- Abstract
Since the dawn of the space age nearly fifty years ago, the United States has pursued a variety of methods for delivering electrical power to spacecraft in flight. Nuclear power systems are the only ones that have been found acceptable for deep space missions. While these technological systems made possible a myriad of accomplishments in space, especially the successful flights to the outer planets, the details of space nuclear power generation is virtually unknown to even the most knowledgeable observers. What is known, furthermore, is often limited to the often incomplete reporting of controversies over the propriety of using nuclear systems for space power. This paper will trace the development of this technology from its origins in the 1960s to the present. It will describe the evolution of the systems involved and the decision-making process whereby NASA chose to adopt one approach over another. Finally, it will analyze the public debate over the employment of these technologies for spaceflight.
