A crowd of excited men and women who work on the Mars Exploration Rover mission are wearing white paper 3-D glasses with red and blue lenses to view some of the Spirit rover's first three-dimension...

NASA's twin robot geologists, the Mars Exploration Rovers, will launch toward Mars in 2003 in search of answers about the history of water on Mars.

This animation features the Mars Exploration Rover's entry into the martian atmosphere and final soft landing using airbags. (Audio: mechanical sounds only)

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.

The Mars Exploration Rover-2 is moved to a workstand in the Payload Hazardous Servicing Facility.

NASA's twin robot geologists, the Mars Exploration Rovers, will launch toward Mars in 2003 in search of answers about the history of water on Mars. The rovers will be targeted to sites that appear ...

NASA's Opportunity Mars rover, working on Mars since January 2004, passed marathon distance in total driving on March 24, 2015. This map shows the rover's entire traverse from landing to that point.

In the Payload Hazardous Servicing Facility, an overhead crane lowers the Mars Exploration Rover (MER) aeroshell toward a rotation stand.

NASA's Mars Exploration Rover Opportunity recorded this view just after reaching the summit of "Cape Tribulation," on the western rim of Endeavour Crater, on Jan. 6, 2015, the 3,894th Martian day, ...

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

Opportunity used its panoramic camera to record this eastward horizon view on the 2,407th Martian day, or sol, of the rover's work on Mars (October 31, 2010).

This self-portrait from Opportunity shows dust accumulation on the rover's solar panels as the mission approached its fifth Martian winter.

"Intrepid" crater on Mars carries the name of the lunar module of NASA's Apollo 12 mission, which landed on Earth's moon Nov. 19, 1969.

In February 2015, NASA's Mars Exploration Rover Opportunity is approaching a cumulative driving distance on Mars equal to the length of a marathon race. This map shows the rover's position relative...

From its perch high on a ridge, NASA's Mars Exploration Rover Opportunity recorded this image of a Martian dust devil twisting through the valley below.

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...

The component images for this stereo, 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 t...

This stereo scene from NASA's Mars Exploration Rover Opportunity shows part of "Marathon Valley," a destination on the western rim of Endeavour Crater, as seen from an overlook north of the valley.

The close camaraderie among scientists and engineers who worked on NASA’s Opportunity rover is evident in this image from Feb. 12, 2019, at NASA’s Jet Propulsion Laboratory in Pasadena, California.
