A faint shooting star or meteor streaking across the sky is produced when a tiny bit of rock or dust enters the Earth's atmosphere and burns up some 60 miles above us. NASA scientist Dr. Marc Fries and his collaborators have used Doppler Weather Radar to track twenty meteor's dark trails through the sky. In the past year or so they have used this technique to direct searchers on the ground to the probable location of freshly fallen meteorites.
