‘Moon water not like groundwater’

Hey, at least it’s there, improving prospects for long-term moon colonies. (Reuters) What’s different about water on the moon? Yes, it’s all frozen, smart ass. But it’s also “bound up with minerals such that it is stable in the airless and low-gravity environment of the moon.”

How do future Moon people get at the stuff? It’s a challenge. You’d need to harvest a patch of lunar soil the size of a baseball field to yield one glass of water. (New Scientist) One idea is heating the soil, then collecting water vapor, but wow, that seems like a lot of work.
