Naturally, none of this appeared in the look of things. The small ship floated on and on. It reached an altitude 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.
Spaceship 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 spaceship 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 spaceship 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 spacecraft.
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 space.
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 snatched 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 spaceship 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 orbit, when for a time the sunlight that reached it was light which had passed 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 superstitious 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 buttons 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.
