In this dialogue, visionary astronautical engineer Robert Zubrin lays out the plans for how humans can become a space faring, multi-planetary civilization, starting with the competing entrepreneurs like Elon Musk and Jeff Bezos who are creating a revolution in spaceflight that promises to transform the near future. 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. Zubrin and Shermer also discuss: • what the Apollo program meant to Zubrin and to the current generation of space engineers and explorers • the balance between government and private enterprise for the future of space exploration • comparing future space explorers with past earth explorers • why type of government should be established on Mars • what if a tyrant takes over the Martian colony and controls the air? • what type of new species we will become if we establish permanent civilizations on other planets and moons? • is human progress inevitable? • the role of freedom in human progress.
