Scarecrow Rover Wheel Closeup

​ NASA's Curiosity rover used an instrument called SAM (Sample Analysis at Mars) to detect seasonal changes in atmospheric methane in Gale Crater. The methane signal has been observed for nearly...

NASA's Curiosity rover captured its highest-resolution panorama of the Martian surface between Nov. 24 and Dec. 1, 2019.

After an activity called the "mini drill test" by NASA's Mars rover Curiosity, the rover's Mars Hand Lens Imager (MAHLI) camera recorded this close-up view of the results during the 180th Martian d...

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.

Modern-day Mars experiences cyclical changes in climate and, consequently, ice distribution. Unlike Earth, the obliquity (or tilt) of Mars changes substantially on timescales of hundreds of thousan...

This image is from a test series used to characterize the 100-millimeter Mast Camera on NASA's Curiosity rover. It was taken on Aug. 23, 2012, and looks south-southwest from the rover's landing site.

In this image, the scoop on NASA's Curiosity rover shows the larger soil particles that were too big to filter through a sample-processing sieve that is porous only to particles less than 0.006 inc...

This is the right-eye member of a stereo pair of images of the Mars Science Laboratory mission's rover, Curiosity.

Seasons change even on Mars and NASA's fleet of explorers are helping scientists learn more about the effects on the Red Planet.

This image shows the calibration target for the Chemistry and Camera instrument on NASA's Curiosity rover before it was installed on the rover and readied for launch.

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.

This is an artist's concept of NASA's Mars Science Laboratory spacecraft approaching Mars.

With NASA's Mars Science Laboratory (MSL) spacecraft sealed inside its payload fairing, the United Launch Alliance Atlas V rocket rides smoke and flames as it rises from the launch pad at Space Lau...

One type of feature of scientific interest on the mountain inside Gale crater is exposure of cemented fractures, evidence that groundwater once reached to at least that height of the mountain.

The graph at right presents information from the NASA Curiosity Mars rover's onboard analysis of rock powder drilled from the "Big Sky" and "Greenhorn" target locations, shown at left.

After two Martian years, Curiosity is more than a Mars geologist, scientist and explorer. It's a Mars weather reporter, too.

This heart-shaped granite rock was spotted in JPL's Mars Yard just in time for Valentine's Day. Engineers were driving the Earth-bound copy of the Curiosity rover, informally named Maggie, for tes...

This image from the Mars Hand Lens Imager (MAHLI) on NASA's Mars rover Curiosity shows details of rock texture and color in an area where the rover's Dust Removal Tool (DRT) brushed away dust that ...

Twenty-one times during the first 12 weeks that NASA's Mars rover Curiosity worked on Mars, the rover's Rover Environmental Monitoring Station (REMS) detected brief dips in air pressure that could ...

Teachers have fun putting their skills to the test in this hands-on activity during the Curiosity Educator Workshop at NASA’s Jet Propulsion Laboratory in Pasadena, Calif

"Vera Rubin Ridge," a favored destination for NASA's Curiosity Mars rover even before the rover landed in 2012, rises near the rover nearly five years later in this panorama from Curiosity's Mast C...

NASA’s Curiosity Mars rover set out to answer a big question when it landed on the Red Planet 10 years ago: Could Mars have supported ancient life? Scientists have discovered the answer is yes and ...

On the second anniversary of NASA Curiosity on Mars, the rover navigates a sandy valley on its way to Mount Sharp

This evenly layered rock photographed by the Mast Camera (Mastcam) on NASA's Curiosity Mars Rover on Aug. 7, 2014, shows a pattern typical of a lake-floor sedimentary deposit not far from where flo...
