Dreams of establishing a manned Moon base could become reality within two decades after India’s first lunar mission found evidence of large quantities of water on its surface.
Data from Chandrayaan-1 also suggests that water is still being formed on the Moon. Scientists said the breakthrough — to be announced by Nasa at a press conference today — would change the face of lunar exploration.

There is no lake. There is a small amount of water material (which may not even be water) widely spread over the surface. If it is water, it is most likely in the form of ice.
[edit on 9/24/2009 by Phage]
The amount of water in any one place is tiny. Clark estimated it at about a quart per ton of soil.
The moon "is almost as wet as a bone," Lucey said in an e-mail interview with The Times. "It is in the form of an imperceptible film on soil grains, perhaps several molecules thick."

Sounds familiar.

No Armap wasn't for your post. I guess we did respond at the same time. Was for this one:

The instruments used to detect the water could only penatrate a thin layer of regolith so that is why they talk of it that way. There could be larger amounts of water further down. So to say it is only a thin layer as though it was a fact is just as much of a distortion as anything Phage could accuse Zorgon of.
They can't see deeper into the regolith than a thin layer so this is what they will talk about.
And before you say there is no evidence for more water underneath this thin layer I will add this... Higher concentrations of water were found in the craters. To me this suggest that there may indeed be more water found beneath this thin layer that the probe was not able to analize.

Nobody is talking about a lake. Since when a large amount of water means lake? Never mentioned lake in my post.
Q: That translates to what in volume?
A: We were very conservative in the press release, but if you take basically 100 square kilometers by roughly 50 feet, you get a volume of something like a quarter of a cubic mile, I think it's on that order. It's a considerable amount, but it's not a huge glacier or anything like that.
Q: Can you compare that with something you know?
A: It's a lake. A small lake.
Q: But it's a dirt lake.
A: Right, mixed in. (Laughter) A dirty lake.
Idid In the Department of Defense document I linked to THEY say a lake a small lake... 100sq kilometers 50 feet deep FROZEN with dirt in it
Pretty much what we heard about today. It's wouldn't be surprising if the concentrations in shadowed craters is greater but that's what LCROSS will tell us.
A: You would probably see... First of all you wouldn't see anything because you'd be in the dark. But if you had a flashlight and you illuminated the surface, you would see a surface that looked not unlike any place else on the moon, but if you were to dig down into that and pull it up, you would find that there would be ice crystals contained in the interstices between the dust grains. So it's not a sheet or a pond. It's not an ice rink on the moon. It's basically ice mixed into the dirt.

Actually, you have it backwards. What was actually said was that it's dirt with some ice mixed into it.
