The left eye of the Mast Camera (Mastcam) on NASA's Mars rover Curiosity took this image of the camera on the rover's arm, the Mars Hand Lens Imager (MAHLI), during the 30th Martian day, or sol, of...

NASA's Curiosity Mars rover recorded this view of various rock types at waypoint called "the Kimberley" shortly after arriving at the location on April 2, 2014. The site offers a diversity of rock ...

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."

This grouping of two test rovers and a flight spare provides a graphic comparison of three generations of Mars rovers developed at NASA's Jet Propulsion Laboratory, Pasadena, Calif. The setting is ...

This full-resolution image from NASA's Curiosity shows the elbow joint of the rover's extended robotic arm on Aug. 20, 2012. The Navigation Camera captured this view.

In this Mars Reconnaissance Orbiter view of the Curiosity rover mission's waypoint called "the Kimberley," the red dot indicates the location of a sandstone target, "Windjana," selected for close-u...

The cruise stage of NASA's Mars Science Laboratory spacecraft is being prepared for final stacking of the spacecraft in this photograph from inside the Payload Hazardous Servicing Facility at NASA ...

Access Mars lets users visit several sites from the past five years of discoveries made by NASA's Curiosity rover.

In the middle of this image, three wheels are shown raised by a lift, with engineers on both sides of the wheels in the cleanroom, where the Curiosity rover is being assembled. The wheels are made ...

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. The view spans about 3 feet (90 centimeters) left-t...

This stereo view from the Navigation Camera (Navcam) on NASA's Curiosity Mars rover shows a 360-degree panorama around the location where the rover spent its 1,000th Martian day, or sol, on Mars. T...

The surface of the Martian rock target in this stereo, close-up image from the Curiosity rover's MAHLI camera includes small hollows with a "swallowtail" shape characteristic of gypsum crystals. Th...

If the atmosphere of Mars contains methane, various possibilities have been proposed for where the methane could come from and how it could disappear.

NASA's Curiosity Mars rover has driven within robotic-arm's reach of the sandstone slab at the center of this April 23 view from the rover's Mast Camera.

This graphic depicts paths by which carbon has been exchanged among Martian interior, surface rocks, polar caps, waters and atmosphere, and also depicts a mechanism by which it is lost from the atm...

This April 10, 2015, view from the Navigation Camera on NASA's Curiosity Mars rover shows the terrain ahead of the rover as it makes its way westward through a valley called "Artist's Drive."
