Swenson said, “If you want to step in and climb out of the suit, I’ll take care of the icing.”

“It’s all right,” said Rioz. “I’d just as soon sit here and watch Saturn.”

He sat down at the lip of the pit. There was a six-foot gap between it and the ship. In some places about the circle, it was two feet; in a few places, even merely a matter of inches. You couldn’t expect a better fit out of handwork. The final adjustment would be made by steaming ice gently and letting it freeze into the cavity between the lip and the ship.

Saturn moved visibly across the sky, its vast bulk inching below the horizon.

Rioz said, “How many ships are left to put in place?”

Swenson said, “Last I heard, it was eleven. We’re in now, so that means only ten. Seven of the ones that are placed are iced in. Two or three are dismantled.”

“We’re coming along fine.”

“There’s plenty to do yet. Don’t forget the main jets at the other end. And the cables and the power lines. Sometimes I wonder if we’ll make it. On the way out, it didn’t bother me so much, but just now I was sitting at the controls and I was saying, ‘We won’t make it. We’ll sit out here and starve and die with nothing but Saturn over us.’ It makes me feel—”

He didn’t explain how it made him feel. He just sat there.

Rioz said, “You think too damn much.”
