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?"
