Dennis Wingo: We often talk about the ground stations for Lunar Orbiter. Here is a chart that shows the coverage of the DSIF (Deep Space Instrumentation Facility) the precursor of the Deep Space Network (DSN). for Woomera, Goldstone, and Johannesburg. In 1965 when this graphic was created, the Madrid station was still under construction. You can see the overlap between Woomera and Goldstone quite clearly. Out to lunar distance the overlap is even greater. Larger image.
