As Astro followed the Solar Guard captain toward the rocket ship he saw a familiar figure standing near the air lock. A boy with close-cropped blond hair and wearing cadet blues.

"Roger!" yelled Astro joyfully. "Captain Strong, look! It's Roger!"

They quickened their pace and were soon beside the small space vessel that had been blasted out of commission before it could fire a shot. While Roger was telling them of having volunteered for radar operations aboard the ship and of their being disabled by a near miss, Lieutenant Williams suddenly appeared in the air lock and saluted smartly.

"Major Savage has been injured, sir," said Williams. "Since you are the highest ranking officer on the asteroid, are there any orders?"

"I'm not acquainted with your men, or your prison, Williams," replied Strong. "I'll accept the command as a formality but appoint you my chief aid. Carry on and do anything necessary to get things cleared away."

"Very well, sir," said Williams.

"Have communications been destroyed?"

"Yes, sir. Communications was located in the tower, but Cadet Manning has converted the equipment on ship for long-range audio transmission."

"Very good!" said Strong. "As soon as you get a chance, I want you to make out a full report on the attack, including your personal opinion of who attacked us and why."

"I don't know who manned that ship, sir," said Williams, "but I can tell the reason all right. Every prisoner on the asteroid has escaped!"
