## Why It Matters
SBSS-1 plays a critical role in monitoring the increasingly congested space environment, enabling the U.S. military to identify potential threats such as hostile satellites or debris. Unlike ground-based sensors limited by weather and geography, SBSS-1 provides persistent, space-based surveillance, enhancing the accuracy and timeliness of orbital tracking. This capability is essential for protecting operational satellites, planning safe launch trajectories, and ensuring the long-term sustainability of space operations. By addressing the challenges of space situational awareness, SBSS-1 contributes to national security and the responsible use of outer space.
