Here's an excellent argument for space research!
For all who think space exploration is a waste of time and money:

It seemed in that article that most scenarios we would be able to use existing technologies except in the cases where the time to impact was very short. In any case I have read where they think in the next couple of decades we will have mapped out most if not all of the larger near-Earth asteroids that could do significant worldwide or regional damage. If after that there is a future impact event then we can start preparations for it. Dumping a huge amount of money when we probably already have the technology to divert an asteroid and will know the position of most of the larger ones in the near future on the enormously low probability that one will strike the Earth in the very near future doesn't make a lot of sense. Sure it's always possible one might hit the Earth next year, but on a practical level you can't base your response to things like that, especially when the knowledge we have now will probably have a good chance of fixing most of the problems.

At this rate we'll be renaming this forum "the Luddites Bulletin Board"
I think that is a little unfair. I would say it's more a factor of having different priorities than just having an aversion to technology. To me, for a lot of the manned missions the cost to benefit aspect isn't worth it with other more important things that need taken care of. It would be like having an bad illness and suffering from starvation, but instead of buying medicine or food with some money you received you go out and buy a brand new Playstation 3 because you think it's fun.
Plus this is a little off topic but looking back at our recent history it seems in some ways the Luddites might have had a point after all. I can think of a lot of jobs that were, in fact, lost because of automation and increased technology. Why in theory that should lead to the benefit of mankind because we have to do less for more, and it might have did that for a while, in the last half century or so it usually just ends up as an means to divert a disproportionate amount of wealth to a smaller portion of people and lower wages on people that used to make a good living. Maybe they had more forethought than people realized.

And as we've all seen during natural disasters, the government, as well as your fellow citizens, can come up with billions to help feed, clothe and shelter people in just a matter of weeks. So there is plenty of money to go around if we really wanted to help feed the poor.
I have never seen that work effectivly. The most I have ever seen is half-assed solutions that don't amount to nearly enough time, resources, and money and don't really ever solve any problems. In the few instances where it does help, people forget about it after a short time even if the problem persists. If we really could help feed the poor and give them good lives if we wanted, I don't know what that would say about us,...that we really don't want to do that.
Plus I don't buy the argument that it's just a small portion of the amount that is spent and doesn't matter. To that I say so...? If that's the case then you take the money that is there from that and spend it on more important things even if it helps only a little on a scale relatively to something else. I know a lot of people that the "only billions of dollars" form it would help tremendously.
