Within Rover's Reach at Mars Target Area 'Alexander Hills'
This view from ASA's Curiosity Mars rover shows a swath of bedrock called 'Alexander Hills,' which the rover approached for close-up inspection of selected targets. It is a mosaic of six frames taken on Nov. 23, 2014.
Fine-Grained, Finely Layered Rock at Base of Martian 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 part of the basal layer of Mount Sharp.
Erosion Resistance at 'Pink Cliffs' at Base of Martian Mount Sharp
This small ridge, about 3 feet long, appears to resist wind erosion more than the flatter plates around it. Such differences are among the traits NASA's Curiosity Mars rover is examining at selected rock targets at the base of Mount Sharp.
This image from NASA's Curiosity rover shows a sample of powdered rock extracted by the rover's drill from the 'Confidence Hills' target -- the first rock drilled after Curiosity reached the base of Mount Sharp in September 2014.
'Confidence Hills' -- The First Mount Sharp Drilling Site
This image shows the first holes drilled by NASA's Mars rover Curiosity at Mount Sharp. The loose material near the drill holes is drill tailings and an accumulation of dust that slid down the rock during drilling.
Curiosity Mars Rover's Approach to 'Pahrump Hills'
This southeastward-looking vista from the Mast Camera (Mastcam) on NASA's Curiosity Mars rover shows the 'Pahrump Hills' outcrop and surrounding terrain seen from a position about 70 feet (20 meters) northwest of the outcrop.
The 'Bonanza King' rock on Mars, pictured here, was tapped by the drill belonging to NASA's Mars rover Curiosity. The tapping resulted in sand piling up on the rock after drilling, showing the rock was not firmly in place.
Curiosity's Brushwork on Martian 'Bonanza King' Target
NASA's Curiosity Mars rover used the Dust Removal Tool on its robotic arm to brush aside reddish, more-oxidized dust, revealing a gray patch of less-oxidized rock material at a target called 'Bonanza King,' visible from the rover's Mastcam.
This Aug. 12, 2012, image from the Mastcam on NASA's Curiosity Mars rover shows an outcrop that includes the 'Bonanza King' rock under consideration as a drilling target. Raised ridges on the flat rocks are visible at right.
This rock encountered by NASA's Curiosity Mars rover is an iron meteorite called 'Lebanon,' similar in shape and luster to iron meteorites found on Mars by the previous generation of rovers, Spirit and Opportunity.
This frame from an animation shows five versions of observations that NASA's Curiosity made about one hour apart while Mercury was passing in front of the sun on June 3, 2014. Two sunspots, each about the diameter of Earth, also appear.
Differential Erosion at Work on Martian Sandstones
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 meters) from a planned waypoint called "the Kimberley."
This view of the twilight sky and Martian horizon taken by NASA's Curiosity Mars rover includes Earth as the brightest point of light in the night sky. Earth is a little left of center in the image, and our moon is just below Earth.
Curiosity Mars Rover's First Image of Earth and Earth's Moon
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 529th Martian day, or sol (Jan. 31, 2014).
Martian Rock 'Harrison' in Color, Showing Crystals
This view of a Martian rock target called /Harrison' merges images from two cameras onboard NASA's Curiosity Mars rover to provide both color and microscopic detail. The elongated crystals are likely feldspars, and the matrix is pyroxene-dominated.
