Follow the Water

This here looker is the moon Enceladus, a satellite of Saturn. The moon is getting tons of attention of late as it's now definitive Enceladus is filled to the brim with water. Real water too, none of that artsy Space Water. The blue in this photo is the water, which is frozen - very - at the surface, yet is clearly liquid at some depth below the surface, because it ejects all the time in the form of massive water geysers, as such: 

 Enceladus orbits very close to Saturn, and in fact is responsible for one of Saturn's rings, as the water that ejects from the moon then goes into orbit around Saturn as a ring.

This moon will no doubt eventually serve as a refueling station for long haul space truckers.
Eventually...
