This is a 1/140 scale model of one of the three, 64 m (210 ft) Deep Space Network Antennas. Beginning in 1958, the Jet Propulsion Laboratory of Pasadena, California contracted for the construction of three 26 m (85 ft) antennas, spaced approximately 120 degrees longitude apart, to provide continuous coverage of deep space. Stations were established in California, Australia, and Spain. Beginning in 1962, NASA and JPL began design and construction of three larger antennas. This is a scale model of one of those.
NASA transferred this model to the Museum in 1982.
This object is on display in Kenneth C. Griffin Exploring the Planets Gallery at the National Air and Space Museum in Washington, DC.
