The detailed study of the global characteristics of collisionless magnetic reconnection that occurs at the magnetopause will be greatly enhanced by observations of plasma fluxes and fields within the low-altitude cusp region, as sampled by two spacecraft orbiting in tandem. The NASA Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites (TRACERS) mission, a Heliophysics Small Explorer (SMEX) mission, will provide the necessary observations to enable significant progress to be made on understanding magnetic reconnection, especially in terms of its temporal versus spatial characteristics. This paper provides an overview of the TRACERS mission design and the trade studies conducted for the optimization of this design.
通过两颗串联轨道运行的航天器对低高度磁尖区等离子体通量和磁场的观测,将极大地促进对磁层顶无碰撞磁重联全球特性的详细研究。美国国家航空航天局的串联重联与磁尖电动力学探测卫星(TRACERS)任务是一项日球物理小型探索者(SMEX)任务,它将提供必要的观测数据,以便在理解磁重联方面取得重大进展,特别是在其时间与空间特性方面。本文概述了TRACERS任务设计以及为优化该设计而进行的权衡研究。
