6th Year Anniversary Graphic

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 panorama is the view NASA's Mars Exploration Rover Opportunity gained from the top of the "Cape Tribulation" segment of the rim of Endeavour Crater. The rover reached this point three weeks be...

At a rock called "Clovis," the rock abrasion tool on Spirit cut a 9-millimeter (0.35-inch) hole. To the right of the drill hole is a "brush flower" of circles produced by scrubbing the surface of...

While driving eastward toward the northwestern flank of "McCool Hill," Spirit's wheels churned up the largest amount of bright soil discovered to that point in the mission. This image from Spirit's...

What looks like the rover "neck and head" is called the Pancam Mast Assembly.

These views of Mars are just a small sampling from the 124,000 images returned by the Spirit rover. (Audio: music only)

Divide and conquer: combining 11 small sections of "Block Island" (the color map shows five of the sections).

This map updates progress that NASA's Mars Exploration Rover Opportunity is making toward reaching a driving distance equivalent to a marathon footrace. It indicates the rover's position on March 2...

This view captured by Spirit called "Legacy" panorama, combines images taken between the landing site and the rim of "Bonnevile Crater."

This full-circle, stereo panorama shows the terrain around the NASA Mars Exploration Rover Opportunity during the 3,071st Martian day, or sol, of the rover's work on Mars (Sept. 13, 2012).

This kickoff of a new Mars video series covers Opportunity's 14th anniversary on the Red Planet, Curiosity's spectacular panorama and ice deposits spotted by an orbiter.

This image is an approximately true color rendering of the slope of "Endurance Crater," which the Opportunity rover explored in 2004.

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...

A grooved ridge called "Rocheport" on the rim of Mars' Endeavour Crater spans this scene from the Pancam on NASA's Mars rover Opportunity. This version of the scene is presented in enhanced color t...

This June 2017 view from the Pancam on NASA's Opportunity Mars rover shows the area just above "Perseverance Valley" on a large crater's rim. A broad notch in the crest of the rim, at right, mig...

Engineers for NASA's Mars Exploration Rover Mission are completing assembly and testing for the twin robotic geologists at JPL.

NASA's Mars Exploration Rover Spirit has this view northward from the position at the north edge of the "Home Plate" plateau where the rover will spend its third Martian winter.

These two thumbnail images, with the ghostly dot of a faint Sun near the middle of each, are the last images NASA's Opportunity rover took on Mars.

Two generations of Rovers.

Some of the team members from NASA's Mars Exploration Rover project were still in college -- or even high school -- when the rovers landed in 2004. Hear their stories of becoming part of this remar...

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...

The component images for this 360-degree panorama were taken by the navigation camera on NASA's Mars Exploration Rover Opportunity after the rover drove about 97 feet (29.5 meters) during the missi...

This close-up view of a target rock called "Last Chance" was acquired by the microscopic imager on the arm of NASA's Mars Exploration Rover Opportunity on March 3, 2004, during the 39th Martian day...

As NASA's Mars Exploration Rover Opportunity neared the ninth anniversary of its landing on Mars, the rover was working in the 'Matijevic Hill' area seen in this stereo view from Opportunity's pano...

As part of its investigation of "Victoria Crater," Opportunity examined a promontory called "Cape Verde" from the vantage point of "Cape St. Mary," the next promontory clockwise around the crater's...
