NASA's Mars Exploration Rover Opportunity recorded this stereo view of the summit of "Cape Tribulation," on the western rim of Endeavour Crater, on the day before the rover drove to the top. The sc...

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.

NASA's Opportunity rover captured an image of this rock nicknamed "Jornada del Muerto" while in Perseverance Valley. The wind-carved streaks along its face were very similar to rocks seen at the ri...

This stereo view was assembled from images taken by the navigation camera on NASA's Mars Exploration Rover Spirit during the rover's 337th martian day, or sol (Dec. 14, 2004). Spirit's position, ca...

This scene from NASA's Mars Exploration Rover Opportunity shows "Lunokhod 2 Crater," which lies south of "Solander Point" on the west rim of Endeavour Crater.

A portion of an exposure of bedrock dubbed "Larry's Outcrop" shows little layering in this view, in contrast to nearby outcrops called "Methuselah" and "Jibsheet."

This view combines frames taken by the panoramic camera on Opportunity's 652nd through 663rd Martian days, or sols (Nov. 23 to Dec. 5, 2005), at the edge of "Erebus Crater."

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

Members of the Mars Exploration Rover Mission's Entry, Descent and Landing team rejoice at the news that mission control received its first signal from Spirit, indicating the rove...

This image from the front hazard-avoidance camera (Hazcam) on the NASA Mars Exploration Rover Opportunity shows the rover's arm extended for examination of a target called "Onaping" at the base of ...

This synthetic image of the Spirit Mars Exploration Rover on the flank of "Husband Hill" was produced using "Virtual Presence in Space" technology.

This chart illustrates comparisons among the distances driven by various wheeled vehicles on the surface of Earth's moon and Mars.  

Artist's concept of controlling the rover from Earth, scientists drive the rover along Mars' surface inspecting geological features.

This May 29, 2016, image of a target called "Private Joseph Field" combines images from the microscopic imager on NASA's Mars Exploration Rover Opportunity with enhanced color information from the ...

This grouping of two test rovers and a flight spare provides a graphic comparison of three generations of Mars rovers developed at NASA's Jet Propulsion Laboratory, Pasadena, Calif. The setting is ...

On Earth, a fast runner takes a few hours to complete a marathon. On Mars, it's taken 11 years. NASA's Opportunity rover crossed that finish line in 2015.

Two spacecraft engineers join a grouping of vehicles providing a comparison of three generations of Mars rovers developed at NASA's Jet Propulsion Laboratory, Pasadena, Calif. The setting is JPL's ...

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...

As Opportunity crept farther into "Endurance Crater," the dune field on the crater floor appeared even more dramatic.

This full-circle scene combines 817 images taken by the panoramic camera (Pancam) on Opportunity.

In this selfie, Spirit shows her solar panels gleaming in the Martian sunlight and carrying only a thin veneer of dust two years after the rover landed and began exploring the red planet.

This global map of Mars shows a growing dust storm as of June 6, 2018. The map was produced by the Mars Color Imager (MARCI) camera on NASA's Mars Reconnaissance Orbiter spacecraft.
