In the Payload Hazardous Servicing Facility, workers prepare to lift the Mars Exploration Rover-1 (MER-B) onto a spin table during preflight processing of the spacecraft.

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.

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.

The Pancam on NASA's Opportunity Mars rover imaged this small, relatively fresh crater in April 2017, during the 45th anniversary of the Apollo 16 mission to the moon. The rover team chose to call ...

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

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...

This image from the panoramic camera (Pancam) on NASA's Mars Exploration Rover Opportunity shows where a rock called "Pinnacle Island" had been before it appeared in front of the rover in early Jan...

During four months prior to the fourth anniversary of its landing on Mars, Opportunity examined rocks inside an alcove called "Duck Bay" in the western portion of Victoria Crater.

A dance-step pattern is visible in the wheel tracks near the left edge of this scene recorded in stereo by the navigation camera on NASA's Mars Exploration Rover Opportunity during the 2,554th Mart...

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...
