6th Year Anniversary Graphic

NASA's Opportunity rover celebrates 8th anniversary on Mars.

NASA's Mars Exploration Rover Opportunity used its navigation camera (Navcam) to record this image of the northern end of "Solander Point," a raised section of the western rim of Endeavour Crater.

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...

Opportunity's wheels dug more than 10 centimeters (4 inches) deep into the soft, sandy material of a wind-shaped ripple in Mars' Meridiani Planum region during the rover's 446th martian day, or sol...

This is a look inside a soil trench or drift dubbed 'Serpent' after the rover successfully dug into the side of the drift.

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.

In the fourth season of “On a Mission” we’ll be transported to the Red Planet with all five of NASA’s Mars rovers.

Mars is experiencing large regional dust storms over its northern hemisphere during the past week.

This stereo view was taken by the panoramic camera on NASA's Mars Exploration Rover Spirit on the rover's 87th martian day, or sol (April 1, 2004), just after Spirit left "Bonneville Crater." It sh...

This two-image blink shows a comparison of two exposure times in images from the panoramic camera (Pancam) on NASA's Mars Exploration Rover Opportunity showing comet C/2013 A1 Siding Spring as it f...

This color image taken by the panoramic camera onboard the Mars Exploration Rover Opportunity shows the part of the rock outcrop dubbed Stone Mountain at Meridiani Planum, Mars.

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 ...

An oblique, northward-looking view based on stereo orbital imaging, shows the location of Opportunity on its journey from Cape York to Solander Point when HiRISE took the new color image.

These two images from 10 days apart show that dust was removed from the panoramic camera's calibration target on NASA's Mars Exploration Rover Spirit.

This Sept. 21, 2016, scene from the panoramic camera (Pancam) on NASA's Mars Exploration Rover Opportunity shows "Spirit Mound" overlooking the floor of Endeavour Crater. The mound stands near the ...

Opportunity used its panoramic camera to take the images combined into this mosaic view of the rover.

NASA's Mars Exploration Rover Spirit took this image of the region near "Husband Hill."

Technicians maneuver the aeroshell for Mars Exploration Rover 2 onto a workstand in the Payload Hazardous Servicing Facility.

Spirit used its microscopic imager to capture these spectacular, jagged mini-landscape on a rock called "GongGong." Wind has deposited sand and dust in the holes and crevices of the rock.

A shadow and tracks of NASA's Mars rover Opportunity appear in this March 22, 2016, image, which has been rotated 13.5 degrees to adjust for the tilt of the rover. The hillside descends to the left...

This photo shows fifteen of the women engineers and scientists who work on the Mars Exploration Rover. They are standing behind or kneeling beside a precise replica of the rover in the mission cont...

See how the scientists and engineers on Earth stretch their imaginations to design the best rover system to deal with the unpredictable dangerous terrain on Mars. Rover team members at Jet Propulsi...

Episode one launches with Jennifer Trosper in the driver’s seat. As she looks in the rearview mirror at twenty-five years of exploring with NASA’s Mars rovers, she reveals how their progression has...

These small spherules on the Martian surface are near Fram Crater, visited by NASA's Mars Exploration Rover Opportunity during April 2004. The area shown is 1.2 inches (3 centimeters) across. The v...

This stereo scene from NASA's Mars Exploration Rover Opportunity shows part of "Marathon Valley," a destination on the western rim of Endeavour Crater, as seen from an overlook north of the valley.
