“I want to go back to the Moon with you, Father,” Gib would plead every time Mr. Bromfield came home on a furlough.

“I’m afraid you’re still a little young, Gib,” his father would reply. “Some day you will be able to go out into space with me, but not yet.”

Mr. Bromfield was a construction engineer, and he was helping to build a big spaceport on the Moon. He came home to see his family every six months. Each time he returned, Gib couldn’t wait to meet him at the front door of their prefabricated home.

Gib would shake hands with him like a man and take his bags from him. Then he would step back and admire the tall, handsome man in the glossy black boots and gray uniform of the Space Service. By this time, Mother usually came running up, followed by Sandra, Gib’s little sister.

On Mr. Bromfield’s latest visit, Gib waited until the usual family talk had subsided before he started asking his father about his recent adventures. After Father had brought him up to date, Gib asked the same question he always asked:

“Father, my I go back with you this time for a short visit—just a short one?”

Mr. Bromfield smiled and rumpled Gib’s blond hair. “It’s not the time element, Gib,” he said patiently. “It’s the rigors of space itself, which are much rougher than Captain Rocket on TV would have us believe.”

Gib’s face fell. He had hoped that this time his father would give in and let him go back. Mr. Bromfield could see that his son was disappointed. He stared at Gib thoughtfully for a moment, then spoke again.

“All right, Gib, I’ll put you through S.Q.T. If you pass it and still want to go spaceward, I’ll take you.”

“Gee, do you mean that?” Gib burst out.
