NASA’s Curiosity Mars rover used its Mast Camera, or Mastcam, to capture this panorama of a hill nicknamed "Bolivar" and adjacent sand ridges on Aug. 23, the 3,572nd Martian day, or sol, of the mis...

The network of cracks in this Martian rock slab called "Old Soaker" may have formed from the drying of a mud layer more than 3 billion years ago.

This artists concept of MSL is a still from the MSL Mission Overview video. It shows MSL on the surface of Mars.

This image from the Mast Camera (Mastcam) on NASA's Mars rover Curiosity shows inclined layering known as cross-bedding in an outcrop called "Shaler" on a scale of a few tenths of meters, or decime...

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 529...

A New Perspective on Murray Ridge

Two 2001 images from NASA's Mars Global Surveyor orbiter show a dramatic change in the planet's appearance during a dust storm.

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 selecte...

The location of a rock target called "Knorr" is indicated on this self-portrait of the Curiosity rover in the "Yellowknife Bay" area.

NASA's Curiosity Mars rover recorded this stereo view of various rock types at waypoint called "the Kimberley" shortly after arriving at the location on April 2, 2014. The scene appears three dimen...
