The Case for Mars: The Plan to Settle the Red Planet and Why We Must

"For our generation and many that will follow, Mars is the New World," writes Zubrin. This book went to press serendipitously, just as NASA was making its startling if heavily-qualified announcement that simple life may have once existed on the fourth rock from the sun. Zubrin doesn't spend an enormous amount of time arguing why Mars exploration is desirable -- we all want astronauts to go there, don't we? -- but rather devotes the bulk of this book explaining how it can happen on a sensible, bare-bones budget of $20-30 billion and a "travel light and live off the land" philosophy.
