Curiosity rover explores Mars

This handout photo provided by NASA/JPL-Caltech shows the surroundings of the location where NASA Mars rover Curiosity arrived on Sept. 4, 2012. It is a mosaic of images taken by Curiosity's Navigation Camera (Navcam) following the Sol 29 drive of 100 feet. Tracks from the drive are visible in the image.

This handout photo provided by NASA/JPL-Caltech shows the surroundings of the location where NASA Mars rover Curiosity arrived on Sept. 4, 2012. It is a mosaic of images taken by Curiosity's Navigation Camera (Navcam) following the Sol 29 drive of 100 feet. Tracks from the drive are visible in the image. For scale, Curiosity leaves parallel tracks about 9 feet apart. The rover Curiosity is making its mark on Mars. Its tracks are big enough to be seen from space. In just one month, the car-sized rover has driven 368 feet on the red planet. That's slightly more than the length of a football field. Curiosity's slightly zig-zaggy tire tracks were photographed from a NASA satellite circling Mars and also from the rover's rear-facing cameras. Curiosity landed on Aug. 5.
