My Attempts

Parkes Radio Telescope

We had a great day out, travelling from Bathurst to Orange, to Parkes, to Cowra, then back to Bathusrt, all in NSW. People have often asked us why we go to Bathusrt, not a tourist destination, but one of the things I like about being on the west side of the Blue Mountains is seeing parts of Oz well off the beaten tourist track.

The Parkes Radio Telescope, completed in 1961, was the brainchild of E.G. (Taffy) Bowen, chief of the CSIRO's Radiophysics Laboratory. During the Second World War, he had worked on radar development in the US and had made some powerful friends in the scientific community. Calling on this old boy network, he persuaded two philanthropic organisations, the Carnegie Corporation and the Rockefeller Foundation to fund half the cost of the telescope. It was this recognition and key financial support from the US that persuaded then Prime Minister Robert Menzies to agree to fund the rest of the project.

Apollo 11
When Buzz Aldrin switched on the TV camera on the Lunar Module, three tracking antennas received the signals simultaneously. They were the 64 metre Goldstone antenna in California, the 26 metre antenna at Honeysuckle Creek near Canberra in Australia, and the 64 metre dish at Parkes.
In the first few minutes of the broadcast, NASA alternated between the signals being received from its two stations at Goldstone and Honeysuckle Creek, searching for the best quality picture.
A little under nine minutes into the broadcast, the TV was switched to the Parkes signal. The quality of the TV pictures from Parkes was so superior that NASA stayed with Parkes as the source of the TV for the remainder of the 2.5 hour broadcast.

The Parkes Radio Telescope can only receive signals, it can't send them.
