This image from the Mars Hand Lens Imager (MAHLI) on NASA's Mars rover Curiosity shows a patch of rock cleaned by the first use of the rover's Dust Removal Tool (DRT). The tool is a motorized, wire-bristle brush on the turret at the end of the rover's arm. It was first used on Jan. 6, 2013 – the 150th Martian day, or sol, of the mission.

The sinuous rock feature in the lower center of this mosaic of images recorded by Curiosity is called "Snake River." The images in the mosaic were taken by Curiosity's Navigation Camera during the 133rd sol of the rover's mission on Mars (Dec. 20, 2012).

Curiosity used its left Navigation Camera to record this view of the step down into a shallow depression called "Yellowknife Bay." It took the image on the 125th sol of the mission (Dec. 12, 2012), just after finishing that sol's drive.

This panorama is a mosaic of images taken by the Mast Camera (Mastcam) on Curiosity during the 106th sol of the mission (Nov. 22, 2012). The rover was near a location called "Point Lake" for an overlook of "Yellowknife Bay," which is in the left third of this scene, in the middle distance.
