"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."--Publisher's website.

Using an integrated philosophical and historical approach, this book explores the fundamental shift in understandings of space in the scientific revolution.

A revolution in spaceflight is likely soon with the prospect of everyday access to orbit within fifteen years. Costly launch vehicles based on ballistic missiles will be replaced by ‘spaceplanes’, using technology that exists today. In five years' time, a prototype could be built, and with a further ten years of detailed development, the design could approach airliner maturity, reducing the cost of sending people into space some one thousand times to around US$20,000.Spaceplane development has, in effect, been suppressed by entrenched thinking and short-term vested interests. But the present monopoly of large government space agencies is becoming unsupportable, and the market that understands the very real opportunities for space travel will be reaching critical mass in the near future.This book examines these issues and shows why space tourism will one day become the single largest business in space, and how astronomy and environmental science will be transformed by low-cost access making possible instruments vastly larger than those of today.

Provides a description of the major ideas about void space within and beyond the world that were formulated between the fourteenth and early eighteenth centuries.
