While Tom, Astro, and Roger swarmed over the vessel, examining the newly designed and odd-looking gear, the veteran spaceman and his young helper stretched out on the concrete ramp and in thirty seconds were asleep.

The Polaris unit quickly checked out Kit's ship as qualified for the race, and then turned, fascinated, to the tangle of pipes, cables, and mechanical gear of the reactor unit and cooling pumps. Tom and Roger were unable to figure out exactly what changes Kit had made, but Astro gazed at the new machinery fondly, almost rapturously. He tried to explain the intricate work to his unit mates, but would stop in the middle of a sentence when a new detail of the construction would catch his eye.

"Come on, Roger," Tom sighed. "Let's go on to the next ship. This lovesick Venusian can catch up with us later."

They turned away and left Astro alone on the power deck, doubtful that he had even noticed their departure.

The trials had been suspended at nightfall, and the ships that had already blasted off left sections of the huge spaceport empty. The day had been a grueling one for the cadets, and Tom and Roger climbed wearily on the nearest slidewalk that would take them back to the Academy grounds. Just as they rode through the main field gate, Roger nudged Tom. "Look! There's Quent Miles up ahead of us," he said. "Isn't he scheduled to blast off in the morning?"

"Yes. Why?" asked Tom.

"He hasn't called us in to inspect his ship yet."

"Maybe he isn't ready yet," said Tom. "Probably still souping it up."

"I've been watching him. He hasn't done very much."

"What do you mean?"
