Maybe water is not only on our planet.

> For more than a decade, Colin Dundas, a geologist at the U.S. Geological Survey in Flagstaff, Arizona, has had a daily routine: inspecting a dozen or so high-resolution images beamed back every day from the Mars Reconnaissance Orbiter (MRO). A few years ago, something surprising popped out from the planet’s sea of rust: a pale sliver of blue.
What Dundas saw that day, and subsequently found at seven other sites, are steep cliffs, up to 100 meters tall, that expose what appears to be nearly pure ice. The discovery points to large stores of underground ice buried only a meter or two below the surface at surprisingly low martian latitudes. “This kind of ice is more widespread than previously thought,” says Dundas, who, with his co-authors, describes the cliffs this week in Science. Each cliff seems to be the naked face of a glacier, tantalizing scientists with the promise of a layer-cake record of past martian climates and space enthusiasts with a potential resource for future human bases.
