Replicating Martian Dunes

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 ...

This mosaic of images from the Mast Camera (Mastcam) instrument on NASA's Curiosity Mars rover shows a series of sedimentary deposits in the Glenelg area of Gale Crater, from a perspective in Yello...

A grid of small polygons on the Martian rock surface near the right edge of this view may have originated as cracks in drying mud more than 3 billion years ago. Multiple Dec. 20, 2016, images from ...

The gray area in the center of this image is where the Dust Removal Tool on the robotic arm of NASA's Mars rover Curiosity brushed a rock target called "Wernecke."

This map shows the route driven by NASA's Mars rover Curiosity through the 43rd Martian day, or sol, of the rover's mission on Mars (Sept. 19, 2012).

This mosaic of images shows a boulder-sized rock called "Strathdon," which is made up of many complex layers. NASA's Curiosity Mars rover took these images using its Mast Camera, or Mastcam, on Jul...

The heat shield for NASA's Mars Science Laboratory is the largest ever built for a planetary mission.

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

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

This series of images shows the shadow of Phobos as it sweeps over NASA's Curiosity Mars rover and darkens the sunlight on Monday, March 25, 2019 (Sol 2358).

The percussion drill in the turret of tools at the end of the robotic arm of NASA's Mars rover Curiosity has been positioned in contact with the rock surface in this image from the rover's front Ha...

This mosaic of nine images, taken by the Mars Hand Lens Imager (MAHLI) camera on NASA's Mars rover Curiosity, shows detailed texture in a conglomerate rock bearing small pebbles and sand-size parti...

This animation demonstrates the salty ponds and streams that scientists think may have been left behind as Gale Crater dried out over time. The bottom of the image is the floor of Gale Crater, with...

This color-enhanced view of NASA's Curiosity rover on the surface of Mars was taken by the High Resolution Imaging Science Experiment (HiRISE) on NASA's Mars Reconnaissance Orbiter as the satellite...

Mars Rover Photosynth

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...

NASA's Curiosity Mars rover used its Navigation Camera to capture this view on April 11, 2015, during passage through a valley called "Artist's Drive" on the route up Mount Sharp.

This self-portrait of NASA's Mars rover Curiosity combines 66 exposures taken by the rover's Mars Hand Lens Imager (MAHLI) during the 177th Martian day, or sol, of Curiosity's work on Mars (Feb. 3...

This close-up view shows the rover Curiosity's parachute and back shell strewn across the surface of Mars.

This image from NASA's Curiosity Mars rover reveals details of a bedrock discoloration pattern at a site between "Marias Pass" and "Bridger Basin." The discoloration is not associated with individu...

This version of a self-portrait of NASA's Curiosity Mars rover at a drilling site called "Buckskin" is presented as a stereographic projection, which shows the horizon as a circle. The MAHLI camera...

NASA's Curiosity Mars rover began close-up investigation of a target called "Marimba," on lower Mount Sharp, during the week preceding the fourth anniversary of the mission's Aug. 6, 2016, landing....

This illustration shows the locations and interactions of volatiles on Mars. Volatiles are molecules that readily evaporate, converting to their gaseous form, such as water and carbon dioxide.

A separate electronics box will allow the Mastcam to process images independently of the main rover computer system. Image credit: NASA/JPL-Caltech/MSSS

Standing atop a payload transporter, the Atlas V rocket payload fairing containing NASA's Mars Science Laboratory (MSL) spacecraft rolls out of the Payload Hazardous Servicing Facility at Kennedy S...
