                An overview of the capabilities available from the Deep Space Network to support flight 
                projects and experiment investigations. The capabilities described are focused on deep 
                space missions, near-Earth missions above Geosynchronous Earth Orbit (GEO), 
                and ground-based observational science.  Included are tables summarizing uplink
                commanding, downlink telemetry, radio frequency, and ground communication capabilities
                as well as pricing information for mission support. The document is aimed at mission 
                designers working at the proposal stage; it is updated as appropriate.

    <description>The Canberra Deep Space Communications Complex (CDSCC) is one of the three Deep Space Communications Complexes (DSCCs) that make up the NASA Deep Space Network (DSN). THe DSCCs are spaced by approximately 120 degrees in longitude and within about 40 degrees latitude of Earth's equator. As the Earth rotates, this configuration provides nearly continuous coverage of spacecraft in the ecliptic -- that is, spacecraft flying to or orbiting most solar system objects. The CDSCC, which became operational in 1964, is located in Tidbinbilla, Canberra, Australia, and managed by the Commonwealth Scientific and Industrial Research Organisation (CSIRO). The Canberra complex includes several Deep Space Stations (DSSs, or antennas), a Signal Processing Center (SPC), and administrative and support facilities.  Each DSCC handles several types of data including: frequency and timing, tracking, telemetry, command, monitor, radio science, and very long baseline interferometry. These data types support uplink (to spacecraft) or downlink (from spacecraft) operations or passive reception.  Data received from spacecraft are relayed via the local SPC to the Network Operations Control Center (NOCC) at JPL where where they are distributed to the offices responsible for each spacecraft.  Commands, generated in those offices, are sent via the NOCC, SPC, and DSS to the spacecraft. For more information, see https://www.cdscc.nasa.gov/</description>
