TALK TITLE:     advanced space propulsion concepts for interstellar travel


The presentation begins by examining just a few of the compelling reasons why humans should explore the heavens beyond the bounds of the solar system. Certain terms and issues are defined to clarify the requirements of such daunting journeys. The talk then centers around the key technology required to make such missions possible—propulsion. To start with, a brief discussion is given on the state of the art of in-space chemical propulsion systems to develop a foundation of where engine technology is today. The talk then takes an evolutionary approach by exploring some of the more advanced engine systems intended for long-range solar system exploration, such as nuclear engines, antimatter engines and interstellar ramjets, which define the capability limits of chemical propulsion. After comparing the predicted performance of these advanced concepts to the requirements for interstellar journeys, the focus will then shift to describe a new paradigm of “propellantless” propulsion schemes that have their basis in modern theoretical physics and cosmology. If found attainable, concepts such as space-time manipulation, faster-than-light travel, wormholes, quantum drives, and so on, may provide the only viable propulsion options to enable reasonable trip times to distant stars. To show that these ideas are not merely the dreams of science-fiction, brief descriptions will be given on the latest, global, experimental efforts to explore the fundamentals behind some of these intriguing concepts. The talk will end with some inspiring conclusions and hopefully instill the belief that mankind will someday move beyond the bounds of our solar neighborhood.


Greg Meholic works at The Aerospace Corporation, a federally-funded research and development center located in Los Angeles, California, where he examines future concepts and emerging technology for spacelift systems of interest to the US Government. He also evaluates novel propulsion systems and engine cycles geared towards hypersonics and access to space. He is an expert in liquid rocket engine design and has supported over 40 launches as well as a number of advanced propulsion programs. Greg holds both Bachelors and Masters Degrees in Aerospace Engineering from Embry-Riddle Aeronautical University. His 22 years of aerospace industry experience has given him extensive practical knowledge in aerodynamics, aircraft design, gas turbine and rocket engines and alternative propulsion systems. He is a Distinguished Lecturer and Associate Fellow of the American Institute of Aeronautics and Astronautics and serves on the Nuclear and Future Flight Propulsion Technical Committee. Among his numerous patents and published work in the aerospace field, he has also authored several papers on his own ideas about faster-than-light travel, the construct of space-time, and the grand unified theory. Greg is also an adjunct professor at Loyola-Marymount University instructing courses on Propulsion System Design and is an avid, instrument-rated, private pilot.
