"I'll take the snapper-boat," he stated. "Santos in the gunner's seat. Koa in charge in the landing boat. Dowst pilot. Let's show an exhaust."

He fitted himself into the tight pilot seat of the snapper-boat while Santos climbed in behind. Then, handling the controls with the skill of long practice, he lifted the tiny fighting rocket above the asteroid and waited for the landing boat. When it joined up, Rip led the way to safety. As he cut his exhaust to wait for the explosion, he sighted past the snapper-boat's nose to the asteroid.

Even though both boats had been careful to match velocity with the asteroid as closely as possible, the slight difference remaining caused them to drift sunward. Rip cut his jets in to compensate, and saw Dowst do the same.

Another few miles toward the sun, and the landing boat wouldn't have the power to get away from Sol's gravity. A few miles beyond that, even the powerful little snapper-boat would be caught.

Below, the timer reached zero. A mighty fan of fire shot into space. The asteroid shuddered from the blast, then swerved gradually, picking up speed as well as new direction.

Rip swallowed hard. Now they were committed. They would reach a new perihelion far beyond the limits of safety. P for perihelion and P for peril. In this case, they were the same thing!


CHAPTER FOURTEEN

Between Two Fires

Back on the asteroid, the Planeteers started laying the second atomic charge. Rip selected the spot, found a nearby crystal that would serve to house the bomb, and Kemp started cutting.
