For the first time in recorded history, on the 6th of October 2008, humanity became aware of an imminent asteroid impact and predicted where and when it would hit. On the heels of the hundredth anniversary of the Tunguska Event, this particular impact fortunately occurred over an unpopulated area in far nothern Sudan.
Earth’s history is punctuated by recurrent catastrophic impacts from space. In this particular case, however, asteroid 2008 TC3 was comparatively small (between two and five meters in size) and relatively harmless. Any future impact could be catastrophic if the asteroid is larger and the impact zone is a population center.
There is a strong possibility that over the next fifty years the international community will have to make a decision on whether to act to prevent such an impact. In the next twenty-five years, there is between a one in twelve and a one in twenty chance of a Tunguska level impact with destructive capabilities of approximately two-hundred Hiroshima atomic bombs. Fortunately with current technology these sorts of existential threats to civilization can be prevented--provided there is sufficient warning.
Following an influential 2008 report put together over two years by the Association of Space Explorers and its distinguished international panel of diplomats, legal specialists, disaster management leaders, and international scientists, this issue is now squarely on the United Nations agenda. Australia needs to be an informed participant in this process and a contributor to the geopolitical decisions made through ongoing global surveys and discoveries. [1]
Aside from the work mostly funded by the United States here at the Siding Spring Observatory, there is little being done on this issue in the Southern Hemisphere. Australia has an opportunity to go above and beyond by collaborating with the U.S.-led international effort to track down all Near Earth Objects (NEOs) to 140-meter sizes.
To do this, we could expand and upgrade the Anglo-Australian Observatory and resurrect its role as the leader of the southern sky survey. [2] Australia could also consider coordinating a joint project with New Zealand, South Africa, Namibia, and Chile, to construct a number of new (two- and three-meter) telescopes. Such an array of telescopes across the southern hemisphere would bridge the gap and alleviate our current blindspot in the ongoing survey of the heavens.
Mr. Prime Minister, we ask that you reverse the previous government’s misguided decision and restore sight to Spaceguard in the Southern Hemisphere. [3] We ask that you bestow better science policy to future generations.

[1] “Australia is arguably the most advanced country in the hemisphere,” says Dr. Philip K Chapman, “failure to contribute to the international effort is grotesquely irresponsible.”
[2] Before the Spaceguard Australia program was shut down in 1996, it was responsible for one third of all NEO discoveries due to its unique global location. It is understood that astronomers from other important fields were unwilling to support Spaceguard at that time because of the unstated threat that the funds would come from their budgets. Although science is a very important component of Spaceguard it clearly deserves support from other budgets such as defence and emergency services.
[3] The term Spaceguard was coined by the late Arthur C Clarke to describe a project to detect and deflect all Earth-threatening asteroids, after a fictitious impact destroyed central Italy on September 11 2077. This term has been adopted by NASA for its congressionally mandated asteroid search program.

The 'Earth-rise' photo was taken by the Japan Aerospace Exploration Agency (JAXA) and Japan Broadcasting Corporation (NHK) using an onboard High Definition Television of the lunar explorer Kaguya (Selene) on April 6, 2008 (JST). The Kaguya is currently flying in a lunar orbit at an altitude of about 100 km. For more, see <http://www.jaxa.jp/press/2008/04/20080411_kaguya_e.html>
