The small arm picks up and moves new sample tubes to the drill, and transfers filled sample containers into a space where they are sealed and stored. While the rover’s big arm reaches out and drills rock, the rover belly is home to a small robotic arm that works as a "lab assistant" to the big arm. Next to that are the 43 sample tubes waiting to be filled. It contains a rotating drill carousel, which is a wheel that contains different kinds of drill bits. The belly of the rover houses all the equipment and supplies needed to collect samples. Detailed maps will be provided for any future mission that might go to Mars and pick up these samples for study by scientists. These samples will be sealed in tubes and left in a well-identified place, or more than one spot, on the surface of Mars. A big job for the rover is collecting carefully selected samples of Mars rock and soil.
