在黎明计划的1：1共振转换的激励下，本文描述了小行星4灶神星附近近同步轨道及其流形的动力学结构。在表面固定的旋转坐标系中研究了动力学，刻画了表示“地球静止”轨道和近同步平动轨道族的平衡点。由不稳定平动轨道族产生的不变流形结构描述了一种设计跨越1：1共振的弹道转移的途径。提供了在灶神星的1：1共振上的这种传输的例子。
Motivated by the challenging transfer across the 1:1 resonance planned for the Dawn mission, this paper describes the dynamical structure of the near-synchronous orbits and their manifolds near asteroid 4 Vesta. The dynamics are studied in a surface-fixed rotating frame, where equilibrium points representing “geostationary” orbits and near-synchronous libration orbit families are characterized. The invariant manifold structure that arises from the unstable libration orbit families describes a pathway for designing ballistic transfers across the 1:1 resonance. Examples of such transfers across the 1:1 resonance at Vesta are provided.
