Curiosity Finds Honeycomb-Patterned Polygons in Martian Soil

TL;DR
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.
