EXECUTIVE SUMMARY

NASA’s Space Technology Mission Directorate requested the National Academies of Sciences, Engineering, and Medicine to convene an ad hoc committee to identify primary technical and programmatic challenges, merits, and risks for developing and demonstrating space nuclear propulsion technologies of interest to future exploration missions. The particular systems of interest were specified as nuclear thermal propulsion and nuclear electric propulsion systems. The committee was also tasked with determining the key milestones, a top-level development and demonstration roadmap, and other missions that could be enabled by successful development of these systems.
