Recent work using non-destructive neutron imaging and updated climate simulations offers complementary evidence about Mars' watery past: scans of the celebrated NWA 7034 “Black Beauty” meteorite reveal substantially more ancient water than previously thought, while a newly adapted climate model shows how thin, seasonal ice could have insulated liquid water beneath for decades.
New scans and models shed light on Mars' hidden water
Advanced neutron imaging of a Martian meteorite and a fresh climate model both point to ways water could have persisted on ancient Mars.
