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.
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.
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.
Nodules of Cemented Sand Grains Within Martian Sandstone
This view from NASA's Curiosity shows nodules exposed in sandstone that is part of the Stimson geological unit on Mount Sharp, Mars. The nodules can be seen to consist of grains of sand cemented together.
The Mars Hand Lens Imager (MAHLI) camera on the robotic arm of NASA's Curiosity Mars rover used electric lights at night to illuminate this view of Martian sand grains dumped on the ground after sorting with a sieve.
This self-portrait of NASA's Curiosity Mars rover shows the vehicle at 'Namib Dune,' where the rover's activities included scuffing into the dune with a wheel and scooping samples of sand for laboratory analysis.
This view shows grains of sand where NASA's Curiosity Mars rover was driven into a shallow sand sheet near a large dune. The disturbance by the wheel exposed interior material of the sand body, including finer sand grains than on the undisturbed surface.
This view from the Mars Hand Lens Imager (MAHLI) on the arm of NASA's Curiosity Mars rover shows a combination of dark and light material within a mineral vein at a site called 'Garden City' on lower Mount Sharp.
Injection of Light Material into an Older Dark Vein
Light material emplaced within darker vein material is seen in this view of a mineral vein at the 'Garden City' site on lower Mount Sharp, Mars. The Mars Hand Lens Imager (MAHLI) on the arm of NASA's Curiosity Mars Rover took the image on April 4, 2015.
Test Rover at JPL During Preparation for Mars Rover's Low-Angle Selfie
This view of a test rover at NASA's Jet Propulsion Laboratory, Pasadena, California, results from advance testing of arm positions and camera pointings for taking a low-angle self-portrait of NASA's Curiosity Mars rover.
Curiosity Low-Angle Self-Portrait at 'Buckskin' Drilling Site on Mount Sharp
This low-angle self-portrait of NASA's Curiosity Mars rover shows the vehicle above the 'Buckskin' rock target, where the mission collected its seventh drilled sample. The site is in the 'Marias Pass' area of lower Mount Sharp.
Round-Horizon Version of Curiosity's Low-Angle Selfie at 'Buckskin'
This version of a self-portrait of NASA's Curiosity Mars rover at a drilling site called 'Buckskin' on lower Mount Sharp is presented as a stereographic projection, which shows the horizon as a circle.
