Putting the tools to work

This high-res image from the Navigation Camera on the Curiosity rover shows the turret of tools at the end of the rover's arm, as seen on August 20, 2012.

Tools at the end of the robotic arm include the X-ray spectrometer (APXS), the Mars Hand Lens Imager (MAHLI camera), and the Collection and Handling for In-situ Martian Rock Analysis (CHIMRA) which includes a drill and two spare bits, a brush, soil scoops, and the 150-micrometer seive.
