NASA just spotted what could be a brand-new mineral on Mars, and it might have formed less than 3 billion years ago! Scientists found unique iron sulfates in two regions, hinting that Mars was more active—and maybe even habitable—way more recently than we thought. The mineral’s weird crystal structure and thermal stability have everyone buzzing. If it’s confirmed, this could totally change what we know about Mars’ history and its chances for life! #Science #NASA #MarsDiscovery
