Why did NASA fire a projectile into the moon?

Live video feed of NASA's LCrosss-Centaur Lunar Impact mission to study the possibility of water in the lunar southern polar region.
They are firing a rail at a crater at twice the speed of a bullet and examining the contents of the impact debris.





Details of the mission

The impact plume will be visible from the Western US through small telescopes.

Wonder if I will be able to see it with my little scope? It's going to be very cold here tonight!

Not much to see on the BBC relay, the controllers seemed most concerned with getting their jargon right !

I'm glad I stayed in bed. Apparently there was not much to see.

Of course the reason this was done is to investigate the possibility that there may be water on the moon that may be used by a colonizing group. The answer might be a determining factor in the feasibility of deploying such a colony. If there is water, it is orders of magnitude more feasible that such an undertaking might be possible.

<<Why did NASA fire a projectile into the moon?>>

Maybe they intend to accidentally fire some other bombs on the sites of Moon landings, to hide the prove of the non-landings?  ;D
...joking of course...

yes, it is very expensive to take water to the moon.

"How Valuable Is This Water?

NASA is calculating the economic value of the lunar water as a resource for human exploration of the Moon. For instance, the space agency has estimated the cost of transporting the same volume of water from Earth to orbit. Today, it costs about $10,000 to put one pound of material into orbit, but NASA is working to reduce that to only $1,000 per pound. It would cost $60 trillion to transport 33 million tons of water to space, plus an unknown additional cost to transport it to the Moon's surface.

From another perspective, a typical person on Earth consumes an estimated 100 gallons of water per day for drinking, food preparation, bathing and washing. At that rate, 33 million tons of water -- which is 7.2 billion gallons of water -- could support a community of 1,000 two-person households for well over a century on the lunar surface, without recycling. Of course, a cheap way to mine the water crystals from the lunar soil would have to be developed for the water to become a useful resource for drinking or rocket fuel to support human explorers."

I think it is to influence the committee that is discussing funding for NASA .

" Why did NASA fire a projectile into the moon "
Well we need to know how to defend ourselves, right.

I wouldn't want the moon as my nearest neighbor, and certainly not marrying my sister. And now you're gonna say I'm an racist right..

Well, ask yourself. Would you let your sister marry it?
