The book is a classic, and was well received by reviewers at the time[...].
In later years other writers went beyond the book in technical details, but never in its breadth of creative vision. And it still has some really cute fictional vignettes of future terraforming activities to head each chapter.
A worthy addition to a space enthusiast's library.
The challenge of restructuring other planets: " ... from releasing the deep-buried, frozen waters of Mars through a 'greenhouse effect' to realigning the moons of Jupiter and creating new moons by transporting asteroids... James Oberg, mission flight controller at the NASA Johnson Space Center, examines the specific problems awaiting us... he also describes improvements that can be carried out on Earth, from increasing fresh-water supplies to offsetting the coming ice age."
We need more thinkers of limitless possiblities, and this author is one of them.
Highly recommended for every reader, teacher, student, worker in astronomy and earth sciences. The reading level is fine for laymen readers of science, too, from high school on up.
Contains some far-out ideas that really aren't, or shouldn't be thought of as such.
How about this idea?: smash Jupiter's Callisto into Mercury! You get a watery world with an iron-silicate core. Presto-change! A new miniature earth.
Here's another: crash some comets into the Moon and outgas some atmosphere. Hey -- you can't do that! the Moon hasn't enough gravity. Everybody knows that!
But wait, says Oberg. That's true on astronomical timescales. But our little moon still has enough gravity to hold onto its new atmosphere for at least one thousand years! Put in, say, a century of work and you get some 700 or 800 years of a new planet. And this does not even take into account efforts to maintain the atmosphere.
There was an episode of the old 1970s sci-fi series Space:1999 in which some alien probes outgassed an atmosphere for the denizens of Moonbase Alpha. I believe it was titled "The Moon's Last Sunset". Perhaps that guys were on to something, or maybe Oberg was a technical consultant? What a neat coincidence!
You will enjoy this unique book.
