"Curiosity Rover's Stunning Martian Postcards"

NASA's Curiosity Mars rover captured a "postcard" of Marker Band Valley, an area in the "sulfate-bearing region" of Gale Crater, using its navigation cameras. The postcard is an artistic interpretation of the landscape, with color added over two black-and-white panoramas captured at different times of day. The resulting image shows the foothills of Mount Sharp, two hills, and the rover's three antennas and nuclear power source. The Radiation Assessment Detector instrument, which appears as a white circle in the lower right of the image, has been helping scientists learn how to protect the first astronauts sent to Mars from radiation on the planet's surface.
