Liquid water, salt likely on Saturn's small moon

Nasa's Cassini spacecraft has obtained strong evidence that Saturn's tiny moon Enceladus retains liquid water.
The probe has detected sodium salts in the vicinity of the satellite, which appear to spew from its south pole.
Liquid water that is in prolonged contact with rock will leach out sodium - in exactly the same way as Earth's oceans have become salty over time.
Scientists tell Nature magazine that the liquid water may reside in caverns just below the surface of the moon.
If confirmed, it is a stunning result. It means the Saturnian satellite may be one of the most promising places in the Solar System to search for signs of extraterrestrial life.

Good in terms of possible life. Good in terms of colonization. Liquid water is needed for practically all industrial processes. It's very energy-intensive to create or transport water (it's very heavy as you probably know if you've every carried an aquarium), but if it's all there, that solves a big problem. Of course the small moon has other issues (lack of atmosphere and magnetic field) but it's less problematic than a moon thick with poisonous gases and no liquid water to speak of.

Well if we accelerate our technology at a rate that I think we should, it won't be long before we think about this. We can only colonize Mars on the poles because that's the only place where water is likely.

I think we should at least send a follow-up probe to do more in-depth analysis of this.
