As he sized up his position and that of the asteroid, he let out a yell of triumph. His gamble would succeed! He had estimated that going into the direct gravity pull of the sun at the proper moment and lighting off their last tubes would put them into a landing position. The asteroid was moving rapidly, into a new orbit that would intersect the course he and Santos were on. He had planned on the asteroid's change of orbit. In a minute at most they would be back on the rock. His propulsion tube flared out, and he released it. It would travel along with him, but his hands would be free. Then he saw something else. The blast had started the asteroid turning! He reacted instantly. Turning up his communicator he yelled, "Koa! The rock is spinning! Cut the prisoners loose, grab the equipment, and run for it! You'll have to keep running to stay in the shadow. If sunlight hits those fuel tanks or the rocket tubes, they'll explode!" Koa replied tersely, "Got it. We're moving." At least the Connie cruiser couldn't harm them now, Rip thought grimly. He looked for the cruiser and failed to find it for several seconds. It had moved. He finally saw its exhausts some distance away. He forgot his own predicament and grinned. The Connie cruiser had moved, but not because its commander had wanted to. It had been right in the path of the nuclear blast and had been literally shoved away. Then Rip forgot the cruiser. His suit ventilator was whining in the terrific heat, and his whole body was now bathed in perspiration. The sun was getting them. It would be only a short time until the ventilator overloaded and burned out. They had to reach the asteroid before then. The trouble was that there was nothing further he could do about it. He had only air bottles left, and their blast was so weak that the effect wouldn't speed him up much. Nevertheless, he called to Santos and directed him to use his bottles. Santos spoke up. "Sir, we're going to make it." In the same instant, Rip saw that they would land on the dark side. The asteroid was turning over and over. For a second he had the impression that he was looking at a turning globe of the earth, the kind used in elementary school back home. But this gray planet was scarcely bigger than the giant globe at the Space Council building on Terra. He knew he was going to hit hard. The way to keep from being hurt was to turn the vertical energy of his arrival into motion in another direction. As he swept down to the metal surface he started running, his legs pumping wildly in space. He hit with a bone-jarring thud, lost his footing and fell sideways, both hands cradling his helmet. He got to his feet instantly and looked for Santos. "You all right, sir?" Santos called anxiously. "I think the others are over there." He pointed.
