The compressed air bottles did the trick. He and Santos slowed down as the little jets overcame the inertia that was taking them along with the burning boat. The boat was spiraling now, and burning freely. It moved away from them, its stern jets firing weakly as fuel burned in the tank. Rip took a look toward the enemy cruiser. The assault boat was no longer showing an exhaust. Instead, it was being dragged rapidly away from the Connie cruiser by the pull of the sun. At least they had hit it in time to prevent launching of the atomic guided missiles. Or, he thought, perhaps the enemy had never intended using them. The principal effect, besides killing the Planeteers, would have been to drive the asteroid into the sun at an even faster rate. The enemy assault boat was no longer a menace. Its occupants would be lucky if they succeeded in saving their own lives. [Illustration: Rip and Santos Fell Through Space] Rip and Santos Fell Through Space Rip wondered what the Connie cruiser commander would try now. Only one thing remained, and that was to set the cruiser down on the asteroid. If the Connie tried, he would arrive at just about the time set for releasing the nuclear charge. And that would be the end of the cruiser—and probably of the Planeteers as well. Santos asked coolly, "Lieutenant, wouldn’t you say we’re in sort of a bad spot?" Rip had been so busy sizing up the situation that he hadn’t thought about his own predicament. Now he looked down and suddenly realized that he was floating free in space, a considerable distance above the asteroid, and with only small propulsion tubes for power. He gasped, "Great space! We’re in a mess, Santos." The Filipino corporal asked, still in a calm voice, "How long before we’re dragged into the sun, sir?" Rip stared. Santos had used the same tone he might have used in asking for a piece of Venusian _chru_. An officer couldn’t be less calm, so Rip replied in a voice he hoped was casual, "I wouldn’t worry, Santos. We won’t know it. The heat will get through our suits long before then." In fact, the heat should be overloading their ventilating systems right now. In a few minutes the cooling elements would break down and that would be the end. He listened for the accelerated whine as the ventilating system struggled under the increased heat load, and heard nothing. Funny. Had it overloaded and given out already? No, that was impossible. He would be feeling the heat on his body if that were the case. He looked for an explanation and realized for the first time that they weren’t in the sunlight at all. They were in darkness. His searching glance told him they were in the cone of shadow stretching out from behind the asteroid. The thorium rock was between them and the sun!
