During its mission on Mars, NASA's Curiosity rover photographed a vast field of polygonal fractures resembling honeycomb textures, each spanning 4 to 8 centimeters. This discovery in Valle Grande represented a larger scale of such features than previously observed and stretched to the horizon, including around a 6-meter high butte.
Polygons on Mars can form through various mechanisms such as mud cracks or thermal cycles causing expansion and contraction. Curiosity’s long-term exploration also uncovered other significant evidence of a former Mars environment capable of supporting microbial life, including lakes, streams, and sulfur deposits.
