Data from NASA's Perseverance rover reveals significant deposits of carbonate rocks in the Jezero Crater on Mars. These minerals suggest that carbon dioxide was pulled from the ancient atmosphere and stored in the planet's crust, a process similar to natural carbon sequestration on Earth. Researchers estimate that these rocks could hold trillions of kilograms of carbon. This widespread sequestration likely played a major role in cooling the Martian atmosphere billions of years ago, providing new insights into the planet's climatic evolution and potential for past life.
