'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.
Curiosity's First Scoop of Mars, in Vibration Movie
This image from a video shows the first Martian material collected by the scoop on the robotic arm of NASA's Mars rover Curiosity. The material vibrated inside the scoop after it was lifted from the ground.
The color cameras on NASA's Mars rover Curiosity, including the pair that make up the rover's Mastcam instrument, use the same type of Bayer pattern RGB filter as found in typical commercial color cameras.
Panoramic View From 'Rocknest' Position of Curiosity Mars Rover
The image, which has been white-balanced to show what the rocks and soils in it would look like if they were on Earth, is a mosaic of images taken at a site called 'Rocknest' while NASA's Mars rover Curiosity was working.
This pair of images from the Mast Camera on NASA's Curiosity rover shows the upper portion of a wind-blown deposit dubbed 'Rocknest.' At left, colors are unmodified, showing the scene as it would appear on Mars, which has a dusty red-colored atmosphere.
This set of images compares the 'Link' outcrop of rocks on Mars (left) with similar rocks seen on Earth (right). The 'Link' outcrop shows rounded gravel fragments, or clasts, up to a couple inches (few centimeters), within the rock outcrop.
This mosaic of images from the Mast Camera (Mastcam) on NASA's Mars rover Curiosity shows Mount Sharp in a white-balanced color adjustment that makes the sky look overly blue but shows the terrain as if under Earth-like lighting.
Mast Camera and Its Calibration Target on Curiosity Rover
This set of images illustrates the twin cameras of the Mastcam instrument on NASA's Curiosity Mars rover (upper left), the Mastcam calibration target (lower center), and the locations of the cameras and target on the rover.
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 Mastcam on NASA's Mars rover Curiosity.
NASA's Curiosity rover found evidence for an ancient, flowing stream on Mars at a few sites, including the rock outcrop pictured here, which the science team has named 'Hottah' after Hottah Lake in Canada's Northwest Territories.
This pairing illustrates the first time that NASA's Mars rover Curiosity collected a scoop of soil on Mars. At right, the ground location 'Rocknest,' at left, after the scoop of sand and dust had been removed.
This close-up image shows the first target NASA's Curiosity rover aims to zap with its Chemistry and Camera (ChemCam) instrument. The instrument will analyze that spark with a telescope and identify the chemical elements in the target.
