I thank them for taking a chance on me and this project. I also want to thank my editor at Smithsonian Books, Elisabeth Dyssegaard, whose keen editorial eye and intuitive understanding of what I wanted to accomplish unerringly guided the ultimate shape of the book. Thanks also to my agent, Linda Lowenthal of the David Black Literary Agency; Seth Fletcher and Bjorn Carey, who assigned me stories on DARPA topics for Popular Science; Leander Kahney and Noah Schactman, my editors at Wired News; my wife, Wendy Kagan, for her support through another book project; and finally to my good friend Harry LeBlanc for suggesting a variation of the subtitle. INTRODUCTION I FIRST MET THE AUTODOC in a science fiction novel. Back then it was on a starship, and it allowed its user to live practically forever—pretty much a requirement for interstellar travel, even at near-light speeds. Now I was seeing it in the flesh, as it were, squatting in a corner of a Silicon Valley laboratory, looking like a giant mechanized insect with its mouth parts and legs poised over an operating table. The body on the table, like the robot, was artificial—placed there to show what an actual human being would look like in that setting. My tour guide was a forty-seven-year-old mechanical engineer talking a mile a minute, pointing out a cabinet full of surgical supplies and a swing-arm nurse built on the frame of an industrial robot used to working more on cars than on human bodies, and explaining how the system worked. It didn’t take much imagination to bring the scene alive in my mind’s eye. The patient, gushing blood, near death, would be tossed onto the table, none too gently, given the circumstances: massive hemorrhaging that had to be stopped immediately. Strapped down, breathing shallowly, the injured man wouldn’t flinch as the robot maneuvered its grasping parts over his wounds. The mini CT scanner attached to the table would slide down the length of the man’s body, feeding data to the robot’s computer brain. Then the robot would get to work, first jabbing the patient with a needle, then deftly threading a line through his vascular system, guiding it unerringly to the weakly pulsing artery that was pumping the man’s blood out over the table and on to the floor. A pause, while the robot worked invisibly inside the man’s body. And then the flow of blood would shut off as abruptly as a turned faucet as the robot plugged the leak. Whirring and clicking, the robot—apparently satisfied— withdrew its graspers and pulled out the bloody line, replacing it with a simple IV. At an unspoken command, the robot nurse swung over to the supply cabinet, picked up some sutures, and swung back to the robot surgeon. Then it pulled one of the surgeon’s arms off and plugged in a fresh one. The surgeon picked up a suture with its new hand and made quick work of sewing the patient up. Time elapsed from diagnosis to completed surgery: approximately two minutes. And another soldier would live to fight another day. “Want to try it?” the engineer was asking. “Of course,” I said. He seated me at a table before another robosurgeon—the latest prototype— helped me position my hands on a pair of metal grips, and had me lean forward so that I could look through the binoculars on the console in front of me. I was instantly transported across the room to another table, where a slab of simulated flesh awaited my ministrations with needle and suture of my own. I saw the table and its simulated patient in full 3-D color, and my hands registered every bump and jerk as I less than expertly maneuvered my robot’s graspers and tried to sew. I wasn’t just watching a science fiction novel come to life now, I was in one. My visit to the robot surgeon was just one stop on my odyssey through the startling and mind-bending world of an obscure government agency almost no one I speak to casually has heard of but that has affected all of our lives in countless ways. Have you used the Internet? A computer mouse? A satellite- based navigation system? Thank the Defense Advanced Research Projects Agency, or DARPA. My mission in writing this book was to find out what projects the agency was working on today that could prove as influential as those past projects, and meet the people bringing them to life. I FIRST STUMBLED on DARPA while reporting on the world’s first privately funded manned space flights. It was June 22, 2004, in Mojave, California. The TV crews had cranked down their satellite dishes and folded their tents and driven back to L.A. in their trucks and vans, followed closely by the thousands of spectators in their RVs and cars. The windswept little town in the Mojave Desert one hundred miles east of Los Angeles had, in just a day, returned to its usual near-emptiness, punctuated by the sound of the wind whipping flagpoles and the occasional roar of jet engines and the growl of piston engines from airplanes taking off and landing at the airport. Which was now a spaceport. The day before, SpaceShipOne had carried a man, sixty-three-year-old Mike Melvill, outside the atmosphere for the first time. The ship had been conceived by an airplane designer renowned for his shockingly innovative approach to engineering and built by his small company, Scaled Composites, headquartered on the airport’s flight line, for a mere $25 million. That was half the retail price of a Boeing 737–600 airliner. The little spaceship that could, hand-built of carbon-fiber composites, flew three times the speed of sound, faster than any civilian craft yet built. While still far slower than the Mach 25 speed necessary for reaching orbit, SpaceShipOne nevertheless breached the atmosphere and allowed Melvill to float, weightless, for four minutes. News of the achievement now blared in headlines around the world. But I alone, it seemed, among the journalists covering Melvill’s flight, had returned to Mojave the next day to see what a more or less ordinary day looked like at a commercial spaceport. There was no one around. The place might as well have been a ghost town. Everyone was inside, out of the desert sun, working in their hangars and offices during just another day. I began by checking out a rocket company called XCOR Aerospace. As it turned out, that was as far as I got that day. Though one would never guess it from its outward appearance, XCOR Aerospace represented the hopes, dreams, and potential of an age of private space travel as well as any other group of aerospace mavericks, including Scaled Composites. XCOR Aerospace occupied a featureless blue hangar dating from the Second World War. A sign on the door featuring a stylized rocket plane logo was all that distinguished the place. I walked into a battered lounge that was trying without much success to be a lobby. Framed magazine article reprints about the company hung on the walls, including pieces about a home-built airplane the company’s engineers had hot- rodded up with a pair of rocket engines and dubbed the EZ-Rocket. The heart of the operation was an open hangar in which working areas and workbenches had been laid out along the sides. There I met a friendly middle- aged engineer named Aleta Jackson, who I later learned possessed a keen intellect and not a little of the sense of humor required of anyone who has devoted her life to the fulfillment of a dream most people think impossible. She was about as far removed as one could imagine from the stereotypical picture of the fabled steely-eyed missile man of the previous generation, who had started the first space age, the one run by massive government programs, but she was no less committed to the dream of space flight. “Without routine, regular, reliable access to space, I think this planet is hosed,” she told me simply. “We’ve got to have it, and the sooner we get it, the better off everyone’s going to be.” Everyone? “You can do so much more if you have routine access to space,” she explained. “You can bring back resources that we don’t have.” For instance? “One carbonaceous chondrite asteroid three kilometers in diameter will probably produce as a by-product more gold than has been mined to date on the Earth.” XCOR’s chief engineer, Dan DeLong, likewise subscribed to an all- encompassing belief in the transformative power of affordable access to space. “It’s almost a religious thing,” he told me when he joined me and Jackson there in the XCOR shop. “You have to believe. You have to be an optimist. Obviously if we wanted to start a company just to make money, we would have done something much easier.” Lofty though their dreams might be, the rocketeers of XCOR took a very practical and workaday approach to the problems of affordable access to space. They needed investors, so they built their EZ-Rocket technology demonstrator, showing not only that their dreams were built on sound engineering principles, but that rockets could be safely flown as an ordinary part of a viable business. Further demonstrating the safety and reliability of their rockets, the team built a “tea cart” rocket, a small, fifteen-pound thrust, ethane-and-nitrous-oxide-fueled rocket on a rolling cart similar to those used to wheel room-service meals to hotel rooms. In fact, the team actually did fire their device in a hotel ballroom. “And we did it with fire marshal approval,” DeLong said, rightly proud of the achievement. “The fact that we had fire marshal approval is what impressed the investors.” I found this juxtaposition of outlandishly ambitious goals with basic, commonsense business principles and everyday problem-solving inspiring. Unlike Scaled Composites, XCOR did not have a single angel investor with plenty of disposable cash. Its investors expected a return on their investment, it was hoped sooner rather than later. That didn’t bother Jackson, DeLong, or their colleagues. Fresh from the disappointment of being part of a rocket company called Rotary Rocket that had burned through some $30 million in financing without a working spaceship to show for it, the group now subscribed to a “small is beautiful” philosophy. “Having too much money probably causes more companies to fail than having too little money,” DeLong asserted. “You never learn thrift if you start out with too much money.” The XCOR managers’ solution to their cash-flow problem was to find individual customers who also needed some of the technologies XCOR wanted to develop. Their relatively modest first space milestone was a two-seat rocket plane that would take off from a runway on rocket power, without the encumbrance of a jet-propelled mother ship to reach the same kind of altitudes and speeds as the jet-plane-plus-rocket-plane SpaceShipOne system. The rocket plane, Jackson and the others hoped, would find markets among space tourists and among scientists wishing to fly microgravity experiments more cheaply than had ever before been possible. Until they got there, the XCOR engineers hoped to turn enough of a profit in developing some of the technology behind their planned spaceship to fund the development of components for which they either could not or preferred not to find customers. At the time of my visit, the XCOR engineers were well along this path toward commercial spaceflight. They were then finishing development of a piston-driven liquid oxygen pump. Not exactly the headline-grabbing project that SpaceShipOne’s flight was, but in its way, an important development nevertheless, at least as far as people who understood rockets were concerned. People such as the program managers of an obscure research-and-development agency called DARPA. DARPA had invested $750,000 toward getting XCOR’s new pump to work, and now they were watching their investment pay off. At the time I didn’t register much about DARPA other than that it was one of XCOR’s major customers and that it was a government agency. I had started writing a book about small entrepreneurial spaceship companies such as Scaled Composites and XCOR, and it seemed to me that the private sector was where the action in space was, not government programs. The commercial space flight industry had gotten off the ground with the $10 million Ansari X PRIZE for the first privately funded space shot. The prize stipulated that the winner receive no funding of any kind from any government; the prize’s founder, Peter Diamandis, believed that the main reason space flight wasn’t more affordable and commonplace was that government space programs had stifled the innovations that would have made it so. The X PRIZE competitors were inclined to agree with him, and writing about the X PRIZE competition and its aftermath, so was I. And yet, much as I sought to dismiss it, DARPA kept popping up as I researched my book Rocketeers: How a Visionary Band of Business Leaders, Engineers, and Pilots Is Boldly Privatizing Space. There it was funding Space Exploration Technologies Corporation, or SpaceX, founded and led by Elon Musk near the Los Angeles International Airport. Musk had made a fortune by co-founding PayPal and then selling it to eBay in 2002, and now saw space travel as humankind’s best hope for surviving the kind of environmental upheavals that had wiped out the dinosaurs. Musk wasn’t just shooting the moon —he wanted to go all the way to Mars, and hoped to provide the technological infrastructure to allow others to settle there permanently. No mere pipe dream, SpaceX had $100 million in working capital contributed by its founder alone, and it was far along in building and testing a rocket called the Falcon 1. Musk’s team of highly competent engineers, many poached from SpaceX’s big competitors, also believed the plan would work. And so did DARPA, which became SpaceX’s first customer, for a demonstration launch of Falcon 1. And DARPA was funding yet another space start-up, AirLaunch LLC, founded by former Rotary Rocket CEO Gary Hudson, whose mission was to drive down the cost of launching satellites by dropping rockets off the back of C-
