Erik Asphaug is the Ronald Greeley Chair of Planetary Science at ASU. His research into the physical and geological properties of asteroids and comets has been the subject of numerous review chapters and ongoing publications. He participated in the Galileo and LCROSS missions, and is PI of a team whose proposed mission, Comet Radar Explorer, seeks to map, in high resolution 3D, the internal structure of a comet. Other research includes the origin of planets and moons, the origin of patterns on the surface of Mars, and impact cratering and its effects at large and small scales. He is also working on the development of a cubesat-based approach to microgravity research relevant to asteroid and comet geophysics and NEO resource utilization. He is recipient of the 1998 Urey Prize of the Division of Planetary Sciences of the DPS, and asteroid 7939 Asphaug is named to recognize his research into the origin and evolution of primitive bodies.
