This image was taken on June 3, 2008 to examine dust that had fallen onto an exposed surface. The translucent particle highlighted at bottom center is of comparable size to white particles in a Martian soil sample (upper pictures) seen two sols earlier inside the scoop of Phoenix's Robotic Arm as imaged by the lander's Robotic Arm Camera. The white particles may be examples of the abundant salts found in the Martian soil by previous missions. Credit: NASA/JPL-Caltech/University of Arizona
