6th Year Anniversary Graphic

A lunar eclipse, a solar eclipse and Mars has a close encounter with a comet.

This beautiful scene reveals a tremendous amount of detail in Spirit's surroundings at a place called "Winter Haven," where the rover spent many months parked on a north-facing slope in order to ke...

This panoramic image, dubbed "Rub al Khali," was taken by Opportunity on the plains of Meridiani during the rover's 456th to 464th sols on Mars.

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...

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.

This blink comparison aids evaluation of a drive by NASA's Mars Exploration Rover Spirit during the rover's 2,099th Martian day, or sol (Nov. 28, 2009).

NASA's Mars Exploration Rover Opportunity has been on the western rim of Endeavour Crater in Meridiani Planum for about two years.

NASA's Mars Exploration Rover Opportunity drove about 12 feet (3.67 meters) on May 8, 2012, after spending 19 weeks working in one place while solar power was too low for driving during the Martian...

Faire atterrir une sonde sur Mars est l’une des choses les plus complexes à réaliser. Cette vidéo de 60 secondes explique comment cela est possible, et illustre les trois systèmes d'atterrissage ut...

Using footage filmed at JPL when Spirit touched down on Jan. 3, 2004, as well an animation depicting the rover's arrival at the Red Planet, this video celebrates the 20th anniversary of Mars Explor...

After bouncing to a stop, the lander's petals unfold and the Mars Exploration Rover drives onto the surface of Mars.

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

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...

The "Columbia Hills" flank Spirit's path in this view.

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...

This image shows stone stripes on the side of a volcanic cone on Mauna Kea, Hawaii. The stripes are made of small rock fragments and they are aligned downhill as freeze-thaw cycles have lifted them...

"Perseverance Valley" lies just on the other side of the dip in the crater rim visible in this view from the Navigation Camera (Navcam) on NASA's long-lived Mars Exploration Rover Opportunity, whic...

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.

This synthetic image of the Spirit Mars Exploration Rover in the "Columbia Hills" was produced using "Virtual Presence in Space" technology.

The cruise stage provides power, communication and propulsion for the rover and lander within its cocoon made up of the heatshield and backshell for the cruise to Mars.

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

This image highlights the bumpy terrain surrounding the rover.

As NASA's Mars Exploration Rover Opportunity neared the ninth anniversary of its landing on Mars, the rover was working in the 'Matijevic Hill' area seen in this stereo view from Opportunity's pano...

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...
