Billions of years before human eyes turned skyward to wonder at Mars, the red planet may have known seasons — wet and dry, filling and receding — much as Earth does still. NASA's Curiosity rover, climbing the layered slopes of Mount Sharp in Gale Crater, discovered hexagonal mud crack patterns at a site called Pontours in 2021, geometric signatures pressed into ancient stone that speak of repeated cycles of water and drought. Scientists believe these cycles are not merely atmospheric curiosities but may be among the very conditions that allow life's chemistry to begin. In finding them on Mars,
