In this image, the scoop on NASA's Curiosity rover shows the larger soil particles that were too big to filter through a sample-processing sieve that is porous only to particles less than 0.006 inc...

NASA’s Curiosity left several sets of tracks where the rover experienced a fault, or unexpected stoppage mid-drive, while attempting the most difficult climb the mission has faced: a slope with a s...

This movie clip shows the larger of Mars' two moons, Phobos, passing in front of the smaller Martian moon, Deimos, as observed by NASA's Mars rover Curiosity.

The Mars Hand Lens Imager on NASA's Curiosity Mars rover provided this nighttime view of a hole produced by the rover's drill and, inside the hole, a line of scars produced by the rover's rock-zapp...

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 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.

This pair of images shows effects of one Martian day of wind blowing sand underneath NASA's Curiosity Mars rover on a non-driving day for the rover. Each image was taken just after sundown by the r...

This screen grab shows a sample - not actual data - of the kinds of Mars weather reports we will be getting from NASA's Curiosity rover

This "thumbnail" image illustrates the size of the first image expected from NASA's Curiosity rover. It was taken by a rover engineering model during a test session in the Mars Yard at NASA's Jet P...

Pictured here are a few of the women working on Mars with the Curiosity test rover model in the background. The image was taken in the "Mars Yard" where the ground test model of the Curiosity rover...

This self-portrait of NASA's Curiosity Mars rover shows the vehicle at the "Big Sky" site, where its drill collected the mission's fifth taste of Mount Sharp. It was taken on Oct. 6, 2015, PDT.

Testing of the robotic arm on NASA's Mars rover Curiosity on Sept. 3, 2010, included movements of the arm while the rover was on a table tilted to 20 degrees to simulate a sloped surface on Mars.

This artist concept features NASA's Mars Science Laboratory Curiosity rover, a mobile robot for investigating Mars' past or present ability to sustain microbial life.

This full-resolution self-portrait shows the deck of NASA's Curiosity rover from the rover's Navigation cameras.

NASA's Curiosity rover pinged the ground with neutrons for the first time, a process called active neutron sounding, on Aug. 17, 2012.

Technicians in the Payload Hazardous Servicing Facility at NASA's Kennedy Space Center in Florida put NASA's Mars Science Laboratory (MSL) rover, known as Curiosity, through a series of rotation te...

Testing of the cruise stage for NASA's Mars Science Laboratory in August 2010 included a session in a facility that simulates the environment found in interplanetary space.

With a unique view taken from inside Vertical Integration Facility (VIF) at Launch Complex 41 at Cape Canaveral Air Force Station in Florida, an overhead crane lifts the Centaur upper stage for the...

The sparks that appear on the baseball-sized rock result from the laser of the ChemCam instrument on NASA's Curiosity Mars rover hitting the rock. (No audio)

This image shows a close-up of track marks from the first test drive of NASA's Curiosity rover. The rover's arm is visible in the foreground.

This map shows the route driven by NASA's Curiosity Mars in its approach to and April 1, 2014, arrival at a waypoint called "the Kimberley," which rover team scientists chose in 2013 as the locatio...

This is an artist's concept of the Mars Science Laboratory Curiosity rover parachute system.

This animated blink comparison shows five versions of observations that NASA's Curiosity rover made about one hour apart while Mercury was passing in front of the sun on June 3, 2014. Two sunspots...
