This pair of images from the Mast Camera on NASA's Curiosity rover shows the upper portion of a wind-blown deposit dubbed "Rocknest." The rover team recently commanded Curiosity to take a scoop of soil from a region located out of frame, below this view. The soil was then analyzed with the Chemistry and Mineralogy instrument, or CheMin.
The colors in the image at left are unmodified, showing the scene as it would appear on Mars, which has a dusty red-colored atmosphere. The image at right has been white-balanced to show what the same area would look like under the lighting conditions on Earth.
The rounded rock located at the upper center portion of the images is about 8 inches (0.2 meters) across.
JPL manages the Mars Science Laboratory/Curiosity for NASA's Science Mission Directorate in Washington. The rover was designed, developed and assembled at JPL, a division of the California Institute of Technology in Pasadena.
