Martians Use Their Squeegees Again

Spirit Gets A Dust Devil Once-Over

The Spirit rover on Mars was losing most of the power it was getting from its solar panels. It was down by 40%. But fortunately, the martians have squeegees. Someone there dusted off the panels, and they're all clean again.

How many times can we count on the martians to wipe down our rovers? We didn't send any cash with them. Also, we don't know what martians use as cash, so we can't send it along on the next trip, either.

Maybe they're just being neighborly. Mars IS only 64 milliion miles from here. They probably figure that if they're nice, and show us how to be good neighbors, then we won't leave behind tons of our castoff junk, like we did on the moon.
