摘要
近地小行星撞击是人类社会面临的重大灾难性威胁,实施在轨处置是防范化解近地小行星撞击风险的最佳途径。系统梳理了近地小行星防御在轨处置技术的发展现状,对核爆、动能撞击、引力牵引、离子束偏移、激光烧蚀、拖船、质量驱动、表面喷涂等在轨处置技术的关键技术、优缺点、适用场景等进行了全面综述,提出了近地小行星防御在轨处置技术的发展建议。
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.
