"All clear on the power deck!" The big Venusian's voice boomed over the loud-speaker. The intercom could be heard all over the ship unless the many speakers were turned off individually.
Tom turned his attention back to the great control panel, and one by one tested the banks of dials, gauges, and indicators that controlled the rocket cruiser. Tom Corbett had wanted to be a space Cadet as long as he could remember. After taking the entrance exams, he had been accepted for the rigid training that would prepare him to enter the ranks of the great Solar Guard. He had met his two unit-mates, Roger and Astro, on his very first day at the Academy, and after a difficult beginning, adjusting to each other's personalities and the discipline of the Academy routine, the three boys had become steadfast friends.
As control-deck cadet and pilot, Tom was head of the unit, second-in-command to Captain Strong. And while he could issue orders to Astro and Roger and expect to be obeyed, the three cadets all spoke their minds when it came to making difficult decisions. This had solidified the three cadets into a fighting, experienced, dependable unit.
Tom made a final check on the gravity generator and turned to the intercom.
"All departments, report!" he called.
"Radar bridge checks in O.K.," replied Roger.
"Power deck checks in on the nose, Tom," reported Astro.
"Right! Stand by! We blast as soon as the skipper gets around."
Tom turned to the teleceiver and switched it on. The screen blurred and then steadied into a view of the spaceport outside. Tom scanned the launching ramp below, and, satisfied it was clear, he switched the teleceiver to the spaceport traffic-control circuit.
"Rocket cruiser Polaris to spaceport control," he called. "Come in, spaceport control. Request orbit clearance."
