Mars Exploration Rover team members with rover

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 position on March 5, ...

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.

The first episode documents the hurdles leading up to both launches. From Mother Nature being uncooperative to a problem with the cork insulation on the rocket, lift-off was no small feat. Ultimate...

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...

On the horizon in the right half of this panoramic view is an area of Mars informally named "Matijevic Hill," in commemoration of an influential rover-team leader.

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...

Researchers used NASA's Mars Exploration Rover Opportunity to find a water-related mineral on the ground that had been detected from orbit, and found it in the dark veneer of rocks on the rim of En...

NASA's Mars Rover Opportunity catches its own late-afternoon shadow in this dramatically lit view eastward across Endeavour Crater on Mars.

Taken on June 10, 2018 (the 5,111th Martian day, or sol, of the mission) this “noisy,” incomplete image was the last data NASA's Opportunity rover sent back from Perseverance Valley on Mars. 

This image from the panoramic camera (Pancam) on NASA's Mars Exploration Rover Opportunity shows where a rock called "Pinnacle Island" had been before it appeared in front of the rover in early Jan...

This false-color 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.

This scene from NASA's Mars rover Opportunity shows "Wharton Ridge," on the western rim of Endeavour Crater. The ridge's name honors the memory of astrobiologist Robert A. Wharton (1951-2012). The ...

This enhanced-color view of ground sloping downward to the right in "Perseverance Valley" shows textures that may be due to abrasion by wind-driven sand. The Pancam on NASA's Mars rover Opportunity...

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.

Spirit acquired this mosaic while investigating the area east of the elevated plateau known as "Home Plate" in the "Columbia Hills." The trench exposed a patch of nearly pure silica, with the comp...

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.

Researchers used NASA's Mars Exploration Rover Opportunity to find a water-related mineral on the ground that had been detected from orbit, and found it in the dark veneer of rocks on the rim of En...

This illustration depicts some highlights along the route as NASA's Mars Exploration Rover Opportunity drove as far as a marathon race during the first 11 years and two months after its January 200...

This image from the panoramic camera on NASA's Mars Exploration Rover Opportunity shows a rock called "Chocolate Hills," which the rover found and examined at the edge of a young crater called "Con...

A "Martian mechanic" checks beneath the completely deployed Rover 1 lander. Atop the lander is Rover 1 with its wheels and solar arrays in the stowed position.

This July 18, 2017, image from the navigation camera (Navcam) on the mast of NASA's Mars Exploration Rover Opportunity provides a look back to the crest of Endeavour Crater's rim after the rover be...

This 360-degree panorama was taken by "Dusty," a fully-working replica of NASA's Opportunity rover at the agency's Jet Propulsion Laboratory. The panorama was taken as part of a software test. Memb...

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.
