5.0 out of 5 stars A very important book, February 3, 2015

Book review for "Asteroid Mining 101"
Date of this review: 03 FEB 2015

The book itself is high quality and has clear, easy to read text and many color illustrations.

The book is a follow-up of Mr. Lewis's earlier book "Mining the Sky" but the information here is much more complete, updated to what is known in 2014, and is much more technical. It would be extremely useful, for example, for politicians, investors, or business executives needing to quickly understand the basis for the recent interest and practicality of asteroid mining.

I have bachelor's degrees in applied physics and computer science and it took me about a week to read this book, spending a few hours a night on it. I enjoyed it very much and I will probably read it 2 or 3 more times just to be sure that I understand everything because there is a lot in it to take in. To get the most out of this book I recommend you read Mr. Lewis's other book, "Mining the Sky", first, especially... Read more

5.0 out of 5 stars Asteroid Mining 101. and 201, and 301. It's all here!, August 3, 2015

This review is from: Asteroid Mining 101: Wealth for the New Space Economy (Hardcover)
There aren't very many science books about space exploitation that rate five stars, but here at last we have one. Lewis states in his preface that he's not going to try to hype the subject matter, and he doesn't disappoint! His presentation is purely matter-of-fact.

In a little more than two hundred pages (including appendix) he packs just about all there is to know about all the asteroids: the near-earthers, the main belt, the Centaurs, the Trojans from Earth to Saturn, the hard-to-access high-inclination space rocks, and even the outermost retrograde-orbiting satellites of Jupiter and Saturn. He explains their orbital statistics and kinematics, the optimal trajectories for reaching them, their minerology (based upon telescopic spectroscopy and meteorite data), and their profit potential. Necessary technologies and techniques for capturing them and extraction of their ores are described thoroughly, though specific engineering solutions are only suggested. This covers just... Read more

5.0 out of 5 stars Not just about Mining but also Planetary Defense, June 29, 2015
Verified Purchase(What's this?)
This review is from: Asteroid Mining 101: Wealth for the New Space Economy (Hardcover)
I found this book by John Lewis quite interesting and valuable. Although I have always been interested in space development and colonization, I had recently been discounting the importance of planetary defense as the basis for arguing for increased investment in the space program. I thought most hazardous asteroids had been identified and the risk of a really significant impact anytime soon was pretty low. After reading this book, I realized how unpredictable the solar system can be due to complex gravitational interactions among bodies of various shapes and sizes. Now I'm back to using defense from asteroid and comet strikes as an important justification for investment in NASA. Of course, in the long run money gained from mining will be the big motivator, but a bunch of billionaires have already figured that out so I don't have to argue that point with them. There were some technical issues with this book, one whole page is duplicated, but overall I recommend it highly for the... Read more
