Out went control lines one to six, slowly undulating like sleepy snakes as they momentarily lost their tension. Two miles away, the triangular panels began to open lazily, spilling sunlight through the sail. Yet, for a long time, nothing seemed to happen. It was hard to grow accustomed to this slow-motion world, where it took minutes for the effects of any action to become visible to the eye. Then Merton saw that the sail was indeed tipping toward the sun—and that Gossamer’s shadow was sliding harmlessly away, its cone of darkness lost in the deeper night of space.
Long before the shadow had vanished and the disk of the sun had cleared again, he reversed the tilt and brought Diana back on course. Her new momentum would carry her clear of the danger; no need to overdo it, and upset his calculations by side-stepping too far. That was another rule that was hard to learn. The very moment you had started something happening in space, it was already time to think about stopping it.
He reset the alarm, ready for the next natural or man-made emergency; perhaps Gossamer, or one of the other contestants, would try the same trick again. Meanwhile, it was time to eat, though he did not feel particularly hungry. One used little physical energy in space, and it was easy to forget about food. Easy—and dangerous; for when an emergency arose, you might not have the reserves needed to deal with it.
He broke open the first of the meal packets, and inspected it without enthusiasm. The name on the label—spacetasties—was enough to put him off. And he had grave doubts about the promise printed underneath. Guaranteed Crumbless. It had been said that crumbs were a greater danger to space vehicles than meteorites. They could drift into the most unlikely places, causing short circuits, blocking vital jets that were supposed to be hermetically sealed.
Still, the liverwurst went down pleasantly enough; so did the chocolate and the pineapple puree. The plastic coffee bulb was warming on the electric heater when the outside world broke in on his solitude. The radio operator on the Commodore’s launch routed a call to him.
“Dr. Merton? If you can spare the time, Jeremy Blair would like a few words with you.” Blair was one of the more responsible news commentators, and Merton had been on his program many times. He could refuse to be interviewed, of course, but he liked Blair, and at the moment he could certainly not claim to be too busy. “I’ll take it,” he answered.
“Hello, Dr. Merton,” said the commentator immediately. “Glad you can spare a few minutes. And congratulations—you seem to be ahead of the field.”
“Too early in the game to be sure of that,” Merton answered cautiously.
“Tell me, doctor—why did you decide to sail Diana yourself? Just because it’s never been done before?”
“Well, isn’t that a very good reason? But it wasn’t the only one, of course.” He paused, choosing his words carefully. “You know how critically the performance of a sun yacht depends on its mass. A second man, with all his supplies, would mean another five hundred pounds. That could easily be the difference between winning and losing.”
“And you’re quite certain that you can handle Diana alone?”
“Reasonably sure, thanks to the automatic controls I’ve designed. My main job is to supervise and make decisions.”
“But—two square miles of sail! It just doesn’t seem possible for one man to cope with all that!”
Merton laughed. “Why not? Those two square miles produce a maximum pull of just ten pounds. I can exert more force with my little finger.”
“Well, thank you, doctor. And good luck.”
As the commentator signed off, Merton felt a little ashamed of himself. For his answer had been only part of the truth; and he was sure that Blair was shrewd enough to know it.
There was just one reason why he was here, alone in space. For almost forty years he had worked with teams of hundreds or even thousands of men, helping to design the most complex vehicles that the world had ever seen. For the last twenty years he had led one of those teams, and watched his creations go soaring to the stars. (But there were failures that he could never forget, even though the fault had not been his.) He was famous, with a successful career behind him. Yet he had never done anything by himself; always he had been one of an army.
This was his very last chance of individual achievement, and he would share it with no one. There would be no more solar yachting for at least five years, as the period of the quiet sun ended and the cycle of bad weather began, with radiation storms bursting through the solar system. When it was safe again for these frail, unshielded craft to venture aloft, he would be too old. If, indeed, he was not too old already . . .
He dropped the empty food containers into the waste disposal, and turned once more to the periscope. At first, he could find only five of the other yachts; there was no sign of Woomera. It took him several minutes to locate her—a dim, star-eclipsing phantom, neatly caught in the shadow of Lebedev. He could imagine the frantic efforts the Australasians were making to extricate themselves, and wondered how they had fallen into the trap. It suggested that Lebedev was unusually maneuverable; she would bear watching, though she was too far away to menace Diana at the moment.

Now Earth had almost vanished. It had waned to a narrow, brilliant bow of light that was moving steadily toward the sun. Dimly outlined within that burning bow was the night side of the planet, with the phosphorescent gleams of great cities showing here and there through gaps in the clouds. The disk of darkness had already blanked out a huge section of the Milky Way; in a few minutes, it would start to encroach upon the sun.
The light was fading. A purple, twilight hue—the glow of many sunsets, thousands of miles below—was falling across the sail, as Diana slipped silently into the shadow of Earth. The sun plummeted below that invisible horizon. Within minutes, it was night.
Merton looked back along the orbit he had traced now a quarter of the way around the world. One by one he saw the brilliant stars of the other yachts wink out, as they joined him in the brief night. It would be an hour before the sun emerged from that enormous black shield, and through all that time they would be completely helpless, coasting without power.
He switched on the external spotlight and started to search the now darkened sail with its beam. Already, the thousands of acres of film were beginning to wrinkle and become flaccid; the shroud lines were slackening, and must be wound in lest they become entangled. But all this was expected; everything was going as planned.
Forty miles astern, Arachne and Santa Maria were not so lucky. Merton learned of their troubles when the radio burst into life on the emergency circuit.
“Number Two, Number Six—this is Control. You are on a collision course. Your orbits will intersect in sixty-five minutes! Do you require assistance?”
There was a long pause while the two skippers digested this bad news. Merton wondered who was to blame; perhaps one yacht had been trying to shadow the other, and had not completed the maneuver before they were both caught in darkness. Now there was nothing that either could do; they were slowly but inexorably converging, unable to change course by a fraction of a degree.
Yet, sixty-five minutes! That would just bring them out into sunlight again, as they emerged from the shadow of Earth. They still had a slim chance, if their sails could snatch enough power to avoid a crash. There must be some frantic calculations going on, aboard Arachne and Santa Maria.
Arachne answered first; her reply was just what Merton had expected.
“Number Six calling Control. We don’t need assistance, thank you. We’ll work this out for ourselves.”
I wonder, thought Merton. But at least it will be interesting to watch. The first real drama of the race was approaching—exactly above the line of midnight on sleeping Earth.
For the next hour, Merton’s own sail kept him too busy to worry about Arachne and Santa Maria. It was hard to keep a good watch on that fifty million square feet of dim plastic out there in the darkness, illuminated only by his narrow spotlight and the rays of the still di
stant moon. From now on, for almost half his orbit around Earth, he must keep the whole of this immense area edge-on to the sun. During the next twelve or fourteen hours, the sail would be a useless encumbrance; for he would be heading into the sun, and its rays could only drive him backward along his orbit. It was a pity that he could not furl the sail completely, until he was ready to use it again. But no one had yet found a practical way of doing this.
Far below, there was the first hint of dawn along the edge of Earth. In ten minutes, the sun would emerge from its eclipse; the coasting yachts would come to life again as the blast of radiation struck their sails. That would be the moment of crisis for Arachne and Santa Maria—and, indeed, for all of them.
Merton swung the periscope until he found the two dark shadows drifting against the stars. They were very close together—perhaps less than three miles apart. They might, he decided, just be able to make it . . .
Dawn flashed like an explosion along the rim of Earth, as the sun rose out of the Pacific. The sail and shroud lines glowed a brief crimson, then gold, then blazed with the pure white light of day. The needles of the dynamometers began to lift from their zeros—but only just. Diana was still almost completely weightless, for with the sail pointing toward the sun, her acceleration was now only a few millionths of a gravity.
But Arachne and Santa Maria were crowding on all the sail they could manage, in their desperate attempt to keep apart. Now, while there was less than two miles between them, their glittering plastic clouds were unfurling and expanding with agonizing slowness, as they felt the first delicate push of the sun’s rays. Almost every TV screen on Earth would be mirroring this protracted drama; and even now, at this very last minute, it was impossible to tell what the outcome would be.
The two skippers were stubborn men. Either could have cut his sail, and fallen back to give the other a chance; but neither would do so. Too much prestige, too many millions, too many reputations were at stake. And so, silently and softly as snowflakes falling on a winter night, Arachne and Santa Maria collided.
The square kite crawled almost imperceptibly into the circular spider’s web; the long ribbons of the shroud lines twisted and tangled together with dreamlike slowness. Even aboard Diana, busy with his own rigging, Merton could scarcely tear his eyes away from this silent, long-drawn-out disaster.
For more than ten minutes the billowing, shining clouds continued to merge into one inextricable mass. Then the crew capsules tore loose and went their separate ways, missing each other by hundreds of yards. With a flare of rockets, the safety launches hurried to pick them up.
That leaves five of us, thought Merton. He felt sorry for the skippers who had so thoroughly eliminated each other, only a few hours after the start of the race; but they were young men, and would have another chance.
Within minutes, the five had dropped to four. From the very beginning, Merton had had doubts about the slowly rotating Sunbeam. Now he saw them justified.
The Martian ship had failed to tack properly; her spin had given her too much stability. Her great ring of a sail was turning to face the sun, instead of being edge-on to it. She was being blown back along her course at almost her maximum acceleration.
That was about the most maddening thing that could happen to a skipper—worse even than a collision, for he could blame only himself. But no one would feel much sympathy for the frustrated colonials, as they dwindled slowly astern. They had made too many brash boasts before the race, and what had happened to them was poetic justice.
Yet it would not do to write off Sunbeam completely. With almost half a million miles still to go, she might still pull ahead. Indeed, if there were a few more casualties, she might be the only one to complete the race. It had happened before.
However, the next twelve hours were uneventful, as Earth waxed in the sky from new to full. There was little to do while the fleet drifted around the unpowered half of its orbit, but Merton did not find the time hanging heavily on his hands. He caught a few hours’ sleep, ate two meals, wrote up his log, and became involved in several more radio interviews. Sometimes, though rarely, he talked to the other skippers, exchanging greetings and friendly taunts. But most of the time he was content to float in weightless relaxation, beyond all the cares of Earth, happier than he had been for many years. He was—as far as any man could be in space—master of his own fate, sailing the ship upon which he had lavished so much skill, so much love, that she had become part of his very being.
The next casualty came when they were passing the line between Earth and sun, and were just beginning the powered half of the orbit. Aboard Diana, Merton saw the great sail stiffen as it tilted to catch the rays that drove it. The acceleration began to climb up from the microgravities, though it would be hours yet before it would reach its maximum value.
It would never reach it for Gossamer. The moment when power came on again was always critical, and she failed to survive it.
Blair’s radio commentary, which Merton had left running at low volume, alerted him with the news: “Hello, Gossamer has the wriggles!” He hurried to the periscope, but at first could see nothing wrong with the great circular disk of Gossamer’s sail. It was difficult to study it, as it was almost edge-on to him and so appeared as a thin ellipse; but presently he saw that it was twisting back and forth in slow, irresistible oscillations. Unless the crew could damp out these waves, by properly timed but gentle tugs on the shroud lines, the sail would tear itself to pieces.

They did their best, and after twenty minutes it seemed that they had succeeded. Then, somewhere near the center of the sail, the plastic film began to rip. It was slowly driven outward by the radiation pressure like smoke coiling upward from a fire. Within a quarter of an hour, nothing was left but the delicate tracery of the radial spars that had supported the great web. Once again there was a flare of rockets, as a launch moved in to retrieve the Gossamer’s capsule and her dejected crew.
“Getting rather lonely up here, isn’t it?” said a conversational voice over the ship-to-ship radio.
“Not for you, Dimitri,” retorted Merton. “You’ve still got company back there at the end of the field. I’m the one who’s lonely, up here in front.” It was not an idle boast. By this time Diana was three hundred miles ahead of the next competitor, and his lead should increase still more rapidly in the hours to come.
Aboard Lebedev, Dimitri Markoff gave a good-natured chuckle. He did not sound, Merton thought, at all like a man who had resigned himself to defeat.
“Remember the legend of the tortoise and the hare,” answered the Russian. “A lot can happen in the next quarter-million miles.”
It happened much sooner than that, when they had completed their first orbit of Earth and were passing the starting line again—though thousands of miles higher, thanks to the extra energy the sun’s rays had given them. Merton had taken careful sights on the other yachts, and had fed the figures into the computer. The answer it gave for Woomera was so absurd that he immediately did a recheck.
There was no doubt of it—the Australasians were catching up at a fantastic rate. No solar yacht could possibly have such an acceleration, unless—
A swift look through the periscope gave the answer. Woomera’s rigging, pared back to the very minimum of mass, had given way. It was her sail alone, still maintaining its shape, that was racing up behind him like a handkerchief blown before the wind. Two hours later it fluttered past, less than twenty miles away. But long before that, the Australasians had joined the growing crowd aboard the Commodore’s launch.
So now it was a straight fight between Diana and Lebedev—for though the Martians had not given up, they were a thousand miles astern and no longer counted as a serious threat. For that matter, it was hard to see what Lebedev could do to overtake Diana’s lead. But all the way around the second lap—through eclipse again, and the long, slow drift against the sun—Merton felt a growing unease.
He knew the Russian pilots and designers.
They had been trying to win this race for twenty years, and after all, it was only fair that they should, for had not Pyotr Nikolayevich Lebedev been the first man to detect the pressure of sunlight, back at the very beginning of the twentieth century? But they had never succeeded.
And they would never stop trying. Dimitri was up to something—and it would be spectacular.
Aboard the official launch, a thousand miles behind the racing yachts, Commodore van Stratten looked at the radiogram with angry dismay. It had traveled more than a hundred million miles, from the chain of solar observatories swinging high above the blazing surface of the sun, and it brought the worst possible news.
The Commodore—his title, of course, was purely honorary; back on Earth he was Professor of Astrophysics at Harvard—had been half-expecting it. Never before had the race been arranged so late in the season; there had been many delays, they had gambled, and now it seemed they might all lose.
Deep beneath the surface of the sun, enormous forces were gathering. At any moment, the energies of a million hydrogen bombs might burst forth in the awesome explosion known as a solar flare. Climbing at millions of miles an hour, an invisible fireball many times the size of Earth would leap from the sun and head out across space.
The cloud of electrified gas would probably miss Earth completely. But if it did not, it would arrive in just over a day. Spaceships could protect themselves, with their shielding and their powerful magnetic screen. But the lightly built solar yachts, with their paper-thin walls, were defenseless against such a menace. The crews would have to be taken off, and the race abandoned.
