NASA announced today that data from the LCROSS lunar probe launched in June has revealed a potentially significant amount of water under the moon's surface. Scientists have long wondered about the possibility of water lurking somewhere on the moon, and now, at long last, they have their answer.
The implications of this discovery are far-reaching; the domain of science fiction may be about to get a lot smaller. Self-sustaining colonies on the moon could be in the not-too-distant future. With a plentiful supply of water, moonies (I've decided that we'll call them that) could live unassisted from earth for a while. Such colonies could be the location for a super-powerful telescope or a low-gravity launch pad for spacecraft to delve deeper into space.
Beyond that, though, is the possibility of life on other planets. If water can exist on the moon, it could exist elsewhere, too. If it does, lifeforms of endless variety could potentially thrive and evolve.
The possibilities are endless.
