The older man blew a smoke ring and watched it drift toward the air exhaust vent. that psychologists and research men agree that research stations should be staffed by couples. That is, of course, as soon as it's practical." "But that might be a long time!" the very young man protested. "It might be—but sometimes it's sooner than you think. And the goal is worth it." "I suppose so, but—" to himself. Chapman stared at the radio key. Three years on the Moon and they didn't want him to come back. Three years on the Moon and they thought he'd be glad to stay for more. Just raise his salary or give him a bonus, the every-man-has-his-price idea. They probably thought he liked it there. you couldn't take a shower, couldn't brush your teeth, and your kidneys didn't work right. And for double his salary they thought he'd be glad to stay for another year and a half. Or maybe three. He should probably be glad he had the opportunity. The key started to stutter again, demanding an answer. fit of bureaucratic rage. Chapman stuffed a rag under it and ignored "They wanted me to stay until the next relief ship lands," Chapman man to stay on the job a while longer." " All they're trying to do," Chapman said sarcastically. "They've got No, Chapman thought, some of us aren't going back. You aren't. And day of work on the Moon. In a few hours they'd be relieved by members That's what happened to guys like Dixon, Chapman thought. On the Moon, Klein came back with the coffee. Chapman took a cup, gagged, and forced left there twelve hours ago. They should get here"—he looked at his watch—"in about six and a half hours." "Chap, you know, I've been thinking," Donley said quietly. "You've been here just twice as long as the rest of us. What's the first thing you're going to do once you get back?" It hit them, then. Dowden and Bening looked blank for a minute and "I don't know," Chapman said slowly. "I guess I was trying not to think of that. I suppose none of us have. We've been like little kids who have waited so long for Christmas that they just can't believe it when it's finally Christmas Eve." Klein nodded in agreement. "I haven't been here three years like you have, but I think I know what you mean." He warmed up to it as the idea "Nothing very spectacular," Chapman said, smiling. "I'm going to rent Chapman grinned. "Oh, just somebody. What are you going to do, Dick?" be single," Donley said. "They are. And I can see their reasons for it. But who could pass up The phonograph was a small, wind-up model that Chapman had smuggled in They ran through it twice. They were beginning to feel it now, Chapman The others chimed in and Chapman grinned. Yesterday or a week ago they couldn't have done it. He had been there too long and he had hated it Chapman stopped them at the lock. "Remember to check your suits for Donley looked sour. "I've gone out at least five hundred times," he said, "and you check me each time." "And I'd check you five hundred more," Chapman said. "It takes only through one of those and that's it, brother." Donley sighed. "Chap, you watch us like an old mother hen. You see we check our suits, you settle our arguments, you see that we're not bored Only Klein and Chapman were left in the bunker. Klein was at the work Chapman thought a minute. "I think I miss the sky," he said quietly. "Same reason you didn't mention your wife. You get to thinking about it." Chapman was at the port again, staring out at the bleak landscape. "We "Settle down in a small cottage and raise lots of little Chapmans, eh?" Chapman nodded. He put away the box and came over to the port. Chapman moved over so "He died," Chapman said. "He was a good kid, all wrapped up in science. Being on the Moon was the opportunity of a lifetime. He thought so much 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 stay over, I volunteered. I thought the others were so important that Chapman frowned. "Frankly, I hadn't thought of that. I don't believe "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—" 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 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 to the Moon. 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 He was fumbling it badly, Chapman thought. 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. 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." Chapman was standing in front of it. "Check your suits," he said group had been when they had landed. Like Chapman had been in the First. Chapman had gone through it all before. But was Ginny still Ginny? foot square and six inches deep. Chapman watched him curiously. Chapman cut off a single blade with his fingernail and put it between Chapman sympathized. If he had had any sense, he'd have tried to One of the men separated from the group and came over to Chapman. He Chapman nodded and shook hands. They hadn't had a captain on the First "Well, look, Mr. Chapman, is there any place where we can talk together at Chapman. Chapman jerked a thumb toward Dahl. "Ask him. He's in charge now." Chapman nodded. "They could use a little privacy up here." I wanted to talk to you, Chapman. The Commission talked it over and "That's it?" Chapman asked. "The answer is no," Chapman said.
