Even More Eye-popping 'Berries'
This 3-D image from the Mars Exploration Rover Opportunity rover shows an extreme close-up of round, blueberry-shaped grains on the crater floor near the rock outcrop at Meridiani Planum called Stone Mountain. Scientists are studying these curious formations for clues about the soil's history. The observed area is 3 centimeters (1.2 inches) across. (Courtesy NASA/Cornell/USGS)

Berries on the Ground
This is the 3-D anaglyph showing a microscopic image taken of soil featuring round, blueberry-shaped rock formations on the crater floor at Meridiani Planum, Mars. This image was taken on the 13th day of the Mars Exploration Rover Opportunity's journey, after the Moessbauer spectrometer, an instrument located on the rover's instrument deployment device, or "arm," was pressed down to measure the soil's iron mineralogy. Note the donut-shaped imprint of the instrument in the lower part of the image. The area in this image is approximately 3 centimeters (1.2 inches) across. (Courtesy NASA/Cornell/USGS/Texas A&M)

3-D Rocky Outcrop
This 3-D image was captured by the Mars Exploration Rover Opportunity's Panoramic camera. It shows part of the rocky outcrop within the crater Opportunity landed in. The image was created by combining left and right image pairs. (Courtesy NASA/Calvin J. Hamilton)

Vacant Lander in 3-D
This 3-D image captured by the Mars Exploration Rover Opportunity's rear hazard-identification camera shows the now-empty lander that carried the rover 283 million miles to Meridiani Planum, Mars. Engineers received confirmation that Opportunity's six wheels successfully rolled off the lander and onto martian soil at 3:01 a.m. PST, January 31, 2004, on the seventh martian day, or sol, of the mission. The rover is approximately 1 meter (3 feet) in front of the lander, facing north. (Courtesy NASA/JPL/Cornell)

Not of this Earth 3D
This sweeping look at the unusual rock outcropping near the Mars Exploration Rover Opportunity was captured by the rover's left and right panoramic cameras to generate this 3D image. Scientists believe the layered rocks are either volcanic ash deposits, or sediments laid down by wind or water. Opportunity landed at Meridiani Planum, Mars on January 24 at 9:05 p.m. PST.
