Complete Venus Equilateral (1976) SSC

by George O. Smith

  “I’ve designed an electron gun. It is a superpowered, oversized edition of the kind they used to use in kinescope tubes, oscilloscope tubes, and electron microscopes. Since the dingbat is to be used in space, we can leave the works of the gun open and project a healthy stream of electrons at the offending object without the electrons’ being slowed and dispersed by an impending atmosphere.”

  “But that sounds like shooting battleships with a toy gun.”

  “Not so fast on the objections, gal,” said Franks. “I’ve seen a simple oscilloscope tube with a hole in the business end. It was burned right through a quarter-inch of glass because the fellows were taking pix and had the intensity turned up high. The sweep circuit blew a fuse and the beam stopped on one spot. That was enough to puncture the screen.”

  “I see. That was just a small affair.”

  “A nine-inch tube. The electron gun in a nine-inch kinescope tube is only about four inches long and three-quarters of an inch in diameter. Mine, out there in the turret, is six feet in diameter and thirty feet long. I can fire out quite a bundle of electrons from a tube of that size.”

  “It sounds as though you mean business.”

  “I do. This is the right place to do research of that kind. Out here on Venus Equilateral, we’re in a natural medium for an electron gun, and we’ve the power requirements to run it. I can’t think of any place in the system that offers better chances.”

  “When are you going to try it out?”

  “As soon as a meteor comes over the pile, as long as Warren says we’re ready.”

  Jeanne shook her head. “I wish Channing were here. Things are wild enough when you are both working on something screwball, but I could get scared something fierce at the thought of either one of you working without the other.”

  “Why?”

  “You two sort of act as balance wheels to one another’s craziness. Oh, don’t take that word to heart. Everybody on the relay station thinks the world of you two, myself included. ‘Craziness’ in this case means a sort of friendly description of the way your brains work. Both of you dash off on tangents now and then, and when either one of you get off the beam, the other one seems to swing the weight required to bring the lost one back to the fold.”

  “That’s a real mess of mixed metaphors, Jeanne. But I am going to surprise Don hairless when he gets back here and finds that I’ve done what people claimed couldn’t be done. I’m going to be the bird whose bust sits in the Hall of Fame in between Edison, Einstein, Alexander Graham Bell, S. F. B. Morse, and—”

  “Old Man River, Jack Frost, and Little Boy Blue,” laughed Jeanne. “I hope it’s not a bust, Walt.”

  “You mean I should have a whole statue?”

  “I mean, I hope your dream is not a bust.”

  Jeanne left, with Walt right behind her. Franks made his way from the office level to the relay station by way of a not-often-used stairway that permitted him to drop to the outer skin. Above his head were the first levels of apartmental cubicles occupied by the personnel of Venus Equilateral. Out here, Walt had but a scant thickness of steel between him and the void of space.

  Franks came to a room built from outer skin to inner skin and about fifty feet across. He unlocked the door with a key on his watch chain, and entered. Warren was waiting for him.

  “Hi, ordnance expert. We’re ready as soon as they are.

  “How’s she working?”

  “I should know? We’ve been squirting ropes of electrons out to blank space for hours. She gets rid of all right. But have we done any good? I dunno.”

  “Not a meteor in sight, I suppose.”

  “The detector hasn’t blinked once. But when she does, your electron gun will pick it up a thousand miles before it gets here, and will follow the damned thing until it gets a half-thousand miles out of sight.”

  “That sounds fine. It’s a good thing that we don’t have to swivel that mess of tube around a whole arm in actual use. It would take too long. But we’ll put one in each quadrant of a spaceship and devise it so that its working arc will be small enough to make it work. Time enough to find that out after we know if it works.”

  “That’s something that I’ve been wondering about,” said Warren. “Why didn’t we build a small one out here and evacuate the inner skin for a few hundred feet? We could set up a few chunks of iron and squirt electrons at them.”

  “And have the folks upstairs screaming? Nope. I’ve a hunch that when this beam hits something hard, it will create quite a ruckus. It would be fine to have a hunk blown right off the skin, wouldn’t it?”

  “Guess you’re right,” admitted Warren.

  The meteor alarm flashed, and a bell dinged once.

  “Here’s our chance,” snapped Walt. “We’ve about fifteen seconds to work on this one.”

  He looked out of a tiny window, and saw that the big tube had lined up with the tiny model that was its monitor. He sighted through the model, which in itself was a high-powered telescope, and he saw the jagged meteor rushing forward at an angle to the station. It would miss by many miles, but it would offer a good target.

  “Cathode’s hot,” said Warren.

  Walt Franks grasped the power switch and thrust it down part way. Meters leaped up their scales, and from somewhere there came the protesting whine of tortured generators. Through the window, nothing very spectacular was happening. The cathode glowed slightly brighter due to the passage of current through its metal and out of the coated surface. But the electrostatic stresses that filled the gaps between the accelerator and focusing anodes was no more visible than the electricity that runs a toy motor. Its appearance had not changed a bit; but from the meters, Walt Franks knew that megawatts of electronic power, in the shape of high-velocity electrons, were being poured from the cathode, accelerated by the ring anodes, and focused to a narrow beam by the focusing anodes. And from the end of the framework that supported these anodes, a stream of high-velocity electrons poured forth, twelve niches in diameter.

  Through the telescope, the meteor did not seem to be disturbed. It exploded not, neither did it melt. It came on inexorably, and if the inanimate nickel and iron of a meteor can be said to have such, it came on saucily and in utter disregard for the consequences.

  Frantically, Walt cranked the power up higher and higher, and the lights all over the station dimmed as the cathode gun drained the resources of Venus Equilateral.

  Still no effect.

  Then, in desperation, Walt slammed the lower lever down to the bottom notch. The girders strained in the tube from the terrific electrostatic stresses, and for a second Walt was not certain that the meteor was not finally feeling the effects of the electron bombardment.

  He was not to be sure, for the experiment came to a sudden stop.

  An insulator arced where it led the high-voltage lines that fed the anodes through the wall. Immediately it flashed over, and the room filled to the brim with the pungent odor of burning insulation. A medium-voltage anode shorted to one of the high-voltage anodes, and the stress increased in the tube. They broke from the moorings, these anodes, and plunged backward, down the tube toward the cathode. They hit, and it was enough to jar the whole tube backward on the gimbals.

  The shock warped the mounting of the tube, and it flexed slightly, but sufficiently to bring the farthermost and highest-voltage anode into the electron stream. It glowed redly, and the secondary emission rayed back through the series of electrodes, heating them and creating more warpage.

  Then the pyrotechnics stopped. Great circuit breakers crashed open up in the power room hundreds of feet above them, high in the station.

  Walt Franks looked out through the window at the tangled mess that had been a finely machined piece of equipment. He saw the men looking quizzically at it as he turned away from the window, and with a smile that cost him an effort, he said: “All right, so Marconi didn’t WLW on his first try, either. Come on, fellows, and we’ll clean up this mess.”

  With the utt
er disregard that inanimate objects show toward the inner feelings of the human being, the meteor alarm blinked again and the bell rang. The pilot tube swiveled quickly to one side, lining up with the spot in the celestial globe of the meteor detector. In the turret that housed the big tube, motors strived against welded commutators and the big tube tried to follow.

  Walt looked at the pointing tube and said, “Bah! Go ahead and point!”

  Don Channing smiled at Arden. “Mrs. Channing,” he said, “must you persist in keeping me from my first love?”

  Arden smiled winningly. “Naturally. That’s what I’m here for. I intend to replace your first love entirely and completely.”

  “Yeah,” drawled Don, “and what would we live on?”

  “I’ll permit you to attend to your so-called first love during eight hours every day, provided that you remember to think of me every half-hour.”

  “That’s fine. But you really aren’t fair about it. We were on Terra for two weeks. I was just getting interested in a program outlined by one of the boys that works for Interplanet, and what happened? You hauled me off to Mars. We stayed for a week at the Terraland Hotel at Canalopsis and the first time that Keg Johnson came to see us with an idea and a sheaf of papers, you rushed me off to Lincoln Head. Now I’m scared to death that some guy will try to open a blueprint here; at which, I’ll be rushed off to Palanortis Country until someone finds us there. Then it’ll be the Solar Observatory on Mercury or the Big Glass on Luna.”

  Arden soothed Don’s ruffled feelings by sitting on his lap and snuggling. “Dear,” she said in a voice that positively dripped, “we’re on a honeymoon, remember?”

  Don stood up, dumping her to the floor. “Yeah,” he said, “but this is the highest-velocity honeymoon that I ever took!”

  “And it’s the first one I was ever on where the bridegroom took more time admiring beam installations than he took to whisper sweet nothings to his gal. What has a beam transmitter got that I haven’t got?”

  “One: its actions can be predicted. Two: it can be controlled. Three: it never says anything original, but only repeats what it has been told. Four: it can be turned off.”

  “Yeah?” drawled Arden, grinning wisely. “And how about this rumor?”

  “Rumor?” Channing asked innocently.

  “Yes, rumor!” Arden stormed with a chuckle. “Keep you from your first love, me eye. I’ll play second fiddle to nothing, Donald. I’ll just replace your original first love; but I’m too stinking bright to make you forget it entirely. That, my sweet, is why I’ve brought you here. You can go chase the rumor whilst I do a bit of shopping. May I borrow your checkbook?”

  “Rumor?” repeated Channing with some puzzlement, “What rumor?”

  “Rumor has it,” said Arden in hyperbolic tones, “that two gentlemen, by name James Baler and Barney Carroll, who have spent years digging up and studying the ancient Martian artifacts, have recently uncovered a large and strange type of vacuum tube that seems to have been used by the Martians as a means of transmitting power. Since I felt that the time had come for the honeymooners to spend at least eight minutes apart, I insisted upon Lincoln Head for our next stop because Lincoln Head happens to have been the scene of some rare happenings, if rumor—”

  “Oh, nuts.” Channing grinned. “That’s no rumor—”

  “And you let me ramble on,” cried Arden. She caught Don on the point of the chin with a pillow and effectively smothered him. She followed her advantage with a frontal attack that carried him backward across the bed, where she landed on top viciously and proceeded to lambaste him with the other pillow.

  It was proceeding according to plan, this private, good-natured war, until a knock on the door brought a break in operations. Channing struggled out from beneath Arden and went to the door, trying to comb his hair by running spread fingers through it. He went with a sense of failure caused by Arden’s quiet laugh and ^ statement that he resembled a bantam rooster.

  The man at the door apologized, and then said: “I’m Doug Ferris of the Triworld News.”

  “Come in,” said Don, “and see if you can find a place to sit.”

  “Thanks.”

  “I didn’t know that Triworld News was interested in the wedded life of the Channings. Why doesn’t Triworld wait until we find out about it ourselves?”

  “Triworld does not care to pry into the private life of the newlywed Channing family,” Doug laughed. “We, and the rest of the system, do not give a damn whether Mrs. Channing calls you Bunny Bit or Sugar Pie—”

  “Sweetums,” Arden corrected with a gleam in her eye.

  “—we’ve got something big to handle. I can’t get a thing out of the gang at Canalopsis, they’re all too busy worrying.”

  “And so you came here? What do you expect to get out of us? We’re not connected in any way with Canalopsis.”

  “I know,” said Doug, “but you do know space. Look, Channing, the Solar Queen has been missing since yesterday morning!”

  Don whistled.

  “See what I mean? What I want to know is this: what is your opinion on the matter? You’ve lived in space for years, on Venus Equilateral, and you’ve had experience beyond anybody I can reach.”

  “Missing since yesterday morning,” mused Channing. “That means trouble.”

  “That’s what I thought. Now if you were running the spaceport at Canalopsis, what would your own private opinion be?”

  “I don’t know whether I should speak for publication,” said Don.

  “It won’t be official. I’ll corroborate anything you say before it is printed, and so on. But I want an unofficial opinion, too. If you want this withheld, say so, but I still want a technical deduction to base my investigation on. I don’t understand the ramifications and the implications of a missing ship. It is enough to make Keg Johnson’s hair turn gray overnight, though, and I’d like to know what is so bad before I start to turn stones.”

  “Well, keep it off the record until Canalopsis gives you the go-ahead. I can give you an opinion, but I don’t want to sound official.”

  “O.K. Do you suppose she was hit by a meteor shower?”

  “Doubt it like the devil. Meteor detectors are many and interconnected on a spaceship, as well as being alarmed and fused to the nth degree. Any trouble with them will bring a horde of ringing bells all through the ship which would bring the personnel a-running. They just don’t go wrong for no reason at all.”

  “Suppose that so many meteors came from all directions that the factors presented to the autopilot—”

  “No dice. The possibility of a concentration of meteors from all directions all about to pass through a certain spot in space is like betting on two Sundays in a row. Meteors don’t just run in all directions, they have a general drift. And the meteor-detecting equipment would have been able to pick up the centroid of any group of meteors soon enough to lift the ship around it. Why, there hasn’t been a ship hit by a meteor in ten years.”

  “But—”

  “And if it had been,” continued Channing, “the chances are more than likely that the ship wouldn’t have been hit badly enough to make it impossible to steer, or for the crew to shoot out message tubes which would have landed on Canalopsis.”

  “Look, there’s one thing I don’t understand,” said Doug. “Spacecraft are always dodging meteors, yet Venus Equilateral seems immune.”

  “It’s the velocity,” explained Don. “Venus Equilateral is traveling at the same speed as Venus, of course. A spacecraft hits it up in the hundreds of miles per second. Say two hundred and seventy miles per second, which is about ten times the orbital velocity of Venus Equilateral. Then with a given dispersion of meteors throughout space, any spacecraft has ten times the possible chances of encounter, because the ship covers ten times the volume in the same time. Besides, truly missing meteors is a hypothetical problem.”

  “How so?”

  “To avoid only those whose courses will intersect y
ours would demand some sort of course-predicting gear that would read the course of the oncoming meteor and apply it in a space problem to the predicted course of the ship. That’s just too much machinery, Doug. So spacecraft merely turn aside for anything that even looks close. They don’t take any chances at all,” said Channing, “They can’t afford to.”

  “Suppose that the ship ducked a big shower and it went so far out of course that they missed Mars?”

  “That’s out, too,” laughed Channing.

  “Why?”

  “A standard ship of space is capable of hitting it up at about four G all the way from Terra to Mars at Major Opposition and ending up with enough power and spare cathodes to continue to Venus in quadrature, Now, the velocity of the planets in their orbits is a stinking matter of miles per second, while the top speed of a ship in even the shortest passage runs up into four figures per second. You’d be surprised at what velocity you can attain at one G for ten hours.”

  “Yes?”

  “It runs to slightly less than two hundred and fifty miles per second, during which you’ve covered only four million miles. In the shortest average run from Venus to Terra at conjunction, a skimpy twenty-five million miles, your time of travel is a matter of twenty-five hours odd running at the standard two G. Your velocity at turnover—or the halfway point where the ship stops going up from Terra and starts to go down to Venus—is a good cool five hundred miles per second. So under no condition would the ship miss its objective badly enough to cause its complete loss. Why, this business is run so quickly that were it not for the saving in time and money that amounts to a small percentage at the end of each flight, the pilot could head for his planet and approach the planet asymptotically.”

  “You know what you’re doing, don’t you?” asked the reporter.

  “I think so.”

  “You’re forcing my mind into accepting something that has never happened before, and something that has no basis for its—”
