But she could feel it. No doubt others did as well. Quiet conversations between couples; changes in dining room partners; quick glances, small smiles; hands touching shoulders or elbows in passing; oh yes, things were happening. It made for a kind of tension in the air, a tension that was only partly pleasant. Antarctic fears came back into play; and besides, there was only a small number of potential partners, which tended to give things a musical chairs kind of feeling.

And for Maya there were additional problems. She was even more wary than usual of Russian men, because in this case it would mean sleeping with the boss; she was suspicious of that, knowing how it had felt when she had done it herself. Besides, none of them… well, she was attracted to Arkady, but she did not like him; and he seemed uninterested. Yeli she knew from before, he was just a friend; Dmitri she didn’t care for; Vlad was older, Yuri not her type, Alex a follower of Arkady’s… on and on like that.

And as for the Americans, or the internationals; well, that was a different kind of problem. Cross cultures, who knew? So… she kept to herself. But she thought about it. And occasionally, while waking up in the morning, or finishing a workout, she floated on a wave of desire that left her washed up on the shore of bed or shower, feeling alone.

Thus late one morning, after a particularly harrowing problem run, which they had almost solved and then failed to solve, she ran into Frank Chalmers in the forest biome and returned his hello, and they walked for about ten meters into the woods, and stopped. She was in shorts and tank-top, barefoot, sweaty and flushed from the crazed simulation. He was in shorts and T-shirt, barefoot, sweaty and dusty from the farm. Suddenly he laughed his sharp laugh, and reached out to touch her upper arm with two fingertips. “You’re looking happy today.” With that darting smile.

The leaders of the two halves of the expedition. Equals. She lifted her hand to touch his, and that was all it took.

They left the trail and ducked into a tight thicket of pine. They stopped to kiss, and it had been long enough since the last time that it felt strange to her. Tripping over a root Frank laughed under his breath, that quick secretive laugh which gave Maya a shiver, almost of fear. They sat on pine needles, rolled together like students necking in the woods. She laughed; she had always liked the quick approach, the way she could just knock a man down when she wanted to.

And so they made love. For a time passion took her away. Afterwards she relaxed, enjoying the wash of afterglow. But then it got a bit awkward, somehow; she didn’t know what to say. There was something hidden still about him, as if he were hiding even when making love. And even worse, what she could sense behind his reserve was some kind of triumph, as if he had won something and she had lost. That Puritan streak in Americans, that sense that sex was wrong and something that men had to trick women into. She had closed up a little herself, annoyed at that hidden smirk on his face. Win and lose, what children.

And yet they were co-mayors, so to speak. So if it was put on a zero sum basis…

Well, they talked for a while in a jovial enough way, and even made love again before they left. But it wasn’t quite the same as the first time, she found herself distracted. So much in sex was beyond rational analysis. Maya always felt things about her partners that she could not analyze or even express; but she always either liked what she felt or didn’t, there was no doubt about that. And looking at Frank Chalmer’s face after the first time, she had been sure that something wasn’t right. It made her uneasy.

But she was amiable, affectionate; it would not do to be put off at such a moment, no one would forgive that. They got up and dressed and went back into Torus D, and ate dinner at the same table with some others, and that was when it made perfect sense to become more distant. But then in the days after their encounter, she was surprised and displeased to find herself putting him off a little bit, making excuses to avoid being alone with him. It was awkward, not what she had wanted at all. She would have preferred not to feel the way she did, and once or twice after that they went off alone again, and when he started things she made love with him again, wanting it to work, feeling that she must have made a mistake or been in a bad mood somehow. But it was always the same, there was always that little smirk of triumph, that I-got-you that she disliked so much, that moralistic Puritan double-standard dirtiness.

And so she avoided him even more, to keep from getting into the start situation; and quickly enough he caught the drift. One afternoon he asked to go for a walk in the biome, and she declined, claiming fatigue; and a staccato look of surprise passed over his face, and then it had closed up like a mask. She felt badly, because she couldn’t even explain it to herself.

To try to make up for such an unreasonable withdrawal, she was friendly and forthright with him after that, as long as it was a safe situation. And once or twice she suggested, indirectly, that for her their enounters had been only a matter of sealing a friendship, something she had done with others as well. All this had to be conveyed between words, however, and it was possible he misunderstood; it was hard to say. After that first jolt of comprehension, he only seemed puzzled. Once, when she left a group just before it broke up, she had seen him give her a sharp glance; after that, only distance and reserve. But he had never been really upset, and he never pressed the issue, or came to her to talk about it. But that was part of the problem, wasn’t it? He didn’t seem to want to talk to her about that kind of thing.

Well, perhaps he had affairs going with other women, with some of the Americans, it was hard to say. He really did keep to himself. But it was… awkward.

Maya resolved to abolish the knockover seduction, no matter the thrill she got from it. Hiroko was right; everything was different in a closed system. It was too bad for Frank (if he did care), because he had served as her education in this regard. In the end she resolved to make it up to him, by being a good friend. She worked so hard at doing this that once, almost a month later, she miscalculated and went a little too far, to the point where he thought she was seducing him again. They had been part of a group, up late talking, and she had sat next to him, and afterwards he had clearly gotten the wrong impression, and walked with her around Torus D to the bathrooms, talking in the charming and affable way he had at this stage of things. Maya was vexed with herself; she didn’t want to seem completely fickle, although at this point either way she went it would probably look that way. So she went along with him, just because it was easier, and because there was a part of her that wanted to make love. And so she did, upset with herself and resolved that this should be the last time, a sort of final gift that would hopefully make the whole incident a good memory for him. She found herself becoming more passionate than ever before, she really wanted to please him. And then, just before orgasm, she looked up at his face, and it was like looking in the windows of an empty house.

That was the last time.

?V. V for velocity, delta for change. In space, this is the measure of the change in velocity required to get from one place to another — thus, a measure of the energy required to do it.

Everything is moving already. But to get something from the (moving) surface of the Earth into orbit around it, requires a minimum?v of ten kilometers per second; to leave Earth’s orbit and fly to Mars requires a minimum?v of 3.6 kilometers per second; and to orbit Mars and land on it requires a?v of about one kilometer per second. The hardest part is leaving Earth behind, for that is by far the deepest gravity well involved. Climbing up that steep curve of spacetime takes tremendous force, shifting the direction of an enormous inertia.
