Mars Global Surveyor Recap

ScottMaxwell writes: "Though the date passed with little notice, JPL's Mars Global Surveyor spacecraft recently completed its primary mission, to study Mars for a full Martian year (about 687 Earth days). It's returned more mission data than all previous Mars missions combined, including some of the best evidence yet that water once flowed freely on the Martian surface. Check out the project's Web site for more info and images (including my personal favorite) as MGS moves into its extended mission."
