This image released on Wednesday Aug. 8, 2012 by NASA, shows a mosaic of the first two full-resolution images of the Martian surface from the Navigation cameras on NASA's Curiosity rover. The rim of Gale Crater can be seen in the distance beyond the pebbly ground.   The foreground shows two distinct zones of excavation likely carved out by blasts from the rover's descent stage thrusters. (AP Photo/NASA)
