Charles F Radley - Associate Fellow AIAA

Charles Radley is a spacecraft systems engineer who has worked on manned and unmanned spacecraft development and operations. Professional background includes B.S. Physics, M.S. Systems Engineering, 20+ years aerospace experience. He is an EIT Engineer in Training registered in the State of California, and an Associate Fellow of the American Institute of Aeronautics and Astronautics. In 1981 he started work on communications satellite systems integration, launch campaigns and range safety. Later he was instrumental in developing proposals for lunar space missions for the 1990 Space Exploration Initiative. He was a member of the subcontractor teams for the Galileo and Magellan space probes, the International Space Station, experiments for Spacelab-MSL-1 and several communications satellite projects (e.g. Intelsat-6, Olympus, HS-601, HS-376, Inmarsat-2, Marecs). He worked on the Mobile Transporter, and the power system for NASA Space Station Freedom which became ISS. He is an inter-disciplinary engineer, specializing in systems safety and hazards analysis as well as mission operations. He was principal author of the NASA Guidebook for Safety Critical Software. Was a part time technical consultant for Transorbital Corporation, the first private company licensed by the U.S. government to explore and land on the Moon. He had a key role developing the design and perigee stage for the Trailblazer imaging lunar orbiter for . In 1968 he read about Solar Power Satellites and said ... Yes, this is THE solution. In 1976 he heard about Gerard O'Neill so in 1977 I read the High Frontier, and said, yes, finally a plan which makes sense. For the last 30 years continues to work on the original O'Neill vision with the addition of a lunar elevator. He joined the original L-5 Society in 1979. He was a regional director of the National Space Society (NSS) from 1994-5 and operated an NSS computer bulletin board on fidonet from 1990 through 1992. He has been active in the following NSS Chapters: Ventura County (CA), Cuyahoga Valley Space Society (OH), Oregon-L5; as well as active in the California Space Development Council and Midwest Space Development Corporation. He served a 2- year term as a director of the Moon Society, and later a 2-year term as its Vice President. In 2010 he became Vice President of Leeward Space Foundation, for PR and Programs. He has written extensively on space based solar power, e.g. in the 2009 McGraw-Hill Encyclopedia of Science. He was a contributor to the 2007 Department of Defense study on Space Based Solar Power managed by the National Space Security Office. In 2008 he managed a project by the Moon Society to build a one watt desktop microwave power beaming device and obtained the first ever FCC license for operation of a power beaming device in a public place. He pursues concepts for space manufacturing using lunar resources. He is thoroughly grounded in real world practical spacecraft technology and cost issues, as well as appreciating the big picture long term roadmap for lunar development. In recent years he has been engaged mainly as a software quality engineer in commercial and government IT environments.
