"Significant" water found on Moon

The Mars thing is- it HAD volcanos which is a sign of a molten core- which is what creates our electro-magnetic atmosphere.
Thus we are protected from solar bad-guys by lava.

Mars was potentially much like Earth at one point. Producing green house gases is one of the most plausible ways to thicken the atmosphere (which would release more gases from martian rocks), increase the temperature, and allow liquid water to form.

Anyways. The moon...Yeah.
