"I have a chance to go with the first research expedition to Venus," he said. You're afraid the glamor would wear off and you would get to hate it on A nod confirmed this. It was the older man's turn to look thoughtful. "You know, I'm sure, 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.

Donley and Bening were lying perfectly still, their "They wanted me to stay until the next relief ship lands," Chapman "Kind of. Who wouldn't be?" "Well, don't let it throw you. They've never been here on the Moon. They don't know what it's like. All they're trying to do is get a good " All they're trying to do," Chapman said sarcastically. "They've got a fat chance."

In a few hours they'd be relieved by members of the Third research group and they'd be on their way back to Earth. That's what happened to guys like Dixon, Chapman thought. On the Moon, Donley was warming himself over his cup, looking thoughtful. Dowden and Bening were struggling into their suits, getting ready to go outside. Dahl was still sitting on his hammock, trying to ignore them. "Think we ought to radio the space station and see if they've left have waited so long for Christmas that they just can't believe it when have, but I think I know what you mean." He warmed up to it as the idea sank in. "Just what the hell are you going to do?" "Nothing very spectacular," Chapman said, smiling. "I'm going to rent a room over Times Square, get a recording of a rikky-tik piano, and Chapman grinned. "Oh, just somebody. What are you going to do, Dick?" "Well, I'm going to do something practical. First of all, I want to turn over all my geological samples to the government. Then I'm going to sell my life story to the movies and then—why, then, I think I'll get drunk!" "They are. And I can see their reasons for it. But who could pass up They ran through it twice. They were beginning to feel it now, Chapman thought. They were going to go home in a little while and the idea was just starting to sink in. getting into their suits. They still had a section of the sky to map investigate. And the time went faster when you kept busy. 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 Only Klein and Chapman were left in the bunker.

People who wouldn't know an atom from an "Same reason you didn't mention your wife. You get to thinking about it." Klein flipped the lid on the specimen box. "Going to get married when Being on the Moon was the opportunity of a lifetime. He thought so much "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 themselves. The Moon's a new environment and you have to learn how to "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 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?" "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." to the Moon. Dowden hadn't needed any help, with Bening along.

The newcomers were impressed and solemn, very much aware of the tremendous responsibility that rested on Donley and the others were all over them. How was it back on Earth? Who had won the series? Was so-and-so still teaching at the university? What was the international situation? Was the sky still blue, was the grass still green, did the leaves still turn color in the autumn, did people still love and cry and were there summer nights when it was too hot to sleep indoors. Chapman sympathized. If he had had any sense, he'd have tried to smuggle something like that up to the Moon instead of his phonograph. at Chapman. "I've always wanted to meet the man who's spent more time here than "Oh, yes, big plans . They're working on unmanned, open-side rockets now that could carry cargo and sheet steel for more bunkers like this. Enable us to enlarge the unit, have a series of bunkers all linked together.
