The next cadet moved out smoothly, but returned on an angle and had to be snubbed with the safety line before he could click on. The next cadet had trouble orienting himself at all. He receded, his back to the -ship, and seemed to be about to continue in the direction of Draco till the end of time. Hanako tugged gently on the safety line while letting it run through his gloves and turned him around toward the ship. "Ten seconds on the jet, while I keep a strain on the line," he ordered. The safety line kept the cadet straightened out until he got back. "Number three!" called out Hanako.

Matt stepped forward with a feeling of tight excitement. The instructor hooked the safety line and said, "Any questions? Go ahead when ready."

"Okay." Matt crouched, broke his boots free, and stretched out. He steadied himself against the sergeant's knee. In front of him lay the northern constellations. He picked out the Pole Star as a target, then loosened the safety catch of the firing switch in his glove.

"And . . . one!" He felt a soft, steady pressure across his saddle, a shove of not quite ten pounds. Polaris seemed to vibrate to the blasting of the tiny jet. Then the star swung to the left, beyond the ring of the sight.

He pulled in his right arm and right leg. The star swung faster, checked and started back. Cautiously he extended his right-side limbs again-and almost forgot to cut the jet on the count of ten.

He could not see the ship. Earth swam in the velvety darkness off to the right. The silence and aloneness were more intense, more complete, than he had ever experienced.

"Time to turn," said Hanako in his ear.

"Oh-" said Matt, and grabbed his knees.

The heavens wheeled around him. He saw the ship swinging into sight, too late. He checked by starfishing, but it had moved on past. "Take it easy," advised the sergeant. "Don't curl up quite so tight, and catch it on the next time around. There's no hurry."

He drew himself in again, but not so much. The ship came around again, though twice as far away as it had been before. This time he checked before it swung past. The figures crawling on her side were about three hundred feet away and still backing away from him. He got someone's helmet centered in his sight, pressed the switch and began to count.
