NASA's Mars Exploration Rover Opportunity used its navigation camera to take the images combined into this 360-degree view of the rover's surroundings on the 1,850th Martian day, or sol, of its surface mission (April 7, 2009).

Researchers used the navigation camera on NASA's Mars Exploration Rover Spirit to look for dust devils near the rover during the mission's 1,919th Martian day, or sol (May 27, 2009).
While the panoramic camera (Pancam) on NASA's Mars Exploration Rover Spirit was taking exposures with different color filters during the 1,919th Martian day of the rover's mission (May 27, 2009), dust devils moved across the field of view.
The navigation camera on NASA's Mars Exploration Rover Spirit caught this stereo view of a dust devil during the 1,913th Martian day, or sol, of the rover's mission on Mars (May 21, 2009).
Mars Exploration Rover team members at NASA's Jet Propulsion Laboratory, Pasadena, Calif., prepare an experiment on July 13, 2009, for assessing how a test rover moves when embedded in loose soil and commanded to drive backward with wheels turned.
Mars Exploration Rover team members prepare a testing setup for a subsequent experiment after an experiment driving the rover in a crablike motion, with all four corner wheels angled to the right.
Mike Seibert and Sharon Laubach, engineers on the Mars Exploration Rover team at NASA's Jet Propulsion Laboratory, Pasadena, check the exact position of a test rover in preparation for the next test of a possible maneuver for Spirit to use on Mars.
After commanding five of a test rover's six wheels to drive forward, rover driver Paolo Bellutta measures how much the rover moved sideways, downslope, during the maneuver.
The soft soil exposed when wheels of NASA's Mars Exploration Rover Spirit dug into a patch of ground dubbed "Troy" exhibit variations in hue visible in this image, in which the colors have been stretched to emphasize the differences.

Where Are The Rovers Now? Spirit's traverse map through Sol 1928. As of Sol 1926, Spirit's total odometry remains at 7,729.93 meters (4.80 miles).
This panorama of images from the Spirit rover is helping engineers assess the rover's current state and plan her extraction from the soft soil in the region now called "Troy."

Similar to a geologist's hand lens, the microscopic imager on NASA's Mars Exploration rovers is designed to image objects at a close distance (less than a few centimeters) at very high resolution.
Wheel slippage during attempts to extricate NASA's Mars Rover Spirit from a patch of soft ground during the preceding two weeks had partially buried the wheels.
As of Sol 1892 (April 29, 2009), Spirit's total odometry is 7,729.73 meters (4.80 miles).
NASA's Mars Exploration Rover Spirit slipped in soft ground during short backward drives on the 1,886th and 1,889th Martian days, or sols, of the rover's mission on Mars (April 23 and 26, 2009).
