Replicating Martian Dunes

The Mars Hand Lens Imager (MAHLI) on the arm of NASA's Mars rover Curiosity was positioned about 4 inches (10 centimeters) from the surface of the "Point Lake" outcrop when it took this image of a ...

The ChemCam instrument for NASA's Mars Science Laboratory mission uses a pulsed laser beam to vaporize a pinhead-size target, producing a flash of light from the ionized material -- plasma -- that ...

This image comparison shows a view through a Hazard-Avoidance camera on NASA's Curiosity rover before and after the clear dust cover was removed.

This image, taken with the High Resolution Imaging Science Experiment (HiRISE) camera, shows a mesa within the "Murray Buttes" area on Mars showing a complex fracture pattern (black arrow) protrudi...

This image from the Mast Camera (Mastcam) on NASA's Curiosity Mars rover shows a portion of the pale rock outcrop that includes the "Bonanza King" target chosen for evaluation as the mission's four...

Radar Testing for Mars Science Labotatory

This mosaic view from the Mast Camera (Mastcam) on NASA's Mars rover Curiosity shows textural characteristics and shapes of an outcrop called "Point Lake."

At the bottom of this valley, called Gediz Vallis, is a mound of boulders and debris that are believed to have been swept there by wet landslides billions of years ago. The rover team hopes to get ...

Decades of work preparing a miniaturized laboratory for identifying minerals on Mars have also yielded spinoff versions with diverse applications on Earth and, possibly, the moon.

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.

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

A view from the "Kimberley" formation on Mars taken by NASA's Curiosity rover. The strata in the foreground dip towards the base of Mount Sharp, indicating the ancient depression that existed befor...

Create a video game that lets players explore the Red Planet with a helicopter like the one going to Mars with NASA's Perseverance rover!

NASA's Curiosity Mars rover examined both the "Greenhorn" and "Big Sky" targets with the rover's Alpha Particle X-ray Spectrometer (APXS) instrument. Greenhorn is located within an altered fracture...

At different locations on the surface of the same rock, scientists can use the Mast Camera (Mastcam) on NASA's Mars rover Curiosity to measure the amount of reflected light at a series of different...

NASA's Curiosity Mars rover used its black-and-white navigation cameras to capture panoramas of "Marker Band Valley" at two times of day on April 8. Color was added to a combination of both panoram...

This image maps the traverse of NASA's Mars rover Curiosity from "Bradbury Landing" to "Yellowknife Bay," with an inset documenting a change in the ground's thermal properties with arrival at a dif...

"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...

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...

The Sample Analysis at Mars (SAM) instrument for NASA's Mars Science Laboratory mission will study chemistry of rocks, soil and air as the mission's rover, Curiosity, investigates Gale Crater on Mars.

NASA’s Curiosity Mars rover captured this 360-degree panorama near a location nicknamed “Sierra Maigualida” on May 22, 2022, the 3,481st Martian day, or sol, of the mission. The panorama is made up...

The right Mast Camera (Mastcam) of NASA's Curiosity Mars rover provided this view of the lower stratigraphy at "Yellowknife Bay" inside Gale Crater on Mars.

For at least a couple of days, the science team of NASA's Mars rover Curiosity is focused on a full-bore science campaign at a tantalizing, rocky site informally called "Darwin."

With the wheels and suspension system already installed onto one side of NASA's Mars rover Curiosity the previous day, spacecraft engineers and technicians prepare the other side's mobility subsyst...

The "keys" to NASA's Mars rovers are in the capable hands of the official rover drivers. Learn how they operate the vehicles from millions of miles away in this 60-second video from NASA's Jet Prop...
