Researchers used the panoramic camera (Pancam) on NASA's Mars Exploration Rover Opportunity to capture this view of comet C/2013 A1 Siding Spring as it passed near Mars on Oct. 19, 2014.

"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.

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 false-color panoramic image, taken on martian day, or sol, 561 (Aug. 22, 2005) by the Opportunity rover, shows the nature of the outcrop rocks that the rover is encountering on its southward j...

This image shows segments of the western rim of Mars' Endeavour Crater. NASA's Mars rover Opportunity has explored parts of the rim since 2011. The view covers an area about 9 miles wide. It was ta...

This synthetic image of NASA's Opportunity Mars Exploration Rover inside Endurance Crater was produced using "Virtual Presence in Space" technology.

This image taken at Meridiani Planum, Mars, by the panoramic camera on the Mars Exploration Rover Opportunity shows the rover's Moessbauer spectrometer (circular device in center), located on its i...

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.

This view captured by Spirit called "Legacy" panorama, combines images taken between the landing site and the rim of "Bonnevile Crater."

These images of a sand "ripple" were acquired by Opportunity using its panoramic camera on sol 644 and its navigation camera on sol 645.

With a model of NASA's Opportunity rover behind him, John Callas, project manager of the Spirit and Opportunity Mars rovers, speaks about the rovers' achievements at the agency's Jet Propulsion Lab...

A grooved ridge called "Rocheport" on the rim of Mars' Endeavour Crater spans this stereo scene from NASA's Mars rover Opportunity. The view combines images from left eye and right eye of the rover...

With the parachute deployed, three retrorockets fire their engines, suspending the lander 30 - 50 feet above the Martian surface.

This full-circle scene combines 817 images taken by the panoramic camera (Pancam) on Opportunity.

This cylindrical-perspective stereo mosaic was created from navigation camera images acquired by NASA's Mars Exploration Rover Spirit during Spirit's sol 153, on June 8, 2004. Spirit is pointing to...

The rock abrasion tool on NASA's Mars Exploration Rover Spirit ground two holes in a relatively soft rock called "Wooly Patch" near the base of the "Columbia Hills" inside Gusev Crater on Mars.

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

This full-circle, stereo panorama shows the terrain around the NASA Mars Exploration Rover Opportunity during the 3,071st Martian day, or sol, of the rover's work on Mars (Sept. 13, 2012).

This oblique view with moderate vertical exaggeration shows the portion of the rim of Endeavour crater given the informal name "Spirit Point." This is the location where the team operating NASA's ...

The color image on the left was 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 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...

Cindy Oda stood up to share her experience working with NASA’s Opportunity rover during a team meeting in Mission Control at NASA’s Jet Propulsion Laboratory in Pasadena, California.

This plot shows how planetary geologists are narrowing in on the composition of a rock target on Mars, known as "Esperance," located in a fracture that cuts through the Matijevic formation on the "...

This view of a rock called "Block Island," the largest meteorite yet found on Mars, comes from the panoramic camera (Pancam) on NASA's Mars Exploration Rover Opportunity.

This map updates progress that NASA's Mars Exploration Rover Opportunity is making toward reaching a driving distance equivalent to a marathon footrace. It indicates the rover position on March 5, ...
