This paper explores the feasibility and benefits of a new way of the Phobos sample return delivery mission to a Phobos Sample Return (PSR) orbiter using the electrostatic field artificially generated in proximity to the Mars–Phobos L1 libration point. The proposed method uses the electrostatic interaction to retrieve an orbit sample container (OS) launched from Phobos. This is possibly the first discussion of the mission to deliver Phobos samples to a small area around a PSR orbiter for the subsequent capture of the OS, e.g., using a magnetic trap or net. The feasibility of the proposed retrieval system is discussed from the aspect of local space weather Debye length. The container’s motion is studied, and the conditions of reaching the small given vicinity, the L1 point, are determined. The proposed mission’s principal feasibility is demonstrated. The influence of the electrostatic charge level and the Debye length is studied on the container trajectory and the possibility of capturing the container. In addition, the possible launching points of the container from the Phobos surface and the launching velocity at which the PSR orbiter can capture the container are determined by the backward numerical integration method of the motion equations.

本文探讨了使用火星–霍博斯L1解放点附近人工产生的静电场，将火卫一样品送回火卫一样品返回（PSR）轨道的新方法的可行性和好处。所提出的方法使用静电相互作用来检索从火卫一发射的轨道样品容器（OS）。这可能是关于将火卫一样品运送到PSR轨道器周围的一小块区域以进行随后的OS捕获（例如使用磁阱或网）的任务的第一次讨论。从局部空间天气德拜长度的角度讨论了所提出的检索系统的可行性。研究了容器的运动，并确定了到达小给定区域（L1点）的条件。演示了拟议任务的主要可行性。研究了静电荷水平和德拜长度对容器轨迹的影响以及捕获容器的可能性。此外，还可以通过运动方程的后向数值积分方法来确定容器从火卫一表面的可能发射点以及PSR轨道器捕获容器的发射速度。
