“Spectrum shift?”
“Of some kind.”
“One thousand power,” Leavitt said.
The screen was filled with a single green spot, nestled down in the jagged hollows of the rock. Hall noticed the surface of the green, which was smooth and glistening, almost oily.
“You think that’s a single bacterial colony?”
“We can’t be sure it’s a colony in the conventional sense,” Stone said. “Until we heard Burton’s experiments, we didn’t think it was a colony at all. We thought it might be a single organism. But obviously the single units have to be a micron or less in size; this is much too big. Therefore it is probably a larger structure– perhaps a colony, perhaps something else.”
As they watched, the spot turned purple, and green again. “It’s dividing now,” Stone said. “Excellent.”
Leavitt switched on the cameras.
“Now watch closely.”
The spot turned purple and held the color. It seemed to expand slightly, and for a moment, the surface broke into fragments, hexagonal in shape, like a tile floor.
“Did you see that?”
“It seemed to break up.”
“Into six-sided figures.”
“I wonder,” Stone said, “whether those figures represent single units.”
“Or whether they are regular geometric shapes all the time, or just during division?”
“We’ll know more,” Stone said, “after the EM.” He turned to Burton. “Have you finished your autopsies?”
“Yes.”
“Can you work the spectrometer?”
“I think so.”
“Then do that. It’s computerized, anyway. We’ll want an analysis of samples of both the rock and the green organism.”
“You’ll get me a piece?”
“Yes.” Stone said to Leavitt: “Can you handle the AA analyzer? ”
“Yes.”
“Same tests on that.”
“And a fractionation?”
“I think so,” Stone said. “But you’ll have to do that by hand.”
Leavitt nodded; Stone turned back to the isolation chamber and removed a glass dish from the light microscope. He set it to one side, beneath a small device that looked like a miniature scaffolding. This was the microsurgical unit.
Microsurgery was a relatively new skill in biology– the ability to perform delicate operations on a single cell. Using microsurgical techniques, it was possible to remove the nucleus from a cell, or part of the cytoplasm, as neatly and cleanly as a surgeon performed an amputation.
The device was constructed to scale down human hand movements into fine, precise miniature motions. A series of gears and servomechanisms carried out the reduction; the movement of a thumb was translated into a shift of a knife blade millionths of an inch.
Using a high magnification viewer, Stone began to chip away delicately at the black rock, until he had two tiny fragments. He set them aside in separate glass dishes and proceeded to scrape away two small fragments from the green area.
Immediately, the green turned purple, and expanded.
“It doesn’t like you,” Leavitt said, and laughed.
Stone frowned. “Interesting. Do you suppose that’s a nonspecific growth response, or a trophic response to injury and irradiation? ”
“I think,” Leavitt said, “that it doesn’t like to be poked at.”
“We must investigate further,” Stone said.
19. Crash
FOR ARTHUR MANCHEK, THERE WAS A CERTAIN kind of horror in the telephone conversation. He received it at home, having just finished dinner and sat down in the living room to read the newspapers. He hadn’t seen a newspaper in the last two days, he had been so busy with the Piedmont business.
When the phone rang, he assumed that it must be for his wife, but a moment later she came in and said, “It’s for you. The base.”
He had an uneasy feeling as he picked up the receiver. “Major Manchek speaking.”
“Major, this is Colonel Burns at Unit Eight.” Unit Eight was the processing and clearing unit of the base. Personnel checked in and out through Unit Eight, and calls were transmitted through it.
“Yes, Colonel?”
“Sir, we have you down for notification of certain contingencies. ” His voice was guarded; he was choosing his words carefully on the open line. “I’m informing you now of an RTM crash forty-two minutes ago in Big Head, Utah.”
Manchek frowned. Why was he being informed of a routine training-mission crash? It was hardly his province.
“What was it?”
“Phantom, Sir. En route San Francisco to Topeka.”
“I see,” Manchek said, though he did not see at all.
“Sir, Goddard wanted you to be informed in this instance so that you could join the post team.”
“Goddard? Why Goddard?” For a moment, as he sat there in the living room, staring at the newspaper headline absently– NEW BERLIN CRISIS FFARED– he thought that the colonel meant Lewis Goddard, chief of the codes section of Vandenberg. Then he realized he meant Goddard Spaceflight Center, outside Washington. Among other things, Goddard acted as collating center for certain special projects that fell between the province of Houston and the governmental agencies in Washington.
“Sir,” Colonel Burns said, “the Phantom drifted off its flight plan forty minutes out of San Francisco and passed through Area WF.”
Manchek felt himself slowing down. A kind of sleepiness came over him. “Area WF?”
“That is correct, Sir.
“When?”
“Twenty minutes before the crash.”
“At what altitude?”
“Twenty-three thousand feet, Sir.”
“When does the post team leave?”
“Half an hour, Sir, from the base.”
“All right,” Manchek said. “I’ll be there.”
He hung up and stared at the phone lazily. He felt tired; he wished he could go to bed. Area WF was the designation for the cordoned-off radius around Piedmont, Arizona.
They should have dropped the bomb, he thought. They should have dropped it two days ago.
At the time of the decision to delay Directive 7-12, Manchek had been uneasy. But officially he could not express an opinion, and he had waited in vain for the Wildfire team, now located in the underground laboratory, to complain to Washington. He knew Wildfire had been notified; he had seen the cable that went to all security units; it was quite explicit.
Yet for some reason Wildfire had not complained. Indeed, they had paid no attention to it whatever.
Very odd.
And now there was a crash. He lit his pipe and sucked on it, considering the possibilities. Overwhelming was the likelihood that some green trainee had daydreamed, gone off his flight plan, panicked, and lost control of the plane. It had happened before, hundreds of times. The post team, a group of specialists who went out to the site of the wreckage to investigate all crashes, usually returned a verdict of “Agnogenic Systems Failure.” It was military doubletalk for crash of unknown cause; it did not distinguish between mechanical failure and pilot failure, but it was known that most systems failures were pilot failures. A man could not afford to daydream when he was running a complex machine at two thousand miles an hour. The proof lay in the statistics: though only 9 per cent of flights occurred after the pilot had taken a leave or weekend pass, these flights accounted for 27 per cent of casualties.
Manchek’s pipe went out. He stood, dropping the newspaper, and went into the kitchen to tell his wife he was leaving.
***
“This is movie country,” somebody said, looking at the sandstone cliffs, the brilliant reddish hues, against the deepening blue of the sky. And it was true, many movies had been filmed in this area of Utah. But Manchek could not think of movies now. As he sat in the back of the limousine moving away from the Utah airport, he considered what he had been told.
During the flight from Vandenberg to southern Utah, the post team had heard transcripts of the flight transmission between the Phantom and Topeka Central. For the most part it was dull, except for the final moments before the pilot crashed.
The pilot had said: “Something is wrong.”
And then, a moment later, “My rubber air hose is dissolving. It must be the vibration. It’s just disintegrating to dust.”
Perhaps ten seconds after that, a weak, fading voice said, “Everything made of rubber in the cockpit is dissolving.”
There were no further transmissions.
Manchek kept hearing that brief communication, in his mind, over and over. Each time, it sounded more bizarre and terrifying.
He looked out the window at the cliffs. The sun was setting now, and only the tops of the cliffs were lighted by fading reddish sunlight; the valleys lay in darkness. He looked ahead at the other limousine, raising a small dust cloud as it carried the rest of the team to the crash site.
“I used to love westerns,” somebody said. “They were all shot out here. Beautiful country.”
Manchek frowned. It was astonishing to him how people could spend so much time on irrelevancies. Or perhaps it was just denial, the unwillingness to face reality.
The reality was cold enough: the Phantom had strayed into Area WF, going quite deep for a matter of six minutes before the pilot realized the error and pulled north again. However, once in WF, the plane had begun to lose stability. And it had finally crashed.
He said, “Has Wildfire been informed?”
A member of the group, a psychiatrist with a crew cut– all post teams had at least one psychiatrist– said, “You mean the germ people?”
“Yes.”
“They’ve been told,” somebody else said. “It went out on the scrambler an hour ago.”
Then, thought Manchek, there would certainly be a reaction from Wildfire. They could not afford to ignore this.
Unless they weren’t reading their cables. It had never occurred to him before, but perhaps it was possible– they weren’t reading the cables. They were so absorbed in their work, they just weren’t bothering.
“There’s the wreck,” somebody said. “Up ahead.”
***
Each time Manchek saw a wreck, he was astonished. Somehow, one never got used to the idea of the sprawl, the mess, the destructive force of a large metal object striking the earth at thousands of miles an hour. He always expected a neat, tight little clump of metal, but it was never that way.
The wreckage of the Phantom was scattered over two square miles of desert. Standing next to the charred remnants of the left wing, he could barely see the others, on the horizon, near the right wing. Everywhere he looked, there were bits of twisted metal, blackened, paint peeling. He saw one with a small portion of a sign still intact, the stenciled letters clear: DO NOT. The rest was gone.
It was impossible to make anything of the remnants. The fuselage, the cockpit, the canopy were all shattered into a million fragments, and the fires had disfigured everything.
As the sun faded, he found himself standing near the remains of the tail section, where the metal still radiated heat from the smoldering fire. Half-buried in the sand he saw a bit of bone; he picked it up and realized with horror that it was human. Long, and broken, and charred at one end, it had obviously come from an arm or a leg. But it was oddly clean– there was no flesh remaining, only smooth bone.
Darkness descended, and the post team took out their flashlights, the half-dozen men moving among, smoking metal, flashing their yellow beams of light about.
It was late in the evening when a biochemist whose name he did not know came up to talk with him.
“You know,” the biochemist said, “it’s funny. That transcript about the rubber in the cockpit dissolving.”
“How do you mean?”
“Well, no rubber was used in this airplane. It was all a synthetic plastic compound. Newly developed by Ancro; they’re quite proud of it. It’s a polymer that has some of the same characteristics as human tissue. Very flexible, lots of applications. ”
Manchek said, “Do you think vibrations could have caused the disintegration.”
“No,” the man said. “There are thousands of Phantoms flying around the world. They all have this plastic. None of them has ever had this trouble.”
“Meaning?”
“Meaning that I don’t know what the hell is going on,” the biochemist said.
20. Routine
SLOWLY, THE WILDFIRE INSTALLATION SETTLED into a routine, a rhythm of work in the underground chambers of a laboratory where there was no night or day, morning or afternoon. The men slept when they were tired, awoke when they were refreshed, and carried on their work in a number of different areas.
Most of this work was to lead nowhere. They knew that, and accepted it in advance. As Stone was fond of saying, scientific research was much like prospecting: you went out and you hunted, armed with your maps and your instruments, but in the end your preparations did not matter, or even your intuition. You needed your luck, and whatever benefits accrued to the diligent, through sheer, grinding hard work.
Burton stood in the room that housed the spectrometer along with several other pieces of equipment for radioactivity assays, ratio-density photometry, thermocoupling analysis, and preparation for X-ray crystallography.
The spectrometer employed in Level V was the standard Whittington model K-5. Essentially it consisted of a vaporizer, a prism, and a recording screen. The material to be tested was set in the vaporizer and burned. The light from its burning then passed through the prism, where it was broken down to a spectrum that was projected onto a recording screen. Since different elements gave off different wavelengths of light as they burned, it was possible to analyze the chemical makeup of a substance by analyzing the spectrum of light produced.
In theory it was simple, but in practice the reading of spectrometrograms was complex and difficult. No one in this Wildfire laboratory was trained to do it well. Thus results were fed directly into a computer, which performed the analysis. Because of the sensitivity of the computer, rough percentage compositions could also be determined.
Burton placed the first chip, from the black rock, onto the vaporizer and pressed the button. There was a single bright burst of intensely hot light; he turned away, avoiding the brightness, and then put the second chip onto the lamp. Already, he knew, the computer was analyzing the light from the first chip.
He repeated the process with the green fleck, and then checked the time. The computer was now scanning the self-developing photographic plates, which were ready for viewing in seconds. But the scan itself would take two hours– die electric eye was very slow.
Once the scan was completed, the computer would analyze results and print the data within five seconds.
The wall clock told him it was now 1500 hours– three in the afternoon. He suddenly realized he was tired. He punched in instructions to the computer to wake him when analysis was finished. Then he went off to bed.
***
In another room, Leavitt was carefully feeding similar chips into a different machine, an amino-acid analyzer. As he did so, he smiled slightly to himself, for he could remember how it had been in the old days, before AA analysis was automatic.
In the early fifties, the analysis of amino acids in a protein might take weeks, or even months. Sometimes it took years. Now it took hours– or at the very most, a day– and it was fully automatic.
Amino acids were the building blocks of proteins. There were twenty-four known amino acids, each composed of a half-dozen molecules of carbon, hydrogen, oxygen, and nitrogen. Proteins were made by stringing these amino acids together in a line, like a freight train. The order of stringing determined the nature of the protein– whether it was insulin, hemoglobin, or growth hormone. All proteins were composed of the same freight cars, the same units. Some proteins had more of one kind of car than another, or in a different order. But that was the only difference. The same amino acids, the same freight cars, existed in human proteins and flea proteins.
That fact had taken approximately twenty years to discover.
But what controlled the order of amino acids in the protein? The answer turned out to be DNA, the genetic-coding substance, which acted like a switching manager in a freightyard.
That particular fact had taken another twenty years to discover.
But then once the amino acids were strung together, they began to twist and coil upon themselves; the analogy became closer to a snake than a train. The manner of coiling was determined by the order of acids, and was quite specific: a protein had to be coiled in a certain way, and no other, or it failed to function.
Another ten years.
Rather odd, Leavitt thought. Hundreds of laboratories, thousands of workers throughout the world, all bent on discovering such essentially simple facts. It had all taken years and years, decades of patient effort.
And now there was this machine. The machine would not, of course, give the precise order of amino acids. But it would give a rough percentage composition: so much valine, so much arginine, so much cystine and proline and leucine. And that, in turn, would give a great deal of information.
Yet it was a shot in the dark, this machine. Because they had no reason to believe that either the rock or the green organism was composed even partially of proteins. True, every living thing on earth had at least some proteins– but that didn’t mean life elsewhere had to have it.
For a moment, he tried to imagine life without proteins. It was almost impossible: on earth, proteins were part of the cell wall, and comprised all the enzymes known to man. And life without enzymes? Was that possible?
He recalled the remark of George Thompson, the British biochemist, who had called enzymes “the matchmakers of life.” It was true; enzymes acted as catalysts for all chemical reactions, by providing a surface for two molecules to come together and react upon. There were hundreds of thousands, perhaps millions, of enzymes, each existing solely to aid a single chemical reaction. Without enzymes, there could be no chemical reactions.
Without chemical reactions, there could be no life.
Or could there?
It was a long-standing problem. Early in planning Wildfire, the question had been posed: How do you study a form of life totally unlike any you know? How would you even know it was alive?
This was not an academic matter. Biology, as George Wald had said, was a unique science because it could not define its subject matter. Nobody had a definition for life. Nobody knew what it was, really. The old definitions– an organism that showed ingestion, excretion, metabolism, reproduction, and so on– were worthless. One could always find exceptions.
