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 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...

Rover 2 is driven over staggered ramps to test the suspension's range of motion.

This image shows a portion of the rim of "Erebus Crater" in the Meridiani Planum region of Mars.

On May 19th, 2005, NASA's Mars Exploration Rover Spirit captured this stunning view as the Sun sank below the rim of Gusev crater on Mars.

The "Lion King" panorama was the largest panorama obtained by either rover in 2004.

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.

NASA's Mars Rover Opportunity catches its own late-afternoon shadow in this dramatically lit view eastward across Endeavour Crater on Mars.

This three-dimensional anaglyph stereo view was created from navigation camera frames that NASA's Mars Exploration Rover Opportunity acquired at about 4:05 p.m., local solar time on Mars, on sol 10...

These side-by-side images were taken by the Pan Camera (Pancam) on NASA's Opportunity rover. They're actually the same image; the left version is how the image originally came down, due to data dro...

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.

The flat-faced rock near the center of this image is a target for contact investigation by NASA's Mars Exploration Rover Opportunity in early March 2015.

The aeroshell protects the rover from fiery temperatures as it enters the Martian atmosphere in January, 2004.

Find out how the Mars Exploration Rover team traversed the Red Planet, examined the diverse environment and transformed our understanding of Mars.

During the three-year trek of NASA's Mars Rover Opportunity from Victoria crater to Endeavour crater, rover planners captured a horizon photograph at the end of each drive. 309 images taken during ...

This image shows NASA's Mars Exploration Rover Opportunity perched on the edge of "Concepción" crater in Meridiani Planum, Mars.

This false-color view from NASA's Mars Exploration Rover Opportunity shows "Lunokhod 2 Crater," which lies south of Solander Point on the west rim of Endeavour Crater.

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

This map show a portion of Endeavour Crater's western rim that includes the "Marathon Valley" area investigated intensively by NASA's Mars Exploration Rover Opportunity in 2015 and 2016, and a flu...

This stereo view from the navigation camera on NASA's Mars Exploration Rover Opportunity shows a vista across Endeavour Crater, with the rover's own shadow in the foreground. The view spans 216 com...
