6th Year Anniversary Graphic

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

NASA's Mars Exploration Rover Opportunity used its navigation camera to record this view at the end of a 111-meter (364-foot) drive on the 2,353rd Martian day, or sol, of the rover's mission on Mar...

This scene 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 section from a panorama that NASA's Mars Exploration Rover Spirit acquired in October 2005 from the top of "Husband Hill" presents the view toward the south from that summit.

This 360-degree stereo anaglyph of the terrain surrounding NASA's Mars Exploration Rover Opportunity was taken on the rover's 171st sol on Mars (July 17, 2004).

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...

This graphic shows the ongoing contributions of NASA’s rovers and orbiters during a Martian dust storm that began on May 30, 2018.

In this navigation camera raw image, NASA's Opportunity Rover looks back over its own tracks on Aug. 4, 2010. NASA's Jet Propulsion Laboratory, a division of Caltech in Pasadena, manages the Mars E...

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

This enhanced-color view from within "Perseverance Valley," on the inner slope of the western rim of Mars' Endurance Crater, includes wheel tracks from the Opportunity rover's descent of the valley...

In this selfie, Spirit shows her solar panels gleaming in the Martian sunlight and carrying only a thin veneer of dust two years after the rover landed and began exploring the red planet.

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...

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...

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.

This is the 3-D anaglyph showing a microscopic image taken of soil featuring round, blueberry-shaped rock formations on the crater floor at Meridiani Planum, Mars. This image was taken on the 13th ...

Gazing across the landscape of the "Columbia Hills" in Gusev Crater on Mars, scientists saw hints of tilted rock layers across the area traversed by the Spirit rover.

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...

This synthetic image of NASA's Opportunity Mars Exploration Rover inside Endurance Crater was produced using "Virtual Presence in Space" technology.

The circular shapes seen on the martian surface in these images are "footprints" left by Opportunity's airbags during landing as the spacecraft gently rolled to a stop.

This is the Opportunity "Erebus Rim" panorama, acquired on sols 652 to 663 (Nov. 23 to Dec. 5, 2005 ), as Opportunity was exploring sand dunes and outcrop rocks in Meridiani Planum.

Mars Exploration Rover parachute deployment testing in the world's largest wind tunnel at NASA's Ames Research Center, Moffet Field, Calif.

Details of the Gusev Crater designated landing site are added with topographic information and higher-resolution imaging from instruments on the Mars Global Surveyor and Mars Odyssey orbiters.

This self-portrait of NASA's Mars Exploration Rover Opportunity comes courtesy of the Sun and the rover's front hazard-avoidance camera.

On Earth, a fast runner takes a few hours to complete a marathon. On Mars, it's taken 11 years. NASA's Opportunity rover crossed that finish line in 2015.

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...
