This cutaway view shows the internal chambers of the Collection and Handling for In-Situ Martian Rock Analysis (CHIMRA) device, attached to the turret at the end of the robotic arm on NASA's Curiosity Mars rover. Samples from the drill enter via the sample transfer tube, and samples from the scoop enter from the location shown at bottom. The pink line shows the path samples travel from the scoop (red) to the 150-micrometer sieve (green rectangle) to the portion box (yellow), where they are then delivered to the analytical lab instruments.

JPL manages the Mars Science Laboratory/Curiosity for NASA's Science Mission Directorate in Washington. The rover was designed, developed and assembled at JPL, a division of the California Institute of Technology in Pasadena.
