СКАЧАТЬ he saw the Earth seemingly at arm's length somewhere off. Not up, not down. Simply out from where he was. It filled all the space that the porthole showed. It was a gigantic mass of white, fleecy specks and spots which would be clouds, and between the whiteness there was a muddy dark greenish color which would be the ocean. Yet it seemed to slide very, very slowly past the window.

      He saw a tanness between the clouds, and it moved inward from the edge of his field of view. He suddenly realized what it was.

      "We've just about crossed the Atlantic," he said in a peculiar astonishment. But it was true the ship had not been aloft nearly as much as half an hour. "Africa's just coming into sight below. We ought to be about 1,200 miles high and still rising fast. That was the calculation."

      He looked again, and then drew himself across to the opposite porthole. He saw the blackness of space, which was not blackness because it was a carpet of jewels. They were infinite in number and variations in brightness, and somehow of vastly more colorings than one noticed from Earth.

      He heard the Chief grunt, and Haney gulp. He was suddenly conscious that his legs were floating rather ridiculously in mid-air with no particular relationship to anything. He saw the Chief rise very cautiously, holding on to the arms of his seat.

      "Better not look at the sun," said Joe, "even though I've put on the glare-shields."

      The Chief nodded. The glare-shields would keep out most of the heat and a very great deal of the ultraviolet the sun gave off. But even so, to look at the sun directly might easily result in a retinal sunburn which could result in blindness.

      The loudspeaker behind Joe's chair clattered. It had seemed muted by the weight of its diaphragm at three gravities. Now it blasted unintelligibly, with no weight at all. Mike threw a switch and took the message.

      "Communications says radar says we're right on course, Joe," he reported nonchalantly, "and our speed's okay. We'll reach maximum altitude in an hour and thirty-six minutes. We ought to be within calculated distance of the Platform then."

      "Good," said Joe abstractedly.

      He strained his eyes at the Earth. They were moving at an extraordinary speed and height. It had been reached by just four human beings before them. The tannishness which was the coast of Africa crept with astonishing slowness toward the center of what he could see.

      Joe headed back to his seat. He could not walk, of course. He floated. He launched himself with a fine air of confidence. He misjudged. He was floating past his chair when he reached down—and that turned his body—and fumbled wildly. He caught hold of the back as he went by, then held on and found himself turning a grandly dignified somersault. He wound up in a remarkably foolish position with the back of his neck on the back of the chair, his arms in a highly strained position to hold him there, and his feet touching the deck of the cabin a good five feet away.

      Haney looked greenish, but he said hoarsely:

      "Joe, don't make me laugh—not when my stomach feels like this!"

      The feeling of weightlessness was unexpectedly daunting. Joe turned himself about very slowly, with his legs floating indecorously in entirely unintended kicks. He was breathing hard when he pulled himself into the chair and strapped in once more.

      "I'll take Communications," he told Mike as he settled his headphones.

      Reluctantly, Mike switched over.

      "Kenmore reporting to Communications," he said briefly. "We have ended our take-off acceleration. You have our course and velocity. Our instruments read—"

      He went over the bank of instruments before him, giving the indication of each. In a sense, this first trip of a ship out to the Platform had some of the aspects of defusing a bomb. Calculations were useful, but observations were necessary. He had to report every detail of the condition of his ship and every instrument-reading because anything might go wrong, and at any instant. Anything that went wrong could be fatal. So every bit of data and every intended action needed to be on record. Then, if something happened, the next ship to attempt this journey might avoid the same catastrophe.

      Time passed. A lot of time. The feeling of unending fall continued. They knew what it was, but they had to keep thinking of its cause to endure it. Joe found that if his mind concentrated fully on something else, it jerked back to panic and the feel of falling. But the crew of the Space Platform—now out in space for more weeks than Joe had been quarter-hours—reported that one got partly used to it, in time. When awake, at least. Asleep was another matter.

      They were 1,600 miles high and still going out and up. The Earth as seen through the ports was still an utterly monstrous, bulging mass, specked with clouds above vast mottlings which were its seas and land. They might have looked for cities, but they would be mere patches in a telescope. Their task now was to wait until their orbit curved into accordance with that of the Platform and they kept their rendezvous. The artificial satellite was swinging up behind them, and was only a quarter-circle about Earth behind them. Their speed in miles per second was, at the moment, greater than that of the Platform. But they were climbing. They slowed as they climbed. When their path intersected that of the Platform, the two velocities should be exactly equal.

      Major Holt's voice came on the Communicator.

      "Joe," he said harshly, "I have very bad news. A message came from Central Intelligence within minutes of your take-off. I—ah—with Sally I had been following your progress. I did not decode the message until now. But Central Intelligence has definite information that more than ten days ago the—ah—enemies of our Space Exploration Project—" even on a tight beam to the small spaceship, Major Holt did not name the nation everybody knew was most desperately resolved to smash space exploration by anybody but itself—"completed at least one rocket capable of reaching the Platform's orbit with a pay-load that could be an atomic bomb. It is believed that more than one rocket was completed. All were shipped to an unknown launching station."

      "Not so good," said Joe.

      Mike had left his post when Joe took over. Now he made a swooping dart through the air of the cabin. The midget showed no signs of the fumbling uncertainty the others had displayed—but he'd been a member of a midget acrobatic team before he went to work at the Shed. He brought himself to a stop precisely at a hand-hold, grinning triumphantly at the nearly helpless Chief and Haney.

      Major Holt said in the headphones: "It's worse than that. Radar may have told the country in question that you are on the way up. In that case, if it's even faintly possible to blast the Platform before your arrival with weapons for its defense, they'll blast."

      "I don't like that idea," said Joe dourly. "Anything we can do?"

      Major Holt laughed bitterly. "Hardly!" he said. "And do you realize that if you can't unload your cargo you can't get back to Earth?"

      "Yes," said Joe. "Naturally!"

      It was true. The purpose of the pushpots and the jatos and the ship's own take-off rockets had been to give it a speed at which it would inevitably rise to a height of 4,000 miles—the orbit of the Space Platform—and stay there. It would need no power to remain 4,000 miles out from Earth. But it would take power to come down. The take-off rockets had been built to drive the ship with all its contents until it attained that needed orbital velocity. There were landing rockets fastened to the hull now to slow it so that it could land. But just as the take-off rockets had been designed to lift a loaded ship, the landing-rockets had been designed to land an empty one.
