Earth-Impact Modeling and Analysis of a Near-Earth Object Fragmented and Dispersed by Nuclear Subsurface Explosions
Bong Wie, Iowa State University, David Dearborn, Lawrence Livermore National Laboratory
This paper describes the orbital dispersion modeling, analysis and simulation of a near-Earth object (NEO) fragmented and dispersed by nuclear subsurface explosions. It is shown that various fundamental approaches of Keplerian orbital dynamics can be effectively used for the orbital dispersion analysis of fragmented NEOs. It is also shown that under certain conditions, proper disruption (i.e., fragmentation and large dispersion) using a nuclear subsurface explosion even with shallow burial (< 5 m) is a feasible strategy providing considerable mitigation if all other approaches failed.
