Abstract

The first step of any active debris removal (ADR) mission is the selection of the target. The optimal choice is to find the most dangerous debris that can be removed considering the chaser spacecraft requirements and mission constraints. After creating a catalog of the current space population in low Earth orbit (LEO), the MIT Monte Carlo Orbital Capacity Assessment Tool (MOCAT-MC) is used to simulate and predict the future space environment and the interaction among the space population. A novel performance index to quantify the criticality of each debris and the risk that it presents to the space environment is proposed. The new risk index considers the proximity of the debris to highly populated regions, its persistence in orbit, its likelihood to collide, and the estimated number and mass of debris that it can generate. The risk index is then optimized to work either with the full space population or a subset of it, where the ranking of risk among debris is highlighted. Multiple risk analyses are proposed in the test cases, where the ranked list of optimal targets is provided.

主动碎片清除目标最优排序的风险指数

主动碎片清除(ADR)任务的第一步是目标的选择。考虑到追踪器的要求和任务限制，最优的选择是找到最危险的碎片。在创建当前近地轨道空间人口目录后，利用麻省理工学院蒙特卡罗轨道容量评估工具(MOCAT-MC)对未来空间环境和空间人口之间的相互作用进行模拟和预测。提出了一种新的性能指标来量化每个碎片的临界性及其对空间环境造成的风险。新的风险指数考虑了碎片与人口密集地区的接近程度、在轨道上的持久性、碰撞的可能性以及可能产生的碎片的估计数量和质量。然后对风险指数进行优化，以适用于整个空间人口或其中的一个子集，其中突出显示碎片之间的风险排名。在测试用例中提出了多个风险分析，并给出了最优目标的排序列表。
