Science Fiction: The Best of the Year, 2008 Edition

by Rich Horton

  About dawn he sat up, drank more water and swallowed some food, and skied easily to the top of the dune crest, where Baggins had just managed to carry Léoa after toiling in that slow spiral around the bowl all night. The monitor said she was fast asleep, and Thorby thought that was the best possible thing. Through most of the morning and into the afternoon, he skied along the newly reorganized dune crests, working a little ahead of Baggins and then sitting down to wait for it to catch up, listening to the slow spitting of sand against his suit, and watching the low red dust clouds gather and darken, with only his thoughts for company.

  * * * *

  When Léoa finally awoke, she said, “I'm hungry.” It startled Thorby; he was about sixty meters ahead, using his two remaining stalkers to shoot the dunes through the red dust that was still settling.

  “Be right there,” he said, and skied back, the stalkers hopping after him. Her mouth, throat, and digestive system were basically okay, according to the medical sensors, though they wanted her to eat mostly clear broth till she could be looked at properly in a hospital. This time she chose chicken broth, and he hooked it up so she could sip it. All the diagnostics from the rescue frame said she was more or less normal, and as far as he could tell the broken leg and spine were the major damage.

  After a while she said, “If I call out my stalkers, will you tell the story about the bicycle ride around the comet, and all those things about becoming famous?”

  “Sure,” he said, “if it will make the time pass better for you. But I warn you it's very dull.”

  So he sketched out the basics, in his best “I am being interviewed” voice, as the red dusty sky grew darker. When he was fourteen he had been sent to live with his grandmother because his mother had a promising career going as an actress and his being visibly a teenager would have spoiled her image as a sex object for teenage boys. His grandmother had been part of the earliest team for the first Great Bloom projects, so he had found himself dispatched to Boreas with her, forty-five AU from the sun—so far out that the sun was just a bright star. He had been bored and unhappy, spending most of his time playing games in VR and bored even there because he was so far from the rest of the solar system that radio signals from anywhere else, even Triton Station, took most of a day for a round trip.

  “So on the day of the first fire-off—”

  “Fire-off? You mean the atom bomb?”

  “Well, sort of atom bomb. Laser initiated fusion explosive, but nobody wanted to call a bomb LIFE. Yeah, the thing that started Boreas falling down into the lower solar system.” He skied back to look at her life support indicators; they were all green so as far as he knew, she was fine. “On that day, Grandma insisted that I suit up, which I didn't want to do, and go outside with her, which I really didn't want to do, to sit and watch the sky—the gadget was going to be blowing off over the horizon. They put it in an ellipsoidal superreflecting balloon, at one focus, and then put the other focus of the ellipsoidal at the focus of a great big parabolic parasol—”

  “None of this means a thing to me.”

  “They had these really thin plastic reflectors to organize it into a beam about a kilometer across, so all that light, X-rays, heat, everything pretty much hit one square kilometer and blew off a lot of ice and snow in one direction.”

  “That's better. So, you got to see one big explosion and you liked it so much you decided to see them for the rest of your life?”

  “My helmet's opaqued—did you want a reaction shot to that?”

  “I'll make one up,” she said. “Or use stock. I'm not that purist anymore. Anyway, I've heard you mention it two or three times, so what was Cookie Crumb Hill?”

  “Home. It was where the base was. Basically a pile of sand cemented together with water ice, it was the boat for the base.”

  “The boat?”

  “It floated on what was around it, and if anything had gone wrong it would have ejected as a whole, so we thought of it as a boat. But we called it Cookie Crumb Hill because it was a pile of meter-or-bigger ice clods. The stuff in the core was mostly silica, so the robots spun that into glass fibers, stirred that into melted water, and added enough vacuum beads to make it float on the frost, because otherwise anything we built would have been under twenty-five kilometers of frost.”

  A virgin Kuiper Belt Object begins as a bit of dust accumulating frost. It accretes water, ammonia, methane, hydrogen sulfide, all the abundant things in the universe, a molecule at a time. Every so often it adds more dust, and as it grows bigger and bigger, the dust sinks through the loose vacuum frost to the center. At Kuiper Belt velocities, hardly anything ever hits hard enough to cause vaporization, and anyway it's too cold for anything to stay vapor for long. So over billions of years, the frost at the center packs slowly around the dust, and all of it sinks and compacts into a kind of sandy glacier. Frost on top of that sandy glacier packs in to form “fizzy glacier"—water ice mixed with methane and carbon dioxide ice. And always the surface at a few kelvins, where the slight mass and the low gravity are not enough to compact the crystalline structures, grows as thick frost; at the bottom of twenty-five kilometers of frost, on a world as small and light as Boreas, the total pressure was less than the air pressure of Mars. Time alone made Boreas large and its center hard.

  “So before people got there,” Léoa said, “you could say it was one big snowflake. Fractally elaborated fine structures of ice crystals, organized around a dust center—just that it was over seven hundred kilometers across.”

  “Small dust center, big compacted ice center,” he said. “More like a snowball with a lot of frost on it. But I guess you're right, in a sense. So we called it Cookie Crumb Hill because with the fiber and beads in them, the ice boulders looked sort of like cookie crumbs, and we built it up in a big flat pyramid with sort of a keel underneath to keep it from turning over, so it was also a boat on a fluffy snowball, or if you would rather call it that, a snowflake ... Anyway, I was a complete jerk as a teenage boy.”

  “I had twin teenage boys a couple decades ago,” Léoa said, “and I might have the reversal and have more babies, but only if I can drown them or mail them away at age twelve.”

  Thorby skied alongside Baggins to check her indicators; she was farther into the green range, probably feeling better, and that was good.

  “Well,” he said, “I was unusually unpleasant even for a teenager, at least until the bicycle ride. Though being bad wasn't why Mom got rid of me; more like the opposite, actually.” It came out more bitter than he had expected it to; he sometimes thought the only time he'd really been emotionally alive was between the ages of thirteen and eighteen, because everything after seemed so gray by comparison. “Anyway, I sat up there with Gran, and then there was a great light in the sky over the horizon, and about ten minutes of there being an atmosphere—I felt wind on my suit and for just a moment there was a sky instead of stars—and then, poof-click, all this new spiky frost forming everywhere. That was when the idea started, that it would be wonderful to be outside for a long period of time, especially if I could control what I did and how I spent my time.

  “So for physics class, I figured out the gadget and had the fabricators make it. That kilometer-across loop of spinning superconductor that was basically a big flywheel I could spin up to orbital velocity by doing shifts pedaling the treadmill, so over about a month I got in shape. Bicycle that I could ride around the inside of the loop as a maglev, picking up speed and momentum for the loop. That was trivial stuff, any lab could build that now, and our local robots didn't have much to do once the base was done. So I built my loop and my bicycle, or rather the robots did, and pedaled the loop for a few hours a day. In a frictionless very low g environment, the momentum adds up, and eventually that loop was moving at close to six hundred kilometers per hour, more than orbital velocity. With controllable superconduction on my bike tires, I could gradually increase the coupling, so I didn't get yanked off the bike when I first got on, and just ride my relative speed
up high enough before getting off the loop and into orbit.

  “Then I just needed the right timing, enough air, food, and water, and a way to come down when I got bored. The timing was done by a computer, so that I pulled out of the loop right at the top, while I was riding parallel to the ground, and I just had a one time program to do that, it took over and steered when it needed to, since my launch window was about three meters long and at that speed, that went by in about a sixtieth of a second. A recycling suit took care of the air and water. The food was in the big container I was towing. And the container, when it was empty, could be given a hard shove, and dragged through the frost below, as an anchor to get down to about a hundred kilometers per hour, when I'd inflate the immense balloon tires around the superconducting rims, and skim along the frost back to Cookie Crumb Hill.

  “I just put the camera on the handlebars, facing backward, so that I'd have a record when I turned the project in for a grade, and then since I had to take a documentation class the next term, I used the footage. I had no idea people would get all excited about the image of me on that bicycle, food hamper towing behind me, with all that Boreas in the background.”

  “You looked like you were riding over it like a witch on a broomstick,” she reminded him, “because the producer that bought it made it consistent that your head was upright in the picture, and the way a body in a gravitational field positions itself, the bike ended up toward Boreas.”

  “'It matters not what happened or how it was shot, the editor will decide what it was,'” he quoted, and skied forward a bit to stretch his tired legs and enjoy some exercise in the little daylight there was. Probably it would be another day or two before there was a rescue.

  When he came back, and found her still rolling along on the rescue frame (which, to his eyes, kept looking more and more like a cross) on top of Baggins, she was still awake and wanted some more soup, so he set that up for her. “This probably is a good sign for your quick recovery,” he pointed out. “The rescue people say they'll pick us up sometime tomorrow, so we could just camp here, but if we cover another fifteen kilometers tonight and tomorrow morning, we can officially say we got out of the Sand Sea all by ourselves. Which is more comfortable for you, stationary or rolling?”

  “With my eyes closed I can't tell the difference; your porter is pretty good at carrying a delicate object. I can't get out of the suit anyway, so you're the one who setting up a shelter might make a difference to. So let's keep moving till you want to do that, and then move again in the morning when you're ready.”

  “That'll work.” It was almost dark now, and though he could steer and avoid hazards all right by light amps and infrared, and find his way by the same navigation system that Baggins used, it was a sort of scary way to proceed and he didn't like the idea of risking something going wrong with Léoa. “I guess I'll make camp here.”

  The shelter took a few minutes to inflate, and then Baggins carried her inside and set her on cargo supports, so he could at least remove her helmet and let her breathe air that came from the shelter's generator, and eat a little bit of food she could chew, mostly just pastelike stuff from tubes that the medical advisor said she could have. When he had made her comfortable, and eaten a sitting-up meal himself, he stretched out on a pad himself, naked but feeling much better after a sponge bath. He told the shelter to make it dark, and didn't worry about setting an alarm time.

  “Thorby?”

  “Need something?”

  “Just an answer to the last part of the question. So how did orbiting Boreas for a month, living on suit food and watching the frost form on the surface as a lot of the evaporated stuff snowed back in—I mean, basically, it was a novelty act, you were just orbiting a snowball on a bicycle—how did that launch everything for you?”

  “My big secret is it didn't,” he said, not sure whether telling her could change anything. “For most of the ride I played VR games on my visor and caught up on sleep and writing to pen pals. I shot less than five hours of camera work across that whole month. Sure, orbiting a kilometer up from a KBO's surface is interesting for a few minutes at a time. The frost spires and the big lacy ground patterns can be kind of pretty, but you know, a teenage boy doesn't appreciate much that his glands don't react to. I finally decided that I could stand company again, tossed the food container downward on the stretch-winch, slowed down to about a forty kilometers per hour across a few hundred kilometers of frost—the rooster tail from that was actually the best visual of the trip, I thought, with a line down from my bicycle to the surface, and then snow spraying everywhere from the end of the line—came in, got a shower, put it together, and forgot about it till it made me famous. At which point it also made it famous that Mom had a teenage son, which was badly blowing the ingénue image, so she filed repudiation papers with Image Control, and I've never seen or heard from her since. The biggest thing I learned, I'm afraid, was that I like having a lot of time to myself, and people bug me.”

  “What about big explosions?”

  “I like them, I always did. And I liked watching frost re-form after moving Boreas around, and I just like to see stuff change. I know you're looking for something deeper, but you know, that's about it. Things end, new things form, new things end, newer things form. I just like to be there.”

  She didn't ask again, and he heard her breathing grow slower and deeper. He thought about the visuals he had, and about a couple things he wanted to make sure to do when Boreas did its South Pole pass, and was asleep almost at once in the perfect dark and silence of the Martian wilderness.

  * * * *

  “All right,” she said, “I'll tell you as much as I can, since you are going to ask.” He was sitting beside her reconstructor tank in the hospital. “That's why you came back, right, to ask why I would do such a thing?”

  “I don't really know if that is why I came here,” he said. “I wanted to see how you were, I had some days before I go down to the South Pole, and since I put some effort into having you be alive, I guess I just wanted to see the results. I'm not planning to work with you again, so I don't really have to know why you wrecked my stalkers just before some key shots, only that you might, to avoid you.”

  “I suppose after what I did there's no question of your ever liking me.”

  “I'm a loner, I don't like people much anyway.”

  “Some people might guess that's why you like BEREs. The people who used to love the place the way it was are gone, and the people who are going to love the place it will be aren't there yet. For just that instant it's just you and the universe, eh?”

  She must be recording this. It was the sort of thing you asked an interviewee, and her audience in particular would just gobble this down. Perhaps he should spoil it, and pay her back for having spoiled the first Boreas-pass for him?

  Except she hadn't spoiled it. He'd be getting plenty of shots of the later passes and anyway good old Stalker Two had gotten most of what he wanted, including the fiery column from the surprise impact. And even if she hadn't done that, they'd have missed most of it through having to grab the stalkers and flee for their lives.

  So it mattered, but not a lot; he just didn't want her around when he was shooting anything important. As for rescuing Léoa, well, what else could a guy do? That didn't create a bond for him and he couldn't imagine why it might for her. It was just something he did because it was something people did at a time like that.

  “You're looking like you've never had that thought before,” Léoa said.

  He thought, what thought? and said, “I guess, yeah.”

  “You see? We're not so different from each other. You like to see the moment when something beautiful changes into something new. And you don't care that things get all smashed when that happens. In fact you enjoy the smash, the beautiful death of something natural and beautiful, and the birth of a beautiful human achievement.”

  He thought, what? and was afraid he would have to say something.

  But by now she wa
s rolling. “Thorby, that was what I wanted to capture. Thorby, Lonely Thorby, Thorby the Last Mountain Man, finds out he can be betrayed by people he thought were his friends. The change of your expression as it happened. The way your body recoiled. The whole—my idea is, I'm going to overlay all that and interact it, touchlinked back and forth everywhere, with the changes on Mars, show Mars becoming a new living world artificially, and show Thorby engaging and rejoining the human race, artificially, in a dialogue. Show you becoming someone who can hate and maybe even eventually love. Someone who can see that the rest of us are here. The way Mars can learn to respond to life on its surface, in a way that it hasn't in the three centuries we've been there.”

  At least he knew about this. People had been trying to change Thorby his whole life. He'd never been any good at being changed. “So you wanted to get the moment when I changed, for your docu?” It was a stupid question, she'd told him, but interviewers have to ask stupid questions now and then, if they want to get decent quotes, and habits die harder than passions.

  “That's it, that's it exactly. Exactly. I'm giving up on the whole purist-realist movement. You can have it to yourself. It not only isn't making me famous, it's not even keeping you famous. I've got an idea for a different kind of docu altogether, one where the human change in celebs, and the Blooming change in the solar system, echo and describe each other in sort of a dialogue. If you're interested, and I bet you're not, I've recorded sort of a manifesto of the new movement. I've put it out already. I told them what I did to you and why and showed your face, which wasn't as expressive as it could be, by the way. Too bad you never want to do another take. And even though in the manifesto I explain it will be at least twenty years before my next docu, instead of the usual five or six, because I want to get at least that much of the Mars changes into it, the manifesto is still getting the most attention I've ever gotten. I've got a bigger audience than ever, even pulling in some of my backlist. I'm going to have an impact.”
