Uploader comment: The bit in the rotary-percussion drill of NASA's Mars rover Curiosity left its mark in a target patch of rock called "John Klein" during a test on the rover's 176th Martian day, or sol (February 2, 2013), in preparation for the first drilling of a rock by the rover.
The Sol 176 test, called the "drill on rock checkout," used only the hammering or percussive action of the drill, not rotary action.
