This color thumbnail image was obtained by NASA's Curiosity rover during its descent to the surface of Mars on Aug. 5, 2012, and transmitted to Spaceflight Operations Facility for NASA's Mars Science Laboratory Curiosity rover at Jet Propulsion Laboratory (JPL) in Pasadena, California. This image from Curiosity's Mars Descent Imager reveals surface features including relatively dark dunes, degraded impact craters and other geologic features. The image was obtained one minute 16 seconds before touchdown. This is but one of hundreds of frames that were acquired during the descent to the surface.
