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.
This mosaic of images from the Mast Camera onboard NASA's Curiosity Mars rover shows a series of sedimentary deposits in the Glenelg area of Gale Crater, from a perspective in Yellowknife Bay looking toward west-northwest.
View of Yellowknife Bay Formation, with Drilling Sites
This mosaic of images from NASA's Curiosity shows geological members of the Yellowknife Bay formation, and the sites where Curiosity drilled into the lowest-lying member, called Sheepbed, at targets 'John Klein' and 'Cumberland'.
The rock 'Ithaca' is shown here with a rougher lower texture and smoother texture on top, and appears to be a piece of the local sedimentary bedrock protruding from the surrounding soil in Gale Crater as seen by NASA's Curiosity Mars rover.
