摘要：在推断小行星和彗星结构特性的背景下，讨论了旋转激励和阻尼。概述了进行确定性实验的机会，并讨论了涉及空间任务的基本概念。携带着陆器或炸药的航天器连同轨道器被认为是小行星和彗星内部的有效探测器。这些任务的可行性，特别是对近地天体（neo）的可行性，被强调为近地天体提供了探索小行星和彗星内部的合适的成本效益路径。
Abstract— Rotational excitation and damping are discussed in the context of inferring structural properties of asteroids and comets. Opportunities for carrying out deterministic experiments are outlined and basic concepts involving space missions are discussed. Spacecraft carrying an impactor or explosives together with an orbiter are suggested as effective probes of the interiors of asteroid and comets. The feasibility of such missions, especially to near‐Earth objects (NEOs), is highlighted as NEOs provide an appropriate cost‐effective path to explore interiors of asteroids and comets.
