Space Communications and Navigation Program

The Space Communications and Navigation (SCaN) program places the three prime NASA space communications networks, Space Network (SN), Near Earth Network (NEN) (previously known as the Ground Network or GN), and the Deep Space Network (DSN), under one Management and Systems Engineering umbrella. It was established in 2006. It was previously known as the Space Communications & Data Systems (SCDS) Program.The Office’s responsibilities encompass the management of existing space networks including the Tracking and Data Relay Satellite system, the Deep Space Network, the Ground Network, the NASA Integrated Services Network; implementing any improvements and upgrades to those systems and networks; and developing any future NASA communications and navigation architectures.

It was established in 2006. It was previously known as the Space Communications & Data Systems (SCDS) Program. Before NASA's administrator Michael D. Griffin created SCaN to direct an integrated networks program, different organizations at NASA Headquarters have managed the Agency's space communications capabilities and functions under separate Programs using a variety of administrative approaches. The SCaN Office was established by direction of Griffin in a Memorandum entitled “Establishment of a Space Communications and Navigation Office,” dated July 19, 2006. SCaN operates as a central organization within the Human Exploration and Operations Mission Directorate (HEOMD):
