The Ouroborous team in Sheffield occupied one floor of Praxis’s downtown skyscraper. The company had gotten its start excavating the old town, before the ruins had been so unceremoniously shoved over the side. A man named Zafir headed the fallen cable salvage project, and he and Adrienne accompanied Art to the train station, where they got on a local train and took a short ride around to the east rim, to a line of suburb tents. One of the tents was the Ouroborous storage facility, and just outside it, among many other vehicles, was a truly gigantic mobile processing factory, called the Beast. The Beast made a SuperRathje look like a compact car— it was a building rather than a vehicle, and almost entirely robotic. Another Beast was already out processing the cable in west Tharsis, and Art was slated to go out and make an on-site inspection of it. So Zafir and a couple of technicians showed him around the inside of the training vehicle, ending up in a wide compartment on the top floor, where there were living quarters for any humans who might be visiting.
Zafir was enthusiastic about what the Beast out on west Tharsis had found. “Of course just recovering the carbon filament and the diamond gel helixes gives us a basic income stream,” he said. “And we are doing well with some brecciated exotics metamorphosed in the final hemisphere of the fall. But what you’ll be interested in are the buckyballs.” Zafir was an expert in these little carbon geodesic spheres called buckminsterfullerenes, and he waxed enthusiastic: “Temperatures and pressures in the west Tharsis zone of the fall turned out to be similar to those used in the arc-reactor-synthesis method of making fullerenes, and so there’s a hundred-kilometer stretch out there where the carbon on the bottom side of the cable consists almost entirely of buckyballs. Mostly sixties, but also some thirties, and a variety of superbuckies.” And some of the superbuckies had formed with atoms of other elements trapped inside their carbon cages. These “full fullerenes” were useful in composite manufacturing, but very expensive to make in the lab because of the high amounts of energy required. So they were a nice find. “It’s sorting out the various superbuckies where your ion chromatography will come in.”
“So I understand,” Art said. He had done work with ion chromatography during analyses in Georgia, and this was his ostensible reason for being sent into the outback. So over the next few days Zafir and some Beast technicians trained Art in dealing with the Beast, and after these sessions they had dinner together at a small restaurant in the suburb tent on the east rim. After sunset they had a great view of Sheffield, some thirty kilometers around the curve of the rim, glowing in the twilight like a lamp perched on the black abyss.
As they ate and drank, the conversation seldom turned to the matter of Art’s project, and, considering it, Art decided that this was probably a deliberate courtesy on his colleagues’ part. The Beast was fully self-operating, and though there were some problems to be solved in sorting out the recently discovered full fullerenes, there must have been local ion chromatographers who could have done the job. So there was no obvious reason why Praxis should have sent Art up from Earth to do it, and there had to be something more to his story. And so the group avoided the topic, saving Art the embarrassment of lies, or awkward shrugs, or an explicit appeal to confidentiality.
Art would have been uncomfortable with any of these dodges, so he appreciated their tact. But it put a certain distance in their conversations. And he seldom saw the other Praxis newcomers, outside of orientation meetings; and he didn’t know anyone else in town, or elsewhere on the planet. So he was a little lonely, and the days passed in an increasing sense of uneasiness, even oppression. He kept the drapes closed on his window view, and ate in restaurants away from the rim. It began to feel a bit too much like the weeks on the Ganesh, which he now understood to have been a miserable time. Sometimes he had to fend off the feeling that it had been a mistake to come.
And so after their last orientation lecture, at a reception luncheon in the Praxis building, he drank more than was his custom, and took a few inhalations from a tall canister of nitrous oxide. Inhalation of recreational drugs was a local custom, fairly big among Martian construction workers, he had been told, and there were even little canisters of various gases for sale from dispensers in some public men’s rooms. Certainly the nitrous added a certain extra bubbly quality to the champagne; it was a nice combination, like peanuts and beer, or ice cream and apple pie.
Afterward he walked down the streets of Sheffield bouncing erratically, feeling the nitrous champagne as a kind of antigravitational effect, which, added to the Martian baseline, made him feel altogether too light. Technically he weighed about forty kilos, but as he walked along it felt more like five. Very strange, even unpleasant. Like walking on buttered glass.
