NASA's LCROSS Mission Proves Lunar Ice Suspicions 177

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.'"

          Yes, because that's *so* much cheaper than just building them in orbit. Yes, let's ferry all those materials hundreds of thousands of miles to the moon and then sink them in another gravity well... that'll be *so* much better.

          • Supposedly it would be - or thats what people on /. have said before (though thats hardly a reliable source). Because the Moon's Gravity is so much lower than Earth's, it'd be SO much cheaper to launch a LONG RANGE shuttle from there (say, one past mars), that the cost of sending a simple cargo run to the moon is less than the amount you'd save.

          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.

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

        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.

      The only reason I buy bottled water these days is that it's already conveniently packaged. I go to the gym sometimes (ok, I admit I went every day for the first month after I signed up and more recently ha

    Or, maybe it did hold water... until the impact.

  • When they say ice and water, are they talking about the stuff you can fill up your canteen and go, or is there something else in it that would make it undrinkable?

    I ask because Mars has its ice caps, but as I understand it's just dry-ice (frozen CO2) that would make for an awesome Halloween party effect, but obviously won't sustain any sort of life.

      Plenty. Probably, heavy metals and other inorganic contaminants.

      But it should be easy to filter them. Even if you have to break down water to hydrogen and oxygen, it'll still be cheaper than hauling water all the way from the Earth.

      They have found water, as in H2O, not CO2.

      It may or may not be mixed with anything narsty (I'd lean toward "almost certainly does"), and it may or may not exist in sufficient quantities to be useful.

      However, this is still a potentially significant discovery. If a future expedition discovers that there's enough water up there, it could make lunar bases easier to build. After all, water is probably the single heaviest thing you'd have to carry up for a lunar base. If a ready supply is already there, that's a big start, even if you have to develop some technologies to scrub the nasties out of it before you can drink it. It's also an important building component if you want to use local materials to, say, build protective walls over your delicate settlement. Lunar adobe brick made of local dirt and local water, for example. Then you wouldn't care what contaminants are in it, as long as it could be used to solidify bricks.

        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.

        • Good point.

          I'm not so sure about the "fire" bit, since burning Hydrogen for fuel requires recombination with Oxygen, so you're back to square one with less energy than you started with in solar energy to start with...

          But it is efficient storage, so you could H2 and O2 tanks to fuel your vehicles, for example, and only have to have one mother of a huge solar array to collect the energy necessary to make it...

          • by jhfry ( 829244 )

            Actually thats exactly what I was thinking... sure you need to supply O to the equation to burn the H... but thats exactly what they do in rockets to get things into space in the first place.

            If they can use solar energy on the moon to create liquid H and O to refuel spacecraft it could provide a much needed boost into the outer solar system. Using solar energy directly doesn't yet give a lot of thrust (as far as I understand it) so it can take a long time for a spacecraft to accelerate.

          Oxygen is cheap on the moon if you can get a good energy source (ie. nuclear reactor). The moon is mostly silicon / iron / calcium oxide.

    • They don't mean dry ice, obviously because they are talking about water.

    • It'd require a bit of work before being drinkable, but as other posters have pointed out, water is a specific compound. If they'd said ICE then that is very ambiguous, but the word "water" is quite specific.

      The water may just be stored in rock hydrates. In that case, you wouldn't even be able to tell that it's there, it would look just like rocks.

    I've no background and little education in this area but I do have an off the wall question. I have some understanding of the theory describing the initial impact from which the moon is thought to have come, and, the attendant theory that the formation of the moon may have been one of the first, big contingent happenings that drove the development of life on earth. My question centres on the material that made up the body that smashed into the early earth, added much to the earth's "girth" and gave us the present moon. Is it possible the impacting body was composed of a lot of water? There's questions surrounding how earth came to have so much water. If the impacting body that gave us the moon contained a great amount of water, the impact, formation of the moon, water on earth and the early evolution of life comes into focus as a "just so" story.

    just my loose change

     

    • by smoker2 ( 750216 )
      The moons creation may have added some more elements to the mix, but as oxygen is the 3rd most plentiful gas in the universe (after hydrogen and helium), there's pretty likely to be lots of water everywhere. Having an atmosphere and a magnetic field make it easier for it to stick around in puddles on earth.

        I'm a deeply confirmed atheist, so much so that I can't imagine trolls at all, other than as pejorative labels for creationists. This linked article [nasa.gov] was the first handy bit I could find that speaks directly to my post. /. has run a few stories about the problems with the earth's amount of water and it's origins.

    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!

    Check out the paper here: http://xxx.lanl.gov/abs/0909.3832 [lanl.gov]

    • Interesting paper. After seeing page 39 I now have an image of moon farts locked in my mind. "Transient
      Lunar Phenomena" indeed.

      It seems like they are saying 'find the largest sources of outgassing and you will find the highest concentrations of water' (at the poles), caused by vapor phase changing to subsurface ice.

    Radium?
