Details of the Gusev Crater designated landing site are added with topographic information and higher-resolution imaging from instruments on the Mars Global Surveyor and Mars Odyssey orbiters.

A self-portrait of NASA's Mars Exploration Rover Opportunity taken by the rover's panoramic camera (Pancam) shows effects of recent winds removing much of the dust from the solar arrays.

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

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

This artist's rendering depicts NASA's Mars Exploration Rovers, Spirit and Opportunity. The twin rovers were launched in 2003 and arrived on Mars in January 2004.

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...

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...

These two thumbnail images, with the ghostly dot of a faint Sun near the middle of each, are the last images NASA's Opportunity rover took on Mars.

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...

This self-portrait of NASA's Mars Exploration Rover Opportunity comes courtesy of the Sun and the rover's front hazard-avoidance camera.

NASA's Mars Exploration Rover Opportunity used its navigation camera (Navcam) to record this image of the northern end of "Solander Point," a raised section of the western rim of Endeavour Crater.

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

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's position on March 2...

Scientists and engineers working on NASA’s Mars Exploration Rover mission gather for a team portrait during the rovers’ prime mission on Mars in 2004 at NASA’s Jet Propulsion Laboratory in Pasadena...

Engineers for NASA's Mars Exploration Rover Mission are completing assembly and testing for the twin robotic geologists at JPL. This

This is the 3-D anaglyph showing a microscopic image taken of soil featuring round, blueberry-shaped rock formations on the crater floor at Meridiani Planum, Mars. This image was taken on the 13th ...

So, you want to study Mars with a lander or rover - but where exactly do you send it? Learn how scientists and engineers tackle this question in this 60-second video from NASA's Jet Propulsion Labo...

This 360-degree stereo anaglyph of the terrain surrounding NASA's Mars Exploration Rover Opportunity was taken on the rover's 171st sol on Mars (July 17, 2004).

This image superimposes an artist's concept of the Mars Exploration Rover Opportunity on the rim of Victoria Crater. It is done to give a sense of scale.

This late-afternoon view from the front Hazard Avoidance Camera on NASA's Mars Exploration Rover Opportunity shows a pattern of rock stripes on the ground, a surprise to scientists on the rover tea...

Opportunity's wheels dug more than 10 centimeters (4 inches) deep into the soft, sandy material of a wind-shaped ripple in Mars' Meridiani Planum region during the rover's 446th martian day, or sol...

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...

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...
