This image taken by Phoenix's robotic arm camera on July 9, 2008, the 44th Martain day, or sol, of the mission shows several cracks that have developed in the Snow Queen feature just under the lander, as well as a pebble or clod of dirt that has appeared. The Phoenix team carefully positioned and focused RAC the same way in both images. Credit: NASA/JPL-Caltech/University of Arizona/Max Planck Institute
