WILLIAM W. HOOVER, Co-Chair, is a consultant for aviation, defense, and energy matters. He is a former Assistant Secretary, Defense Programs, U.S. Department of Energy, where he was responsible for the U.S. nuclear weapons development program, including production, research, testing, safety, and security. He is also a Major General, USAF (retired), and a former chair of the NRC’s Aeronautics and Space Engineering Board.


RALPH L. McNUTT, JR., Co-Chair, is a senior space physicist at the Johns Hopkins University Applied Physics Laboratory. Dr. McNutt is currently the Project Scientist and a Co-Investigator on the MESSENGER Discovery mission to Mercury, a Co-Investigator on the New Horizons mission to Pluto, and a Co-Investigator on the Voyager Plasma Science (PLS) and Low-Energy Charged Particles (LECP) experiments. He is also a member of the Ion Neutral Mass Spectrometer Team for the Cassini Orbiter spacecraft. He has worked on the physics of the magnetospheres of the outer planets, the outer heliosphere (including solar wind dynamics and properties of VLF radiation), Pluto’s atmosphere, pulsars, high current electron beams, the physics of active experiments in the mesosphere/thermosphere (artificial aurora), and the solar neutrino problem. Dr. McNutt previously served as a member of the NRC Committee for the Study of the Next Decadal Mars Architecture (2006), the Committee on Priorities for Space Science Enabled by Nuclear Power and Propulsion: A Vision for Beyond 2015 (2004-2006), the Committee to Assess Solar System Exploration (2007-2008), and the Committee to Review New Opportunities in Solar System Exploration (2007-2008).


DOUGLAS M. ALLEN, the General Manager of Schafer Corporation’s Dayton operations, has 28 years experience in aerospace technology, with an emphasis on space power technology. He formerly was the program manager of nuclear power system development for SDIO (now the Missile Defense Agency), including the SP-100 and Topaz programs. He served as a member of NASA’s Lunar Surface Fission Power System Study in support of the Exploration Systems Architecture Study (ESAS) in 2005, as a member of NASA’s Nuclear Strategic Roadmap committee in 2004-2005, and as a member of an NRC thermionics study committee in 2000. He was awarded AIAA’s Aerospace Power Systems Award for career achievements in space power in 2008.


SAMIM ANGHAIE is a professor of nuclear and radiological engineering at the University of Florida, where he also is director of the Innovative Nuclear Space Power and Propulsion Institute (INSPI). He has been a professor at Florida since 1986, before which he was an assistant professor at Oregon State University for two years. His research interests include thermal hydraulics, computational fluid dynamics and heat transfer, high temperature nuclear fuels and materials, inverse radiation transport methods, advanced reactor design, direct energy conversion, and space nuclear power and propulsion.


RETA F. BEEBE is a professor in the Astronomy Department at New Mexico State University. She is a leading expert in the study of the atmospheres of Jupiter and Saturn, and in particular, studies of cloud motion and development in Jupiter’s atmosphere. She undertakes her studies using a variety of techniques including ground- and space-based telescopic observations and remote-sensing studies using spacecraft. Most recently, she has served as an associate member of the Galileo imaging team and has led the team of astronomers using the Hubble Space Telescope to provide context images for the Galileo project. Dr. Beebe currently serves as the program scientist for the Planetary Data System (PDS). Dr. Beebe has also been extensively involved in the management and implementation of the research and analysis programs that provide basic research funding to planetary scientists.
