NASA’s Mars rover Curiosity used its front left Hazard-Avoidance Camera for this image of the rover’s arm over the drilling target “Cumberland” during the 275th Martian day, or sol, of the rover’s work on Mars (May 15, 2013).

The rover team plans to use Curiosity’s drill to collect a powdered sample from the interior of the rock for analysis by laboratory instruments inside the rover. This is the mission’s second rock-drilling target. The rover drove from its position beside the first drilling target, “John Klein,” to its position beside Cumberland with drives of 121 inches (308 centimeters) on Sol 273 (May 13) and 26.6 inches (67.5 centimeters) on Sol 275. Curiosity’s total odometry on Mars is now 2,385 feet (727 meters).
