at Caltech, and from the other labs doing the same calculations at other universities around the world, were that the White Sky would happen on or about A+1.354, or one year and 354 days after the breakup of the moon; they were one-fifth of the way there).
The purpose of the Scouts—the first wave of what amounted to suicide workers such as Tekla, who had arrived starting on Day 29—had been to build out the improvised network of hamster tubes and docking ports that would make it possible for a much larger population of so-called Pioneers to reach Izzy. The basic distinction between a Scout and a Pioneer was that the Scout went up knowing there was no place to dock, but the Pioneer knew that, at least in theory, there would be an available port for their spacecraft, with pressurized atmosphere on the other side of it. The promise had failed in one case, with the result that half a dozen Pioneers crammed aboard a Soyuz had silently asphyxiated. The problem was traced to a defect in a hastily built docking mechanism. Three Chinese taikonauts lost their lives when the hamster tube in which they were moving was pierced by a micrometeorite and lost pressurization. But from about Day 56 onward, Pioneers were arriving at a rate of between five and twelve per day. There was a lull once all the available docking spaces were occupied, but after that it began to snowball as spacecraft began to dock to other spacecraft, and the hamster tube network was built out, and inflatable structures were deployed.
Izzy, which had been a complicated and hard-to-understand contraption even before all of this had happened, was now an utterly bewildering maze of modules, hamster tubes, trusses, and ships docked to ships docked to ships, “like a freakin’ three-dimensional domino game,” as Luisa put it. The only way to get one’s bearings, looking at a rendering of the complex, was by picking out the rugged and asymmetrical shape of Amalthea at one end and the two tori at the other. Those were “forward” and “aft,” respectively, and the axis between them was the basis for the traditional nautical directions of “port” and “starboard” as well as “zenith” and “nadir,” which were space lingo for basically “up away from Earth” and “down toward Earth.” If you arranged yourself so that your back was to the tori and your face toward Amalthea, with the “port” stuff on your left hand and the “starboard” stuff on your right, then your head would be aimed toward the zenith and your feet toward the nadir and the surface of Earth four hundred kilometers below.
That, however, was the privileged view of people outside the thing in space suits. Inside, it was still easy to get lost in the three-dimensional domino game. Felt-tip markers, always a scarce resource even on Earth, became objects of great value as people used them to mark directions on the walls of hamster tubes and habitat modules.
“IT’S JUST A CHRONOLOGICAL ACCIDENT THAT I’M HERE AT ALL,” IVY mused, during one of her and Dinah’s increasingly rare drinking sessions. All of their original stashes of booze had long since been consumed, but new arrivals were kind enough to slip them bottles from time to time.
“I disagree,” Dinah said. It wasn’t exactly a scintillating response. But she’d been caught off guard by the suddenness with which Ivy had dropped her guard.
“If the moon had blown up two weeks later, some Russian sourpuss would be in charge up here and I’d be on the ground, married and pregnant.”
“And under the same death sentence as everyone else.”
“Yeah, well, there’s that.”
Dinah reached for the bottle and refilled the shot glasses, trying to stretch out the moment. It had never been easy to get Ivy to open up, even back in the happy days before Zero.
“Look, Ivy, it’s not an accident that you were in charge of Izzy. They gave you the job for a reason. You’re the last girl in the world—or out of it—who should be suffering from impostor syndrome.”
Ivy stared at her through a somewhat amused silence. “Go on,” she finally said. “What is this impostor syndrome you speak of?” For they’d talked about it before—but usually with Dinah being the one who felt it.
“Don’t try to deflect this. What’s going on?”
Ivy glanced at the ceiling: a sort of visual signal, borrowed from the Russians, to remind Dinah that you never knew when someone was listening. Then she looked into Dinah’s eyes. But only for a moment. She was fundamentally a shy person, who preferred inspecting her shoes while baring her soul.
“You and Sean Probst made great sparring partners,” Ivy said.
“He was so fucking obnoxious! He needed someone to—” Dinah cut herself short then, because Ivy had gotten a sort of sad, wry look on her face and held up one hand to stop her.
“Agreed! Yes. Thanks for doing it,” Ivy said. “He needed someone like you around. Sometimes it almost looked like a comedy act between you two. And the way that the Russians reacted to him—Tekla first of all, of course, but later Fyodor proposing to place all Arjuna personnel under arrest and confiscate everything they’d brought up with them—that was great drama. Tabloid stories and comment threads galore down on the surface. But I barely survived it.”
“What do you mean, you barely survived?”
“You wouldn’t believe some of the conferences I had with Baikonur and Houston. People down there wanted me to take a very hard line. To do what Fyodor wanted.”
“But you didn’t,” Dinah pointed out.
Ivy met her gaze again. Then, after a moment, she gave a little nod.
“So you won,” Dinah went on.
“I won a Pyrrhic victory,” Ivy said. “I negotiated a less draconian solution. The Ymir expedition went on its way with no obvious hard feelings.”
“And how is that Pyrrhic?”
“I don’t want to make my problems yours,” Ivy said.
“Who else are you going to talk to?”
“Maybe no one,” Ivy returned, showing a flash of something like anger. “Maybe that’s what a leader is, Dinah. The one person who can’t—who shouldn’t—share her problems with anyone else. It’s sort of an old-fashioned idea. But the human race might need such people going forward.”
Dinah just stared back at her. Finally, Ivy relented, and spoke in tones almost devoid of feeling: “My position as the head of the space station came under serious challenge. It made me aware of politics on the ground that have been going on for some time—but that were invisible to me until the Sean Probst controversy surfaced them. Since then, I believe that my authority has been further undermined by people on the ground, leaking things to the press, saying things in meetings.”
“Pete Starling.”
“No comment. Anyway, I think I am going to be replaced before long.”
Ivy’s eyes had reddened slightly. She made another glance at the ceiling, but the expression on her face suggested she didn’t care who might have heard her. Then she looked at Dinah and smiled. “How have you been doing, sister?” she asked in a weak voice.
“I’ve been pretty good,” Dinah said.
“Really? That’s music to my ears.”
“Bo, Larz, the others who’ve come up to work in my crew, they seem to respect what I’ve done,” Dinah
