Seveneves: A Novel (26 page)

The problem with crying in zero gee was that tears didn’t run down your cheeks. They built up in jiggling sacs around your eyes, and you had to shake them off or dab them away. Dinah didn’t have anything to dab with—the plastic coveralls they wore were notoriously nonabsorbent—and so she just drifted in the bottom of the arklet, looking at the light from the control screens through bags of warm salt water.

“Some assistant you are!” Ivy called back, after letting her go on for a few minutes.

“Sorry,” Dinah blurted out. “That was mission critical.”

“Try not to short out any of the equipment. Tears conduct electricity.”

“I think they made it all pee-proof. Remember, these things are designed for amateurs.”

“Tell me about it,” Ivy snorted. “The user interface is so easy to use, I can’t do anything.”

Something light whacked into Dinah’s head. Through the tears she vaguely saw a white object caroming off the nuclear reactor’s user-friendly control panel. Pawing it out of the air, her hands recognized it as a packet of tissues. A high-value black market item. She tore it open, pulled out a few sheets, and began the somewhat delicate process of soaking up the tear-globs without smashing them into sprays of equipment-shorting droplets.

“I mean, my God, what would Markus think of you?” Ivy demanded.

It took Dinah a few moments to catch up. “Him and me? You think?”

“It is so obvious.”

After a thrilling first few weeks, things had kind of trailed off with Rhys. It was okay. Easy come, easy go. She had never seen him as a stable long-term prospect. The times they’d been living in, and the place they’d been living, weren’t really conducive to long-term pair bonding. Luisa, wearing her anthropologist hat, had watched the spontaneous, mostly short-lived couplings of Izzy’s inhabitants with a combination of dry amusement, scientific fascination, and frank, hilarious envy.

“I don’t know,” Dinah said, “I see where you’re going, but he seems a little Captain Kirk.”

“You need a little Captain Kirk in your . . .”

“In my
what
?”

“In your
life
. Rhys is too introspective.”

“Is that a euphemism of some kind?”

“He’s depressed.”

“Gosh, I wonder why.”

“No, not that way. Not about the world ending and everyone
dying. I mean that when he’s working on a project he’s full of energy but when it’s finished he just kind of collapses.”

On the tip of Dinah’s tongue was a remark about how well that observation aligned with Rhys’s lovemaking style, but she held back. “You realize that all of this is being recorded?”

“Get used to it,” Ivy said, and Dinah could sense her shrug from twelve meters away. “Hang on, gonna give the forward thrusters a little pop—backing out of our parking space.”

She wasn’t kidding. The thrusters gave off something very like a bang when they went off. Dinah, who actually wasn’t hanging on, felt a few moments of disorientation as the whole arklet moved backward around her while she remained motionless. The green grid dropped away from her and the front door approached—but all so slowly that she needed only to reach out and glide a hand along the ladder to control her relative motion. In a few seconds the forward end of the arklet reached her and she stopped herself against one of the struts of Ivy’s couch. Next to it was a knot of straps and pads, like a rock-climbing harness, which Dinah now spent a couple of minutes untangling and climbing into. The bangs of the thrusters, the hisses and clicks of the associated plumbing, and Ivy’s murmuring into the microphone served as accompaniment while she got herself strapped in and donned a headset of her own. That enabled her to hear the clipped military-style transmissions among Dinah, Markus, and their controller on Izzy. An engineer in Houston weighed in every few minutes with questions and observations.

Once they had drifted well clear of Izzy, they initiated a programmed burn a few seconds long that took them to a slightly higher orbit. For a while they could see nothing but empty space through the windows. The sun must have risen over the Earth’s limb, because bright round spots appeared on the wall.

Ivy said, “I have Three on radar and am engaging MAP.” That being the three-letter acronym for Monitored Autonomous Piloting. The operation they were about to perform—the High Five—was
deemed way too ticklish to be handled by noob spaceship pilots. It had to be a robotic operation the whole way. But the algorithms, and the sensors that told them what was happening, were all brand new, so experienced pilots had to sit at the controls, watching through the window and taking over if and when the robo-pilot started acting screwy.

The thrusters began to pop in a different rhythm, a patter of tiny firings very different from how a human being would operate them. The star field swung past the windows, the splotches of sunlight veered around the walls, and suddenly Arklet 3 rotated into view, a few hundred meters away. It too was flying under MAP, coming about until its front door was aimed their way. Dinah stifled the impulse to wave at Markus and Fuhua. It was unprofessional, and anyway they wouldn’t be able to see her through the tiny porthole.

A spindly white arm swung outward from the side of Arklet 3 and locked into position, extended off to one side. A few moments later they heard and felt their own arm actuating likewise, and watched an animation of it on a flat screen.

“Bringing up the Paw camera,” Dinah muttered, and tapped a control that flooded a screen with high-resolution video from a telephoto lens mounted at the end of the arm. This showed nothing, at first, but the blue limb of the Earth’s atmosphere down in one corner. Then a targetlike pattern veered across the screen, slowed, and veered back. All of this was accompanied by more fidgety percussion from the thrusters. The feed was remarkably close, and clear. Comparing it to the direct view out the porthole, Dinah could see the target on the end of Arklet 3’s extended arm, looking tiny from this distance. But the machine vision system now in control of their little spacecraft had found it, and recognized it, and . . .

“We have a lock,” Ivy said. “We see you, Three.”

“We see you, Two,” Markus answered. “It proceeds.”

It proceeded with a longer firing of the aft thrusters that nudged them forward enough that Dinah could feel the pressure on her
bottom, sense the straps of the harness tightening. The target flailed around some, but a few moments later, the lock was reestablished. Dinah could see Arklet 3 growing larger. Numbers on a screen, gauging the distance between the ships—or, to be precise, between the two ships’ outstretched Paws—were counting down.

“It is all nominal,” Ivy said, but the last word was drowned out by a digital voice making an announcement over the arklet’s rudimentary PA system: “Bolo Coupling Operation entering its terminal phase. Prepare for acceleration.” And then in classic NASA style it counted down: “Five, four, three, two, one, grapple initiated.”

At “one” the test pattern on the screen disappeared in shadow, for it was too close now for the camera to even see it. The Paws of Arklet 2 and Arklet 3 slapped together, like runners exchanging a high five as they passed each other going opposite ways. Strange whiny noises propagated down the arm into the hard shell of the arklet.

“Grappling achieved,” said the voice.

Dinah’s ears finally identified the whiny noise as the sound of cable unwinding from a spool. She felt a lurch in her stomach as the arklet did a half somersault, reversing its direction so that it was pointed back at its bolo partner.

As she knew, having studied this maneuver for weeks, the two arklets were now joined together by a cable. They had flown right past each other, but the tension in that cable had spun them around so that they were pointing toward each other again—she verified this with a glance out the window, which gave her a view of the nose of Arklet 3 slowly receding as it “backed away” from them. The spool of cable mounted next to its docking port was in motion, unwinding as the two craft gained distance from each other. In the exact center, the cables of Arklets 2 and 3 were clasped together by a coupling device that could be remotely disengaged whenever they made the decision to go their separate ways.

“Congratulations, Bolo One,” said the engineer down in Houston. “The first autonomously driven coupling of two spacecraft to
create a rotating system for production of Earth-normal simulated gravity.”

Earth swung past beneath the other half of Bolo One and Dinah felt the awareness of her own throat that would culminate, five minutes from now, in vomiting. The two arklets were already swinging slowly around each other, producing a small amount of simulated gravity—even less than what they experienced in the Banana. But the MAP system wasn’t satisfied with that. Once the two arklets were far enough apart not to take damage from each other’s thruster exhaust, the system initiated a longer burn that, in combination with the slow unreeling of the cables, put their inner ears through some disturbing changes. The sound of the cable reels changed as automatic brakes engaged to slow their unwinding and avoid a damaging jerk at the end. Then there was silence for a few moments, and then another thruster burn—longer, and directed laterally, to speed up the bolo’s rotational velocity.

“Holy shit” was the only thing that Dinah could say for the first minute or two.

They were experiencing one gee—Earth-normal gravity—for the first time in over a year.

Markus, who’d only been in orbit for a few days, sounded great. To judge from what they were hearing in their headsets, he had unstrapped from his pilot’s couch and was clambering all over Arklet 3 as if it were the Daubenhorn.

Ivy and Dinah couldn’t move for several minutes, and Dinah seriously entertained the possibility that she was dying.

“Can you pass out while you’re lying down?” she finally asked.

“Remain in your positions,” a voice from Houston was saying, dimly, distantly, as if shouting at them through a bullhorn from four hundred kilometers below. “It is a long fall to the bottom of that arklet.”

A long fall. Dinah had ceased to even think in terms of up and
down. The concept of falling had become meaningless to her. When you were in orbit, you were always falling. But you never hit anything. She risked turning her head to look at the grate “below,” and that was the trigger that forced her to reach for her barf bag.

Doob had known for a while that he was not the easiest guy to be related to. During his last ten weeks on Earth, however, he sometimes feared he was pushing his family’s patience beyond human limits with his lust for camping.

Until then, his idea of a satisfying outdoor experience had been to saunter out onto the terrace of a European hotel to smoke cigars and drink brandy. His duties as an astronomer sometimes called him to remote locations such as the summit of Mauna Kea, where he would dutifully go outside, freeze his ass off for a few minutes, remark on the awesomeness of the view and the clarity of the air, and then go back inside to sit behind a workstation and stare at images on a screen. Camping, and the outdoor life in general, simply hadn’t been a part of the culture of his family, which tended to look with favor on being under a sound roof, in a heated space, behind locked doors, with plenty of food baking and frying in a modern, fully appointed kitchen. He had always admired his colleagues in the life and earth sciences who could hit the road on short notice with a fully stocked backpack and live rugged adventuresome lives in exotic locales. But he had admired them from a distance.

His sojourn to Moses Lake with Henry had turned him into a late convert to the outdoor life, and left him with a considerable stock of state-of-the-art gear that he was strangely eager to use. The visit to Bhutan had also been a trigger. This had been preceded by a lengthy series of flights across the Pacific and a brief stay on an aircraft carrier:
cramped, crowded, artificial environments not unlike where he would be spending the remainder of his days. Then, just for a blessed few hours, he had climbed out of that chopper into the high, cold, piney air of Bhutan, and gone for a ramble in the king’s Land Rover, and hiked up a misty mountain that had struck him as being straight from a 1970s album cover. And he had done some introspection about the fact that he couldn’t even take such a lovely place at face value but only liken it to such pop culture references. A few hours later he had been back on the aircraft carrier with Dorji and Jigme and about a hundred other Arkers who had been collected in a similar manner from Myanmar, Bangladesh, Nepal, various provinces of India, Sri Lanka, and scattered island groups. He had been struck by the contrast between how centered, how natural, how autochthonous the Bhutanese youths had looked when he had first seen them on the side of the cliff in their home country, and how lost they appeared in the painted steel companionway of an aircraft carrier, mixed up with other South Asians in equally colorful garb, all equally alienated from their native soil, all looking for a place to stow their priceless cultural artifacts.

He had come home with the idea in his head that he needed to get a little bit of native soil on himself before getting shot up to a place where he would be every bit as lost and alienated as Dorji and Jigme had been aboard USS
George H. W. Bush
. Which seemed uncontroversial to him. But when he presented the plan to Tav over a cup of naval coffee in one of the aircraft carrier’s eateries, Tav demurred. “You are totally overromanticizing dirt.”

Tav liked to play the devil’s advocate. He and Doob had had many such conversations. Doob shrugged and said, “Let’s say you’re right. What’s the worst that could happen if I get some dirt on me while I still have access to dirt?”

“Tetanus?”

“Before they started sending me to places like this, they made sure I was up to date on my shots.”

“No, seriously, I just don’t buy it, Doob.”

“Buy what? What is it you think I’m trying to sell you?”

“You’re trying to sell me the idea that there is such a thing as a state of nature that humans were designed to live in. It is the ‘dirt is good’ hypothesis.”
