  • "Perhaps you will not be quite so hasty with your men's lives in the future, Captain?" the doctor said. Professor Schultz was spinning dials. "No contact," the professor said, "No contact at all." That had been six months ago. Three more test rockets had been fired successfully before the urgent report came through from Alaskan Observation Post No. 4. A rocket was coming across the Pole. The strange rocket was tracked and escorted by atomic armed fighters all the way to the Rocket Testing Station where it cut its own motors and gently landed. In the center of a division...

  • Information security does not guarantee the safety of your organization or your information or your computer systems. Information security cannot, in and of itself, provide protection for your information. That being said, information security is also not a black art. There is no sorcery to implementing proper information security and the concepts that are included in information security are not rocket science. In many ways, information security is a mindset. It is a mindset of examining the threats and vulnerabilities of your organization and managing them appropriately.

  • Discovering what lies behind a hill or beyond a neighborhood can be as simple as taking a short walk. But curiosity and the urge to make new dis- coveries usually require people to undertake journeys much more adven- turesome than a short walk, and scientists oft en study realms far removed from everyday observation—sometimes even beyond the present means of travel or vision.

  • Two boys walked down the beach, deep in conversation. Seventeenyear- old Jeff Luty was carrying a carbon-fiber pipe rocket. His best friend, Carlos Tucay, was carrying the launch rod and a cheap bottle of Mieux champagne. Gangly Jeff was a head taller than Carlos. “We’re unobservable now,” said Jeff, looking back down the sand. It was twilight on a clear New Year’s Day in Stinson Beach, California. Jeff ’s mother had rented a cheap cottage in order to get out of their cramped South San Francisco apartment for the holiday, and Carlos had come along.

  • IF YOU will look at any good map of Venus you will see that the land mass called Anlap lies northwest of the island of Vepaja, from which Duare and I had just escaped. On Anlap lies Korva, the friendly country toward which I pointed the nose of our plane. Of course there is no good map of Venus, at least none that I ever have seen; because the scientists of the southern hemisphere of the planet, the hemisphere to which Chance carried my rocket ship, have an erroneous conception of the shape of their world. They believe that Amtor, as they call it, is shaped like a...

  • Russ Evans, Pilot 3497, Rocket Squad Patrol 34, unsnapped his seat belt, and with a slight push floated "up" into the air inside the weightless ship. He stretched himself, and yawned broadly. "Red, how soon do we eat?" he called. "Shut up, you'll wake the others," replied a low voice from the rear of the swift little patrol ship. "See anything?" "Several million stars," replied Evans in a lower voice. "And—" His tone became suddenly severe. "Assistant Murphy, remember your manners when addressing your superior officer. I've a mind to report you.

  • The space-ship Viking—two hundred feet of gleaming metal and polished duralite—lay on the launching platform of New York City's municipal airport. Her many portholes gleamed with light. She was still taking on rocket fuel from a tender, but otherwise all the final stores were aboard. Her helicopters were turning over slowly, one at a time, as they were tested. In the Viking's upper control room Gerry Norton and Steve Brent made a final check of the instrument panels. Both men wore the blue and gold uniform of the Interplanetary Fleet.

  • This acknowledgment is necessary if I am to say thanks to some experts to whom I am indebted. There is Captain Charles Benjamin, who read over the aviation parts of this book with pursed lips and a belligerent attitude toward questionable statements of fact or observation. There is Dr. John Drury Clark, whose authoritative knowledge of rocket fuels was the basis for admitted but not extravagant extrapolation on my part.

  • There were ten passengers in the little pressurized cabin of the electric bus that shuttled between the rocket field and Marsport. Ten men, the driver—and Bruce Gordon. He sat apart from the others, as he had kept to himself on the ten-day trip between Earth and Mars, with the yellow stub of his ticket still stuck defiantly in the band of his hat, proclaiming that Earth had paid his passage without his permission being asked. His big, lean body was slumped slightly in the seat. There was no expression on his face.

  • JON KARYL was bolting in a new baffle plate on the stationary rocket engine. It was a tedious job and took all his concentration. So he wasn't paying too much attention to what was going on in other parts of the little asteroid. He didn't see the peculiar blue space ship, its rockets throttled down, as it drifted to land only a few hundred yards away from his plastic igloo. Nor did he see the half-dozen steel-blue creatures slide out of the peculiar vessel's airlock. It was only as he crawled out of the depths of the rocket power plant...

  • Emergency air lock open!" The tall, broad-shouldered officer, wearing the magnificent black-andgold uniform of the Solar Guard, spoke into a small microphone and waited for an acknowledgment. It came almost immediately. "Cadet Corbett ready for testing," a voice crackled thinly over the loud-speaker. "Very well. Proceed." Seated in front of the scanner screen on the control deck of the rocket cruiser Polaris, Captain Steve Strong replaced the microphone in its slot and watched a bulky figure in a space suit step out of the air lock and drift away from the side of the ship.

  • "Jeff Blake!" Holly O'Toole's knotted hand reached out and grasped the right hand of the passenger descending from the rocket transport. "This is a hell of a night to come home, when a man's been away as long as you have." Jeff Blake laughed, and swung down to his side to stand on the windand rain-swept dock. He towered above O'Toole, lanky and smooth skinned. His face was tanned a deep brown from space travel and little wrinkles curled out from the corners of his mouth. Wrinkles that indicated a willing smile. There was a cheerful warmth of sincerity in his voice....

  • T SEEMED they had argued for years as they were arguing tonight. The man paced back and forth chain-smoking cigarettes; the woman sat motionless, watching him. They glanced at their watches with fearful eyes. They heard, with acutely alert ears, the goings and comings of people in the hall; heard the shattering blast of rockets in the sky above the city. And they argued.

  • Stand by to reduce thrust on main drive rockets!" The tall, broadshouldered officer in the uniform of the Solar Guard snapped out the order as he watched the telescanner screen and saw the Western Hemisphere of Earth looming larger and larger. "Aye, aye, Captain Strong," replied a handsome curly-haired Space Cadet. He turned to the ship's intercom and spoke quickly into the microphone. "Control deck to power deck. Check in!" "Power deck, aye," a bull-throated voice bellowed over the loudspeaker. "Stand by rockets, Astro! We're coming in for a landing...

  • "Stand to, you rocket wash!" A harsh, bull-throated roar thundered over the platform of the monorail station at Space Academy and suddenly the lively chatter and laughter of more than a hundred boys was stilled. Tumbling out of the gleaming monorail cars, they froze to quick attention, their eyes turned to the main exit ramp. They saw a short, squat, heavily built man, wearing the scarlet uniform of the enlisted Solar Guard, staring down at them, his fists jammed into his hips and his feet spread wide apart.

  • "Go on, Astro," shouted the young Space Cadet. "Boot that screwy ball with everything you've got!" The three cadets of the Polaris unit raced down the Academy field toward the mercuryball, a plastic sphere with a vial of mercury inside. At the opposite end of the field, three members of the Arcturus unit ran headlong in a desperate effort to reach the ball first. Astro, the giant Space Cadet from Venus, charged toward the ball like a blazing rocket, while his two unit mates flanked him, ready to block out their opponents and give Astro a clear shot at the ball....
