"If that had hit this pipe we'd be dead ducks," Prochaska observed.

"But it didn't hit," Crag corrected, trying to allay any gathering nervousness. "It just means that we're going to have to get going on the rill airlock as soon as possible."

"How will loss of Able affect that?" Nagel asked curiously.

"Only in the matter of size," Crag explained. "The possible loss of a drone was taken into account. The plastiblocks are constructed to make any size shelter possible. We'll start immediately when Baker lands." He looked thoughtfully at the men. "Let's not borrow any trouble."

"Yeah, there's plenty without borrowing any more," Prochaska agreed. He smiled cheerfully. "I vote we all stop worrying and eat."

Another complication arose. Drone Baker would be in orbit the following morning. Prochaska had to be prepared to bring it down. He was busy moving his equipment into one compact corner opposite the commode. He rigged a curtain around it, partly for privacy but mainly to mark off a definite area prohibited to Richter.

The communicator was becoming another problem that harried Crag. A government geologist wanted a complete description of Arzachel's rock structure. A space medicine doctor had a lot of questions about the working of the oxygen-carbon dioxide exchange system. Someone else—Crag was never quite sure who—wanted an exact description of how the Aztec had handled during letdown. In the end he got on the communicator and curtly asked for Gotch.

"Keep these people off our backs until we land Drone Baker," he told him. "It's not headquarters for some damned quiz program."

"You're big news," Gotch placated. "What you tell us will help with future rockets."

"Like a mineral description of the terrain?"
