Landing on the surfaces of small solar system bodies (3SBs) is a prerequisite for maximizing the value of probes and provides technical reserves for the resource development of 3SBs and crewed landings on their surfaces. Motivated by the purposes of space exploration, such as finding the origin of life and developing space resources, launching probes and landing them on 3SBs is attracting increasing attention. The microgravitational environment and uncertain surface characteristics on 3SBs will contribute to the rebounding and tipping over of probes and thus pose great challenges to the landing of probes. In this paper, global deep space missions and plans to explore 3SBs are summarized, and the technologies related to landing mechanisms and sampling-cushioning assemblies are organized. The surface characteristics of 3SBs are important factors affecting the landing process of probes, so the achievements of the surface characteristics that have been obtained by scientific observations are reviewed, and theoretical research on mechanical properties is discussed. For more experience in the landing-cushioning of space probes, the existing landing structures and cushioning assemblies adopted for missions to other extraterrestrial bodies are studied, then their characteristics are analyzed and several novel approaches for landing on 3SBs are proposed. Subsequently, the microgravitational landing experiments and realization methods are sorted. Finally, some discussion about the future development of landing on 3SBs is presented.

探索小型太阳系天体的着陆机制的技术进步

小型太阳能系统主体(3SB)的表面着陆是使探测器价值最大化的先决条件,并为3SB的资源开发及其表面的人员着陆提供了技术储备。出于探索太空目的的动机,例如寻找生命的起源和开发太空资源,发射探测器并将其降落在3SB上,这引起了越来越多的关注。3SB上的微重力环境和不确定的表面特性将导致探针的反弹和倾覆,因此对探针着陆提出了巨大挑战。本文总结了全球深空任务和探索3SB的计划,并组织了与着陆机制和采样缓冲组件相关的技术。3SBs的表面特性是影响探针着陆过程的重要因素,因此,对通过科学观察获得的表面特性的研究成果进行了综述,并讨论了力学性能的理论研究。为了获得更多空间探测器着陆缓冲的经验,研究了现有的着陆结构和用于向其他外星体执行任务的缓冲组件,然后分析了它们的特性,并提出了几种新颖的登陆3SB的方法。随后,对微重力着陆实验和实现方法进行了分类。最后,提出了有关登陆3SB的未来发展的一些讨论。因此,回顾了通过科学观察获得的表面特性的研究成果,并讨论了力学性能的理论研究。为了获得更多空间探测器着陆缓冲的经验,研究了现有的着陆结构和用于向其他外星体执行任务的缓冲组件,然后分析了它们的特性,并提出了几种新颖的登陆3SB的方法。随后,对微重力着陆实验和实现方法进行了分类。最后,提出了有关登陆3SB的未来发展的一些讨论。因此,回顾了通过科学观察获得的表面特性的研究成果,并讨论了力学性能的理论研究。为了获得更多空间探测器着陆缓冲的经验,研究了现有的着陆结构和用于向其他外星体执行任务的缓冲组件,然后分析了它们的特性,并提出了几种新颖的登陆3SB的方法。随后,对微重力着陆实验和实现方法进行了分类。最后,提出了有关登陆3SB的未来发展的一些讨论。研究了现有的着陆结构和用于其他外星人飞行任务的缓冲组件,然后分析了它们的特性,并提出了几种新颖的登陆3SB的方法。随后,对微重力着陆实验和实现方法进行了分类。最后,提出了有关登陆3SB的未来发展的一些讨论。研究了现有的着陆结构和用于其他外星人飞行任务的缓冲组件,然后分析了它们的特性,并提出了几种新颖的登陆3SB的方法。随后,对微重力着陆实验和实现方法进行了分类。最后,提出了有关登陆3SB的未来发展的一些讨论。
