A grid of small polygons on the Martian rock surface near the right edge of this view may have originated as cracks in drying mud more than 3 billion years ago. Multiple images of this view were combined for this view from NASA's Curiosity Mars rover.
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 combines three images taken by NASA's Curiosity Mars rover on Dec. 31, 2016.
Color Variations on Mount Sharp, Mars (White Balanced)
The foreground of this scene from NASA's Curiosity Mars rover shows purple-hued rocks near the rover's late-2016 location on lower Mount Sharp. Variations in color of the rocks hint at the diversity of their composition.
Curiosity's Rock or Soil Sampling Sites on Mars, Through November 2016
This graphic maps locations of the sites where NASA's Curiosity collected its first 19 rock or soil samples for analysis by laboratory instruments inside the vehicle. It also presents images of the drilled holes where 15 rock-powder samples were acquired.
Martian Terrain Near Curiosity's 'Precipice' Target
This Dec. 2, 2016, view from the Navcam on the mast of NASA's Curiosity Mars Rover shows rocky ground within view while the rover was working at an intended drilling site called 'Precipice' on lower Mount Sharp.
Curiosity Rover Finds and Examines a Meteorite on Mars
The dark, smooth-surfaced object at the center of this Oct. 30, 2016, image from the Mast Camera (Mastcam) on NASA's Curiosity Mars rover was examined with laser pulses and confirmed to be an iron-nickel meteorite.
Iron-Nickel Meteorite Zapped by Mars Rover's Laser
The dark, golf-ball-size object in this composite, colorized view from NASA's Curiosity Mars rover shows a grid of shiny dots where ChemCam had fired laser pulses used for determining the chemical elements in the target's composition.
Curiosity Destinations for Second Extended Mission
This map shows the route driven by NASA's Curiosity Mars rover from the location where it landed in August 2012 to its location in September 2016 at 'Murray Buttes', and the path planned for reaching destination at lower Mount Sharp.
Curiosity's First 16 Rock or Soil Sampling Sites on Mars
This graphic maps the first 16 sites where NASA's Curiosity Mars rover collected rock or soil samples for analysis by laboratory instruments inside the vehicle. It also presents images of the drilled holes where 14 rock-powder samples were acquired.
The two prominent mesas in this view of Mars' 'Murray Buttes' region from NASA's Curiosity Mars rover are about 260 feet (about 80 meters) apart. Upper Mount Sharp is the salmon-hued mound dominating the horizon between the scene's two prominent mesas.
Rover's Panorama Taken Amid 'Murray Buttes' on Mars
This 360-degree panorama was acquired NASA's Curiosity Mars rover while the rover was in an area called 'Murray Buttes' on lower Mount Sharp, one of the most scenic landscapes yet visited by any Mars rover.
Isotopic Clues to Mars' Crust-Atmosphere Interactions
NASA's Sample Analysis at Mars (SAM) laboratory suite inside NASA's Curiosity Mars rover has measured the isotope ratios of xenon and krypton in Mars' atmosphere and can explain why they are more abundant in the Martian atmosphere than expected.
Breccia-Conglomerate Rocks on Lower Mount Sharp, Mars (Stereo)
The rock in the foreground at right in this 3D scene is informally named 'Balombo.' The group of boulders is at a site called 'Bimbe.' NASA's Curiosity Mars Rover shows boulders composed of pebble-size and larger rock fragments.
Curiosity's Arm Over 'Marimba' Target on Mount Sharp
NASA's Curiosity Mars rover began close-up investigation of a target called 'Marimba,' on lower Mount Sharp, during the week preceding the fourth anniversary of the mission's dramatic sky-crane landing.
