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...

NASA's Mars rovers keep getting bigger. This photo provides a comparison of the wheel sizes for three generations of them.

This view from the Mastcam on NASA's Curiosity Mars rover shows dramatic buttes and layers on the lower flank of Mount Sharp. It was taken on Sept. 7, 2013, from near the waypoint called "Darwin" o...

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.

A view from NASA's Mars Reconnaissance Orbiter on April 8, 2015, catches sight of NASA's Curiosity Mars rover passing through a valley called "Artist's Drive" on the lower slope of Mount Sharp.

NASA’s Curiosity used its Mastcam to capture this impact crater in a location nicknamed “Jau” on July 25, the 3,899th Martian day, or sol, of the mission. This was one of dozens of impact craters C...

This view of a Martian rock target called "Harrison" merges images from two cameras on NASA's Curiosity Mars rover to provide both color and microscopic detail.

This image graphs four gases released ("evolved") when powdered rock from the target rock "Cumberland" was heated inside the Sample Analysis at Mars (SAM) instrument suite on NASA's Curiosity Mars ...

Testing of the robotic arm on NASA's Mars rover Curiosity on Sept. 3, 2010, included movements of the arm while the rover was on a table tilted to 20 degrees to simulate a sloped surface on Mars.

Color coding in this image of Gale Crater on Mars represents differences in elevation, with blue relatively low and tan relatively high.
