heavily. The beating of his heart became such a heavy pounding that it seemed that his whole body shook with it. He had to do infinitely fine precision steering with hands that weighed pounds and arms that weighed scores of pounds and a body that had an effective weight of almost a quarter of a ton.
And this went on and went on and on for what seemed several centuries.
Then the voice in the speaker said thickly: “Everything is in the clear. In ten seconds you can release your rockets. Shall I count?”
Joe panted, “Count!”
The mechanical voice said, “Seven ... six ... five ... four ... three ... two ... one ... cut!”
Joe pressed the release. The small, unburnt stubs of the take-off rockets went hurtling off toward emptiness. They consumed themselves as they went, and they attained an acceleration of fifty gravities once they were relieved of all load but their own substance. They had to be released lest one burn longer than another. It was also the only way to stop acceleration by solid-fuel rockets. They couldn’t be extinguished. They had to be released.
From intolerably burdensome heaviness, there was abruptly no weight at all in the ship. Joe’s laboring heart beat twice with the violence the weight had called for, though weight had ended. It seemed to him that his skull would crack open during those two heart-beats. Then he lay limply, resting.
There was a completely incredible stillness, for a time. The four of them panted. Haney was better off than Joe, but the Chief was harder hit. Mike’s small body had taken the strain best of all, and he would use the fact later in shrill argument that midgets were designed by nature to be the explorers of space for their bulkier and less spaceworthy kindred.
The ending of the steady, punishing drag was infinitely good, but the new sensation was hardly pleasant. They had no weight. It felt as if they and the ship about them were falling together down an abyss which must have a bottom. Actually, they were falling up. But they felt a physical, crawling apprehension—a cringing from an imaginary imminent impact.
They had expected the sensation, but it was not the better for being understood. Joe flexed and unflexed his fingers slowly. He stirred and swallowed hastily. But the feeling persisted. He unstrapped himself from his seat. He stood up—and floated to the ceiling of the cabin. But there was of course no ceiling. Every way was up and every way was down. His stomach cramped itself in a hard knot, in the instinctive tensity of somebody in free fall.
He fended himself from the ceiling and caught at a hand-line placed there for just this necessity to grip something. In his absorption, he did not notice which way his heels went. He suddenly noticed that his companions, with regard to him, were upside down and staring at him with wooden, dazed expressions on their faces.
He tried to laugh, and gulped instead. He pulled over to the quartz-glass ports. He did not put his hand into the sunlight, but shifted the glare shutters over those ports which admitted direct sunshine. Some ports remained clear. Through one of them 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
