论文摘要
这项工作提出了一个轨道内粒子收集的任务概念，用于对近地小行星进行采样和探索任务。通过小的动力学撞击器生成弹射器，并研究了两种可能的收集策略：沿着反 - 极方向收集粒子，利用l $ _2 $ lagrangian点的动力学特征，或在小行星旋转小行星和小行星重新撞击小星际表面时收集它们。通过评估通过评估粒子收集的潜力，将颗粒的动力学结合在太阳辐射压力的圆形限制的三体问题与弹射器生成模型扰动的三体问题。
This work presents a mission concept for in-orbit particle collection for sampling and exploration missions towards Near-Earth asteroids. Ejecta is generated via a small kinetic impactor and two possible collection strategies are investigated: collecting the particle along the anti-solar direction, exploiting the dynamical features of the L$_2$ Lagrangian point or collecting them while the spacecraft orbits the asteroid and before they re-impact onto the asteroid surface. Combining the dynamics of the particles in the Circular Restricted Three-Body Problem perturbed by Solar Radiation Pressure with models for the ejecta generation, we identify possible target asteroids as a function of their physical properties, by evaluating the potential for particle collection.
