Kleopatra is an M-type asteroid rich in metal; such asteroids have been difficult to study or image. In a Perspective Hartmann discusses the new radar observations of this asteroid reported by Ostro et al. in this issue and their conclusions that this asteroid is composed of a loose assemblage of metal grains forming an overall dumbell shape. Such a collection of metal grains in an asteroid might be ammenable to mining in space, that is, an asteroid opportunity rather than a hazard.
