Electrojet Zeeman Imaging Explorer (EZIE), A NASA Mission of Opportunity to study the ionospheric electrojets

The Electrojet Zeeman Imaging Explorer (EZIE) is a set of three SmallSats that will study the auroral electrojet, which are electrical currents flowing about 60 to 90 miles above the poles that link the beautiful aurora to the Earth’s magnetosphere, and which responds to solar activity and other drivers.
