Scenes from Space #44

I don't know if any of you have been following all of the data coming from Mars these days, but they are finding lots of interesting new things. The MRO (Mars Reconnaissance Orbiter) used radar to find something pretty interesting - huge glaciers under the surface. It looks like each of these glaciers might cover an area larger than a city, and be almost a kilometer thick. This discovery could have serious effect on the planning of a future mission to Mars, and could even serve as a drinking water reservoir for a future Martian settlement.
