One of the most elusive but fascinating movies one could make on Mars today is a time-lapse film of an afternoon dust devil, or miniature tornado. Spirit rover scientists have finally captured a brief animation of such a tiny twister. The interesting weather pattern might give clues to how energy and dust gets moved around on the red planet. It also may account for the sudden boost in solar power as the winds clear dust from the aging panels of the Spirit rover.
