Keeper of the Objects 144
cEnTiBeE writes that this is "not about the Matrix," but rather about Near Earth Object tracking. "It's accomplished by a staff of 2.5 people watching to see when any 'vermin of the sky' plan to pay earth a visit. This piece titled Keeper of the Objects is in the August '03 issue of Scientific American."

There are only a few things that hollywood does get right with respect to science, and this in particular.
1. We are presumably now at the first time in history that something could be done to avoid such a cataclysimic event.
2. Early detection is the key, It is far easier to deflect something millions of miles away, than it is when it is 4 minutes from impact.
I would place the protection of our planet from those things that would kill us all, as far more important than ensuring people didnt cheat on their taxes, and arn't sneaking booze in on the airplane, but, I dont choose where the tax dollars go... yet.

All current /.ers will be dead by the time a big asteroid probably hits, but we should still have a plan.

Actual Frequency of Impact (Score:5, Informative)
10m - every 1-5 years
100m - every 1000 years

The Tunguska blast of 1908 was a roughly 100m asteroid, hitting land.
If it had been an ocean impact, it would have produced significant tsunamis.
On the remote chance it had landed right on top of a large city, then the city would be completely gone.
A 1km asteroid would wipe out a moderate US state, or create tsunamis that travel to most of the globe. Either way it would affect the climate due to dust clouds.
The observational population census for Earth crossing objects is only complete for objects in the 8-kilometre diameter range (such as 1627 Ivor) or larger. The detection completeness for 1 kilometre range is estimated to be in the region of 12%.

Maybe it's worthwhile upping the budget so we can track all of them down to 1km ?
Re:Actual Frequency of Impact (Score:5, Informative)
Kinda a' nitpick, but the Tunguska object didn't hit land, it was an air-burst. That's the reason there isn't a huge crater there now. It flattened all the trees for hundreds of square miles, but in the very center of the blast, no crater. Stumped a bunch of scientists for a good long while. Air-burst detonations have a larger area of immediate effect (i.e. flattened by the blast wave), but their global effect is less than ones that actually impact. Either way you get lots of knocked over trees and some pretty sunsets.

The first step should be determining whether those "frequency of impact by size" numbers are accurate and what the distribution of of impacts are - in terms of frequency and mass. One doesn't need to monitor all (dangerous) sizes for this estimate.

At 15 megatonnes it wouldn't have raised much more than a ripple. The US exploded larger bombs at sea level.
The rest of your point is well taken though, although you left out one bit. Would Dubya, Putin or our little poodle in the UK wait to confirm the source of an explosion that took out one of their cities before launching a nuclear attack against their evil guy of the week?
