Interesting!
If there’s ice in there, there’s probably a lot.
That ice can be used by humans. Drinking, irrigation, and fuel, by breaking the hydrogen from the oxygen, and, of course, the oxygen gives air to breath. There’s nitrogen mixed into the lunar soil so they should be able to recreate a nice atmosphere.
Woah!
I meant in their habitats, domed cities or underground tunnels, not the entire surface of the Moon.
