For example, in analyzing 10,000 images, they found that more holes are produced over the dawn side of the earth than over the dusk side. The down side faces the forward direction of the earth's orbit, so it shoudl sweep up more meteors, "just as a windshield wiper collects more drops in front of it than it does behind," says Sigwarth.
