investigated and found the satellite suitable for habitation, with fertile soil and an atmosphere similar to our own. With the aid of a few atmosphere booster stations, it should be as easy for a colonist to live there as he would on Venus—or any tropical planet."

"Where are you going to get the colonists, sir?" asked Strong.

Hardy began to pace back and forth in front of Walters' desk, waving his hands as he warmed up to his subject. "Tonight, on a special combined audioceiver and teleceiver broadcast to all parts of the Solar Alliance, the president of the Solar Council will ask for volunteers—men who will take man's first step through deep space to the stars. It is a step, which, in the thousands of years ahead, will eventually lead to a civilization of Earthmen throughout all space!"

Tom, Roger, and Astro sat in silent awe as they listened to the plans for man to reach toward the stars. Spacemen by nature and adventurers in spirit, they were united in the belief that some day Earthmen would set foot on all the stars and never stop until they had seen the last sun, the last world, the last unexplored corner of the cosmos.

"The colonists," continued Hardy, "will come from all over the system. One thousand of them—the strongest and sturdiest men out of the billions that inhabit the planets around us; one thousand, to live on Roald for a period of seven years."

Tom, his eyes bright, asked, "Won't everybody want to go, sir?"

Walters and Hardy smiled. "We expect a rush, Corbett," answered Walters. "You three and Captain Strong have been selected to aid in screening the applicants."

"Will there be any special tests, sir?" asked Strong. "I have to agree with Corbett that just about everyone will want to go."

"Yes, Strong," said Hardy. "Everyone will want to go. In fact, we estimate that there will be literally millions of applicants!"

Roger emitted a long, low whistle. "It'll take years to screen all of them, sir."

Hardy smiled. "Not really, Manning. The psychographs will eliminate the hundreds of thousands of misfits, the men who will want to go for selfish reasons, who are running away from the past, or are dissatisfied with their lack of success in life and embittered because of failure. We can expect many criminal types. Those will be eliminated easily. We have set a specific quota from each of the satellites, planets, and asteroid colonies. I have already established the stations for the preliminary screening. We will screen the remainder until we have the required thousand."

"What will our part be, sir?" asked Tom.

"Once each applicant has been approved by the psychographs, his background will be thoroughly investigated. We may find criminal types who show the blackest of careers, but who would turn over a new leaf if given the chance and prove to be more valuable than men with the best of backgrounds who merely want to get away from it all. We don't want that kind of colonist. We want people who have faith in the project; people who are not afraid of work and hardships. Your screening job will be simple. Each of you has a special talent which Commander Walters feels is outstanding. Corbett in leadership, administration, and command; Manning in electronics; Astro in atomic power and propulsion. You will talk to the applicants and give them simple tests. An important point in any applicant's favor will be his ability to improvise and handle three, four, or five jobs, where a less imaginative person would do but one. Talk to them, sound them out, and then write your report. Captain Strong will review your opinions and make recommendations to me. I will finally approve or disapprove the applications."

"Will this cost the applicants anything, sir?" asked Roger. "For instance, will the rich applicants have a better chance than the poor?"

Hardy's face turned grim. "Only the people that fit our standards will be allowed to go, Manning. Regardless."

"Yes, sir," said Roger.

"The Solar Alliance," continued Hardy, "has established a fund for this project. Each applicant will be lent as much in material as he needs to establish himself on Roald. If he operates an exchange, for instance, selling clothes, equipment, or food, then the size of his exchange will determine the size of the loan. He will repay the Solar Alliance by returning one-fourth of his profits over a period of seven years. Each colonist will be required to remain on the satellite for that seven-year period. After that, should he leave, he would be required to sell all his rights and property on Roald."

"And the farmers, sir," asked Tom, "and all the rest. Will they all be treated the same way?"

"Exactly the same, according to their individual abilities. Of course we wouldn't take a man who had been a shoemaker and advance him the capital to become a farmer."

"Will the quota of one thousand colonists include women and children?" asked Astro.

"No, but allowances have been made for them. One thousand colonists means one thousand men who can produce. However, a man may take his family," Hardy went on, adding, "providing, of course, that he doesn't mean twenty-three children, aunts, uncles, and so forth."

The three cadets looked at each other dumfounded. The very idea of the project was staggering, and as Strong, Hardy, and Commander Walters began to discuss the details of the screening system, they turned to each other excitedly.

"This is the greatest thing that's happened since Jon Builker made his trip into deep space!" whispered Tom.

"Yeah," nodded Astro, "but I'm scared."

"About what?" asked Roger.

"Having the responsibility of saying No to a feller that wants to go."

The big cadet seemed to be worried and Tom attempted to explain what the job would really be.

"It's not a question of saying an outright No," said Tom. "You just ask the applicant about his experience with motors and reactors to see if he really knows his stuff."

Astro seemed to accept Tom's explanation, but he still seemed concerned as they all turned to Commander Walters, who had finished the discussion around the desk and was giving Captain Strong his orders.

"You and the cadets, along with Governor Hardy, will blast off tonight and go to Venusport for the first screenings." He faced the cadets. "You three boys have a tremendous responsibility. In many cases your decisions might mean the difference between success or failure in this mission. See that you make good decisions, and when you've made them, stick by them. You will be under the direct supervision of Captain Strong and Governor Hardy. This is quite different from your previous assignments, but I have faith in you. See that you handle yourselves like spacemen."

The three cadets saluted sharply, and after shaking hands with their commander, left the room.

Later that evening, their gear packed, the three members of the Polaris unit were checked out of the Academy by the dormitory officer and were soon being whisked along on a slidewalk to the Academy spaceport. As they neared the spacious concrete field, where the mighty fleet of the Solar Guard was based, they could see the rows of rocket cruisers, destroyers, scouts, and various types of merchant space craft, and in the center, on a launching platform, the silhouette of the rocket cruiser Polaris stood out boldly against the pale evening sky. Resting on her directional fins, her nose pointed skyward, her gleaming hull reflecting the last rays of the setting sun, the ship was a powerful projectile ready to blast off for distant worlds.
