I hope to post more later but the LCROSS team did have a program on NASA TV today it was a press conference and I watched most of it. I have been looking for it and stumbled on to it in the middle.
The basic data is that there is both ice and water saturated material on the poles of the Moon. In the spot which the impactor struck there was certainly more water present by proportion than there is in the Earth’s driest deserts.
To review my earlier posts see the following:
It is important to understand that a ew doaen gallons of water in the ejecta cloud is so very much more than no water at all. On the other hand it is so much less than a real ice cap. But it is possible to imagine exploiting it for a base.
