IT’LL BE OUT IN OCTOBER: Just sent off the final pages for my next book, America’s New Destiny in Space. All about where we’re going and why it matters. Short summary: There have been three phases of space activity, and we’re entering the third now. First was the visionary phase of Tsiolkovsky and Goddard. Then was the “command economy” phase of Von Braun and Korolev. Now we’re entering the “sustainable” phase of Musk and Bezos, where spaceflight becomes cheap and reliable enough to pay for itself without taxpayer dollars, making the visionaries’ visions affordable.
