Chris Herwig, a data analyst at MapBox, has started and published an interesting mapping project. He started mapping the planet Mars. To be able to do this open data comes into play from NASA / JPL, USGS and various other (academic) sources.
The result is a visually attractive way to explore the red planet, see where the various landings have taken place, and where the mars rover Curiousity is going.
All map sources have also been made available again...
