When you expect to live another two hundred years, you behave differently than when you expect to live only twenty.
This they proved almost immediately. John spent the winter there at Acheron, on the edge of the CO2 fog cap that still descended over the north pole every winter, studying areobotany with Marina Tokareva and her lab group. He did this on Sax’s instruction, and because he felt in no hurry to leave. Sax seemed to have forgotten about the search to find out who the saboteurs were, which made John a little suspicious; in his spare time he still made efforts through Pauline, concentrating on the areas he had been working on before Acheron; travel records mostly, and then employment records of all the people that had traveled to the areas where the sabotages had taken place. Presumably there were a lot of people involved, so individual travel records might not tell him much. But everyone on Mars had been sent there by an organization, and by checking which organizations had sent people to the relevant places, he hoped to get some indications. It was a messy business, and he had to rely on Pauline not only for statistics but advice, which was worrying.
The rest of the time he studied a branch of areobotany in which all the payoffs were at least decades away. Why not? He had the time, and might very well see the fruits of the work. So he watched Marina’s group design a new tree, studying with them and doing their lab work, washing glassware and the like. The tree was designed to serve as the canopy of a multi-layered forest which they hoped to grow on the dunes of Vastitas Borealis. It was based on a sequoia genome, but they wanted trees even bigger than sequoias, perhaps two hundred meters tall, with a trunk fifty meters in diameter at the base. Their bark would stay frozen most of the time, and their broad leaves, which would probably look as if they had tobacco leaf disease, were going to be able to absorb the baseline dose of UV radiation without damage to their purplish undersides. At first John thought the trees’ size was excessive, but Marina pointed out that they would be capable of taking in great quantities of carbon dioxide, fixing the carbon and transpiring the oxygen back into the air. And they were going to be quite a sight, or so they supposed; the actual shoots of the competing test prototypes were only ten meters tall, and it would be twenty years before the winners of the competition reached their mature heights. And right now all the prototypes still died in Mars jars; atmospheric conditions would have to change considerably before they would survive outdoors. Marina’s lab was getting ahead of the game.
But so was everyone else. This seemed to be a result of the treatment, it made sense on the face of it. Longer experiments. Longer (John groaned) investigations. Longer thoughts.
In many respects, however, nothing changed. John felt about the same as before, except it didn’t take omegendorph to get an occasional buzz humming through him, as if he had recently finished swimming a couple of kilometers, or cross-country skied for an afternoon, or, yes, taken a dose of omegendorph. Which now would have been carrying coals to Newcastle. Because things glowed. When he took the crest walk, the whole visible world glowed: stilled bulldozers, a crane like a gallows – he could watch anything for minutes on end. Maya left for Hellas, and it didn’t matter; their relations were back on the old rollercoaster ride, a lot of bickering and fits of temper on her part, but all that seemed unimportant, floating inside the glow, changing nothing in the way he felt toward her, or in the way she had, from time to time, turned on him that look of hers. He would see her in a few months, and talk to her on screen; meanwhile this was a separation he was not entirely unhappy to see.
It was a good winter. He learned a lot about areobotany and bioengineering, and in many of the evenings, after dinner, he would ask the Acheron people both individually and severally what they thought the eventual Martian society should be like, and how it should be run. At Acheron this usually led directly to considerations of ecology, and its deformed offshoot economics; these to them were much more critical than politics, or what Marina called “the supposed decision-making apparatus”. Marina and Vlad were particularly interesting on this topic, as they had worked out a system of equations for what they called “eco-economics", which always sounded to John like “echo economics.” He liked listening to them explain the equations, and he asked them a lot of questions, learning about concepts like carrying capacity, coexistence, counteradaptation, legitimacy mechanisms, ecologic efficiency. “That’s the only real measure of our contribution to the system,” Vlad would say. “If you burn our bodies in a microbomb calorimeter you’ll find we contain about six or seven kilocalories per gram of weight, and of course we take in a lot of calories to sustain that through our lives. Our output is harder to measure, because it’s not a matter of predators feeding on us, as in the classic efficiency equations – it’s more a
