Well, there's never been a good explanation about how the rover solar panels kept putting out juice and didn't get covered with dust.

The explanation is: Winds occasionally blow off the dust accumulations.

Winds occasionally blow off the dust accumulations.

Art Bell had Jim Bell (Cornell prof, leader of the rovers' pancam team) on a week or so ago, and I was so disappointed
in his contradictory answers to separate, but related questions: Wind blows off the dust, but the atmosphere was
considered too thin to add a microphone to either/both of the rovers, etc.
