The sieve screen, used for sifting rock samples after drilling, is seen here on NASA's Mars rover Curiosity and is used to remove the larger particles from samples before delivery to the analysis instruments.
The 150-micrometer sieve is part of the Collection and Handling for In-situ Martian Rock Analysis (CHIMRA) hardware at the end of Curiosity's arm.
