Mars Exploration Rover Fact Sheet

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...

Opportunity used its panoramic camera to take the images combined into this mosaic view of the rover.

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, ...

This image from the front hazard-avoidance camera (Hazcam) on the NASA Mars Exploration Rover Opportunity shows the rover's arm extended for examination of a target called "Onaping" at the base of ...

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 "...

This 180-degree mosaic of images from the navigation camera on the NASA Mars Exploration Rover Opportunity shows terrain near the rover during the 3,153rd Martian day, or sol, of the rover's work o...

This image from NASA's 2001 Mars Odyssey spacecraft shows part of the margin of the north polar cap and the surrounding plains. The layering of the ice is easily visible due to the dust that is dep...

NASA's Mars Exploration Rover Opportunity has been on the western rim of Endeavour Crater in Meridiani Planum for about two years.

This image from NASA's Mars Odyssey shows a crater from a double impact - two meteors hitting simultaneously. The two meteors would have started as a single object and, at some point prior to impac...

"Yogi" is a meter-size rock about 5 meters northwest of the Mars Pathfinder lander and was the second rock visited by the Sojourner Rover's alpha proton X-ray spectrometer (APXS) instrument. This v...

This crater has gullies on its southwest-facing walls and rim, as well as and what appears to be two separate instances of lobate (ear-shaped) material associated to its interior gullies.

This June 2017 view from the Pancam on NASA's Opportunity Mars rover shows the area just above "Perseverance Valley" on the western rim of Endeavour Crater. Color has been enhanced to make diffe...

This anaglyph, acquired by NASA's Phoenix Lander's Surface Stereo Imager on Sol 33, the 33rd Martian day of the mission (June 28, 2008), shows a stereoscopic 3D view of the Martian surface near the...

This series of images shows carbon dioxide ice sublimating (going directly from a solid to a gas) inside a pit at Mars' south pole. Each frame of the animation was taken by the HiRISE camera on NAS...

NASA's Mars Exploration Rover Opportunity obtained this view from the top of the "Cape Tribulation" segment of the rim of Endeavour Crater. The rover reached this point three weeks before the 11th ...

Members of the NASA Mars Helicopter team inspect the flight model (the actual vehicle going to the Red Planet), inside the Space Simulator.

Meet some of the women team members and hear about the exciting and challenging jobs they do in science and engineering while working with Mars rover Curiosity.

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...

Two generations of Rovers.

In this image, engineers test cameras on the top of the mast and front chassis of NASA's Perseverance Mars rover. The image was taken on July 23, 2019, at NASA's Jet Propulsion Laboratory in Southe...

NASA's Mars Exploration Rover Opportunity used its panoramic camera (Pancam) to capture this false-color panorama of the "Matijevic Hill" area on the "Cape York" segment of the western rim of Endea...

Two images from the Mast Camera (Mastcam) on NASA's Curiosity rover depicting the change in the color of light illuminating the Martian surface since a dust storm engulfed Gale Crater. The left ima...

This HiRISE image shows a mixture of bright and dark units. The bright units have a mineral called sulfate (salty sulfuric acid) that on Earth typically forms in the presence of water as an evapori...

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.
