Electrojet Zeeman Imaging Explorer (EZIE) is a planned NASA heliophysics mission, that will study the Sun and space weather near Earth. It will consist of three CubeSats that will study the auroral electrojets, "by exploring a phenomenon called Zeeman splitting, which is the splitting of a molecule’s light spectrum when placed near a magnetic field".[1] EZIE is expected to be launched in 2025.[2]
