摘要：

During the past two decades, various options such as nuclear explosions, kinetic impactors, and slow-pull gravity tractors have been proposed for mitigating the impact threat of near-Earth objects (NEOs). However, currently, there is no consensus on how to reliably deflect or disrupt hazardous NEOs in a timely manner. The use of nuclear explosives may become inevitable for the most probable impact threat with a short warning time. This paper presents potential NEO candidates selected for a planetary defense technology (PDT) demonstration mission, currently being envisioned by the planetary defense community. A flight demonstration mission is necessary to validate and verify the practical effectiveness of blending a hypervelocity kinetic impactor with a penetrated nuclear subsurface explosion.
