NASA's LCROSS Mission Proves Lunar Ice Suspicions

NASA is reporting that preliminary data from the LCROSS mission indicates that there really is water in one of the permanently shadowed lunar craters, just as they suspected back in September. "'We are ecstatic,' said Anthony Colaprete, LCROSS project scientist and principal investigator at NASA's Ames Research Center in Moffett Field, Calif. 'Multiple lines of evidence show water was present in both the high angle vapor plume and the ejecta curtain created by the LCROSS Centaur impact. The concentration and distribution of water and other substances requires further analysis, but it is safe to say Cabeus holds water.'"

Whats the hold up

Base on the moon! Lets go fuckers!

There's nothing worth "getting" at the Lagrange points, or geosynchronous orbit, or any number of places. That doesn't mean it's not worth going there.

We all know that the reason to have a moon base is to build a libertarian utopia.

Some actual serious reasons:
1. We'd get off this rock for more than a quick visit. If you're looking at major achievements of humanity, I'd think that would definitely rank somewhere significant.
2. Because we'd be off this rock, we'd have a good environment to test handling that sort of thing from an engineering standpoint, with the possibility of a much more manageable return if something were to go wrong. Important questions like "how do we handle the issue of solar radiation", "Can we grow enough plants in controlled environments to sustain an off-Earth colony", and so forth.
3. Heck, I'd pay good money to walk on the moon.

In short, this sort of thing isn't about making cash, it's about taking yet another small step for mankind. Yes, that requires looking past your lifetime, but that doesn't mean it's not worth doing.

Water is good news. I'm sure there's going to be lots of water reclamation equipment for any base we do end up building, but having external sources of water is a definite plus.

That was a pretty ignorant post on He3 mining due to the exaggerated cost estimate, lack of local manufacture, and ignorance of other materials found in lunar regolith.

Given that the moon is composed of largely the same minerals as those on earth, you'd have to massively deplete our terrestrial resources before mining the moon became even *remotely* cost effective.

Even if it does require half a million tons of equipment, that equipment can be made on the Moon rather than launched from Earth at $40k or even $4k per ton.

Uh... from what, exactly? Or do you plan to bootstrap and entire manufacturing sector on the moon and *then* start mining He3?

If you can get the overall fusion power infrastructure including lunar mining to under say, a couple of trillion dollars, then you could switch over the US electricity and heating infrastructure completely to lunar-fueled fusion power. My view is that this mining infrastructure could probably be made and deployed for hundreds of billions of dollars *or less* once manufacture is established on the Moon.

Wait wait... let me get this straight. *If* you can build a fusion power infrastructure *and* lunar mining, including an *entire manufacturing base on the moon*, for under a *couple of trillion dollars*, a moonbase is suddenly worthwhile?

Wow. That's a really convincing argument, there. ::rollseyes::

Or we could just get Hydrogen-Boron fusion working, which runs at lower temperatures, and uses materials easily available on earth.

But you're right. I'm sure your idea is much better.

All of these would be byproducts of such a vast mining operation. Revenue from this operation would be more than just He3.

None of which is worth the cost of retrieval. All are exceedingly common, save for helium, which, conveniently, is a by-product of H-H fusion, and so if we ever did manage to develop controlled fusion, we could just make it ourselves.

Mining

Finally! Something we can mine the Moon for. This will spur space competition to get this valuable resource. I can't wait for my first sip of $10000 Evian Moon Mineral Water.

There's water on the Moon
We found it with big boom
For the probe crashed down
Impacted the ground
There's water in the plume!

Model Predicts Lots More Water

[GreenPhreak]

The dominant paradigm since the Apollo Missions was that the Moon was as dry as a bone.

However, a paper was put out recently (before the discovery of water a month ago) proposing a model for water and other volatiles venting out of the interior of the Moon. One of the predictions of this model is that there should be significant subsurface water primarily near the poles. The results from Chandrayaan-1 and LCROSS today confirms that this is true--there is significant subsurface water near the poles. The claims that the water is solely on the surface and due to cometary deposition or solar wind interactions are now blown "out of the water".

This model predicts a lot more water under the surface for potential use in human exploration. w00t!

Re:Can we just clarify something?

[jhfry]

Better yet... H2O has a great O element... and you can breathe it!

So, suppose you could drill down and hit a well of ice. A bit of solar energy pumped into that frozen mass yields liquid water, a bit more gives hydrogen and oxygen. Now you have fuel (fire) and air and water. Earth will be the tough element to obtain. I don't imagine that moon soil is all that good for planting, and most plants need nitrogen that may not be easy to come by on the moon.

Either way... water far more valuable when you realize that its not just water but O and H too.

cue the aliens on the Moon, landing there and using the water to mix with the scotch and other lame ass jokes.

The aliens have set themselves up with a nice little night-club on the moon...

...no atmosphere, though.
