Camera on Curiosity's Arm as Seen by Camera on Mast Space Wallpaper
About this Image
The left eye of the Mast Camera (Mastcam) on NASA's Mars rover Curiosity took this image of the camera on the rover's arm, the Mars Hand Lens Imager (MAHLI) in this space wallpaper during the 30th Martian day, or sol, of the rover's mission on Mars taken Sept.5, 2012.
The image shows that MAHLI has a thin film or coating of Martian dust on it. This dust accumulated during Curiosity's final descent to the Martian surface, as the Mars Science Laboratory spacecraft's descent stage (or sky crane) engines were disrupting the surface nearby.
