Curiosity Rover Finds Evidence of Ancient, Ice-Free Lake on Mars

NASA's Curiosity rover has uncovered compelling evidence of a shallow lake on Mars billions of years ago. Analysis of ripple marks in Martian rocks within Gale Crater indicates a lake less than two meters deep, with its surface exposed to the atmosphere. This suggests a warmer climate and liquid water on Mars at the time, challenging some hypotheses about the planet's early history. The discovery provides crucial insights into Mars' ancient climate.
