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.
This two-part illustration shows the context of the erosion-resistant, raised vein, called 'Catabola,' in an image from NASA's Curiosity's Mast Camera. The highest concentration of boron measured on Mars.
This map shows the route driven by NASA's Curiosity Mars rover (blue line) and locations where the rover's ChemCam instrument detected the element boron (dots, colored by abundance of boron according to the key at right).
Mineral Content Comparison at Two Gale Crater Sites
This graphic shows proportions of minerals identified in mudstone exposures at the 'Yellowknife Bay' location where NASA's Curiosity Mars rover first analyzed bedrock, in 2013, and at the 'Murray Buttes' area investigated in 2016.
Clay Mineral Crystal Structure Tied to Composition
This diagram illustrates how the dimensions of clay minerals' crystal structure are affected by which ions are present in the composition of the mineral. Different clay minerals were identified this way at two sites, 'Yellowknife Bay' and 'Murray Buttes'
Detecting a Difference in Clay Minerals at Two Gale Crater Sites
Data graphed here from the CheMin instrument on NASA's Mars Curiosity rover show a difference between clay minerals in powder drilled from mudstone outcrops at two locations, 'Yellowknife Bay' and 'Murray Buttes' in Mars' Gale Crater.
Mudstone Mineralogy from Curiosity's CheMin, 2013 to 2016
This series of pie charts shows similarities and differences in the mineral compositions of mudstones at 10 sites where NASA's Curiosity Mars rover collected rock-powder samples and analyzed them with the rover's Chemistry and Mineralogy instrument.
Late 2016 Map of NASA's Curiosity Mars Rover 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 December 2016, which is in the upper half of a geological unit called the Murray formation, on lower Mount Sharp.
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.
