The invention relates to the technical field of space debris protection, in particular to an accompanying guard moonlet and spacecraft operation system which comprises a first-stage cabin, a second-stage cabin, a third-stage cabin, a first-stage protection assembly, a second-stage protection assembly, a third-stage protection assembly and a fourth-stage protection assembly. And the utilization degree of the accompanying guard moonlet is improved. When space debris with the size of 1-10 cm comes, the second-level cabin body stretches out of a third containing cavity of the first-level cabin body, the third-level cabin body stretches out of a fifth containing cavity of the second-level cabin body, the first-level protection assembly stretches out of a first containing cavity after being unfolded, the second-level protection assembly stretches out of a second containing cavity after being unfolded, and the third-level protection assembly stretches out of a fourth containing cavity after being unfolded. And the fourth-stage protection assembly is unfolded to extend out of a sixth containing cavity, a multi-stage defense barrier is formed, the multi-stage interception effect on space debris with the size being 1 cm to 10 cm is achieved, the space debris is broken to the maximum extent, and kinetic energy of the space debris is dissipated.

    本发明涉及空间碎片防护技术领域,尤其涉及一种伴飞护卫小卫星及航天器运行系统,包括一级舱体、二级舱体、三级舱体、一级防护组件、二级防护组件、三级防护组件和四级防护组件,既能执行巡检任务,又执行防护任务,提高了对伴飞护卫小卫星的利用程度。当有尺寸为1cm‑10cm的空间碎片来袭时,二级舱体探出一级舱体的第三容纳腔,三级舱体探出二级舱体的第五容纳腔,一级防护组件展开探出第一容纳腔,二级防护组件展开探出第二容纳腔,三级防护组件展开探出第四容纳腔,四级防护组件展开探出第六容纳腔,构成多级防御屏障,对尺寸为1cm‑10cm的空间碎片起到多级拦截作用,最大程度地使空间碎片破碎,并使空间碎片的动能耗散。
