The boulder-studded ridge in this scene recorded by NASA's Mars Exploration Rover Opportunity is "McClure-Beverlin Escarpment," informally named for Jack Beverlin and Bill McClure, engineers who on...

Even after the landers and airbags safely bounce to a complete stop on Mars, the challenges of getting to Mars continue. It will take each rover a minimum of nine days to emerge from its lander coc...

A portion of an exposure of bedrock dubbed "Larry's Outcrop" shows little layering in this view, in contrast to nearby outcrops called "Methuselah" and "Jibsheet."

This synthetic image of the Spirit Mars Exploration Rover in the "Columbia Hills" was produced using "Virtual Presence in Space" technology.

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

Results from Opportunity and Curiosity show Mars could have supported life.

This Martian scene shows contrasting textures and colors of "Hinners Point," at the northern edge of "Marathon Valley," and swirling reddish zones on the valley floor to the left.

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.

This image from the Mars Exploration Rover Opportunity's panoramic camera is an approximate true-color rendering of the exceptional rock called "Berry Bowl" in the "Eagle Crater" outcrop.

During a team meeting for NASA’s Opportunity rover, Ben Cark of the Space Science Institute talks about his experiences working on NASA’s longest-lived Mars surface explorer. 

NASA's Mars Exploration Rover 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 (Oct. 31, 2010).

This scene from the panoramic camera (Pancam) on NASA's Mars Exploration Rover Opportunity catches "Pillinger Point," on the western rim of Endeavour Crater, in the foreground. The eastern rim of t...

Bekah Sosland was an eighth-grade student in Fredericksburg, Texas, when NASA's Mars Exploration Rovers Spirit and Opportunity landed on Mars in January 2004.

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.

"Marathon Valley" on Mars opens to a view across Endeavour Crater in this scene from the Pancam of NASA's Mars rover Opportunity. The scene merges many exposures taken during April and May 2016. Th...

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 Martian scene shows contrasting textures and colors of "Hinners Point," at the northern edge of "Marathon Valley," and swirling reddish zones on the valley floor to the left.

Two spacecraft engineers join a grouping of vehicles providing a comparison of three generations of Mars rovers developed at NASA's Jet Propulsion Laboratory, Pasadena, Calif. The setting is JPL's ...

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

An artist's concept portrays a NASA Mars Exploration Rover on the surface of 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.

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.

This two-image blink shows a comparison of two exposure times in images from the panoramic camera (Pancam) on NASA's Mars Exploration Rover Opportunity showing comet C/2013 A1 Siding Spring as it f...
