As a lifelong "space cadet" (i.e., astronaut wannabe who never will), I looked forward to this book after reading about it in a recent New Yorker story about the renovated planetarium in NYC. I was somewhat disappointed, for several reasons: (1) several pictures were blurred (absolutely inexcusable for this kind of project, and incomprehensible with so many 1000s of pictures to choose from); (2) too much black space (i.e., empty black pages that - even allowing for the aesthetics of leaving a page blank so as to focus on a single picture - left me with the feeling of too much wasted space that could've been used for fabulous pictures; (3) not enough pictures we hadn't seen before, and too many we had; (4) too many moon detail shots that began to look like one another; (5) and digitization of many photos made them look artificial. Having said that, there were 3-4, maybe 5, absolutely stunning shots of the earth that just take your breath away (not the usual "Earthrise" ones - closer in). For those of you who love space photos, NASA has audio-visual units that sell copies to average citizens (of course, we HAVE paid for them already, in a manner of speaking, but they're wonderful for a personal collection). If you're in DC, you can just stop in at NASA HQ and peruse from a selection of 100s/1000s. I suspect other NASA facilities may do the same.
