The trio of spacecraft was deployed into orbit via a SpaceX Falcon 9 rocket, which lifted off from Vandenberg Air Force Base on March 15 EDT (March 14 PDT). Following this successful launch, engineers and mission specialists have begun initial checkouts.
Over the course of the next two months, the mission operations team at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, will carry out a comprehensive commissioning phase. This process includes thorough verification of each satellite's scientific instruments and systems to ensure they are fully prepared for operational data collection.
Once commissioning concludes, the EZIE satellites will embark on a scientific campaign to observe and map powerful electrical currents, known as electrojets, within the Earth's upper atmosphere. These currents occur predominantly in the polar regions, coinciding with the dazzling auroral displays seen in the night sky.
By studying electrojets, researchers aim to enhance forecasting of geomagnetic storms and other space weather events. These phenomena can have significant effects on Earth-based technologies, including communication networks and power grids, making EZIE's mission critical for improving our resilience to such disruptions.
