Bombing the Moon for Water

s20451 writes "In 1998, NASA scientists deliberately crashed the Lunar Prospector into the Moon, in a failed attempt to detect traces of water allegedly hiding in deep craters at the lunar south pole. Now the BBC is reporting a new proposal to attack the lunar poles with "Bunker Buster" missiles to liberate a detectable amount of water. Called Polar Night, the mission is being proposed as part of the "Discovery" series of probes."

    Life?

    More like fuel. Hydrogen and Oxygen. Guess what the shuttle engines run off of?

    If we discovered water in any signifigant quantity on the moon, it would (someday) make getting there and back much cheaper and easier. Instead of packing the gas with us, we can stop at the ol' lunar gas station. It is so hellaciously expensive to put things in orbit, every pound saved is a penny earned.

    It could also make construction of spacecraft on the moon or in orbit a possibility. Again, the less we have to bring up with us, the better.

    Did anyone actually read the friggin article? They don't want to bomb the moon. The bombs will not be filled with explosives. They will be filled with scientific equipment to detect water. They're just going to drop them into crevices.

    Moon does'nt have oxygen. Therefore this bomb will need to have its own oxygen system.

    Umm, the vast majority of conventional munitions have their own oxidizing agent, with very few exceptions( such as the fuel-air bomb ).

    If a substance's oxidation rate is dependent on its contact with atmospheric oxygen, it would be far more likely to "burn" than "explode".

    The dust(?) created from this bomb will linger far longer than earth because of moon's gravity.

    Another problem with your reasoning. The specific reason that dust "lingers" on earth is buoyant forces BY THE AIR upon very small dust particles. the moon's gravity well is smaller than that of the Earth, but the fact that F=ma will prevail without impedance by an atmosphere will make the "dust" settle rather quickly.

    Most would be able to go off in a vacuum. There's what, about 250 grams of O2 in a cubic meter of air? That's not enough for solid explosives to use.

    What I think the parent was saying, though, is the MOAB would explode, but there wouldn't be any way for the shock wave to propagate. It would just be a spray of high-velocity chemical by-products of the explosion. For a MOAB, though, that would still be nasty. I wouldn't want to be 10 meters away from that in a spacesuit, but you could be a LOT closer than with a similar explosion in an atmosphere.

Hashem August 12, 2001 Heat of Formation The general formula for explosives is CxHyNwOz. Explosive reactions are oxidation reactions. More generally, the oxidizer does not have to be oxygen; it can be an oxidizing salt such as Nitrate or Perchlorate.

    Taken from the King James Version, so you can't even play the "modern devil-inspired translations" card: references to the moon in the KJV.
