> I realized that we already have a ton of asteroid material on earth. The quantity isn't as high as you might expect. Most meteor flux is from cometary dust, not asteroids. The Geminids and Taurids are asteroid in origin but no meteorites have been traced to those showers. Once the atmosphere and oceans take care of the majority, only about 10 meteorites of asteroid origin are recoverable each year.
