New Frontiers (6 page)

Deep in the starship's bowels the fusion generator forced the hydrogen ions to fuse together into helium ions, giving up energy in the process to run the ship. Like the Sun and the stars themselves, the starship lived on hydrogen fusion.

Ignatiev slid the door of his quarters shut. The suite of rooms allotted to him was small, but far more luxurious than any home he had lived in back on Earth. The psychotechnicians among the mission's planners, worried about the crew's morale during the decades-long flight, had insisted on every creature comfort they could think of: everything from body-temperature waterbeds that adjusted to one's weight and size to digitally controlled décor that could change its color scheme at the call of one's voice; from an automated kitchen that could prepare a world-spanning variety of cuisines to virtual reality entertainment systems.

Ignatiev ignored all the splendor; or rather, he took it for granted. Creature comforts were fine, but he had spent the first months of the mission converting his beautifully wrought sitting room into an astrophysics laboratory. The sleek Scandinavian desk of teak inlaid with meteoric silver now held a conglomeration of computers and sensor readouts. The fake fireplace was hidden behind a junk pile of discarded spectrometers, magnetometers, and other gadgetry that Ignatiev had used and abandoned. He could see a faint ring of dust on the floor around the mess; he had given the cleaning robots strict orders not to touch it.

Above the obstructed fireplace was a framed digital screen programmed to show high-definition images of the world's great artworks—when it wasn't being used as a three-dimensional entertainment screen. Ignatiev had connected it to the ship's main optical telescope, so that it showed the stars spangled against the blackness of space. Usually the telescope was pointed forward, with the tiny red dot of Gliese 581 centered in its field of view. Now and then, at the command of the ship's AI system, it looked back toward the diminishing yellow speck of the Sun.

Being an astrophysicist, Ignatiev had started the flight by spending most of his waking hours examining this interstellar Siberia in which he was exiled. It was an excuse to stay away from the chattering young monkeys of the crew. He had studied the planet-sized chunks of ice and rock in the Oort cloud that surrounded the outermost reaches of the solar system. Once the ship was past that region, he turned his interest back to the enigmatic, frustrating pulsars. Each one throbbed at a precise frequency, more accurate than an atomic clock. Why? What determined their frequency? Why did some supernova explosions produce pulsars while others didn't?

Ignatiev batted his head against those questions in vain. More and more, as the months of the mission stretched into years, he spent his days playing chess against the AI system. And losing consistently.

“Alexander Alexandrovich.”

He looked up from the chessboard he had set up on his desktop screen, turned in his chair, and directed his gaze across the room to the display screen above the fireplace. The lovely, smiling face of the artificial intelligence system's avatar filled the screen.

The psychotechnicians among the mission planners had decided that the human crew would work more effectively with the AI program if it showed a human face. For each human crew member, the face was slightly different: the psychotechs had tried to create a personal relationship for each of the crew. The deceit annoyed Ignatiev. The program treated him like a child. Worse, the face it displayed for him reminded him too much of his late wife.

“I'm busy,” he growled.

Unperturbed, the avatar's smiling face said, “Yesterday you requested use of the main communications antenna.”

“I want to use it as a radio telescope, to map out the interstellar hydrogen we're moving through.”

“The twenty-one-centimeter radiation,” said the avatar knowingly.

“Yes.”

“You are no longer studying the pulsars?”

He bit back an angry reply. “I have given up on the pulsars,” he admitted. “The interstellar medium interests me more. I have decided to map the hydrogen in detail.”

Besides, he admitted to himself, that will be a lot easier than the pulsars.

The AI avatar said calmly, “Mission protocol requires the main antenna be available to receive communications from mission control.”

“The secondary antenna can do that,” he said. Before the AI system could reply, he added, “Besides, any communications from Earth will be six years old. We're not going to get any urgent messages that must be acted upon immediately.”

“Still,” said the avatar, “mission protocol cannot be dismissed lightly.”

“It won't hurt anything to let me use the main antenna for a few hours each day,” he insisted.

The avatar remained silent for several seconds: an enormous span of time for the computer program.

At last, the avatar conceded, “Perhaps so. You may use the main antenna, provisionally.”

“I am eternally grateful,” Ignatiev said. His sarcasm was wasted on the AI system.

As the weeks lengthened into months he found himself increasingly fascinated by the thin interstellar hydrogen gas and discovered, to only his mild surprise, that it was not evenly distributed in space.

Of course, astrophysicists had known for centuries that there are regions in space where the interstellar gas clumped so thickly and was so highly ionized that it glowed. Gaseous emission nebulae were common throughout the galaxy, although Ignatiev mentally corrected the misnomer: those nebulae actually consisted not of gas, but of plasma—gas that is highly ionized.

But here in the placid emptiness on the way to Gliese 581 Ignatiev found himself slowly becoming engrossed with the way that the thin, bland neutral interstellar gas was not evenly distributed. Not at all. The hydrogen was thicker in some regions than in others.

This was hardly a new discovery, but from the viewpoint of the starship, inside the billowing interstellar clouds, the fine structure of the hydrogen became almost a thing of beauty in Ignatiev's ice-blue eyes. The interstellar gas didn't merely hang there passively between the stars, it flowed: slowly, almost imperceptibly, but it drifted on currents shaped by the gravitational pull of the stars.

“That old writer was correct,” he muttered to himself as he studied the stream of interstellar hydrogen that the ship was cutting through. “There are currents in space.”

He tried to think of the writer's name, but couldn't come up with it. A Russian name, he recalled. But nothing more specific.

The more he studied the interstellar gas, the more captivated he became. He went days without playing a single game of chess. Weeks. The interstellar hydrogen gas wasn't static, not at all. It was like a beautiful intricate lacework that flowed, fluttered, shifted in a stately silent pavane among the stars.

The clouds of hydrogen were like a tide of bubbling champagne, he saw, frothing slowly in rhythm to the heartbeats of the stars.

The astronomers back on Earth had no inkling of this. They looked at the general features of the interstellar gas, scanning at ranges of kiloparsecs and more; they were interested in mapping the great sweep of the galaxy's spiral arms. But here, traveling inside the wafting, drifting clouds, Ignatiev measured the detailed configuration of the interstellar hydrogen and found it beautiful.

He slumped back in his form-fitting desk chair, stunned at the splendor of it all. He thought of the magnificent panoramas he had seen of the cosmic span of the galaxies: loops and whorls of bright shining galaxies, each one containing billions of stars, extending for megaparsecs, out to infinity, long strings of glowing lights surrounding vast bubbles of emptiness. The interstellar gas showed the same delicate complexity, in miniature: loops and whorls, streams and bubbles. It was truly, cosmically beautiful.

“Fractal,” he muttered to himself. “The universe is one enormous fractal pattern.”

Then the artificial intelligence program intruded on his privacy. “Alexander Alexandrovich, the weekly staff meeting begins in ten minutes.”

WEEKLY STAFF MEETING,
Ignatiev grumbled inwardly as he hauled himself up from his desk chair. More like the weekly group therapy session for a gaggle of self-important juvenile delinquents.

He made his way grudgingly through the ship's central passageway to the conference room, located next to the command center. Several other crew members were also heading along the gleaming brushed chrome walls and colorful carpeting of the passageway. They gave Ignatiev cheery, smiling greetings; he nodded or grunted at them.

As chief executive of the crew, Ignatiev took the chair at the head of the polished conference table. The others sauntered in leisurely. Nikki and Gregorian came in almost last and took seats at the end of the table, next to each other, close enough to hold hands.

These meetings were a pure waste of time, Ignatiev thought. Their ostensible purpose was to report on the ship's performance, which any idiot could determine by casting half an eye at the digital readouts available on any display screen in the ship. The screens gave up-to-the-nanosecond details of every component of the ship's equipment.

But no, mission protocol required that all twelve crew members must meet face-to-face once each week. Good psychology, the mission planners believed. An opportunity for human interchange, personal communications. A chance for whining and displays of overblown egos, Ignatiev thought. A chance for these sixty-year-old children to complain about one another.

Of the twelve of them, only Ignatiev and Nikki were physicists. Four of the others were engineers of various stripes, three were biologists, two psychotechnicians, and one stocky, sour-faced woman a medical doctor.

So he was quite surprised when the redheaded young electrical engineer in charge of the ship's power system started the meeting by reporting:

“I don't know if any of you have noticed it yet, but the ship's reduced our internal electrical power consumption by ten percent.”

Mild perplexity.

“Ten percent?”

“Why?”

“I haven't noticed any reduction.”

The redhead waved his hands vaguely as he replied, “It's mostly in peripheral areas. Your microwave ovens, for example. They've been powered down ten percent. Lights in unoccupied areas. Things like that.”

Curious, Ignatiev asked, “Why the reduction?”

His squarish face frowning slightly, the engineer replied, “From what Alice tells me, the density of the gas being scooped in for the generator has decreased slightly. Alice says it's only a temporary condition. Nothing to worry about.”

Alice was the nickname these youngsters had given to the artificial intelligence program that actually ran the ship. Artificial Intelligence. AI. Alice Intellectual. Some even called the AI system Alice Imperatress. Ignatiev thought it childish nonsense.

“How long will this go on?” asked one of the biologists. “I'm incubating a batch of genetically-engineered algae for an experiment.”

“It shouldn't be a problem,” the engineer said. Ignatiev thought he looked just the tiniest bit worried.

Surprisingly, Gregorian piped up. “A few of the uncrewed probes that went ahead of us also encountered power anomalies. They were temporary. No big problem.”

Ignatiev nodded but made a mental note to check on the situation. Six light-years out from Earth, he thought, meant that every problem was a big one.

One of the psychotechs cleared her throat for attention, then announced, “Several of the crew members have failed to fill out their monthly performance evaluations. I know that some of you regard these evaluations as if they were school exams, but mission protocol—”

Ignatiev tuned her out, knowing that they would bicker over this drivel for half an hour, at least. He was too optimistic. The discussion became quite heated and lasted more than an hour.

ONCE THE MEETING
finally ended Ignatiev hurried back to his quarters and immediately looked up the mission logs of the six automated probes that had been sent to Gliese 581.

Gregorian was right, he saw. Half of the six probes had reported drops in their power systems, a partial failure of their fusion generators. Three of them. The malfunctions were only temporary, but they occurred at virtually the same point in the long voyage to Gliese 581.

The earliest of the probes had shut down altogether, its systems going into hibernation for more than four months. The mission controllers back on Earth had written the mission off as a failure when they could not communicate with the probe. Then, just as abruptly as the ship had shut down, it sprang to life again.

Puzzling.

“Alexander Alexandrovich,” called the AI system's avatar. “Do you need more information on the probe missions?”

He looked up from his desk to see the lovely female face of the AI program's avatar displayed on the screen above his fireplace. A resentful anger simmered inside him. The psychotechs suppose that the face they've given the AI system makes it easier for me to interact with it, he thought. Idiots. Fools.

“I need the mission controllers' analyses of each of the probe missions,” he said, struggling to keep his voice cool, keep the anger from showing.

“May I ask why?” The avatar smiled at him. Sonya, he thought. Sonya.

“I want to correlate their power reductions with the detailed map I'm making of the interstellar gas.”

“Interesting,” said the avatar.

“I'm pleased you think so,” Ignatiev replied, through gritted teeth.

The avatar's image disappeared, replaced by data scrolling slowly along the screen. Ignatiev settled deeper into the form-adjusting desk chair and began to study the reports.

His door buzzer grated in his ears. Annoyed, Ignatiev told his computer to show who was at the door.

Gregorian was standing out in the passageway, tall, lanky, egocentric Gregorian. What in hell could he want? Ignatiev asked himself.
