COLLOQUIUM: Fusion Rockets for Planetary Defense

Dr. Glen Wurden
Los Alamos National Laboratory

Fusion rocket engines could enable a rapid response capability for deflecting an incoming comet, to prevent its impact on the planet Earth, in defense of our population, infrastructure, and civilization. The problem with long period comets is that they basically arrive to the inner solar system unannounced. If one were on a collision course with Earth, we would only have 6-18 months of warning. To make a long-distance deflection of the comet, with momentum change delivered by ablation caused by radiation from a stand-off nuclear explosive, you need a fly-by interceptor rocket with 20-40x the performance of our best existing chemical rockets. A fusion rocket engine could enable the mission. Interestingly, the performance metrics and design constraints for a fusion rockets are quite different than for our usual Demo fusion reactor.
