Our solar system readily provides us with free samples of other worlds in the form of meteorites. The trick comes in first recognizing them, and then in understanding what science is locked in their minerals. One major center for collecting and studying these space rocks is Arizona State University's Buseck Center for Meteorite Studies which houses the Carleton B Moore Meteorite Collection. Join us as we discuss the collection with Director Rhonda Stroud.
