Replicating Martian Dunes

NASA's Mars rover Curiosity carries five cylindrical blocks of organic check material for use in a control experiment if the rover's Sample Analysis at Mars (SAM) laboratory detects any organic com...

NASA's Curiosity heads to rock target "Jake," named in honor of Mars Science Laboratory engineer Jacob Matijevic.

NASA’s Curiosity Mars rover used its black-and-white navigation cameras to capture panoramas of this scene at two times of day. Blue, orange, and green color was added to a combination of both pano...

Patches of Martian sandstone visible in the lower-left and upper portions of this view from the Mast Camera (Mastcam) of NASA's Curiosity Mars rover have a knobbly texture due to nodules apparently...

The Sample Analysis at Mars instrument suite will weigh about 83 pounds (38 kilograms) and make up about half the science payload of the Mars Science Laboratory mission. It is a suite of three inst...

This set of images shows the movement of the rear right wheel of NASA's Curiosity as rover drivers turned the wheels in place at the landing site on Mars.

Engineers use the Scarecrow rover to test driving on different types of terrain. In this image, the rover was taken out to the Dumont Dunes in California's Mojave Desert, near Death Valley for tes...

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.

ASA's Curiosity Mars rover used the Navigation Camera (Navcam) on its mast to catch this look-back eastward at wheel tracks from driving through and past "Dingo Gap" inside Gale Crater.

This pair of graphs shows about one-fourth of a Martian year's record of temperatures (in degrees Celsius) measured by the Rover Environmental Monitoring Station (REMS) on NASA's Curiosity rover.

This map shows the route on lower Mount Sharp that NASA's Curiosity followed in April and early May 2015, in the context of the surrounding terrain. Numbers along the route identify the sol, or Ma...

The team operating NASA's Curiosity Mars rover is developing techniques that the rover might be able to use to resume drilling into rocks on Mars. In this June 2017 photo, JPL robotics engineer Vla...

This image shows the location of the 150-micrometer sieve screen on NASA's Mars rover Curiosity, a device used to remove larger particles from samples before delivery to science instruments.

In the Payload Hazardous Servicing Facility at NASA's Kennedy Space Center in Florida, the fairing acoustic protection (FAP) system lining the inside of the Atlas V payload fairing for NASA's Mars ...

This image, taken with the High Resolution Imaging Science Experiment (HiRISE) camera, shows the transition between the "Murray Formation," in which layers are poorly expressed and difficult to tra...

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.

A New Perspective on Murray Ridge

NASA's Mars rover Curiosity drilled into this rock target, "Cumberland," during the 279th Martian day, or sol, of the rover's work on Mars (May 19, 2013) and collected a powdered sample of material...

This portion of a color mosaic taken by NASA's Mars Curiosity rover shows strata exposed along the margins of the valleys in the "Pahrump Hills" region on Mars.

A screen capture from NASA's new Experience Curiosity website shows the rover in the process of taking its own self-portrait.

This view combines several frames taken by the Mast Camera (Mastcam) on NASA's Mars rover Curiosity, looking into a valley to the west from the eastern side of a dune at the eastern end of the valley.

This image from the Chemistry and Camera (ChemCam) instrument on NASA's Curiosity Mars rover shows detailed texture of a rock target called "Elk" on Mars' Mount Sharp, revealing laminations that ar...

This view from the Mast Camera (Mastcam) on NASA's Curiosity Mars rover shows a site with a network of prominent mineral veins below a cap rock ridge on lower 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...

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 ...
