This March, NASA's Electrojet Zeeman Image Explorer (EZIE) trio of solar-powered CubeSats will soar above Earth’s electrojets, which flow just 60 miles above the surface. Designed and built by Johns Hopkins APL, each CubeSat carries a Microwave Electrojet Magnetogram (MEM) instrument that exploits the Zeeman effect—the splitting of spectral lines from thermal radiation emitted by oxygen in the ionosphere—to map Earth’s magnetic field and electric currents, producing unprecedented 2D maps of the electrojets’ distribution across 90-300 miles from 50 miles above Earth’s surface.
