well well.... freedom of speech, baby. sometimes I wonder if you really have it. I know you brag about it. But do you really want it? the way I see it, it means that all peoples opinions are of equal value, and everyone has the right to express them. But when people disagreeing with your bunch, you try to take this freedom away from me. but guess what, you can't. It's been in the constitution of my country for about as long time as your country has existed. And as I have stated, I do give a rat's ass about this shuttle crasch, but I happen to give more of a rat's ass about other things that also doesn't affect me. And I can not not give a rat's ass about 11/9, because I see and read everyday about US war mongering to "stop global terrorism" and put your flag on top of every flag pole in every middle eastern/south asian country. what your government is doing is raping the rest of the world, under gunpoint. Why should I have to take not being allowed by you to express my opinions on this? Oh, wait... it offends you. Too bad you can't allow only your opinions and suppress others without it not being freedom of speech any longer, huh?
The hypocrisy in this is just incredible.

I wouldn't really be talking about "equal value of opinion" there; just look at your post before that one.

What I like about the US is that it is the great terrorist power of the world (in disguise, of course), and nobody can do a thing about it.

so, tell me exactly why spending billions of dollars on launching a few people into space is better than having the economy up to speed again to create jobs for people, and thus giving millions of homeless people a chance to get out of the streets and making a decent living, and having somewhere to live? I believe that the money thrown into space would be better spent here on earth. oh, wait... that is communistic. damn.
Because that would do little for the advancement for the society compared to the scientific benefits of the space programs. There are more than enough people in the world anyway, and they are quick enough to regenerate to keep the population at least at its current level despite any poverty. Besides, this is a US program, and while poverty is an issue in this country, it is not so much of a problem as to suck away all of the space money.
Oh, and I am a quasi-communist myself, so you don't need to worry about me calling you that.

Back on the topic (sort of), how would that nuke propellant system that was brought up here a few weeks ago compare here? Since it does not carry the explosive liquid hydrogen fuel and the nuke plates need to be properly armed before detonation, it would seem that there is less of a chance of an accidental explosion.
