NASA's Mars rover Curiosity used its Mast Camera (Mastcam) to take the images combined into this mosaic of the drill area, called "John Klein." The label "Drill" indicates where the rover ultimately performed its first sample drilling.
The scene was imaged on Sol 166, the 166th Martian day of Curiosity's work on Mars (January 23, 2013). The color has been white-balanced to show what the rocks would like if they were on Earth.
