The Cloud Ark passed through a complete day/night cycle every ninety-three minutes. Time was arbitrary in space, so the ISS had long ago settled on Greenwich time, also known as UTC, as a reasonable compromise between Houston and Baikonur. The Cloud Ark had inherited that system, and Day 700 began at midnight at the Royal Observatory in Greenwich, or A+1.335.0 in ark time. About one-third of the population woke up to begin a sixteen-hour shift. Others would wake up at A+1.335.8, or “dot 8,” and at “dot 16.” The system ensured that about two-thirds of the population was awake at any given time. Awake people needed more oxygen and generated more heat than sleeping people, so it put less of a strain on life support systems, and enabled the Cloud Ark to support more people, if the waking and sleeping cycles were staggered. A reason for the popularity of triads was that each of the three component arklets could operate on a different shift, observing its own artificially imposed period of darkness and quiet. In a heptad, the same basic scheme could be used, with two of the arklets asleep at any given time and the one in the middle of the hexagonal frame being “always on.”

Doob had requested, and been granted, a position in the third shift, meaning that he was basically operating in the same time zone as Amelia, Henry, and Hadley on the West Coast of the United States. He had awakened at dot 16 of the day before, or four in the afternoon in London, which was eight in the morning in Pasadena. So, at the stroke of A+1.335.0, when the first shift of that day began, he had been awake for eight hours and was feeling like a brief nap might do him good. But he knew that this would only make it more difficult to get to sleep at dot 8 and so decided, as usual, to gut it out.

Finding that his brain was too addled to make any sense of the latest figures from Caltech on the continued exponential breakup of moon debris, he went to the “gym,” which was a module containing several treadmills. To prevent their users from bouncing off them in zero gravity, these were equipped with waist belts and bungee cords that held the occupants “down,” pressing their feet against the belt of the treadmill and forcing the legs to do some real work. Supposedly it was good for the bones and muscles. Amelia kept sending Doob emails asking him whether he’d exercised today, and he liked to make her happy by answering yes.

A few minutes after he began his exercise routine he was joined by Luisa Soter, who had just awakened, as she was on the first shift. She liked to do her “jogging” first thing in the morning, so it was not the first time they had intersected in this way. Six treadmills had been mounted to the walls of this cylindrical module; the users’ feet pointed outward and their heads projected in toward the center like spokes converging on a hub, bringing them rather close together and making conversation easy. For extroverted, social people like Doob and Luisa, this was a great setup; more solitary exercisers would don headphones and pointedly focus on a tablet or a book.

“Did you go to Venezuela when you were out collecting Arkies?” Luisa asked him.

The way she stressed the word “go” suggested that Venezuela was an obvious topic of conversation — the thing that well-informed persons would naturally begin talking about first thing in the morning. Doob didn’t know why. He had heard a few people talking recently about Kourou, which was the place in French Guiana where the Europeans, and sometimes the Russians, launched big rockets into orbit. In the last two years it had become one of the most important launch sites for arklets and supply ships. So he had the vague sense that something was afoot there, something that people were concerned about.

He had been focusing all of his attention in the other direction, on Peach Pit and its iron-rich “children.” These were still visible, through increasingly thick clouds of rocky debris. When the White Sky happened they would vanish into a cloud of dirt, and he might not see them for a while. So he had been looking at PP1, PP2, and PP3 while the looking was still good, nailing down their exact orbital parameters, taking high-res photographs. PP3 was especially interesting. It was a congealed glob of mostly iron, similar in composition to Amalthea. It was some fifty kilometers in diameter. And it had a deep cleft on one side, comparable in size to the Grand Canyon, apparently formed by a collision that had rent its outer skin while it was partly congealed. Doob had begun calling PP3 Cleft.

“Doob? You still with me?” Luisa asked. “I was going to say ‘Earth to Doob, Earth to Doob,’ but it doesn’t apply anymore.”

“Sorry,” he said. He had gone into a reverie thinking about that huge crevice on the side of Cleft, imagining what it must look like from the inside. “What was your question again?”

“Venezuela,” she said. “Did you do any of your ‘abduction runs’ there?”

“No,” he said. “Closest I came was Uruguay. Which isn’t that close. And by that time I was pretty burned out.”

“Why were you burned out?”

Typical Luisa!

“Overscheduling?” she went on. “That is, was it physical burnout? Or more emotional/spiritual?”

“I had just had it,” he said. “It’s hard. Taking young people — the best and the brightest — away from their families.”

“But it was for a good purpose, right?”

“Luisa, where are you going with this?”

“Are you aware of what is going on offshore of Kourou?” she asked in return.

“No,” he said flatly.

“You’ve checked out,” she said.

“I talk to my family every day. But other than that? Yes, Luisa, I have checked out of planet Earth. Nice place. Lovely people. But I have to focus on what comes next.”

“So say we all,” she said. “But one could argue that things happening in Old Earth’s final three weeks could have repercussions on New Earth.”

“What’s going on?” he asked.

“Apparently not a single one of the seventy-five Venezuelans who were picked in the Casting of Lots has actually been sent into space,” she said.

“You know that the overall ratio has ended up being something like one in twenty,” Doob said. Meaning that for every twenty candidates chosen in the worldwide Casting of Lots and brought to the training centers, only one had found a place up here in the Cloud Ark. Not a figure to be proud of. But it was the best they’d been able to do, and they hoped to bring the number down to more like one in fifteen, or even one in ten, with a last-minute surge of launches.

“Yes. And the Venezuelans know that too. So they’re saying that three or four of their seventy-five ought to have made it up here by now.”

“Statistically, that is not a valid—”

“These people do not look like statisticians.”

“Politics.” Doob sighed.

Luisa chuckled. “I hear you, sugar. I’m not gonna say you’re wrong. But I have to warn you that this is the word—‘politics’—that nerds use whenever they feel impatient about the human realities of an organization.”

“And I’ve been in enough faculty meetings at Caltech to know how right you are,” Doob said. “But I meant it in a different way. The way that the Venezuelans ran their selection program was overtly political. In most countries they took the Casting of Lots idea with a grain of salt. There was a random element, yes — but they also filtered for ability. The Venezuelans chose not to do that. So, they ended up sending in kids from the boondocks, truly chosen at random. Many of whom had fine personal qualities. If I had my way, we’d get some of them up here. But I’m not the one who is choosing. The people who are, are choosing on the basis of math ability and things like that. So it makes me sad that other people are in line ahead of the Venezuelans, but it doesn’t surprise me.”

“Three weeks ago, boat people started squatting on Devil’s Island,” Luisa said, “refusing to move.”

“Isn’t that a penal colony?” Doob asked. “Why would anyone—”

“It used to be a French prison, yes,” Luisa said. “Hasn’t been for a long time. Hardly anyone lives there. But it’s right under the flight path for launches out of Kourou. So, whenever there’s a launch, they evacuate it.”

“It must be evacuated all the time then, given the amount of traffic.”

“For the last two years, yes. But then a bunch of people showed up there and camped out and refused to move.”

“I’m guessing that the French and the Russians went right on launching.” In fact, Doob knew as much, since he saw arklets and supply ships coming up from Kourou all the time.

“Yes. So the occupation was more of a symbolic gesture at that point.”

“These squatters were Venezuelans, I take it.”

“Yes. It is a fairly easy cruise along the coast from Venezuela to French Guiana — a few hundred kilometers.”

Something was itching in Doob’s memory. “Does this have anything to do with the supply vessel that failed to show up yesterday?”

“And the day before. There’s been a two-day interruption, going on three, in launches out of Kourou.”

“A few squatters on Devil’s Island can’t explain that,” Doob said. Then he added, as a joke, “Unless they have surface-to-air missiles.”

Luisa said nothing.

“Are you shitting me?” Doob said.

“It’s not so much the ones on Devil’s Island as the ones in the blockade,” Luisa said. She handed her tablet to Doob. She’d pulled up what looked like an aerial photograph, probably shot out the window of a helicopter. In the foreground was the European Space Agency launch complex, which he’d seen before. It was separated from the Atlantic by a couple of kilometers of flat ground, banded with low, scrubby beach vegetation. In the distance was a trio of small islands, a few miles off the coast; he assumed that Devil’s Island was one of them.
