“One more.” An instant laugh and this time a raised eyebrow and quizzical smile next to his nonplussed face. Flash. “Got it.” She walked off without another word, head down and thumbing her screen. Tighe recalled the Kayapo tribesmen of Brazil. They hated to be photographed. He felt a sudden kinship with them as he feared for his social media soul—then remembered he didn’t have one.

Joyce had risen from middle-class obscurity to become a billionaire at a young age, first in cryptocurrencies and then when one after another of his tech startups (none of which Tighe had heard of or understood) were bought out by tech giants. Now in his late thirties, Joyce had controlling interests in dozens of closely held enterprises in new media, real estate, biotech, aerospace, and renewable energy.

“For example, when a new mortgage is originated, that money does not come out of a bank vault. Instead, the money is created as a result of the loan. The bank supplies it to the borrower as a bank credit, with the borrower promising to repay the principal plus interest at a future date. This new debt is registered with a federal reserve or a central bank to the commercial bank’s account, allowing it to now loan out more money based on a multiple of that new loan—usually at a ratio of ten or more to one. So the more money the bank lends, the more it has available to lend.” Tighe frowned. “Hold ...more

For this reason no nation would win any conflict in low Earth orbit. The wreckage from even modest hostilities would likely impact other satellites, creating clouds of lethal debris, which in turn would hit still more satellites. This could ultimately result in what’s been called the Kessler syndrome—where the area above Earth’s atmosphere becomes blanketed by debris that denies access to outer space to all of humanity for generations.”

It showed they were at 32 meters’ depth and breathing 30 percent nitrox—a mix of nitrogen and oxygen intended to stave off rapture of the deep (the layman’s term for nitrogen narcosis), a false euphoria that could blunt a diver’s awareness and lead to death.

But the problem with breathing a lot of helium was its thermal conductivity—twenty times that of normal air; a diver lost body heat much faster while breathing helium. Tighe watched the screen as he and Oberhaus partially inflated their dry suits with argon gas to insulate them.

Joyce shouted over them. “We shouldn’t just accept that we’re destined to live on whatever planets have been dealt us. If you solve the problems of living on Mars, then you’ve only solved the Mars problem, but if we learn to build habitats in open space, then we have solved the entire future of the human race. We can harvest materials”—he pointed to Goff—“from asteroids, for example.”

“As for the EU, the grand duchy, and the FAA—I’m not going to ask permission. Here on Earth you lawyers say that possession is nine-tenths of the law. Well, Lukas, in space I think possession is going to be more like 99.99999 percent of the law. Space is a goddamned frontier. What’s the use of going to a frontier if it has rules?”

“Asteroid 162173 Ryugu.” A label faded in as he said it. “Discovered in 1999, it is a rare C- and G-type near-Earth asteroid. Roughly 900 meters in diameter and 450 million tons in mass, it contains tens of millions of tons of nickel, iron, cobalt, nitrogen, ammonia, and water—worth an estimated 106 billion US dollars.”

However, Ryugu also contains other vital resources—ammonia, nitrogen, and metals. What makes these resources so valuable is their trajectory above Earth’s gravity well. . . .” The hologram panned away from Ryugu and zoomed in toward Earth once more. “Even with today’s reusable launch systems, it currently costs seventeen hundred dollars per kilogram to lift a payload into low Earth orbit.” A holographic rocket barely climbed off the Earth. “It costs over twice this amount to lift a kilo of payload to a geostationary transfer orbit—or GTO—36,000 kilometers above Earth.”

“Because asteroid dust is an extreme biohazard. It must never get inside your ship. Asteroid regolith is five times finer than talcum powder, with particles as sharp as broken glass. If breathed in, they can enter your bloodstream directly—resulting in death. If taken into the lungs, they can penetrate deep enough to cause silicosis—stone grinder’s disease—resulting in death. Regolith also sticks to and shorts out circuit boards and jams valves and seals—causing equipment failures that can also lead to death.”

Jin shook his head. “No one has built a ship such as this.” “I’m surprised. Spinning a spaceship to create artificial gravity makes sense.” “Only if the radius of rotation is at least 200 meters. Otherwise, the Coriolis effect can sicken the occupants. Imagine gravity changing dramatically whenever you sit or stand up.”

They both rounded out the tour by inspecting the secure storage compartment—which held the time-release lockers. Part of Dr. Bruno’s “psych regimen,” these would be opened at intervals by the ship’s system or by the mission control managers. The lockers contained goodies, surprises, and other items of interest to keep up crew morale.

Consider this: for decades humanity has possessed the capability to expand into our solar system—but we have not.” He let his words sink in, looking from face to face. “It’s not because explorers like you weren’t willing to shoulder the risk. Instead it was a blindness among our leaders that prevented them from seeing the true risk. And yet on Earth, we spend a trillion dollars on war without blinking an eye.

Joyce stared at the screen for several more moments. He looked down as he said, “I have lied to investors in my other companies. I have falsified tax returns and SEC filings. I have embezzled. I have begged, borrowed, and essentially stolen the money required to make this expedition happen. An expedition that officially does not exist because no one was willing to fund something this risky. No one had faith that it could work—and they still don’t. Investors gave me money to do more of the same bullshit that billions of dollars are wasted on every day here on Earth. And I took their money, and ...more
