SWAN AND A CAT
Swan got off the Wegener feeling embarrassed and depressed by the horrid ideas of her youth, in this case the savanna-pampas Ascension—not to mention her own poaching in same, caught red-handed indeed, the smart-ass. But then it got even worse when their taxi unloaded them into a terrarium headed Jupiterward, and it turned out to be the Pleistocene, another of her youthful indiscretions, an ice age north with any number of spavined megafauna resurrected and clomping around in pathetic mutant versions of themselves. Giant short-faced bears, looking around in openmouthed confusion—also dire wolves, saber-toothed tigers, American cheetahs, mastodons, and woolly mammoths, most of them only semi-genuine revivals from ancient DNA, really synthetics, birthed from elephants or lions or Kodiak bears, and thus uneducated in the ways of their kind. It was sad. Swan cursed herself and went feral to get through the remaining week to Jupiter, and almost paid for it with her life; for one thing, it was painfully cold, and then one morning she woke up in a stupidly uncomfortable perch in a tree to find it shaking under the weight of a cat climbing it, a big cat, a who-knew-what—possibly just a mountain lion, maybe a snow leopard, it had such long fur—intent to get to her, and as it was no heavier than she was, it seemed like it could climb the tree high enough to make it happen. Maybe twelve meters to the ground, terrarium spinning at one g—for a second she cursed the long-ago shift away from Martian g in terraria, which at first had been the norm—then fear drove all thought from her head. Get out of the nest. Get higher than a cat your own weight can get: obviously a problem. She pulled herself up onto the branch over her, which pronged up much more vertically than her sleeping branch. The cat eyed her calmly, not moving yet. Topaz eyes in brindled long white fur; upper lip drawn back, teeth white and hungry. No malice in it. Up the vertical branch, feet deep in forks, painful twists to free herself, up and up. Swaying now in the canopy, all the branches around her equally thin and flexible. Some kind of oak. If she kicked it on the snout when it attacked, possibly it would miss and fall. Foreclaws would latch on to her; her kick would have to twist away—maybe up. She tried to get higher, couldn’t.
She was on the Pleistocene. She carried a stun gun.
But she had left it in the nest. “Shit.”
The cat began to shift onto Swan’s branch. Quite a weight to sway it that much.
“Pauline, any suggestions here?”
“Scare it,” Pauline said. “Adrenalate fully, then do something bizarre.”
Swan twisted and let go, fell feetfirst into the face of the cat, screaming as loud as she could. When her feet hit something else, she clasped branches to her and felt something smash into her ribs. Air knocked out of her, no more scream. She scrabbled with her feet for some purchase, found none, looked down. The cat was on the ground, looking up at her. Swan screamed again, felt the stab of a cracked rib. She changed to a raging shout, cursing the cat foully. Kill it like Archilochus. Grating, painful snarl of a voice, bitter shrieking that hurt her throat and screeched unbearably in her own ears, the sound making her aware she had lost it. The cat heaved a heavy sigh and padded away.
She climbed back to her nest and retrieved the stun gun. Getting down out of the tree hurt like hell.
She avoided Wahram completely after that, and by the time they were dropped off on Callisto, she had become a little fond of that stab in her side. It made her feel better; it was an expression of her grief, her anger. The moment of dread involved was not forgotten, but digested into something else, some kind of triumph. She had almost been eaten for breakfast! She had been a fool and survived yet again—how often it had happened. Surely it was a fate. Surely it would keep on happening.
“This is the most basic of false syllogisms,” Pauline assured her when she spoke the thoughts aloud.
The Jovian moons were huge, with Jupiter itself a gargantuan oil painting of overelaborate genius, viscous blobs swirling around from one gorgeous paisley orangerie to the next; every border between the bands was a fantasia beyond compare. Swan loved the sight of it, and the city from which she viewed it wasn’t bad either: the Fourth Ring of Valhalla, built on the eponymous rim of the great multi-ringed crater. Valhalla had six rings, splashed into the side of Callisto like concentric waves on a pond after a rock is thrown in. The city was located on the top of the fourth ring, extending all the way around; now cities were beginning on the tops of the third and fifth rings as well. It was said that they would eventually tent the entirety of Valhalla and, after that, maybe all the rest of Callisto; and it was a big world. There were even those arguing it could be properly terraformed, despite the lack of a starter atmosphere.
It was one big world of four, in fact, because all the Galilean moons were gigantic. But there was some kind of a curse on them, it seemed to Swan; one of them was almost useless, another contested. Io orbited so far within Jupiter’s ferocious radiation belts that it was never going to be occupied at all except by a few small hardened scientific stations. Europa, a big beautiful ice moon, had a great depth of ice for people to delve into to escape the Jovian radiation, strong even there: wondrous ice palaces, with giant Jupiter always gnarling overhead—or everyone had thought at first. But it hadn’t happened, because there had proved to be aliens living in the ocean below, a complete ecology of algae, chemotrophs, lithotrophs, methanogens, scrapers, suckers, fans, scavengers, and detrivores, all swimming or crawling or holding on or burrowing in; and they created a problem. Some thought they had already contaminated this ocean by their exploratory intrusion into it, because examining it with a drill had been the Lake Vostok problem writ large. But they had done their best to sterilize the probes, and then, having discovered and sampled the full ecology, they had sealed off the hole, and now sat on the surface in scientific stations, culturing and studying their sample populations and pondering whether they should stay or go, and if they stayed, what kind of presence they should have. Possibly the proposed ice palaces would be perfectly fine, with the life below completely sequestered by the ten kilometers of glaciosphere that lay between the moon’s surface and its ocean. On the other hand, life being life, spermatozoically wriggling into every place it could reach, contamination might almost certainly be assumed to follow any occupation of the moon. And yet, given that these creatures appeared to be cousins of theirs anyway, long separated by meteor voyage—and now already recontaminated by a visit—would living above them and continuing to be a minor contaminant clearly be such a bad thing? When there were already people out there swallowing the alien microscopic life, and shooting it into their veins? And w
hen life had been bouncing around the solar system and interacting with its cousins all along? These were open questions, interesting and vivid to the Europans and the other Jovians, less so to the rest of the system. Swan remained somewhat interested from her design days, and she approved their recent decision to go ahead and settle Europa, only perching unobtrusively on top of the internal indigenous aquaria.
Now she spent her time walking the High Road that ran all the way round the Fourth Circle of Valhalla, waiting for their flight to Io. She was still avoiding Wahram, who watched her these days with a look of alarmed concern that she could not stand. Jupiter overhead was its usual lurid magnificence. Possibly the Jovians were right to be so self-absorbed; they had a whole little solar system here, full of different things. Between the rings of the crater, the surface of Callisto was a vast knobbly white plain, and Jupiter and the three other moons were up there performing their dance. It was a gorgeous space.
But they were here to see Wang, so soon she grew impatient for the Io shuttle, and tired of the view overhead. Jove squiggling its buffooneries over and over—it was not art but chemistry, mere fractal repetition. The saving grace was that they had recently lit great gas lamps in the upper Jovian atmosphere, to better illuminate the towns located on the Galileans’ Jovian sides. One could see how these painfully brilliant diamond points were distorting Jupiter’s cloud tops, adding new swirls and eddies; that made it art, the whole thing a kind of mad goldsworthy.
Finally the time came for the shuttle to Io.
Swan said, “Pauline, are you going to be all right down there?”
“I will be if you are. You definitely need to stay inside the Faraday cage there to stay safe. The Jovians will no doubt tell you that.”
And during the trip they did, at great length. In a box inside a box, like Russian dolls: they were so proud. Down then to Io, shedding a furious aurora behind their spacecraft, a blaze of transparent blue and green electric banners and flares arcing away as they flew.
IO
Io, the innermost moon of Jupiter, as big as Luna. The yellow slag world, awesome upchucking of a moon’s guts, regurgitation over and over until everything more volatile than sulfur has long since burned off. Sulfur, sulfur everywhere, and nary a place to stand. Four hundred live volcanoes bursting through the slag like angry boils, geysering sulfur dioxide hundreds of kilometers into the air. A moon with an interior hotter than Earth’s—and try putting your hand in front of the steam coming out of the volcanic vent on Néa Kaméni, in the caldera of Santorini, to feel just how hot Earth is; it looks like the steam on your stove top, but you will quickly find it is three times hotter. Even though you snatch your hand away instantly, your skin will blister. And Io’s interior is thirty times hotter than that.
It looks it. A hellworld, flexed hugely in the immense tidal pull between Jupiter and Europa, almost torn apart. That’s gravity at work. Then also Jupiter’s radiation field is so vast and so strong that Io sizzles inside it; even Deinococcus radiodurans perishes in it. Nothing lives on Io.
Except humans, and the little suite of biota they carry everywhere they go. For it is possible to find islands of hard rock in the highlands of the enormous volcanoes, and bore into that rock, and hide a little station. A cube to hold Wang’s qube. Everything there must be triply protected, first by physical walls, then by a magnetic field strong enough to counteract Jupiter’s radiation; but this field itself would be enough to kill, so inside that field a Faraday cage is necessary, to protect you from your protection.
Descend in a blue magnetic aurora, a fire of electrons. Below, the moon spreads from a ball to a plain to a tumultuous mountainscape of overlapping volcanoes, the bulky cones hard to spot in all the overlapping swaths of yellow on tan on white on black on brick on bronze, swaths of every burnt color, but most of all, yellow. Here and there scattered rings of black or red or white reveal active vents, pouring out the guts of the interior in irregular circles around the vents; but most of the patches are much less regular, and taken altogether, the surface is a jumble that cannot be resolved by the eye into a topography. It is what it looks like, a molten world, a world on fire. The names humans have applied are redundant. Fire gods, thunder gods, lightning and volcano gods, every combustible deity, from Agni the Hindu god of fire to Volund the German blacksmith of the gods: all these names attempt to humanize the moon, but fail. Io is not a human place. The hard crust on its surface, cooled only by contact with the chill vacuum of space, is so thin that in many places it would not support a standing person. Some early explorers found this out the hard way: walking too far away from their lander, they plunged through the sulfurous ground into red-hot lava and disappeared.
We think that because we live on cooler planets and moons, we live on safer ground than that. But it is not so.
SWAN AND WANG
The station on Io holding Wang’s qube and its support team was located high on the flank of Ra Patera, one of the biggest mountains in the solar system. As the ferry descended, the tilt of Ra’s broad apron came to seem barely off the horizontal. The ferry dropped into a gap in a concrete pad, and a roof then closed over them; from then on they were mostly underground. Everything they could see of the moon on the station’s various viewscreens, and through the little windows in the station’s little conning tower, was part of the apron of Ra.
There were several people in the station’s bridge, up in the conning tower. None of them looked up at Swan and Wahram, nor at Wang when he came in.
Wang Wei turned out to be a round person with an innocuous manner. A real principal investigator, as Mqaret would have said: one of the system’s foremost experts on qubes. Sometimes such individuals were sovereign to quite remarkable little Ruritanias. Swan wondered if Alex had been right in her notion that the solar system’s balkanization was a deliberate but unconscious human reaction to qubes, some kind of resistance to their incipient power.
Wang greeted Swan and Wahram, and with a quick “Ah, thank you,” took the envelope from Alex that Swan offered to him. It appeared he had already known about it. He read the letter in it, then plugged the tab that fell from it into the nearest desk. He stared at the desk console for a long time, reading carefully, using a forefinger to keep his place.
“So sorry to lose Alex,” he said to Swan finally. “Condolences from the heart. She was the hub of our little wheel, and now we spin off like broken spokes.”
Surprised at this, Swan said, “She told me in her note to me that I should come to you. The messages were left for me in her study. A kind of contingency plan, I guess. And part of it was this envelope for you.”
“Yes. She told me she might do this. And you also loaded a tab into your internal qube, Alex suggests in her note here.”
“That’s right. But my qube won’t tell me about it.”
“That was no doubt Alex’s instruction. The data are specialized. What you have is a kind of backup,” Wang explained apologetically.
Swan glared at Wang, and then Wahram, and saw that they were in cahoots, like Wahram and Genette back on Mercury. “Tell me what’s going on,” she demanded. “You two were working with Alex on something.”
The two of them hesitated, and then Wang said, “Yes. For many years. Alex was the hub, as I said. We were working with her.”
“But she didn’t like being in the cloud,” Swan said, gesturing around her at the station. “She kept things in her head, right? But you work with qubes, isn’t that right? Wang’s qube, Wang’s algorithm?”
“Yes,” Wang said.
Wahram said, “To stay off the record, Alex had to stay clear of qubes. And for that she needed a qube’s help. That’s just the way it is now, and she knew that.”
Wang nodded. “So she chose me. I can’t say why. Possibly she thought I have more contact than I really do with what she used to call the league of unaffiliated worlds. I do have a network of contacts like that, but it’s not comprehensive. No one has an accurate description of the system as it e
xists now.”
“Is that what Alex wanted?” Swan asked.
Wahram shook his head. “She knew the system as well as anyone could. Wang knows the unaffiliateds, but more importantly, to my mind, his qube is sequestered here. Its contact with the rest of the system is controlled by Wang. Alex liked that, because she was trying to shift all her dealings over to direct human communication.”
“But she left these messages,” Swan said. “For if she couldn’t talk. So she wanted us to talk. For you two to talk to me.”
“Evidently.”
“So tell me what you’re up to!”
The two men glanced at each other. For a long time they stared at the floor.
Then Wang looked her in the eye, which caught Swan by surprise. His gaze was intense. “No one knows exactly how to deal with this situation, because it has to do with qubes, and you have a qube embedded in you. So Alex would not tell you about this part of things, and I don’t want to either. Now that Alex’s list of contacts is safely here, we who were working with her can try to proceed with her plans.”
Swan said, “So you have information from Alex, and my qube has information from Alex, but I can’t have any information from Alex.”
Wang looked at Wahram. Wahram’s broad face looked as if pins were being stuck into him somewhere. His pop-eyed stare, Wang’s basilisk intensity: they stood there looking at her. They didn’t know what to say to her. They weren’t going to tell her anything.
