"The box," he said, "is simply a light microscope fitted with the usual image intensifiers and resolution scanners. We can go up to a thousand diameters with it, projected on the screen here."
Leavitt adjusted dials while Hall and the others stared at the viewer screen.
"Ten power," Leavitt said.
On the screen, Hall saw that the rock was jagged, blackish, dull. Stone pointed out green flecks.
"One hundred power."
The green flecks were larger now, very clear.
"We think that's our organism. We have observed it growing; it turns purple, apparently at the point of mitotic division."
"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.
