Martian janitors....

... are apparently boosting solar panel energy output for one of the Mars rovers.

"...something -- or someone -- had regularly cleaned layers of dust from the solar panels of the Mars Opportunity vehicle while it was closed down during the Martian night. The cleaning had boosted the panels' power output close to their maximum 900 watt-hours per day after at one stage dropping to 500 watt-hours because of the heavy Martian dirt. "
