"In his new book, The Case For Space: How the Revolution in Spaceflight Opens Up a Future of Limitless Possibility, famed astronautical engineer Bob Zubrin talks about the how and the why of our new exploratory era. It's a must-read for anyone interested in the subject, and will probably be read by historians of our era centuries hence. I find Zubrin's arguments compelling, and I think you just might, too. I highly recommend his book, not only for its excellent analysis, but also as a source of perspective on today's news. " -- Glenn Harlan Reynolds, Opinion columnist, USA Today A new space race has begun. But the rivals in this case are not superpowers but competing entrepreneurs. These daring pioneers are creating a revolution in spaceflight that promises to transform the near future. Astronautical engineer Robert Zubrin spells out the potential of these new developments in an engrossing narrative that is visionary yet grounded by a deep understanding of the practical challenges. Fueled by the combined expertise of the old aerospace industry and the talents of Silicon Valley entrepreneurs, spaceflight is becoming cheaper. The new generation of space explorers has already achieved a major breakthrough by creating reusable rockets. Zubrin foresees more rapid innovation, including global travel from any point on Earth to another in an hour or less; orbital hotels; moon bases with incredible space observatories; human settlements on Mars, the asteroids, and the moons of the outer planets; and then, breaking all limits, pushing onward to the stars. Zubrin shows how projects that sound like science fiction can actually become reality. But beyond the how, he makes an even more compelling case for why we need to do this--to increase our knowledge of the universe, to make unforeseen discoveries on new frontiers, to harness the natural resources of other planets, to safeguard Earth from stray asteroids, to ensure the future of humanity by expanding beyond its home base, and to protect us from being catastrophically set against each other by the false belief that there isn't enough for all.

Our Worlds provides a rare "insider" look into the universe and planetary science during the current golden age of space exploration. Readers are guided on an exciting voyage of discovery by eight distinguished researchers who explore the universe with cutting edge techniques. From Chief Scientist on NASA's New Millennium Program Ellen Stofan to planetary theorist Bill McKinnon, each writes from a personal point of view, sharing to the fullest the science and emotion found in the most enticing discoveries and the wonders of the solar system. This volume gives readers an up-close view of Mars, Venus, and the Moon; a trip with Halley's Comet; a visit to the moons of Io, Titan, and Triton; and the ability to experience asteroids in their natural element. Coverage details the most current knowledge of the solar system learned from space missions, including Magellan and Galileo. This volume fully captures the breadth of planetary science, from inner to outer worlds, from telescopic to robotic exploration, and provides an unique glimpse into the drives and interests of the men and women behind the science. It is the most encompassing book on the subject to date and will interest anyone who looks at the night sky and wonders what it would feel like to be able to get a closer look.
