NASA好奇号火星车在火星Valle Grande山谷发现了大规模的蜂窝状多边形裂纹地貌1。这些多边形每个宽度仅1.5至3英寸（4至8厘米），覆盖了整个可见区域1。项目科学家Ashwin Vasavada表示："我们通过好奇号的视角看到过许多迷人的地形，但这片多边形海洋让我们叹为观止"1。
好奇号自2012年8月5日登陆火星以来已运行14年1。全景图拍摄于第4,930和4,931个火星日（2026年6月19-20日）1。科学家正在研究这些图案的成因，可能的解释包括干燥泥土裂纹、温度变化和压力等因素1。
根据已有数据，火星古代曾存在湖泊和溪流，好奇号还发现了包括RNA和DNA前驱体在内的有机分子1。
NASA's Curiosity rover has identified an extensive field of polygonal honeycomb-patterned surface cracks in the Valle Grande valley on Mars.1 The distinctive formations, each measuring between 1.5 and 3 inches (4 to 8 centimeters) wide, blanket the visible terrain across the region.1 Images of the landscape were captured on Mars days 4,930 and 4,931, corresponding to June 19-20, 2026.1 According to Ashwin Vasavada, the mission's project scientist, "We've seen a lot of fascinating landscapes through Curiosity's eyes, but this sea of polygons took our breath away."1
Scientists are investigating the origins of these geometric patterns, with possibilities including dried mud cracks, temperature fluctuations, and subsurface pressure variations.1 The discovery marks a significant finding for Curiosity, which has been conducting research on Mars for fourteen years since its landing on August 5, 2012.1 The rover's exploration has previously revealed evidence of ancient lakes and streams on Mars, as well as organic molecules including RNA and DNA precursors.1
