The Energy Research and Development Administration and the National Aeronautics and Space Administration have signed an interagency agreement in which ERDA and NASA management will identify specific program tasks that can be undertaken by the NASA centers in support of ERDA programs. ERDA will use the NASA centers in three broad areas:▸ Research in specified fields such as solar systems, gas turbines, fuel cells, hydrogen technology and ground‐propulsion technology;▸ Proposals for specific technology developments, including testing, evaluation and demonstration of projects or hardware;▸ ERDA may call upon NASA for technical and administrative expertise in ERDA's management arrangements with private high‐technology institutions.
