Did Mars used to be a tropical paradise? Scientists just found bleached rocks in Jezero Crater that could mean Mars was once warm, wet, and maybe even had rain for millions of years. The wild part? These rocks are made of kaolinite, which forms on Earth after ages of rainfall. If Mars really had that kind of climate, it could’ve been a perfect spot for life to thrive. Mind. Blown. #Science #MarsDiscovery #SpaceNews
