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.
This image from NASA's Mars rover Curiosity provides a comparison for how big the moons of Mars appear to be, as seen from the surface of Mars, in relation to the size that Earth's moon appears to be when seen from the surface of Earth.
This view of the two moons of Mars comes from a set of images taken by NASA's Mars rover Curiosity as the larger moon, Phobos, passed in front of the smaller one, Deimos, from Curiosity's perspective, on Aug. 1, 2013.
This mosaic view from the Mast Camera (Mastcam) on NASA's Mars rover Curiosity shows textural characteristics and shapes of an outcrop called 'Point Lake.' The outcrop is about 20 inches (half a meter) high and pockmarked with holes.
