Spirit's specular reflection

When HiRISE took a photo of Spirit's resting spot in Gusev crater on March 31, 2011, it happened to be in exactly the right position to catch a specular reflection (a glint) from the rover's solar panels. Apart from being pretty, it signifies that there was not a thick coating of dust on the panels.
