The Parkes Radio Telescope
During the Apollo Program, Engineers and
Technicians from Tidbinbilla regularly spent time at Parkes.
As a radio telescope, Parkes is receive-only, lacking a transmitter.
CSIRO agreed, at NASA request, to provide mission support on a number of key occasions during the Apollo Program this was to provide additional signal level margin, and antenna/tracking redundancy. (In addition, the larger antenna meant a narrower beam-width, which was expected to be a help during the Apollo 13 emergency when both the LM and the SIVB IU were transmitting on the same frequency.)
Parkes used NASA payments to enhance the capabilities of the facility and this happy arrangement has continued to the present day.
During Apollo, Parkes was not always called up because the radio telescope cannot point below an elevation of 30° thus reducing potential tracking time.
For Apollo 11, a team from the Goddard Space Flight Center (led by Robert Taylor) were stationed at Parkes (assisted by John Crowe, who had worked at Honeysuckle).
At Honeysuckle Creek, Mike Dinn was responsible for co-ordinating Parkes telemetry through to Honeysuckle, where it could be used as another source (as was the telemetry from Honeysuckles wing at Tidbinbilla).
For later Apollo missions, Manned Space Flight Network personnel from Tidbinbilla, spent considerable periods at Parkes. Keith Aldworth who was a part of the team at Tidbinbilla writes,
(from Keiths biographical note.)
When Parkes was used for Apollo support, the Parkes telemetry was available at Honeysuckle Creek as an alternate source to its own antenna and that at Tidbinbilla.
