SUMMARY: Most of the asteroid sky surveys have been carried out in the Northern Hemisphere, but astronomers from the University of Arizona have taken the hunt down under. They're using a refurbished telescope at the Australian National University's Siding Spring Observatory. The new survey is funded by NASA's Near Earth Asteroid Survey, that hopes to locate 90% of the spacerocks larger than 1 kilometre, which have the potential to cause severe devastation if they strike the Earth.

What do you think about this story? Post your comments below.

:( I find it quite worrying, because when they do find an asteroid on a course with us, it would be an unavoidable collision. It takes so long to launch the shuttle (weather permitting) and when we get there, we don't have the means to deflect it safely.

Imagine a nuclear warhead being launched as payload on the Shuttle...how scary is that !! Is anything likely to hit the moon? :o

I worry about asteroid collisions too. A few quick things:
- They wouldn't launch it on the shuttle. It can't get out of low Earth orbit. They'd probably use several Russian Proton rockets.
- The chances of any one asteroid hitting the moon are about one sixteenth the chance of its hitting the Earth. On the moon, smaller asteroids can get all the way to the surface, but no one is there to be affected.

Anyway you can steer the largest rocks to Iraq?

Hopefully they find the way that the asteroids are moving if they find any by that region in space.

Okay vigilance is good, but are there any contigencies to plan if say one was detcted to hit within days, weeks, months, years?

If something as big as the Vredefort (Dome) collision comes..uh..huh, shopping will be off the itinery for a while. There is nowhere to run. I would probably just get up early and watch it happen. :unsure:
