Animation of EZIE Satellites Orbiting Above Earth's Aurora (VIDEO)

Caption

NASA’s EZIE (Electrojet Zeeman Imaging Explorer) mission will use three CubeSats to map Earth’s auroral electrojets — intense electric currents that flow high above Earth’s polar regions when auroras glow in the sky. As the trio orbits Earth, each satellite will use four dishes pointed at different angles to measure magnetic fields created by the electrojets.
