First Image From Curiosity's Arm Camera With Dust Cover Open

The reclosable dust cover on Curiosity's Mars Hand Lens Imager (MAHLI) was opened for the first time during the 33rd Martian day, or sol, of the rover's mission on Mars (Sept. 8, 2012), enabling MAHLI to take this image. 

The level of detail apparent in the image shows that haziness in earlier MAHLI images since landing was due to dust that had settled on the dust cover during the landing.
