Near the lower left corner of this view is the three-petal lander platform that NASA's Mars Exploration Rover Spirit drove off in January 2004. The lander is still bright, but with a reddish color, probably due to accumulation of Martian dust.
The total distance driven on Mars by NASA's Mars Exploration Rover, 21.35 miles by early December 2011, is approaching the record total for off-Earth driving, held by the robotic Lunokhod 2 rover operated on Earth's moon by the Soviet Union in 1973.
This map shows the path that NASA's Mars Exploration Rover Opportunity followed from the 1,813th Martian day, or sol, to Sol 2450 (Dec. 15, 2010) when Opportunity approached a crater informally named 'Santa Maria.'
This map shows the path that NASA's Mars Exploration Rover Spirit followed from the 743rd Martian day (Feb. 4, 2009), or sol, to Sol 2471 (Dec. 15, 2010). Spirit has been at a sand-trap location called 'Troy' since April 2009.
Soil Disturbed by Spirit Drives Before Fourth Martian Winter (False Color)
This mosaic of images shows the soil in front of NASA's Mars Exploration Rover Spirit after a series of short backward drives during attempts to extricate the rover from a sand trap in January and early February 2010.
Lengthy detective work from data collected by NASA's rover Spirit confirmed that an outcrop called 'Comanche' contains a mineral indicating that a past environment was wet and non-acidic, possibly favorable to life.
Spirit's Rear View After Parking for Fourth Winter
NASA's Mars Exploration Rover Spirit recorded this fisheye view after completing a drive during on Mars on Feb. 8, 2010. The drive left Spirit in the position where the rover will stay parked during the upcoming Mars southern-hemisphere winter.
Front Camera View of Backward Drive, Sols 2145-2154
This NASA Spirit image view is toward the north, looking down at Spirit's front wheels. It is one of a series of wide-angle views shown one after the other. Go to the Photojournal to view the animation.
Rear Camera View of Backward Drive, Sols 2145-2154
This NASA Spirit image view is toward the south, looking down at Spirit's rear wheels. It is one of a series of wide-angle views shown one after the other. Go to the Photojournal to view the animation.
This image is one of two frames showing NASA's Spirit driving backward as next technique for attempting to extricate the rover from the sand trap where it is embedded. Go to the Photojournal for the animation.
This frame (taken from a three-frame animation) aids evaluation of performance of the right-front wheel on NASA's Mars Exploration Rover Spirit during a drive on the rover's 2,117th Martian day, or sol (Dec. 16, 2009).
Slight Movement by Spirit's Right-Front Wheel, Sol 2113
Diagnostic tests were run on the right-rear wheel and right-front wheel on NASA's Spirit. The right-rear wheel continued to show no motion in the latest tests and exhibited very high resistance in the motor winding.
This view from the navigation camera near the top of the mast on NASA's Mars Exploration Rover Spirit shows the tracks left by the rover as it drove southward and backward, dragging its inoperable right-front wheel.
NASA's Mars Exploration Rover Spirit recorded this forward view of its arm and surroundings; bright soil in the left half of the image is loose, fluffy material churned by the rover's left-front wheel as Spirit.
'Calypso' Panorama of Spirit's View from 'Troy' (Stereo)
This full-circle view from the panoramic camera (Pancam) on NASA's Mars Exploration Rover Spirit shows the terrain surrounding the location called 'Troy,' where Spirit became embedded in soft soil during the spring of 2009. 3D glasses are necessary.
Spirit's View of Own Underbelly, (Sol 1925 Stereo)
This stereo view combines a pair of images taken by the microscopic imager on NASA's Mars Exploration Rover Spirit during the 1,925th Martian day (sol) of Spirit's mission on Mars (June 2, 2009). 3D glasses are necessary to view this image.
Testing at NASA's Jet Propulsion Laboratory in August 2009 is assessing possible maneuvers that the Mars rover Spirit might use for escaping from a patch of soft soil where it is embedded at a Martian site called 'Troy.'
