This image is from a series of test images to calibrate the 34-millimeter Mast Camera on NASA's Curiosity rover. It was taken on Aug. 23, 2012 and looks south-southwest from the rover's landing site.

Side-by-side images depict NASA's Curiosity rover (left) and a moon buggy driven during the Apollo 16 mission.

This artist's concept shows how the cruise stage de-spins outside the martian atmosphere, turns to entry position, suffers peak heating just after entry, then peak deceleration, before deploying a ...

John Grotzinger, Curiosity's principal investigator, narrates an aerial tour of the rover's past, present and future traverses on the Red Planet.

Curiosity's DAN instrument for checking hydration levels in the ground beneath the rover detected an unusually high amount at a site near "Marias Pass," prompting repeated passes over the area to m...

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 ...

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.

This artist's concept depicts the interaction of NASA's Mars Science Laboratory spacecraft with the upper atmosphere of Mars during the entry, descent and landing of the Curiosity rover onto the Ma...

This diagram depicts rivers entering a lake. Where the water's flow decelerates, sediments drop out, and a delta forms, depositing a prism of sediment that tapers out toward the lake's interior. Pr...

Two images of the night sky were combined to show Earth and Venus as seen by the Mast Camera aboard NASA's Curiosity Mars rover on June 5, 2020, the 2,784th Martian day, or sol, of the mission. Bot...

This view from the Mast Camera (Mastcam) on NASA's Curiosity Mars rover shows a site with a network of prominent mineral veins below a cap rock ridge on lower Mount Sharp.

This patch of Martian bedrock, about 2 feet (70 centimeters) across, is finely layered rock with some pea-size inclusions. It lies near the lowest point of the "Pahrump Hills" outcrop, which forms ...

The first three elements for NASA's Mars Science Laboratory (MSL) arrive at NASA Kennedy Space Center's Shuttle Landing Facility aboard an Air Force C-17 cargo plane.

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 image of terrain inside Mars' Gale Crater and the inset of the calibration target for the Mast Camera (Mastcam) on NASA's Mars rover Curiosity illustrate how the calibration target aids resear...

This artist's scoreboard displays a fictional game between Mars and Earth, with Mars in the lead. It refers to the success rate of sending missions to Mars, both as orbiters and landers.

This is an artist's concept of NASA's Mars Science Laboratory spacecraft during its cruise phase between launch and final approach to Mars.

This full-resolution image shows part of the deck of NASA's Curiosity rover taken from one of the rover's Navigation cameras looking toward the back left of the rover.

This diagram illustrates how Mount Sharp in Gale Crater, Mars, where NASA's Curiosity rover is now driving, might have formed billions of years ago.

This stereo view from NASA's Curiosity Mars Rover shows the downwind side of a dune about 13 feet high within the Bagnold Dunes on Mars. The image appears three-dimensional when viewed through red-...

The Entry, Descent and Landing team celebrate after the successful landing of the Curiosity rover on Mars.

These 26 holes represent each of the rock samples NASA's Curiosity Mars rover has collected as of early July 2020. A map in the upper left shows where the holes were drilled along the rover's route...

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."

Prominent mineral veins at the "Garden City" site examined by NASA's Curiosity Mars rover vary in thickness and brightness, as seen in this image from Curiosity's Mast Camera (Mastcam). The image c...

This scene shows NASA's Curiosity Mars rover at a location called "Windjana," where the rover found rocks containing manganese-oxide minerals, which require abundant water and strongly oxidizing co...
