A whole generation of research by heroic but unsung volunteers had gone into the design of the washroom, and it was now considered to be more or less foolproof. Floyd investigated it soon after free fall had begun. He found himself in a little cubicle with all the fittings of an ordinary airline toilet, but illuminated with a red light that was very harsh and unpleasant to the eye. A notice printed in prominent letters announced: MOST IMPORTANT! FOR YOUR OWN COMFORT, PLEASE READ THESE INSTRUCTIONS CAREFULLY!

  Floyd sat down (one still tended to do so, even when weightless) and read the notice several times. When he was sure that there had been no modifications since his last trip, he pressed the START button.

  Close at hand, an electric motor began to whirr, and Floyd felt himself moving. As the notice advised him to do, he closed his eyes and waited. After a minute, a bell chimed softly and he looked around.

  The light had now changed to a soothing pinkish-white, but, more important, he was under gravity again. Only the faintest vibration revealed that it was a spurious gravity, caused by the carrousel-like spin of the whole toilet compartment. Floyd picked up a piece of soap, and watched it drop in slow motion; he judged that the centrifugal force was about a quarter of a normal gravity. But that was quite enough; it would ensure that everything moved in the right direction, in the one place where this mattered most.

  He pressed the STOP FOR EXIT button, and closed his eyes again. Weight slowly ebbed as the rotation ceased, the bell gave a double chime, and the red warning light was back. The door was then locked in the right position to let him glide out into the cabin, where he adhered as quickly as possible to the carpet. He had long ago exhausted the novelty of weightlessness, and was grateful for the Velcro slippers that allowed him to walk almost normally.

  There was plenty to occupy his time, even if he did nothing but sit and read. When he tired of official reports and memoranda and minutes, he would plug his foolscap-sized Newspad into the ship's information circuit and scan the latest reports from Earth. One by one he would conjure up the world's major electronic papers; he knew the codes of the more important ones by heart, and had no need to consult the list on the back of his pad. Switching to the display unit's short-term memory, he would hold the front page while he quickly searched the headlines and noted the items that interested him. Each had its own two-digit reference; when he punched that, the postage-stamp-sized rectangle would expand until it neatly filled the screen and he could read it with comfort. When he had finished, he would flash back to the complete page and select a new subject for detailed examination.

  Floyd sometimes wondered if the Newspad, and the fantastic technology behind it, was the last word in man's quest for perfect communications. Here he was, far out in space, speeding away from Earth at thousands of miles an hour, yet in a few milliseconds he could see the headlines of any newspaper he pleased. (That very word "newspaper," of course, was an anachronistic hangover into the age of electronics.) The text was updated automatically on every hour; even if one read only the English versions, one could spend an entire lifetime doing nothing but absorbing the ever-changing flow of information from the news satellites.

  It was hard to imagine how the system could be improved or made more convenient. But sooner or later, Floyd guessed, it would pass away, to be replaced by something as unimaginable as the Newspad itself would have been to Caxton or Gutenberg.

  There was another thought which a scanning of those tiny electronic headlines often invoked. The more wonderful the means of communication, the more trivial, tawdry, or depressing its contents seemed to be. Accidents, crimes, natural and man-made disasters, threats of conflict, gloomy editorials—these still seemed to be the main concern of the millions of words being sprayed into the ether. Yet Floyd also wondered if this was altogether a bad thing; the newspapers of Utopia, he had long ago decided, would be terribly dull.

  From time to time the captain and the other members of the crew came into the cabin and exchanged a few words with him. They treated their distinguished passenger with awe, and were doubtless burning with curiosity about his mission, but were too polite to ask any questions or even to drop any hints.

  Only the charming little stewardess seemed completely at ease in his presence. As Floyd quickly discovered, she came from Bali, and had carried beyond the atmosphere some of the grace and mystery of that still largely unspoiled island. One of his strangest, and most enchanting, memories of the entire trip was her zero-gravity demonstration of some classical Balinese dance movements, with the lovely, blue-green crescent of the waning Earth as a backdrop.

  There was one sleep period, when the main cabin lights were switched off and Floyd fastened down his arms and legs with the elastic sheets that would prevent him from drifting away into space. It seemed a crude arrangement—but here in zero gravity his unpadded couch was more comfortable than the most luxurious mattress on Earth.

  When he had strapped himself in, Floyd dozed off quickly enough, but woke up once in a drowsy, half-conscious condition, to be completely baffled by his strange surroundings. For a moment he thought that be was in the middle of some dimly lit Chinese lantern; the faint glow from the other cubicles around him gave that impression. Then he said to himself, firmly and successfully: "Go to sleep, boy. This is just an ordinary moon shuttle."

  When he awoke, the Moon had swallowed up half the sky, and the braking maneuvers were about to begin. The wide arc of windows set in the curving wall of the passenger section now looked out onto the open sky, not the approaching globe, so he moved into the control cabin. Here, on the rear-view TV screen, he could watch the final stages of the descent.

  The approaching lunar mountains were utterly unlike those of Earth; they lacked the dazzling caps of snow, the green, close-fitting garments of vegetation, the moving crowns of cloud. Nevertheless, the fierce contrasts of light and shadow gave them a strange beauty of their own. The laws of earthly aesthetics did not apply here; this world had been shaped and molded by other than terrestrial forces, operating over eons of time unknown to the young, verdant Earth, with its fleeting Ice Ages, its swiftly rising and falling seas, its mountain ranges dissolving like mists before the dawn. Here was age inconceivable—but not death, for the Moon had never lived—until now.

  The descending ship was poised almost above the line dividing night from day, and directly below was a chaos of jagged shadows and brilliant, isolated peaks catching the first light of the slow lunar dawn. That would be a fearful place to attempt a landing, even with all possible electronic aids; but they were slowly drifting away from it, toward the night side of the Moon.

  Then Floyd saw, as his eyes grew more accustomed to the fainter illumination, that the night land was not wholly dark. It was aglow with a ghostly light, in which peaks and valleys and plains could be clearly seen. The Earth, a giant moon to the Moon, was flooding the land below with its radiance.

  On the pilot's panel, lights flashed above radar screens, numbers came and went on computer displays, clocking off the distance of the approaching Moon. They were still more than a thousand miles away when weight returned as the jets began their gentle but steady deceleration. For ages, it seemed, the Moon slowly expanded across the sky, the sun sank below the horizon, and at last a single giant crater filled the field of view. The shuttle was falling toward its central peaks—and suddenly Floyd noticed that near one of those peaks a brilliant light was flashing with a regular rhythm. It might have been an airport beacon back on Earth, and he stared at it with a tightening of the throat. It was proof that men had established another foothold on the Moon.

  Now the crater had expanded so much that its ramparts were slipping below the horizon, and the smaller craterlets that peppered its interior were beginning to disclose their real size. Some of these, tiny though they had seemed from far out in space, were miles across, and could have swallowed whole cities.

  Under its automatic controls, the shuttle was sliding down the starlit sky, toward that barren landscape glimmeri
ng in the light of the great gibbous Earth. Now a voice was calling somewhere above the whistle of the jets and the electronic beepings that came and went through the cabin.

  "Clavius Control to Special 14, you are coming in nicely. Please make manual check of landing-gear lock, hydraulic pressure, shock-pad inflation."

  The pilot pressed sundry switches, green lights flashed, and he called back, "All manual checks completed. Landing-gear lock, hydraulic pressure, shock pad O.K."

  "Confirmed," said the Moon, and the descent continued wordlessly. Though there was still plenty of talking, it was all being done by machines, flashing binary impulses to one another at a thousand times the rate their slow-thinking makers could communicate.

  Some of the mountain peaks were already towering above the shuttle; now the ground was only a few thousand feet away, and the beacon light was a brilliant star, flashing steadily above a group of low buildings and odd vehicles. In the final stage of the descent, the jets seemed to be playing some strange tune; they pulsed on and off, making the last fine adjustments to the thrust.

  Abruptly, a swirling cloud of dust hid everything, the jets gave one final spurt, and the shuttle rocked very slightly, like a rowboat when a small wave goes by. It was some minutes before Floyd could really accept the silence that now enfolded him and the weak gravity that gripped his limbs.

  He had made, utterly without incident and in little more than one day, the incredible journey of which men had dreamed for two thousand years. After a normal routine flight, he had landed on the Moon.

  Clavius Base

  Clavius, 150 miles in diameter, is the second largest crater on the visible face of the Moon, and lies in the center of the Southern Highlands. It is very old; ages of vulcanism and bombardment from space have scarred its walls and pockmarked its floor. But since the last era of crater formation, when the debris from the asteroid belt was still battering the inner planets, it had known peace for half a billion years.

  Now there were new, strange stirrings on and below its surface, for here Man was establishing his first permanent bridgehead on the Moon. Clavius Base could, in an emergency, be entirely self-supporting. All the necessities of life were produced from the local rocks, after they had been crushed, heated, and chemically processed. Hydrogen, oxygen, carbon, nitrogen, phosphorus—all these, and most of the other elements, could be found inside the Moon, if one knew where to look for them.

  The Base was a closed system, like a tiny working model of Earth itself, recycling all the chemicals of life. The atmosphere was purified in a vast "hothouse"—a large, circular room buried just below the lunar surface. Under blazing lamps by night, and filtered sunlight by day, acres of stubby green plants grew in a warm, moist atmosphere. They were special mutations, designed for the express purpose of replenishing the air with oxygen, and providing food as a by-product.

  More food was produced by chemical processing systems and algae culture. Although the green scum circulating through yards of transparent plastic tubes would scarcely have appealed to a gourmet, the biochemists could convert it into chops and steaks only an expert could distinguish from the real thing.

  The eleven hundred men and six hundred women who made up the personnel of the Base were all highly trained scientists or technicians, carefully selected before they had left Earth. Though lunar living was now virtually free from the hardships, disadvantages, and occasional dangers of the early days, it was still psychologically demanding, and not recommended for anyone suffering from claustrophobia. Since it was expensive and time-consuming to cut a large underground base out of solid rock or compacted lava, the standard one-man "living module" was a room only about six feet wide, ten feet long, and eight feet high.

  Each room was attractively furnished and looked very much like a good motel suite, with convertible sofa, TV, small hi-fi set, and vision-phone. Moreover, by a simple trick of interior decoration, the one unbroken wall could be converted by the flip of a switch into a convincing terrestrial landscape. There was a choice of eight views.

  This touch of luxury was typical of the Base, though it was sometimes hard to explain its necessity to the folk back on Earth. Every man and woman in Clavius had cost a hundred thousand dollars in training and transport and housing; it was worth a little extra to maintain their peace of mind. This was not art for art's sake, but art for the sake of sanity.

  One of the attractions of life in the base—and on the Moon as a whole—was undoubtedly the low gravity, which produced a sense of general well-being. However, this had its dangers, and it was several weeks before an emigrant from Earth could adapt to it. On the Moon, the human body had to learn a whole new set of reflexes. It had, for the first time, to distinguish between mass and weight.

  A man who weighed one hundred eighty pounds on Earth might be delighted to discover that he weighed only thirty pounds on the Moon. As long as he moved in a straight line at a uniform speed, he felt a wonderful sense of buoyancy. But as soon as he attempted to change course, to turn corners, or to stop suddenly—then he would find that his full one hundred eighty pounds of mass, or inertia, was still there. For that was fixed and unalterable—the same on Earth, Moon, Sun, or in free space. Before one could be properly adapted to lunar living, therefore, it was essential to learn that all objects were now six times as sluggish as their mere weight would suggest. It was a lesson usually driven home by numerous collisions and hard knocks, and old lunar hands kept their distance from newcomers until they were acclimatized.

  With its complex of workshops, offices, storerooms, computer center, generators, garage, kitchen, laboratories, and food-processing plant, Clavius Base was a miniature world in itself. And, ironically, many of the skills that had been used to build this underground empire had been developed during the half century of the Cold War.

  Any man who had ever worked in a hardened missile site would have felt at home in Clavius. Here on the Moon were the same arts and hardware of underground living, and of protection against a hostile environment; but here they had been turned to the purposes of peace. After ten thousand years, man had at last found something as exciting as war.

  Unfortunately, not all nations had yet realized that fact.

  The mountains that had been so prominent just before landing had mysteriously disappeared, hidden from sight below the steeply curving lunar horizon. Around the spacecraft was a flat, gray plain, brilliantly lit by the slanting earthlight. Although the sky was, of course, completely black, only the brighter stars and planets could be seen, unless the eyes were shaded from the surface glare.

  Several very odd vehicles were rolling up to the Aries-1B spaceship—cranes, hoists, servicing trucks—some automatic, some operated by a driver in a small pressure cabin. Most of them moved on balloon tires, for this smooth, level plain posed no transportation difficulties; but one tanker rolled on the peculiar flex-wheels which had proved one of the best all-purpose ways of getting around on the Moon. A series of flat plates arranged in a circle, each plate independently mounted and sprung, the flex-wheel had many of the advantages of the caterpillar track from which it had evolved. It would adapt its shape and diameter to the terrain over which it was moving, and, unlike a caterpillar track, would continue to function even if a few sections were missing.

  A small bus with an extension tube like a stubby elephant trunk was now nuzzling affectionately up against the spacecraft. A few seconds later, there were bangings and bumpings from outside, followed by the sound of hissing air as connections were made and pressure was equalized. The inner door of the airlock opened, and the welcoming delegation entered.

  It was led by Ralph Halvorsen, the Administrator of the Southern Province—which meant not only the Base but also any exploring parties that operated from it. With him was his Chief Scientist, Dr. Roy Michaels, a grizzled little geophysicist whom Floyd knew from previous visits, and half a dozen senior scientists and executives. They greeted him with respectful relief; from the Administrator
downward, it was obvious that they looked forward to a chance of unloading some of their worries.

  "Very pleased to have you with us, Dr. Floyd," said Halvorsen. "Did you have a good trip?"

  "Excellent," Floyd answered. "It couldn't have been better. The crew looked after me very well."

  He exchanged the usual small talk that courtesy demanded while the bus rolled away from the spacecraft; by unspoken agreement, no one mentioned the reason for his visit. After traveling a thousand feet from the landing site, the bus came to a large sign which read:

  WELCOME TO CLAVIUS BASE

  U.S. Astronautical Engineering Corps

  It then dived into a cutting which took it quickly below ground level. A massive door opened ahead, then closed behind them. This happened again, and yet a third time. When the last door had closed, there was a great roaring of air, and they were back in atmosphere once more, in the shirt-sleeve environment of the Base.

  After a short walk through a tunnel packed with pipes and cables, and echoing hollowly with rhythmic thumpings and throbbings, they arrived in executive territory, and Floyd found himself back in the familiar environment of typewriters, office computers, girl assistants, wall charts, and ringing telephones. As they paused outside the door labeled ADMINISTRATOR, Halvorsen said diplomatically: "Dr. Floyd and I will be along to the briefing room in a couple of minutes."

  The others nodded, made agreeable sounds, and drifted off down the corridor. But before Halvorsen could usher Floyd into his office, there was an interruption. The door opened, and a small figure hurled itself at the Administrator.
