My apologies I didn’t realize you were answering a post I made to raiderboy.
At any rate the darkside of the moon has been collecting comets and comet fragments since it started spinning around the Earth the permanent shadow on the darkside means those fragments are preserved, is there enough to mine I don’t know, but when you consider the condition of the moon cosmic collisions are a given.
Next to war of all spending the the Government does only the original space program return more in the way of advancement and knowledge in multiple fields. When done properly there are lots of returns.
I sleep better knowing the Stars and Stripe fly on the moon rather than the red star.

Actually, the comets all came from Earth, when the crust of the earth was ruptured during the Genesis 6 judgment.
That is why they orbit the Earth and the sun predictibly. (see Kepler)

Do you remember how they used to tell us that there would be 50 or 60 feet of dust on the surface of the moon?
When they landed they could not find enough dust to fill a bag!
No strong reason to believe that the other side would be different in that respect.
