thinking out loud. “Powerful magnetic fields. Must have been hundreds of thousands of Gauss?”
“That wouldn’t be enough. You’d need millions for that,” the astrogator answered in a gruff voice. Only now did he become aware of Rohan’s presence.
“Come in and close the door behind you!”
“Millions? Wouldn’t our instruments here on board detect such a field?”
“Only under certain conditions,” replied Horpach. “If it were concentrated in a small area, if it were the size of this glove here, and if in addition it were screened off from the outside…”
“In short, if Kertelen had stuck his head between the poles of a gigantic electromagnet — ”
“Even that wouldn’t be sufficient. The field would have to oscillate in a certain frequency.”
“But there was nothing but rubble up there. There were no machines and no magnets, nothing but eroded ravines, gravel and sand.”
“And caves,” Horpach added meaningfully.
“And caves. Do you believe somebody pulled him into one of those caves and that there was a magnet in it? No, that’s — ”
“How else can you account for it?” asked the commander, as if he had grown tired of this discussion.
The physician remained silent.
At 3:40 A.M. the shrill ringing of the alarm signals sounded throughout the
Rohan checked the dials of the field control instruments. He had programed the computers himself and knew they would not react to rain or sandstorms.
Something — it was too dark to make out what it was — came rushing from the direction of the desert and scattered in a rain of fire. The discharges occurred at the surface of the energy dome. The mysterious missiles bounced off the shield and flew back, rapidly fading flames along a parabolic curve. Still other flames slid down the curvature of the vaulted field. The ridges of the dunes became momentarily visible, then sank back again into the darkness.
The hands on the dials flicked sluggishly. The system of the Diracs needed only a relatively small effort to ward off this mysterious bombardment. Rohan heard the approaching steps of the commander as he looked across to the spectrometer installation.
“Nickel, iron, manganese, beryllium, titanium,” the astrogator read the results off the brightly illuminated scale. He stood next to Rohan. “What I wouldn’t give to be able to see with my own eyes what’s going on there.”
“It’s raining metallic particles,” said Rohan slowly. “They must be quite small to judge by their discharges.”
“I’d like to get a close look at them,” said the astrogator. “How about it? Shall we risk it?”
“You mean switch off the energy field?”
“Yes. For a fraction of a second. We’ll catch a few particles inside the protected zone, the rest will be repelled when we switch our energy field back on.”
Rohan did not answer for a long time.
“Well, it’s conceivable…” he finally said.
But before the commander had time to step over to the instrument panel, the flickering flames died down just as rapidly as they had flared up. Stark darkness reigned again, the kind that is known only on moonless planets that circle far from the star clusters of the galaxy.
“No luck this time,” muttered Horpach. His hand rested on the main switch. He remained standing for another minute, then nodded briefly in Rohan’s direction and left the room. The all-clear signal sounded throughout all levels of the spaceship.
Rohan sighed, glanced once again at the videoscreens: there was nothing on the image but pitch black darkness. Then he went back to bed.
THE CLOUD
They were getting used to the planet, its never-changing desert face, the slight shadows cast by its unnaturally light clouds as they drifted apart. Even by daylight one could see them through the light of the bright stars. They came to accept the ever-present sand that crunched under wheel and foot. They even grew accustomed to the dull red sun, whose rays were incomparably softer than those of its terrestrial counterpart. Instead of warmth, one felt its silent presence whenever the back was turned.
Every morning the work troops set out, each one in a different direction. The energo-robots disappeared among the dunes, rocking like giant boats. Once the dust cloud settled those who remained at the
Without the novelty which had originally inspired them when they were working in the metallic debris of the “city,” their energy soon dissipated. Hardly a week had gone by when even the
Rohan would never have believed it possible, but in less than a week he was behaving no differently than the rest of the crew. Only on rare occasions, when he was completely alone would he begin to wonder what he was doing there. All this work, their antlike activity, the complicated details of their research: the transilluminations, the search for specimens, the rock drillings (which were made even more difficult by the third step routine), the opening and closing of the energy fields, the laser weapons with their exactly prescribed firing range, the unending visual control, the constant calculations — all this, he realized, was nothing but self-deceit. Basically, they were doing nothing more than wait for some new event, another catastrophe. They were simply pretending that they did not know the real reason for all this busy-work.
At first the men would crowd around the ship’s infirmary every morning to wait for news about Kertelen. He seemed to them not so much the victim of a mysterious attack as some creature who no longer resembled a human being, a monster who had nothing in common with them. It was as if they believed they were in some fantastic fairytale, in which an unknown force from a hostile planet had changed one of them into a monster. In reality, of course, the man was nothing but a cripple. Moreover, it soon became apparent that his brain was simply empty, like that of a newborn baby. His mind was able to absorb all the knowledge the doctors would teach it. Gradually, like an infant, he began to talk. Those who passed the hospital no longer heard the strange whining sounds, unlike any produced by human voices, or that senseless baby’s crying that had been so terrible because it came from the mouth of a grown man. One week later, Kertelen formed his first syllables and began to recognize the physicians, although he could not yet pronounce their names.
By the second week, the men had lost interest in him, especially after the doctors announced that he would
