Ken Murphy critiques recent pieces by both Bob Zubrin and Gregg Easterbrook. I may take a shot at the Easterbrook thing myself a little later, if I get time.

I still await the opportunity for an on-line debate on space with Gregg, but he doesn’t seem interested in doing that with anyone who knows what they’re talking about.

Clark Lindsey has further thoughts:

Seems like he could call a scientist like Paul Spudis or Larry Taylor and listen to their reasons for advocating a return to the Moon. But I guess contrary facts would mess up the flow of his essay.
