Mars Exploration Rover team members with rover

NASA Science missions circle Earth, the Sun, the Moon, Mars and many other destinations within our solar system, including spacecraft that look out even further into our universe. The Science Fleet...

JPLers pounded the pavement in celebration of a Mars marathon milestone. Opportunity rover took 11 years and 2 months to clock 26.2 miles. The team's time was considerably less.

This Martian scene shows contrasting textures and colors of "Hinners Point," at the northern edge of "Marathon Valley," and swirling reddish zones on the valley floor to the left.

This 360-degree stereo anaglyph of the terrain surrounding NASA's Mars Exploration Rover Spirit on the 147th martian day of the rover's mission inside Gusev Crater, on June 1, 2004, was assembled f...

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...

A grooved ridge called "Rocheport" on the rim of Mars' Endeavour Crater spans this scene from the Pancam on NASA's Mars rover Opportunity. The view extends from south-southeast on the left to north...

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...

Protected by large airbags, the lander falls away from the parachute, landing safely on Mars.

Stowed in the nose cone of this Delta II rocket, the Mars Exploration Rover blasts off from the Kennedy Space Center in Florida. It's destination: the planet Mars.

A section of the Mars Science Laboratory's Gale Crater landing site is shown, with a representative path from the landing location toward the layered mound to the south.

This bird's-eye view combines a self-portrait of the spacecraft deck and a panoramic mosaic of the Martian surface as viewed by the Spirit rover.

Divide and conquer: combining 11 small sections of "Block Island" (the color map shows five of the sections).

This 3-D cylindrical-perspective projection was constructed from a sequence of four images taken by the navigation camera onboard the Mars Exploration Rover Opportunity. The images were acquired...

One of two Mars Exploration Rovers sits inside its cruise stage waitingto undergo environmental testing at NASA's Jet PropulsionLaboratory.

Born together, the Spirit and Opportunity twin rovers followed divergent paths after they landed on opposite sides of Mars. Opportunity’s journey was marked by good fortune, while Spirit’s was trou...

Cumulative driving by NASA's Mars Exploration Rover Opportunity surpassed marathon distance on March 24, 2015, as the rover neared a destination called "Marathon Valley," which is middle ground of ...

NASA Associate Administrator for Science Thomas Zurbuchen addressed the Opportunity rover team inside Mission Control at NASA’s Jet Propulsion Laboratory in Pasadena, California, a few hours before...

This image from Opportunity's panoramic camera features the remains of the heat shield that protected the rover from temperatures of up to 2,000 degrees Fahrenheit as it made its way through the ma...

The High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter acquired this image of the Opportunity rover on the southwest rim of "Santa Maria" crater on New...

Opportunity captured this vista of "Victoria Crater" from the viewpoint of "Cape Verde," one of the promontories that are part of the scalloped rim of the crater.

Researchers used the panoramic camera (Pancam) on NASA's Mars Exploration Rover Opportunity to capture this view of comet C/2013 A1 Siding Spring as it passed near Mars on Oct. 19, 2014.
