Vandenberg Launches NASA's TRACERS Mission
Vandenberg SFB Guardians and Airmen supported the NASA Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites (TRACERS) mission launch aboard a SpaceX Falcon 9 rocket from Space Launch Complex 4E (SLC-4E) at Vandenberg Space Force Base, July 23, 2025. The TRACERS mission placed two satellites in sun-synchronous orbit, ensuring consistent observation of Earth’s dayside polar cusps. By comparing data from both spacecraft, scientists will track how magnetic reconnection events evolve over time and build a large dataset of thousands of events to improve understanding of space weather’s impact on Earth.
