NASA’s GNEISS mission will launch from Alaska in early 2026 to probe the electric currents that drive auroras. Two rockets will fly through glowing auroral arcs, releasing sub-payloads whose radio signals act like a CT scan. By mapping electron density and direction, scientists aim to improve space weather forecasting and better protect satellites and communication …NASA’s GNEISS mission will launch from Alaska in early 2026 to probe the electric currents that drive auroras.
