Quick Summary
NASA’s Curiosity rover is investigating strange spiderweb-like ridges on Mars that may reveal a hidden chapter of the planet’s watery history. These “boxwork” formations likely formed when groundwater flowed through cracks in the rock, leaving minerals that hardened into ridges while surrounding material eroded away. New chemical analyses of drilled rock samples show minerals linked to water activity.
