Sandy Dunes

NASA's Curiosity Mars rover used its Dust Removal Tool to brush aside reddish dust, revealing gray, less-oxidized rock material at a target called "Bonanza King," visible in this Aug. 17, 2014, ima...

This view of channels on Mars came from NASA's Mariner 9 orbiter. In 1971, Mariner 9 became the first spacecraft to enter orbit around Mars.

This grid shows all 36 holes drilled by NASA’s Curiosity Mars rover using the drill on the end of its robotic arm. The rover analyzes powderized rock from the drilling activities. The images in the...

This 360-degree vista was acquired on Aug. 5, 2016, by the Mastcam on NASA's Curiosity Mars rover as the rover neared features called "Murray Buttes" on lower Mount Sharp. The dark, flat-topped mes...

The Mars Hand Lens Imager (MAHLI) camera will fly on NASA's Mars Science Laboratory mission, launching in late 2011.

Curiosity viewed sloping buttes and layered outcrops as it exited the "Murray Buttes" region on lower Mount Sharp, Sept. 9, 2016.

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.

This two-step animation shows before and after views of a patch of sandstone scrubbed with the Dust Removal Tool, a wire-bristle brush, on NASA's Curiosity Mars rover. Both images were taken April ...

Using the elements of art — shape, line, color, texture, value — learners of all ages create a beautiful piece of art while learning to recognize geologic and atmospheric features of solar system o...

This Picasso-like self portrait of NASA's Curiosity rover was taken by its Navigation cameras, located on the now-upright mast.

This portion of an image from the High Resolution Imaging Science Experiment (HiRISE) on NASA's Mars Reconnaissance Orbiter has been annotated to show the relative positions between NASA's Curiosit...

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.

NASA's Curiosity rover took this selfie on Oct. 11, 2019, the 2,553rd Martian day, or sol, of its mission. The rover drilled twice in this location, which is nicknamed "Glen Etive."

Engineers test the Scarecrow rover on a dunes obstacle course. This test was done in the Dumont Dunes in California's Mojave Desert, near Death Valley.

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

This image shows the quadrangle where NASA's Curiosity rover landed, now called Yellowknife.

In this project, you'll do an experiment to explore the science behind a mystery that puzzled scientists for years. Read on to play the part of a NASA scientist and learn about what's creating brig...

Sensors on two finger-like mini-booms extending horizontally from the mast of NASA's Mars rover Curiosity will monitor wind speed, wind direction and air temperature.

Scarecrow, a mobility-testing model for NASA's Mars Science Laboratory, easily traverses large rocks in the Mars Yard testing area at NASA's Jet Propulsion Laboratory.

Sandstone layers with varying resistance to erosion are evident in this Martian scene recorded by the Mast Camera on NASA's Curiosity Mars rover on Feb. 25, 2014, about one-quarter mile (about 400 ...

This image illustrates the principals of a technique called "laser-induced breakdown spectroscopy," which the Chemistry and Camera (ChemCam) instrument will use on Mars.

The NASA and Mars Science Laboratory (MSL) logos appear above the American flag and Atlas logo on the payload fairing atop the 197-foot-tall United Launch Alliance Atlas V rocket.

NASA's Curiosity Mars rover took this selfie at a location nicknamed "Mary Anning" after a 19th century English paleontologist. Curiosity snagged three samples of drilled rock at this site on its w...

Students decide what they want to learn from a robotic mission to Mars.

This video clip shows the larger of the two moons of Mars, Phobos, passing directly in front of the sun, in an eclipse photographed by NASA's Mars rover Curiosity. (No audio)
