Scarecrow Rover Wheel Closeup

NASA's Mars Exploration Rover Opportunity used its navigation camera to take the exposures combined into this stereo view of a wee crater, informally named "Skylab," along the rover's route. The co...

This image taken by the Mars Hand Lens Imager (MAHLI) on NASA's Mars rover Curiosity shows the texture of the patch of flat-lying bedrock called "Cumberland," which was the mission's second target ...

NASA's Mars rovers keep getting bigger. This photo provides a comparison of the wheel sizes for three generations of them.

This right-eye member of a stereo pair of images from the Navigation Camera (Navcam) on NASA's Curiosity Mars rover shows a full 360-degree view of the rover's surroundings at the site where it fir...

Testing of the cruise stage for NASA's Mars Science Laboratory in August 2010 included a session in a facility that simulates the environment found in interplanetary space.

As part of a multi-mission campaign, NASA's Curiosity rover is observing Martian moon transits, the first of which involved the moon Phobos grazing the sun's disk.

This artists concept of MSL is a still from the MSL Mission Overview video demonstrating the ChemCam instrument.

The yellow triangles on this graph indicate concentrations of the elements titanium and silicon in selected rock targets with high silica content analyzed by the Alpha Particle X-ray Spectrometer (...

This side-by-side comparison shows the X-ray diffraction patterns of two different samples collected from the Martian surface by NASA's Curiosity rover.

This image shows the target landing area for Curiosity, the rover of NASA's Mars Science Laboratory mission.

Thick stacks of clay minerals indicate chemical alteration of thick stacks of rock by interaction with liquid water on ancient Mars.

An analysis of a drilled rock sample from NASA's Curiosity rover shows the presence of water, carbon dioxide, oxygen, sulfur dioxide, and hydrogen sulfide released on heating. The results analyzing...

Examination of a calcium sulfate vein called "Diyogha" by the ChemCam instrument on NASA's Curiosity Mars rover found boron, sodium and chlorine. An image from the rover's Mastcam, at left, provide...

The Mastcam on NASA's Curiosity Mars rover captured this view of "Vera Rubin Ridge" about two weeks before the rover starting to ascend this steep ridge on lower Mount Sharp.

Five years of images from the front left hazard avoidance camera (Hazcam) on NASA's Curiosity Mars rover were used to create this time-lapse movie. The inset map shows the rover's location in Mars'...

This self-portrait of NASA's Mars rover Curiosity combines dozens of exposures taken by the rover's Mars Hand Lens Imager (MAHLI) during the 177th Martian day, or sol, of Curiosity's work on Mars (...

Half of the Atlas V payload fairing for NASA's Mars Science Laboratory (MSL) mission is lifted into a vertical position in the airlock of the Payload Hazardous Servicing Facility at NASA's Kennedy ...

This stereo view from NASA's Mars rover Curiosity shows a rock called "Link," which bears rounded pebbles that provide evidence about vigorous flow of water in a stream on ancient Mars.

This is the first 360-degree panorama in color of the Gale Crater landing site taken by NASA's Curiosity rover. The panorama was made from thumbnail versions of images taken by the Mast Camera.

This stereo landscape scene from NASA's Curiosity Mars rover shows rows of rocks in the foreground and Mount Sharp on the horizon. It appears three dimensional when viewed through red-blue glasses ...

This image from the Mast Camera (Mastcam) on NASA's Mars rover Curiosity shows inclined layering known as cross-bedding in an outcrop called "Shaler" on a scale of a few tenths of meters, or decime...

This graphic shows the locations of the cameras on NASA's Curiosity rover.

This image is the first high-resolution color mosaic from NASA's Curiosity rover, showing the geological environment around the rover's landing site in Gale Crater on Mars.

Engineers and technicians have been planning for months and working for weeks on the big move for NASA's Mars Curiosity rover.
