The reality is that no one in this thread or anyone else knows how much water is there.
The instuments used could only penetrate a very thin layer of the surface so that is the only place we know for sure it exists. The water could go
much deeper than just a thin layer but the instruments can't see into the regolith to confirm or deny this.
We've hit the moon with some very large impactors over the years and we've never seen large amounts of water from those impacts.
Further more the solar wind theorey is just that... a theorey not a fact. In the press conferance they said that it is possible that the water is
seeping up from under the surface. In other words there could be resivouirs of water underground for all we know.
Could be, but there are reasons why that is less likely, including previous impact evidence and a failure to detect such in seismic studies. I'll
believe the seepage theory when there is evidence for it.
Interesting how some are so quick to say there is very little water.
There's no real reason to think otherwise (and some reasons to think there isn't), at least at mid-latitudes. The poles are a different story.
I'll believe the "large amounts" theory when there is proof.
