Expected to measure the albedos and diameters of over 100,000 asteroids, the Wide-field Infrared Survey Explorer spacecraft (WISE) will provide the most detailed look yet at the distributions of asteroid sizes in the Main Belt and inner Solar System, a property which traces the formation and collisional history of both populations. The albedo of an asteroid is a direct result of the surface composition and chemistry, and the WISE albedos will be able to trace compositional gradients as a function of both size and location in the Solar System, and thus the Sun's protoplanetary disk. Additionally, the serendipitous measurements of new classes of objects (e.g. Main Belt comets) or unusual transients (e.g. long period comets) will provide new windows into the structure, properties, formation and evolution of these bodies. We present a survey of the asteroid science planned for WISE, slated to run from Dec 2009 to Aug 2010.
