Researchers used the panoramic camera (Pancam) on NASA's Mars Exploration Rover Opportunity to capture this 10-second-exposure view of comet C/2013 A1 Siding Spring as it passed near Mars on Oct. 1...

NASA's Mars Exploration Rover Opportunity used its navigation camera to capture the component images for this 360-degree view near the ridgeline of Endeavour Crater's western rim.

This false color image suggests that the plains beyond the small crater where the Mars Exploration Rover Opportunity now sits are littered with the same dark grey material found inside the crater i...

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 from the panoramic camera (Pancam) on NASA's Mars Exploration Rover Opportunity shows the location of a rock called "Pinnacle Island" before it appeared in front of the rover in early Ja...

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 image is an approximately true color rendering of the slope of "Endurance Crater," which the Opportunity rover explored in 2004.

The left image shows an extreme close-up of round, blueberry-shaped formations in the martian soil near a part of the rock outcrop at Meridiani Planum called Stone Mountain.

This graphic shows how the energy available to NASA’s Opportunity rover on Mars (in watt-hours) depends on how clear or opaque the atmosphere is (measured in a value called tau). When the tau value...

This 360-degree view from a site dubbed "Engineering Flats" shows the rover's shadow.

The component images for this 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 the missi...

The piece of metal with the American flag on it in this image of a NASA rover on Mars is made of aluminum recovered from the site of the World Trade Center towers in the weeks after their destruction.

This cylindrical-perspective stereo mosaic was created from navigation camera images acquired by NASA's Mars Exploration Rover Spirit during Spirit's sol 153, on June 8, 2004. Spirit is pointing to...
