From a scientific point of view, we now know that the water is interlaced with the lunar soil in many locations, perhaps as remnants of comet collisions with the lunar surface.
Supplying fuel for a Mars expedition from the lunar surface is often suggested, but it's hard to make it pay off - Moon bases are expensive, and just buying more rockets to launch fuel from Earth is relatively cheap.

Believe in yourself, step one. Believe in the order, step two. Believe in the teachings, step three.
Every time I step onto an airplane, I turn to the right and take a good, hard stare into the maw of the engine. I don't know what I'm looking for. I just do it.
Here is the first step toward success. It's a basic step. It can't be avoided. Step One: Believe in yourself, believe you can succeed.
