Space Surveillance Network

The Space Surveillance Network (SSN) is a system of radar and optical sensors that monitors objects in Earth's orbit, including satellites and space debris. Managed by the U.S. Space Command, the SSN tracks these objects to ensure safe space operations and to prevent collisions. The data collected helps improve space situational awareness, allowing for better planning and response to events like satellites re-entering the atmosphere or debris impacting operational spacecraft. Overall, the SSN plays a crucial role in maintaining the safety and sustainability of space activities.
