Carnarvon’s first mission was a real Australian Outback story of the bush telegraph. It was Wednesday 8 April 1964 and the first unmanned Gemini trial, GT-I, was sitting on the launch pad ready to open the Gemini Program with a test of the structural integrity of the spacecraft and the launch vehicle. At Carnarvon the staff were still putting the finishing touches to the new station.
The author remembers that it was 10:22 pm local time – 1 minute 37 seconds to lift off. “We were standing by listening to the count, anxious to prove ourselves with our first mission. Everything was ready – we had all our mission information loaded, the equipment tuned up. Suddenly the line to Mission Control at Cape Canaveral went dead – at the time we didn’t know what had happened, but we were cut off from the outside world by a lightning strike 105 kilometres south of the station.”
Mrs Lillian O’Donoghue, the postmistress and operator of the weather station at Hamlin Pool at the southern end of Shark Bay, was roused up that night by a telephone call from the operator at Northampton, asking if she could contact Carnarvon. Using the bush telegraph – nothing more than a party line of telephones connected to the top strand of the local property fences, or in some places a line strung between the fence posts – Mrs O’Donoghue, who hadonlybeeninthe jobfor four months,was able to speak to the operator 241 kilometres away in the town of Carnarvon.
The mission tracking data from Cape Canaveral was intercepted at Adelaide, and phoned through to the Postmaster General’s Department test room in Perth. The Perth technicians then relayed the information to the technician at Mullewa, who established a phone patch through Northampton to Mrs O’Donoghue, and she and her husband then passed blocks of figures in half hour segments on to the Carnarvon operator from 10:30 pm until 3:45 am. From the Carnarvon telephone exchange it was a simple matter to get the information to the tracking station and the FPQ6 radar, a key element in the early phases of NASA launches from Cape Canaveral. It was 3 am before the PMG linesmen battled through driving rain and several washouts to get the normal landline operational again. After this episode a special tropospheric radio link was built between the station and Perth, and there were no more major communication breakdowns.
As Carnarvon had all the mission data already loaded before the lightning struck, the most important information was the time the spacecraft was launched and any changes. As Carnarvon wasn’t officially completed and not a critical station for this particular mission, the launch went ahead, leaving Pad 19 on 8 April 1964. Sent into orbit faster than expected, the spacecraft ended up 34 kilometres higher than planned. One of the only two powerful FPQ6 radar’s tracking at the time, Carnarvon followed the spacecraft over Australia until the mission was terminated after 64 orbits on 12 April, and came down in the South Atlantic.
George Low joined NASA as Chief of the Office of Space Flight programs. He suggested the next goal after orbit should be a circumlunar flight which would lead to a landing on the moon. A landing on the moon would be NASA’s long term goal.
NASA realized a circumlunar flight would require a spacecraft that could provide life support for more than one astronaut and be capable of reaching a velocity of 25,000 miles per hour in order to escape from Earth’s gravitational field. It would also have to shield the crew from radiation while traveling to the moon and be able to withstand reentry to Earth’s atmosphere at this speed, which was much greater than the 17,500-mile-per-hour orbital reentry. The big spacecraft would be far heavier than the booster capacity of any planned military missile.
