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".

Nope. With a fair coin it is proper to talk of the probability being 50:50. The difference between a fair coin and celestial mechanics is that with a fair coin it is not possible to define an experiment which will determine the result in advance. In celestial mechanics it is not only possible, but very straight forward. The experiments will in fact be done, and that is the reason the "probability" will change over time before the date of potential collision.
The thing is that real probabilistic analysis is used in computing the pseudo-probability which is the odds 909,000:1. Taking the information at hand, they compute a volume of space through which both the rock and the Earth might pass through during the given time and then compute the probability of them both being at the same place at the same time within that volume. As the quality of the information improves the volume decreases and the pseudo-probability more accurately approximates the actual probability. The odds either get extremely large or closer and closer to 1:1. (I'm being sloppy here, and not talking about gradients. A real analysis would have different probabilities of being within different parts of an infinite volume.)
On the other hand, this is in fact boringly technical. Pseudo-probabilities are very useful, and it is only natural to call them probabilities in normal conversation. You only have to worry about the difference when actually computing the pseudo-probabilities.

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.

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.
