NASA launches EZIE mission to study Earth's electrojets

phys.org

NASA's EZIE mission launched on March 14, 2025, from Vandenberg Space Force Base, California. The mission uses three small satellites to study auroral electrojets, electric currents in Earth's upper atmosphere, at altitudes of 260 to 370 miles. The satellites were successfully deployed on March 15 and will verify their health within ten days. This 18-month mission aims to enhance understanding of how Earth interacts with space and improve space weather predictions. EZIE will use atmospheric drag for orbit adjustments, allowing precise measurements of electrojet formation. The mission also includes distributing magnetometer kits for educational purposes, combining ground and satellite data for a comprehensive view of electrical currents.
