Tracking and Data Relay Satellite System (TDRSS)

The Tracking and Data Relay Satellite System (TDRSS) is a network of satellites that orbit Earth and serve as communication relays for spacecraft and NASA missions. It ensures continuous contact with orbiting spacecraft, relaying data such as scientific measurements and system status back to ground stations. By providing real-time, reliable communication links, TDRSS allows mission operators to monitor and control spacecraft effectively, regardless of their position around Earth. This system is vital for space exploration, satellite operations, and scientific research, enabling seamless data transfer across vast distances in space.
