Curiosity CHIMRA's 150-micrometer sieve, sol 578 In preparation for drilling work at Kimberley, Curiosity "thwacked" its sieve and then visually inspected it.


Compare to this image taken on sol 81.

Possibly problematic


Possibly problematic "edge welds" on the CHIMRA 150-micrometer sieve
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 sieve on an Earth test unit of CHIMRA has suffered popping of its edge welds, which presents the possibility that particles larger than 150 microns in diameter could pass by the sieve.
