Data revealed from three small satellites make up NASA’s mission EZIE (Electrojet Zeeman Imaging Explorer) to unravel the mysteries in the surroundings of the auroral electrojet. Launched from California on March 14, 2025, the three satellites of NASA’s EZIE mission have officially begun their journey above the Earth’s atmosphere. The early observations coming in are already proving to be incredibly valuable in helping scientists better understand Earth’s auroral electrojets, they say. NASA says this is the first mission to study this electrical current in both northern and southern polar regions. Study of EZIE Mission After the launch of NASA’s EZIE Mission, these three CubeSats are now orbiting in a pearl-on-a-string form, 260 to 370 miles high from the Earth’s surface, to map the auroral electrojets. The EZIE team is excited to see the first light results, said the leader of the team, Sam Yee, of the Johns Hopkins Applied Physics Laboratory. Observations revealed it is clear that the spacecraft and the MEM instrument are both working as per the expectations. What is MEM? It is …
