Dr. George M. Low, Deputy Administrator of the National Aeronautics and Space Administration, who will make an introductory statement before we hear from Dr. William B. Lenoir, a scientistastronaut assigned to the Astronaut Office at the Johnson Space Center. For the last year, Dr. Lenoir has been serving as the leader of the Satellite Power Systems Team which is supporting NASA's Office of Energy Program's work in that area. Dr. Low and Dr. Lenoir will be accompanied by Mr. Roll D. Ginter, NASA's Acting Assistant Administrator for Energy Programs, and Dr. Christopher C. Kraft, Director of the Johnson Space Center. And since there are no other Senators here for remarks, we will proceed with the first witnesses—Dr. Greenblat, Mr. Fawkes and Dr. Heiss. And I believe Dr. Heiss will have the opening statement. [Biography of Dr. Edward Greenblat follows:] Biography of Dr. Edward J. Greenblat,1 Assistant Vice President, ECON Dr. Greenblat has extensive experience in establishing the economic implications and applications of aerospace and energy technology and has formulated and performed major benefit-cost studies. His work with aerospace technology and policy includes: an analysis of the economic benefits of Earth Resources Observations Satellite applications to water resources management in southern Florida; the development of a methodology for the economic analysis of remote sensing satellite systems to earth resources and environmental control systems; an analysis of the economic benefits that less developed countries might derive from using Earth Resources Technology Satellite imagery; and benefit-cost analysis of Earth Resources Observation Satellite applications to estuarine and coastal management. Other international work that he has done includes an international survey of the potential satellite data collection market. At ECON, Inc., Dr. Greenblat is currently managing a study to do economic analysis of the Satellite Solar Power Station concept, developing economics and system analysis courses for NASA and other R&D centers, participating in earth observations satellite applications studies and concentrating on energy R&D economic studies. Dr. Greenblat participated in the economic analysis of the space shuttle and managed an economic analysis of chemical space tug systems. The most cost- effective investment and scheduling decisions for a choice of expendable and reusable high energy stages for future space activities were identified. As manager of another project, Dr. Greenblat studied the economic characteristics of advanced chemical, nuclear rocket, nuclear electric and solar high energy propulsion systems. TESTIMONY OF DR. KLAUS P. HETSS, PRESIDENT, ECON. INC., PRINCETON, NJ.. AND DR. EDWARD GREENBLAT. ECON, INC., AC COMPANIED BY THOMAS KELLY, VICE PRESIDENT, GRUMMAN AEROSPACE CORP. Dr. Heiss. Thank you, Mr. Chairman. ECON, Inc., jointly with Grumman Aerospace Corp., Arthur D. Little, and Raytheon studied over the past 10 months the one concept—the SSPS concept—that also was testified to, I believe, on Mondav. Senator Ford. Doctor, what is the SSPS concept? Dr. Heiss. The SSPS is the satellite solar power station. Senator Ford. OK. i Ph. D.. Economics, New York University. B.S., Economics, New York University; Rensselaer Polytechnic Institute.
