Keeper of the Objects 144

Posted by michael from the wipeout dept.

    If only they got 1/10th of the budget of the hollywood films.

    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.

      It's a little worry-some that the world doesn't take this threat too seriously. One would think that we'd pool our resources and make more of a collaborative effort across the globe to prevent such a catastrophe. I'm not saying each country spend ludicrous amounts of money, but maybe set up an observation post with a couple of people

      Like another poster said, it'll probably take a populated area getting hit to make us realize the importance of such monitoring.

      If we detected an asteroid on a collision course France would say that's evidence the inspection process is working and we should continue inspections rather than use force.

    There's a relationship between asteroid size and predicted frequency of impact.

    10m - every 1-5 years

    100m - every 1000 years

    1km - every 100,000 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%.

    (further reading is here [spaceguardindia.com])

    Maybe it's worthwhile upping the budget so we can track all of them down to 1km ?

      The Tunguska blast of 1908 was a roughly 100m asteroid, hitting land.

      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.
      • Recent analysis shows that the smaller ( 250m) silicate based (rocky) asteriods will airburst. It would have to be pretty damn big to survive hitting the surface. Iron asteriods will almost always survive to impact. Fortunately, the iron asteriods are the minority.
    • Monitoring sounds like a good idea but if you can't do anything about it, it is kind of useless.

      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.

      The second thing should be deciding whether the estimated risk merit development of technology to deflect asteroids.

      Only after the technology is developed it makes

    • Careful now. How about talking in terms of the probability of an impact tomorrow (hint: it's the same as the probability of an impact on any given day, including on a day when another rock drops), not in terms of the duration between impacts. Politicians are easily confused, especially around budget time, and might very well think that we're safe for the next X years.

      It was at most 50 metres across and made largely of ice, it would never have made it to the surface.

      If it had been an ocean impact, it would have produced significant tsunamis.

      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?
