little things—like how to stay alive. The day before the Second group came, he went out to finish some work he was interested in. He forgot to check for leaks and whether or not the valve on his tank was all the way closed. We couldn’t get to him in time.”
“He had his walkie-talkie with him?”
“Yes. It worked fine, too. We heard everything that went through his mind at the end.”
Klein’s face was blank. “What’s your real job here, Chap? Why does somebody have to stay for stopover?”
“Hell, lots of reasons, Julius. You can’t get a whole relief crew and let them take over cold. They have to know where you left off. They have to know where things are, how things work, what to watch out for. And then, because you’ve been here a year and a half and know the ropes, you have to watch them to see that they stay alive in spite of themselves. The Moon’s a new environment and you have to learn how to live in it. There’s a lot of things to learn—and some people just never learn.”
“You’re nursemaid, then.”
“I suppose you could call it that.”

Klein said, “You’re not a scientist, are you?”
“No, you should know that. I came as the pilot of the first ship. We made the bunker out of parts of the ship so there wasn’t anything to go back on. I’m a good mechanic and I made myself useful with the machinery. When it occurred to us that somebody was going to have to stay over, I volunteered. I thought the others were so important that it was better they should take their samples and data back to Earth when the first relief ship came.”
“You wouldn’t do it again, though, would you?”
“No, I wouldn’t.”
“Do you think Dahl will do as good a job as you’ve done here?”
Chapman frowned. “Frankly, I hadn’t thought of that. I don’t believe I care. I’ve put in my time; it’s somebody else’s turn now. He volunteered for it. I think I was fair in explaining all about the job when you talked it over among yourselves.”
“You did, but I don’t think Dahl’s the man for it. He’s too young, too much of a kid. He volunteered because he thought it made him look like a hero. He doesn’t have the judgment that an older man would have. That you have.”
Chapman turned slowly around and faced Klein.
“I’m not the indispensable man,” he said slowly, “and even if I was, it wouldn’t make any difference to me. I’m sorry if Dahl is young. So was I. I’ve lost three years up here. And I don’t intend to lose any more.”
Klein held up his hands. “Look, Chap, I didn’t mean you should stay. I know how much you hate it and the time you put in up here. It’s just—” His voice trailed away. “It’s just that I think it’s such a damn important job.”
Klein had gone out in a last search for rock lichens and Chapman enjoyed one of his relatively few moments of privacy. He wandered over to his bunk and opened his barracks bag. He checked the underwear and his toothbrush and shaving kit for maybe the hundredth time and pushed the clothing down farther in the canvas. It was foolish because the bag was already packed and had been for a week. He remembered stalling it off for as long as he could and then the quiet satisfaction about a week before, when he had opened his small gear locker and transferred its meager belongings to the bag.
He hadn’t actually needed to pack, of course. In less than twenty-four hours he’d be back on Earth where he could drown himself in toothpaste and buy more tee shirts than he could wear in a lifetime. He could leave behind his shorts and socks and the outsize shirts he had inherited from—who was it? Driesbach?—of the First group. Dahl could probably use them or maybe one of the boys in the Third.

But it wasn’t like going home unless you packed. It was part of the ritual, like marking off the last three weeks in pencil on the gray steel of the bulkhead beside his hammock. Just a few hours ago, when he woke up, he had made the last check mark and signed his name and the date. His signature was right beneath Dixon’s.
He frowned when he thought of Dixon and slid back the catch on the top of the bag and locked it. They should never have sent a kid like Dixon to the Moon.
He had just locked the bag when he heard the rumble of the airlock and the soft hiss of air. Somebody had come back earlier than expected. He watched the inner door swing open and the spacesuited figure clump in and unscrew its helmet.
Dahl. He had gone out to help Dowden on the Schmidt telescope. Maybe Dowden hadn’t needed any help, with Bening along. Or more likely, considering the circumstances, Dahl wasn’t much good at helping anybody today.
Dahl stripped off his suit. His face was covered with light beads of sweat and his eyes were frightened.
He moistened his lips slightly. “Do—do you think they’ll ever have relief ships up here more often than every eighteen months, Chap? I mean, considering the advance of—”
“No,” Chapman interrupted bluntly. “I don’t. Not at least for ten years. The fuel’s too expensive and the trip’s too hazardous. On freight charges alone you’re worth your weight in platinum when they send you here. Even if it becomes cheaper, Bob, it won’t come about so it will shorten stopover right away.” He stopped, feeling a little sorry for Dahl. “It won’t be too bad. There’ll be new men up here and you’ll pass a lot of time getting to know them.”
“Well, you see,” Dahl started, “that’s why I came back early. I wanted to see you about stopover. It’s that—well, I’ll put it this way.” He seemed to be groping for an easy way to say what he wanted to. “I’m engaged back home. Really nice girl, Chap, you’d like her if you knew her.” He fumbled in his pocket and found a photograph and put it on the desk. “That’s a picture of Alice, taken at a picnic we were on together.” Chapman didn’t look. “She—we—expected to be married when I got back. I never told her about stopover, Chap. She thinks I’ll be home tomorrow. I kept thinking, hoping, that maybe somehow—”
He was fumbling it badly, Chapman thought.
“You wanted to trade places with me, didn’t you, Bob? You thought I might stay for stopover again, in your place?”
It hurt to look in Dahl’s eyes. They were the eyes of a man who was trying desperately to stop what he was about to do, but just couldn’t help himself.
“Well, yes, more or less. Oh, God, Chap, I know you want to go home! But I couldn’t ask any of the others; you were the only one who could, the only one who was qualified!”

Dahl looked as though he was going to be sick. Chapman tried to recall all he knew about him. Dahl, Robert. Good mathematician. Graduate from one of the Ivy League schools. Father was a manufacturer of stoves or something.
It still didn’t add, not quite. “You know I don’t like it here any more than you do,” Chapman said slowly. “I may have commitments at home, too. What made you think I would change my mind?”
Dahl took the plunge. “Well, you see,” he started eagerly, too far gone to remember such a thing as pride, “you know my father’s pretty well fixed. We would make it worth your while, Chap.” He was feverish. “It would mean eighteen more months, Chap, but they’d be well-paid months!”
Chapman felt tired. The good feeling he had about going home was slowly evaporating.
“If you have any report to make, I think you had better get at it,” he cut in, keeping all the harshness he felt out of his voice. “It’ll be too late after the relief ship leaves. It’ll be easier to give the captain your report than try to radio it back to Earth from here.”
He felt sorrier for Dahl than he could ever remember having felt for anybody. Long after going home, Dahl would remember this.
It
