Spirit rover despite being pretty much stuck ankle deep in the Mars soil, is still busy looking around at it's surroundings. Some new dust devil images have been released including one that is about 1,350 feet across! Despite the hugeness of this thing, due to the thin atmosphere, the rover isn't in any danger of being sucked away to the land of Oz and scary flying monkeys. It would most likely give the solar panels a good cleaning of the dust that falls on them. These devils are what have been keeping the rovers going with their occasional cleaning.
But if this was on Earth, and this was a tornado rather than a dust devil (big difference), you know this would be headed directly toward the nearest trailer park or farmhouse!
