The drive to rehabilitate Red Dog became a frenzy in Crag's mind. He drove his crew mercilessly, beset by a terrible sense of urgency. Nor did he spare himself. They rigged lines in the dark of the moon and rotated the rocket on its long axis until the break in the hull was accessible.

Crag viewed it with dismay. It was far longer than he had feared—a splintered jagged hole whose raw torn edges were bent into the belly of the ship. They finally solved the problem by using the hatch door of Drone Charlie as a seal, lining it with sheets of foam from Bandit, whose interior temperature immediately plummeted to a point where it was scarcely livable.

Prochaska bore the brunt of this new discomfort. Confined as he was to the cabin and with little opportunity for physical activity, he nearly froze until he took to living in his space suit.

Crag began planning the provisioning of Red Dog even before he knew it could be repaired. During each trip from Bandit he burdened the men with supplies. Between times he managed to remove the spare oxygen cylinders carried in Drone Charlie. There was still a scant supply in Drone Baker, but he decided to leave those until later.

The problems confronting him gnawed at his mind until each small difficulty assumed giant proportions. Each time he managed to fit the work into a proper mental perspective a new problem or disaster cropped up. He grew nervous and irritable. In his frantic haste to complete the work on Red Dog he found himself begrudging the crew the few hours they took off each day for sleep. Take it easy, he finally told himself. Slow down, Adam. Yet despite his almost hourly resolves to slow down, he found himself pushing at an ever faster pace. Complete Red Dog ... complete Red Dog ... became a refrain in his mind.

Larkwell grew sullen and surly, snapping at Richter at the slightest provocation. Nagel became completely indifferent, and in the process, completely ineffectual. Crag had long realized that the oxygen man had reached his physical limits. Now, he knew, Nagel had passed them. Maybe he was right ... maybe he wouldn't leave the moon.

When the break in Red Dog was repaired, Crag waited, tense and jittery, while Nagel entered the rocket and pressurized it. It'll work, he told himself. It's got to work. The short period Nagel remained in the rocket seemed to extend into hours before he opened the hatch.

"One or two small leaks," he reported wearily. He looked disconsolately at Crag. "Maybe we can locate them—with a little time."

"Good." Crag nodded, relieved. Another crisis past. He ordered Larkwell to start pulling the engines. If things went right....
