This is a reduced version of panorama from NASA's Mars rover Curiosity with 1.3 billion pixels in the full-resolution version. It shows Curiosity at the "Rocknest" site where the rover scooped up samples of windblown dust and sand. Curiosity used three cameras to take the component images on several different days between Oct. 5 and Nov. 16, 2012.
PASADENA, Calif. -- A billion-pixel view from the surface of Mars, from NASA's Mars rover Curiosity, offers armchair explorers a way to examine one part of the Red Planet in great detail.
The first NASA-produced view from the surface of Mars larger than one billion pixels stitches together nearly 900 exposures taken by cameras onboard Curiosity and shows details of the landscape along the rover's route.
The 1.3-billion-pixel image is available for perusal with pan and zoom tools at: http://mars.nasa.gov/bp1/ and a scaled down version (~159MB) is available for direct download here: http://www.jpl.nasa.gov/spaceimages/details.php?id=PIA16919.
