Steve Squyres, principal investigator for NASA’s Mars Exploration Rover mission, and Matt Golombek, the mission’s project scientist, discussed the ground-breaking science returned by the mission’s ...

This image is a cropped version of the last 360-degree panorama taken by the Opportunity rover's Pancam from May 13 through June 10, 2018. The panorama appears in 3D when seen through blue-red glas...

The boulder-studded ridge in this scene recorded by NASA's Mars Exploration Rover Opportunity is "McClure-Beverlin Escarpment," informally named for Jack Beverlin and Bill McClure, engineers who on...

This stereo scene from NASA's Mars Exploration Rover Opportunity shows "Spirit Mound" overlooking the floor of Endeavour Crater. The view appears three-dimensional when seen through blue-red glasse...

Road trip! This compilation of images from hazard-avoidance cameras on NASA's Mars Exploration Rover Opportunity between January 2004 and April 2015 shows the rover's-eye-view of the Martian marath...

As NASA's Mars Exploration Rover Opportunity creeps farther into "Endurance Crater," the dune field on the crater floor appears even more dramatic

These images of a sand "ripple" were acquired by Opportunity using its panoramic camera on sol 644 and its navigation camera on sol 645.

This image shows a portion of the rim of "Erebus Crater" in the Meridiani Planum region of Mars.

Buzz Aldrin, an Apollo 11 astronaut who walked on the moon, makes a holographic appearance in 'Destination: Mars,' a mixed-reality tour of a part of Mars that NASA's Curiosity rover has explored.

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.

This series of images, taken by the Opportunity rover in July 2007, shows a darkening sky as a huge regional dust storm covered both Opportunity and her twin rover, Spirit.

This false-color image taken by Spirit shows a group of darker rocks dubbed "Toltecs," lying to the southeast of the rover's position.The rocks are believed to be basaltic, or volcanic, in composit...

This scene from the panoramic camera (Pancam) on NASA's Mars Exploration Rover Opportunity looks back toward part of the west rim of Endeavour Crater that the rover drove along, heading southward, ...

This June 2017 view from the Pancam on NASA's Opportunity Mars rover shows the area just above "Perseverance Valley" on the western rim of Endeavour Crater. Color has been enhanced to make diffe...

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.

This is the Spirit panoramic camera's "Lookout" panorama, acquired on the rover's 410th to 413th martian days, or sols (Feb. 27 to Mar. 2, 2005).

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

"Marathon Valley" on Mars opens to a view across Endeavour Crater in this scene from the Pancam of NASA's Mars rover Opportunity. The scene merges many exposures taken during April and May 2016. Th...
