photographed small clusters of these geometric shapes before, but nothing on this scale. “We measured their shapes and chemistry carefully and are hopeful there are clues in the data as to how these features formed.” “The rover has previously uncovered chemistry left over from Mars’ watery history, including carbon-based molecules believed to be precursors to RNA and DNA, two nucleic acids that carry genetic information.”
