Unfinished Symphony

by Rick Cook & Peter L. Manly

The eternal storms raged below, churning the clouds into cyclones big enough to swallow the Earth entire. Even here, thousands of miles above the melted-ice-cream swirl of the planet, other storms raged, filling space with a hash of radio noise and a sleet of charged particles.

The visitor sailed on, an untroubled tiny speck against star-scattered space and the light show of the atmosphere alike. It had traveled a long and circuitous path from its source, flung out from Earth by a combination of puny rockets and the massive forces of gravity. For five years it had caromed about the inner Solar System, banking off the gravity fields of the Sun and Earth like a well-played shot in a game of cosmic pool. Now after all the waiting, the planning, the improvising—after hopes and dreams and careers built upon it, it was ready to do the job it was designed for.

The spacecraft had not made the trip unscathed. The main antenna stood partially unfurled aind crumpled like a broken butterfly’s wing, useless victim of a mischance in space, millions of miles from any hand to tug it gently open.

Yet Galileo was not alone. Another man-made object flew in loose formation with it. Until five months ago it had been part of Galileo in its long journey through the Solar System. Then, on command, the atmospheric probe had detached itself and drifted away Where the rest of the craft was lumpy with antennas and booms and other projections in cheerful disregard for considerations of streamlining, this piece was as smooth and curved as a stream-worn pebble. It was designed to plunge into Jupiter’s atmosphere and bring back news of conditions never before experienced by humans or their creations.

Behind them, above them, and below them loomed the fiery bulk of Jupiter, banded and braided and twisted in a thousand shades of orange and red and yellow and white.

The spacecraft were as incapable of being awed by the planet’s size as they were of being impressed by its beauty. Months from now, after the probe had transmitted information back to the orbiter and it had been forwarded bit by bit to Earth to be assembled and interpreted, then perhaps the humans who created the craft would be awed or impressed. But that was utterly beyond Galileo’s capabilities.

With a puff of gas from thrusters, the Galileo orbiter took a slightly different course from its companion, one calculated to just miss the planet. The companion would not miss at all. Indeed, it was not designed to miss. Its job was to dive into Jupiter’s atmosphere and send back word of what it found.

The probe’s builders had considered carefully, weighing the desire for information against mass, communications bandwidth, and a hundred other factors before settling on just six instruments to collect data in the hour or so before the device was crushed to extinction in the depths of the massive Jovian atmosphere. Six instruments to extract the maximum possible amount of information given the conditions the designers expected the probe to encounter.

And no one on Earth had a clue as to how wrong they were.

“Storm up ahead.” The Geek broke into the strained silence.

Ensign was well aware of the towering, roiling mass of lemon-yellow clouds several thousand wing lengths beyond. But he was glad for anything that broke the mood.

“It will be an active one,” he sang out in the middle frequencies. “A lot of lightning.”

“My skin is tingling already,” The Geek agreed. “We’ll need to steer well clear of it.”

Melody, the third surviving member of the Bach Choir, snorted on several selected frequencies to show she understood her pod-mates’ ploy all too well and wasn’t—quite—ready to oblige. The result shivered Ensign’s hearing membranes, but he took it as a good sign.

“Rich feeding to come, though,” The Geek sang judiciously. “A storm that big will bring up plenty of plankton.”

What The Geek actually said was considerably more complex. The speech of creatures who can talk and listen on a hundred or so frequencies simultaneously naturally carries much more information than any human language. Besides the banal comment on the weather, The Geek had expressed his people’s truism that change is eternal and that bad times often unfolded into good. He had added a certain amount of onomatopoeia for comic effect to show he said it in good spirits and, perhaps most importantly, it chided Melody for her attitude.

Melody snorted again, less forcefully this time.

The three soared in a loose triangular formation perhaps a hundred wing lengths above the yellow-and-cream cloud tops. Their manta bodies were buoyed by their internal hydrogen chambers and propelled by flapping their enormous wingtips. Each member of the pod would have covered most of a city block on Earth, but none of the High Folk could have survived an instant s exposure to Earth conditions.

All around them plankton welled up from the clouds below, growing and blossoming in the weak sunlight. The three had deployed feeding scoops and opened the gills along their massive flanks, forcing Jupiter’s atmosphere through their bodies and straining out the nourishing plankton.

Melody trilled a bell-like chime on a hundred frequencies at once. “Listen,” she sang with ringing overtones to remind the others of her singing abilities, “I know we have to have more members to be complete. But the Bach Choir is—was—the finest singers in our whole cloud belt. Snow has no clear voice and little musical imagination.”

“We also need singers who understand the songs they sing,” The Geek replied. “Snow already knows many of Old Simon’s songs of astronomy and computation. More, she will be able to use them as he did to predict the motions of the Heavens—she can already foretell moonshadows so Gatherings can take place.”

“She is barely old enough to leave her birth pod,” Ensign added. “She will mature.”

“But will she develop? She shows no sign of it. We need singers.”

“We also need memory,” Ensign sang back. “She can give us that ”

Ensign hefted the weight of his own memories—literally. Clinging to his flanks and body were dozens of remoras, torpedo-shaped symbiotes whose talent was remembering. When the pod had been shattered in Skyfall of multiple comet strikes, he and the other survivors had acquired many of the songs and memories of those lost.

“Flashing eyes and a pretty set of wingtips, you mean,” Melody retorted in mock derision. “Memory yes, but we need real singers if we are to be great again.”

“Besides,” The Geek said quietly, “we all lost some of our hearing in Skyfall. Others will sing more sweetly—but we have most of the memories and ancient knowledge from those who perished.”

*Someone finally said it,* Ensign thought. The thing they had been dancing around, not-quite-ignoring, ever since their harrowing dash to safety, away from the cloud bands hammered by comet strikes. The shockwaves had killed many of their pod mates, those who hadn’t elected to stay behind in the south or who had not been taken by sharks on that terrible journey. And the three survivors had not passed unscathed. None of them would ever be the singers they had been before Teacher warned them of Skyfall and led them North. Ensign wondered if the pod could even continue as a true choir.

“All the more reason to recruit only the best singers,” Melody trilled stubbornly. But Ensign could see her heart wasn’t in it any more.

Ensign sighed, wondering how he could keep his bickering pod mates together, much less expand the group. They needed at least six more of the High Folk to sustain a functioning pod and that meant recruiting from other pods here in this alien place. He gazed at the young apprentice Snow, discreetly grazing out of earshot while they debated her fate. So young, he thought, so very young.

“We still have more remoras than we can easily carry,” The Geek sang on. “Snow can carry them and she can harmonize to the technical knowledge we barely understand.”

Melody remained silent, a sign that she disagreed but would not further object.

Looking at her, Ensign felt more than a twinge of sympathy. Before Skyfall the Bach Choir had been the most renowned singers in their entire cloud band.

The Geek called out to Snow, “Come join us, fly in the gentle wake of our pod.”

“I come.” Snow’s response sounded as a single, clear note. She had never sung so well before, Ensign thought. Perhaps the new member of the Bach Choir was a promising vocal choice after all.

Suzanne Quinlan—Dr. Suzanne Quinlan, she reminded herself—really had no business in the Deep Space Network control room. But she was there because in a few hours the Galileo probe would plunge into Jupiter.

Not that you could tell from the control room. The two consoles were dark, the desks appeared unlittered and the only people in the room were herself and F. Gary Rhine, who appeared engrossed in some kind of equipment check.

“Control room” was a misnomer for Galileo. The controlling was done by the computer on the spacecraft. Even at the speed of light it was nearly an hour from Earth to Jupiter, far too much lag to actually control anything directly. Nor would there be a flood of data, instantly translated into pictures. With the high-gain antenna useless, the data information would crawl back to Earth over the next weeks and months.

The control room was not manned because it didn’t need to be. It was still early morning and the probe would not penetrate Jupiter’s atmosphere until mid-afternoon. Rhine was there because he had work to do. Suzanne was there because, well, because it seemed right somehow that she be in this place. In a way this was what she had struggled through graduate school for, why she had labored over her dissertation and fought the growing disillusionment as she came to understand what a Ph.D in planetary science was really worth. In a way it was keeping faith with the promise implicit in all those magazines with the bright covers her father had carefully stored in the basement. Whenever she thought of that she remembered the rainy afternoons with the damp creeping into the basement and the woody smell of old paper in her hands.

It would have been better if there had been someone to share it with, but The Rhino’s reputation and air of fierce concentration didn’t encourage casual conversation.

The phone shattered the stillness and made her jump. Without thinking, she picked it up.

“DSN Control, Dr. Quinlan speaking.”

“Is this the Deep Space Network?” asked a nasal voice.

“Yes.”

“White House operator. Hold for a call from the vice-president’s office.” Suzanne looked around frantically for someone to hand the phone to, but Rhine kept his back to her as he fiddled with his instruments.

“Hello?” The voice didn’t sound anything like it did on television. “Terwiliker here. I need to speak to whoever’s in charge.”

“What?”

“Claude Terwiliker, special assistant to the office of the vice-president. Who’s this?”

Suzanne assumed her best tone of authority, “This is Doctor Quinlan. How may I help you?”

“We need a statement about that probe that landed on Jupiter. Also some pictures.”

Suzanne’s jaw dropped. “But—”

“Look, honey, let me talk to someone who knows what’s going on. OK?”

Suzanne colored to the roots of her hair. Before she could say anything else, Gary Rhine reached over her shoulder and slammed the speakerphone on with a swipe of his hairy paw. “Who the hell is this?”

“This is Terwiliker, special assistant to the office of the vice-president of the United States. Who’s this?”

“This is F. Gary Rhine.”

“Well, Dr. Rhine…

The Rhino frowned so deeply that his bushy salt-and-pepper eyebrows nearly met in the center of his forehead. “Mr. Rhine,” he growled. “Now what do you want?”

A brief pause. “The Vice-President needs photos of the surface of Jupiter from that spacecraft, ah Galileo?, for his speech tomorrow.”

Rhine expelled breath between clenched teeth. “Did you get the briefing package our flacks sent you?”

“The Vice-President needs the very latest,” Terwiliker insisted.

“Did you read what you’ve got?” Another hesitation then the voice firmed. “This is getting nowhere. Put your supervisor on.”

“Son, it’s just after six a.m. here. I’m the closest thing to a supervisor you’re gonna get. Now, did you read that stuff?”

“Well…”

“Because if you had,” The Rhino roared, “you’d know the damned data isn’t going to be available for weeks—thanks to the damned antenna that jammed because you damned Beltway idiots wouldn’t authorize a damned high-energy launch. You’d also know that even when the damn data does come limping through there won’t be any damned pictures because the damn probe doesn’t carry a damned camera.” He got all that out without taking breath. In spite of Suzanne’s terror she was impressed.

“Hey, don’t get upset. I’m only doing my job. The Vice-President has a press conference this afternoon and he wants to be able to say something about the program.”

“Tell him it’s on schedule.”

“OK. I guess that’s better than nothing!” The line went dead.

Suzanne finally managed to get her jaw closed as The Rhino reached over and slapped the speakerphone off. “God,” he growled, rolling his eyes upwards, “I love this job.”

“Was that wise?” Suzanne quavered.

“No, that was a bureaucrat. Worse, a political appointee bureaucrat. They’re not even sentient by any reasonable measure.”

“I mean, can’t he retaliate?”

The Rhino snorted explosively. “And let people know he was ass enough to call in the first place? Not likely. He’ll keep his mouth shut and just hate me quietly.” He grinned. “It’ll be good for his scum-sucking little soul.”

“I can’t believe he thought Jupiter had a solid surface,” she said, still shaken. “Not to mention that he didn’t know it will take signals nearly an hour to reach us.”

“Where bureaucrats are concerned, believe anything. Except intelligence, Mzz Quinlan,” he dragged it out like a buzzing bee.

“Doctor,” Suzanne muttered.

“I beg your pardon?”

“It’s doctor,” she said more distinctly. “Doctor Quinlan.”

“Don’t worry,” The Rhino said cheerfully. “I won’t hold it against you.” With that, he turned back to whatever it was he had been doing.

Galileo swung close to Jupiter, listening to the radio hiss, tasting the stream of particles tossed off by its moons and trapped in its magnetosphere. It sped above the dusty ring plane. Far below, the probe drifted ever-faster toward the planet, oblivious of time and travel and its eventual fate.

If Galileo wasn’t intelligent enough to be awed by what was around it, the probe wasn’t even smart enough to be called automated. A two dollar oven timer had more smarts than the sequencing switch that was the closest it came to a brain. Only when the crushing deceleration of atmospheric entry actuated a simple sequencer, would the probe take any action.

That time was fast approaching. The probe slid down the gravity well towards Jupiter at ever-greater velocity. The tenuous outer edges of the planet’s atmosphere began to take hold, tentatively at first and then ever more firmly as it grew thicker and stronger. Invisible fingers of gas tore at it, and the heat shield began to glow from the impact of the gas molecules.

The heat shield sprang away and the parachute streamed out behind. Then the radio transmitter began to broadcast the readings of six sensors, verbatim. Swinging gently under its parachute, the probe began its oneway descent into the clouds of Jupiter.

Ensign browsed on and watched Melody and Snow, grazing while practicing a simple duet. The Geek angled over and hummed quietly, “Looks like Melody has accepted her”

Ensign bobbed agreement. “A good start. But we need more members.”

“They’ll come—in time ” His tone changed. “Shark, low and to the right.”

Ensign’s body tensed as he saw the small, dark torpedo shape dimly through the clouds and relaxed again when he saw that they were beyond its range. The predators of the clouds often followed the plankton swells in hope one of the High Folk would be hungry enough or foolish enough to graze the richer fields at the very cloud tops. Ensign sent a low frequency warning to Melody and Snow. They acknowledged on the same frequency without interrupting their song.

The Geek said, almost casually, “Snow says she knows of a large pod in the east that would probably be willing to share members.”

“Oh? Does she know any of them personally?”

“No, only that the pod is ready to split. They deplete the plankton fields too fast and must constantly move.”

Ensign nodded. “Wise choice. Especially if there are calves. The constant travel saps their strength and they grow up weak. Perhaps we will drift eastward for a while.”

“SKYFALL!” Melody’s hysterical warning carried secondary tones indicating danger from the south.

Ensign used his upper eyes to find a bright white object arcing toward them while his lower eyes searched the clouds for a place to run—but a second shark appeared down in the clouds. Within seconds it became obvious that the piece of the sky falling near them was nowhere near the size or speed of a devastating comet. Indeed, as it came lower it dimmed to red and then a piece broke off. “Relax—it is a small skyfall. No danger. Just stay away from it.” Ensign had heard stories after the last Skyfall of small, hard solid things falling with the comet—stones that could pierce the soft tissues of the High Folk more easily than a shark’s jaws.

Then a long, dark streamer spun out behind the thing. Ensign thought it the strangest thing he’d ever seen in his life—until he saw the streamer blossom into a circular canopy attached to the object by sinews. It slowed greatly in its descent and swung back and forth below a billowing arc.

Suzanne Quinlan watched the data stream carefully on her monitor. Normally, sitting watch in the Deep Space Network Control Room was about as exciting as watching paint dry. This afternoon was no different. NASA’s large dish antennas scattered across the globe regularly communicated with a handful of interplanetary craft all over local space—and a few which had left the Solar System entirely. Her job was to make sure all the pieces of equipment—antennas, receivers, data recorders, communications links—and the people who operated them, followed a complex and ever-changing schedule.

Forty minutes ago the Galileo spacecraft had started a scheduled data transmission. The Earth-bound antenna it sought was still transmitting instructions to a satellite orbiting far above the south pole of the Sun. Just before Galileo’s message reached Earth, the antenna, located in Australia, swung around to hear it.

“Anything new?”

Suzanne started at the voice, and looked up to see F. Gary Rhine standing behind her.

“We’ve got some data.” She hesitated. “How was the administrative meeting?”

Rhine pulled a chair up and sat on it backwards. “If I told you it was stirring and inspiring would you believe me?” She didn’t respond as she searched the data stream for housekeeping bits that marked off blocks of data.

“If I can just hold on for another eight months of this equine excrement,” Rhine continued in his usual growl, “I can retire. Now they say we have a new performance review procedure we all have to go through.”

Suzanne looked at him out of the corner of her eye, not quite sure what to make of her new acquaintance. Rhine’s irascibility, explosive temper, and way of charging problems head-on had earned him the nickname of “Rhino.” She’d heard the water cooler gossip that he knew where every body and skeleton in all of JPL was buried. Supposedly he had started his career playing with V2s at White Sands in the early ’50s, and had spent all his life working with rockets and spacecraft. He was one of the few who’d lasted through the decades of budget cuts, killed programs, layoffs and program reorganizations. She decided she rather admired him, in spite of the fact that he made her profoundly uncomfortable.

“There it is!”

“What?”

“Memory allocations!” Suzanne pointed to the screen. “These blocks are probe data. Looks like we got a good chunk of data.”

F. Gary Rhine sighed. “Well, at least something went right today.”

It was Suzanne’s turn to snort. “All we know for sure is the probe data’s been stored in these memory blocks—it may all be incomprehensible garbage, but at least it’s duly recorded incomprehensible garbage.”

“Little cynical this morning?”

Suzanne sighed. “I guess.” Then on impulse she added: “I mean it’s exciting and everything, but it’s not the way I thought it would be. There’s all this trivial junk—like performance review meetings—and so little of the important stuff.”

“There’s damn little of the important stuff any more,” the older man told her. “You want my advice? Get out and go do something else.”

Suzanne grimaced. “There’s not much you can do with a Ph.D in planetology. But what about you?”

The Rhino shook his head. “I’m not as valuable as you might think. Most of this place runs on ’60s and ’70s technology, years behind the commercial stuff. I’m not so much a technical chief as I am curator of a communications museum.” Then the little-boy grin. “Besides, I’m sticking around to see what happens next.”

What next? Ensign thought as the strange thing came lazily down, borne slightly east by the prevailing winds. First Sky fall and now this.

The Geek watched the strange object drift toward them. “Is it alive?”

“It’s moving,” Melody offered.

Snow slipped beneath it to use her upper eyes. “It swings rhythmically.” She ventured a song of greeting. The thing remained silent.

The Geek moved in, “tasting” the probe with beams of sound. The upper round canopy was a membrane of some sort, but the lower section was unlike anything he had ever seen.

“It reflects,” he sang in wonder. “The lower part reflects almost everything.”

Even from his distance and angle Ensign could feel the reflections of The Geek’s song. That made him even more wary. Everything in the High Folk’s world reflected sound, but imperfectly. A probe of the right frequency told you something about the inner structure of things. But this object was reflecting everything from its surface.

For the moment he ignored the membrane as being more-or-less familiar and concentrated on the lower part. The small sphere wasn’t quite smooth. It had crisp markings in regular circles and lines. He compared it to the mottled skins of his own folk, sharks and plankton. A ray of sunlight glinted off the shiny surface, a phenomenon he’d seen only when looking into the eyes of others. “It’s smooth. Very smooth. I don’t see how anything would grow up like this!”

“It’s so hot,” Snow said.

The High Folk’s infrared detectors were not nearly as sophisticated as their natural sonar or their eyes, but it was obvious this thing was much hotter than the surrounding air. Even the living things of the cloud depths didn’t get this hot.

Ensign turned toward it. “Dead things fall, living things fly.” He eyed the mysterious object suspiciously, noting that the edges of the upper part fluttered in the breeze. “Keep your distance—it may be some kind of predator…”

Ensign climbed to gain a dominant position over whatever it was.

“Where does plankton like this grow?” Snow asked her more experienced pod mates.

Sky seed? It was a logical assumption. There were certain kinds of plankton that grew sails or drogues to better reap the rich energy harvest of the sunlight. But it didn’t feel right to Ensign. Plankton were tiny and soft. This thing was larger and its body appeared disturbingly hard.

Above the clouds there were only the High Folk, sharks and plankton of many different kinds. Most of Jupiter’s vast and complicated ecology was down in the cloud seas and known to the High Folk only as humans knew the depths of their own oceans. Sighting new kinds of life was rare for the High Folk, but it did happen.

“How do you know it grew?” Melody trilled. “This comes from the sky and who knows how things form there?”

“Keep away from it,” Ensign called again. But the fascination felt too much and all of them eased closer.

Snow slid out from under the thing and gained altitude, coming abreast of it. “Maybe somebody made it,” she offered.

The Geek snorted in derision, “You can make music and ideas—you can’t make things!” He glided closer.

“I told you to keep your distance.” Ensign called sharply. “Snow, you’re also too close.” He turned to pass over the ballooning canopy, examining its texture and colors with his lower eyes. Suddenly his tingle sense came alive. A massive lightning strike was building to the east.

“LIGHTNING—BREAK WEST!”

As one, the pod sheared away. The response was so instinctive it was several seconds before any of them realized there were no clouds to the east to generate lightning.

Ensign felt foolish for calling a false alarm. Then he realized that the tingling he’d felt wasn’t the usual hash of static but rather something alien, regular—like a song sung by lightning.

This was even stranger. The High Folk could stimulate each others’ tingle sense, but only at very close range. It was a calf’s trick to sneak up on an adult and fake a lightning warning to watch the adult break away. But that was a fluke ability, a nearly useless side effect of the sense that kept the High Folk from flying into areas of high electrical potential where their mere presence could trigger a shattering lightning bolt. Why could this thing invoke the tingle sense?

Snow’s inarticulate cry jerked him out of his reverie.

Snow was tangled in the Star Seed’s sinews, its sail billowed out over her wing and the hard object hung below it. When he’d ordered the pod to turn, he had inadvertently directed the newest member of the group directly into the strange object. Snow floated frozen, terror in her eyes. Ensign asked, “Snow, are you all right? Is it burning hot?”

Snow’s voices came ragged and panicky. “I—-feel—lightning—warnings—from—everywhere!”

Gary Rhine sipped his coffee and watched the traffic stream by the coffee shop. His turquoise-and-silver bolo tie and white short-sleeved shirt barely met the standards for office dress. His sport coat hung on a hook in his cubicle, still wrapped in plastic from the cleaners.

The late afternoon meeting was as unofficial as the setting. No one in the PR office would have dreamed of letting The Rhino near the press and Rhine held the media in general in contempt. But then Larry Collins had officially turned over coverage of planetary encounters to younger colleagues at the bureau after Voyager passed Neptune. Although he would file a color story for the wires, this was more a meeting of old friends.

“The probe’s radio antenna points upward and broadcasts a conical beam to Galileo overhead,” Rhine explained as he marked the napkin with bold scrawls of a felt-tipped pen. “We timed the probe’s entry so the spacecraft will be in the cone at the right time.” Another series of circles, slashes and heavy dotted lines bleeding black and fuzzy into the napkin. “The Earth is right at the edge of the beam and the National Radio Astronomy Observatory’s Very Long Baseline Array in Socorro, New Mexico, listened for the signals during the probe mission. They say they got the signal.”

He pulled the napkin back for some more scrawls. “Now our next job will be to see if we can pull a Doppler signal out of those data and determine the horizontal drift velocity of the probe, which will tell us something about Jupiter’s wind strength. If we’re lucky we may get a vertical velocity, too. That could be correlated with the altitude data that’s supposed to be transmitted from Galileo in a few days.” He paused. “If we re real lucky, we may even be able to decode the modulation and obtain raw probe data.”

“So the mission’s a success?” Collins asked as he studied Rhine’s handiwork.

Rhine shrugged. “So far. Or it was when I left. God knows how it’s managed to fuck up while we’ve been sitting here drinking coffee.”

Larry lifted his white eyebrows in mock surprise. “Cynical, ain’t we?”

“Let’s just say I’m a devout believer in Murphy’s law.” Another sip of coffee and then a broad grin. “Hell, I knew Colonel Murphy back at White Sands.”

“So you’ve told me. And as I recall you always thought he was an optimist.”

Gary chuckled. “Sonofabitch was.” Then he glanced at his watch. “Well, I gotta get back and massage some electrons.”

Larry picked up the check and stood up. “Yeah, I suppose I should go do something productive too. Like write something about this that maybe someone, somewhere will want to read. You got any hot surprises for me about the mission?”

The engineer grinned like a little boy. “Oh, lots of them. We just don’t know what they are yet.”

“So the only surprise would be no surprise, eh?”

“Larry,” Rhine said completely sincerely—and utterly incorrectly— “the only thing that could surprise me is if the probe mission went off perfectly.”

The Geek hovered over the Sky Seed, at once fascinated by its song and afraid of its signals as lightning warnings. Melody circled warily, her shadow falling on the tiny sphere at the bottom. Suddenly The Geek exclaimed, “The song changed—it definitely changed just for a moment there!” Melody circled back, eyeing the sphere closely.

When her shadow covered the Sky Seed again, The Geek sang out that the song had changed a second time. “It responds to you, Melody! It is alive!”

She shuddered slightly, moving away from the thing, but The Geek pressed even closer. Meanwhile Snow was slimmed to a fleeing shape and maintaining her altitude with jerky little motions of her wingtips.

Ensign lay off to her side and sent her a constant stream of reassurance. Her plunge away from the non-existent lighting had left several of the shroud lines tangled around her body and the canopy draped over a wing. She might be able to free herself by violent maneuvering, but Ensign was afraid that would cause the searing hot Sky Seed to touch her with disastrous consequences.

The Geek was still experimenting with casting shadows on the thing to hear its song change. Occasionally he tried to speak to it, but it would not respond on any frequency. Melody hovered off to the other side, trying to encourage Snow without getting too close to the thing.

“Snow,” Ensign sang, “You need more buoyancy. We’re getting a little too close to the clouds. So just relax a little and let your body expand. Can you do that?” Snow shivered, a gesture that might have been agreement. “That’s good. Now just a little bit more. OK? A little more. You’re doing fine.”

“Come on,” Melody chimed in in multi-part harmony with the deep overtones of a mother calling her calf. “Come on, Snow, you can do it. Just a little more. Just a little more.”

With his lower eyes Ensign kept scanning the clouds below. He couldn’t see any sharks but he knew they were down there and probably keenly aware of the the group above them. They were still out of range of a shark’s lunge, but they wouldn’t be much longer. If they couldn’t get Snow to expand soon they’d have to face the sharks in the clouds.

Gradually, with a stream of encouragement from all three of them, Snow started to relax and expand. Once or twice she made convulsive, jerky movements of her wingtips as if she wanted to fly for all she was worth, or worse yet, jet upward on a stream of expended hydrogen. But flapping might have tangled her more in the thing and expending hydrogen would leave her less buoyant.

Then slowly, very slowly, Snow began to rise again. Ensign and Melody stayed beside her, encouraging her and talking to her to keep her relaxed. The Geek drifted back and started examining the thing trailing at the end of the lines.

“It’s getting weaker,” he reported to the others. “It isn’t singing as loudly.” He paused. “I think it’s dying.”

“Keep listening,” Ensign told him. “Let us know if it dies completely” He hoped the thing would relax its grip in death and release Snow. If it didn’t they would have to take more drastic measures.

“Weaker, weaker,” The Geek sang. “Very much weaker. Now, nothing. No song at all.”

Ensign studied the thing with probes of sound. It was much cooler than it had been, but its structure hadn’t changed at all and it showed no sign of releasing Snow.

“All right, we ll have to get it off her,” Ensign sang. He sent a quick message to his remoras, to see if any of them had any songs that dealt with a situation like this. But the only songs about contact between High Folk the remoras carried involved sexual techniques, a kind of Jovian Kama Sutra that wasn’t much help here.

“Snow,” Ensign sang, “bank right. Please forgive me, but I am going to come above and behind you in mating position to try to work it off with my wingtips. Will you trust me for this?”

Again Snow gave a frightened bob of assent.

Ensign maneuvered above and behind the young female, fighting down the arousal the position produced. With Snow banking toward the parachute and probe, part of the canopy slid off her wingtip and instantly billowed out in the hurricane force wind.

The drag threw Snow off balance and Ensign banked desperately to avoid crashing into her. He slid by her, batting at the canopy and shroud lines with a wingtip, trying to scrape them off. Snow turned belly-on to the wind as the canopy’s drag increased and then she was free, the dead thing falling away under its fouled, partially expanded canopy, and dropping into the clouds below. Ensign wondered briefly what the sharks would make of the Sky Seed.

The Sun had long since settled into the Pacific Ocean in a dirty orange smear and it was full night in California. But Rhine and Ed Steveberg, an engineer on loan from the VLA, were hip-pocket deep in the first big surprise of the day and oblivious to the time. Steveberg was young, thin, and blond with a slightly squashed beak of a nose and a bit of a contact squint. Just now his scowl was as deep as Rhine’s.

Beyond the doors of the conference room a carefully concealed air of genteel panic was spreading through the probe team. By tomorrow morning, when most of the staff came in, the panic was likely to be a lot less genteel. Rhine and Steveberg weren’t panicked, but they weren’t real happy either.

“So,” the Rhino growled, “we got two major anomalies and a possible probe glitch: First, the probe signal has no vertical velocity component and apparently no horizontal component either. Second, you think something intermittently blocked the radio beam.” He glanced up. “Let’s go over that again.”

Steveberg tapped the printout with his pen. Everyone else had called the information up on screens, but the Rhino felt more comfortable with printouts. “We see gaps in the data where the signal fades for several seconds at a time. It’s not a problem with the receivers here on Earth because it shows up in all the Earth antennas simultaneously—something happened out there at Jupiter.”

“Intermittent transmitter failure?”

“No, for two reasons. First, when you first turn the transmitter on, it hunts in frequency for a second or so. The frequency of the probe signal is steady—ergo, something blocked it. Secondly, the signal doesn’t just snap off and on—it fades out and in.”

Rhine rubbed his chin and spread his lips in a mirthless smile. He loved a good technical mystery—it made the job worth doing. “How about if the probe were swinging below the parachute? The transmitter antenna is aimed up the shroud lines.”

Steveberg frowned. “If it’s oscillating under the chute, I’d expect a regular fading and return.” He gestured toward the signal history. “This looks pretty much random and intermittent.”

Rhine looked at the displays, glanced at the data summary printouts and took note of the two other engineers assigned to the task. His expression and demeanor were as serious as the occasion demanded, but inside he was grinning and rubbing his hands with glee. He knew he wouldn’t get any sleep tonight, but he relished the detective work ahead, was glad he’d been given the resources and people to get the job done. They’d handed him an interesting task. The fact that a dozen other teams were working on the same problem all around the world didn’t detract one whit from the excitement.

“God,” he muttered under his breath, “I love this job!”

Fourteen hours after the probe stopped transmitting, Galileo approach ed the edge of Jupiter’s disk as seen from Earth. For a while it would be out of touch, hidden by the bulk of this alien world. Just as it started behind the planet, as the image of Earth shimmered and blurred under the effects of the Jovian atmosphere, it broadcast a data stream to eager antennas on the Home Planet. Scientists would note the signal’s absorption and attempt to discern the density and perhaps the composition of gasses in the higher reaches of Jupiter’s clouds.

“Shit,” said F. Gary Rhine as he looked at the latest data reduction from the Galileo probe. The number crunchers had used the whole night to crank on the probe data and they’d gotten a preliminary flight path profile. What the computers had churned out wasn’t comforting.

“I don’t suppose the damn altimeter could have gotten stuck? ”

Ed Steveberg shrugged. “I don’t see how, but that’s Instrumentation’s pigeon.”

“OK,” Rhine said, looking at the group clustered around the table, “I will grant you the circumstances are suspicious as hell. According to our tests everything in the comm pathway is functioning perfectly.” A raised eyebrow told them how likely Rhine thought that was. “But so far we can’t find anything that would cover the facts.”

Another senior engineer stabbed a finger down on the graph of the probe’s path. “Well, the damn thing didn’t just stop halfway down to take a rest.”

“Bad weather?” someone else suggested. “The probe might have gotten caught in an updraft.”

“That would take one hell of an updraft.”

“So? How much do we really know about the conditions in Jupiter ’s upper atmosphere?”

“Obviously not nearly as much as we thought we did. OK, so assume it’s an updraft—a hurricane blowing straight up—why did the signal keep fading?”

“That’s easy,” Steveberg said. “The probe was getting tossed around and it kept losing alignment.”

The Rhino grunted. “That doesn’t feel right. It looks more like something was blocking the signal.”

“What? It was hung up on a tree limb and the branches kept getting in the way or something?”

F. Gary Rhine cocked a furry eyebrow. “Or something.” He scowled down at the latest data. Normally troubleshooting a complex system involves formulating and testing hypotheses. And normally the problem is eliminating the hypotheses down to a testable number. Here they had every engineer’s nightmare. There were simply no testable hypotheses that could explain what had happened in terms of a communications malfunction. Without theories to proceed on the team was just spinning its wheels. Logically that meant the problem was in some other team’s bailiwick, but Rhine knew the other teams were also coming up empty.

He sighed. “OK, let’s go back to the assumption that there was something wrong in the chain of communications. That’s what we’re paid to do, not worry about the weather on Jupiter. Let’s go over it again and we’ll meet in twenty-four hours. Maybe by that time we’ll have some better information.”

Ensign watched the Sun set. Snow hung on his flank like a calf, silent and withdrawn. For more than an hour she had been trapped by Sky Seed, terrorized by its song—or something like a song, he corrected himself—sung in the mode of a lightning warning.

Off to the side The Geek and Melody continued their argument. “I tell you it was alive! It responded to us. It sang!”

“But it didn’t sound like a song and it stopped later.” She paused for effect. “Living things don’t look like that—all hard and smooth and shiny.”

“Plankton don’t look like us and they’re alive. If you could have heard the song yourself—if you’d have flown above it—you’d know it was an intelligent message.”

Melody snorted, “I’ll stay as far away from such things as I can. Look at poor Snow—she croaks one-word responses since she managed to free herself from that thing.”

Ensign interrupted, “Are we ready for Evensong?” At each Sunset the pod prepared for a quieter, more introspective flight.

Suddenly Snow wailed, “It’s coming back! I can hear it!”

Ensign focused his tingle sense and found the signal, faint from the darkness and radio noise in the east. The tingle song was unmistakable but richer in variations. Not harmonic but faintly rhythmic. Snow sobbed.

“Yes! I can sense it, too! But it’s different—a more mature sound.”

Ensign tasted the song again. Normally the High Folk ignored the background noise in their tingle sense, filtered it out automatically without thinking. But by concentrating and bringing the crackling, hissing, popping hash of Jupiter’s natural RF emissions to consciousness he was able to pick out the strange singing.

If Snow hadn’t been sensitized to it by the Sky Seed I never would have noticed it, he thought as he strained his huge eyes for some indication of the singer.

Unseen to those below, Galileo passed beyond the limb of Jupiter, having beamed its message through the upper atmosphere. In about an hour the listeners on Earth would pick up its message and could begin to draw their conclusions about Jupiter. Meanwhile the Jovians were drawing their own conclusions about Galileo.

“That had to be an adult,” The Geek maintained. “The mature form of the Sky Seed.”

“Calling to its calf?” Melody wondered aloud.

“Perhaps.” Ensign tried to sound judicious, mature, and realized he wasn’t doing a very good job of it.

Snow wasn’t saying anything for pod consumption, just huddling close to Melody like a calf with its mother. Ensign strongly suspected Melody was sending a constant stream of high-frequency reassurance to the badly frightened youngster.

“So these things live above and they communicate by tingle sense.”

Ensign rippled a shrug. “Makes sense after a fashion. Our voices grow weaker as we climb higher and the pressure becomes less. Eventually the pressure must become so small voices can’t be heard. The sunlight is stronger up there so plankton can grow large.”

“But where is its calving ground?”

“Not here,” Ensign said. “We would have seen it otherwise. Perhaps it calves above.”

“Or maybe it calves in the layers below us and flies up into the sky to feed before returning to those lower layers.”

“That seems unlikely.”

“Then where is it from if not from the lower layers?”

“Here, let’s see if we can find a good candidate. Snow, please loan me the remoras with the songs of the sky.”

A half dozen remoras detached themselves from Snow and darted across the distance to Ensign’s side. There was a certain amount of wiggling and tickling as the newcomers settled in.

“Let’s begin with the ‘Song of the Wanderers.’ ” There was more wiggling and tickling as one of the remoras positioned itself over Ensign’s left dorsal earmouth and began to sing to the membrane. After an instant Ensign began to sing with the remora, transferring the information to his pod-mates.

Although the High Folk were by nature sound-oriented, the remoras’ memories could hold pictures as well. Now the little symbiote wove a complex story of the Wanderers through the sky and what the people of Jupiter knew of them.

The High Folks’s main eyes were more than two meters in diameter and they were backed by an elaborate neural image processing system. A Jovian’s “brain” wasn’t organized anything like a mammal’s, but roughly 80 percent of its central neural structure was given over to receiving, interpreting, and sending signals. For the High Folk planetary astronomy was a naked-eye proposition.

But not a very popular proposition. Except for solar eclipses of Jupiter’s moons, the High Folk paid little attention to what went on above them. However, among the remoras the Bach Choir carried were the remnants of those of Old Simon, the greatest of the Newcomb Pod, which had specialized in studying the skies for generations.

As the song wove on, Ensign, The Geek, Melody, and Snow were all entranced by the images forming before them. One by one the Wanderers spun out before them, as sharply and as clearly as generations of Jovian astronomers had managed to see them. As the first remora reached the limits of its memory, another took its place and another after that. Finally the “Song of the Wanderers” spun away into silence, leaving the images sharp in the minds of the pod members.

“The Second Wanderer!” Melody breathed. “It must be the Second Wanderer.”

The others bobbed agreement. The First Wanderer was a featureless mass and the Third Wanderer apparently had only one, mostly brick-red, cloud layer. But the Second Wanderer showed cloud layers and patterns very like the ones they flew above— if it weren’t for that disconcerting blue-green tinge to the lower layers.

“It seems logical,” Ensign said. “If these things have a calving ground in the sky it would be the Second Wanderer.”

“So we have been visited by a being from the Second Wanderer,” The Geek said slowly, “one who communicates by tingle sense.”

Actually he said much more than that. By his frequency choice and faintly dissonant chords, he expressed how such a story was likely to be received. Like most of his people The Geek was a pragmatist. This thing had happened, so no matter how unlikely it might be, it was so. Accepting the explanation was another matter.

“Offering such a story will not help our reputation,” Melody said at last. And, she did not have to add, it will make it harder to recruit more members.

Ensign damned himself for not seeing the implication earlier. The Bach Choir was new to this cloud band, their ways were somewhat alien and they needed to augment their number. No matter what their singing abilities they still lacked the prestige of an established pod. Like any intelligent species the High Folk understood rumors, tall tales, and downright lies, and like most intelligent species they were more likely to consign something completely outside their experience to one of those three causes than to accept it outright.

And there was no proof. The Sky Seed was gone into Jupiter’s murky depths and no others had been close enough to see their encounter. They had their memories and the word pictures they could draw, but that was all. And neither words nor memories encoded the theory they had developed.

“We don’t have to tell anyone,” Melody ventured at last.

They didn’t like that either. Among the High Folk information was for sharing. Withholding it was like withholding food.

“Perhaps someone else saw the Sky Seed,” Snow ventured.

“There was no one else close enough.”

“Then perhaps there will be another one soon.”

Melody snorted. “Have you ever seen one before? Do you even know of any songs about them?”

“Maybe we can call one to us,” Snow suggested.

“If they communicate by tingle sense perhaps we can talk to them,” The Geek said.

“How strong is your tingle sense?” Ensign asked. “That Sky Seed was easily as powerful as hundreds of High Folk.”

“So we get hundreds of High Folk to sing to the Second Wanderer with our tingle sense.”

“And how do we do that when we don’t tell them what we suspect?” Melody retorted. “We either tell them and damage ourselves—and perhaps still don’t convince enough High Folk to sing loudly enough—or we don’t tell and no one will see any sense in trying to sing with the tingle sense.”

No one said anything else. Ensign realized the entire pod was looking at him, waiting for his decision. Sky above, he thought bitterly, I love being pod leader!

Then the realization grew and finally burst in on him like full dawn on a clear day. There was a way!

“Let’s not be too hasty to broadcast the news.”

“So we do not speak of this thing, then.” There were overtones of disgust in The Geek’s voice.

“No,” Ensign thrummed slowly. “We don’t speak of it.”

“Associated Press, Collins.”

“What the bloody hell,” bellowed a familiar voice in his ear, “is this nonsense?”

Larry didn’t need clues to identify either the voice or the “ ‘nonsense.’ ” “Hi, Gary. Hey, I didn’t write it.”

“I can read a byline,” Rhine growled in his ear.

“Yeah, well he’s got this odd notion that if you don’t find what you expect to find the experiment is a failure.”

“Doesn’t know John F. Feces about research, does he?”

“I think his degree’s in sociology,” Collins agreed. “He’s got a master’s in journalism—which makes it worse because he won’t listen to anyone.”

“When the hell are you going to get some science reporters who know something about science? An ‘expensive failure,’ my ass!”

Collins leaned back in his swivel chair. “Well, you gotta admit you didn’t get the data you expected out of the probe.”

“We got data, dammit!”

“You mean you got a signal back that doesn’t tell you anything.”

“Wrong. It tells us a hell of a lot. It tells us Jupiter isn’t like what we thought it is.”

“You mean it’s got hurricanes blowing straight up?”

“I mean it’s got something.”

Collins pounced. “So the hurricane story isn’t completely accepted at JPL?”

“Only by the ones who can’t find their asses with both hands. I’ll grant you that’s a lot of them, but not everyone by a long shot.”

“OK Gary, what’s the alternative theory?”

“There are a bunch of them,” Rhine’s voice dropped almost to a mumble.

“Name three.”

“Later, Larry. When I get them sorted out.”

“Which one do you think is the most likely?”

There was an uncharacteristic pause on the other end of the line. “Larry,” the Rhino said at last, “you remember that saying about ‘not only is the universe stranger than we imagine it’s stranger than we can imagine’?”

Larry leaned forward eagerly. “Yeah?”

“Well,” Rhine drawled, “it’s even stranger than that.” With that he hung up.

All over Jupiter, High Folk were arranging themselves along the track of the eclipse, guided by the ancient songs of prediction. An eclipse, a Gathering at moonshadow, a place for pods to meet and celebrate their world as they knew it. Every place the moon’s shadow touched there would be High Folk beneath it to sing songs of welcome and praise. The inhabitants of Jupiter’s cloud tops couldn’t be said to worship the eclipse, but the mood came close.

Even from as high as he could comfortably fly, Ensign saw an endless river of High Folk, stretching from horizon to horizon along the path the moon’s shadow would take across the tops of the clouds. Though widely separated, they were tightly packed by the standards of the free-living High Folk. There were pods and family groups, and here and there a lone yearling or two cavorting above the clouds, temporarily safe from sharks.

Just like home, Ensign thought to himself, and then sobered when he realized that this cloud band was his home now.

He turned his attention back to his guests—senior pod leaders—older, puffier, and ill at ease this high. In the anarchic society of the High Folk this was as close to a government as you got, and right now they wanted his assurance.

“This is most unusual,” the central old one hummed out for perhaps the twentieth time. “Most unusual indeed.”

“I agree it is different,” Ensign said, “but I’m sure you will find it most satisfactory.”

That was putting it mildly. Ensign, Melody, The Geek, and even Snow had labored through the months since the Sky Seed—composing, arranging, polishing, testing new harmonies, tearing out part of what they had so painstakingly crafted and recomposing to produce what might be the Bach Choir’s master work.

“Has everyone received the song?” he asked.

“The remoras have been traded all through the band,” wheezed the oldster on the left. He was ancient enough that he had trouble controlling his gas cells and hence his shape. It could not be comfortable for him to be this high and Ensign was sure his membranes, inelastic with age, were being stretched painfully.

“Then it waits only the eclipse to begin,” Ensign told them. With his rear eyes he checked out the rest of his pod, clustered tightly and ready to begin their chase across the sky.

“Still,” the central oldster went on, “this is so, so different. Is this some Southern fashion?”

Ensign rippled his trailing edge in a manner that indicated non-specific agreement. “Somewhat.”

Snow bobbed to look skyward with her main eyes. wWe have perhaps one more day-tenth,” she sang out, “a little less perhaps.”

Ensign rippled agreement. In the weeks since she had joined them Snow had become surprisingly adept at the songs of prediction. That had been an important factor in the honor accorded them of leading all the pods in their new Song of Gathering.

All of the pods. Unlike most performance pieces this one had a chorus for all the celebrants at the gathering to join in. A most unusual chorus.

If their voices were not what they had been, the Bach Choir’s musical inventiveness was as great as ever. And they had labored over this song like nothing they had ever written before.

“We are ready then.” He bobbed respect to the elderly delegation. “If you will excuse me I must join my choir.”

Still muttering dubiously about these new innovations, but sighing with relief, the elders slid down toward the cloud tops to join their pods.

“Show time,” Ensign sang quietly to his pod mates. “Let’s make it good.” The others bobbed agreement and clustered around Ensign, humming, buzzing, droning and chiming as they tested their many voices and tuned their membranes to each other. Underneath it all came Snow’s metronome beat, counting down to the moment of eclipse.

“Threetwoone NOW,” and with that the Bach Choir tightened their membranes and burst out in the “Welcoming Song For Moonshadow.”

The first three phrases were for the Choir alone. Then, exactly on cue, the multitude spread out below them belled up in their part of the song.

Wingtip to wingtip, singing for all they were worth, the Bach Choir turned as one and began to race along the shadow’s path just as the first bit of the Sun began to dim. Below, the massed High Folk added their part to the great welling of sound.

Melody and Snow wove over and under each other on the high parts. The Geek and Ensign took the middle registers. The effect was somewhat odd. Most choirs had twice as many members as were left to the Bach Choir and had a better balance of voices. The quartet was especially weak in the low registers, a fact which the chorus helped to mask. Still it was impressive. Ensign felt a thrill as they glided above the singing masses, listening to them add their weight to the song.

And the sky went BZZZHMMbeep-beepbeepbeep, chorused the rest of the Gathering.

And the sky went BZZZHMMbeep-beepbeepbeep.

Although the idea of “singing” with the tingle sense was completely unfamiliar to the High Folk, they picked it up readily, singing the part just as the remoras had given it to them, down to the modulations in the tingle sense. They were aided by the fact that the part for the tingle sense was extremely simple, just turning the signal on and off at intervals.

The High Folk were experts at synchronizing their actions, even over distances where time delays became perceptible. The resulting song wasn’t perfectly in step, but it wasn’t far off either.

Individually the High Folk could radiate very little energy, a fraction of a milliwatt each. But there were thousands of them all along the path of the eclipse in this band. Together it was enough.

The Bach Choir chased the moonshadow as far as they could, singing all the while. But eventually it outran them and left them in the clear sunlight, surrounded by a congratulatory mob of High Folk.

“Magnificent performance,” an elder bubbled, surprisingly strong in the high registers. “I’ve never heard anything like it.”

“It was the chorus,” Ensign thrummed modestly. “It was all the High Folk together”

The Geek sidled close through the congratulatory throng.

“Now what?” he asked on a high, tight beam that only Ensign could hear.

Ensign continued to respond to the flood of congratulations, but he bobbed his body so his main eyes were focused directly skyward. “Now,” he beamed to The Geek, “it is up to the others.” If there are others.

“Gary, this is Ed Steveberg at the VLA.”

“Hey, Ed, How’s life in New Mexico?” F Gary Rhine swung his feet up on the desk and switched the phone to his other ear.

He could almost hear the VLA radio engineer’s frown. “Interesting—as in the ancient Chinese curse.”

Rhine chuckled. “Yah, we still haven’t made any progress on the Probe. Still looks like it stopped moving downward and something blocked its signals.”

Steveberg’s laugh sounded more like a bark. “That’s last month’s mystery. I’ve got a new little mystery for you. We aimed the antenna array at the orbiter yesterday to get a precision Doppler hack on it before the next orbital change maneuver.”

“Yeah?”

“Well, we got two signals back!”

Rhine thought for a moment. “Multipath reflection of the Orbiter’s transmission off some intervening surface like Jupiter’s rings?”

“Our first thought, but the weaker signal isn’t from the Orbiter—it’s from the probe!”

Gary didn’t say anything for a moment. A long moment. “The probe— the atmospheric probe?”

“The one and only! It has the framing pattern of radio data transmissions.”

“Um, the batteries were only good for a couple of hours.”

“Yep. And it gets curiouser and curiouser. I took a Doppler reading on the probe frequency and, over a period of several minutes, looked at motion at right angles to the beam.”

Rhine warmed to the analysis, “You’re assuming that the signal originates at or near the cloud tops…”

“That’s where we left it. Anyway, I got an accurate solution and can you guess what happened at that latitude and longitude just about the time the signals started?”

“I bet I’m about to find out.”

“The largest and longest solar eclipse as seen from Jupiter by the Galilean Moon Europa was going on right there!”

“Um, Ed, is that supposed.to have some significance for me? I’m not much of a planetary scientist.”

Steveberg laughed. “No, I just thought I’d brighten your otherwise mundane existence with a Class One Enigma.”

Rhine shied away from the mysterious part of the problem and attacked the one area of his specialty, “Have you decoded the probe’s signals?”

“So far, all we went for were the Doppler and position. We’ll let you know as soon as we have something.”

“Well, don’t diddle around with channels. Shoot me something as soon as you’ve got it, OK?”

“E-mail coming up,” Steveberg promised and then hung up.

Rhine hung up the phone slowly. For a long time he sat staring into his desk blotter as if deciphering the random ink stains and doodles.

Steveberg was even better than his word. Two days later he flew in from New Mexico with an attache case stuffed with data disks and printouts. He, Rhine, and the other members of the communications team spent several days going over them.

Their conclusions were surprisingly inconclusive.

“You know what’s wrong with this mess?” Rhine asked Steveberg over coffee in the cafeteria late in the afternoon of the second day.

“Yeah, it’s a mess.”

“Bullshit,” Rhine said without heat. “It’s what’s here and what’s not here. What’s here is the framing for the probe signal. That’s dead-nuts perfect. But what’s inside those frames is gibberish.”

“You mean noise?”

“No, gibberish. Noise is random. This stuff isn’t random, it just doesn’t make any sense.”

At the next table Suzanne Quinlan concentrated on her diet soda and tried very hard not to listen in.

“Distortion?”

Rhine cocked an eyebrow. “Which leaves the framing untouched?”

“Maybe there’s some kind of delay line down in the atmosphere that’s kept the signal echoing all this time.”

The Rhino snorted.

“Think about it,” Steveberg persisted, “If that’s what s happening you’d expect the paits of the signal that are constant, the framing, to be the most perfect because it’s the most often repeated. The other stuff, the contents, is more variable so it would be more likely to be scrambled. If you look you’ll see even the framing is a little fuzzy.”

“So what the hell is down there that acts like a delay line?”

“We don’t know yet. If it’s a point source it’s fairly far down into the atmosphere. Who knows what kind of weird structures are in there?”

“What if it’s coming from the cloud tops?” The Rhino interjected.

Steveberg thought for a minute. “Best thinking at the VIA is that it isn’t. If it was at the cloud tops it’s not a point source, more like a band following the shadow of the eclipse. Why?”

“Because that deep in the atmosphere you’re not likely to get any effect from the eclipse. You would on the cloud tops.”

“But that means you’ve got a radio source several thousand kilometers long on top of the clouds.”

“Anyway?” he went on, “it’s not true that you won’t get an effect from the eclipse down in the clouds. There are probably tidal effects, for example.”

The Rhino didn’t reply, but he didn’t look happy either.

F. Gary Rhine stayed late in his office that night, going over the data and fighting a growing conclusion.

“Oh shit,” he implored Murphy and whatever other deities might exist. “Don’t do this to me! In a few months I can retire. I’m too old for this.”

He recalled the debacle when British radio astronomers detected regular radio pulses. No, it wasn’t a message from Little Green Men, just an unknown astrophysical phenomenon.

Maybe some fool was spoofing him. It looked like one of those signal processing exercises where the instructors deliberately blanked part of the message. But if so it was a very elaborate spoof. In the weeks since the probe he had obtained originals of the data from all the observing stations and gone over it bit by bit.

Well hell, he wasn’t an astrophysicist. Let them explain it. Meanwhile, he only had a few more months until retirement. His windmill tilting days were well behind him.

Somehow that wasn’t comforting.

Suzanne Quinlan sipped coffee in her postage-stamp balcony and looked out over the parking lot to the brown hills beyond. It was twilight, but not dark enough to see the stars yet, and Jupiter wouldn’t rise for a while.

Something had happened out there. Something important, she knew, but what? What could possibly have caused the probe to act in that way?

The Rhino was right. This new signal wasn’t random, but it was gibberish, something that didn’t quite make sense, like a child’s babbling attempt to imitate his elder’s speech.

That led her back to the thought she’d been avoiding all day. What if there was some kind of purpose behind the repeat? Something out there to send the signal back?

Neat theory, it explained everything. It was also crazy. Suzanne had grown up reading science fiction. She had vicariously contacted a thousand alien races and now maybe, just maybe, she actually stood on the threshold of acting out her wildest dreams. The idea was so attractive she knew it had to be wrong.

It was also dangerous. She was in no position to advance a theory like that. She had no standing, no credibility and no tenure to protect her.

By nature Suzanne Quinlan was not confrontational. In graduate school she had perfected the fine art of getting along by going along, and above all by keeping her head down and avoiding negatives.

“If I even mention the possibility they’ll say it’s stress and send me home,” she muttered. After that she’d be lucky to get a job teaching astronomy at a junior college. Or maybe she could get a job on one of those TV astrology hotlines, foretelling the future on the basis of the voices from the stars.

She set the coffee cup down and realized she was hot and sticky from the smog and late afternoon Sun. A shower could take care of that, but nothing she knew could deal with the little itch that was growing in her brain.

“God, I love this job!” she muttered as he headed for the shower.

Another day, thought Suzanne Quinlan, another meeting.

The Anomaly Committee, as it was universally known, had been meeting regularly for months now, and rather to her initial surprise, Suzanne had found herself representing her group on it.

By now she understood perfectly well what was going on. The committee was purely symbolic—a collection of scapegoats designed to appease the eventual wrath of The Powers That Be. The probe was a failure and the politically skilled were disassociating themselves from the project before that sank in. The men and women at the very top were too closely connected to the project to have that luxury, and the people on the front line were too committed to disown their child. But at the middle and lower levels managers were oozing away like jellyfish, sucking the greenhorns and the lower level people in to fill the void. Clearly this was not going to be a shining spot on any one’s resume, especially the ones holding the ball when the news really broke.

For the principal investigators and the others at the top, it didn’t much matter. Their reputations could stand the strain and many of them were near retirement anyway. But the middle-level and lower people were a different story. Associating with the data analysis of the Jupiter probe might mean they’d end up teaching astronomy at the high school level. After weeks of being stuck in these meetings there was a part of Suzanne Quinlan that couldn’t see that as a bad thing.

Suzanne had found herself spending an average of one afternoon a week in a conference room with a collection of the old, the weak, the outmaneuvered, and the expendable. Although there were no place cards, they were ranked around the table by status with Dr. Smith, the chairman, at the head, flanked by Dr. Lewis and Prof. Van Meurs, and sifting down from there.

Down at the foot of the table, next to Suzanne Quinlan, sat F. Gary Rhine, in case someone wanted some details about the communications network. So far no one had.

As the committee members settled in, Suzanne concentrated on the scheduling data in the folder before her. There was nothing new there, but then there hadn’t been anything new in the last couple of weeks from anyone. They were simply going through the forms and everyone knew it. She noticed that perhaps one-third of the committee members were absent and damned the Catholic conscience that drove her to attend these stupid useless meetings.

After a few preliminaries, Dr. Smith opened the meeting for comments.

“The most likely hypothesis still appears to be a transmitter malfunction,” Dr. Lewis said carefully.

The temperature in the room dropped a good ten degrees. “We cannot model any likely failure mode that reproduces the characteristics,” Van Meurs said frostily.

“What about the echoed signal?”

someone else asked.

“We have several theories that might account for that,” said Dr. Portajee, “including the possibility that something rather like an organic semiconductor is formed in Jupiter’s atmosphere at certain levels.”

Smith pursed his lips. “Speculative,” he pronounced.

“Our computer simulations show—” Portajee began.

“Boundary conditions,” someone further down the table murmured.

“I move we establish a subcommittee to examine the question,” said Wilson.

“You mean a sub-sub-committee,” someone else said. “Logically it should fall under the atmospherics committee.”

“But a separate sub-committee—”

“Boundary conditions. What were the simulation’s boundary conditions?”

“Information theory suggests—”

“Life,” someone said loudly.

Every one stopped and stared at the foot of the table. In horror Suzanne realized the voice had been hers. Instead of muttering it under her breath she had said it out loud.

“Yes, ah, Mzz Quinlan?” Dr. Smith said.

Suzanne Quinlan took a deep breath. “Life. Intelligent life in the clouds of Jupiter.”

There was a long strained silence. Dr. Smith stared down at his notepad. Dr. Lewis licked his lips and concentrated on the ceiling tiles. Van Meurs mumbled something under his breath. Through the silence Suzanne could hear her career splintering and crashing down around her ears. Any instant now one of these men would open his mouth and her Ph.D wouldn’t be worth the paper it was printed on.

“She’s right, you know,” came a quiet voice at her elbow.

“Eh?” Dr. Smith’s eyes jerked down the table to rest on F. Gary Rhine.

“I said she’s right. The best explanation for the data we’ve got is that there is intelligent life on Jupiter that intercepted the probe and is trying to communicate with us.”

“Isn’t that a rather extreme conclusion to draw from the communications glitch?” Lewis asked in a carefully neutral tone.

“It’s not a glitch.”

He ticked off the points on his fingers:

“Something intercepted the probe at the cloud tops and held it there at least until the batteries ran down and it stopped transmitting. Something interfered with the signal at irregular intervals by moving between the transmitter and Galileo. Then, at an eclipse of Europa, we’ve got the signal shot back to us. Deliberately sent back.”

“Analysis indicates the signal is probably random,” said Van Meurs frostily.

Rhine’s smile was almost satanic. “Yeah, but the framing bits aren’t. Whatever it is duplicated our packet structure. Only you didn’t see that because the packets had been stripped off before you were given the data to analyze.”

“But the contents were not duplicated,” Van Meurs said.

“Nope, not the content. That changed almost frame to frame while the probe was sending and they probably didn’t understand it. So they sent values in the observed ranges in there.”

“That takes a fantastic coincidence, that something would be on hand to catch it.”

“Not as much as you think. There’s the probe, floating down like a big fishing lure, it’s going to attract anything curious for hundreds of miles around. Hell, for all we know something snapped it up like a trout on a fly.” He shrugged. “That doesn’t matter. The important thing is, it’s life, it’s intelligent and it wants to say ‘howdy.’ ”

He scanned their faces. “Oh, don’t look so shocked. People have been playing with the idea for decades. Hell, there have even been science fiction stories written around it. Arthur C. Clarke did one years ago.” He grinned ironically. “As well as some more respectable speculation.”

He glared around the room. “The problem with you damn people is you never talk to each other. This whole damn place is organized like a protocol stack with every layer a black box to all the other damn layers.

“You,” he pointed to Van Meurs, “knew all about the flight profile. You,” he pointed to Lewis, “knew about the echo. But you don’t talk except at these damn meetings so you never put it together.” He jerked a nod at Suzanne. “She talks to everyone so she figured it out.”

Smith dug frantically through the printouts.

“But why wait until the eclipse? And why along the path?”

Rhine shrugged. “Ask me again in a couple of years. We’ll know more then.”

“Gentlemen,” Smith announced, “do you realize what this means? It’s the biggest boost for planetary science in the history of space exploration. Why, why, it’ll easily triple our budgets!”

Van Meurs pursed his lips. “If it’s real.”

“For the moment let us proceed as if the phenomenon is real,” Dr. Smith said magisterially. “Why, the possibilities are,” his eyes shone at the thought of all that money, “mind-boggling.”

Suzanne’s head had been swiveling between the participants like a spectator at a tennis match. Rhine touched her shoulder and motioned toward the door. Unnoticed, the pair left the conference room. As they slipped out the door one of the participants was using his putative status on the new project to demand a reserved parking space.

“Shouldn’t we have stayed?” Suzanne asked as the noise faded behind them. “I mean, they might have more questions.”

“They’re beyond fact gathering. Now they’re down to the part that really interests them—how they can make the most out of this. They’ll be arguing about how to spin this until sometime tomorrow morning.”

“But suppose they decide there’s nothing to it after all?”

Rhine grinned a particularly nasty grin. “It doesn’t matter. By this time tomorrow it will be out on the Internet and all over the world.” The grin got even broader and Suzanne developed a sneaking suspicion who the first person to post the news would be. “Hell, woman! How much equipment do you think it takes to get a radio signal to Jupiter? Or hear one coming back? Hams all over the world will set the stuff up in their backyards and every one will be able to hear the results.”

“But what about them?” She tossed her head toward the conference room they had just left.

“They’re irrelevant, but don’t tell them just yet. No reason to hurt their feelings. Meanwhile, I’ve got a friend I want you to meet. A guy by the name of Ed Steveberg in the VLA group. We’ve got us a SETI program to map out. Oh yeah, and there’s another guy, Larry Collins, you should probably talk to pretty soon.” F. Gary Rhine threw a companionable arm around Dr. Suzanne Quinlan’s shoulders. She saw there were tears in his eyes. “God!” he roared down the empty corridor, “I love this job!”
