|NASA Space Network Project Operations Management: Past, Present and Future for the Tracking and Data Relay Satellite Constellation|
Ted Sobchak, Donald Shinners, Harry Shaw
The NASA Space Network (SN) Operations began with the launch of the first Tracking and Data Relay Satellite (TDRS-1) on April 4, 1983 with on-orbit operations conducted from the White Sands Ground Terminal (WSGT) in Las Cruces, New Mexico.
|Automated Spacecraft Communications Service Demonstration Using NASA's SCaN Testbed|

|Commissioning of NASA's 3rd Generation Tracking and Data Relay Satellites (TDRS KLM)|
Jennifer Donaldson, Gregory Heckler, Cheryl Gramling, Benjamin Ashman, Marco Toral, Christopher Carson, Jeremy Lyon
In the summer of 2017, the third and final spacecraft of the 3rd generation of the Tracking and Data Relay Satellites (TDRS) launched aboard an Atlas V rocket from Complex 41 on the Eastern Test Range. Finishing final testing and integration in the first quarter of 2018, the TDRS-M communication and navigation satellite completes a constellation that began service in the early 1980s.
