A rock outcrop dubbed 'Missoula,' near Marias Pass on Mars, is seen in this image mosaic taken by NASA's Curiosity rover. Pale mudstone (bottom of outcrop) meets coarser sandstone (top) in this geological contact zone.
A rock fragment dubbed 'Lamoose' is shown in this picture taken by NASA's Curiosity rover. Like other nearby rocks in a portion of the 'Marias Pass' area of Mt. Sharp, Mars, it has unusually high concentrations of silica.
Night Close-up of Mineral Veins at 'Garden City,' Mars
This view from the Mars Hand Lens Imager on the arm of NASA's Curiosity Mars rover is a close-up of a two-tone mineral vein at a site called 'Garden City' on lower Mount Sharp. It was taken during night, illuminated by LEDs, on March 25, 2015.
Hole at 'Telegraph Peak' Drilled by Mars Rover Curiosity
This hole, with a diameter slightly smaller than a U.S. dime, was drilled by NASA's Curiosity Mars rover into a rock target called 'Telegraph Peak.' The rock is located within the basal layer of Mount Sharp. The hole was drilled on Feb. 24, 2015.
Lozenge-shaped crystals are evident in this magnified view of a Martian rock target called 'Mojave,' taken on Nov. 15, 2014, by NASA's Curiosity Mars rover. These features record concentration of dissolved salts, possibly in a drying lake.
This image from the Mars Hand Lens Imager (MAHLI) camera on NASA's Curiosity Mars rover shows an example of a type of geometrically distinctive feature that researchers are using Curiosity to examine at a mudstone outcrop at the base of Mount Sharp.
This image from the Mars Hand Lens Imager (MAHLI) camera on NASA's Curiosity Mars rover shows the first sample-collection hole drilled in Mount Sharp, the layered mountain that is the science destination of the rover's extended mission.
NASA's Curiosity Mars rover used the Mars Hand Lens Imager (MAHLI) camera on its arm to catch the first images of sparks produced by the rover's laser being shot at a rock on Mars. The left image is from before the laser zapped this rock, called 'Nova'.
Curiosity's ChemCam Examines Mars Rock Target 'Nova'
A Martian target rock called 'Nova,' shown here, displayed an increasing concentration of aluminum as a series of laser shots from NASA's Curiosity Mars rover penetrated through dust on the rock's surface.
Curiosity Self-Portrait at 'Windjana' Drilling Site
NASA's Curiosity Mars rover used the MAHLI camera at the end of its arm in April and May 2014 to take dozens of component images combined into this self-portrait where the rover drilled into a sandstone target called 'Windjana.'
Preparatory Drilling Test on Martian Target 'Windjana'
NASA's Curiosity Mars rover completed a shallow 'mini drill' test April 29, 2014, in preparation for full-depth drilling at a rock target called 'Windjana.' The hole results from the test is 0.63 inch across and about 0.8 inch deep.
Martian Sandstone Target 'Windjana' Before and After Brushing
This image from an animation shows a patch of sandstone scrubbed with the Dust Removal Tool, a wire-bristle brush, on NASA's Curiosity Mars rover. This rock target is called 'Windjana,' after a gorge in Western Australia.
Mars Hand Lens Imager Sends Ultra High-Res Photo from Mars
This image of a U.S. penny on a calibration target was taken by the Mars Hand Lens Imager (MAHLI) aboard NASA's Curiosity rover in Gale Crater on Mars. At 14 micrometers per pixel, this is the highest-resolution image that MAHLI can acquire.
Pebbly Sandstone Conglomerate Rock at Curiosity's 'Waypoint 1'
This mosaic of nine images taken at a location called 'Darwin,' inside Gale Crater, were taken by NASA's Mars rover Curiosity and shows detailed texture in a conglomerate rock bearing small pebbles and sand-size particles.
View From Curiosity's Arm-Mounted Camera After a Long Drive
The MAHLI camera on NASA's Curiosity rover is carried at an angle when the rover's arm is stowed for driving. Still, the camera is able to record views of the terrain Curiosity is crossing in Gale Crater.
