NASA's Mars Exploration Rover Spirit has been making tracks on Mars for seven months now, well beyond its original 90-day mission. The rover traveled more than 3 kilometers (2 miles) to reach the "...

At a rock called "Clovis," the rock abrasion tool on Spirit cut a 9-millimeter (0.35-inch) hole. To the right of the drill hole is a "brush flower" of circles produced by scrubbing the surface of...

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

Late on Feb. 12, 2019, mission controllers at NASA’s Jet Propulsion Laboratory in Pasadena, California, sent the last commands to ask NASA’s Opportunity rover on Mars to call home. 

Taken on June 10, 2018 (the 5,111th Martian day, or sol, of the mission) this “noisy,” incomplete image was the last data NASA's Opportunity rover sent back from Perseverance Valley on Mars. 

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.

"Marathon Valley" on Mars opens northeastward in this stereo version of a scene from the Pancam of NASA's Mars Exploration Rover Opportunity. The scene, recorded in April and May 2016, appears thre...

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...

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

This infographic highlights NASA’s twin robot geologists, the Mars Exploration Rovers (MER) Spirit and Opportunity.  The rovers landed on the Red Planet in 2004, in search of answers about the hist...

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...

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 view from NASA's Opportunity Mars rover shows part of "Marathon Valley," a destination on the western rim of Endeavour Crater, as seen from an overlook north of the valley. It was taken by the...

NASA's Mars Exploration Rover Opportunity recorded this view of the summit of "Cape Tribulation," on the western rim of Endeavour Crater on the day before the rover drove to the top.

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 ...

This mosaic was stitched together using images from the Navigation Camera, or Navcam, on NASA's Opportunity rover. The scene shows the rover's tracks made in Perseverance Valley between Sols 5,000 ...

This full-circle, stereo panorama shows the terrain around the NASA Mars Exploration Rover Opportunity during the 3,105th Martian day, or sol, of the rover's work on Mars (Oct. 18, 2012).
