I found a newspaper account of 'moon water' from last Friday, but NASA sites do not seem to be updated yet. Most info was attributed to Alan Binder, but the news on his website is from last January. 'Clementine' did not make a direct detection of water, and the newer 'Lunar Prospector' still won't make a direct detection. They're looking for hydrogen, and assuming it's in water. The latest 'Lunar Prospector' report on the NASA/Ames website doesn't say anything about water.

I'd take some ordinary water along just in case. That moon stuff is supposed to be at -280 F, and you'd break your teeth trying to bite that stuff, or use up all your fuel trying to melt enough for a drink. The stuff's supposedly at the poles, so solar power converters aren't going to be very effective. [cosine term for projected area, is going to nearly kill that. Normal solar radiation will probably be the same as that on earth, about 1355 watts/sq. meter, but at 89 degrees incidence angle, efficiency is less than 2%]
