Rock 'Tintina' Exposes 'Yellowknife Bay' Vein Material
This raw image of "Tintina," a broken rock fragment in a rover wheel track, was taken by Curiosity's Mast Camera (Mastcam). Image released March 18, 2013.
Hydration Map, Based on Mastcam Spectra, for broken rock 'Tintina'
On this image of the broken rock called "Tintina," color coding maps the amount of mineral hydration indicated by a ratio of near-infrared reflectance intensities measured by the Mast Camera (Mastcam) on NASA's Mars rover Curiosity. Image released March 18, 2013.
Filters for Color Imaging and for Science
The color cameras on NASA's Mars rover Curiosity, including the pair that make up the rover's Mast Camera (Mastcam) instrument, use the same type of Bayer pattern RGB filter as found in typical commercial color cameras. Image released March 18, 2013.
Using Curiosity's Mast Camera to View Scene in 'Natural' Color
This image of terrain inside Mars' Gale Crater and the inset of the calibration target for the Mast Camera (Mastcam) on NASA's Mars rover Curiosity illustrate how the calibration target aids researchers in adjusting images to estimate "natural" color, or approximately what the colors would look like if we were to view the scene ourselves on Mars, using the known colors of materials on the target. Image released March 18, 2013.
Using False Color from Curiosity's Mast Camera
This image of terrain inside Mars' Gale Crater and the inset of the calibration target for the Mast Camera (Mastcam) on NASA's Mars rover Curiosity illustrate how false color can be used to make differences more evident in the materials in the scene. Image released March 18, 2013.
Veins and Nodules at 'Knorr' Target in 'Yellowknife Bay' of Gale Crater
Light-toned nodules and veins are visible in this image from NASA's Mars rover Curiosity of a patch of sedimentary rock called "Knorr." Image released March 18, 2013.
'Raw,' 'Natural' and 'White-Balanced' Views of Martian Terrain
These three versions of the same image taken by the Mast Camera (Mastcam) on NASA's Mars rover Curiosity illustrate different choices that scientists can make in presenting the colors recorded by the camera. Image released March 18, 2013.
Bluish-Black Rock with White 'Crystals' on Mars
The Mast Camera (Mastcam) on NASA's Mars rover Curiosity showed researchers interesting color and patterns in this unnamed rock imaged during the 27th Martian day, or sol, of the rover's work on Mars (Sept. 2, 2012).
Two Different Aqueous Environments
This set of images compares rocks seen by NASA's Opportunity rover and Curiosity rover at two different parts of Mars. On the left is " Wopmay" rock, in Endurance Crater, Meridiani Planum, as studied by the Opportunity rover. On the right are the rocks of the "Sheepbed" unit in Yellowknife Bay, in Gale Crater, as seen by Curiosity. Image released March 12, 2013.
Minerals at 'Rocknest' and 'John Klein'
This side-by-side comparison shows the X-ray diffraction patterns of two different samples collected from the Martian surface by NASA's Curiosity rover. Image released March 12, 2013.
