This graphic shows the geologic cross-section through lower Mount Sharp on Mars.

Processes in Mars' surface material can explain why particular xenon (Xe) and krypton (Kr) isotopes are more abundant in the Martian atmosphere than expected, as measured by NASA's Curiosity rover....

A panorama combining images from both cameras of the Mastcam on NASA's Curiosity Mars Rover shows diverse geological textures on Mount Sharp. Three years after landing on Mars, the mission is inves...

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

In the Payload Hazardous Servicing Facility at NASA's Kennedy Space Center in Florida, a technician inspects beneath NASA's Mars Science Laboratory (MSL) mission aeroshell, (containing the compact ...

This color full-resolution image showing the heat shield of NASA's Curiosity rover was obtained during descent to the surface of Mars on Aug. 5 PDT (Aug. 6 EDT).

This scene shows NASA's Curiosity Mars rover at a location called "Windjana," where the rover found rocks containing manganese-oxide minerals, which require abundant water and strongly oxidizing co...

The rock "Ithaca" shown here, with a rougher lower texture and smoother texture on top, appears to be a piece of the local sedimentary bedrock protruding from the surrounding soil in Gale Crater.

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 map shows the path on Mars of NASA's Curiosity rover toward Glenelg, an area where three terrains of scientific interest converge.

NASA's Curiosity Mars rover imaged these drifting clouds on May 17, 2019, the 2,410th Martian day, or sol, of the mission, using its Navigation Cameras (Navcams).

NASA's Curiosity Mars rover used its Navigation Camera (Navcam) to capture this view partway back down a slope it climbed toward "Marias Pass" on lower Mount Sharp. The image was taken May 22, 2015...

The network of cracks in this Martian rock slab called "Old Soaker" may have formed from the drying of a mud layer more than 3 billion years ago.

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 (...

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.

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 ...

This image from NASA's Mars Curiosity rover shows the "Amargosa Valley," on the slopes leading up to Mount Sharp on Mars.

This image from the NASA Mars Reconnaissance Orbiter shows an impact scar on Mars made by pieces of the NASA Mars Science Laboratory spacecraft that the spacecraft shed just before entering the Mar...

NASA's Mars rover Curiosity extended its robotic arm on Aug. 20, 2012, for the first time on Mars and used its Navigation Camera (Navcam) to capture this view of the extended arm.

With NASA's Mars Science Laboratory (MSL) spacecraft sealed inside its payload fairing, the United Launch Alliance Atlas V rocket rides a tall pillar of smoke and flames as it soars over Space Laun...

In this image, the Mars Science Laboratory Project Science Group, consisting of 11 men and 1 woman, are climbing up a dusty trail in New Mexico. Wearing casual hiking clothes and hats, they are cli...

In this image from NASA's Curiosity Mars rover looking up the ramp at the northeastern end of "Hidden Valley," a pale outcrop including drilling target "Bonanza King" is at the center of the scene.

This illustration portrays some of the reasons why finding organic chemicals on Mars is challenging. Whatever organic chemicals may be produced on Mars or delivered to Mars face several possible mo...

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...

This panorama from the Mast Camera (Mastcam) on NASA's Curiosity Mars rover was taken on Dec. 19 (Sol 2265). The rover's last drill location on Vera Rubin Ridge is visible, as well as the clay regi...
