ABSTRACT
Future space technologies could be viewed from those organizations that are in the forefront of space technologies. National Aeronautics and Space Administration (NASA) developed the set of draft roadmaps for use by the National Research Council as an initial point of departure for mapping NASA’s future investments in technology. For solar power satellites to become economically feasible there is need for a low-cost space transport, and for solar power satellite (SPS) to be successful, there is a need for an organized industry and a viable approach for SPS implementation. SPSs are to be placed in low Earth orbit from which they will transmit the collected solar energy back to Earth by microwave transmission. International involvement of United Nations member countries who are also members of International Telecommunications Union is mandatory for coordinating global treaties and agreements, frequency assignments, satellite orbital locations, space traffic control, and other activities to prevent any potential radio interference into their domestic communication systems and services.
