Neil deGrasse Tyson is one of my favourite scientists living today. Not only is he well deserving of his Sexiest Astrophysicist award from People magazine, but he is one of the most passionate, articulate, insightful speakers on the topic of manned space exploration that there is. This book is a collection of his articles and speeches on the topic, so be warned that it can get a little repetitive. The same facts, figures, arguments, correlations, and so on, come up again and again in the text. In fact, that's the only complaint I had here -- when I found time to curl up with this book and spend time with it, I sometimes wanted to put it back down after fifteen minutes, because some chapters seemed like rewrites of the last. However, every chapter is completely satisfying; I would suggest reading this in small doses, like on a short commute, where you can enjoy one or two chapters at a time.
