Earthlight st-2

by Arthur Clarke

  The M.O. paused, and surveyed his quiet, intent audience. They were all taking it very well, but that was only to be expected. Every one was a trained man—they were the pick of the planets’ engineers and technicians.

  “As a matter of fact,” the surgeon continued cheerfully, “you’ll probably laugh when I tell you the biggest danger of the lot. It’s nothing more than sunburn. Out there you’ll be in the sun’s raw ultra-violet, unshielded by atmosphere. It can give you a nasty blister in thirty seconds, so we’ll make the crossing in the shadow of the Pegasus. If you happen to get outside that shadow, just shield your face with your arm. Those of you who’ve got gloves might as well wear them.

  “Well, that’s the picture. I’m going to cross with the first team just to show how easy it is. Now I want you to split up into four groups, and I’ll drill you each separately.”

  Side by side, the Pegasus and the Acheron raced toward the distant planet that only one of them would ever reach. The airlocks of the liner were open, gaping wide no more than a few meters from the hull of the crippled battleship. The space between the two vessels was strung with guide ropes, and among them floated the men of the liner’s crew, ready to give assistance if any of the escaping men were overcome during the brief but dangerous crossing.

  It was lucky for the crew of the Acheron that four pressure bulkheads were still intact. Their ship could still be divided into four separate compartments, so that a quarter of the crew could leave at a time. The airlocks of the Pegasus could not have held everyone at once if a mass escape had been necessary.

  Captain Halstead watched from the bridge as the signal was given. There was a sudden puff of smoke from the hull of the battleship, then the emergency hatch—certainly never designed for an emergency such as this—blew away into space. A cloud of dust and condensing vapor blasted out, obscuring the view for a second. He knew how the waiting men would feel the escaping air sucking at their bodies, trying to tear them away from their handholds.

  When the cloud had dispersed, the first men had already emerged. The leader was wearing a spacesuit, and all the others were strung on the three lines attached to him. Instantly, men from the Pegasus grabbed two of the lines and darted off to their respective airlocks. The men of the Acheron, Halstead was relieved to see, all appeared to be conscious and to be doing everything they could to help.

  It seemed ages before the last figure on its drifting line was towed or pushed into an airlock. Then the voice from one of those spacesuited figures out there shouted, “Close Number Three!” Number One followed almost at once; but there was an agonizing delay before the signal for Two came. Halstead could not see what was happening; presumably someone was still outside and holding up the rest. But at last all the locks were closed. There was no time to fill them in the normal way; the valves were jerked open by brute force and the chambers flooded with air from the ship.

  Aboard the Acheron, Commodore Brennan waited with his remaining ninety men, in the three compartments that were still unsealed. They had formed their groups and were strung in chains of ten behind their leaders. Everything had been planned and rehearsed; the next few seconds would prove whether or not in vain.

  Then the ship’s speakers announced, in an almost quietly conversational tone:

  “Pegasus to Acheron. We’ve got all your men out of the locks. No casualties. A few hemorrhages. Give us five minutes to get ready for the next batch.”

  They lost one man on the last transfer. He panicked and they had to slam the lock shut without him, rather than risk the lives of all the others. It seemed a pity that they could not all have made it, but for the moment everyone was too thankful to worry about that.

  There was only one thing still to be done. Commodore Bren-nan, the last man aboard the Acheron, adjusted the timing circuit that would start the drive in thirty seconds. That would give him long enough; even in his clumsy spacesuit he could get out of the open hatch in half that time. It was cutting it fine, but on!y he and his engineering officer knew how narrow the margin was.

  He threw the switch and dived for the hatch. He had already reached the Pegasus when the ship he had commanded, still loaded with millions of kilowatt-centuries of energy, came to life for the last time and dwindled silently toward the stars of the Milky Way.

  The explosion was easily visible among all the inner planets. It blew to nothingness the last ambitions of the Federation, and the last fears of Earth.

  Chapter XX

  Every evening, as the sun drops down beyond the lonely pyramid of Pico, the shadow of the great mountain reaches out to engulf the metal column that will stand in the Sea of Rains as long as the Sea itself endures. There are five hundred and twenty-seven names on that column, in alphabetical order. No mark distinguishes the men who died for the Federation from those who died for Earth, and perhaps this simple fact is the best proof that they did not die in vain.

  The Battle of Pico ended the domination of Earth and marked the coming of age of the planets. Earth was weary after her long saga and the efforts she had put forth to conquer the nearer worlds—those worlds which had now so inexplicably turned against her, as long ago the American colonies had turned against their motherland. In both cases the reasons were similar, and in both the eventual outcomes equally advantageous to mankind.

  Had either side won a clearcut victory, it might have been a disaster. The Federation might have been tempted to impose on Earth an agreement which it could never enforce. Earth, on the other hand, might well have crippled its errant children by withdrawing all supplies, thus setting back for centuries the colonization of the planets.

  Instead, it had been a stalemate. Each antagonist had learned a sharp and salutary lesson; above all, each had learned to respect the other. And each was now very busy explaining to its citizens exactly what it had been doing in their names…

  The last explosion of the war was followed, within a few hours, by political explosions on Earth, Mars and Venus. When the smoke had drifted away, many ambitious personalities had disappeared, at least for the time being, and those in power had one main objective—to re-establish friendly relations, and to erase the memory of an episode which did credit to no one.

  The Pegasus incident, cutting across the divisions of war and reminding men of their essential unity, made the task of the statesmen far easier than it might otherwise have been. The Treaty of Phobos was signed in what one historian called an atmosphere of shamefaced conciliation. Agreement was swift, for Earth and Federation each possessed something that the other needed badly.

  The superior science of the Federation had given it the secret of the accelerationless drive, as it is now universally but inaccurately called. For its part, Earth was now prepared to share the wealth she had tapped far down within the Moon. The barren crust had been penetrated, and at last the heavy core was yielding up its stubbornly guarded treasures. There was wealth here that would supply all man’s needs for centuries to come.

  It was destined, in the years ahead, to transform the solar system and to alter completely the distribution of the human race. Its immediate effect was to make the Moon, long the poor relation of the old and wealthy Earth, into the richest and most important of all the worlds. Within ten years, the Independent Lunar Republic would be dictating F.O.B. terms to Earth and Federation with equal impartiality.

  But the future would take care of itself. All that mattered now was that the war was over.

  Chapter XXI

  Central City, thought Sadler, had grown since he was here thirty years ago. Any one of these domes could cover the whole seven they had back in the old days. How long would it be, at this rate, before the whole Moon was covered up? He rather hoped it would not be in his time.

  The station itself was almost as large as one of the old domes. Where there had been five tracks, there were now thirty. But the design of the monocabs had not altered much, and their speed seemed to be about the same. The vehicle which had brought him from the spaceport might well ha
ve been the one that had carried him across the Sea of Rains a quarter of a lifetime ago.

  A quarter of a lifetime, that is, if you were a citizen of the Moon and could expect to see your one hundred and twentieth birthday. But a full third of a lifetime if you spent all your waking and sleeping hours fighting the gravity of Earth…

  There were far more vehicles in the streets; Central City was too big to operate on a pedestrian basis now. But one thing had not changed. Overhead was the blue, cloud-flecked sky of Earth, and Sadler did not doubt that the rain still came on schedule.

  He jumped into an autocab and dialed the address, relaxing as he was carried through the busy streets. His baggage had already gone to the hotel, and he was in no hurry to follow it. As soon as he arrived there, business would catch up with him again, and he might not have another chance of carrying out this mission.

  There seemed almost as many businessmen and tourists from Earth here as there were residents. It was easy to distinguish them, not only by their clothes and behavior but by the way they walked in this low gravity. Sadler was surprised to find that though he had been on the Moon only a few hours, the automatic muscular adjustment he had learned so long ago came smoothly into play again. It was like learning to ride a bicycle; once you had achieved it, you never forgot.

  So they had a lake here now, complete with islands and swans. He had read about the swans; their wings had to be carefully clipped to prevent their flying away and smashing into the “sky.” There was a sudden splash as a large fish broke the surface; Sadler wondered if it was surprised to find how high it could jump out of the water.

  The cab, threading its way above the buried guide-rods, swooped down a tunnel that must lead beneath the edge of the dome. Because the illusion of sky was so well contrived, it was not easy to tell when you were about to leave one dome and enter another, but Sadler knew where he was when the vehicle went past the great metal doors at the lowest part of the tube. These doors, so he had been told, could smash shut in less than two seconds, and would do so automatically if there was a pressure drop on either side. Did such thoughts as these, he wondered, ever give sleepless nights to the inhabitants of Central City? He very much doubted it; a considerable fraction of the human race had spent its life in the shadow of volcanoes, dams and dykes, without developing any signs of nervous tension. Only once had one of the domes of Central City been evacuated —in both senses of the word—and that was due to a slow leak that had taken hours to be effective.

  The cab rose out of the tunnel into the residential area, and Sadler was faced with a complete change of scenery. This was no dome encasing a small city; this was a single giant building in itself, with moving corridors instead of streets. The cab came to a halt, and reminded him in polite tones that it would wait thirty minutes for an extra one-fifty. Sadler, who thought it might take him that length of time even to find the place he was looking for, declined the offer and the cab pulled away in search of fresh customers.

  There was a large bulletin board a few meters away, displaying a three-dimensional map of the building. The whole place reminded Sadler of a type of beehive used many centuries ago, which he had once seen illustrated in an old encyclopedia. No doubt it was absurdly easy to find your way around when you’d got used to it, but for the moment he was quite baffled by Floors, Corridors. Zones and Sectors.

  “Going somewhere, mister?” said a small voice behind him.

  Sadler turned round, and saw a boy of six or seven years looking at him with alert, intelligent eyes. He was just about the same age as Jonathan Peter II. Lord, it had been a long time since he last visited the Moon…

  “Don’t often see Earth folk here,” said the youngster. “You lost?”

  “Not yet,” Sadler replied. “But I suspect I soon will be.”

  “Where going?”

  If there was a “you” in that sentence, Sadler missed it. It was really astonishing that, despite the interplanetary radio networks, distinct differences of speech were springing up on the various worlds. This boy could doubtless speak perfectly good Earth-English when he wanted to, but it was not his language of everyday communication.

  Sadler looked at the rather complex address in his notebook, and read it out slowly.

  “Come on,” said his self-appointed guide. Sadler gladly obeyed.

  The ramp ahead ended abruptly in a broad, slowly moving roller-road. This carried them forward a few meters, then decanted them on to a high-speed section. After sweeping at least a kilometer past the entrances to countless corridors, they were switched back on to a slow section and carried to a huge, hexagonal concourse. It was crowded with people, coming and going from one roadway to another, and pausing to make purchases at little kiosks. Rising through the center of the busy scene were two spiral ramps, one carrying the up and the other the down traffic. They stepped on to the “Up” spiral and let the moving surface lift them half a dozen floors. Standing at the edge of the ramp, Sadler could see that the building extended downward for an immense distance. A very long way below was something that looked like a large net. He did some mental calculations, then decided that it would, after all, be adequate to break the fall of anyone foolish enough to go over the edge. The architects of lunar buildings had a light-hearted approach to gravity which would lead to instant disaster on Earth.

  The upper concourse was exactly like the one by which they had entered, but there were fewer people about and one could tell that, however democratic the Autonomous Lunar Republic might be, there were subtle class distinctions here as in all other cultures that man had ever created. There was no more aristocracy of birth or wealth, but that of responsibility would always exist. Here, no doubt, lived the people who really ran the Moon. They had few more possessions, and a good many more worries, than their fellow citizens on the floors below, and there was a continual interchange from one level to another.

  Sadler’s small guide led him out of this central concourse along yet another moving passageway, then finally into a quiet corridor with a narrow strip of garden down its center and a fountain playing at either end. He marched up to one of the doors and announced: “Here’s place.” The brusqueness of his statement was quite neutralized by the proud there-wasn’t-that-clever-of-me smile he gave Sadler, who was now wondering what would be a suitable reward for his enterprise. Or would the boy be offended if he gave him anything?

  This social dilemma was solved for him by his observant guide.

  “More than ten floors, that’s fifteen.”

  So there’s a standard rate, thought Sadler. He handed over a quarter, and to his surprise was compelled to accept the change. He had not realized that the well-known lunar virtues of honesty, enterprise and fair-dealing started at such an early age.

  “Don’t go yet,” he said to his guide as he rang the doorbell. “If there’s no one in, I’ll want you to take me back.”

  “You not phoned first?” said that practical person, looking at him incredulously.

  Sadler felt it was useless to explain. The inefficiencies and vagaries of old-fashioned Earth-folk were not appreciated by these energetic colonists—though heaven help him if he ever used that word here.

  However, there was no need for the precaution. The man he wanted to meet was at home, and Sadler’s guide waved him a cheerful good-by as he went off down the corridor, whistling a tune that had just arrived from Mars.

  “I wonder if you remember me,” said Sadler. “I was at the Plato Observatory during the Battle of Pico. My name’s Bertram Sadler.”

  “Sadler? Sadler? Sorry, but I don’t remember you at the moment. But come right in; I’m always pleased to meet old friends.”

  Sadler followed into the house, looking round curiously as he did so. It was the first time he had ever been into a private home on the Moon, and as he might have expected there was no way in which it could be distinguished from a similar residence on Earth. That it was one cell in a vast honeycomb did not make it any less a home; it had been two centuri
es since more than a minute fraction of the human race had lived in separate, isolated buildings and the word “house” had changed its meaning with the times.

  There was just one touch in the main living room, however, that was too old-fashioned for any terrestrial family. Extending halfway across one wall was a large animated mural of a kind which Sadler had not seen for years. It showed a snow-flecked mountainside sloping down to a tiny Alpine village a kilometer or more below. Despite the apparent distance, every detail was crystal clear; the little houses and the toy church had the sharp, vivid distinctness of something seen through the wrong end of a telescope. Beyond the village, the ground rose again, more and more steeply, to the great mountain that dominated the skyline and trailed from its summit a perpetual plume of snow, a white streamer drifting forever down the wind.

  It was, Sadler guessed, a real scene recorded a couple of centuries ago. But he could not be sure; Earth still had such surprises in out-of-the-way spots.

  He took the seat he was offered and had his first good look at the man he had played truant from rather important business to meet. “You don’t remember me?” he said.

  “I’m afraid not—but I’m quite bad at names and faces.”

  “Well, I’m nearly twice as old now, so it’s not surprising. But you haven’t changed, Professor Molton. I can still remember that you were the first man I ever spoke to on my way to the Observatory. I was riding the monorail from Central City, watching the sun going down behind the Apennines. It was the night before the Battle of Pico, and my first visit to the Moon.”

  Sadler could see that Molton was genuinely baffled. It was thirty years, after all, and he must not forget that he had a completely abnormal memory for faces and facts.

  “Never mind,” he continued. “I couldn’t really expect you to remember me, because I wasn’t one of your colleagues. I was only a visitor to the Observatory, and I wasn’t there long. I’m an accountant, not an astronomer.”
