"Come on, Astro," muttered the young cadet. "Let's get a bite to eat. I'm starved."

"I was," said the giant Venusian. "But I lost my appetite."

"Boy, do I wish I had Roger here now!"

"Yeah, me too!"

CHAPTER 12

Olympia, the largest colony on Titan, was gripped by a wave of fear. The broad streets were empty; the shops and stores were deserted; and the population waited in line at the spaceport, with their most valuable belongings, for their turn to leave the threatened settlement. Slowly the satellite of Saturn was dying, and through the methane ammonia atmosphere, the glittering rings of the mother planet shone down on her death struggle.

Tom Corbett and Astro walked through the streets silently, overcome by the desolation around them. Many parts of the city were completely abandoned, and the few remaining citizens wore cumbersome oxygen masks as the deadly atmosphere of gas seeped through the force field to reach the ground surface of the satellite.

As the two cadets continued their dismal tour, they could only find one small restaurant open, a self-service food center that required no help. They were the only customers. During the meal they hardly talked, as they watched the slow procession of people outside, heading for the spaceport.

When the two cadets left the restaurant, a jet car suddenly blasted to a stop beside them and a master sergeant, dressed in the scarlet red of the enlisted Solar Guard, jumped out to face them.
