Mars Exploration Rover team members with rover

This beautiful scene reveals a tremendous amount of detail in Spirit's surroundings at a place called "Winter Haven," where the rover spent many months parked on a north-facing slope in order to ke...

This collage shows the variety of soils found at landing sites on Mars.

This map show a portion of Endeavour Crater's western rim that includes the "Marathon Valley" area investigated intensively by NASA's Mars Exploration Rover Opportunity in 2015 and 2016, and a flu...

This is a look inside a soil trench or drift dubbed 'Serpent' after the rover successfully dug into the side of the drift.

Cumulative driving by NASA's Mars Exploration Rover Opportunity surpassed marathon distance on March 24, 2015, as the rover neared a destination called "Marathon Valley," which is middle ground of ...

This 360-degree stereo anaglyph of the terrain surrounding NASA's Mars Exploration Rover Opportunity was taken on the rover's 171st sol on Mars (July 17, 2004).

This graph compares the elemental composition of typical soils at three landing regions on Mars.

Eleven years and two months after its landing on Mars, the total driving distance of NASA's Opportunity Mars rover surpassed the length of a marathon race: 26.219 miles (42.195 kilometers). This ma...

Opportunity's wheels dug more than 10 centimeters (4 inches) deep into the soft, sandy material of a wind-shaped ripple in Mars' Meridiani Planum region during the rover's 446th martian day, or sol...

Team members reflect on Spirit's six-years of roving Mars.

This Aug. 15, 2014, scene from the Pancam on NASA's Mars Exploration Rover Opportunity looks back toward part of the west rim of Endeavour Crater that the rover drove along, heading southward, duri...

A grooved ridge called "Rocheport" on the rim of Mars' Endeavour Crater spans this scene from the Pancam on NASA's Mars rover Opportunity. The view extends from south-southeast on the left to north...

This self-portrait of NASA's Mars Exploration Rover Opportunity comes courtesy of the Sun and the rover's front hazard-avoidance camera.

In February 2015, NASA's Mars Exploration Rover Opportunity is approaching a cumulative driving distance on Mars equal to the length of a marathon race. This map shows the rover's position relative...

This stereo anaglyph looking toward the northeast across "Endurance Crater" in Mars' Meridiani Planum region was assembled from frames taken by the navigation camera on NASA's Mars Exploration Rove...

Drive along with NASA’s Opportunity Mars rover and hear the voices of scientists and engineers behind the mission. Designed to run for 90 days, the exploration spanned more than 15 years from 2004 ...

On the 20th anniversary of the landing of Spirit and Opportunity, celebrate NASA’s Mars Exploration Rover Project with this two-sided poster that lists some of the pioneering explorers’ accomplishm...

This 360-degree stereo anaglyph of the terrain surrounding NASA's Mars Exploration Rover Spirit on the 147th martian day of the rover's mission inside Gusev Crater, on June 1, 2004, was assembled f...

Born together, the Spirit and Opportunity twin rovers followed divergent paths after they landed on opposite sides of Mars. Opportunity’s journey was marked by good fortune, while Spirit’s was trou...

This bird's-eye view combines a self-portrait of the spacecraft deck and a panoramic mosaic of the Martian surface as viewed by the Spirit rover.

The yellow line on this map shows where NASA's Mars Rover Opportunity has driven from the place where it landed in January 2004 -- inside Eagle crater, at the upper left end of the track -- to a po...

Spirit used its microscopic imager to capture these spectacular, jagged mini-landscape on a rock called "GongGong." Wind has deposited sand and dust in the holes and crevices of the rock.

Wheel tracks from NASA's Mars rover Opportunity descending and departing the "Cape Tribulation" segment of Endeavour Crater's rim are visible in this April 21, 2017, view from the rover's Pancam. T...

NASA's Mars Exploration Rover Opportunity observed this outcrop on the "Murray Ridge" portion of the rim of Endeavour Crater as the rover approached the 10th anniversary of its landing on Mars.

This image is an edited version of the last 360-degree panorama taken by the Opportunity rover's Pancam from May 13 through June 10, 2018. The version of the scene is presented in approximate true ...
