Mission Overview

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)
