You can do it yourself, or at least to those in his organization, at
www.marssociety.org. Not to drop names or anything, but I do have his email
address, though I don't want to give it out here without his permission. In
my experience, though, he responds, however briefly, to most communications,
and, though he exudes an air of impatience, he will listen to what you have
to say when you talk to him.

I agree it is a good work. His first book _The Case For Mars_ is also
great.

Don't know about these things, though I haven't read the whole book. A
little disappointing, though not unexpected. I know a guy who works on
Closed Ecological Life Support Systems, including implementing them in his
own home, who talked with Zubrin about his ideas in my presence, and Zubrin
was the embodiment of skepticism. Strange, from a guy who wants to send
missions to other planets, but it gives you an idea of how feasible he
believes the trip to be.

This one, though, I can comment upon. I think Zubrin is just pandering to
the guys with the money right now, to see if he can squeeze the mission out
of them. He already got them to adopt a minorly revised version of his plan
as their design reference mission, but funding does not seem to be
increasing, and they will not set the correct timetable. They still refuse
to drop the extraneous crap from their list of "necessary steps," the same
bureaucratic nonsense that killed Bush the Elder's plan (they had the balls
to ask for 900 billion dollars. HA!).
Zubrin is not waiting around for the government, however. He (and the Mars
Society) has already started to privately prepare with the Mars Arctic
Research Station (http://arctic.marssociety.org/) sponsored by Flashline,
the Discovery Channel, and others. The next step will be to get private
support for a piggy-back mission on a NASA Mars flight, and then a private
robotic mission to Mars, all with the purpose of preparing for a human
mission. If NASA fails completely, the Society has the goal of a completely
private mission.
Zubrin is, at heart, a die-hard pragmatist. He doesn't feel the need to
help kill NASA by privatization of space flight if NASA will get us to Mars.
