Fourth Printing Chapter I "Look—there—rising over the Hand of God. Is it?" "Yes, I think so. Our ship." They were the last to go as Millesgarden was closed. Most of that afternoon they had wandered among the sculptures, he awed and delighted by his first experience of them, she bidding an unspoken farewell to what had been more a part of her life than she had understood until now. They were lucky in the weather, when summer was waning. This day on Earth had been sunlight, breezes that made leaf shadows dance on the villa walls, a clear sound of fountains. But when the sun went down, the garden seemed abruptly to come still more alive. It was as if the dolphins were tumbling through their waters, Pegasus storming skyward, Folke Filbyter peering after his lost grandson while his horse stumbled in the ford, Orpheus listening, the young sisters embracing in their resurrection—all unheard, because this was a single instant perceived, but the time in which these figures actually moved was no less real than the time which carried men. "As if they were alive, bound for the stars, and we must stay behind and grow old," Ingrid Lindgren murmured. Charles Reymont didn't hear her. He stood on the flag­stones under a birch tree, whose leaves rustled and had begun very faintly to turn color, and looked toward Leonora Chris­tine. Atop its pillar, the Hand of God upbearing the Genius of Man lifted in silhouette against a greenish-blue dusk. Behind it, the tiny rapid star crossed and sank again. "Are you sure that wasn't an ordinary satellite?" Lindgren asked through quietness. "I never expected we'd see—" Reymont cocked a brow at her. "You're the first officer, and you don't know where your own vessel is or what she's 1 doing?" His Swedish had a choppy accent, like most of the languages he spoke, that underlined the sardonicism. "I'm not the navigation officer," she said, defensive. "Also, I put the whole matter out of my mind as much as I can. You should do the same. We'll spend plenty of years with it." She half reached toward him. Her tone gentled. "Please. Don't spoil this evening." Reymont shrugged. "Pardon me. I didn't mean to." An attendant neared, stopped, and said deferentially: "I am sorry, we must shut the gates now." "Oh!" Lindgren started, glanced at her watch, looked over the terraces. They were empty of everything except the life that Carl Milles had shaped into stone and metal, three centuries ago. "Why, why, it's far past closing time. I hadn't realized." The attendant bowed. "Since my lady and gentleman obviously wished it, I let them alone after the other visitors left." "You know us, then," Lindgren said. "Who does not?" The attendant's gaze admired her. She was tall and well formed, regular of features, blue eyes set wide, blond hair bobbed just under the ears. Her civilian garments were more stylish than was common on a spacewo-man; the rich soft colors and flowing draperies of neomedieval suited her. Reymont contrasted. He was a stocky, dark, hard-countenanced man who had never bothered to have removed the scar that seamed his brow. His plain tunic and trews might as well have been a uniform. "Thank you for not pestering us," he said, more curt than cordial. "I took for granted you wished freedom from being a celebrity," the attendant replied. "No doubt many others recognized you too but felt likewise." "You'll find we Swedes are a courteous people." Lindgren smiled at Reymont. "I won't argue that," her companion said. "Nobody can help running into it, when you're everywhere in the Solar System." He paused. "But then, whoever steers the world 2 had better be polite. The Romans were in their day. Pilate, for instance." The attendant was taken aback at the implied rebuff. Lindgren declared a little sharply, "I said dlskvdrdig, not artig. " ("Courteous," not "polite.") She offered her hand. "Thank you, sir." "My pleasure, Miss First Officer Lindgren," the atten­dant answered. "May you have a fortunate voyage and come home safe." "If the voyage is really fortunate," she reminded him, "we will never come home. If we do—" She broke off. He would be in his grave. "Again I thank you," she said to the little middle-aged man. "Good-by,'' she said to the gardens. Reymont exchanged a clasp too and mumbled something. He and Lindgren went out. High walls darkened the nearly deserted pavement beyond. Footfalls sounded hollow. After a minute the woman remarked, "I do wonder if that was our ship we saw. We're in a high latitude. And not even a Bussard vessel is big and bright enough to shine through sunset glow." "She is when the scoopfield webs are extended," Rey­mont told her. "And she was moved into a skewed orbit yesterday, as part of her final tests. They'll take her back to the ecliptic plane before we depart." "Yes, of course, Fve seen the program. But Fve no reason to remember exactly who is doing what with her at which time. Especially when we aren't leaving for another two months. Why should you keep track?" ' 'When I'm simply the constable.'' Reymont's mouth bent into a grin. "Let's say that I'm practicing to be a wor­ry wart." She glanced sideways at him. The look became a scrutiny. They had emerged on an esplanade by the water. Across it, Stockholm's lights were kindling, one by one, as night grew upward among houses and trees. But the channel remained almost mirrorlike, and as yet there were few sparks in heaven save Jupiter. You could still see without help. Reymont hunkered down and drew their hired boat in. Bond anchors secured the lines to the concrete. He had 3 obtained a special license to park practically anywhere. An interstellar expedition was that big an event. Lindgren and he had spent the morning in a cruise around the Archipelago—a few hours amidst greenness, homes like parts of the islands whereon they grew, sails and gulls and sun-glitter across waves. Little of that would exist at Beta Virginis, and none of it in the distances between. "I am beginning to feel what a stranger you are to me, Carl," she said slowly. "To everyone?" "Eh? My biography's on record." The boat bumped against the esplanade. Reymont sprang down into its cockpit. Holding the line taut with one hand, he offered her the other. She had no need to lean heavily on him as she descended, but did. His arm scarcely stirred beneath her weight. She sat down on a bench next the wheel. He twisted the screw top of the anchor he grasped. Intermolecular binding forces let go with a faint smacking noise that answered the slap-slap of water on hull. His movements could not be called graceful, as hers were, but they were quick and economical. "Yes, I suppose we've all memorized each other's official accounts." She nodded. "For you, the absolute minimum you could get by with telling." (Charles Jan Reymont. Citizenship status, Interplaneta-rian. Thirty-five years old. Born in the Antarctic, but not one of its better colonies; the sublevels of Polyugorsk offered only poverty and turbulence to a boy whose father had died early. The youth he became got to Mars by some unspecified means and held a variety of jobs till the troubles broke out. Then he fought with the Zebras, with such distinction that afterward the Lunar Rescue Corps offered him a berth. There he completed his academic education and rose fast in rank, until as colonel he had much to do with improving the police branch. When he applied for this expedition, the Control Authority was glad to accept him.) "Nothing whatsoever of yourself," Lindgren observed. ' 'Did you even give that away in the psychological testing?" Reymont had gone forward and cast off the bow line. He stowed both anchors neatly, took the wheel, and started the motor. The magnetic drive was soundless and the propeller made scant noise, but the boat slipped rapidly outward. He 4 kept his eyes straight ahead. "Why do you care?" he asked. 4'We'll be together for a number of years. Quite possibly for the rest of our lives." "It makes me wonder why you spent today with me, then." "You invited me." "After you gave me a call at my hotel. You must have checked with the crew registry to find where I was." Millesgarden vanished in swift-deepening darkness aft. Lights along the channel, and from the inner city beyond, did not show whether she flushed. Her face turned from him, though. "I did, "she admitted. "I ... thought you might be lonely. You have no one, have you?" "No relatives left. I'm only touring the fleshpots of Earth. Won't be any where we are bound." Her sight lifted again, toward Jupiter this time, a steady tawny-white lamp. More stars were treading forth. She shiv­ered and drew her cloak tight around her, against the autum­nal air. "No," she said mutedly. "Everything alien. And when we've hardly begun to map, to understand, that world yonder—our neighbor, our sister—to cross thirty-two light-years—'' "People are like that." "Why are you going, Carl?" His shoulders lifted and dropped. "Restless, I suppose. And frankly, I made enemies in the Corps. Rubbed them the wrong way, or outdistanced them for promotion. I was at the point where I couldn't advance further without playing office politics. Which I despise." His glance met hers. Both lin­gered a moment. "You?" She sighed. "Probably sheer romanticism. Ever since I was a child, I thought I must go to the stars, the way a prince in a fairy tale must go to Elf Land. At last, by insisting to my parents, I got them to let me enroll in the Academy." His smile held more warmth than usual. "And you made an outstanding record in the interplanetary service. They didn't hesitate to make you first officer of your first extrasolar ship." Her hands fluttered in her lap. "No. Please. I'm not bad at my work. But it's easy for a woman to rise fast in space. 5 She's in demand. And my job on Leonora Christine will be essentially executive. I'll have more to do with . . . well, human relations . . . than astronautics." He returned his vision forward. The boat was rounding the land, headed into Saltsjon. Water traffic thickened. Hy­drofoils whirred past. A cargo submarine made her stately way toward the Baltic. Overhead, air taxis flitted like fire­flies. Central Stockholm was a many-colored unrestful fire and a thousand noises blent into one somehow harmonious growl. 4'That brings me back to my question." Reymont chuc­kled. *'My counter-question, rather, since you were pressing in on me. Don't think I haven't enjoyed your company. I did, much, and if you'll have dinner with me I'll consider this day among the better ones of my life. But most of our gang scattered like drops of mercury the minute our training period ended. They're deliberately avoiding their shipmates. Better spend the time with those they'll never see again. You, now—you have roots. An old, distinguished, well-to-do family; an affectionate one, I gather; father and mother alive, brothers, sisters, cousins, surely anxious to do everything they can for you in the few weeks that remain. Why did you leave them today?" She sat unspeaking. "Your Swedish reserve," he said after awhile. "Appro­priate to the rulers of mankind. I ought not to have intruded. Just give me the same right of privacy, will you?" And presently: "Would you like to join me at dinner? I've found quite a decent little live-service restaurant." "Yes," she answered. "Thank you. I would." She rose to stand beside him, laying one hand on his arm. The thick muscles stirred beneath her fingers. "Don't call us rulers," she begged. "We aren't. That's what the whole idea was behind the Covenant. After the nuclear war . . . that close a brush with world death . . . something had to be done." "Uh-huh," he grunted. "I've read an occasional history book myself. General disarmament; a world police force to maintain it; sed quis custodiet ipsos Custodes? Who can we trust with a monopoly of the planet killer weapons and un­limited powers of inspection and arrest? Why, a country 6 big and modern enough to make peace-keeping a major industry; but not big enough to conquer anyone else or force its will on anyone without the support of a majority of nations; and reasonably well thought of by everyone. In short, Sweden." "You do understand, then," she said happily. "I do. Including the consequences. Power feeds on itself, not by conspiracy, but by logical necessity. The money the world pays, to underwrite the cost of the Control Authority, passes through here; therefore you become the richest coun­try on Earth, with all that that implies. And the diplomatic center, goes without saying. And when every reactor, space­ship, laboratory is potentially dangerous and must be under the Authority, that means some Swede has a voice in every­thing that matters. And this leads to your being imitated, even by those who no longer like you. Ingrid, my friend, your people can't help turning into new Romans." Her gladness drooped. "Don't you like us, Carl?" "As well as anybody, considering. You've been humane masters to date. Too humane, I'd say. In my own case, I ought to be grateful, since you allow me to be essentially a stateless person, which I think I prefer. No, you've not done badly." He gestured toward the towers down which radiance cataracted, to right and left. "It won't last, anyhow." "What do you mean?" "I don't know. I'm only certain that nothing is forever. No matter how carefully you design a system, it will go bad and die." Reymont stopped to choose words. "In your case," he said, "I believe the end may come from this very stability you take pride in. Has anythinjg important changed, on Earth at least, since the late twentieth century? Is that a desirable state of affairs? "I suppose," he added, "that's one reason for planting colonies in the galaxy, if we can. Against Ragnarok." Her fists clenched. Her face turned upward again. The night was now entire, but few stars could be seen through the veil of light over the city. Elsewhere—in Lapland, for in­stance , where her parents had a summer cottage—they would shine unmercifully sharp and many. "I'm being a poor escort," Reymont apologized. "Let's 7 get off these schoolboy profundities and discuss more inter­esting subjects. Like an aperitif." Her laugh was uncertain. He managed to keep the talk inconsequential while he nosed into Strommen, docked the boat, and led her on foot across the bridge to Old Town. Beyond the royal palace they found themselves under softer illumination, walking down narrow streets between high golden-hued buildings that had stood much as they were for several hundred years. Tourist season was past; of the uncounted foreigners in the city, few had reason to visit this enclave; except for an occasional pedestrian or electrocyclist, Reymont and Lindgren were nearly alone. "I shall miss this," she said. "It's picturesque," he conceded. "More than that, Carl. It's not just an outdoor museum. Real human beings live here. And the ones who were before them, they stay real too. In, oh, Birger Jarl's Tower, the Riddarholm Church, the shields in the House of Nobles, the Golden Peace where Bellman drank and sang— It's going to be lonely in space, Carl, so far from our dead." . "Nevertheless you're leaving." "Yes. Not easily. My mother who bore me, my father who took me by the hand and led me out to teach me constella­tions. Did he know what he was doing to me that night?" She drew a breath. "That's partly why I got in touch with you. I had to escape from what I'm doing to them. If only for a single day." "You need a drink," he said, "and here we are." The restaurant fronted on the Great Marketplace. Between the surrounding steep facades you could imagine how knights had clattered merrily across the paving stones. You did not remember how the gutters ran with blood and heads were stacked high during a certain winter week, for that was long past and men seldom dwell on the hurts that befell other men. Reymont conducted Lindgren to a table in a candlelit room which they had to themselves, and ordered akyavit with beer chasers. She matched him drink for drink, though she had less mass 8 and less practice. The meal that followed was lengthy even by Scandinavian standards, with considerable wine during it and considerable cognac afterward. He let her do most of the talking —of i house near Drottningholm, whose park and gardens were almost her own; sunlight through windows, gleaming over burnished wood floors and on silver that had been passed down for ten generations; a sloop on the lake, heeled to the wind, her father at the tiller with a pipe in his teeth, her hair blowing loose; monstrous nights at wintertime, and in their middle that warm cave named Christmas; the short light nights of summer, the balefires kindled on St. John's Eve that had once been lit to welcome Baldr home from the under­world; a walk in the rain with a first sweetheart, the air cool, drenched with water and odor of lilacs; travels around Earth, the Pyramids, the Parthenon, Paris at sunset from the top of Montparnasse, the Taj Mahal, Angkor Wat, the Kremlin, the Golden Gate Bridge, yes, and Fujiyama, the Grand Canyon, Victoria Falls, the Great Barrier Reef— —of love and merriment at home but discipline too, order, gravity in the presence of strangers; music around, Mozart the dearest; a fine school, where teachers and classmates brought a complete new universe exploding into her aware­ness; the Academy, harder work than she had known she could do, and how pleased she was to discover she was able; cruises through space, to the planets, oh, she had stood on the snows of Titan with Saturn overhead, stunned by beauty; always, always her kindred to return to— —in a good world, its people, their doings, their pleasures all good; yes, there remained problems, outright cruelties, but those could be solved in time through reason and good will; it would be a joy to believe in some kind of religion, since that would perfect the world by giving it ultimate purpose, but in the absence of convincing proof she could still do her best to help supply that meaning, help mankind move toward something loftier— —but no, she wasn't a prig, he mustn't believe that; in fact, she often wondered if she wasn't too hedonistic, a bit more liberated than was best; however, she did get fun out of 9 life without hurting anyone else, as far as she could tell; she lived with high hopes. Reymont poured the last coffee for her. The waiter had finally brought the bill, though he seemed in no more hurry to collect than most of his kind in Stockholm. "I except that in spite of the drawbacks," Reymont said, "you'll manage to enjoy our voyage." Her voice had gotten a bit slurred. Her eyes, regarding him, stayed bright and level. "I plan to," she declared. "That's the main reason I called you. Remember, during training I urged you to come here for part of your furlough/' By now they were using the intimate pronoun. Reymont drew on his cigar. Smoking would be prohibited in space, to avoid overloading the life support systems, but tonight he could still put a blue cloud in front of him. She leaned forward, laying a hand over his free one on the table. "I was thinking ahead," she told him. "Twenty-five men and twenty-five women. Five years in a metal shell. Another five years if we turn back immediately. Even with antisenescence treatments, a decade is a big piece out of a life." He nodded. "And of course we'll stay to explore," she went on. "If that third planet is habitable, we'll stay to colonize— forever—and we'll start having children. Whatever we do, there are going to be liaisons. We'll pair off." He said, low lest it seem too blunt: "You think you and I might make a couple?" "Yes." Her tone strengthened. "It may seem immodest of me, whether or not I am a spacewoman. But I'll be busier than most, the first several weeks of travel especially. I won't have time for nuances and rituals. It could end with me in a situation I don't want. Unless I think ahead and make prepa­rations. As I'm doing." He lifted her hand to his lips. "I am deeply honored, Ingrid. Though we may be too unlike." "No, I suspect that's what draws me." Her palm curved around his mouth and slid down his cheek. "I want to know you. You are more a man than any I've met before." 10 He counted money onto the bill. It was the first time that she had seen him move not entirely steadily. He ground out his cigar, watching it as he did. "Im staying at a hotel over on Tyska Brinken," he said. "Rather shabby." "I don't mind," she answered. "I doubt if I'll notice." 11 Chapter 2 Seen from one of the shuttles that brought her crew to her, Leonora Christine resembled a dagger pointed at the stars. Her hull was a conoid, tapering toward the bow. Its bur­nished smoothness seemed ornamented rather than broken by the exterior fittings. These were locks and hatches; sensors for instruments; housings for the two boats that would make the planetf alls for which she herself was not designed; and the web of the Bussard drive, now folded flat. The base of the conoid was quite broad, since it contained the reaction mass among other things; but the length was too great for this to be particularly noticeable. At the top of the dagger blade, a structure fanned out which you might have imagined to be the guard of a basket hilt. Its rim supported eight skeletal cylinders pointing aft. These were the thrust tubes, that accelerated the reaction mass backward when the ship moved at merely interplanetary speeds. The ''basket" enclosed their controls and power plant. Beyond this, darker in hue, extended the haft of the dag­ger, ending finally in an intricate pommel. The latter was the Bussard engine; the rest was shielding against its radiation when it should be activated. Thus Leonora Christine, seventh, and youngest of her class. Her outward simplicity was required by the nature of her mission and was as deceptive as a human skin; inside, she was very nearly as complex and subtle. The time since the basic idea of her was first conceived, in the middle twentieth century, had included perhaps a million man-years of thought and work directed toward achieving the reality; and some of those men had possessed intellects equal to any that had ever existed. Though practical experience and essential tools had already been gotten when construction was begun upon her, and though technological civilization had reached its fantas- 12 tic flowering (and finally, for a while, was not burdened by war or the threat of war)—nevertheless, her cost was by no means negligible, had indeed provoked widespread com­plaint. All this, to send fifty people to one practically next-door star? Right. That's the size of the universe. It loomed behind her, around her, where she circled Earth. Staring away from sun and planet, you saw a crystal darkness huger than you dared comprehend. It did not appear totally black; there were light reflections within your eyeballs, if nowhere else; but it was the final night, that our kindly sky holds from us. The stars thronged it, unwinking, their bril­liance winter-cold. Those sufficiently luminous to be seen from the ground showed their colors clear in space: steel-blue Vega, golden Capella, ember of Betelgeuse. And if you were not trained, the lesser members of the galaxy that had become visible were so many as to drown the familiar constellations. The night was wild with suns. And the Milky Way belted heaven with ice and silver; and the Magellanic Clouds were not vague shimmers but roiling and glowing; and the Andromeda galaxy gleamed sharp across more than a million light-years; and you felt your soul drowning in those depths and hastily pulled your vision back to the snug cabin that held you. Ingrid Lindgren entered the bridge, caught a handhold, and poised in mid-air. "Reporting for duty, Mr. Captain," she announced formally. Lars Telander turned about to greet her. In free fall, his gaunt and gawky figure became lovely to watch, like a fish in water or a hawk on the wing. Otherwise he could have been any gray-haired man of fifty-odd. Neither of them had bothered to put insignia of rank on the coveralls that were standard shipboard working attire. "Good day,'' he said. ''I trust you had a pleasant leave.'' ' 'I certainly did." The color mounted in her cheeks. "And you?" "Oh ... it was all right. Mostly I played tourist, from end to end of Earth. I was surprised at how much I had not seen before." 13 Lindgren regarded him with some compassion. He floated alone by his command seat, one of three clustered around a control and communications console at the middle of the circular room. The meters, readout screens, indicators, and other gear that crowded the bulkheads, already blinking and quivering and tracing out scrawls, only emphasized his isola­tion. Until she came, he had not been listening to anything except the murmur of ventilators or the infrequent click of a relay. I i' You have nobody whatsoever left?" she asked. 'Nobody close." Telander's long features crinkled in a smile. "Don't forget, as far as the Solar System is concerned, I have almosteounted a century. When last I visited my home village in Dalarna, my brother's grandson was the proud father of two adolescents. It was not to be expected that they would consider me a near relative." (He was born three years before the first manned expedi­tion departed for Alpha Centauri. He entered kindergarten two years before the first maser messages from it reached Farside Station on Luna. That set the life of an introverted, idealistic child on trajectory. At age twenty-five, an Academy graduate with a notable performance in the inter­planetary ships, he was allowed on the first crew for Epsilon Eridani. They returned twenty-nine years later; but because of the time dilation, they had experienced just eleven, includ­ing the six spent at the goal planets. The discoveries they had made covered them with glory. The Tau Ceti ship was outfit­ting when they came back. Telander could be the first officer if he was willing to leave in less than a year. He was. Thirteen years of his own went by before he returned, commander in place of a captain who had died on a world of peculiar savageries. On Earth, the interval had been thirty-one years. Leonora Christine was being assembled in orbit. Who better than him for her master? He hesitated. She was to start in barely three years. If he accepted, most of those thousand days would be spent planning and preparing. . . . But not to accept was probably not thinkable; and too, he walked as a stranger on an Earth grown strange to him.) "Let's get busy," he said. "I assume Boris Fedoroff and his engineers rode up with you?" 14 She nodded. "You'll hear him on the intercom after he's organized, he told me." "Hm. He might have observed the courtesy of notifying me of his arrival." "He's in a foul mood. Sulked the whole way from ground. I don't know why. Does it matter?" "We are going to be together in this hull for quite a while, Ingrid," Telander remarked. "Our behavior will indeed matter." "Oh, Boris will get over his fit. I suppose he has a hangover, or some girl said no to him last night, or some­thing. He struck me during training as a rather soft-hearted person." "The psychoprofile indicates it. Still, there are things— potentialities—in each of us that no testing shows. You have to be yonder—" Telander gestured at the hood of the optical periscope, as if it were the remoteness that it watched— "before those develop, for good or bad. And they do. They always do." He cleared his throat. "Well. The scientific personnel are on schedule also?" "Yes. They'll arrive in two ferries, first at 1340 hours, second at 1500.'' Telander noted agreement with the program clamped to the desk part of the console. Lindgren added: "I don't believe we need that much interval between them." "Safety margin," Telander replied absently. "Besides, training or no, we'll need time to get that many groundlub-bers to their berths, when they can't handle themselves properly in weightlessness." "Carl can handle them," Lindgren said. "If need be, he can carry them individually, faster than you'd credit till you saw him." "Reymont? Our constable?" Telander studied her flutter­ing lashes.' 'I know he's skilled in free fall, and he'll come on the first ferry, but is he that good?" "We visited L'Etoile de Plaisir." "Where?" "A resort satellite." "Hm, yes, that one. And you played null-gee games?" Lindgren nodded, not looking at the captain. He smiled again. "Among other things, no doubt." 15 "He'll be staying with me." "Um-m-m. . . ." Telander rubbed his chin. "To be honest, I'd rather have him in the cabin already agreed on, in case of trouble among the, urn, passengers. That's what he's for, en route." "I could join him,"'Lindgren offered. Telander shook his head. "No. Officers must live in officer country. The theoretical reason, having them next to bridge level, isn't the real one. You'll find out how important symbols are, Ingrid, in the next five years." He shrugged. "Well, the other cabins are only one deck abaft ours. I daresay he can get to them soon enough if need be. Assuming your arranged roommate doesn't mind a swap, have your wish, then." "Thank you," she said low. "I can't help being a little surprised,'' Telander confessed. "He doesn't appear to me as the sort you'd choose. Do you think the relationship will last?" ' 'I hope it will. He says he wants it to." She broke from her confusion with a teasing attack: "What about you? Have you made any commitments yet?" "No. In time, doubtless, in time. I'll be too busy at first. At my age these matters aren't that urgent." Telander laughed, then grew earnest. "A propos time, we've none to waste. Please carry out your inspections and—" The ferry made rendezvous and docked. Bond anchors extended to hold its stubby hull against the larger curve of Leonora Christine. Her robots—sensor-computer-effector units—directing the terminal maneuvers caused airlocks to join in an exact kiss. More than that would be demanded of them later. Both chambers being exhausted, their outer valves swung back, enabling a plastic tube to make an airtight seal. The locks were repressurized and checked for a possible leak. When none was found, the inner valves opened. Reymont unharnessed himself. Floating free of his seat, he glanced down the length of the passenger section. The American chemist, Norbert Williams, was unbuckling too. "Hold it," Reymont commanded in English. While everyone knew Swedish, some did not know it well. For 16 scientists, English and Russian remained the chief interna­tional tongues. "Keep your places. I told you at the port, I'll escort you singly to your cabins." "You needn't bother with me," Williams answered. "I can get around weightless okay." He was short, round-faced, sandy-haired, given to colorful garments and to speak­ing rather loudly. "You all had some drill in it," Reymont said. "But that's not the same thing as getting the right reflexes built in through experience." "So we flounder a bit. So what?" "So an accident is possible. Not probable, I agree, but possible. My duty is to help forestall such possibilities. My judgment is that I should conduct you to your berths, where you will remain until further notice." Williams reddened, "See here, Reymont—" The constable's eyes, which were gray, turned full upon him. "That's a direct order," Reymont said, word by word. "I have the authority. Let us not begin this voyage with a breach." Williams resecured himself. His motions were needlessly energetic, his lips clamped tight together. A few drops of sweat broke off his forehead and bobbed in the aisles; the overhead fluoro made them sparkle. Reymont spoke by intercom to the pilot. That man would not board the ship, but would boost off as soon as his human cargo was discharged. "Do you mind if we unshutter? Give our friends something to look at while they wait?" "Go ahead," said the voice. "No hazard indicated. And . . . they won't see Earth again for a spell, will they?" Reymont announced the permission. Hands eagerly turned cranks on the spaceward side of the boat, sliding back the plates that covered the glasyl viewpoints. Reymont got busy with his shepherding. Fourth in line was Chi-Yuen Ai-Ling. She had twisted about in her safety webbing to face the port entirely. Her fingers were pressed against its surface. "Now you, please,'' Reymont said. She didn't respond. "Miss Chi-Yuen." He tapped her shoulder. "You're next." "Oh!" She might have been shaken out of a dream. Tears 17 stood in her eyes. "I, I beg your pardon. I was lost—" The linked spacecraft were coming into another dawn. Light soared over Earth's immense horizon, breaking in a thousand colors from maple-leaf scarlet to peacock blue. Momentarily a wing of zodiacal radiance could be seen, like a halo over the rising fire-disk. Beyond were the stars and a crescent moon. Below was the planet, agleam with her oceans, her clouds where rain and thunder walked, her green-brown-snowy continents and jewel-box cities. You saw, you felt, that this world lived. Chi-Yuen fumbled with her buckles. Her hands looked too thin for them. "I hate to stop watching," she whispered in French. "Rest well there, Jacques." "You'll be free to observe on the ship screens, once we've commenced acceleration," Reymont told her in the same language. The fact that he spoke it startled her back to ordinariness. "Then we will be going away," she said, but with a smile. Her mood had evidently been more ecstatic than elegiac. She was small, frail-boned, her figure seeming a boy's in the high-collared tunic and wide-cut slacks of the newest Oriental mode. Men tended to agree, however, that she had the most enchanting face aboard, coifed in shoulder-length blue-black hair. When she spoke Swedish, the trace of Chinese intonation that she gave its natural lilt made it a song. Reymont helped her unstrap and laid an arm around her waist. He didn't bother with shuffling along in bondsole shoes. Instead, he pushed one foot against the chair and flew down the aisle. At the lock he seized a handhold, swung through an arc, gave himself a fresh shove, and was inside the starship. In general, those whom he escorted relaxed; it was easier for him to carry them passive than to contend with their clumsy efforts to help. But Chi-Yuen was different. She knew how. Their movements turned into a swift, swooping dance. After all, as a planetologist she had had a good deal of experience with free fall. Their flight was not less exhilarating for being explainable. The companionway from the airlock ran through concen­tric layers of storage decks: extra shielding and armor for the cylinder at the axis of the ship which housed personnel. Elevators could be operated there, to carry heavy loads for- 18 ward or aft under acceleration. But probably the stairs which spiraled through wells parallel to the elevator shafts would see more use. Reymont and Chi-Yuen took one of these to get from the center-of-mass deck devoted to electrical and gyro­scopic machinery, bow-ward to the living quarters. Weight­less, they hauled themselves along the stair rail never touch­ing a step. At the speed they acquired, centrifugal and Coriolis forces made them somewhat dizzy, like a mild drunkenness bringing forth laughter. "And ay-round we go ay-gain . . . wheel" The cabins for those other than officers opened on two corridors which flanked a row of bathrooms. Each compart­ment was two meters high and four square; it had two doors, two closets, two built-in dressers with shelves above, and two folding beds. These last could be slid together on tracks to form one, or be pushed apart. In the second case, it then became possible to lower a screen from the overhead and thus turn the double room into two singles. "That was a trip to write about in my diary, Constable." Chi-Yuen clutched a handhold and leaned her forehead against the cool metal. Mirth still trembled on her mouth. "Who are you sharing this with?" Reymont asked. ' * For the present, Jane Sadler.'' Chi-Yuen opened her eyes and let them glint at him. "Unless you have a different idea?" "Heh? Uh ... I'm with Ingrid Lindgren." 'Already?" The mood dropped from her. "Forgive me. I should not pry." "No, I'm the one who owes the apology," he said. 4 'Making you wait here with nothing to do, as if you couldn't manage in free fall." "You can't make exceptions." Chi-Yuen was altogether serious again. She extended her bed, floated onto it, and started harnessing in. "I want to lie awhile alone any Way and think." "About Earth?" "About many things. We are leaving more than most of us have yet understood, Charles Reymont. It is a kind of death —followed by resurrection, perhaps, but nonetheless a death." 19 Chapter 3 "—zero!" The ion drive came to life. No man could have gone behind its thick shielding to watch it and survived. Nor could he listen to it, or feel any vibration of its power. It was too efficient for that. In the so-called engine room, which was actually an electronic nerve center, men did hear the faint throb of pumps feeding reaction mass from the tanks. They hardly noticed, being intent on the meters, displays, read­outs, and code signals which monitored the system. Boris Fedoroff s hand was never distant from the primary cutoff switch. Between him and Captain Telander in the command bridge flowed a mutter of observations. It was not necessary to Leonora Christine. Far less sophisticated craft than she could operate themselves. And she was in fact doing so. Her intermeshing built-in robots worked with more speed and precision—more flexibility, even, within the limits of their programming—than mortal flesh could hope for. But to stand by was a necessity for the men themselves. Elsewhere, the sole direct proof of motion that those had who lay in their cabins was a return of weight. It was not much, under one tenth gee, but it gave them an "up" and "down" for which their bodies were grateful. They released themselves from their beds. Reymont announced over the hall intercom: "Constable to personnel off watch. You may move around ad libitum—forward of your deck, that is." Sarcastically: "You may recall that an official good-by cere­mony, complete with benediction, will be broadcast at Greenwich noon. We'll screen it in the gymnasium for those who care to watch." Reaction mass entered the fire chamber. Thermonuclear generators energized the furious electric arcs that stripped those atoms down to ions; the magnetic fields that separated 20 positive and negative particles; the forces that focused them into beams; the pulses that lashed them to ever higher velocities as they sped down the rings of the thrust tubes, until they emerged scarcely less fast than light itself. Their blast was invisible. No energy was wasted on flames. Instead, everything that the laws of physics permitted was spent on driving Leonora Christine outward. A vessel her size could not accelerate by this means like a Patrol cruiser. That would have demanded more fuel than she could hold, who must carry half a hundred people, and their necessities for ten or fifteen years, and their tools for satisfy­ing scientific curiosity after they arrived, and (if the data beamed by the instrumented probe which had preceded her did actually mean that the third planet of Beta Virginis was habitable) the supplies and machines whereby man could begin to take a new world for himself. She spiraled slowly out of Earth orbit. The dwellers within her had ample chances to stand at her viewscreens and watch home dwindle among the stars. There was no space to spare in space. Every cubic centime­ter inside the hull must work. Yet persons intelligent and sensitive enough to adventure out here would have gone crazy in a ''functional" environment. Thus far the bulkheads were bare metal and plastic. But the artistically talented had plans. Reymont noticed Emma Glassgold, molecular biolo­gist, in a corridor, sketching out a mural that would show forest around a sunlit lake. And from the start, the residential and recreational decks were covered with a material green and springy as grass. The air gusting from the ventilators was more than purified by the plants of the hydroponic section and the colloids of the Darrell balancer. It went through changes of temperature, ionization, odor. At present it smelled like fresh clover—with an appetizing whiff added if you passed the galley, since gourmet food compensates for many depri­vations. Similarly, commons was a warren occupying a whole deck. The gymnasium, which doubled as theater and assem­bly room, was its largest unit. But even the mess was of a size to let diners stretch their legs and relax. Nearby were hobby 21 shops, a clubroom for sedentary games, a swimming pool, tiny gardens and bowers. Some of the ship's designers had argued against putting the dream boxes on this level. Should folk come here for fun be reminded by the door of that cabin that they must have ghostly substitutes for the realities they had left behind them? But the process was, after all, a sort of recreation too; having it in sick bay might be unpleasant, and that was the sole alternative. There was no immediate need for that apparatus. The journey was still young. A slightly hysterical gaiety filled the atmosphere. Men roughhoused, women chattered, laughter was inordinate at mealtimes, and the frequent dances were occasions of heavy flirtation. Passing the gym, which stood open, Reymont saw a handball match in progress. At low gee, when you could virtually walk up a wall, the action got spectacular. He continued to the pool. In an alcove off the principal corridor, it could hold several without crowding; but at this hour, 2100, no one was using it. Jane Sadler stood at the edge, frowning thoughtfully. She was a Canadian, a biotechnician in the organocycle department. Physically she was a big brunette, her features ordinary but the rest of her shown to high advantage by shorts and tee shirt. '' Troubles ?'' Reymont asked. "Oh, hullo, Constable," she responded in English. "Nothing wrong, except I can't figure out how best to deco­rate in here. I'm supposed to make recommendations to my committee." "Didn't they plan on a Roman bath effect?" "Uh-huh. That covers a lot of ground, though. Nymphs and satyrs, or poplar groves, or temple buildings, or what?" She laughed. "Hell with it. I'll suggest N & S. If the job gets botched, it can always be done over, till we run out of paint. Give us something further to do." "Who can keep going five years—and five more, if we have to return—on hobbies?" Reymont said slowly. Sadler laughed again. "Nobody. Don't fret. Everyone aboard has a full program of work lined up, whether it be theoretical research or writing the Great Space Age Novel or teaching Greek in exchange for tensor calculus." 22 ''Of course. I' ve seen the proposals. Are they adequate?'' *'Constable, do relax! The other expeditions made it, more or less sanely. Why not us? Take your swim." She grinned wider. "While you're at it, soak your head." Reymont imitated a smile, removed his clothes, and hung them on a rack. She whistled. "Hey," she said, "I hadn't seen you before in less'n a coverall. That's some collection of biceps and triceps and things you pack around. Calis­thenics?" "In my job, I'd better keep fit," he replied uncomfortably. "Some off watch when you've nothing else to do," she suggested, "come around to my cabin and exercise me." "I'd enjoy that," he said, looking her up and down, "but at present Ingrid and I—'' "Yeah, sure. I was kidding, sort of, anyway. Seems like I'll be making a steady liaison soon myself." "Really? Who, if I may ask?" "Elof Nilsson." She lifted a hand. "No, don't say it. He's not exactly Adonis. His manners aren't always the sweetest. But he's got a wonderful mind, the best in the ship, I suspect. You don't get bored listening to him." Her gaze shifted aside. "He's pretty lonely too." Reymont stood quiet for a moment. "And you're pretty fine, Jane," he said. "Ingrid's meeting me here. Why don't you join us?" She cocked her head. "By golly, you do keep a human being hidden under that policeman. Don't worry, I won't let out your secret. And I won't stay, either. Privacy's hard to come by. You two use this while you've got it." She waved and left. Reymont peered after her and back down into the water. He was standing thus when Lindgren arrived. "Sorry I'm late," she said. "Beamcast from Luna. Another idiotic inquiry about how things are going for us. I'll be positively glad when we get out into the Big Deep." She kissed him. He hardly responded. She stepped back, trouble clouding her face. "What's the matter, darling?" "Do you think I'm too stiff?" he blurted. She had no instant reply. The fluorolight gleamed on her tawny hair, a ventilator's breeze ruffled it a little, the noise of 23 the ball game drifted through the entrance arch. Finally: "What makes you wonder?" ' 'A remark. Well meant, but a slight shock just the same.'' Lindgren frowned. "I've told you before, you've been heavier-handed than I quite liked, the few times you've had to make somebody toe the line. No one aboard is a fool, a malingerer, or a saboteur." "Should I not have told Norbert Williams to shut up the other day, when he started denouncing Sweden at mess? Things like that can have a rather nasty end result.'' Reymont laid a clenched fist in the other palm. "I know," he said. 4'Military-type discipline isn't needed, isn't desir­able . . . yet. But I've seen so much death, Ingrid. The time could come when we won't survive, unless we can act as one and jump to a command." "Well, conceivably on Beta Three," Lindgren admitted. ' 'Though the robot didn't send any data suggesting intelligent life. At most, we might encounter savages armed with spears—who would probably not be hostile to us." ' 'I was thinking of hazards like storms, landslips, diseases, God knows what on an entire world that isn't Earth. Or a disaster before we get there. I'm not convinced modern man knows everything about the universe." "We've covered this ground too often." "Yes. It's old as space flight; older. That doesn't make it less real.'' Reymont groped for sentences. "What I'm trying to do is—I'm not sure. This situation is not like any other I was ever in. I'm trying to ... somehow . . . keep alive some idea of authority. Beyond simple obedience to the articles and the officers. Authority which has the right to command anything, to command a man to death, if that's needful for saving the rest—'' He stared into her puzzlement. "No," he sighed, "you don't understand. You can't. Your world was always good." "Maybe you can explain it to me, if you say it enough different ways.'' She spoke softly.' 'And maybe I can make a few things clear to you. It won't be easy. You've never taken off your armor, Carl. But we'll try, shall we?" She smiled and slapped the hardness of his thigh. "Right now, though, silly, we're supposed to be off duty. What about that swim?" 24 She slipped out of her garments. He watched her approach him. She liked strenuous sports and lying under a sun lamp afterward. It showed in full breasts and hips, slim waist, long supple limbs, a tan against which her blondness stood vivid. "Bozhe moi, you're beautiful!" he said low in his throat. She pirouetted. "At your service, kind sir—if you can catch me!'' She made four low-gravity leaps to the end of the diving board and plunged cleanly off it. Her descent was dreamlike slow, a chance for aerial ballet. The splash when she struck made lingering lacy patterns. Reymont entered directly from the poolside. Swimming was hardly different under this acceleration. The thrust of muscles, the cool silken flowing of water, would be the same at the galaxy's rim, and beyond. Ingrid Lindgren had said once that such truths made her doubt she would ever become really homesick. Man's house was the whole cosmos. Tonight she frolicked, ducking, dodging, slipping from his grasp again and again. Their laughter echoed between the walls. When at last he cornered her, she embraced his neck in turn, laid her lips to his ear and whispered: "Well, you did catch me." "M-m-m-hm." Reymont kissed the hollow between shoulder and throat. Through the wetness he smelled live girlflesh. "Grab our clothes and we'll go." He carried her six kilos easily on one arm. When they were alone in the stairwell, he caressed her with his free hand. She kicked her heels and giggled. "Sensualist!" "We'll soon be back under a whole gee," he reminded her, and started bounding down to officer level at a speed that would have broken necks on Earth. —Later she raised herself on an elbow and met his eyes with hers. She had set the lights dim. Shadows moved behind her, around her, making her doubly gold- and amber-hued. With a finger she traced his profile. "You're a wonderful lover, Carl," she murmured. "I've never had a better." "I'm fond of you too," he said. A hint of pain touched brow and voice. "But that's the only time you really give of yourself. And do you, altogether, even then?" 25 4'What is there to give?" His tone roughened. "I've told you about things that happened to me in the past." "Anecdotes. Episodes. No connection, no— There at the pool, for the first time, you offered me a glimpse of what you are. The tiniest possible glimpse, and you hid it away at once. Why? I wouldn't use the insight to hurt you, Carl." He sat up, scowling. "I don't know what you mean. People learn about each other, living together. You know I admire classical artists like Rembrandt and Bonestell, and don't care for abstractions or chromodynamics. I'm not very musical. I have a barrack-room sense of humor. My politics are conservative. I prefer tournedos to filet mignon but wish the culture tanks could supply us with either more often. I play a wicked game of poker, or would if there were any point in it aboard this ship. I enjoy working with my hands and am good at it, so I'll be helping build the laboratory facilities once that project gets organized. I'm currently trying to read War and Peace but keep falling asleep." He smote the mattress. "What more do you need?" "Everything," she answered sadly. She gestured around the room. Her closet happened to stand open, revealing the innocent vanity of her best gowns. The shelves were filled with her private treasures, to the limit of her mass allowance—a battered old copy of Bellman, a lute, a dozen pictures waiting their turn to be hung, smaller portraits of her kinfolk, a Hopi kachina doll . . . "You brought nothing personal." "I've traveled light through life." ' 'On a hard road, I think. Maybe someday you'll dare trust me." She drew close to him.' 'Never mind now, Carl. I don't want to harass you. I want you in me again. You see, this has stopped being a matter of friendship and convenience. I've fallen in love with you." When the appropriate speed was reached, lining out of Earth's domain toward that sign of the zodiac where the Virgin ruled, Leonora Christine went free. Thruster scold, she became another comet. Gravitation alone worked upon her, bending her path, diminishing her haste. It had been allowed for. But the effect must be kept 26 minimal. The uncertainties of interstellar navigation were too large as was, without adding an extra factor. So the crew— the professional spacemen, as distinguished from the scien­tific and technical personnel—worked under a time limit. Boris Fedoroff led a gang outside. Their job was tricky. You needed skill to labor in weightlessness and not exhaust yourself trying to control tools and body. The best of men could still let both bondsoles lose their grip on the ship frame. You would float off, cursing, nauseated by spin forces, until you brought up at the end of your lifeline and hauled yourself back. Lighting was poor: unshielded glare in the sun, ink blackness in shadow except for what puddles of undiffused radiance were cast by helmet lamps. Hearing was no better. Words had trouble getting through the sounds of harsh breath and thuttering blood, when these were confined in a spacesuit, and through the cosmic seething in radio earplugs. For lack of air purification comparable to the ship's, gaseous wastes were imperfectly removed. They accumulated over hours until you toiled in a haze of sweat smell, water vapor, carbon dioxide, hydrogen sulfide, acetone . . . and your undergarments clung sodden to your skin . . . and you looked wearily through your faceplate at the stars, with a band of headache behind your eyes. Nevertheless, the Bussard module, the hilt and pommel of the dagger, was detached. Maneuvering it away from the vessel was tough, dangerous labor. Without friction or weight, it kept every gram of its considerable inertial mass. It was as hard to stop as to set in motion. Finally it trailed aft on a cable. Fedoroff checked the positioning himself. "Done," he grunted. "I hope." His men clipped their lifelines to the cable. He did likewise, spoke to Telander in the bridge, and cast off. The cable was reeled back inboard, taking the engineers along. They had need for haste. While the module would follow the hull on more or less the same orbit, differential influences were acting. They would soon cause an undesirable shift in relative alignments. But everyone must be inside before the next stage of the process. The forces about to be established would not be kind to living organisms. Leonora Christine extended her scoopfield webs. They 27 glistened in the sunlight, silver across starry black. From afar she might have suggested a spider, one of those adventurous little arachnids that went flying off with kites made of dewy silk. She was not, after all, anything big or important in the universe. Yet what she did was awesome enough on the human scale. Her interior power plant sent energy coursing into the scoopfield generators. From their controlling web work sprang a field of magnetohydrodynamic forces—invisible but reaching across thousands of kilometers; a dynamic interplay, not a static configuration, but maintained and adjusted with nigh absolute precision; enormously strong but even more enormously complex. The forces siezed the trailing Bussard unit, brought it into micrometrically exact position with respect to the hull, locked it in place. Monitors verified that everything was in order. Captain Telander made a final check with the Patrol on Luna, received his go-ahead, and issued a command. From then on, the robots took over. Low acceleration on ion thrust had built up a modest outward speed, measurable in tens of kilometers per second. It sufficed to start the star-drive engine. The power available increased by orders of magnitude. At a full one gravity, Leonora Christine began to move! 28 Chapter 4 In one of the garden rooms stood a viewscreen tuned to Outside. Sable and diamonds were startlingly framed by ferns, orchids, overarching fuchsia and bougainvillea. A fountain tinkled and glittered. The air was warmer here than in most places aboard, moist, full of perfumes and greenness. None of it quite did away with the underlying pulse of driving energies. Bussard systems had not been developed to the smoothness of electric rockets. Always, now, the ship whispered and shivered. The vibration was faint, on the very edge of awareness, but it wove its way through metal, bones, and maybe dreams. Emma Glassgold and Chi-Yuen Ai-Ling sat on a bench among the flowers. They had been walking about, feeling their way toward friendship. Since entering the garden, however, they had fallen silent. Abruptly Glassgold winced and pulled her vision from the screen. "It was a mistake to come here," she said. "Let us go." "Why, I find it charming," the planetologist answered, surprised. "An escape from bare walls that we'll need years to make sightly." 4 'No escape from that.'' Glassgold pointed at the screen. It happened at the moment to be scanning aft and so held an image of the sun, shrunken to the brightest of the stars. Chi-Yuen regarded her narrowly. The molecular biologist was likewise small and dark-haired, but her eyes were round and blue, her face round and pink, her body a trifle on the dumpy side. She dressed plainly whether working or not; and without snubbing social activities, she had hitherto been observer rather than participant. "In—how long?—a couple of weeks," she continued, "we have reached the marches of the Solar System. Every day—no, every twenty-four hours; 'day' and 'night' mean 29 nothing any longer—each twenty-four hours we gain 845 kilometers per second in speed." "A shrimp like me is grateful to have full Earth weight," Chi-Yuen said with attempted lightness. "Don't misunderstand me," Glassgold replied hastily. "I won't scream, 'Turn back! Turn back!' " She tried a joke of her own. "That would be too disappointing to the psycholo­gists who checked me out." The joke dissipated. "It is only ... I find I require time ... to get used, piece by piece, to this." Chi-Yuen nodded. She, in her newest and most colorful cheong-sam—among her hobbies was making over her clothes—could almost have belonged to a different species from Glassgold. But she patted the other woman's hand and said: "You are not unique, Emma. It was expected. People begin to realize with more than brains, in their whole beings, what it means to be on such a voyage." "You don't seem bothered." "No. Not since Earth disappeared in the sun glare. And not unbearably before. It hurt to say good-by. But I've had experience in that. One learns how to look forward." "I am ashamed," Glassgold said. "When I have had so much more than you. Or has that made me soft in the spirit?" "Have you really?" Chi-Yuen's question was muted. "Why . . . yes. Haven't I? Or don't you recall? My parents were always well-to-do. Father is an engineer in a desalinization plant, Mother an agronomist. The Negev is beautiful when the crops are growing and calm, friendly, not hectic like Tel Aviv or Haifa. Though I did enjoy studying at the university. I had chances to travel, with good compan­ions. My work went fine. Yes, I was lucky." "Then why did you enlist for Beta Three?" "Scientific interest ... a whole new planetary evolu­tion—" "No, Emma." The raven's wing tresses stirred as Chi-Yuen shook her head. "The earlier starships brought back data to keep research going for a hundred years, right on Earth. What are you running from?" Glassgold bit her lip. "I shouldn't have pried," Chi-Yuen apologized. "I was hoping to help." 30 "I will tell you,'5 Glassgold said. "I have a feeling you might indeed help. You are younger than me, but you have seen more.'' Her fingers knitted together in her lap. "I'm not quite sure, though, myself. How did the cities begin to seem vulgar and empty? And when I went home to visit my people, the countryside seemed smug and empty. I thought I might find ... a purpose? , . . out here. I don't know. I applied for the berth on impulse. When I was called for serious testing, my parents made a fuss till I could npt back down. And yet we were always a close family. It was such a pain leaving them. My big, confident father, he was suddenly little and old." "Was a man involved too?" Chi-Yuen asked. 'Til tell you, because it's no secret—he and I were engaged, and everything about this crew that was ever on public record went into the dossiers—there was for me." "A fellow student," Glassgold said humbly. "I loved him. I still do. He hardly knew I existed." "Not uncommon," Chi-Yuen answered. "One gets over it, or else turns it into a sickness. You're healthy in the head, Emma. What you need is to come out of your shell. Mix with your shipmates. Care about them. Get out of your cabin for a while and into a man's." Glassgold flushed. "I don't hold with those practices." Chi-Yuen's brows lifted. "Are you a virgin? We can't afford that, if we're to start a new race on Beta Three. The genetic material is scarce at best." ' 'I want a decent marriage,'' Glassgold said with a flick of anger, "and as many children as God gives me. But they will know who their father is. It doesn't hurt if I don't play any ridiculous game of musical beds while we travel. We have enough girls aboard who do." "Like me." Chi-Yuen was unruffled. "No doubt stable relationships will evolve. Meanwhile, now and then, why not give and get a few moments of pleasure?" ' Tm sorry,'' Glassgold said. ' 'I shouldn't criticize private matters. Especially when lives have been as different as yours and mine." "True. I don't agree that mine was less fortunate than yours. On the contrary." 31 "What?" Glassgold's mouth fell open. "You can't be serious!" Chi-Yuen smiled. "You have only learned the surface of my past, Emma, if that. I can guess what you're thinking. My country divided, impoverished, spastic from the aftermath of revolutions and civil wars. My family cultured and tradition-minded but poor with the desperate poverty that none except aristocrats fallen on evil times know. Their sacrifices to keep me in the Sorbonne, when the chance came. After I got my degree, the hard work and sacrifice I made in return, helping them get back on their feet." She turned her face to the ebbing light of Sol and added most quietly: * 'About my man. We, too, were students together, in Paris. Later, as I said, I must often be away from him because of work. Finally he went to visit my parents in Peking. I was to join him as soon as possible, and we would be married, in law and sacrament as well as in fact. A riot happened. He was killed." "Oh, my dear—" Glassgold began. "That's the surface," Chi-Yuen interrupted. "The sur­face. Don't you see, I also had a loving home, perhaps more than you did, because at the end they understood me so well that they didn't resist my leaving them forever. I saw a lot of the world, more than can be seen traveling carefully by first class. I had my Jacques. And others, before, afterward, as he would have wanted. I'm outward bound with no regrets and no pain that won't heal. The luck is mine, Emma." Glassgold did not respond with words. Chi-Yuen took her by the hand and stood up. "You must break free of yourself," the planetologist said. "In the long run, only you can teach you how to do that. But maybe I can help a little. Come down to my cabin. We'll make you a gown that does you justice. The Covenant Day party will be soon, and I intend for you to have fun." Consider: a single light-year is an inconceivable abyss. Denumerable but inconceivable. At an ordinary speed—say, a reasonable pace for a car in megalopolitan traffic, two kilometers per minute—you would consume almost nine 32 million years in crossing it. And in Sol's neighborhood, the stars averaged some nine light-years apart. Beta Virginis was thirty-two distant. Nevertheless, such spaces could be conquered. A ship accelerating continuously at one gravity would have traveled half a light-year in slightly less than one year of time. And she would be moving very near the ultimate velocity, three hundred thousand kilometers per second. Practical problems arose. Where was the mass-energy to do this coming from? Even in a Newtonian universe, the thought of a rocket, carrying that much fuel along from the start, would be ludicrous. Still more so was it in the true, Einsteinian cosmos, where the mass of ship and payload increased with speed, climbing toward infinity as that speed approached light's. But fuel and reaction mass were there in space! It was pervaded with hydrogen. Granted, the concentration was not great by terrestrial standards: about one atom per cubic cen­timeter in the galactic vicinity of Sol. Nevertheless, this made thirty billion atoms per second, striking every square cen­timeter of the ship's cross section, when she approximated light velocity. (The figure was comparable at earlier stages of her voyage, since the interstellar medium was denser close to a star.) The energies were appalling. Megaroentgens of hard radiation would be released by impact; and less than a thousand r within an hour are fatal. No material shielding would help. Even supposing it impossibly thick to start with, it would soon be eroded away. However, in the days of Leonora Christine non-material means were available: magnetohydrodynamic fields, whose pulses reached forth across millions of kilometers to seize atoms by their dipoles—no need for ionization—and control their streaming. These fields did not serve passively, as mere armor. They deflected dust, yes, and all gases except the dominant hydrogen. But this latter was forced aft—in long curves that avoided the hull by a safe margin—until it entered a vortex of compressing, kindling electromagnetism centered on the Bussard engine. 33 The ship was not small. Yet she was the barest glint of metal in that vast web of forces which surrounded her. She herself no longer generated them. She had initiated the proc­ess when she attained minimum ramjet speed; but it became too huge, too swift, until it could only be created and sus­tained by itself. The primary thermonuclear reactors (a sepa­rate system would be used to decelerate), the venturi tubes, the entire complex which thrust her was not contained inboard. Most of it was not material at all, but a resultant of cosmic-scale vectors. The ship's control devices, under com­puter direction, were not remotely analogous to autopilots. They were like catalysts which, judiciously used, could affect the course of those monstrous reactions, could build them up, in time slow them down and snuff them out . . . but not fast. Starlike burned the hydrogen fusion, aft of the Bussard module that focused the electromagnetism which contained it. A titanic gas-laser effect aimed photons themselves in a beam whose reaction pushed the ship forward—and which would have vaporized any solid body it struck. The process was not 100 per cent efficient. But most of the stray energy went to ionize the hydrogen which escaped nuclear combus­tion. These protons and electrons, together with the fusion products, were also hurled backward by the force fields, a gale of plasma adding its own increment of momentum. The process was not steady. Rather, it shared the instabil­ity of living metabolism and danced always on the same edge of disaster. Unpredictable variations occurred in the matter content of space. The extent, intensity, and configuration of the force fields must be adjusted accordingly—a problem in ? million factors which only a computer could solve fast enough. Incoming data and outgoing signals traveled at light speed: finite speed, requiring a whole three and a third seconds to cross a million kilometers. Response could be fatally slow. This danger would increase as Leonora Chris­tine got so close to ultimate velocity that time rates began measurably changing. Nonetheless, week by week, month by month, she moved on outward. 34 The multiple cyclings of matter that turned biological wastes back into breathable air, potable water, edible food, usable fiber, went so far as to maintain an equilibrium in the ethyl alcohol aboard. Wine and beer were produced in mod-eraticn, mainly for the table. The hard liquor ration was meager. But certain people had included bottles in their personal baggage. Furthermore, they could trade for the share of abstemious friends and save their own issue until it sufficed for a special occasion. No official rule, but evolving custom, said that drinking outside the cabins took place in the mess. To promote socia­bility, this room held several small tables rather than a single long one. Hence, between meals, it could double as a club. Some of the men built a bar at one end to dispense ice and mixers. Others made roll-down curtains for the bulkheads, so that the decorous murals could be hidden during boozing hours behind scenes a little more ribald. A taper generally kept background music going, cheerful stuff, anything from sixteenth-century galliards to the latest asteroid ramble received from Earth. On a particular date at about 2000 hours, the club stood empty. A dance was scheduled in the gym. Most off-duty personnel who wished to attend it—the majority—were get­ting dressed. Garments, all ceremony, were becoming ter­ribly important. Machinist Johann Freiwald shone in a gilt tunic and silvercloth trews that a lady had made for him. She wasn't ready yet, nor was the orchestra, so he allowed Elof Nilsson to lead him to the bar. "Can we not talk business tomorrow, though?" he asked. He was a large, amiable young man, square-featured, his scalp shining pink through close-cropped blond hair. "I want to discuss this with you at once, while it's new in my mind," said Nilsson's raspy voice. "It came to me in a flash as I was changing clothes." His appearance bore him out. "Before carrying my thought further, I wish to check the practicality." " Jawohl, if you're supplying the drink and we can keep it short." The astronomer found his personal bottle on the shelf, 35 picked up a couple of glasses, and started for a table. "I take water—" Freiwald began. The other man didn't hear. ' 'That's Nilsson for you," Freiwald told the overhead. He tapped a pitcherful and brought it along. Nilsson sat down, got out a note pad, and started sketching. He was short, fat, grizzled, and ugly. It was known that an intellectually ambitious father, in the ancient university town Uppsala, had forced him to become a prodigy at the expense of everything else. It was surmised that his marriage had been the result of mutual desperation and had turned into a prolonged catastrophe, for despite a child it dissolved the moment he got a chance to go on this ship. Yet when he talked, not about the humanities he failed to under­stand and hence disdained, but about his own sub­ject . . . then you forgot his arrogance and flatulence, you remembered his observations which had finally proven the oscillating universe, and you saw him crowned with stars. ''—unparalleled opportunity to get some worthwhile read­ings. Only think what a baseline we'll have: ten parsecs! Plus the ability to examine gamma-ray spectra with less uncer­tainty, high precision, when they're red-shifted down to less energetic photons. And more and more. Still, I'm not satis­fied. "I don't believe it's really necessary for me to peer at an electronic image of the sky—narrow, blurred, and degraded by noise, not to mention the damned optical changes. We should mount mirrors outside the hull. The images they catch could be led along light conductors to eyepieces, photomul-tipliers, cameras inboard. ' 'No, don't say it. I'm well aware that previous attempts to do this failed. One could build a machine to go out through an airlock, shape the plastic backing for such an instrument, and aluminize it. But induction effects of the Bussard fields would promptly make the mirror into something appropriate for a fun house in Grona Lund. Yes. "Now my idea is to print sensor and feedback circuits into the plastic, controlling flexors that'll automatically compen­sate these distortions as they occur. I would like your opinion as to the feasibility of designing, testing, and producing those 36 flexors, Mr. Freiwald. Here, this is a rough drawing of what I have in mind—" / Nilsson was interrupted. "Hey, thereyouare, oV buddy!" He and the machinist looked up. Williams lurched toward them. The chemist held a bottle in his right hand, a half-full tumbler in the left. His face was redder than usual and he breathed heavily. " Was zum Teufel?" Freiwald exclaimed. "English, boy," Williams said. "Talk English tonight. 'Merican style.'' He reached the table, set his burdens down, and rested on it so hard it almost tipped over. A powerful whisky smell hung around him. "You 'specially, Nilsson." He pointed with an oscillant finger. "You talk American tonight, you Swede. Hear me?" "Please go elsewhere," the astronomer said. Williams plumped himself onto a chair. He leaned forward on both elbows. ' 'You don't know what day this is," he said. "Do you?" "I doubt you do, in your present condition," Nilsson snapped, remaining with Swedish. "The date is the fourth of July." "R-r-r-right! Y' know what 'at means? No?" Williams turned to Freiwald. "You know, Heinie?" "An, uh, anniversary?" the machinist ventured. "Right. Anniversary. How'dyuh guess?" Williams lifted his glass. "Drink wi' me, you two. Been collectin' f today. Drink!" Freiwald gave him a sympathetic glance and clinked rims. "Prosit. " Nilsson started to say, "Skal," but set his own liquor down again and glared. "Fourth July," Williams said. "Independence Day. My country. Wanted throw party. Nobody cared. One drink with me, two maybe, then gotta go their goddam dance." He regarded Nilsson for a while. "Swede," he declared slowly, "you'll drink wi' me 'r I'll bust y'r teeth in." Freiwald laid a muscular hand on Williams' arm. The chemist tried to rise. Freiwald held him where he was. "Be calm, please, Dr. Williams," the machinist requested mildly. "If you want to celebrate your national day, why, we'll be 37 glad to toast it. Won't we, sir?" he added to Nilsson. The astronomer clipped: "I know what the matter is. I was told before we left, by a man who knew. Frustration. He couldn't cope with modern management procedures." "Goddam welfare state bureaucracy," Williams hic-cuped. "He started dreaming of his country's sovereign, imperial era," Nilsson went on. "He fantasized about a free enter­prise system that I doubt ever existed. He dabbled in reaction­ary politics. When the Control Authority had to arrest several high American officials on charges of conspiracy to violate the Covenant—" "I'd had a bellyful." Williams' tone rose toward a shout. " 'Nother star. New world. Chance t' be free. Even if I do have to travel with a pack o' Swedes." "You see?" Nilsson grinned at Freiwald. "He's nothing but a victim of the romantic nationalism that our too orderly world has been consoling itself with, this past generation. Pity he couldn't be satisfied with historical fiction and bad epic poetry." "Romantic!" Williams yelled. He struggled fruitlessly in Freiwald's grip. "You pot-gutted spindle-shanked owl-eyed freak, wha'd'you think it did to you? How'd it feel, being built like that, when the other kids were playing Viking? Your marriage washed out worse'n mine! And I did cope, you son of a bitch, I was meet'n' my payroll, something you never had to do, you— Lemme go an' we'll see who's a man here!" "Please," Freiwald said. "Bitte. Gentlemen." He was standing, now, to keep Williams held in the chair. His gaze nailed Nilsson across the table. "And you, sir," he continued sharply. "You had no right to bait him. You might have shown the courtesy to toast his national day." Nilsson seemed about to pull intellectual rank. He broke off when Jane Sadler appeared. She had been in the door for a couple of minutes, watching. Her expression made her for­mal gown pathetic. "Johann's telling you truth, Elof," she said. "Better come along." "And dance?" Nilsson gobbled. "After this?" 38 "Especially after this." She tossed her head. "I've grown pretty tired of you on your high horse, dear. Shall we try to start fresh, or drop everything as of now?" Nilsson muttered but rose and offered her his arm. She was a little taller than he. Williams sat slumped, struggling not to weep. "I'll stay here awhile, Jane, and see if I can't cheer him up," Freiwald whispered to her. She gave him a troubled smile. "You would, Johann." They had been together a few times before she took up with Nilsson. "Thanks." Their glances lingered, each on each. Nilsson shuffled his feet and coughed. "I'll see you later," she said, and left. 39 Chapter 5 When Leonora Christine attained a substantial fraction of light speed, its optical effects became clear to the unaided sight. Her velocity and that of the rays from a star added vectorially; the result was aberration. Except for whatever lay dead aft or ahead, the apparent position changed. Con­stellations grew lopsided, grew grotesque, and melted, as their members crawled across the dark. More and more, the stars thinned out behind the ship and crowded before her. Doppler effect operated simultaneously. Because she was fleeing the light waves that overtook her from astern, to her their length was increased and their frequency lowered. In like manner, the waves into which her bow plunged were shortened and quickened. Thus, the suns aft looked ever redder, those forward bluer. On the bridge stood a compensating viewscope: the single one aboard, elaborate as it was. A computer figured out continuously how the sky would appear if you were motion­less at this point in space, and projected a simulacrum of it. The device was not for amusement or comfort; it was a valuable navigational aid. Clearly, though, the computer needed data on where the ship really was and how fast she was traveling with respect to objects in heaven. This was no simple thing to find out. Velocity—exact speed, exact direction—varied with varia­tions in the interstellar medium and with the necessarily imperfect feedback to the Bussard controls, as well as with time under acceleration. The shifts from her calulated path were comparatively petty; but over astronomical distances, any imprecisions could add up to a fatal sum. They must be eliminated as they occurred. Hence that neat, stocky, dark-bearded man, Navigation Officer Auguste Boudreau, was among the few who had a 40 full-time job en route that was concerned with operating the ship. It did not quite require him to revolve in a logical circle—find your position and velocity so you can correct for optical phenomena so you can check your position and veloc­ity. Distant galaxies were his primary beacons; statistical analysis of observations made on closer individual stars gave him further data; he used the mathematics of successive approximations. This made him a collaborator of Captain Telander, who computed and ordered the needful course changes, and of Chief Engineer Fedoroff, who put them into execution. The task was smoothly handled. No one sensed the adjustments, except as an occasional minute temporary increase in the liminal throbbing of the ship, a similarly small and transitory change in the acceleration vector, which felt as if the decks had tilted a few degrees. In addition, Boudreau and Fedoroff tried to maintain con­tact with Earth. Leonora Christine was still detectable by space-borne instruments in the Solar System. Despite the difficulties created by her drive fields, the Lunar maser beam could still reach her with inquiries, entertainment, news, and personal greetings. She could still reply on her own transmit­ter. In fact, such talk back and forth was expected to become regular, once she was well established at Beta Virginis. Her unmannned precursor had had no problem with sending information. It was doing so at the present moment, although the ship could not receive that and the crew intended to read its tapes when they arrived. The present trouble was this: Suns and planets are big, staid objects. They move through space at reasonable speeds, seldom above fifty kilometers per second. And they do not zigzag, however slightly. It is simple to predict where they will be centuries from now, and aim a message beam accord­ingly. A starship is something else. Men don't last long; they must hurry. Aberration and Doppler shift affect radio too. Eventually the transmissions from Luna would enter on fre­quencies that nothing aboard the vessel could receive. Well before then, however, through one unforeseeable factor or another, when travel time between maser projector and ship stretched into months, the beam was sure to lose her. 41 Fedoroff, who was also the communications officer, tink­ered with detectors and amplifiers. He strengthened the sig­nals which he punched Sol ward, hoping they would give clues to his future location. Though days might go by without a break in the silence, he persevered. He was rewarded with success. But the quality of reception was always poorer, the interval of it shorter, the time»till the next longer as Leonora Christine entered the Big Deep. Ingrid Lindgren pushed the buzzer button. The cabins were sufficiently soundproofed that a knock would never pass. There was no response. She tried again, drawing another blank. She hesitated, frowning, shifting from foot to foot. At length she laid hand on catch. The door wasn't locked. She opened it a crack. Not looking through, she called softly, "Boris. Are you all right?" Sounds reached her, a creak, a rustle, slow heavy foot­steps. Fedoroff threw the door wide. "Oh," he said. "Good day." She regarded him. He was a burly man of medium stature, face broad and high in the cheekbones, brown hair salted with gray although his biological age was a mere forty-two. He hadn't shaved for several watches and wore nothing except a robe, obviously thrown on this minute. "May I come in?" she requested. "If you wish." He waved her past him and closed the door. His half of the unit had been screened off from the part currently occupied by Biosystems Chief Pereira. An unmade bed filled most of it. A vodka bottle stood on the dresser. "Pardon the mess," he said indifferently. Lumbering past her: "Would you like a drink? I didn't bring tumblers, but you needn't fear a pull on this. Nobody has anything conta­gious ." He chuckled, or rather rattled. "Where would germs come from, here?" Lindgren sat down on the edge of the bed. "No, thanks," she replied. "I'm on duty." "And I'm supposed to be. Yes." Fedoroff loomed over her, slumping. "I informed the bridge I feel indisposed and had better take a rest." "Shouldn't Dr. Latvala examine you?" 42 4 'What for? I'm physically well.'' Fedoroff paused. *'You came to make sure of me." 4 Tart of my job. I'll respect your privacy. But you are a key man." Fedoroff smiled. The expression was as forced as the prior noise had been. "Don't worry," he said. * 'I am not breaking down in the brain either." He reached for the bottle, then withdrew his arm. "I am not even glugging myself into a stupor. It is nothing except a . . . what do the Americans call it? ... aglow." 4'Glows are best in company,'' Lindgren declared. After a moment: "I believe I will accept that drink." Fedoroff gave her the bottle and joined her on the bedside. She raised it to him. ''Skal.'' A scant amount went down her throat. She returned the bottle, and he gave her "Zdoroviye. " They sat in silence, Fedoroff gazing at the bulkhead, until he stirred and said: 4'Very well. Since you must know. I wouldn't tell anyone else, especially not a woman. But I have come to learn something about you, Ingrid . . . Gunnar's daughter, is that correct?" "Yes, Boris Ilyitch." He gave her a glance and a more nearly genuine smile. She sat relaxed, body curving out her coverall, a hint of warmth and human odor around her. "I believe—" his tongue fum­bled—' 'I hope you will understand, and not repeat what I tell you." "I promise the silence. For understanding, I can try." " 44 He put elbows on knees, hands straining against each other. "It is personal, you see," he said slowly and not quite evenly. "Yet no great matter. I will be over it soon. It is simple . . . that final cast we received . . . upset me." The music?" Yes. Music. Signal-to-noise ratio too low for television. Almost too low for sound. The last we will get, Ingrid Gunnar's daughter, before we reach goal and start receiving messages a generation old. I am certain it was the last. Those few minutes, wavering, fading in and out, scarcely to hear through the fire-crackle of stars and cosmic rays—when we lost that music, I knew we would get no more." 43 Fedoroff s voice trailed off. Lindgren waited. He shook himself. "It happened to be a Russian cradle song," he said. "My mother sang me to sleep with it." She laid a hand on his shoulder and let it rest, feather-light. "Do not think I am off on an orgy of self-pity," he added in haste. ' Tor a short while I remember my dead too well. It will pass." "Maybe I do understand," she murmured. He was on his second interstellar trip. He had gone to Delta Pavonis. Probe data indicated an Earthlike planet, and the expedition left with flying hopes. The reality was so night­marish that the survivors showed rare heroism in remaining and studying for the minimum planned time. On their return, they had experienced twelve years; but Earth had aged forty-three. "I doubt if you do, really." Fedoroff turned to confront her. "We expected people would have died when we came home. We expected change. If anything, I was overjoyed at first that I could recognize parts of my city—moonlight on canals and river, domes and towers on Kazan Cathedral, Alexander and Bucephalus rearing over the bridge that car­ries Nevsky Prospect, the treasures in the Hermitage—" He looked back away and shook his head wearily. "But the life itself. That was too different. Meeting it was like, like seeing a woman one loved become a slut.'' He fleered. "Exactly so! I worked in space for five years, as much as I was able, research and development on improving the Bussard engine, as you may remember. My main purpose was to earn the post I have. We can hope for a fresh beginning on Beta Three." His words grew barely audible: "Then my mother's little song reached me. For the last time.'' He tilted the bottle to his lips. Lindgren gave him a minute or two of silence before: "Now I can see, Boris, in part, why it hurt you so. I've studied a bit of sociohistory. In your boyhood, people were less, well, less relaxed. They'd repaired the war damage in most countries and brought population growth and civil dis­order under control. Now they were going on to new things, imagination-staggering projects, on Earth as well as in space. Nothing seemed impossible. At the core of their elan was a 44 spirit of hard work, patriotism, dedication. I suppose you had two gods you served with a whole heart, Father Technics and Mother Russia." Her hand slipped down to lie upon his. "You returned," she said, "and nobody cared." He nodded. Teeth caught at his lower lip. "Is that why you despise today's women?" she asked. He started. "No! Never!" "Why, then, have none of your liaisons lasted beyond a week or two—mostly a single off watch at a time?" she challenged him. ' 'Why are you only at ease and merry among men? I believe you don't care to know our half of the human race except as bodies. You don't think there's anything else worth knowing. And what you said a minute ago, about sluts—" "I came from Delta Pavonis wishing for a true wife," he answered as if being strangled. Lindgren sighed. "Boris, mores change. From my view­point, you grew up in a period of unreasonable puritanism. But it was a reaction to an earlier easiness that had perhaps gone too far; and earlier yet— No matter." She chose her words with care, "The fact is, man has never stayed by a single ideal. The mass enthusiasm when you were young gave way to cool, rationalistic classicism. Today that's being drowned in turn by a kind of neoromanticism. God knows where that will lead. I probably won't approve. Regardless, new generations grow up. We've no right to freeze them into our own mold. The universe is too wide." Fedoroff was unmoving for so long that she started to rise and go. Suddenly he whirled, caught her wrist, and pulled her back down beside him. His speech labored. "I would like to know you, Ingrid, as a human being." "I'm glad." His mouth tightened. "You had better leave now, though,'' he got out.' 'You are with Reymont. I don't want to cause trouble." "I want you for a friend too, Boris," she said. "I've admired you since we first met. Courage, competence, kind­liness—what else is there to admire in a man? I wish you could learn to show them to your shipmates that happen to be female." 45 He opened his grasp on her. "I warn you to go." She considered him. "If I do," she asked, "and we get to talking another time, will you be at ease with me?" "I don't know," he said. "I hope it, but I don't know." She thought awhile further. "Let us try to make sure of it," she suggested finally, gently. "I don't have to be any­where else for the rest of my watch." 46 Chapter 6 Every scientist aboard had planned at least one research project to help fill the half decade of travel. Glassgold's was tracing the chemical basis of the life on Epsilon Eridani Two. After setting up her equipment, she began putting her pro-tophytes and tissue cultures through their experimental paces. In due course she got reaction products and needed to know exactly what they were. Norbert Williams was per­forming analyses for several different people. One day late in the first year, he brought his report on her most recent sample to her laboratory. He had taken to doing this in person. The molecules were strange, exciting him as much as her, and the two of them often discussed the findings for hours on end. Increasingly, the conversation would veer toward other topics. She gave him cheerful greeting as he entered. The work­bench behind which she stood was barricaded with test tubes, flasks, a pH meter, a stirrer, a blender, and more. "Well," she said, "I'm quite agog to learn what metabolites my pets have been making now." "Damnedest mess I ever saw." He tossed down a couple of clipped-together pages. "Sorry, Emma, but you're going to have to run it over. And over and over, I'm afraid. I can't get by with micro quantities. This wants every type of chromatography I've got, plus X-ray diffractions, plus a series of enzyme tests I've listed here, before I'd venture any guess at the structural formulas." "I see," Glassgold replied. "I regret making more work for you." "Shucks, that's what I'm here for, till we reach Beta Three. I'd go nuts without jobs to do, and yours is the most interesting of the lot, I'll tell you." Williams ran a hand through his hair; the loud shirt wrinkled across his shoulder. 47 * 'Though to be frank, I don't understand what's in it for you, other than a pastime. I mean, they're tackling the same problems on Earth, with bigger staff and better facilities. They ought to've cracked your riddles before we come to a stop." "No doubt," she said. "But will they beam the results to us?" "I expect not, unless we inquire. And if we do, we'll be very old, or dead, before the reply arrives." Williams leaned toward her across the bench. "The thing is, why should we care? Whatever type of biology we find at Beta Three, we know it won't resemble this. Are you keeping your hand in? " "Partly that," she admitted. "I do think it will be of practical value. The broader a view I have of life in the universe, the better I should be able to study the particular case where we are going. And so we learn sooner, more certainly, whether we can build our homes there and call others to follow us from Earth." He rubbed his chin. "Yeah, I guess you're right. Hadn't thought of that angle." Awe dwelt beneath the prosaic words. For the expedition was not merely going for a look: not at such cost in resources, labor, skill, dreams, and years. Nor could it hope for any­thing as easy to subdue as America had been. At a minimum, these people would spend another half decade in the Beta Virginis System, exploring its worlds in the ship's auxiliary craft, adding what little they could to the little that the orbiting probe had garnered. And if the third planet really was habitable, they would never come home, not even the professional spacemen. They would live out their lives, and be like their children and grandchildren too, exploring its manifold mysteries and flashing their dis­coveries to the hungry minds on Earth. For indeed, any planet is a world, infinitely varied, infinitely secret. And this world appeared to be so terrestroid that the strangenesses it must hold would be yet the more vivid and enlightening. The folk of Leonora Christine were quite explicit in their ambition to establish that kind of scientific base. Their further, largest hope was that their descendants would find no reason ever to go back: that Beta Three might evolve from 48 base to colony to New Earth to jumping-off place for the next starward leap. There was no other way by which men might possess the galaxy. As if shying away from vistas that could overwhelm her, Glassgold said, reddening a trifle: "Besides, f care about Eridanian life. It fascinates me. I want to know what . . . makes it tick. And as you point out, if we do stay we aren't likely to get the answers told us while we are alive." He fell silent, fiddled with a titration setup, until ship-drive and ventilator breath, sharp chemical odors, bright colors on the reagent and dye shelves, shoved forward into conscious­ness. At length he cleared his throat. "Uh, Emma." "Yes?" She seemed to feel the same diffidence. ' 'How about knocking off? Come on down to the club with me for a drink before dinner. My ration." She retreated behind her instruments. "No, thank you," she said confusedly. "I, I do have a great deal of work." "You have time for it, too," he pointed out, bolder. "Okay, if you don't want a cocktail, what about a cup of coffee? Maybe a stroll through the gardens— Look, I don't aim to make a pass. I'd just like to get better acquainted." She swallowed before she smiled, but then she gave him warmth. "Very well, Norbert. I would like that myself." A year after she started, Leonora Christine was close to her ultimate velocity. It would take her thirty-one years to cross interstellar space, and one year more to decelerate as she approached her target sun. But that is an incomplete statement. It takes no account of relativity. Precisely because there is an absolute limiting speed (at which light travels in vacuo; likewise neutrinos) there is an interdependence of space, time, matter, and energy. The tau factor enters the equations. If v is the (uniform) velocity of a spaceship, and c the velocity of light, then tau equals V2 1-CS The closer that v comes to c, the closer tau comes to zero. 49 Suppose an outside observer measures the mass of the spaceship. The result he gets is her rest mass—i.e., the mass that she has when she is not moving with respect to him— divided by tau. Thus, the faster she travels the more massive she is, as regards the universe at large. She gets the extra mass from the kinetic energy of motion; e=mc2. Furthermore, if the "stationary" observer could compare the ship's clocks with his own, he would notice a disagree­ment. The interlude between two events (such as the birth and death of a man) measured aboard the ship where they take place, is equal to the interlude which the observer measures . . . multiplied by tau. One might say that time moves pro­portionately slower on a star ship. Lengths shrink; the observer sees the ship shortened in the direction of motion by the factor tau. Now measurements made on shipboard are every bit as valid as those made elsewhere. To a crewman, looking forth at the universe, the stars are compressed and have gained in mass; the distances between them have shriveled; they shine, they evolve at a strangely reduced rate. Yet the picture is more complicated even than this. You must bear in mind that the ship has, in fact, been accelerated and will be decelerated in relation to the total background of the cosmos. This takes the whole problem out of special and into general relativity. The star-and-ship situation is not really symmetrical. The twin paradox does not arise. When velocities match once more and reunion takes place, the star will have passed through a longer time than the ship did. If you ran tau down to one one-hundredth and went into free fall, you would cross a light-century in a single year of your own experience. (Though, of course, you could never regain the century that had passed at home, during which your friends grew old and died.) This would inevitably involve a hundredfold increase of mass. A Bussard engine, drawing on the hydrogen of space, could supply that. Indeed, it would be foolish to stop the engine and coast when you could go right on decreasing your tau. Therefore, to reach other suns in a reasonable portion of your life expectancy: Accelerate continuously, right up to the interstellar midpoint, at which point you activate the 50 decelerator system in the Bussard module and start slowing down again. You are limited by the speed of light, which you can never quite reach. But you are not limited in how close you can approach that speed. And thus you have no limit on your inverse tau factor. Throughout her year at one gravity, the differences be­tween Leonora Christine and the slow-moving stars had accumulated imperceptibly. Now the curve entered upon the steep part of its climb. Now, more and more, her folk mea­sured the distance to their goal as shrinking, not simply because they traveled, but because, for them, the geometry of space was changing. More and more, they perceived natural processes in the outside universe as speeding up. It was not yet spectacular. Indeed, the minimum tau in her flight plan, at midpoint, was to be somewhat above 0.015. But an instant came when a minute aboard her corresponded to sixty-one seconds in the rest of the galaxy. A while later, it corresponded to sixty-two. Then sixty-three . . . sixty-four ... the ship time between such counts grew gradually but steadily less . . . sixty-five . . . sixty-six . . . sixty-seven. . . . The first Christmas—Chanukah, New Year's, solstice fes­tival season—that the crew spent together had come early in their voyage and was a feverish carnival. The second was quieter. People were settling down to their work and their fellows. Nevertheless, improvised ornaments glittered on all decks. The hobby rooms resounded, the scissors and needles clicked, the galley grew fragrant with spice, as everybody tried to make small gifts for everybody else. The hydroponics division found it could spare enough green vines and branches for an imitation tree in the gymnasium. From the enormous microtape library came films of snow and sleighs, recordings of carols. The thespian contingent rehearsed a pageant. Chef Carducci planned banquets. Commons and cabins rollicked with parties. By tacit agreement, no one mentioned that each second which passed laid Earth three hundred thousand kilometers farther behind. Reymont made his way through a bustling recreation level. Some groups were stringing up the most newly made decora- 51 tions. Nothing could be wasted, but aluminum-foil chains, blown-glass globes, wreaths twisted from bolts of cloth, were reclaimable. Others played games, chattered, offered drinks around, flirted, got boisterous. Through the chatter and laughter and shuffling, hum and crackle and rustle, music floated out of a loudspeaker: "Adeste, fideles, Laeti, triumphantes, Venite, venite, in Bethlehem.'9 Iwamoto Tetsuo, Hussein Sadek, Yeshu ben-Zvi, Mohandas Chidambaran, Phra Takh, or Kato M'Botu seemed to belong with it as much as Olga Sobieski or Johann Freiwald. The machinist bellowed at Reymont: "Guten Tag, mein lieber Schutzmann! Come share my bottle!" He waved it in the air. His free arm was around Margarita Jimenes. Sus­pended above them was a slip of paper on which had been printed MISTLETOE. Reymont halted. He got along well with Freiwald.' * Thank you, no," he said. "Have you seen Boris Fedoroff? I expected him to come here when he got off work." "N-no. I would expect it too, as lively as things are tonight. He's become a lot happier lately for some reason, hasn't he? What do you want of him?" "Business matter." "Business, forever business," Freiwald said. "I swear your personal amusement is fretting. Me, I've got a better one." He hugged Jimenes to him. She snuggled. "Have you called his cabin?" "Naturally. No response. Still, maybe—" Reymont turned. "I'll try there. Later I'll come back for that schnapps," he added, already leaving. He took the stairs down past crew level to the officers' deck. The music followed. "—Iesu, tibi sit gloria." The passageway was deserted. He pushed Fedoroff's chime button. The engineer opened the door. He was clad in lounging pajamas. Behind him, a bottle of French wine, two glasses, and some Danish-style sandwiches waited on the dresser top. 52 Surprise jarred him. He took a backward step. "Chto— you?" 4'Could I speak with you?" "Um-m-m." Fedoroff' s glance flickered. "I expect a guest." Reymont grinned. "That's obvious. Don't worry, I won't linger. But this is rather urgent." Fedoroff bridled. "It cannot wait until I am on duty?" "The thing is, it had better be discussed confidentially," Reymont said. "Captain Telander agrees." He slipped around Fedoroff, into the cabin. "An item was overlooked in the plans," he went on, speaking fast. "Our schedule has us changing over to high-acceleration mode on the seventh of January. You know better than I how that takes two or three days of preliminary work by your gang and considerable upsetting of everybody else's routine. Well, somehow the flight planners forgot that the sixth is important in West European tradition. Twelfth Night, the Eve of the Three Holy Kings, call it what you will, it climaxes the merrymaking part of the holidays. Last year celebrations were so riotous that nobody thought about it. But I learn that this year a final feast and dance, with the old rituals, is being talked of, as some­thing that would be pleasant if only it were possible. Think what such a reminder of our origins can do to help morale. The skipper andl wish you'd check the feasibility of postpon­ing high acceleration a few days." "Yes, yes, I will look into it." Fedoroff urged Reymont toward the open door. "Tomorrow, please—" He was too late. Ingrid Lindgren came around its edge. She was in uniform, having hurried up from the bridge when her watch ended. "Gud!" broke from her. She stopped dead. "Why, why, Lindgren," Fedoroff said frantically, "what brings you here?" Reymont had sucked in a single breath. Every expression went out of his face. He stood moveless, except that his fists clenched till nails dug into palms and skin stretched white across knuckles. A new carol began. Lindgren looked back and forth, between the men. Her 53 own features were drained of blood. Abruptly, though, she straightened and said: "No, Boris. We'll not lie." 4
