OPINION: The eyes of the world’s space expertise will be on Australia this month, as Adelaide hosts the world’s largest space conference.
The meeting occurs in the 50th anniversary year of the launch of Australia’s first satellite, WRESAT. This project occurred as the culmination of a decade in which Australia was seen as a significant player in the space arena.
But now, Australia is perceived to be underperforming in the space sector. It remains one of only two OECD countries not to have a space agency (the other nation is Iceland).
So what happened in the past half century to slow us down? My doctoral thesis is attempting to find the answer.
The International Geophysical Year
Australian involvement in space activities commenced with participation in the International Geophysical Year (IGY), a global scientific research program focused on understanding the Earth’s relationship to its surrounding space environment. Longer than a calendar year, the IGY ran from July 1, 1957, to December 31, 1958, and was a significant catalyst for space-related activities in many nations.
In mid-1955, the USA and the USSR had both announced their intention to launch a satellite during the IGY.
In that same year, Britain and Australia’s Weapons Research Establishment (WRE) announced their IGY plans to launch sounding rockets for upper atmosphere research from the WRE-managed Woomera Rocket Range. Located in outback South Australia, the range had been established in 1947 under the Anglo-Australian Joint Project as a guided weapons development and test facility.
The decision to launch “sounding” (sub-orbital measurement-taking) rockets there for the IGY, coupled with US plans to launch the world’s first satellite, would lead to Woomera becoming the hub of early space activities in Australia.
The "space age" truly dawned in October 1957, with the surprise launch of the USSR's Sputnik 1 satellite beating the US into orbit. A space race between the two Cold War superpowers commenced, with Australia poised to participate in the openly scientific and covertly military adventure of space exploration.
Rockets, satellites, citizen scientists
Britain’s Skylark sounding rocket program (1957-1979) would become the longest-operating space project at Woomera, launching British, Australian, European and American scientific instrument packages. Australian and British researchers made substantial contributions to X-ray, infra-red and ultra-violet astronomy using Skylark rockets.
Although the WRE’s first sounding rocket program was unsuccessful, the development of the Long Tom rocket in 1958 paved the way for a succession of Australian sounding rockets operating until 1975. This program, conducted in conjunction with the University of Adelaide, carried out upper atmosphere research that made important contributions to understanding the factors governing Australia’s meteorology.
Australia was also ideally located, geographically and politically, to host facilities for the two networks planned to track America’s proposed satellite, Vanguard. These were: Minitrack (a radio-interferometry system), and the Smithsonian Astrophysical Observatory’s Baker-Nunnoptical tracking telescope cameras.
Project Moonwatch volunteers, mostly amateur astronomers, supported the Smithsonian Astrophysical Observatory’s work by spotting faint satellites and establishing their orbital co-ordinates so that the observatory’s high-precision camera could be then be focused on the satellite. Australia boasted five initial Moonwatch groups (Sydney, Melbourne, Adelaide, Woomera and Perth) – the first citizen scientists of the Space Age.
NASA takes over
When NASA was formed in July 1958, it assumed control of these original tracking stations. By 1970, Australia was home to the largest number of NASA stations outside the USA, hosting facilities for its orbital satellite, "manned" space flight and deep space tracking networks.
These facilities, managed and staffed by Australians, made significant contributions to the early exploration and utilisation of space, particularly the Apollo lunar program. Television coverage of Armstrong’s first steps on the Moon came to the world through the NASA Honeysuckle Creek tracking station in the ACT (with the rest of the television during the Apollo 11 mission relayed via the CSIRO’s Parkes Radio Telescope).
Although advances in technology eventually rendered most of the Australian tracking stations obsolete, the NASA Deep Space Communications Complex at Tidbinbilla, near Canberra, continues to play a major role in the exploration of the Solar System. It was the station responsible for monitoring the final hours of the Cassini mission to Saturn, which concluded with the spacecraft’s death-dive into the planet’s atmosphere on September 15.
Defence focus, and WRESAT
Defence-related space research commenced at Woomera in 1958 with the Black Knight and Jabiru programs.
Investigating nuclear missile warhead design, materials and re-entry phenomena, defence research programs continued until just before the termination of the Joint Project in 1980.
Particularly important to the Australian space story was the US-led SPARTA Project (1966-67): the generous donation of a spare launch vehicle from this program enabled the launch of WRESAT (Weapons Research Establishment Satellite), Australia’s first satellite.
With a launch vehicle available, WRESAT was designed, constructed and launched in only eleven months: a significant achievement in itself. A collaboration between the WRE and the University of Adelaide, WRESAT’s scientific instrument package was derived from the Australian upper atmosphere sounding rocket programs and helped to corroborate their findings.
Launched on November 27, 1967, WRESAT gave Australia entry into the exclusive “space club” of countries that had orbited a national satellite.
At the end of its first decade of space activity, Australia had launched its own satellite, while a Melbourne University student-built amateur radio satellite awaited launch in the USA.
The WRE had an active scientific sounding rocket program, participated in defence space projects and was supporting the European Launcher Development Organisation’s (ELDO) satellite launcher test program at Woomera.
The country was a crucial participant in NASA space programs, through the tracking stations in the country, and an Australian (Dr David Forbes Martyn) chaired the UN Committee on the Peaceful Use of Outer Space’s Scientific and Technical Subcommittee.
Space program proposed, and rejected
To build on these achievements, in 1968 the WRE proposed a modest national civil and defence space program, which could have harnessed WRE and civil space capabilities towards the development of an Australian space industry. The proposal was rejected by the Gorton government on the basis of cost.
This marked the beginning of a cyclical process that has, at least in the civil sector, hindered Australia’s ability to maintain its original level of space capability, or redevelop it over recent decades.
Political parties of both persuasions have shown shortlived, underfunded, bursts of support for developing an Australian space industry, only to withdraw that support just as these programs were achieving results.
Potentially beneficial membership of the European Space Agency (the European Launcher Development Organisation’s successor), to which Australia has been repeatedly invited, has been constantly rejected, also (ostensibly) on the basis of cost.
