“Rhys never even goes to T2,” Ivy said. “He’s been hanging out with the inflatable structures team.”
“Okay,” Dinah said. “Give me a place to work on T2 and—”
“There’s another thing,” Ivy said, and let out The Sigh. The Sigh was what Ivy did when the powers that be were making her do something ridiculous. It would never show up in the transcript of a meeting, but it changed everything.
“I don’t even want to guess,” Dinah said.
“We have all become characters in a reality TV show,” Ivy said. “You might not be aware of it.”
“Nah, I haven’t been watching much TV.”
“Well, it’s all people have to do anymore, down on the ground. The economy is shutting down, and people are just eating beans and entertaining themselves with screen time.”
“Okay.”
“I’ve been asked to pay more attention to message shaping.”
“Message shaping? What’s that?”
Ivy let out The Sigh.
“Okay, never mind,” Dinah said.
“People want to know what became of their Uppity Little Shitkicker.”
“Really?”
“Yeah,” Ivy said. “People like their ULS. They remember the thing you did with Tekla. Tekla porn is a big thing now too, by the way.”
“I don’t want to hear about it.”
“Anyway, people are asking where is plucky Robot Girl and her mechanical menagerie.”
“That explains some weird emails I have gotten.”
“From random strangers?”
“No, from my own family! I don’t read the ones from random strangers. How about you? What’s your role on the reality TV show, Ivy?”
Ivy stared at her coolly. “I’m the uptight bitch who can’t handle it.”
“Oh.”
“To American viewers, I’m not fully American. To Chinese viewers, I’m a banana.”
“I’m sorry, Ivy.”
“That’s the bad news.”
“Okay, and what is the good news?”
“All the people saying mean things about me on the Internet are gonna be dead in four hundred and thirty-three days,” she said, deadpan.
Okay. It was an example of that dark humor thing.
“After that, none of it matters—except my ability to be of service to Our Heritage.”
“Okay, baby, how can I help you?” Dinah asked. “We could take a selfie, you and me, and I could post it on the Uppity Little Shitkicker blog.”
“You and I are going to go for a ride on the first operational bolo,” Ivy said, “and you are going to be reminded of what one gee feels like.”
Casting of Lots
DURING THE FIRST FEW DAYS AFTER THE MOON HAD BLOWN UP, Doob had spent hours gazing up at Potatohead, Mr. Spinny, Acorn, Peach Pit, Scoop, Big Boy, and Kidney Bean. They were visible in the daytime, just as the moon had formerly been, and even on the rare day when it was cloudy in Pasadena, or he was stuck indoors, he could pull up a window on the screen of his computer and watch them on a live video feed.
After he had figured out that they were going to kill everyone on Earth, he had become a lot less interested in staring at them. He had, in fact, sometimes gone for weeks without looking up at the gradually spreading cloud of debris. Sometimes while walking across a dark parking lot or driving down the highway he would catch sight of the moon-chunks in the sky and deliberately turn his gaze away from them. They filled him with horror and even a kind of shame over the fact that he had once found the whole thing such a fascinating science treat. He did not want to be reminded of it. Instead he tracked the slow disintegration of the moon-pieces through spreadsheets and plots shared with him by his graduate students and his colleagues. He did everything he could to reduce the whole state of affairs to two numbers. One of these was the Bolide Fragmentation Rate, or BFR, which was a measure of how frequently big rocks were being made into small rocks. The other was, quite simply, how many days remained before the White Sky.
On Day 7, minutes after they had met, he and Amelia had watched Kidney Bean fracture into two big chunks, later dubbed KB1 and KB2 (though attempts had been made at the time to give them cutesy names of their own). Three weeks later Scoop had collided with Big Boy and broken into three pieces, SC1, SC2, and SC3. Big Boy itself was now BB1, still fairly recognizable, plus a whole family tree of bits that had shrapneled off its smaller piece, BB2. These were given code numbers such as BB2-1-3, meaning the third-biggest fragment of the largest fragment of the second-biggest piece of Big Boy. Beyond about that level it became difficult, and somewhat pointless, to keep track of them all. Mr. Spinny had caused all sorts of havoc before finally breaking in half; its wayward children MS1 and MS2 had gone winging off in opposite directions and ended up in big eccentric orbits around the rubble cloud’s shared center of mass, occasionally looping in from a great distance and slamming into one of the slower-moving pieces. MS2 had broken Acorn into three pieces just three days before Doob’s memorable Oval Office chat with the president. While he’d been flying back to L.A., a hunk of it the size of an oil tanker had slammed into the Indian Ocean and kicked up a tsunami that had killed forty thousand people on the west coast of India.
After he got home from his trip to D.C., he and Amelia checked into a suite at the Langham, a palatial hotel in Pasadena, so that they could spend a few days together before he went out on a round-the-world journey. All through their romantic dinner on the terrace he made a concerted effort not to look at the remains of the moon. Later they went back to their suite and made love. After twenty minutes’ postcoital cuddling, Amelia rolled over on her side and went to sleep, inviting Doob to spoon with her, but Doob, unable to relax, pulled his tablet onto his lap, put on his reading glasses, and started killing time on the Internet. The French doors to the balcony were open, and at some point the breeze coming in through them obliged Amelia to snuggle deeper under the blankets. Doob got up and walked over to close the doors, and was confronted by the sight of the moon-cloud, directly in front of him, hanging over the lights of L.A., and now something like four times the diameter of the original moon. It was arresting, partly because it had been so long since he had looked squarely at it, and so he stood there for a while observing. Peach Pit was still largely in one piece, but other than that the original Seven Sisters were no longer discernible.
Out of curiosity he consulted an app that told him when Izzy would be passing over, and saw that it was going to happen in about ten minutes. So he stood there and waited for it. As he waited, his attention turned again and again to the pieces of the moon. What was their future? He knew that they would shatter into an uncountable number of fragments and become the White Sky and then the Hard Rain. But what was the final distribution of sizes going to be, how many big ones and how many small? They had some models based on the simplifying assumption that all moon rock was basically the same, but clearly that wasn’t true.
They had done some analysis on the original chunks, trying to figure out why Peach Pit was so resistant to fragmentation, and determined that it was simply the inner core of the old moon. Which was confirmed anyway by an analysis of its mass: Peach Pit was much denser than the other bits, suggesting that it consisted mostly of iron as opposed to rock. The moon had had an iron core, but, relative to overall size, this was much smaller than the Earth’s; most of the moon was cold, dead stone.
And yet the core was there, and was thought to consist of a ball of solid iron surrounded by a somewhat hotter jacket of molten iron mixed with various other elements. All of this had been stripped bare and exposed to space by the Agent. For the first few hours, Peach Pit had literally glowed with radiant heat. Or so they guessed, since the dust kicked up by the cataclysm had cloaked it for a while. Some of the core’s outer jacket of molten metal must have been torn away, dispersed into the rubble cloud as gobbets and slugs and droplets of melt that soon cooled and hardened. As much was proved by metal-rich bolides that had since plowed into the Earth
and been dug up and analyzed. By the time the dust had literally settled to the point where Peach Pit and its siblings were clearly observable, an outer crust had formed over it, consisting of melt that had cooled swiftly as it radiated its heat into space. The cooling had continued ever since. Now, the better part of a year later, Peach Pit, or PP1 as it was now designated, was still warmer than the other parts of the moon. It had shown greater resistance to fragmentation. Other rocks bounced off it, or dashed themselves to pieces on its gleaming surface. A few significant chunks—PP2, PP3, and so on—had been ripped off in the early days when it had still been soft, but now it was clad in a mile-thick armor of solidified iron that was proof against just about any calamity short of a second Agent.
Doob became so absorbed in such thoughts that he almost missed the transit of Izzy across the sky. It angled directly over the rubble cloud, seeming to weave among the giant tumbling boulders, though this was of course an illusion. It had long been the brightest man-made object in the sky, and it was brighter now that so many pieces had been added onto it. The effort had been impressive. Stirring, even. But seeing it against the scale of the disaster behind it forced him to ask himself what was the point. What was the longer-term plan for the Cloud Ark? The swarm concept was a nice architecture, much more survivable than One Big Ship, but where was it going to go?
No one seemed to be talking about that. He understood why. Survival was the first imperative. Long-term strategy came next.
The amount of iron in PP1 was for all practical purposes infinite. It would take humans many thousands of years to find uses for that much metal.
But it was way up high. Hard to reach.
And yet they had to reach it.
And it was closer, easier to reach, than the Arjuna asteroids that Sean Probst was so excited about.
Feeling an idea take shape in his head, like an iron core congealing deep in a moon, he put it on hold and forced himself to turn his attention to more immediate questions. A few days ago in the Oval Office he had formed a resolve to get his ass into space and begin making things happen up there. Which was fine. But he had three months left on terra firma. He couldn’t neglect his responsibilities here. Some of which—the most important—were to his kids, to Amelia, and to their frozen embryo. But on top of that he had been given other jobs, and if he screwed them up badly enough, e.g., because he was standing on hotel balconies in the middle of the night thinking about how much iron was in PP1, then they might not send him up to the Cloud Ark at all. He hadn’t wanted to go, but once he had assented to the idea, he had begun wanting it more than anything, and he now feared that they would take it away from him. And if they sensed that fear, they could use it to control him. Better to overperform, to exceed expectations, to act like it was nothing at all.
SEVENTY-TWO HOURS LATER HE WAS LOOKING OUT THE WINDOW OF a U.S. Navy helicopter banking through a misty Himalayan valley as it lined up its final approach to a runway in Bhutan. Or perhaps the runway in Bhutan was the more correct phrasing.
There were about 750,000 people in this country, which meant that they were entitled to supply two candidates for the Cloud Ark. The arithmetic was a little fuzzy; if the same ratio were applied consistently all over the world, something like twenty thousand candidates would be gathered in. If an arklet could accommodate five people, then four thousand arklets would be needed in the swarm. Each arklet required a heavy-lift rocket to get it into orbit, and some assembly and prep work once it had reached Izzy.
Could it be done? If the entire industrial capacity of the world were thrown into the production of rockets, arklets, space suits, and the other goods needed? Perhaps. But probably not. Doob was privy to some recent estimates that put the numbers at closer to one-quarter of that figure.
And anyway, could the arklets really support five humans each? Without a doubt they were large enough for five people to bang around in, but it was not at all clear that each could be self-sufficient in food production. Building a sustainable ecosystem in a tube the size of a railway tank car was no small task. Biosphere 2, a well-known experiment in the Arizona desert, had attempted to support eight people on an ecosystem the size of a couple of football fields, and been unable to make it work long term. But its mission had been clouded by political strife and odd quasi-spiritual factors. A more down-to-earth project run by the Soviets had determined that eight square meters of algae—an expanse of pond scum about the size of two ping-pong tables—was needed to keep a single human supplied with oxygen. In the space between the hard inner hull and the inflated outer hull of a single arklet there was more than enough room. But much more real estate would be needed if the arklet were also to produce food. And those calculations didn’t even begin to address the real complications of keeping thousands of people alive in space for many years. It wasn’t enough just not to asphyxiate and not to starve. People would need medicine, micronutrients, recreation, stimulation. Ecosystems would get out of whack and need to be repaired with pesticides, antibiotics, and other hard-to-make chemicals. The thrusters that kept the arklets out of trouble would need to be refueled, and not only that but they would need maintenance and repair. The idea of a completely decentralized Cloud Ark was a chimera; it was not sustainable without a mother ship, a central supply dump and repair depot. The only plausible candidate for that was Izzy. But Izzy wasn’t designed for anything like that purpose. They’d been trying to make it over by cramming it with vitamins, but that only delayed the moment when they’d run out of all the goods they didn’t know how to produce in space, and people would begin dying in quantity.
From the fact that he had gotten nowhere raising awkward questions about this, Doob inferred that the Arkitects knew about it, and were on it, and just didn’t want to talk about it because public doubt and controversy were not going to help. Doob’s job, clearly, was to act like everything was okay. Today, that meant scooping up two young people from the Himalayan kingdom of Bhutan.
Did the little performance he was about to put on really mean that twenty thousand people from all over the world were going to end up living happily in the Cloud Ark? He just had to shut down the little Rain Man in his head—“Doob, as in dubious”—and not even think about it.
They had taken off two hours ago from the George H. W. Bush, a supercarrier keeping station in the Bay of Bengal. Doob had viewed the ship through the eyes of a man who, in a few months, would be making a permanent move to its orbiting equivalent. She was a completely artificial island, thousands of people densely packed into a wad of pure technology. The professionalism of the crew and the efficiency with which she ran were amazing. Could something like that be duplicated in space, with people chosen by lot from all over the world, and trained in camps over the course of a single year?
He reckoned he would know more in about half an hour.
The navy chopper plunged into a fog-stuffed slot between mountains and knifed through steam and mist for a few minutes. The airport’s sole runway came into view, startlingly close to them. The chopper flared to a perfect landing a stone’s throw from the terminal building. Doob became aware that his jaw was clenched, and tried to relax it. He had made the mistake of googling this place and learned that it was bracketed by eighteen-thousand-foot mountain peaks, that only eight pilots in the world were certified to land here, and that even they didn’t attempt it unless the sun was shining on the runway. Obviously the kinds of guys who flew choppers for the navy operated according to different rules, but it had still been a white-knuckle approach as far as Doob was concerned, and it made him wonder how he was going to react to being hurled into space on top of a hastily constructed tube full of explosive chemicals.
He shifted in his seat and felt a thick manila envelope slide out of his lap and to the deck with a solid thunk that almost woke up Tavistock Prowse. Tav had been sitting across from him for the entire duration of the flight, and had been sleeping for the last half hour—prostrate from jet lag. He was a bulky man, not especially tall, but cons
tructed like a wrestler. The bald spot on the back of his head, which had been faintly visible even when he’d been in college, had expanded mercilessly, leaving just a monklike fringe of close-cropped hair around the back of his bullet-shaped head. Perhaps to draw attention away from it, he wore glasses with massive black frames. At one point a serious weight lifter, he had softened and spread in the last decade, and even more so since Zero. It was strange in a way to see him unconscious, for he never seemed to stop moving.
Doob had a pretty good idea why. Tav was hoping he’d get picked. If he worked hard enough, popped up on enough news feeds, garnered enough followers on Twitter, maybe some important person would decide that the Cloud Ark needed a professional communicator—the first, or the last, journalist. To Doob it seemed like long odds. A lot of people with Ph.D.s and even Nobel Prizes were ahead of Tav in line. But you never knew. And he couldn’t fault the guy for trying.
He bent forward and retrieved the envelope from the deck. It was a centimeter thick. It was labeled PARO, BHUTAN in neat block letters. The flap had never been opened. He was supposed to have spent the last couple of hours reading its contents, familiarizing himself with the task to be performed. Instead of which he had been looking out the window at the steamy green plains and lazily braided rivers of Bangladesh.
Hoping to make the most of the two or three minutes it would take to get the chopper’s door open, he plucked it up off the floor, tore it open, and pulled out a sheaf of pages. This was enough to wake Tav up, but not enough to make him move. He gazed at Doob and watched him read.
“If it’s wearing red, yellow, or both, it’s a lama,” he said. “Bow to it.”
“Isn’t that a camel from South America?”
“With one L. A holy man. Put the palms of your hands together and make a little bow.”
“I don’t believe in—”
