The road to the Deep Space Network

The history and current status of the NASA Deep Space Network, a system of 13 antennas of various designs and sizes located around the world to stay in continuous contact with spacecraft out to the edge of the solar system, are reviewed. A major step in the evolution of the Deep Space Network is considered to be the installation of 210-ft-diameter antennas to support sophisticated spacecraft sending data at higher rate back to earth at Goldstone in 1966 and at Tidbinbilla and Robledo de Chevala in 1973. New 340-meter multifrequency beam-waveguide antenna, in which weather sensitive microwave components were to be put in an equipment room, was installed for research and development at Goldstone in 1990.

Designing the United States' initial 'Deep-Space Networks' - Choices for the Pioneer lunar-probe attempts of 1958-59

The paper describes two separate networks for ground-support stations, designed, respectively, by the Space Technology Laboratories (STL) and the Jet Propulsion Laboratory (JPL), to support the series of early Pioneer lunar-probe attempts. Particular attention is given to the characteristics of an ideal ground-support station and to the criteria used for the selection of the antenna, the antenna station site, and the frequency for the STL and JPL networks.
