Mars Exploration Rover team members with rover

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...

An oblique, northward-looking view based on stereo orbital imaging, shows the location of Opportunity on its journey from Cape York to Solander Point when HiRISE took the new color image.

Details of the Gusev Crater designated landing site are added with topographic information and higher-resolution imaging from instruments on the Mars Global Surveyor and Mars Odyssey orbiters.

Opportunity found an iron meteorite on Mars, the first meteorite of any type ever identified on another planet.

A dance-step pattern is visible in the wheel tracks near the left edge of this scene recorded in stereo by the navigation camera on NASA's Mars Exploration Rover Opportunity during the 2,554th Mart...

The target beneath the tool turret at the end of the rover's robotic arm in this image from NASA's Mars Exploration Rover Opportunity is "Private John Potts." It lies high on the southern side of "...

Artist's concept of rover using the rock abrasion tool (RAT) on the robotic arm grinds away the rock's surface, allowing scientific instruments to analyze the rock's interior.

This stereo view was taken by the panoramic camera on NASA's Mars Exploration Rover Spirit on the rover's 87th martian day, or sol (April 1, 2004), just after Spirit left "Bonneville Crater." It sh...

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 infographic highlights NASA’s twin robot geologists, the Mars Exploration Rovers (MER) Spirit and Opportunity.  The rovers landed on the Red Planet in 2004, in search of answers about the hist...

This rock, dubbed "Gasconade," was investigated by NASA's Mars Exploration Rover Opportunity while the rover was perched on "Spirit Mound" at the western edge of Mars' Endeavour Crater. Four Oct. 2...

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...

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.

From its perch high on a ridge, NASA's Mars Exploration Rover Opportunity recorded this image of a Martian dust devil twisting through the valley below.

If a human with perfect vision donned a spacesuit and stepped onto the martian surface, the view would be as clear as this sweeping panorama taken by Spirit.

Spirit examined spectacular layered rocks exposed at "Home Plate."

This image shows the location of the rover-containing section of new color image in relation to Solander Point.

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

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...

This image shows segments of the western rim of Mars' Endeavour Crater. NASA's Mars rover Opportunity has explored parts of the rim since 2011. The view covers an area about 9 miles wide. It was ta...

The nose cone of the rocket separates during the launch phase and the Mars Exploration Rover is sent on a seven-month journey to Mars.

Bekah Sosland was an eighth-grade student in Fredericksburg, Texas, when NASA's Mars Exploration Rovers Spirit and Opportunity landed on Mars in January 2004.

"Marathon Valley" on Mars opens northeastward in this stereo version of a scene from the Pancam of NASA's Mars Exploration Rover Opportunity. The scene, recorded in April and May 2016, appears thre...

NASA's Opportunity Mars rover passed near this small, relatively fresh crater in April 2017, during the 45th anniversary of the Apollo 16 mission to the moon. The rover team chose to call it "Orion...
