Sabotage in Space

With a hollow booming sound reminiscent of old eighteenth-and nineteenth-century clock towers, the electronic time tone rang out from the Tower of Galileo, chiming the hour of n...

"We made it," murmured Roger with a note of disbelief in his voice. "We made it!" And then, with the realization that he was still a Space Cadet for at least another term, he tu...

"Get every man that has been in this hangar during the last twenty-four hours and have him brought under guard to the laboratory for psychographs." Commander Walters' face was g...

For four days the two cadets had been aboard the rocket scout, circling in an orbit between Mars and Earth, conducting equipment tests for Dave Barret. They had become bored wit...

Connel knelt beside the limp form of the Space Cadet, calling frantically, praying that the boy would be miraculously unhurt, yet fearing the worst. A few moments later Tom groa...

Startled, Commander Walters glanced up to see Major Connel enter his office, accompanied by Professor Hemmingwell. The thin little man scowled with irritation as he walked right...

"Advance and be recognized," Roger ordered again. Still nothing moved. The cadet glanced around quickly in the direction of the guardhouse where he knew there was a communicator...

Seated in the pilot's chair on the control deck of the rocket cruiser _Polaris_, Major Connel bellowed the order into the intercom as he scanned the many dials on the huge contr...

Connel's bull-throated roar carried through the ship as he stood on the power deck with Astro and shouted to Tom on the control deck. The space torpedo had destroyed the stern o...

The metallic voice of the dispatcher echoed through the waiting room of the subspaceport on the outskirts of Marsport and the passengers began moving toward the field gate, wher...

As the shattering blast of noise pounded against his eardrums, Tom Corbett opened his eyes, blinked, and stared around him. By the dim light from a small window in the wall over...

Professor Hemmingwell's voice rang over the roar of activity in the hangar as the huge new control panel was lifted along the hull to a large hole that had been cut into the sid...

The old man nodded absently, still dazed by the sudden turn of events. Tom hurried past him and met Roger coming down from the radar bridge. "I'm going too!" the blond-haired ca...

This was the dream and goal of every boy in the thrilling year 2354, when mankind had reached out beyond the bounds of Earth and had conquered space, colonizing planets and blaz...

The messenger from the Solar Guard headquarters on Mars repeated the message. "Cadet Corbett has not been in his hotel since last night, sir," he said. "He was seen leaving the...

Professor Hemmingwell stood on the main deck of the giant spaceship staring sadly at the mess of wires and tubes, controls and gauges, switches and filaments, all shattered and...

"Speaking for myself," he said, looking straight at the major, "I'm not afraid of anything that walks. And that includes you, Major Connel. No offense meant, it's just a stateme...

Connel's bull-throated roar blasted through the intercom of the gleaming projectile ship from the power deck where Dave Barret was stationed, up to the radar bridge where Profes...

For nearly six hours Tom had lain in wait in Galaxy Hall, the museum of Space Academy, on the second floor of the Tower building. He was hiding in the tail section of the _Space...

Connel stepped back grimly and turned to Astro and Roger. "All right, boys," he said. "Take him below and see if you can't get some different answers out of him." The hardened s...
