任务简介

NASA的串联重联与极尖电磁动力学侦察卫星（TRACERS）任务由两颗相同的卫星组成，它们将串联绕地球运行（一颗跟随另一颗），旨在帮助理解磁重联及其对地球大气的影响。当太阳活动与地球磁场相互作用时，就会发生磁重联。通过理解这一过程，科学家将能够更好地理解和应对太阳活动对地球的影响。 搭载的小型卫星： * 雅典娜EPIC（经济有效载荷集成成本） * 多语言实验终端（PExT） * 相对论电子大气损失（REAL）

NASA's Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites (TRACERS) mission, consisting of two identical satellites that will orbit Earth in tandem (one following the other), will help understand magnetic re-connection and its effects in Earth’s atmosphere. Magnetic re-connection occurs when activity from the Sun interacts with Earth’s magnetic field. By understanding this process, scientists will be able to better understand and prepare for impacts of solar activity on Earth. Hitchhiking small satellites: * Athena EPIC (Economical Payload Integration Cost) * Polylingual Experimental Terminal (PExT) * Relativistic Electron Atmospheric Loss (REAL)
