Some of the team members from NASA's Mars Exploration Rover project were still in college -- or even high school -- when the rovers landed in 2004. Hear their stories of becoming part of this remar...

This image from the panoramic camera (Pancam) on NASA's Mars Exploration Rover Opportunity shows where a rock called "Pinnacle Island" had been before it appeared in front of the rover in early Jan...

The enhanced-color image taken by the microscopic imager on the Mars Exploration Rover Spirit shows the rock dubbed "Mazatzal" after a portion of its surface was brushed clean by the rover's rock a...

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).

The target beneath the tool turret at the end of the rover's robotic arm in this image from NASA's Mars Exploration Rover Opportunity is "Private John Potts." It lies high on the southern side of "...

Protected by large airbags, the lander falls away from the parachute, landing safely on Mars.

While driving eastward toward the northwestern flank of "McCool Hill," Spirit's wheels churned up the largest amount of bright soil discovered so far in the mission.

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.

This image shows the Spirit rover's landing site, the Columbia Memorial Station, at Gusev Crater, Mars.

The flat-faced rock near the center of this image is a target for contact investigation by NASA's Mars Exploration Rover Opportunity in early March 2015.

Researchers used the panoramic camera (Pancam) on NASA's Mars Exploration Rover Opportunity to capture this 10-second-exposure view of comet C/2013 A1 Siding Spring as it passed near Mars on Oct. 1...

NASA's Mars Exploration Rover Opportunity observed this outcrop on the "Murray Ridge" portion of the rim of Endeavour Crater as the rover approached the 10th anniversary of its landing on Mars.

This stereo view was taken by the panoramic camera on NASA's Mars Exploration Rover Spirit on the rover's 87th martian day, or sol (April 1, 2004), just after Spirit left "Bonneville Crater." It sh...

The left 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.

In the fourth season of “On a Mission” we’ll be transported to the Red Planet with all five of NASA’s Mars rovers.

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

Mars Exploration Rover parachute deployment testing

A "Martian mechanic" checks beneath the completely deployed Rover 1 lander. Atop the lander is Rover 1 with its wheels and solar arrays in the stowed position.

In this season 4 finale, Gentry Lee and Rob Manning reveal how surprises, hidden flaws, and uncertainties have always been a part of rovers and the exploration of Mars.

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

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 ...
