The mission, designed and managed by the Johns Hopkins Applied Physics Lab, is the world's first to test technology for defending the planet against potential asteroid or comet hazards
NASA selects Johns Hopkins APL space weather mission for 2024 launch
The Electrojet Zeeman Imaging Explorer will study the auroral electrojet, electrical currents flowing 60-90 miles above the north and south poles By Geoff Brown / Published Jan 8, 2021
A Johns Hopkins Applied Physics Laboratory-led mission to explore electric currents in Earth s atmosphere that link the aurora to our planet s magnetosphere has been selected by NASA to move forward to a scheduled launch in 2024.
The Electrojet Zeeman Imaging Explorer, EZIE, is a set of three small spacecraft 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.
