Hey SM...
Hi Spacers
SM have you read Bob Zubrin's "Entering Space"? What did you think?
I have been looking at some of his arguments and as I mentioned below I disagree with his assessment of SSPS. I suspect he has muddled a few other calculations too, but on the whole he argues well that we need a Government push towards Space colonisation and I think Mars is the best goal in near-space.
Your thoughts?
Adam

Did you catch my reply to your biomass post?
