Mars: water aplenty

Tired and thirsty from a hard day of terraforming Mars? Why not kick back with a glass of cool, refreshing martian water. It's chemically trapped in iron sulphates and has the consistency of drywall, but hell, it's still water. Scientists of the University of Guelph have discovered evidence of mass amounts of water just milimetres beneath the martian surface. Trouble is, it's chemically bonded to a layer of mineral salts. Still, the chalky residue is about 18 per cent water by volume.

It was discovered when a wheel locked up on the martian rover Spirit. The gimpy wheel digs a deep gouge as the rover travels around, and revealed the watery substrate.

All of this is great news for the colonization of Mars. With tonnes of water just under the surface, colonists could easily process the mineral salts and extract the precious H2O. Provided, of course, they can survive the myriad other dangers on martian surface: three-fingered goons with heat rays, inexplicable tornado machines left by long-dead civilizations, and, apparently, the Transformers.
