This self-portrait of NASA's Curiosity Mars rover shows the vehicle on Vera Rubin Ridge, which it's been investigating for the past several months.

NASA's Mars rover Curiosity heads on the long journey to the mission's main destination, Mount Sharp.

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.

The two bodies in this portion of an evening-sky view by NASA's Mars rover Curiosity are Earth and Earth's moon. The rover's Mast Camera (Mastcam) imaged them in the twilight sky of Curiosity's 529...

“Selfie” of the Curiosity rover with inset showing the SAM instrument prior to installation on the rover. 

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.

This is how AEGIS sees the Martian surface. All targets found by the A.I. program are outlined: blue targets are rejected, while red are retained. The top-ranked target is shaded green; if there's ...

In this photo, two engineers from NASA Jet Propulsion Laboratory and Alliance Spacesystems are standing in a white room on either side of the Mars Science Laboratory rover's robotic arm. They are d...

This map shows the location of "Cumberland," the second rock-drilling target for NASA's Mars rover Curiosity, in relation to the rover's first drilling target, "John Klein," within the southwestern...

The Chemistry and Camera (ChemCam) instrument on NASA's Curiosity Mars rover fired its laser 50 times at its onboard graphite target during the 27th Martian day, or sol, of the rover's work on Mars...

In a shallow depression called "Yellowknife Bay," the NASA Mars rover Curiosity drove to an edge of the feature during the 130th Martian day, or sol, of the mission (Dec. 17, 2012) and used its Nav...

Five years of Martian discoveries after seven minutes of terror.

"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...

The sand dunes on Earth sometimes resemble those on Mars. However, Martian dunes are many times larger than those we see on Earth. This image shows engineers seeking out the best place to test dr...

This May 12, 2014, view from the Mars Hand Lens Imager (MAHLI) in NASA's Curiosity Mars Rover shows the rock target "Windjana" and its immediate surroundings after inspection of the site by the rov...

This is the left-eye member of a stereo pair of images of the Mars Science Laboratory mission's rover, Curiosity.

This image from the front Hazcam on NASA's Curiosity Mars rover shows the rover's drill in place during a test of whether the rock beneath it, "Bonanza King," would be an acceptable target for dril...

NASA’s Curiosity Mars rover captured these "sun rays" shining through clouds at sunset on Feb. 2, 2023, the 3,730th Martian day, or sol, of the mission. It was the first time that sun rays, also kn...

Over the years, NASA has sent five robotic vehicles, called rovers, to Mars. The names of the five rovers are: Sojourner, Spirit and Opportunity, Curiosity, and Perseverance.

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...
