Kim was going on a jog. On the Earth Ring of the station, his blood pumped too fast. He was getting deconditioned on the Luna Ring and had been advised by the doc heuristic to get more exercise at 1G. He felt that there just wasn't anything else quite like jogging. As he left the windowed portion of the ring, he grew mildly annoyed with the peculiar design of the station. They had built the two rings of Clarke Point resembling two links of a chain, interlocking inside each other. This meant that as each ring rotated, each section entered and exited the windowed sections periodically, as the rest of the interior was mostly solid. He had heard that they did this because it saved a lot of money on hull area, but he didn't quite believe that. It just seemed bad, at least until you saw it from outside.
As the station's only veterinarian, Kim was usually quite busy. The Earth-Luna L1 lagrange station was the main interchange between the two worlds, and while the worlds turned, people never stopped loving their pets. He cared for cats, dogs, rodents (including the prodigious population of laboratory test animals), birds, anything that crossed the station. He had made friends with more than his fair share of wayward higher apes, one or two of whom were there to conduct research themselves. He had to inspect and validate every animal, often consulting a constantly-expanding index of genetic modifications and their variants. This had the curious side-effect that he had personally met and looked over nearly ever non-human animal on the moon, as he had been hired on when the station opened.
His position had proven strangely impervious to the many waves of automation heuristics that had claimed vast territories of employment during his rather modest lifespan. While human biology had been chipped away at, scanned, processed, and finally understood by computers with far greater penetrating objectivity and insight than had ever been hoped for in the past, the comparative wild west of animal physiology hadn't yet been put to the machines. After all, there were many more species of animal. Hell, the way he did his job was half-automated by now anyway. But humans are nothing if not emotional, and pet owners felt better seeing a person inspecting their beloved creature, and he was the only vet for hundreds of thousands of miles.
The station had proven pivotal these last few years. The moon settlements had flourished with their mix of frontier mining, shipping, and extremely advanced industrial manufacturing. As settlement and exploitation of the asteroid belt had begun in earnest, it was far easier to deposit raw material on Luna than descending all the way into Earth's gravity well and having to climb back out. Thus, the huge moon had become an epicenter of industry, with most manufacturing applications using material from the asteroids occurring there and getting shipped back to Earth in specialty high-G freighters.
Clarke Point had been built 7 (Earth) years ago to serve as combination port-of-entry, layover, shipping center, and crossover point for the Earth-Luna system. Its designers knew it would be an icon for the Solar Age and had decided to make a justifiable decision to shape the station as an oloid, a previously-rare shape created, conveniently, out of a hull thrown between two interlocking rings. The shape was not only highly provocative to gaze upon up close, it really did save money on hull shielding compared to many other non-spherical proposals at the time. While most of its many permanent residents often complained about the window situation, they also often agreed that it was good to live inside of a thing that would grace postcards for many decades to come. The tourists and the passers-through always loved it.
Kim felt a vibration at the back of his ear and cursed under his breath. He would have to catch a train back to the moon ring and cut his job short. The demands of biology not yet tamed, he turned.
