"Ready, Corbett!" called Strong. "You'll be clocked from the second you're on range. One hundred feet—seventy-five—fifty—twenty-five—ten—time!"
As the signal echoed in his blacked-out space helmet, Tom jerked his body around in a sudden violent move, and grasping the valve of the jet unit on his back, he opened it halfway. He waited, holding his breath, expecting to hear Captain Strong correct his course. He counted to ten slowly, and when no correction came over the headphones, he opened the valve wide and blindly shot through space.
Aboard the Polaris, Astro and Roger shouted with joy and Strong could not repress a grin. The tiny figure on the scanner was hurtling straight for the side of the Polaris!
As the image grew larger and larger, anxious eyes swiveled back and forth from the scanner screen to the steady sweeping hand of the chronometer. Roger bit his lip nervously, and Astro's hands trembled.
When Tom reached a point five hundred feet away from the ship, Strong flipped open the audio circuit and issued his first order.
"Range five hundred feet," he called. "Cut jets!"
"You're already here, spaceboy!" yelled Roger into the mike, leaning over Strong's shoulder. The captain silenced him with a glare. No one could speak to the examinee but the testing officer.
Tom closed the valve of his jet unit and blindly jerked himself around again to drift feet first toward the ship. Strong watched this approach closely, silently admiring the effortless way the cadet handled himself in weightless space. When Tom was fifty feet away from the ship, and still traveling quite fast, Strong gave the second order to break his speed. Tom opened the valve again and felt the tug of the jets braking his acceleration. He drifted slower and slower, and realizing that he was close to the hull of the ship, he stretched his legs, striving to make contact. Seconds later he felt a heavy thump at the soles of his feet, and within the ship there was the muffled clank of metal boot weights hitting the metal skin of the hull.
"Time!" roared Strong and glanced at the astral chronometer over his head. The boys crowded around as the Solar Guard captain quickly computed Tom's score. "Nine minutes, fifty-one seconds, and two corrections," he announced, unable to keep the pride out of his voice.
