The Curiosity rover has been on Mars since August 2, 2012 and Mars being a dusty place I thought it was time to see how much dust has been accumulating.

An old American penny is part of the calibration target for the Mars Hand Lens Imager (MAHLI) located on a “shoulder joint” of the rover’s arm.

The left hand side is the penny on September 10, 2012 and the one on the right is from October 2, 2013.

Although the accumulation could be worse the target is on a vertical surface.  The pictures prove there is no escaping the dust.

Even the Malin Spaceguy (or spacegal they all look the same to me :mrgreen: ) can’t hide.
