      It's 909,000:1 that it will miss us, but there's only a 50:50 chance that's right.
    • Sure. But the mainstream doesn't understand uncertanity, or statistics.

      Based on what we currently know, there's 1 chanse in 900K that it'll hit.

      This also means that there's 899.999 in 900.000 chanse that it will NOT hit, and probably 850.000 in 900.000 that it'll miss by so large a margin that even a bit more observation now will tell us for sure that it'll miss.

      No, probabilities are all about uncertainty. After further measurements, there will be less uncertainty, and that affects the probabilities.

      Suppose I have rolled 10 six-sided dice. Without any more information, you'd would say there's a 1 in 6 million chance that they are all fours, and you'd be right. But if you look at one of the dice, you will then have more information: if it's a four, then the odds that all dice are fours becomes 1 in 1 million; on the other hand, if it's not a four, the odds become zero. The latter scenario is five times more likely. Therefore, it is accurate to say that "the chances of all-fours are likely to become even slimmer once more measurements of the dice have been made".

The whole idea was so bonkers, and completely the opposite of normal engineering thinking. "Well, we're going to blast this thing into space using a series of nuclear explosions, so to take the impact it's going to have to be really big and strong. Let's build a spaceship the size of an ocean liner, then". Gotta love that sort of thinking.

      'Horizon' on the BBC covered this issue a while back - see http://www.bbc.co.uk/science/horizon/2003/armagedd on.shtml [bbc.co.uk]

      A quote from the link above:

      Asteroids like sponges

      Three years ago, the residents of Tagish Lake in northern Canada witnessed a bright explosion in the sky, as an asteroid burned up in the atmosphere above them. Jim Brook was lucky enough to find debris from the impact. The first thing he noticed was that it was far lighter than he expected it would be. Like a sponge, the chunks of debris were mostly air.

      Dan Durdan makes his living by firing ball bearings at asteroid samples - meteorites - to study what happens when they are hit. When he tested samples similar to the Tagish Lake meteorite, he was surprised to see that, rather than shattering or being deflected, these less dense asteroids simply absorbed the impact of the blast.

      These results were worrying. This could mean that many asteroids would not be deflected by a nuclear blast. Trying to deflect an asteroid with a blast might have no effect, and would keep it coming on its deadly trajectory.


      The programme also covered an alternative solution (another quote..)

      The power of the Sun

      Jay Meloch has suggested a radical new way of dealing with a dangerous asteroid. He wanted a surer, more controlled way of diverting a large body - with a gentle push instead of a blast. His idea was to find a way of harnessing the biggest power source in the Solar System - the Sun.

      In the same way as you can use a magnifying glass to set fire to a sheet of paper, you could focus the Sun's rays onto a point on the surface on an asteroid. The spot where the Sun's rays met would heat up, blasting particles of the asteroid into space. This would act like a rocket engine, and might be enough nudge the asteroid out of harm's way.

      The scientific community ridiculed his suggestion - until Meloch received a phone call from someone who took his idea very seriously. The US military already uses collectors like Meloch's to gather radio waves. Meloch may well have come up with a suggestion that will one day save the Earth.


      • If the ball bearing did not go all the way through the asteroid sample, but became lodged in it, then all the energy of the ball bearing was transferred into the asteroid. Sounds like firing a ball bearing at the sample at the right angle, were it far enough away, and headed for Earth, would be an effective way of giving it some lateral momentum and changing it's orbit to miss Earth.

        What I want to see, is the effect of a large thermonuclear bomb on an asteroid sample...

        Somehow, I find it difficult to beleive that an extraterestrial object is "mostly air"! Mostly vacuum or mostly some other gas, maybe. Also, what difference does it make if it "absorbs" an impact -- that just means 100% of the impacting objects momemtum has gone into changing the asteroids momemtum. Methinks that would be a GOOD thing if one were trying to deflect an asteroid!
        • Well,

          probabably you should try to calculate how much MASS a asteroid has, and how much momemntum is transfered if one or two nukes HIT it.

          a) when HITting, the nuke wont explode ... hitting an object wich moves with 30km/s means your ignitiator has only very little time to ignition the nuke before the nuke is crushed ...

          b) ignitioning the nuke close by ... like it is done on earth over japan cities ... has absolutely neglectibel effects in vacuum, because there is no atmosphere and the heat alone will onl

      Erm... If you're using a series of explosions to blast nuclear warheads into space, there'd be a risk of potential fallout in case of a failure, no matter what technology you'd use to generate the explosions - nuclear warheads have a tendency to be radioactive themselves...

      Besides: Orion would be "nuclear powered" not in the semi-clean sense of power plants ("Clean unless there's a disastrous failure and if you know a place to store the leftovers for the next couple of thousands of years."), but rather in the sense of an atmospheric nuclear weapons test ("Sure to generate radioactive fallout which will eventually contaminate some area somewhere."), so you don't have to be an "eco freak" to doubt its feasibility.

      If the danger were much greater, it might be considered an option, but for now it looks as if there's not much to worry about anyway.

      You know what the funny thing is? IIRC, that meteor was about 6 miles (a bit less than 10 km) across. That means, this thing is 1/10 the size IN EACH DIRECTION which is more like 1/1000 of the size of the dino meteor. Or more like (1/8)^3, or 1/512 as powerful. OTOH that doesn't take into account relative velocities and such.

    The probability of this one hitting the earth is near to zero, according to the JPL NEO site, but eventually one will turn up with a much higher probability, given that there are many objects that have not yet been discovered and that comets can change their trajectories very rapidly due to outgassing near to the sun.

    I think that most space agencies know this, which is why there is a fair amount of observation and research into discovering, predicting and hindering such objects. For instance, it has been discovered that only the high density non porous asteroids can be reliably moved with nuclear explosions. Porous low density asteroids and comets will need completely different technologies in order to change their trajectories, such as solar powered lasers to melt parts of them and ion engines to manouver the probes.

    Well, looking at the NASA NEO page (http://neo.jpl.nasa.gov/risk/2003qq47.html) shows the actual probability of 2003 QQ47 impacting the Earth in 2014 is 1 in 1.754 million, the highest isolated probability. The BBC's figure of 1 in 909000 is the cumulative probability of the asteroid impacting the Earth in the next century.

    2003 QQ47 only merits a 1 on the Torino scale. That's the same rating given to random events. For anyone to get upset, you'd be looking for at least a 3 (out of 10) which is a 1% chance of a collision and some regional destruction. Compare this to a 10, which is guaranteed collision and global climatic catastrophe. A 10 event on the Torino scale happens every thousand centuries or so.

    Journalists really ought to at least try and understand their subject matter before committing their thoughts to be distributed to the general public. They have a duty of responsibility to ensure that data of limited significance is not represented as some twisted interpretation of a coming apocalypse.

    You mean the crappy Bruce Willis movie. Here I am, thinking the story is about some Nostradamus-related story about the great final battle that destroys the world somewhere in the Middle East. You know, what Armageddon has meant for hundreds of years before Billy Bob Thornton and Ben Affleck were involved.

    Sorry to take this seriously, but enough of the "And I for one welcome our new Asteroid Overlords" jokes. The idea of a scale that measures the likelyhood of impending destruction just seems too wonderful to leave unanalyzed.

    The Torino scale seems a wonderful invention, since obviously the dinosaurs didn't have it, and see what happened to them! But it has an obvious bug, it works only with integer values. Zero means "all clear" and One means "enough danger to panic and start looting". What about "enough danger to reconsider whether life as a tea jockey is really worthwhile?" I mean, it would be really useful to know that the current Torino scale is 0.003 or whatever. People could change jobs and say "Torino went up, I'm reconsidering my life choices!" or whatever. A single decimal Torino jump could be enough to spark divorces, a full digit change enough to halt wars. But we need more accuracy.

    I for one welcome our new Torino overlords!!

    There are approximately 6 billion people on Earth. The odds of this asteroid striking are 1 in 909,000. By my calculations 6,601 people will be struck by this asteroid!

    Why isn't anyone doing anything!!

    Data on this NEO's future return trips from the nasa site (http://neo.jpl.nasa.gov/risk/2003qq47.html):

    Date: 2078-03-22.19
    Distance in earth radius from center of earth: 0.11
    Chance that it won't hit: 0.000

    I REALLY HOPE that there's some new measurements coming out soon...

    All the people commenting that "1 in 909000 is a very small number" or words to that effect, forget that almost every time, someone does get to win the lottery. If we just happen to be in the unfortunate 909000th parallel universe, the fact that it missed in all the others will be small consolation.

    How close can it actually come without causing ill effects? Suppose it missed by 100kM ? 10kM? Can anyone provide enlightenment?

    The Torino scale (a number of the danger level) is nicely explained by NASA [nasa.gov]. To get some idea on how it works, look at this [nasa.gov] Note that a 1 on Torino scale is still in the "Green" (press release) region. This one is also very near the edge of "White" (no press release) region, and likely falls there in a few weeks. I think this scale was mainly created to reduce the number of press releases.

    Personally, I'll start worrying when the propability is more than 1% (Torino Scale 3) and increasing with time.

    • Every time I hear the name "Torino" I'm reminded of the 1973 Ford product that I took driver's ed in. [patopomaps.com] Yes, it was a while ago.

      So I can envision someone creating a mass-equivalent scale using this vehicle because it was his first car. Stranger things have happened.

    Yes, we have this same story twice a year. So how many years will it take us to figure out that even if the chances of a real strike are slim, the certainty of the undesirable outcome of the event should make us begin to experiment with ways to send Bruce Willis' greatgrandson out to nudge it aside? How far could we have gotten with the billions squandered in the Iraq farce?

    Then again, we go out and vote to spend our money bombing a country that was of no threat to us. Maybe we deserve to have a big rock dropped on us.

    I was looking over the JPL's orbital elements and diagrams for this object (here) [nasa.gov], and I noticed the following:

    15 March 2005: The object will be .082 AU from earth.
    24 September 2012: The object will pass within 0.098 AU of earth.

    I also noticed (if I am reading the orbital diagrams correctly) that the points where the object is closest to the earth coincide with the points where the object passes through the plane of the ecliptic. Since these are the Acending / Decending nodes of a solar orbit, wouldn't this point be ideal for a change of orbital plane? I'm thinking these near-Earth encounters may change the object's orbit somewhat, since surely the earth encounters will impart some delta-v on the object.

    Anyone else up on orbital mechanics care to take a better look at the ephermis?

      Also to consider is the fact that as earth affects the object's path, the object affects the earth's path. And don't forget, you must ensure that any changes you make to the object's trajectory is imparted into any fragments you make while changing the trajectory -- if we turn a bullet into a cloud of shot, we are more likely to be damaged.

      But more interestingly -- is 2014 an election year?
