The support which was provided by the Deep Space Network to the Viking Extended Mission from December 1976 to May 1978 is described. Tracking and data acquisition support required the continuous operation of a world-wide network of tracking stations with 64-meter and 26-meter diameter antennas, together with a global communications system for the transfer of commands, telemetry, and radio metric data between the stations and the Network Operations Control Center in Pasadena, California. Performance of the deep-space communications links between Earth and Mars, and innovative new management techniques for operations and data handling are included.
