Asphaug was involved in NASA's Galileo and LCROSS missions. He is currently a principal advocate of a mission strategy to obtain a medical-like scan of the detailed interior structure of a Jupiter-family comet, which would reveal its origin, evolution and structure using techniques of 3D radar imaging and tomography.
