I tend to agree with Argos. I don't see a manned Mars mission unless it goes nuclear, i don't think that will happen in my lifetime.

I'd think a manned Mars mission is going to require on the rough order of 100 tons to be landed on Mars.

I don't know what the complexity index is.

I don't see how genocide enters into it, unless the antinuke protestors claim genocide for the launch. If he means suicide, i disagree.

I'd say rockets improved dramatically over the last 80 years, less dramatically over the last 30.

So, that's one agree (no manned landing in my lifetime) one agree in intent but not in actuality (he thinks only a couple tons to Mars, i think a lot more), one don't know, two disagree.
