People were arguing again, there in the shallows of the lap pool. Ann, tall and angular, leaning down to snap something at Sax Russell, short and soft. As usual, he didn’t appear to be listening. She would hit him one day if he didn’t watch out. It was strange how the group was changing again, how the feel of it was changing. She could never get a fix on it; the real nature of the group was a thing apart, with a life of its own, somehow distinct from the characters of the individuals that constituted it. It must make Michel’s job as their shrink almost impossible. Not that one could tell with Michel; he was the quietest and most unobtrusive psychiatrist she had ever met. No doubt an asset, in this crowd of shrink-atheists. But she still thought it was odd he hadn’t come by to see her after the accident.
One evening she left the dining chambers and walked down to the tunnel they were digging from the vaulted chambers to the farm complex, and there at the tunnel’s end were Maya and Frank, arguing in a vicious undertone that carried down the tunnel not their meaning but their feeling: Frank’s face was contorted with anger, and Maya as she turned from him was distraught, weeping; she turned back to shout at him, “It was never like that,” and then ran blindly toward Nadia, her mouth twisted into a snarl, Frank’s face a mask of pain. Maya saw Nadia standing there and ran right by her.
Shocked, Nadia turned and walked back to the living chambers. She went up magnesium stairs to the living room in chamber two, and turned on the TV to watch a twenty-four hour news program from Earth, something she very rarely did. After a while she turned down the sound, and looked at the pattern of bricks in the barrel vault overhead. Maya came in and started to explain things to her: there was nothing between her and Frank, it was in Frank’s mind only, he just wouldn’t give up on it even though it had been nothing to begin with; she wanted only John, and it wasn’t her fault that John and Frank were on such bad terms now, it was because of Frank’s irrational desire, it wasn’t her fault, but she felt so guilty because the two men had once been such close friends, like brothers.
And Nadia listened with a careful show of patience, saying “Da, da,” and “I see,” and the like, until Maya was lying flat on her back on the floor, crying, and Nadia was sitting on the edge of a chair staring at her, wondering how much of it was true. And what the argument had really been about. And whether she was a bad friend to distrust her old companion’s story so completely. But somehow the whole thing felt like Maya covering her tracks, practising another manipulation. It was just this: those two distraught faces she had seen down the tunnel had been the clearest evidence possible of a fight between intimates. So Maya’s explanation was almost certainly a lie. Nadia said something soothing to her and went off to bed, thinking, you already have taken too much of my time and energy and concentration with these games, you cost me a finger with them, you bitch!
It was getting toward the end of the long northern spring, and they still had no good supply of water, so Ann proposed to make an expedition to the cap and set up a robot distillery, along the way establishing a route that rovers could follow on automatic pilot. “Come with us,” she said to Nadia. “You haven’t seen anything of the planet yet, just the stretch between here and Chernobyl, and that’s nothing. You missed Hebes and Ganges, and you’re not doing anything new here. Really, Nadia, I can’t believe what a grub you’ve been. I mean why did you come to Mars, after all?”
“Why?”
“Yes, why? I mean there’s two kinds of activities here, there’s the exploration of Mars and then there’s the life support for that exploration. And here you’ve been completely immersed in the life support, without paying the slightest attention to the reason we came in the first place!”
“Well, it’s what I like to do,” Nadia said uneasily.
“Fine, but try to keep some perspective on it! What the hell, you could have stayed back on Earth and been a plumber! You didn’t have to come all this way to drive a goddamn bulldozer! Just how long are you going to go on grubbing away here, installing toilets, programming tractors?”
“All right, all right,” Nadia said, thinking of Maya and all the rest. The square of vaults was almost finished, anyway. “I could use a vacation.”
They took off in three big long-range rovers: Nadia and five of the geologists, Ann, Simon Frazier, George Berkovic, Phyllis Boyle and Edvard Perrin. George and Edvard were friends of Phyllis’s from their NASA days, and they supported her in advocating “applied geological studies", meaning prospecting for rare metals; Simon on the other hand was a quiet ally of Ann’s, committed to pure research and a hands-off attitude. Nadia knew all this even though she had spent very little time alone with any of these people, except for Ann. But talk was talk; she could have named all the allegiances of everyone at base if she had to.
The expedition rovers were each composed of two four-wheeled modules, coupled by a flexible frame: they looked a bit like giant ants. They had been built by Rolls-Royce and a multinational aerospace consortium, and had a beautiful sea green finish. The forward modules contained the living quarters and had tinted windows on all four sides; the aft modules contained the fuel tanks, and sported a number of black rotating solar panels. The eight wire mesh wheels were 2.5 meters high, and very broad.
As they headed north across Lunae Planum they marked their route with little green transponders, dropping one every few kilometers. They also cleared rocks from their path that might disable a robot-driven rover, using the snowplow attachment or the little crane at the front end of the first rover. So in effect they were building a road. But they seldom had to use the rockmoving equipment on Lunae; they drove northeast at nearly their full speed of thirty kilometers an hour for several days straight. They were heading northeast, to avoid the canyon systems of Tempe and Mareotis, and this route took them down Lunae to the long slope of Chryse Planitia. Both these regions looked much like the land around their base camp, bumpy and strewn with small rocks; but because they were heading downhill they often had much longer views than they were used to. It was a new pleasure to Nadia, to drive on and on and see new countryside continually pop over the horizon: hillocks, dips, enormous isolated boulders, the occasional low round mesa that was the outside of a crater.
When they had descended to the lowlands of the northern hemisphere, they turned and drove straight north across the immense Acidalia Planitia, and again ran straight for several days. Their wheel tracks stretched behind them like the first cut of a lawnmower through grass, and the transponders gleamed bright and incongruous among the rocks. Phyllis, Edvard and George talked about making a few side trips, to investigate some indications seen in satellite photos that there were unusual mineral outcroppings near Perepelkin Crater. Ann reminded them irritably of their mission. It made Nadia sad to see that Ann was nearly as distant and tense out here as she was back at base; whenever the rovers were stopped she was outside walking around alone, and she was withdrawn when they sat together in Rover One to eat dinner. Occasionally Nadia tried to draw her out: “Ann, how did all these rocks get scattered around like this?”
“Meteors.”
“But where are the craters?”
“Most are in the south.”
“But how did the rocks get here, then?”
“They flew. That’s why they’re so small. It’s only smaller rocks could be tossed so far.”
“But I thought you told me that these northern plains were relatively new, while the heavy cratering was relatively old.”
“That’s right. The rocks you see here come from late meteor action. The total accumulation of loose rock from meteor strikes is much greater than
