The Lexman Spacedrive gave man the stars—but at a fantastic price. Interstellar exploration, colonization, and trade became things of reality. The benefits to Earth were enormous. But because of the Fitzgerald Contraction, a man who shipped out to space could never live a normal life on Earth again. Travelling at speeds close to that of light, spacemen lived at an accelerated pace. A nine-year trip to Alpha Centauri and back seemed to... more...

The Celestia, gliding through space toward Titan, major satellite of Saturn, faltered in her course. Her passengers, mostly mining engineers and their wives, stockholders, and a sprinkling of visitors, were aware of a cessation of the heavens' apparent gyrations, due to the halting of the ship's rotation on its axis. At the same time the ship's fictitious gravity, engendered by the centrifugal force of its rotation, ceased, so that passengers,... more...

ayjay Kelvin was sitting in the lounge of the interplanetary cargo vessel Persephone, his feet propped up on the low table in front of the couch, and his attention focused almost totally on the small book he was reading. The lounge itself was cozily small; the Persephone had not been designed as a passenger vessel, and the two passengers she was carrying at the time had been taken on as an accommodation rather than as a money-making proposition.... more...

Compared with a spaceship in distress, going to hell in a handbasket is roomy and slow! The space freighter Queen Dierdre was a great, squat, pockmarked vessel of the Earth-Mars run and she never gave anyone a bit of trouble. That should have been sufficient warning to Mr. Watkins, her engineer. Watkins was fond of saying that there are two kinds of equipment—the kind that fails bit by bit, and the kind that fails all at once. Watkins... more...

"You are General James Rothwell?" Rothwell sighed. "Yes, Commander Aku. We have met several times." "Ah, yes. I recognize your insignia. Humans are so alike." The alien strode importantly across the office, the resilient pads of his broad feet making little plopping sounds on the rug, and seated himself abruptly in the visitor's chair beside Rothwell's desk. He gave a sharp cry, and another alien, shorter, but sporting similar, golden fur,... more...

Chapter ONE The recon-patroller's leg and torso-pads fine-tuned their tensions as Lieutenant Pete O'Hare shifted position. His eyes ranged the banks of flickering lights around him. An aberrant indicator caught his eye and he mind-stroked a sensor control. Satisfied, he moved on; the greens held firm. Planet Pluto arced into view from starboard, half a million kay distant. The mottled moonlet, Charon, orbited the mother planet tightly. Only... more...

The Time Traveller (for so it will be convenient to speak of him) was expounding a recondite matter to us. His grey eyes shone and twinkled, and his usually pale face was flushed and animated. The fire burned brightly, and the soft radiance of the incandescent lights in the lilies of silver caught the bubbles that flashed and passed in our glasses. Our chairs, being his patents, embraced and caressed us rather than submitted to be sat upon, and... more...

Tension eased away as the spaceship settled down on its metallic haunches and they savored a safe planetfall. Ekstrohm fingered loose the cinches of his deceleration couch. He sighed. An exploration camp would mean things would be simpler for him. He could hide his problem from the others more easily. Trying to keep secret what he did alone at night was very difficult under the close conditions on board a ship in space. Ryan hefted his bulk up... more...

Grant Pemberton sat up suddenly in his berth, every sense straining and alert. What was it that had awakened him in the deathly stillness of the space-flier? His right hand slid under the pillow and clutched the handle of his gun. Its firm coolness was a comforting reality. There it was again. A tiny scratching on the door as though someone was fumbling for the slide-switch. Very quietly he sat, waiting, his finger poised against the trigger.... more...

CHAPTER 1 On the morning the radar reported something odd out in space, Lockley awoke at about twenty minutes to eight. That was usual. He'd slept in a sleeping bag on a mountain-flank with other mountains all around. That was not unprecedented. He was there to make a base line measurement for a detailed map of the Boulder Lake National Park, whose facilities were now being built. Measuring a base line, even with the newest of electronic... more...
