Mining the Sky (Helix Book) review ↠ 0 Ù While we worry over the depletion of the earth's natural resources the pollution of our planet and the challenges presented by the earth's growing population billions of dollars worth of metals fuels and life sustaining substances await us in nearby space In this visionary book noted planetary scientSpace In this visionary book noted planetary scientist John S Lewis explains how we can mine these precious metals from the asteroids comets and planets in our own solar system for use in space construction projects And this is just one of the poss. The most interesting thing for me was his compelling argument that NEO's asteroids and expired comets in orbits that cross Earth's are much attractive for resource extraction than the moon First the valuable materials metals and water are highly concentrated in the NEO's and second they are less expensive to travel to and from because of their significantly lower gravity than the moon Could it be that Obama's space advisers were influenced by Lewis in their decision to promote a human mission to a NEO over a return to the moonI think he let his enthusiasm for space exploration and colonization get the better of him at times such as when he makes rather extreme estimates of population growth and the resulting inevitability of human missions to NEO's and Mars in the near termStill I found it interesting to the point that I would definitely acuire a revised edition if he were to publish one and I may re read this edtion some day if he doesn't

Ibilities Join John S Lewis as he contemplates milking the moons of Mars for water and hollowing out asteroids for space bound homesteaders all while demonstrating the economic and technical feasibility of plans that were once considered pure fictio. The space mining is of a hook then an overall theme as Lewis spends than half of the book covering the history of space study the development of the tech needed to study space and the fall of NASA He is or less begging people and politicians to get back to space exploration dangling the idea of asteroids stuffed full of platinum as the carrot Some good foundation and background work but I wanted to see speculation on the development of this possible future industry
