NASA's Tracking and Data Relay Satellite System

NASA's Tracking and Data Relay Satellite System is a network of satellites designed to provide continuous communication relay services for NASA spacecraft in Earth orbit, enabling real-time data transmission between spacecraft and ground control. The system consists of multiple satellites positioned in geosynchronous orbit around the equator, providing coverage for a wide range of NASA missions. This satellite system plays a critical role in supporting NASA's space exploration activities by ensuring reliable communication with spacecraft.
