Tyson is an eloquent spokesman for his "Cosmic Perspective." Though Space Chronicles is a non-book (i.e., a compilation of "15 years worth of commentaries"), it manages to include much useful information, packaged in bite-sized snippets. Those looking for a treatise on astrophysics, or a detailed rendition of the latest cosmologies will have to look elsewhere. This is popular science, the audience of which, appears to be the intelligent voting citizen. Tyson makes the case for NASA funding ad nauseum--figuring, I guess since the politicians don't have the brains to adequately fund science, that it is up to the semi-literate public to properly motivate them. He may be correct, and they could do worse in looking for a political primer on astronomical matters than this book.
