A nice cool drink in the sandy dunes. Of Mars.

"Scientists have found evidence that large amounts of water-ice hide within massive sand dunes on Mars. One of the dunes, which spans 6.5km and rises 475m above the Martian surface, may be the single largest sand dune in the entire Solar System. The icy dunes could be a valuable resource for any future manned missions to the planet, said Dr Mary Bourke.

The researcher presented her results to a science conference in Dublin. "If you're looking for a source of water for any future landers," said Dr Bourke, "I am advocating that you march up to your nearest sand dune."
