Boulton cried in anger, dropped his bar, and charged Burl with his hands outstretched.
Burl swung the wrench, but the strength of the older man tore it from his grasp, hurling it away. The boy tried to dodge, and then the two bodies collided.
The instant the two men touched there was a violent flash of light. Burl felt a shock that left him stunned and reeling. Boulton collapsed in a heap on the floor.
Burl steadied himself, keeping a wary eye on the captain. Boulton sat up slowly, putting a hand to his head. “Boy, that was some kickback,” he muttered. He looked at Burl. “Give me a hand up. We’ve got to get back to the jeep and scram out of here fast. The A-bomb’s already set.”
Burl was startled. He realized in a moment, though, that Boulton recalled nothing of the past few days—his last memory seemed to be of the blast in the Martian basement. But now, the captain was apparently himself again.
Boulton got shakily to his feet. He seemed confused. “How’d I get here, son?” he asked in surprise.
Burl gave a sigh of relief. “I guess you’re all right now. But let’s get the trap door to the control room open. Clyde and Caton have got to get the ship back on course. There’ll be time to explain afterward.”
Half an hour later, when Lockhart had recovered and resumed command, the ship was restored to its proper course. Russ filled Boulton in on what had happened and ventured a guess as to why.
“You must have been given some sort of charge by that globe in the Mars Sun-tap station,” Russ said. “It turned you into a sort of robot—a human body running on a charge of alien energy that responded to the commands of the Sun-tap outfit. Apparently, it took a long time before the charge had complete control of your body. Obviously, it then could act only in some general way—telling you to wreck the ship.
“Now, Burl, your body received a charge a long time ago. Whatever its nature, it counteracted or shorted Boulton’s when you came into contact.”
Both Boulton and Burl thought that made sense. “But,” Burl conjectured, “isn’t it possible that the charge in my own body has also been shorted?”
Russ shrugged. “Maybe. We’ll find out at the next stop. And, incidentally, that’s not going to be on Jupiter itself, but on its moon Callisto. We’ve traced the line of distortions.”
“That’s good news,” said Burl. “I had the feeling you were worried about Jupiter. The planet’s so huge it would have meant real trouble trying to land. The books say its atmosphere is thick, unbreathable, and moves in gale velocity around it.”
Russ nodded. “With Jupiter almost 89,000 miles in diameter, it would have been a tough problem to maneuver outside this ship…in fact, impossible, not to mention the fact that the atmosphere, mostly ammonia and other frigid gases, moves in several independent belts. However, Callisto should be okay.”
“That’s something we know about our opponents, anyway,” said Burl, “They must have physical limitations enough like ours to rule out places where we couldn’t move, either.”
Boulton showed no further effects from his experience. In time, the Magellan drew near Jupiter. Callisto, its fifth satellite outward, moved about the mighty planet at a distance of 1,170,000 miles. It was a large satellite as they go, 3,220 miles in diameter, larger, in fact, than Mercury. But, as Russ explained, it was a queer place in its own fashion.
For despite its size, Callisto was apparently not a solid body as we think of it. Its density totaled only a little more than that of water, its mass half that of the Earth’s Moon—a notoriously porous body.
They bore down on Callisto, matching their speed to its, and swung close to its surface. It had almost no atmosphere, just a thin layer of the heavier gases. It was a belted world, without clearly defined continents or surface markings. Its equatorial zone was one vast, featureless belt of darkish-gray. Its temperate zones were white, with patches of yellow here and there. But its poles were gray again.
“The satellite’s like a huge ball of thin mud that’s never hardened,” said Burl as they studied the strange terrain.
“The equator’s the softest—it seems to be a river of muddy water, hundreds of miles wide—only it can’t be water. Probably semisolidified gases holding dust and grains of matter in suspension,” said Russ. “The temperate zones are the same stuff, only colder, and therefore more stable. A thin crust of frozen gases over a planet-wide ocean of semiliquid substance.”
“The Sun-tap station’s on the southern pole,” said Burl. “That must be solid.”
It was. The poles of Callisto were actually two continent-sized islands of shell. Dry, mudlike stuff, hard as rock, floating on the endless seas of the semiliquid planet.
The station, a ringed setup quite like the one on Earth, stood in the geographic center of the south pole. The Magellan hovered over it while a landing party went down in the four-man rocket plane.
Clyde, Haines and Burl were the landing party. This time, only Burl entered the station after a hole had been blasted in the outer shell. While the redheaded astronomer took samples and made observations, Haines kept watch. Nobody knew what type of defense awaited them here.
Burl found the controls easily enough. He was afraid that he might have lost his physical charge, but it was not so. The controls functioned, the Sun-tap station died. The effect was not very noticeable, for Callisto was already far from the Sun and the thin atmosphere could not diminish the dark sky of outer space. What the great masts caught must have been only the relay from other stations—or perhaps the invisible rays of the distant Sun.
Burl saw no reason to linger, and the three of them gathered up their equipment. As they started back toward the rocket plane, they heard an ominous rumble in the ground.
A sudden spurt of blazing gas shot up from the center of the station. “Duck!” yelled Haines, and they fell flat on the ground. Burl held his hands protectively over his head, as an explosion shook the building.
There was no rain of rocks. Whatever the blast, Callisto’s gravity was too weak to attract the debris that flew high above the station.
“It was an atomic explosion!” Haines shouted into his helmet mike. “They mined the station. Run for it!”
They raced for the rocket plane. As they ran, Burl felt the ground quiver beneath him, and huge cracks began to spread, rippling through the hard ground.
They reached the plane and piled in. Russ took off just as the surface cracked open in a thousand places like an ice sheet breaking in an Arctic thaw.
As they rocketed back to the Magellan, the whole polar cap, an area hundreds of miles around the Sun-tap station, split apart. Great spurts of liquid magma, the liquid gas-dust from the heart of the planet, shot up like fountains. Parts of the shell-like polar continent were disappearing beneath this new ocean.
“Their little atomic bomb shattered the thin crust. The whole polar island will probably sink,” said Russ. “It was a clever trap. They knew what would happen.”
“Saturn next,” said Burl. “What’ll they have set up there?”
They reached the Magellan, loaded the rocket plane aboard, and pulled out, setting their course for the ringed planet. But even as they did so, something was coming from Saturn to meet them.
CHAPTER 14
Rockets Away!
The next lap of their journey was uneventful. Saturn, the next outward planet from the Sun, and the second largest, would present the same problem as Jupiter. This world, famous for its mysterious rings, was about 71,000 miles in diameter and had a large family of satellites—nine in all. The Sun-tap station would be on one of these, Burl thought.
Saturn was also almost as far out from Jupiter as Jupiter itself had been from the Sun. This meant that the trip would be as long for the Magellan as the distance they had already traveled to get to Jupiter. Fortunately the A-G drive was a remarkable thing—it was possible to accelerate to fantastic speeds—in theory, probably right up to the speed of light. And so, where great distances were concerned, the ship simply rushed
its fall through on Saturn’s line of gravitation.
Boulton had fully recovered and showed no lingering signs of the strange electronic charge. Because of the limited size of the crew, Lockhart put the Marine captain back on full duty—he would participate in future landings as if nothing had ever happened.
At the same time, Lockhart cautioned Haines, Burl and Ferrati to keep their eyes on him. It was always possible that the foe’s weapon had made some more lasting mark.
Haines had his group make a new inventory of their weapons. Burl, working with them in a space suit, in the partially protected region of the cargo hull, was surprised at the variety. There was a second rocket plane, a two-man outfit. In addition, they had a large store of offensive weapons, including a small but formidable supply of atomic explosives.
Haines gave Burl and Ferrati—who were new to military weapons—brief introductory lectures on their use. Burl saw just what a hand-sized, tactical atomic shell looked like and how it worked. He learned how to operate the heavy-caliber rocket gun which hurled this tiniest of atomic bombs.
And so the time passed, and the amazing disc of Saturn began to grow in their viewplates. It was banded, much like Jupiter, and its brilliant rings surrounded it with a mystic halo that set it apart from all the other worlds of the Sun’s family.
Burl was watching Saturn through the largest of the nose viewplates when he thought that he saw a black dot crossing its face. He had located the known moons of Saturn and this was not one of them. Excited, he called Russell Clyde. “Could it be a tenth satellite?” he asked, pointing out the tiny dot.
Russ squinted his eyes; then, calculating mentally, he shook his head, “I don’t think so. It looks to me more like something that’s in space between us and Saturn. In fact—it must be fairly close to us for us to see it at all.” He turned to Lockhart who was at the control panel with Oberfield.
“You’d better have a look. Could be a giant meteor coming in our direction.”
“We’re moving mighty fast,” commented Oberfield. “It should have passed us already if it were a meteor. Instead, it seems to be maintaining the same distance—neither growing larger nor smaller. Acts very odd for a natural body.”
“Uh, uh,” said Lockhart. “This calls for caution.” He quickly went back to the controls, pressed the general alarm button, then called into the intercom. “All hands to emergency stations. Haines and party, please prepare defensive positions.”
“This means me,” gulped Burl, and scooted down the central hatch, almost colliding with Caton and Shea on their way to the engine room. He met Haines, and, with neat dispatch, all four slipped into space suits. Then out through the cargo hold to posts by escape hatches.
Burl and Haines, at the main entry port, unlimbered the long rocket launcher that had been set up in the passageway. Haines placed three shells of differing strength in position.
They heard through their helmet phones that the mysterious dot was drawing closer. Haines set up one of the launching racks, which was equipped with a telescopic sighter, and peered through the eyepiece. Apparently he caught it, for he grunted, then motioned to Burl to take a look.
It was no natural object. It was the shape of a dumbbell—two spheres joined together by a short middle bar. One sphere was a deep, golden color, the other a bluish-silver, the connecting rod a coppery metal.
“The pattern of spheres certainly suggests the Sun-tappers to me,” said Burl. Haines murmured his agreement.
Lockhart’s voice came on the phones. “We’ve decided it’s one of the Sun-tapper ships. We’re not going to wait to make sure. Before we left Earth, I can now inform you, I received a directive from the President to regard the builders of these Sun-tap stations as active enemies. My orders are that we are not to attempt to undertake peaceful contact, but are to treat them on sight as armed foes in the field. To do otherwise is to risk Earth’s last active defense—this ship.
“I think I don’t have to argue this further, considering our recent experiences.” His voice hesitated, then rang out firmly, “Haines, you can commence firing at will!”
Haines clicked his tongue and reached for one of the shells. “Okay, Burl, aim at her direct. This one’s got a proximity nose that’ll beam at her and drive itself where ever she ducks.”
He slid the rocket shell into the launcher, Burl sighted, and then Haines pressed the trigger. There was a whoosh of fire and a flare from the launcher’s nose. A minute spark winged into the darkness toward the spot, still many miles away, where the strange ship hung.
They watched with bated breath. Suddenly there was a flash of light from the other ship—a vivid lightning bolt which leaped out and flared up briefly in space. Then darkness again.
“They fired a burst of energy at us. It hit the rocket shell instead,” said Haines. “Well, now we know. They use bolts of pure energy—something like the one they fired at Boulton.”
He fitted another shell into the launcher, and fired again. Again a spark winged its way, and the bolt of energy burst out to detonate the shell. Burl whistled. “How did they spot it so fast?” he asked.
“I don’t think they did. They’re firing at us—the rocket shell only happened to be between,” snapped Haines.
“Ferrati,” he called into his mike, “fire a shrapnel shell at them when I say the word. Advise me when ready!”
Ferrati’s voice snapped back. “Right you are, sir. Here it is now, one minute—okay, on target!”
While Ferrati and Boulton were readying their shot from the lower cargo port near the tail of the ship, Haines and Burl had been fitting the largest of their shells into their own launcher. They aimed it carefully at the front-most sphere of the enemy.
“Ferrati, fire!” cried Haines, and then slowly counted to five and pressed the stud of his own launcher.
There was a momentary flicker as Ferrati’s rocket shell raced forth below. Then, after a definite time lapse, the exhaust of Haines’ heavy shell appeared.
“The shrapnel shell is segmented and doesn’t have a proximity guide,” Haines explained. “As soon as it’s on its way, the nose comes apart into a dozen small shells, each with a standard explosive charge. The shell we used has an atomic bomb warhead and is on proximity guide. It’ll chase that ship to the ends of the system if they don’t blast it first.”
He paused. There was another bolt of raw energy from the dumbbell-shaped craft, and this time a series of flares in the space between—the shrapnel charges had been touched off. Burl held his breath.
“I figure it takes them a while to recharge their gun,” said Haines. “Our own blockbuster should get there before they fire again.”
Then suddenly there came a sharper flare of brilliant light. For an instant Burl was blinded by the glare. When he recovered, he peered avidly through the telescopic sighter. He saw the ship, but where there had been a golden sphere there was now only a shattered fragment of twisted metal.
The enemy ship changed before his eyes. The remaining silvery sphere glowed brighter, and took on a golden hue. Then it seemed as if the ship were growing smaller. He realized finally that it was retreating.
Burl gave an involuntary shout, and in his earphones he heard the same shouts of triumph from every voice on the ship.
Although it might have been possible to pursue the battered enemy ship, the Magellan did not try. They were still on course for Saturn and were not going to deviate.
They reached Saturn after several more days. Matching their great speed with that of the ringed world in its orbit took time, and then they began their survey.
As they had suspected, the Sun-tap station was on one of the moons. The moon was called Iapetus, the third largest of Saturn’s family. It was about eight hundred miles in diameter and the next to the farthest satellite from Saturn. Russ was disappointed that they hadn’t picked Titan, the biggest moon of all. Titan was over two thousand miles wide and appeared to have an atmosphere of methane.
The view of Saturn was
awesome, even from Iapetus’ orbit two million miles away. Burl knew it would be a sight unparalleled in the system. The great broad rings, composed of innumerable tiny particles of metal, stone, and possibly ice, encircled it as if held there by an invisible hand. They were, he knew, the particles of a moon that had either come too close to Saturn’s great gravitational pull to hold its shape, or else had never escaped far enough to congeal as one solid mass.
Iapetus was a solid world, though. A rocky body, it had a dull gleam, and was streaked here and there with layers of white and yellow, where veins of frozen gases lay forever upon the frigid surface. No atmosphere veiled the surface nor softened the harsh, jagged mountains and clefts of this forbidding little subplanet.
The Sun-tap station stood in plain sight on a high plateau near a polar region. The Magellan hovered over it while Lockhart held a council of war.
“I don’t see what’s to be gained by attempting a landing party,” he said. “We’ve taken all the readings and pictures of the other stations—and we’ve had a couple of narrow escapes. They’ve probably mined this one, and they have had plenty of time to prepare a trap. I’m in favor of simply dropping an H-bomb on it and leaving.”
After a brief discussion, with only perfunctory objections from Clyde and Oberfield who, as astronomers, wanted to land to take other readings, the decision was carried.
The Magellan swung up a couple of hundred miles above the Sun-tappers’ plateau. Haines and his crew loaded the bulky H-bomb into the main launcher in the tail of the ship. Then the Magellan aimed itself at the target, and the rocket-driven bomb roared out.
Down it sped, zeroing in on the wall of the station. There was a blinding flash, a glare as brilliant as that of the Sun itself, as it hit square on the mark. This time Burl watched through carefully shielded viewscreens. The scene was obscured by a wide-flung cloud of white—tens of thousands of cubic feet of satellite rock turned instantaneously into dust particles. After the dust cleared away, they saw only a gaping crater where the plateau had been—a volcanic hole, miles wide and glowing red, from which spread vast, deep cracks throughout the entire visible hemisphere of the moon.
