Curiosity: ChemCam Data...

At right is the first spectrograph made by Curiosity's ChemCam, when it zapped “Coronation Rock” with its megawatt laser.  From this, geologists can read a detailed description of Coronation Rock's mineral make up. 

With this first test run of ChemCam, Curiosity has already returned more hard science data than the ISS has done in its entire existence.  I sure wish we'd concentrate our government spending on space on this sort of mission, and stop wasting it with purposeless manned missions...
