30004 Mikewilliams           Discovered 2000 Jan. 30 by the Catalina Sky Survey.
Mike Williams (b. 1952) was a lead engineer at the University of Arizona's Lunar and Planetary Laboratory. He was instrumental in the design, fabrication and testing of instruments and hardware for ground-based observatories and numerous NASA spacecraft missions to Mars, as well as the OSIRIS-REx asteroid sample return mission.
