Watering Holes

Rosetta has been circling a comet in deep space for several weeks now, its purpose is to get a crystal clear image of the comet itself, on all sides. This, in order to land a craft on the spinning space debris. Once they have treads on the ground they can begin a more careful study of the chemical composition of the comet and what it might hold for the future.

Much like watering holes in the desert, comets can serve as way stations in space travel. The chunks of ice are everywhere and if they can be habitable, or at least craft put in orbit around the, then other craft can stop by and harvest their water and move on.

Rosetta should have enough information for the ESA to make their final call on the site this month.
