Solid-core reactor has reached prototype engine demonstration after decade of development; review describes major characteristics of solid-core nuclear rocket engines, to indicate their state of development and probable application, and to discuss variety of advanced concepts for high-thrust propulsion systems; hydrogen which has molecular weight one-fourth that of chemical-propellant exhaust products enables exhaust to be doubled, and payload, which depends exponentially upon exhaust velocity, can be increased manyfold; payload advantage becomes more significant as mission energy requirements are increased, because nuclear-propelled vehicles require less gross weight and fewer stages than equivalent chemical rockets.
