The Murray Leinster Megapack

by Murray Leinster

  By the time the two space craft floated toward India, above an area from which war rockets had been known to rise, there were more little weapons floating with them. One screen of missiles hurtled on before the space tug, and another behind. Anything that came up from Earth would instantly be attacked by dozens of midget ships bent upon suicide.

  Radar probed the space formation, but enemies of the fleet and the Platform very wisely did no more than probe. The Moonship and its attendants went across the Pacific, still rising. Above the longitude of Washington, the space tug left its former post and climbed, nudging the Moonship this way and that. And from behind, the Platform came floating splendidly.

  Tiny figures in space suits extended the incredibly straight lines which were plastic hoses filled with air. Very, very gently indeed, the great, bulbous Platform and the squat, flat Moonship came together and touched. They moored in contact.

  And then the inert small missiles that had floated below, all the way up, flared simultaneously. Their rockets emitted smoke. In fine alignment, they plunged forward through emptiness, swerved with a remarkable precision, and headed out for emptiness beyond the Platform’s orbit. Their function had been to protect the Moonship on its way out. That function was performed. There were too many of them to recover, so they went out toward the stars.

  When their rockets burned out they vanished. But a good hour later, when it was considered that they were as far out as they were likely to go, they began to blow up. Specks of flame, like the tiniest of new stars, flickered against the background of space.

  But Joe and the others were in the Platform by then. They’d brought up mail for the crew. And they were back on duty.

  The Platform seemed strange with the Moonship’s crew aboard. It had been a gigantic artificial world with very few inhabitants. With twenty-five naval ratings about, plus the four of its regular crew, plus the space tug’s complement, it seemed excessively crowded.

  And it was busy. There were twenty-five new men to be guided as they applied what they’d been taught aground about life in space. It was three full Earthdays before the stores intended for the journey to the Moon and the maintenance of a base there really began to move. The tug and the space wagons had to be moored outside and reached only by space suits through small personnel airlocks.

  And there was the matter of discipline. Lieutenant Commander Brown had been put in command of the Platform for experience in space. He was considered to be prepared for command of the Moonship by that experience. So now he turned over command of the Platform to Brent—he made a neat ceremony of it—and took over the ship that would go out to the Moon. He made another ceremony out of that.

  In command of the Moonship, his manner to Joe was absolutely correct. He followed regulations to the letter—to a degree that left Joe blankly uncomprehending. But he wouldn’t have gotten along in the Navy if he hadn’t. He’d tried to do the same thing in the Platform, and it wasn’t practical. But he ignored all differences between Joe and himself. He made no overtures of friendship, but that was natural. Unintentionally, Joe had defied him. He now deliberately overlooked all that, and Joe approved of him—within limits.

  But Mike and Haney and the Chief did not. They laid for him. And they considered that they got him. When he took over the Moonship, Lieutenant Commander Brown naturally maintained naval discipline and required snappy, official naval salutes on all suitable occasions, even in the Platform. And Joe’s gang privately tipped off the noncommissioned personnel of the Moonship. Thereafter, no enlisted man ever saluted Lieutenant Brown without first gently detaching his magnet-soled shoes from the floor. When a man was free, a really snappy salute gave a diverting result. The man’s body tilted forward to meet his rising arm, the upward impetus was one-sided, and every man who saluted Brown immediately made a spectacular kowtow which left him rigidly at salute floating somewhere overhead with his back to Lieutenant Brown. With a little practice, it was possible to add a somersault to the other features. On one historic occasion, Brown walked clanking into a storeroom where a dozen men were preparing supplies for transfer to the Moonship. A voice cried, “Shun!” And instantly twelve men went floating splendidly about the storeroom, turning leisurely somersaults, all rigidly at salute, and all wearing regulation poker faces.

  An order abolishing salutes in weightlessness followed shortly after.

  It took four days to get the transfer of supplies properly started. It took eight to finish the job. Affixing fresh rockets to the outside of the Moonship’s hull alone called for long hours in space suits. During this time Mike floated nearby in a space wagon. One of the Navy men was a trifle overcourageous. He affected to despise safety lines. Completing the hook-on of a landing rocket, he straightened up too abruptly and went floating off toward the Milky Way.

  Mike brought him back. After that there was less trouble.

  Even so, the Moonship and the Platform were linked together for thirteen full days, during which the Platform seemed extraordinarily crowded. On the fourteenth day the two ships sealed off and separated. Joe and his crew in the space tug hauled the Moonship a good five miles from the Platform.

  The space tug returned to the Platform. A blinker signal came across the five-mile interval. It was a very crisp, formal, Navy-like message.

  Then the newly-affixed rockets on the Moonship’s hull spurted their fumes. The big ship began to move. Not outward from Earth, of course. That was where it was going. But it had the Platform’s 12,000 miles per hour of orbital speed. If the bonds of gravitation could have been snapped at just the proper instant, that speed alone would have carried the Moonship all the way to its destination. But they couldn’t. So the Moonship blasted to increase its orbital speed. It would swing out and out, and as the Earth’s pull grew weaker with distance the same weight of rockets would move the same mass farther and farther toward the Moon. The Moonship’s course would be a sort of slowly flattening curve, receding from Earth and becoming almost a straight line where Earth’s and the Moon’s gravitational fields cancelled each other.

  From there, the Moonship would have only to brake its fall against a gravity one-sixth that of Earth, and reaching out a vastly shorter distance.

  Joe and the others watched the roiling masses of rocket fumes as the ship seemed to grow infinitely small.

  “We should’ve been in that ship,” said Haney heavily when the naked eye could no longer pick it out. “We could’ve beat her to the Moon!”

  Joe said nothing. He ached a little inside. But he reflected that the men who’d guided the Platform to its orbit had been overshadowed by himself and Haney and the Chief and Mike. A later achievement always makes an earlier one look small. Now the four of them would be forgotten. History would remember the commander of the Moonship.

  Forgotten? Yes, perhaps. But the names of the four of them, Joe and Haney and the Chief and Mike, would still be remembered in a language Joe couldn’t speak, in a small village he couldn’t name, on those occasions when the Mohawk tribe met in formal council.

  The Chief grumbled. Mike stared out the port with bitter envy.

  “It was a dirty trick,” growled the Chief. “We shoulda been part of the first gang ever to land on the Moon!”

  Joe grimaced. His crew needed to be cured of feeling the same way he did.

  “I wouldn’t say this outside of our gang,” said Joe carefully, “but if it hadn’t been for us four that ship wouldn’t be on the way at all. Haney figured the trick that got us back to Earth the first time, or else we’d have been killed. If we had been killed, Mike wouldn’t have figured out the metal-concrete business. But for him, that Moonship wouldn’t even be a gleam in anybody’s eye. And if the Chief hadn’t blown up that manned rocket we fought in the space wagons, there wouldn’t be any Platform up here to reload and refuel the Moonship. So they left us behind! But just among the four of us I think we can figure that if it hadn’t been for us they couldn’t have made it!”

  Haney grinned slowly at Joe.
The Chief regarded him with irony. Mike said, “Yeah. Haney, and me, and the Chief. We did it all.”

  “Uh-huh,” said the Chief sardonically. “Us three. Just us three. Joe didn’t do anything. Just a bum, he is. We oughta tell Sally he’s no good and she oughta pick herself out a guy that’ll amount to something some day.” He hit Joe between the shoulders. “Sure! Just a bum, Joe! That’s all! But we got a weakness for you. We’ll let you hang around with us just the same! Come on, guys! Let’s get something to eat!”

  The four of them marched down a steel-floored corridor, their magnetic-soled shoes clanking on the plates. Their progress was uncertain and ungainly and altogether undignified. Suddenly the Chief began to bawl a completely irrelevant song to the effect that the inhabitants of the kingdom of Siam were never known to wash their dishes. Haney chimed in, and Mike. They were all very close together, and they were not at all impressive. But it hit Joe very hard, this sudden knowledge that the others didn’t really care. It was the first time it had occurred to him that Haney and Mike and the Chief would rather be left behind with him, as a gang, than go on to individual high achievement in a first landing on the Moon.

  It felt good. It felt real good.

  * * * *

  But that, and all other sources of satisfaction, was wiped out by news that came back from the Moonship a bare six hours later.

  The Moonship was in trouble. The sequence and timing of its rocket blasts were worked out on Earth, and checked by visual and radar observation. The computations were done by electronic brains the Moonship could not possibly have carried. And everything worked out. The ship was on course and its firings were on schedule.

  But then the unexpected happened. It was an error which no machine could ever have predicted, for which statistics and computations could never have compensated. It was ahuman error. At the signal for the final acceleration blast, the pilot of the Moonship had fired the wrong set of rockets.

  Inexperience, stupidity, negligence, excitement—the reason didn’t matter. After years of planning and working and dreaming, one human finger had made a mistake. And the mistake was fatal!

  When the mistake was realized, they’d had sense enough to cut loose the still-firing rockets. But the damage had been done. The ship was still plunging on. It would reach the Moon. But it wouldn’t land in Aristarchus crater as planned. It would crash. If every rocket remaining mounted on the hull were to be fired at the best possible instant, the Moonship would hit near Copernicus, and it would land with a terminal velocity of 800 feet per second—540 miles an hour.

  It could even be calculated that when the Moonship landed, the explosion ought to be visible from Earth with a fairly good telescope. It was due to take place in thirty-two hours plus or minus a few minutes.

  The others got the space tug into the platform’s lock and did things to it, in the way of loading, that its designers never intended, while Joe was calling Earth for calculations. The result was infuriating. The Moonship had taken off for the Moon on the other side of the Platform’s orbit, when it had a velocity of more than 12,000 miles an hour in the direction it wished to go. The Platform and of course the space tug was now on the reverse side of the Platform’s orbit. And of course they now had a velocity of more than 12,000 miles per hour away from the direction in which it was urgently necessary for the space tug to go. They could wait for two hours to take off, said Earth, or waste the time and fuel they’d need to throw away to duplicate the effect of waiting.

  “But we can’t wait!” raged Joe. Then he snapped. “Look here! Suppose we take off from here, dive at Earth, make a near-graze, and let its gravity curve our course! Like a cometary path! Figure that! That’s what we’ve got to do!”

  He kicked off his magnetic-soled shoes and went diving down to the airlock. Over his shoulder he panted an order for the radar-duty man to relay anything from Earth down to him there. He arrived to find Haney and Mike in hot argument over whether it was possible to load on an extra ton or two of mass. He stopped it. They would.

  “Everything’s loaded?” he demanded. “Okay! Space suits! All set? Let’s get out of this lock and start blasting!”

  He drove them into the space tug. He climbed in himself. He closed the entrance port. The plastic walls of the lock bulged out, pulled back fast, and the steering rockets jetted. The space tug came out of the lock. It spun about. It aimed for Earth and monstrous bursts of rocket-trail spread out behind it. It dived.

  Naturally! When a ship from the Platform wanted to reach Earth for atmosphere-deceleration, it was more economical to head away from it. Now that it was the most urgent of all possible necessities to get away from Earth, in the opposite direction to the space tug’s present motion, it was logical to dive toward it. The ship would plunge toward Earth, and Earth’s gravity would help its rockets in the attainment of frenzied speed. But the tug still possessed its orbital speed. So it would not actually strike the Earth, but would be carried eastward past its disk, even though aimed for Earth’s mid-bulge. Yet Earth would continue to pull. As the space tug skimmed past, its path would be curved by the pull of gravity. At the nearest possible approach to Earth, the tug would fire its heaviest rockets for maximum acceleration. And it would swing around Earth’s atmosphere perhaps no more than 500 miles high—just barely beyond the measurable presence of air—and come out of that crazy curve a good hour ahead of the Platform for a corresponding position, and with a greater velocity than could be had in any other way. Traced on paper, the course of the tug would be a tight parabola.

  The ship dived. And it happened that it had left the Platform and plunged deep in Earth’s shadow, so that the look and feel of things was that of an utterly suicidal plunge into oblivion. There was the seeming of a vast sack of pure blackness before the nose of the space tug. She started for it at four gravities acceleration, and Joe got his headphones to his ears and lay panting while he waited for the figures and information he had to have.

  He got them. When the four-gravity rockets burned out, the tug’s crew painstakingly adjusted the ship’s nose to a certain position. They flung themselves back into the acceleration chairs and Joe fired a six-g blast. They came out of that, and he fired another. The three blasts gave the ship a downward speed of a mile and a half a second, and Earth’s pull added to it steadily. The Earth itself was drawing them down most of a 4,000-mile fall, which added to the speed their rockets built up.

  Down on Earth, radar-bowls wavered dizzily, hunting for them to feed them observations of position and data for their guidance. Back on the Platform, members of the crew feverishly made their own computations. When the four in the Space tug were half-way to Earth, they were traveling faster than any humans had ever traveled before, relative to the Earth or the Platform itself. When they were a thousand miles from Earth, it was certain they would clear its edge. Joe proposed and received an okay to fire a salvo of Mark Tens to speed the ship still more. When they burned to the release-point and flashed away past the ports, the Chief and Haney panted up from their chairs and made their way aft.

  “Going to reload the firing-frames,” gasped the Chief.

  They vanished. The space tug could take rockets from its cargo and set them outside its hull for firing. No other ship could.

  Haney and the Chief came back. There was dead silence in the ship, save for a small, tinny voice in Joe’s headphones.

  “We’ll pass Earth 600 miles high,” said Joe in a flat voice. “Maybe closer. I’m going to try to make it 450. We’ll be smack over enemy territory, but I doubt they could hit us. We’ll be hitting better than six miles a second. If we wanted to, we could spend some more rockets and hit escape velocity. But we want to stop, later. We’ll ride it out.”

  Silence. Stillness. Speed. Out the ports to Earthward there was purest blackness. On the other side, a universe of stars. But the blackness grew and grew and grew until it neatly bisected the cosmos itself, and half of everything that was, was blackness. Half was tiny col
ored stars.

  Then there was a sound. A faint sound. It was a moan. It was a howl. It was a shriek.… And then it was a mere thin moan again. Then it was not.

  “We touched air,” said Joe calmly, “at six and a quarter miles per second. Pretty thin, though. At that, we may have left a meteor-trail for the populace to admire.”

  Nobody said anything at all. In a little while there was light ahead. There was brightness. Instantly, it seemed, they were out of night and there was a streaming tumult of clouds flashing past below—but they were 800 miles up now—and Joe’s headphones rattled and he said:

  “Now we can give a touch of course-correction, and maybe a trace of speed.…”

  Rockets droned and boomed and roared outside the hull. The Earth fell away and away and presently it was behind. And they were plunging on after the Moonship which was very, very, very far on before them.

  It was actually many hours before they reached it. They couldn’t afford to overtake it gradually, because they had to have time to work in after contact. But overtaking it swiftly cost extra fuel, and they hadn’t too much. So they compromised, and came up behind the Moonship at better than 2,000 feet per second difference in speed—they approached it as fast as most rifle-bullets travel—and all creation was blotted out by the fumes of the rockets they fired for deceleration.

  Then the space tug came cautiously close to the Moonship. Mike climbed out on the outside of the tug’s hull, with the Chief also in space equipment, paying out Mike’s safety-line. Mike leaped across two hundred yards of emptiness with light-years of gulf beneath him. His metal soles clanked on the Moonship’s hull.

  Then the vision-screen on the tug lighted up. Lieutenant Commander Brown looked out of it, quietly grim. Joe flicked on his own transmitter. He nodded.

  “Mr. Kenmore,” said Brown evenly, “I did not contact you before because I was not certain that contact could be made. How many passengers can you take back to the Platform?”

  Joe blinked at him.
