"This is a fine ship," he mused aloud. "One of the finest that scientific brains can build. She's yours. The day you graduate from the Academy, IF you graduate, and I can think of about a thousand reasons why you won't, you'll command an armed rocket cruiser similar to this. As a matter of fact, the only difference between this ship and those that patrol the space lanes now is in the armament."
"Don't we have any arms aboard at all, sir?" asked Tom.
"Small arms, like paralo-ray pistols and paralo-ray rifles. Plus four atomic war heads for emergency use," replied Strong.
Seeing a puzzled expression cross Astro's face, the Solar Guard officer continued, "You haven't studied armament yet, Astro, but paralo rays are the only weapons used by law-enforcement agencies in the Solar Alliance. They work on a principle of controlled energy, sending out a ray with an effective range of fifty yards that can paralyze the nervous system of any beast or human."
"And it doesn't kill, sir?" inquired Astro.
"No, Astro." replied Strong. "Paralyzing a man is just as effective as killing him. The Solar Alliance doesn't believe you have to kill anyone, not even the most vicious criminal. Freeze him and capture him, and you still have the opportunity of making him a useful citizen."
"But if you can't?" inquired Roger dryly.
"Then he's kept on the prison asteroid where he can't harm anyone." Strong turned away abruptly. "But this isn't the time for a general discussion. We've got work to do!"
He walked over to the master control panel and switched the teleceiver screen. There was a slight buzz, and a view of the spaceport outside the ship suddenly came into focus, filling the screen. Strong flipped a switch and a view aft on the Polaris filled the glowing square. The aluminum scaffolding was being hauled away by a jet truck. Again the view changed as Strong twisted the dials in front of him.
"Just scanning the outside, boys," he commented. "Have to make sure there isn't anyone near the ship when we blast off. The rocket exhaust is powerful enough to blow a man two hundred feet, to say nothing of burning him to death."
