Researchers used NASA's Mars Exploration Rover Opportunity to find a water-related mineral on the ground that had been detected from orbit, and found it in the dark veneer of rocks on the rim of En...

This is a zoomed in view on Spirit 's "Lookout" panorama on the drive up to the summit "Husband Hills."

NASA’s Curiosity Mars rover set out to answer a big question when it landed on the Red Planet 10 years ago: Could Mars have supported ancient life? Scientists have discovered the answer is yes and ...

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

NASA's Mars Exploration Rover Opportunity captured this stereo view after beginning to ascend the northwestern slope of "Solander Point" on the western rim of Endeavour Crater.

Members of the Mars Exploration Rover Mission's Entry, Descent and Landing team rejoice at the news that mission control received its first signal from Spirit, indicating the rove...

NASA's Mars Exploration Rover Opportunity used its navigation camera to capture the component images for this stereo, 360-degree panorama near the ridgeline of Endeavour Crater's western rim. The v...

This 360-degree view, called the "McMurdo" panorama, comes from the panoramic camera (Pancam) on NASA's Mars Exploration Rover Spirit. From April through October 2006, Spirit has stayed on a small ...

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 image shows an extreme close-up of round, blueberry-shaped formations in the martian soil near a part of the rock outcrop at Meridiani Planum called Stone Mountain

This view taken by Spirit show's the "Columbia Hills" up ahead.

This image from the Mars Exploration Rover Spirit's rear hazard identification camera shows the rover's hind view of the lander platform, its nest for the past 12 sols, or martian days. The rover i...

Kris Capraro adds the finishing touches of realistic color to the model meteorite.

A grooved ridge called "Rocheport" on the rim of Mars' Endeavour Crater spans this scene from the Pancam on NASA's Mars rover Opportunity. This version of the scene is presented in enhanced color t...

In late November 2005 while descending "Husband Hill," Spirit took the most detailed panorama so far of the "Inner Basin," one of the rover's target destination.

Dr. Ed Weiler, associate administrator, Office of Space Science, NASA Headquarters and Mars Exploration Program manager, Dr. Firouz Naderi (right) are delighted with the news of Opportunity's safe...

This stunning image features the heat shield impact site of NASA's Mars Exploration Rover Opportunity.

This global map of Mars shows a growing dust storm as of June 6, 2018. The map was produced by the Mars Color Imager (MARCI) camera on NASA's Mars Reconnaissance Orbiter spacecraft.

This view from NASA's Opportunity Mars rover shows part of "Marathon Valley" as seen from an overlook north of the valley. It was taken by the rover's Pancam on March 13, 2015. This version is pres...

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...

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. 

This enhanced-color view of ground sloping downward to the right in "Perseverance Valley" shows textures that may be due to abrasion by wind-driven sand. The Pancam on NASA's Mars rover Opportunity...

This graph compares the elemental composition of typical soils at three landing regions on Mars.

The designated landing site for the second Mars Exploration Rover mission is Meridiani Planum, seen here in its geological context from NASA Viking images.
