Space Tug

Chapter 5

The ship climbed steeply. It was meeting the Platform after only half a circuit of Earth, while the Platform had climbed upward for three full revolutions. Earth was now 3,000 miles below and appeared as the most gigantic of possible solid objects. It curved away and away to mistiness at its horizons, and it moved visibly as the s.p.a.ceship floated on.

Invisible microwaves flung arrowlike through emptiness. They traveled for thousands of miles, spreading as they traveled, and then struck the strange shape of the Platform. They splashed from it. Some of them rebounded to Earth, where spies and agents of foreign powers tried desperately to make sense of the incredible syllables. They failed.

There was a relay system in operation now, from s.p.a.ceship to Platform to Earth and back again. In the ship Chief Bender, Mohawk and steelman extraordinary, talked to the Shed and to one Charley Red Fox. They talked in Mohawk, which is an Algonquin Indian language, agglutinative, complicated, and not to be learned in ten easy lessons. It was not a language which eavesdroppers were likely to know as a matter of course.

But it was a language by which computations could be asked for, so that a very forlorn hope might be attempted with the best possible chances of success.

Naturally, none of this appeared in the look of things. The small ship floated on and on. It reached an alt.i.tude of 3,500 miles. The Earth was visibly farther away. Behind the ship the Atlantic with its stately cloud-formations was sunlit to the very edge of its being. Ahead, the edge of night appeared beyond India. And above, the Platform appeared as a speck of molten light, quarter-illuminated by the sun above it.

s.p.a.ceship and Platform moved on toward a meeting place. The ship moved a trifle faster, because it was climbing. The speeds would match exactly when they met. The small torpedo-shaped shining ship and the bulging glowing metal satellite floated with a seeming vast deliberation in emptiness, while the most gigantic of possible round objects filled all the firmament beneath them. They were 200 miles apart. It seemed that the huge Platform overtook the shining ship. It did. They were only 50 miles apart and still closing in.

By that time the twilight band of Earth"s surface was nearly at the center of the planet, and night filled more than a quarter of its disk.

By that time, too, even to the naked eye through the ports of the supply-ship the enemy rockets had become visible. They were a thin skein of threads of white vapor which seemed to unravel in nothingness. The vapor curled and expanded preposterously. It could just be seen to be jetting into existence from four separate points, two a little ahead of the others. They came out from Earth at a rate which seemed remarkably deliberate until one saw with what fury the rocket-fumes spat out to form the whitish threads. Then one could guess at a three-or even four-stage launching series, so that what appeared to be mere pinpoints would really be rockets carrying half-ton atomic warheads with an attained velocity of 10,000 miles per hour and more straight up.

The threads unraveled in a straight line aimed at the two metal things floating in emptiness. One was small and streamlined, with inadequate landing-rockets clamped to its body and with stubby fins that had no possible utility out of air. The other was large and clumsy to look at, but very, very stately indeed in its progress through the heavens. They floated smoothly toward a rendezvous. The rockets from Earth came ravening to destroy them at the instant of their intersection.

The little s.p.a.ceship turned slowly. Its rounded bow had pointed longingly at the stars. Now it tilted downward. Its direction of movement did not change, of course. In the absence of air, it could tumble indefinitely without any ill effect. It was in a trajectory instead of on a course, though presently the trajectory would become an orbit. But it pointed nose-down toward the Earth even as it continued to hurtle onward.

The great steel hull and the small s.p.a.ceship were 20 miles apart. An infinitesimal radar-bowl moved on the little ship. Tight-beam waves flickered invisibly between the two craft. The rockets raged toward them.

The ship and the Platform were 10 miles apart. The rockets were now glinting missiles leaping ahead of the fumes that propelled them.

The ship and the Platform were two miles apart. The rockets rushed upward.... There were minute corrections in their courses. They converged....

Flames leaped from the tiny ship. Its landing-rockets spouted white-hot flame and fumes more thick and coiling than even the smoke of the bombs.

The little ship surged momentarily toward the racing monsters. And then----

The rockets which were supposed to let the ship down to Earth flew free--flung themselves unburdened at the rockets which came with deadly intent to the meeting of the two Earth s.p.a.cecraft.

The landing-rockets plunged down at forty gravities or better. They were a dwindling group of infinitely bright sparks which seemed to group themselves more closely as they dwindled. They charged upon the attacking robot things. They were unguided, of necessity, but the robot bombs had to be equipped with proximity fuses. No remote control could be so accurate as to determine the best moment for detonation at 4,000 miles" distance. So the war rockets had to be devised to explode when near anything which reflected their probing radar waves. They had to be designed to be triggered by anything in s.p.a.ce.

And the loosed landing-rockets plunged among them.

They did not detonate all at once. That was mathematically impossible.

But no human eye could detect the delay. Four close-packed flares of pure atomic fire sprang into being between the Platform and Earth. Each was brighter than the sun. For the fraction of an instant there was no night where night had fallen on the Earth. For thousands of miles the Earth glowed brightly.

Then there was a twisting, coiling tumult of incandescent gases, which were s.n.a.t.c.hed away by nothingness and ceased to be.

Then there were just two things remaining in the void. One was the great, clumsy, shining Platform, gigantic in size to anything close by.

The other was the small s.p.a.ceship which had climbed to it and fought for it and defended it against the bombs from Earth.

The little ship now had a slight motion away from the Platform, due to the instant"s tugging by its rockets before they were released.

It turned about in emptiness. Its steering-rockets spouted smoke. It began to cancel out its velocity away from the Platform, and to swim slowly and very carefully toward it.

Making actual contact with the platform was not a matter for instruments and calculations. It had to be done directly--by hand, as it were. Joe watched out the ports and played the controls of the steering jets with a nerve-racked precision. His task was not easy.

Before he could return to the point of rendezvous, the blinding sunlight on the Platform took on a tinge of red. It was the twilight-zone of the satellite"s...o...b..t, when for a time the sunlight that reached it was light which had pa.s.sed through Earth"s atmosphere and been bent by it and colored crimson by the dust in Earth"s air. It glowed a fiery red, and the color deepened, and then there was darkness.

They were in Earth"s shadow. There were stars to be seen, but no sun.

The Moon was hidden, too. And the Earth was a monstrous, incredible, abysmal blackness which at this first experience of its appearance produced an almost superst.i.tious terror. Formerly it had seemed a distant but sunlit world, flecked with white clouds and with sprawling differentiations of color beneath them.

Now it did not look like a solid thing at all. It looked like a hole in creation. One could see ten thousand million stars of every imaginable tint and shade. But where the Earth should be there seemed a vast nothingness. It looked like an opening to annihilation. It looked like the veritable Pit of Darkness which is the greatest horror men have ever imagined, and since those in the ship were without weight it seemed that they were falling into it.

Joe knew better, of course. So did the others. But that was the look of things, and that was the feeling. One did not feel in danger of death, but of extinction--which, in cold fact, is very much worse.

Lights glowed on the outside of the Platform to guide the supply ship to it. There were red and green and blue and harsh blue-white electric bulbs. They were bright and distinct, but the feeling of loneliness above that awful appearance of the Pit was appalling. No small child alone at night had ever so desolate a sensation of isolation as the four in the small ship.

But Joe painstakingly played the b.u.t.tons of the steering-rocket control board. The ship surged, and turned, and surged forward again. Mike, at the communicator, said, "They say slow up, Joe."

Joe obeyed, but he was tense. Haney and the Chief were at other portholes, looking out. The Chief said heavily, "Fellas, I"m going to admit I never felt so lonesome in my life!"

"I"m glad I"ve got you fellows with me!" Haney admitted guiltily.

"The job"s almost over," said Joe.

The ship"s own hull, outside the ports, glowed suddenly in a light-beam from the Platform. The small, brief surges of acceleration which sent the ship on produced tremendous emotional effects. When the Platform was only one mile away, Haney switched on the ship"s searchlights. They stabbed through emptiness with absolutely no sign of their existence until they touched the steel hull of the satellite.

Mike said sharply: "Slow up some more, Joe."

He obeyed again. It would not be a good idea to ram the Platform after they had come so far to reach it.

They drifted slowly, slowly, slowly toward it. The monstrous Pit of Darkness which was the night side of Earth seemed almost about to engulf the Platform. They were a few hundred feet higher than the great metal globe, and the blackness was behind it. They were a quarter of a mile away. The distance diminished.

A thin straight line seemed to grow out toward them. There was a small, bulb-like object at its end. It reached out farther than was at all plausible. Nothing so slender should conceivably reach so far without bending of its own weight. But of course it had no weight here. It was a plastic flexible hose with air pressure in it. It groped for the s.p.a.ceship.

The four in the ship held their breaths.

There was a loud, metallic _clank!_

Then it was possible to feel the ship being pulled toward the Platform by the magnetic grapple. It was a landing-line. It was the means by which the ship would be docked in the giant lock which had been built to receive it.

As they drew near, they saw the joints of the plating of the Platform.

They saw rivets. There was the huge, 30-foot doorway with its valves swung wide. Their searchlight beam glared into it. They saw the metal floor, and the bulging plastic sidewalls, restrained by nets. They saw the inner lock-door. It seemed that men should be visible to welcome them. There were none.

The airlock swallowed them. They touched against something solid. There were more clankings. They seemed to crunch against the metal floor--magnetic flooring-grapples. Then, in solid contact with the substance of the Platform, they heard the sounds of the great outer doors swinging shut. They were within the artificial satellite of Earth.

It was bright in the lock, and Joe stared out the cabin ports at the quilted sides. There was a hissing of air, and he saw a swirling mist, and then the bulges of the sidewall sagged. The air pressure gauge was spinning up toward normal sea-level air pressure.

Joe threw the ready lever of the steering rockets to _Off_. "We"re landed."

There was silence. Joe looked about him. The other three looked queer.

It would have seemed natural for them to rejoice on arriving at their destination. But somehow they didn"t feel that they had.
