Abstract

Near-Earth asteroid impact is a major catastrophic threat facing human society. Planetary defense is an inevitable requirement for building a community with a shared future for mankind and continuing human civilization. Implementing on-orbit disposal is the best way to prevent and resolve the risk of near-Earth asteroid impact. This paper systematically combed the development status of near-Earth asteroid defense on-orbit disposal technologies,comprehensively summarized the key technologies,advantages and disadvantages,and application scenarios of nuclear explosion,kinetic impact,gravitational traction,ion beam,laser ablation,tug,mass driver,surface spraying and other on-orbit disposal technologies,and puts forward suggestions for the development of near-Earth asteroid defense on-orbit disposal technology.

Keywords
