The book has just arrived. It is a signed copy, which surprised me.
Anyway, I have read through the first five chapters. It is an easy read. Not too technical, but you still have to be something of a space geek to appreciate it.
I do appreciate it. If there's one thing that I've learned over the past three years since I got interested in space, is that mass is your biggest hurdle. The less fuel that you use, the better, since it means less mass. Less mass means better economics. To make it more popular and accessible to the public, it needs to be cheaper. This should be quite helpful towards that objective of leaping that hurdle. We'll need to know about these techniques if the promise of space travel is to reach its potential.
I am excited to finish reading this book. But, as usual, I don't have time to read it all in one sitting. Other things to do.
