Marc G. Millis

Marc Millis is a leading international authority on the search for breakthrough spaceflight – the kind of breakthroughs that would make interstellar voyages practical. Marc recently retired from NASA where he once led the Breakthrough Propulsion Physics Project. He has also forged a collaboration of over 3-dozen scientists, engineers, writers, and educators to create the Tau Zero Foundation – a nonprofit organization devoted to accelerating progress and providing public education toward practical interstellar flight. Millis earned a Bachelor of Science in Physics from Georgia Tech (1982), a Masters of Science in Physics Entrepreneurship from Case Western Reserve University (2006), and is an alumnus of the International Space University Summer Session (1998). He has produced over 40 technical and management papers, and recently completed – as lead editor and a contributing author – the book, Frontiers of Propulsion Science (AIAA, 2009). This is the first scholarly book covering such edgy topics as gravity-control space drives and faster-than-light travel. Also to his credit is an award-winning website ("Warp Drive, When?"), and the chapter: "Making the jump to light-speed" in the National Geographic book: Star Wars - Where Science Meets Imagination (2005). This chapter illustrates how genuine scientific questions can be extracted by playing with science fiction. His breakthrough-seeking work gets wide public attention, being cited in Newsweek, Wired, Popular Science (May 2001 cover), New York Times and in the books Centauri Dreams (Gilster 2004) and in I'm Working On That (Shatner & Walter 2002). His visionary work also earned Millis a nomination for a 2004 World Technology Award. In addition to propulsion physics, Millis has designed ion thrusters, electronics for rocket monitoring, cryogenic propellant equipment, and even a cockpit display to guide free-fall aircraft flights. In his free time, Millis enjoys craftsmanship; building award-winning scale models, Halloween costumes, and other mischief. With specialties in science fiction models built from scrap plastic and 1960's slot cars, he occasionally publishes how-to articles and photographs. Amidst all of this, Millis enjoys time as a husband and father.
