Summary:
- NASA's Curiosity rover has found evidence that Mars may have had more carbonate minerals in its past than previously thought. Carbonates are important for understanding the planet's climate history and potential for supporting life.
- The rover detected carbonate minerals in rock samples, indicating that Mars may have had a more Earth-like atmosphere in the past that could have supported the formation of these minerals.
- This discovery helps scientists better understand the evolution of Mars' atmosphere and climate, and provides clues about the potential for past habitability on the planet.
