NASA's Mars rover Curiosity cut a wheel scuff mark into a wind-formed ripple at the "Rocknest" site to give researchers a better opportunity to examine the particle-size distribution of the materia...

Arm and Mast of NASA Mars Rover Curiosity

This view from NASA's Curiosity Mars rover shows an example of discoloration closely linked to fractures in the Stimson formation sandstone on lower Mount Sharp. The pattern is evident along two p...

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

Relive the nail-biting terror and joy as NASA's Curiosity rover successfully landed on Mars the evening of Aug. 5 PDT (morning of Aug. 6 EDT).

This stereo image from the Mast Camera (Mastcam) on NASA's Mars rover Curiosity shows a rock outcrop called "Hottah," cited as evidence for vigorous flow of water in a long-ago Martian stream. The ...

This graphic shows key features of the Tunable Laser Spectrometer (TLS), one of the instruments within the laboratory suite named Sample Analysis at Mars (SAM) aboard NASA's Curiosity Mars rover.

Curiosity's "eyes" (the Mastcam) are shrouded in a silvery material, awaiting their first look around the clean room at NASA’s Jet Propulsion Laboratory, where the rover is being built.

This series of images shows the Martian moon Deimos as it crossed in front of the Sun, as seen by NASA's Curiosity Mars rover on Sunday, March 17, 2019 (the 2,350th Martian day, or sol, of the miss...

This is an artist concept of the Atlas V541 launch vehicle that will carry NASA's Curiosity rover on its way to Mars.

This scene combines seven images from the telephoto-lens camera on the right side of the Mast Camera (Mastcam) instrument on NASA's Mars rover Curiosity.

Curiosity prepares for a second drilling and a tutorial on the complicated choreography to get the drill sample to her instruments.

This view from the wide-angle Hazard Avoidance Camera on the front of NASA's Curiosity Mars Rover shows the rover's drill in position for a mini-drill test to assess whether a rock target called "M...

Mars Science Laboratory mission scientists, flight controllers, managers and administrators raise their hands to a cheering crowd at a news conference following the successful landing of NASA’s Cur...

A blink pair of images taken before and after Curiosity performed a "mini drill" test on a Martian rock shows changes resulting from that activity.

Curiosity science team member William Dietrich explores the relationship between river fans found in California's Death Valley on Earth and similar fans in Gale Crater on Mars.

It takes a whole team to operate Curiosity's arm. Pictured here are just a few of the team members who put their "muscle" to work every day to help operate Curiosity's arm on Mars.

The foreground of this scene from the Mastcam on NASA's Curiosity Mars rover shows purple-hued rocks near the rover's late-2016 location. The middle distance includes future destinations for the ro...

This map shows the route driven by NASA's Curiosity Mars rover (blue line) and locations where the rover's ChemCam instrument detected the element boron (dots, colored by abundance of boron accordi...

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...

NASA’s Curiosity rover recently made its most challenging climb on Mars. Curiosity faced a steep, slippery slope on its journey up Mount Sharp, so rover drivers had to come up with a creative detou...

A "scarecrow" rover at NASA's JPL drives over a sensor while testing a new driving algorithm. Engineers created the algorithm to reduce wheel wear on the Mars Curiosity rover.

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 long journey to Mars through the harsh environment of space confronts the Curiosity navigation team with a long list of challenges to get the spacecraft safely to its destination.

NASA's Curiosity Mars rover has driven within robotic-arm's reach of the sandstone slab at the center of this April 23 view from the rover's Mast Camera.
