Abstract

Space nuclear systems constitute an enabling technology for planetary exploration missions. Long duration power, advanced propulsion, and effective radiation shielding are critical areas that require solutions in order to achieve aggressive robotic and manned space flight missions. Radioisotope systems have traditionally been utilized to provide both power and heat; however, dynamic power conversion and fission systems are under development to enhance and advance options available to mission designers. Collaborative research conducted at various NASA centers and Department of Energy laboratories focus on experimentally based hardware demonstrations to address potential issues associated space nuclear technologies. This paper will discuss the fundamentals of space nuclear systems, their history, and areas where this technology is critical to achieve operations beyond low earth orbit.
