Australia’s contribution to Spaceguard

Spaceguard is the name given to an international effort to search the
skies for asteroids that might collide with the Earth. The name was
coined by Sir Arthur C Clarke in a 1973 novel that described how
mankind set up an asteroid detection and defence network after a
large asteroid struck Italy and devastated southern Europe. Since the
novel was written the risks and grave consequences of asteroid
impacts have been recognised and studied. Scientists around the globe
are now working to ensure that Clarke’s scenario of a sudden, deadly
impact does not occur.

The United States is the main contributor to the search effort, with
several telescopespandicated to Spaceguard. Japan recently
constructed a new telescope facility for Spaceguard work and Europe
is in the process of setting up search telescopes and the vital
support systems to analyse the data from the searches.

Rob McNaught from Siding Spring in New South Wales runs the only
professional asteroid tracking project in the southern hemisphere.
This operation is funded mostly by the United States and is
associated with the Australian National University. It was set up in
recognition of the need for Spaceguard telescopes in the southern
hemisphere. Gordon Garradd, an astronomer from Loomberah in New South
Wales, receives some funds from NASA for critical southern hemisphere
follow-up observations using a home-made telescope.

However, a much greater search effort, including a larger telescope,
is needed to detect asteroids that pass through southern skies. It
would cost several million dollars to set up a suitable facility in
Australia but some of this might be covered by contributions of
equipment from the USA.

Operational costs should be less than $1 million per year. This is a
highly cost effective investment in the prevention of loss of life
and severe economic damage from asteroid impacts.

McNaught and Garradd were previously in a team of Australian
astronomers, led by Dr Duncan Steel, who searched for asteroids
between the late 1980s and 1996. They found about one third of new
threatening asteroids discovered during this period, demonstrating
Australian expertise and the importance of searching southern skies.
Australian government funding for the project was withdrawn in 1996
and the team disbanded.

The United Nations and the OECD have recognised the potential hazard
to our civilisation from asteroid impacts. This month the OECD is
looking at the issue as part of its Global Science Forum and recently
asked developed nations to indicate their plans to contribute to the
Spaceguard effort.

A major global Spaceguard effort could provide decades of warning
prior to an impact. This would be sufficient time to refine the space
technology needed to nudge a threatening asteroid into a harmless
orbit, or to evacuate the predicted impact area. Without Spaceguard
there would be too little warning to prevent a disaster. This is
clearly demonstrated by the recent close approach of a 300m wide
asteroid. It was discovered only a few days before it passed by the
Earth and, had it been on a collision course, there is little that
could have been done to prevent possibly millions of casualties when
an area the size of Tasmania would have been devastated.

We note that a spokesperson for Science Minister Peter McGuaran said
that the Government would look into renewing the funding of a
dedicated Australian Spaceguard programme (The Age, 9th January). We
welcome this reassessment of the issue and look forward to Australia
rejoining the international effort to deal with the asteroid threat.
