Nothing out there. Back inside. Over to the northern wall and the Syrian Gate, and out again under the stars. Nothing.

It took them a long time to think of the farm. By then there were about thirty of them in walkers, and they ran down and through the lock and flooded down the farm’s aisles, spreading out, running between crops.

They found him among the radishes. His jacket was pulled over his face, in the standard emergency air pocket; he must have done it unconsciously, because when they rolled him carefully onto one side, they saw a lump behind one ear.

“Get him inside,” Maya said, her voice a bitter croak, “Hurry, get him inside.”

Four of them lifted him. Chalmers cradled John’s head, and his fingers were intertwined with Maya’s. They trotted back up the shallow steps. Through the farm gate they stumbled, back into the heat of the city. One of the Swiss led them to the nearest medical center, already crowded with desperate people. They got John onto an empty bench. His unconscious expression was pinched, determined. Frank tore off his helmet and went to work pulling rank, bulling into the emergency rooms and shouting at the doctors and nurses. They ignored him until one doctor said, “Shut up. I’m coming.” She went into the hallway and with a nurse’s help clipped John into a monitor, then checked him out with the abstracted, absent look doctors have while working: hands at neck and face and head and chest, stethoscope…

Maya explained what they knew. The doctor took down an oxygen unit from the wall, looking at the monitor. Her mouth was bunched into a displeased little knot. Maya sat at the end of the bench, face suddenly distraught. Her domino had long since disappeared.

Frank crouched beside her.

“We can keep working on him,” the doctor said, “but I’m afraid he’s gone. Too long without oxygen, you know.”

“Keep working on him,” Maya said.

They did, of course. Eventually other medical people arrived, and they carted him off to an emergency room. Frank, Maya, Sax, Samantha, and a number of locals sat outside in the hall. Doctors came and went; their faces had the blank look they took on in the presence of death. Protective masks. One came out and shook his head. “He’s dead. Too long out there.”

Frank leaned his head back against the wall.

When Reinhold Messner returned from the first solo climb of Everest, he was severely dehydrated, and utterly exhausted; he fell down most of the last part of the descent, and collapsed on the Rongbuk glacier, and he was crawling over it on hands and knees when the woman who was his entire support team reached him; and he looked up at her out of a delirium, and said “Where are all my friends?”

It was quiet. No sound but the low hum and whoosh that one never escaped on Mars.

Maya put a hand on Frank’s shoulder, and he almost flinched; his throat clamped down to nothing, it really hurt. “I’m sorry,” he managed to say.

She shrugged the remark aside, frowned. She had somewhat the air of the medical people. “Well,” she said, “you never liked him much anyway.”

“True,” he said, thinking it would be politic to seem honest with her at that moment. But then he shuddered and said bitterly, “What do you know about what I like or don’t like.”

He shrugged her hand aside, struggled to his feet. She didn’t know; none of them knew. He started to go into the emergency room, changed his mind. Time enough for that at the funeral. He felt hollow; and suddenly it seemed to him that everything good had gone away.

He left the medical center. Impossible not to feel sentimental at such moments. He walked through the strangely hushed darkness of the city, into the land of Nod. The streets glinted as if stars had fallen to the pavement. People stood in clumps, silent, stunned by the news. Frank Chalmers made his way through them, feeling their stares, moving without thought toward the platform at the top of town; and as he walked he said to himself, Now we’ll see what I can do with this planet.

“Since they’re going to go crazy anyway, why not just send insane people in the first place, and save them the trouble?” said Michel Duval.

He was only half joking; his position throughout had been that the criteria for selection constituted a mind-boggling collection of double binds.

His fellow psychologists stared at him. “Can you suggest any specific changes?” asked the chairman, Charles York.

“Perhaps we should all go to Antarctica with them, and observe them in this first period of time together. It would teach us a lot.”

“But our presence would be inhibitory. I think just one of us will be enough.”

So they sent Michel Duval. He joined a hundred and fifty-odd finalists at McMurdo Station. The initial meeting resembled any other international scientific conference, familiar to them all from their various disciplines. But there was a difference: this was the continuation of a selection process that had lasted for years, and would last another. And those selected would go to Mars.

So they lived in Antarctica for over a year together, familiarizing themselves with the shelters and equipment that were already landing on Mars in robot vehicles; familiarizing themselves with a landscape that was almost as cold and harsh as Mars itself; familiarizing themselves with each other. They lived in a cluster of habitats located in Wright Valley, the largest of Antarctica’s Dry Valleys. They ran a biosphere farm, and then they settled into the habitats through a dark austral winter, and studied secondary or tertiary professions, or ran through simulations of the various tasks they would be performing on the spaceship Ares, or later on the red planet itself; and always, always aware that they were being watched, evaluated, judged.

They were by no means all astronauts or cosmonauts, although there were a dozen or so of each, with many more up north clamoring to be included. But the majority of the colonists would have to have their expertise in areas that would come into play after landfall: medical skills, computer skills, robotics, systems design, architecture, geology, biosphere design, genetic engineering, biology; also every sort of engineering, and construction expertise of several kinds. Those who had made it to Antarctica were an impressive group of experts in the relevant sciences and professions, and they spent a good bit of their time cross-training to become impressive in secondary and tertiary fields as well.

And all their activity took place under the constant pressure of observation, evaluation, judgement. It was necessarily a stressful procedure; that was part of the test. Michel Duval felt that this was a mistake, as it tended to ingrain reticence and distrust in the colonists, preventing the very compatability that the selection committee was supposedly seeking. One of the many double binds, in fact. The candidates themselves were quiet about that aspect of things, and he didn’t blame them; there wasn’t any better strategy to take, that was a double bind for you: it insured silence. They could not afford to offend anyone, or complain too much; they could not risk withdrawing too far; they could not make enemies.

So they went on being brilliant and accomplished enough to stand out, but normal enough to get along. They were old enough to have learned a great deal, but young enough to endure the physical rigors of the work. They were driven enough to excell, but relaxed enough to socialize. And they were crazy enough to want to leave Earth forever, but sane enough to disguise this fundamental madness, in fact defend it as pure rationality, scientific curiosity or something of the sort — that seemed to be the only acceptable reason for wanting to go, and so naturally they claimed to be the most scientifically curious people in history! But of course there had to be more to it than that. They had to be alienated somehow, alienated and solitary enough to not care about leaving everyone they had known behind forever — and yet still connected and social enough to get along with all their new acquaintances in Wright Valley, with every member of the tiny village that the colony would become. Oh, the double binds were endless! They were to be both extraordinary and extra ordinary, at one and the same time. An impossible task, and yet a task that was an obstacle to their heart’s greatest desire; making it the very stuff of anxiety, fear, resentment, rage. Conquering all those stresses…
