Inlet Covers for Sample Analysis at Mars

This subframe image from the left Mast Camera (Mastcam) on NASA's Mars rover Curiosity shows the covers in place over two sample inlet funnels of the rover's Sample Analysis at Mars (SAM) instrument suite.

Curiosity delivered SAM's first soil sample on the day this image was taken, the 93rd Martian day, or sol, of the mission (Nov. 9, 2012).
