The mission studies substorms--sudden energy releases in the magnetosphere--and processes like magnetic reconnection and plasma waves. that magnetotail reconnection triggers substorms, improving understanding of space weather and its impacts on satellites, communication systems. The mission contributes to heliophysics by exploring Earth’s magnetosphere dynamics. Its primary goal was to study auroras and their connection to energy releases in the magnetosphere.
