This took me a long while to read, and I'm a little ashamed of that because it's a great book. And yet, taking so long (seven months!) to read it was a wise choice. It's heavy on the technical space stuff—which, frankly, I loved, being the space buff that I am— so taking a break every once in a while was useful. It's also the kind of book that tells such a fantastical story, that stopping to savor and digest it made it better. When I wasn't reading, I was mulling over the story, dreaming about it, imagining what it would be like to look out a tiny porthole and see the Earth no bigger than the palm of my hand.
The last chapter of the book is specially poignant. Collins wrote this just five years after Apollo 11, so the significance of the space program wasn't yet clear, but he does address some of the issues we're still hearing about today (issues that people like Carl Sagan and Neil deGrasse Tyson discussed and are still discussing) about how useful the space program is and why we should continue advancing it. It's sad to see that the space program was doomed from the start in a way, and Collins offers his own explanation for it.
I'd love to send a copy of that last chapter and the preface and introduction to every Congressman, to make them see why the space program is important, but like Collins says, it's a bit futile to show pictures and words, because only traveling 100,000 miles out into space can really wake people up to the importance of space exploration and environmental protection. He says the only way he can describe Earth from Up There is as "fragile", and seeing that fragility and how it translates into the fragility of water quality, air quality, fossil fuels, etc., changed his outlook on what we need to make Earth healthier. One can only hope that the policy makers will realize that without having to stuff the entire government into a space shuttle.
