"The newly released study has found that water was most likely formed on the surface of the Moon by the constant stream of charged particles ejected from the Sun. The finding “represents an unanticipated, abundant reservoir” of water on the moon, according to researchers from three U.S. universities, who formally reported their results Sunday in the journal Nature Geoscience."

I remember this. Robert Heinlein wrote about this 60 or 70 years ago in "The Moon is a Harsh Mistress." In his novel, Luna has been colonised and Terra is the colonial overlord exploiting the mining products of the Loonies. The big rocks mined are filled with lithium and other rare earths. They are shot back to planet earth with a mass driver (someone will explain). The rocks land in the Pacific Ocean somewhere where they are retrieved, for...?
The inevitable revolt takes place on the moon and freedom rings forth through the maze of tunnels that these people live in. The best part of the book was the obsessive, inevitable meditation by Heinlein on the various forms of marriage among the Loonies. As a teenager this certainly seemed the most interesting part to me. The most exotic of these forms was the "line marriage." Look it up.
So now it is known that there is a lot of water of the moon. The sky is the limit. pl
