命运+是一个即将到来的JAXA Epperium中型使命飞行的双子座流星雨母体（3200）法厄同。它将是世界上第一个使用小推力推进系统从近地球静止转移轨道逃逸到深空的航天器。在此过程中，DESTINY+将展示一系列技术，包括高效的离子发动机系统、轻型太阳能电池阵列板和先进的小行星飞越观测仪器。这些演示将为JAXA设想的低成本、高频率太空探索计划铺平道路。在法厄同飞越观测之后，“命运+”将作为其延长的使命访问更多的小行星。使命设计分为三个阶段：螺旋形远地点上升阶段，多月球飞越阶段逃离地球，行星际和小行星飞越阶段。主要挑战包括在操作限制下优化多转低推力螺旋阶段;设计多体环境中的多月球飞越序列;以及设计通过地球重力辅助连接的多个小行星飞越。本文展示了一种新颖的，实用的方法来解决这些复杂的问题，并提出了可行的解决方案，在大规模预算和使命的限制。其中，基线解决方案进行了展示和深入讨论; DESTINY+将花费两年时间用离子发动机提高其远地点，随后进行四次月球重力辅助，并飞越小行星（3200）Phaethon和（155140）2005 UD。最后，详细介绍了螺旋飞行阶段和小行星飞越阶段的飞行操作计划。
DESTINY+ is an upcoming JAXA Epsilon medium-class mission to fly by the Geminids meteor shower parent body (3200) Phaethon. It will be the world’s first spacecraft to escape from a near-geostationary transfer orbit into deep space using a low-thrust propulsion system. In doing so, DESTINY+ will demonstrate a number of technologies that include a highly efficient ion engine system, lightweight solar array panels, and advanced asteroid flyby observation instruments. These demonstrations will pave the way for JAXA’s envisioned low-cost, high-frequency space exploration plans. Following the Phaethon flyby observation, DESTINY+ will visit additional asteroids as its extended mission. The mission design is divided into three phases: a spiral-shaped apogee-raising phase, a multi-lunar-flyby phase to escape Earth, and an interplanetary and asteroids flyby phase. The main challenges include the optimization of the many-revolution low-thrust spiral phase under operational constraints; the design of a multi-lunar-flyby sequence in a multi-body environment; and the design of multiple asteroid flybys connected via Earth gravity assists. This paper shows a novel, practical approach to tackle these complex problems, and presents feasible solutions found within the mass budget and mission constraints. Among them, the baseline solution is shown and discussed in depth; DESTINY+ will spend two years raising its apogee with ion engines, followed by four lunar gravity assists, and a flyby of asteroids (3200) Phaethon and (155140) 2005 UD. Finally, the flight operations plan for the spiral phase and the asteroid flyby phase are presented in detail.
