EZIE: The Mission to Explore Earth's Link to Space

Developed and led for NASA by the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, EZIE is a mission to explore Earth’s electrojets - intense electric currents flowing high above Earth’s polar regions and the dayside equatorial region. EZIE will provide unprecedented measurements of these electrical currents to answer decades-old - and much debated - mysteries. Understanding these currents is key to scientists’ ability to develop capabilities for predicting hazardous space weather.
