A field of polygons as seen by the NASA Mars Curiosity rover. Aka honeycomb textures and polygonal fractures, each one is about 4 to 8 cm across. "A variety of processes can contribute to the honeycomb textures, including repeated, perhaps seasonal, wet-dry conditions, cycles of warm and cold temperatures or compression that squeezed water out of the sediment when the surface was buried" https://www.nasa.gov/missions/mars-science-laboratory/curiosity-rover/nasas-curiosity-mars-rover-discovers-field-of-honeycomb-textures/ #Science 1/n
