The company designed, built, and tested the two identical TRACERS spacecraft at its El Segundo facility and is now managing mission operations from its internal Mission Operations Center.
"Millennium has enabled TRACERS through design, production, and now into launch and mission operations," said Tony Gingiss, CEO of Millennium Space Systems. "We are thrilled to be part of this important NASA mission, enabling critical advances in heliophysics science which will help improve our understanding of space weather, ultimately benefitting commercial and national space systems."
The TRACERS satellites launched as the primary rideshare payload aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base. The mission follows final system testing completed in June 2025 at Millennium's Small Satellite Factory.
"TRACERS is the result of strong collaboration between our team, NASA, the University of Iowa, and Southwest Research Institute," said Richard Prasad, TRACERS Spacecraft and MOC Project Manager. "That close partnership was key to delivering two high-quality spacecraft, and we'll continue working together through on-orbit operations to ensure the mission achieves its science objectives."
In space, the twin spacecraft will operate in tandem to study how the Sun's magnetic field interacts with Earth's magnetosphere-key dynamics that influence space weather conditions around the planet.
