Ok, good, I thought that was what you meant but wasn't really sure.

Yep, I agree, we do need to study both the Kuiper belt and the Oort Cloud before we can progress much further from the sun.

What about the moons of other planets in the solar system that have shown signs of geologic activity, or even hints towards the existence of water, such as on Pluto's moon, Charon? Or Uranus' moon Miranda?

While it is really impractical to try to colonize these celestial bodies, it is interesting to see, and know, that we aren't the only thing orbiting the sun to have water on it.
