NASA's Perseverance rover has identified carbonate minerals across the Jezero Crater on Mars. These minerals suggest that liquid water once reacted with carbon dioxide to trap carbon in rock formations, a natural process similar to mineral carbonation used in terrestrial carbon capture technology. Researchers believe this widespread carbon storage may have played a critical role in cooling the Martian climate over billions of years. The findings provide a geological case study in how planetary atmospheres can be altered through the chemical trapping of greenhouse gases in the crust.
