This image shows the location of the 150-micrometer sieve screen on NASA's Mars rover Curiosity, a device used to remove larger particles from samples before delivery to science instruments. The sieve lies within the Collection and Handling for In-situ Martian Rock Analysis (CHIMRA) structure, which is on the end of the rover's turret, or arm.
This picture was taken by the rover's Mast Camera on Sol 81, the 81st Martian day of the mission (October 28th 2012). The color has been white-balanced to show the scene as it would appear on Earth.
Malin Space Science Systems, San Diego, developed, built and operates Mastcam. NASA's Jet Propulsion Laboratory, Pasadena, Calif., manages the Mars Science Laboratory Project and the mission's Curiosity rover for NASA's Science Mission Directorate in Washington. The rover was designed and assembled at JPL, a division of the California Institute of Technology in Pasadena.
