Shown in this artist’s concept, Southwest Research Institute managed NASA’s Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites (TRACERS) mission, which has entered its final integration phase. In addition to providing mission management and science services to NASA and the University of Iowa, SwRI developed the Analyzer for Cusp Ions (ACI) instruments, which will study how the magnetic fields of the Sun and the Earth interact through novel measurements in the polar cusps.
