Mike Dinn

Mike Dinn was born and educated in England. After graduating in Electrical Engineering (London) in 1955 he worked in British industry mainly on aircraft electronics and electrics.

In 1960 he moved to Australia, and was responsible for aircraft flight testing Instrumentation with the Royal Australian Air Force.

Mike moved to the Canberra Deep Space Tracking Station (Tidbinbilla – part of NASA/JPL’s Deep Space Network) in 1966 as Deputy Station Director in charge of Operations, his first mission being Surveyor.

In 1967 he took a similar position at Honeysuckle Creek, one of NASA’s three main communications facilities for the Apollo program, and was actively involved in manned missions Apollos 7 to 13.

Many who supported Apollo 11 received one of these medallions in a commemorative folder. Here is Mike’s. Photo by Colin Mackellar.

He returned to the DSN station during the building of the new 210 ft dish at Tidbinbilla, and spent a year at JPL Pasadena (1972). This antenna supported Apollo 17 as its first task.

After a period in Australia’s Department of Defence he returned to the Deep Space Station in 1983, becoming Director in 1988. NASA’s main missions during this period were Voyager, Magellan and Galileo, but the facility also supported Shuttle until the TDRSS spacecraft were in place.

Mike retired in 1994 – on Apollo 11’s 25th anniversary, having just succeeded in obtaining an Apollo 11 lunar rock for display, presented by John Young.

Mike considers the highlight of his career as being Apollo 11 operations (and in particular the TV of the first lunar step to the world coming through Honeysuckle), closely followed by being at Houston during Apollo 17 and sending some commands from Ed Fendell’s INCO console on Gene Kranz’s shift, and also Apollo 8 where Honeysuckle Creek first came into its own.

Mike was awarded two NASA Public Service Medals – in 1986 and 1995.

In 2019, Mike’s granddaughter Therese was part of a team which assessed the Parkes Radio Telescope for National Heritage Listing. John Sarkissian took this fun photo of her ‘playing cricket’ on the Parkes dish.

Favourite Mission
(From an online discussion.)

“I had already voted for [Apollo] 8 for the reasons John cites. We worked together on the mission. In retrospect I’m amazed at the confidence we (the whole project) had, but everything possible had been done to prepare, including contingency planning.

Our HSK in-house sim capability came about as a result of a visit I had to Houston, when I sat in on several MOCR simulations with “Network”. I realised that we at the Station didn’t have the same depth of contingency capability as the Flight Control team.

So when I got back to HSK, and with Tom Reid’s support, we decided to build an in-house capability based around some excess consoles from the tracking ship CSQ (which I selected at Fremantle), and various other pieces of equipment to assemble the many Apollo spectrums. I even approached Howard Kyle at Houston at one point to see if we could lay our hands on an excess/spare/prototype PSP (pre-signal processor) which mixed the various signals in the CSM – but with no success.

The only thing we couldn’t simulate was American accents for astronaut and CAPCOM voice, so we had a number of laconic Australian voices pretending to land and step on the lunar surface. Messed it up a bit. The simulations were great for building confidence.

I used to say that the Apollo projects used only about 5 percent of support capability for a nominal mission, but we got to 95 per cent on Thirteen. It was THE mission when the receiver operators earned their money – sorting out the LM signal from the SIVB on the same frequency. We had four receivers at HSK, four at Tidbinbilla and two at Parkes all trying.

And as John said the later missions added a great deal of complexity for us – the Lunar Rover was a complete “spacecraft” itself from a comms point of view.”
