This photo provided by NASA's Jet Propulsion Laboratory shows the gravel on the surface of Mars' Gale Crater where the Curiosity rover landed early Monday, Aug. 6, 2012, about 12:32 a.m. CDT. On the horizon is the rim of the crater. Part of the spring that released the lens' dust cover can be seen at the bottom right, near the rover's wheel. At top left is part of the rover's power supply. The lines across the top are an artifact from the sensor since the camera is looking into the sun. (NASA / JPL-Caltech, Associated Press)
