“This is Day Thirty-Seven,” Ivy went on. “That’s ten percent of a year. If it’s true that we had two years from Zero to the Hard Rain, then we have already burned through five percent of the time during which we can expect to receive any help from Earth. Five percent of the time needed to turn this installation into a society and an ecosystem that is sustainable indefinitely.”
Ivy was standing with her back to the big screen, so she couldn’t see the reaction of the Arkitects down below, in some conference room at the other end of the video link. For today’s meeting, there were three of them: Scott “Sparky” Spalding, who was still the administrator of NASA; Dr. Pete Starling, the president’s science advisor; and Ulrika Ek, a Swedish woman who had worked as a project manager for one of the private commercial space startups until recent events had forced a career change: she was now coordinating the activities of several different space agencies and private companies as they worked on the Cloud Ark. Apparently, she had become the Arkitect-in-chief.
“Apparently” being the key word, since every time Dinah had any contact with the ground she was reminded of how little she understood of what was happening there. On one level she was one of the luckiest people in the human race. She was going to get to stay alive. At the same time, she and the others got very little information from the planet, and had to piece things together from a jumble of clues.
She’d compared notes on this with Ivy, who had confirmed that even she had little to go on, and what she did hear contradicted itself from hour to hour.
It had all become Kremlinology. Back in the heyday of the Soviet Union, the only way for Westerners to guess what was going on there was to look at the lineup of dignitaries on Lenin’s Tomb in the May Day parade, and riddle it out from the seating chart and who shook hands with whom. Now Dinah was doing the same thing with these three faces on the screen. Sparky was no use. He’d spent so much time in space that he had developed a kind of thousand-light-year stare. He was famous for being oblivious to the political side of things.
His opposite in that respect was Pete Starling. Pete’s job was to mutter scientific explanations into the president’s ear. He’d been doing rather a lot of it in the last thirty-seven days. He had a background running big science programs at universities, climbing the ladder from Mankato State to Georgia Tech to Columbia to Harvard in a mere ten years. Why was he sitting in on this meeting? There was little he could contribute. He must be here as the eyes and ears of J.B.F.
But why should J.B.F. care? No decisions were going to be made here; it was just a status report, a check-in.
As soon as Ivy finished her sentence, the corners of Pete’s mouth turned down. He looked at Ulrika Ek, a somewhat matronly woman in her late forties, extremely good at her job, according to Rhys. On the high-def video feed, Dinah saw the slightest deflection of her eyes, noticing the turn of Pete Starling’s head, but not exactly acknowledging it.
Ulrika clearly didn’t like him. But there was a reason she was a well-regarded project manager. “Ivy,” she said, “just for clarity, when we speak of ‘this installation’ we’re using the term in an elastic sense. Of necessity.”
Ivy turned to look at the screen. “‘Installation’ probably isn’t the right word,” she admitted. “Since it’s not installed anywhere.”
Pete Starling spoke up. “I believe that where Ulrika is going is that the Cloud Ark is a fluid concept that may paradigm-shift beyond recognition as we proceed adaptively through the next ninety-five percent of the timeline.”
Ivy’s brow furrowed. Something was going on, some kind of political tussle down on the ground. It was important to people like Pete.
“This is not efficient use of time,” Fyodor said. “I am working to extend truss to receive Pioneers.” Fyodor’s English was excellent, but when he was annoyed, as he was now, he dropped his articles. “I have eight suits outside, five inside, for unlucky number of thirteen.”
It had become common to use a form of synecdoche in which “suit” denoted “a person qualified to perform extravehicular activities who is equipped with a space suit that still works.”
“Pioneers arrive in two weeks, this is still true? Then I need more Scouts yesterday, as saying goes.”
When Fyodor had come up to Izzy six months ago, it had been understood as a valedictory mission before getting shunted to an administrator’s job at Roskosmos. Not that he hadn’t taken his duties seriously, but he always seemed to be taking the long view, perceiving Izzy through the eyes of a future bureaucrat who would need to make it run smoothly until his retirement. That had all changed on Zero, of course. It had changed even more with the Russian invasion. No new rank or title had been bestowed on Fyodor. None was needed. All the Russians just accepted him, implicitly and without question, as their leader. And his manner had changed accordingly. He was scrupulously respectful of Ivy’s authority, but there was no question that he was the boss of all things suit related, and the authority had seemed to make him physically larger and more imposing, his creased face tougher, his voice firmer.
Sparky answered him. “Fyodor, that fuel pump has been fixed. It was just a bad sensor. So the launch is going up as scheduled . . .” He checked his wristwatch, did a mental calculation. “Fourteen hours from now. Six hours after that, you’ll have your suits.”
“And the Zavods, the Vestibyuls—the things I mentioned.”
“We have had teams of engineers working on those fixes around the clock, Fyodor.”
“I am very worried about door closing mechanisms.”
THE REMAINDER OF THE MEETING HAD TO DO WITH THE PIONEERS who would start coming up in another two weeks, and who would live, for the time being, in rigid or inflatable habitats more accommodating than Luks. These would be docked along a series of pressurized tubes, little different in principle from the big spiral-wound ventilation ducts seen in warehouses, that would ramify outward from attachment points in the truss. Little of it concerned Dinah and so her attention drifted to her laptop. She had other things she could be working on, and Ivy’s reminder about the 5 percent had not left her in a mood to woolgather during a long meeting.
Most of her work of late had been on ice crawlers. And, as of the most recent shipment, ice tunnelers. But she had resolved that she would not shut down her progress on the iron-mining robots. Even if she only spent fifteen minutes a day on them, it was better than suspending work altogether. She was afraid that if she ever did that the entire project would disappear.
To that end, she kept a window open in the lower left corner of her screen, showing video from Amalthea, mostly the point-of-view cameras of robots that were actually doing things. It was always there in her peripheral vision as she attended to email and scheduling spreadsheets and Gantt charts.
And at some point she noticed something that wasn’t quite right. A few minutes later, she noticed it again and put her other work on hold. She expanded the window and took control of the robot that was transmitting the video. She swiveled its camera around until she had a view of the thing that had been bothering her.
It was Tekla, floating in her Luk. She was bright blue, which meant that she had donned her cooling garment. That was normal. She did it every day as she got ready for her shift. The next step should have been to squirm feetfirst through the Luk’s flange into the Vestibyul. But she wasn’t doing that. She was going back and forth between the Vestibyul and the middle of the Luk. She would go through the flange headfirst (which was abnormal) and do something for a minute or two, then withdraw into the Luk and thumb away on her tablet for a while.
She was late. Every other day, she’d been in her suit and out on the truss by this time.
Dinah wasn’t the only person who had become distracted by her laptop. Fyodor—normally not a fan of email and other such modern diversions—was watching his screen too, occasionally making eye contact with the equally distracted Maxim, who kept making a gesture like tugging at an imaginary beard.
Something was wrong.<
br />
What had Fyodor said? I am very worried about door closing mechanisms.
He wasn’t just saying that in the abstract. He was referring to a specific situation. He was talking about Tekla.
Tekla could clamber from her Luk, through the Vestibyul, and into her suit, but she couldn’t close the door behind her back. She needed the mechanism for that. If it didn’t work, then she couldn’t seal the suit. And if the suit wasn’t sealed, she was trapped inside her OVL (as they had taken to calling the combination of the Orlan suit with the Vestibyul and the Luk).
It was not exactly an emergency, but it was bad. In order to get “mail” she had to detach her suit from the Vestibyul, leaving it open for the delivery to be made in her absence. “Mail” included food, water, ice, and fresh CO2 scrubber canisters.
Dinah didn’t know how long Tekla could survive without “mail,” but she doubted it was more than a day. The heat would get her first.
They had to figure out some way to get Tekla inside Izzy. And since the OVL was jury-rigged, it didn’t have a docking port like a normal spacecraft. There was no hatch, no way of mating to an airlock.
She studied Fyodor’s face through the rest of the meeting, which went on for another half hour, and began to understand something: he was getting ready to sacrifice Tekla. “Ready” in the sense of emotionally hardening himself to that reality.
Dinah understood NO EMAIL now. It was simply part of being a Scout that you would probably not survive. And if you knew you were going to be sacrificed, it wouldn’t help matters to be spamming the Scout email list with pleas for help and goodbye messages. Tekla could communicate with Fyodor, and Fyodor only, and that was for a reason. It was a reason that the defenders of Leningrad, Stalingrad, and Moscow would have understood and accepted perfectly well. But it was a little bit out of step with the modern ethos.
Correction: with the modern ethos as it had existed during the Age of the One Moon.
It was perfectly in step with how things were now.
Part of her wanted to go and plead with Fyodor to mount a dramatic and heroic rescue mission. There had to be a way to make it happen. They had all seen Apollo 13, they quoted lines of dialogue from it all the time.
But she already knew the answer. The Pioneers would begin arriving, shiploads of them, in two weeks. All of them would die on arrival if the correct preparations had not been made. No time could be spared. More Scouts were on the way to replace Tekla.
And for once she was glad that the meeting ran long, that Sparky didn’t stick to the agenda, and that Pete Starling exploited it to fill time with more buzzwords. Because an idea was slowly taking shape in her head. She would have to run it by Ivy and Rhys and perhaps Marco, she would want to have Margie Coghlan—the closest thing they had to a doctor—standing by, but she could do it with no help at all from Fyodor or any of the other suits.
Fyodor was typing something with his index fingers. She locked her eyes on his face and kept them there until he was finished. He seemed to have detected her gaze on him, because he then looked up and stared straight into her eyes, maintaining a perfect poker face.
She stared back.
Awareness crept into Fyodor’s expression. Awareness that Dinah knew about the problem. Fyodor knew the layout of Izzy better than anyone. He knew where Dinah spent her time, and that Dinah only had to look out her window to see what was going on. She could see him putting this all together in his head.
He was expecting her to make some emotional appeal. So, it was important for her to stay cool. As soon as she turned on the waterworks, she would lose his respect, and his attention, forever.
“Fyodor,” she said, “I got this.”
He blinked in surprise, then, after some hesitation, made the tiniest of nods.
“Got what?” Pete Starling asked, over the video link. “Am I missing something?”
“No,” Dinah said. “We are just proceeding adaptively to leverage our core competencies.”
BASED ON STATS FROM THE 50 HOTTEST OLYMPIANS WEBSITE, IVY WAS a fairly close match for Tekla physically. Tekla was huskier, but Ivy was an inch taller. So, the first thing they did was to stuff Ivy into the small airlock that Dinah used for her robots. With her head tucked and her knees drawn up to her chest, she fit into it with room to spare. Dinah took a picture, then appended it to an email message with detailed instructions.
Spencer Grindstaff, who, as a young CIA contractor, had cut his teeth hacking into email systems operated by foreign governments, figured out a way to send email to Tekla’s tablet by wrapping it in an envelope that made it look like it came from Fyodor.
Dinah watched Tekla read that email. She looked up from the tablet toward the window, then turned her gaze toward the airlock. Until then, Dinah had worried that Tekla might be losing consciousness, since she hadn’t moved in several hours. She guessed that Tekla was trying to conserve oxygen and reduce thermogenesis by moving as little as possible.
Dinah zip-tied a high-powered LED light to the inner hatch of the airlock, then closed it. She opened the valve that dumped its air into space, allowing it to “fill up” with vacuum, and then actuated the lever—a simple mechanical linkage—that flipped the outer hatch open. She could see the white glow of the LED reflecting against the plastic of Tekla’s Luk bubble a few meters away, and she saw Tekla’s head turn as the light got her attention.
Several robots had to act in concert to move Tekla’s Luk bubble around until it was pressed against the airlock. This was a somewhat maddening process, like trying to grab an inflated balloon with a pair of needle-nosed pliers. Dinah had been trying to do it with Siwis—Sidewinders—of which she now had a dozen in operation. A Siwi could join head-to-tail with another Siwi to double its length, and the process could be repeated indefinitely to construct a sort of smart, instrumented tentacle. By planting the tail of one Siwi against Amalthea, and bolstering the connection by holding it down with a couple of anchored Grabbs, she was able to make another Siwi slither up the first one and connect to its head, which was projecting up into space. A third Siwi climbed up the first two and concatenated itself, and so on and so forth, building a stalk that reached up from the surface of the asteroid and began to curve around the bubble in which Tekla was imprisoned.
So far so good. But the longer the chain grew, the worse it behaved. The Siwis were constructed like caterpillars, consisting of many identical segments connected by flexible joints. The joints were motorized, and the motors were supposed to follow commands embedded in Dinah’s code, and it was all supposed to work in a predictable way. The problem was that each joint had a bit of flexibility, which as far as Dinah was concerned was error. Those errors accumulated as the length of the chain grew, so that by the time she had connected three Siwis together, she found it difficult to know, let alone control, the position of the end of the stalk. And when she tried to apply force by making the chain curve around the slippery, bulgy surface of the Luk, matters only got worse.
Rhys showed up a few hours into the project and watched. He’d be silent for hours, then suddenly ask a question that was strangely off-kilter and yet showed he was thinking about the problem.
“What if you turned all the motors off and let the whole thing go slack?” he asked.
“Aren’t you supposed to be building a torus?” she demanded, and turned around to give him her best attempt at a killing look.
“First we have to solve this problem,” he said gently.
She had more to say, but instead she went silent. Rhys was clowning around with his necklace again. He was in the habit of wearing a chain around his neck—nothing fancy or bulky, just a simple loop of twisted-link jewelry chain in stainless steel, which he used as a way to keep thumb drives and other important small objects from floating away. At the moment, though, he had removed all of that stuff, leaving the chain unencumbered, and he had got it spinning around his neck. It had opened up into a broad, undulating oval that didn’t touch his neck or collar anywhere, so it
was just orbiting around him in free space. Dinah had seen him do this before, typically while bored in meetings. He had learned a few tricks for speeding it up and coaxing it into different shapes by blowing on it with a drinking straw or flicking it with a fingernail. It didn’t form a perfect circle, as one might expect. The moving train of links could be molded into almost any shape, and would stay that way until disturbed. When Dinah turned around and noticed he was doing it again, she was about to roll her eyes and say something like For fuck’s sake can’t you do anything useful with that brain, but the look on Rhys’s face suggested that he was up to something more than just playing around.
The chain had been running in an elongated racetrack shape, nearly buzzing his neck on one turn, but he flicked at the straightaways and broadened it into something approaching a circle, then ducked out of it, leaving the loop spinning in midair. “Channeling the wisdom of my ancestors, if you must know,” he said.
“You had ancestors in zero gee?”
“Alas, no. My great-great-great-great-uncle John Aitken was an eccentric Victorian meteorologist with an even more eccentric hobby: studying the physics of moving chains. Unfortunately for him, he had to do it in his drawing room in Falkirk, where there is, I’m sorry to say, gravity. He had to approximate this sort of thing”—Rhys nodded at the whirring loop of chain—“by building exceedingly clever machines.”
“Then he must have been a clever man indeed.”
“Fellow of the Royal Society and friend of Lord Kelvin, since you mentioned it. Do you see where I’m going?”
“Well, a minute ago you gave me a fat clue by suggesting that I turn off all of the motors in the Siwi train. Were I to do that, it would go completely limp and become, for all practical purposes, a length of chain.”
“Yes,” Rhys drawled, and poked an index finger up into the chain’s path. It caught on his knuckle, hiccupped, and suddenly wrapped around his hand in a chaotic tangle.
