I finished reading the book. It's well written, interesting and has some humour in it. I agree with most of the points being made. The first part of the book is mostly about space politics: discussion of the Augustine Committee and of the FY 2011 NASA Budget. The second part of the book (the most interesting part) is about what we should do next. The book is very much pro FY 2011 Budget, pro-capability driven approach and pro-flexible path. It suggests that NASA focus on cislunar space first (as opposed to Mars or a NEO). The Author is not a big fan of SLS and Orion (but the book only briefly discusses SLS and Orion). He would prefer that NASA use commercial solutions and propellant depots.
I disagree with some relatively minor points that are made in the book. The chapter on safety in various modes of transportations makes it seem like all safety improvements were the result of regulations being introduced which seems unlikely given that a lot of safety improvements were more likely the result of technology advances. For example, air bags on cars were brought by technology advances (not regulations). Air bags are now mandatory but regulations is not what caused them to be introduced (competition and innovation were). He also makes it sound like Airline deregulation reduced safety (he gives the example of the Value Jet accident to defend this claim). The first part of the book (i.e., the part on space policy) has a bit of a Democratic slant which I didn't think was necessary given that most of the ideas that he defends also appeal to consistent pro-business Republicans. But these points are very minor. Overall, I really liked the book and give it 5 stars out of 5.
