NASA's Opportunity rover appears as a blip in the center of this square. This image taken by HiRISE, a high-resolution camera onboard NASA's Mars Reconnaissance Orbiter, shows the dust storm over P...

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

This March 21, 2016, image from the navigation camera on NASA's Mars rover Opportunity shows streaks of dust or sand on the vehicle's rear solar panel after a series of drives during which the rove...

After driving uphill about 139 feet (42.5 meters) during the 3,485th Martian day, or sol, of its work on Mars (Nov. 12, 2013), NASA's Mars Exploration Rover Opportunity captured this image with its...

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...

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

NASA's Mars Exploration Rover Opportunity captured this view after beginning to ascend the northwestern slope of "Solander Point" on the western rim of Endeavour Crater.

This self-portrait from Opportunity shows dust accumulation on the rover's solar panels as the mission approached its fifth Martian winter.

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 image taken by the panoramic camera onboard Opportunity shows the rover's now-empty lander, the Challenger Memorial Station, at Meridiani Planum, Mars.

This image superimposes an artist's concept of the Mars Exploration Rover Opportunity on the rim of Victoria Crater. It is done to give a sense of scale.

Results from Opportunity and Curiosity show Mars could have supported life.

Mars Exploration Rover parachute deployment testing

While driving eastward toward the northwestern flank of "McCool Hill," the wheels of NASA's Mars Exploration Rover Spirit churned up the largest amount of bright soil discovered so far in the mission

Navigators may know best that "life is all about the journey." For seven grueling months, the navigators for Spirit and Opportunity have been analyzing millions of lines of data and fine-tuning the...

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 ...

The component images for this stereo, 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 t...

Researchers used the panoramic camera (Pancam) on NASA's Mars Exploration Rover Opportunity to capture this view of comet C/2013 A1 Siding Spring as it passed near Mars on Oct. 19, 2014.

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...

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 artist's rendering depicts NASA's Mars Exploration Rovers, Spirit and Opportunity. The twin rovers were launched in 2003 and arrived on Mars in January 2004.

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.
