Did Mars once have a massive ocean? New study suggests ancient ocean in Martian clay mounds

Discoveries of clay minerals in Martian mounds by researchers indicate that Mars once had large bodies of water billions of years ago. This finding, exhibiting a radically different climate during Mars' Noachian era, boosts chances of ancient life and lays the groundwork for the future Rosalind Franklin rover mission exploring potential life signs.
