On January 27, the three spacecraft that make up NASA’s Electrojet Zeeman Imaging Explorer (EZIE) mission reached the launch site at Vandenberg Space Force Base in California, where they will undergo final preparations and integration onto the launch vehicle. EZIE is scheduled to launch no earlier than March 2025 as part of the Transporter-13 rideshare mission with SpaceX via launch integrator Maverick Space Systems.
The EZIE mission — led for NASA by the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland — will take groundbreaking measurements of the auroral electrojets, which are powerful electric currents associated with the auroras that flow in the upper atmosphere near Earth’s polar regions.
