Mars drive

NASA shows the Mars rover Curiosity at a pit stop, a shallow depression called "Yellowknife Bay."  It took the image on the 125th Martian day, or sol, of the mission, Dec. 12, 2012, just after finishing that sol's drive. The Sol 125 drive entered Yellowknife Bay and covered about 86 feet. The descent into the basin crossed a step about 2 feet high, visible in the upper half of this image. Curiosity will now head for Mount Sharp in mid-February after it drills into its first rock.

Mountain views

A chapter of the layered geological history of Mars is laid bare in this color image from NASA's Curiosity rover showing the base of Mount Sharp, the rover's eventual science destination. The image is a portion of a larger image taken by Curiosity's 100-millimeter Mast Camera on Aug. 23, 2012. Scientists enhanced the color in one version to show the Martian scene under the lighting conditions we have on Earth, which helps in analyzing the terrain. The pointy mound in the center of the image, looming above the rover-sized rock, is about 1,000 feet across and 300 feet high.
