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.
China's Zhurong rover has discovered mysterious polygons beneath Mars' surface, similar to those spotted by NASA in 2012, suggesting a long, wet period in the planet's ancient past. These features, found 35 kilometers below the surface, could indicate the presence of water and increase the likelihood of past life on Mars. The polygons, potentially formed between 3.7 and 2.9 billion years ago, may have resulted from water-related processes, such as freeze-thaw cycles. While the rover has been decommissioned, researchers believe the Utopia Planitia region remains a prime location to investigate ancient water activity on Mars.
