The shell struck directly under Rip. He felt himself pushed violently upward, and, at the same moment, he reacted—by hunch and not by reason. He rammed the controls full ahead, and the dying rocket cut space, curving slowly as flaming fuel spurted from the ruptured tanks.

Rip yelled, "Santos! You all right?"

"I think so. Lieutenant, we're on fire!"

"I know it. Get ready to abandon ship."

When the main mass of fuel caught, the rocket would become an inferno. Rip smashed at the escape hatch above his head, grabbed propulsion tubes from the rack, and called, "Now!"

He pulled the release on his harness, stood up on the seat, and thrust with all his leg power. He catapulted out of the burning snapper-boat into space.

Santos followed a second later, and the crippled rocket twisted wildly under the two Planeteers.

"Don't use the propulsion tubes," Rip called. "Slow down with your air bottles." He thrust the tubes into his belt, found his air bottles, and pointed two of them in the direction they had been traveling. He wanted to come to a stop, to let the wild snapper-boat get away from them.

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, burning freely. It moved away from them, its stern jets still firing weakly.

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 it was hit 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.
