Part 24 (2/2)
”But not today.”
”Today.”
”Lie back.”
I fell on the pillows. She tiptoed to the window, a whiteness in the gloom. Drew the curtain. The stars vanished, there was only the slow roar of the Pacific, returning repeatedly with a dreary persistence. I could see practically nothing. The moving air betrayed her steps, the bed sagged.
”Did you ever see a s.h.i.+p of the cla.s.s of the Prometheus?”
”No.”
”It's large. On Earth, it would weigh over three hundred thousand tons.”
”And there were so few of you?”
”Twelve. Tom Arder, Olaf, Arne, Thomas -- the pilots, along with myself. And the seven scientists. If you think that it was empty there, you are wrong. Propulsion takes up nine-tenths of the ma.s.s. Photoaggregates. Storage, supplies, reserve units. The actual living quarters are small. Each of us had a cabin, in addition to the common ones. In the middle part of the body -- the control center and the small landing rockets, and the probes, even smaller, for collecting samples from the corona. . .”
”And you were over Arcturus in one of those?”
”Yes. As was Arder.”
”Why didn't you fly together?”
”In one rocket? It's riskier that way.”
”How?”
”A probe is a cooling system. A sort of flying refrigerator. Just enough room to sit down in. You sit inside a sh.e.l.l of ice. The ice melts from the s.h.i.+eld and refreezes on the pipes. The air compressors can be damaged. All it takes is a moment, because outside the temperature is ten, twelve thousand degrees. When the pipes stop in a two-man rocket, two men die. This way, only one. Do you understand?”
”I understand.”
She put her hand on that unfeeling part of my chest.
”And this. . . happened there?”
”No, Eri; shall I tell you?”
”All right.”
”Only don't think. . . No one knows about this.”
”This?”
The scar stood out under the warmth of her flngers -- as if returning to life.
”Yes.”
”How is that possible? What about Olaf?”
”Not even Olaf. No one knows. I lied to them, Eri. Now I have to tell you, since I've started. Eri. . . it happened in the sixth year. We were on our way back then, but in cloudy regions you can't move quickly. It's a magnificent sight; the faster the s.h.i.+p travels, the stronger the luminescence of the cloud. We had a tail behind us, not like the tail of a comet, more a polar aurora, thin at the sides, deep into the sky, toward Alpha Erida.n.u.s, for thousands and thousands of kilometers. . . Arder and Ennesson were gone by then. Venturi was dead, too. I would wake at six in the morning, when the light was changing from blue to white. I heard Olaf speaking from the controls. He had spotted something interesting. I went down. The radar showed a spot, slightly off our course. Thomas came, and we wondered what the thing could be. It was too big for a meteor, and, anyway, meteors never occur singly. We reduced speed. This woke the rest. When they joined us, I remember, Thomas said it had to be a s.h.i.+p. We often joked like that. In s.p.a.ce there must be s.h.i.+ps from other systems, but two mosquitoes released at opposite ends of the Earth would stand a better chance of meeting. We had reached a gap now in the cloud, and the cold, nebular dust became so dispersed that you could see stars of the sixth magnitude with the naked eye. The spot turned out to be a planetoid. Something like Vesta. A quarter of a billion tons, perhaps more. Extraordinarily regular, almost spherical. Which is quite rare. Two millipa.r.s.ecs off the bow. It was traveling, and we followed. Thurber asked me if we could get closer. I said we could, by a quarter of a millipa.r.s.ec.
”We drew nearer. Through the telescope it looked like a porcupine, a ball bristling with spines. An oddity. Belonged in a museum. Thurber started arguing with Biel about its origin, whether tectonic or not. Thomas b.u.t.ted in, saying that this could be determined. There would be no loss of energy, we hadn't even begun to accelerate. He would fly there, take a few specimens, return. Gimma hesitated. Time presented no problem -- we had some to spare. Finally he agreed. No doubt because I was present. Although I hadn't said a thing. Perhaps because of that. Because our relations.h.i.+p had become. . . but that's another story. We stopped; a maneuver of this kind takes time, and meanwhile the planetoid moved away, but we had it on radar. I was worried, because from the time we started back we had nothing but trouble. Breakdowns, not serious but hard to fix -- and happening without any apparent reason. I'm not superst.i.tious, but I believe in series. Still, I had no argument against his going. It made me look childish, but I checked out Thomas's engine myself and told him to be careful. With the dust.”
”The what?”
”Dust. In the region of a cold cloud, you see, planetoids act like vacuum cleaners. They remove the dust from the s.p.a.ce in their path, and this goes on over a long period of time. The dust settles in layers, which can double the size of the planetoid. A blast from a jet nozzle or even a heavy step is enough to set up a swirling cloud of dust that hangs above the surface. May not sound serious, but you can't see a thing. I told him that. But he knew it as well as I did. Olaf launched him off the s.h.i.+p's side, I went up to navigation and began to guide him down. I saw him approach the planetoid, maneuver, turn his rocket, and descend to the surface, like on a rope. Then, of course, I lost sight of him. But that was five kilometers. . .”
”You picked him up on radar?”
”No, on the optical, that is, by telescope. Infrared. But I could talk to him the whole time. On the radio. Just as I was thinking that I hadn't seen Thomas make such a careful landing in a long time -- we had all become careful on the way back -- I saw a small flash, and a dark stain began to spread across the surface of the planetoid. Gimma, standing next to me, shouted. He thought that Thomas, to brake at the last moment, had hit the flame. That's an expression we use. You give one short blast of the engine, naturally not in such circ.u.mstances. And I knew that Thomas would never have done that. It had to be lightning.”
”Lightning? There?”
”Yes. You see, any body moving at high speed through a cloud builds up charge, static electricity, from friction. There was a difference in potential between the Prometheus and the planetoid. It could have been billions of volts. More, even. When Thomas landed, a spark leapt. That was the flash, and because of the sudden heat the dust rose, and in a minute the entire surface was covered by a cloud. We couldn't hear him -- his radio just crackled. I was furious, mainly at myself, for having underestimated. The rocket had special lightning conductors, p.r.o.nged, and the charge should have pa.s.sed quietly into St. Elmo's fire. But it didn't. It was exceptionally powerful. Gimma asked me when I thought the dust would settle. Thurber didn't ask; it was clear that it would take days.”
”Days?”
”Yes. Because the gravity was extremely low. If you dropped a stone, it would fall for several hours before hitting the ground. Think how much longer it would take dust to settle after being thrown up a hundred meters. I told Gimma to go about his business, because we had to wait.”
”And nothing could be done?”
”No. If I could be sure that Thomas was still inside his rocket, I would have taken a chance -- turned the Prometheus around, got close to the planetoid, and blasted the dust off to all four corners of the galaxy -- but I could not be sure. And finding him? The surface of the planetoid had an area equal to, I don't know, that of Corsica. Besides, in the dust cloud you could walk right by him at arm's length and not see him. There was only one solution. He had it at his fingertips. He could have taken off and returned.”
”He didn't do that?”
”No.”
”Do you know why?”
”I can guess. He would have had to take off blind. I could see that the cloud reached, well, not quite a kilometer above the surface, but he didn't know that. He was afraid of hitting an overhang or a rock. He might have landed on the bottom of some deep gorge. So we hung there a day, two days; he had enough oxygen and provisions for six. Emergency rations. No I one was in a position to do anything. We paced and thought up ways of getting Thomas out of this mess. Emitters. Different wavelengths. We even threw down flares. They didn't work, that cloud was as dark as a tomb. A third day -- a third night. Our measurements showed that the cloud was settling, but I wasn't sure it would finish coming down in the seventy hours left to Thomas. He could last without food far longer, but not without oxygen. Then I got an idea. I reasoned this way: Thomas's rocket was made primarily of steel. Provided there were no iron ores on that d.a.m.ned planetoid, it might be possible to locate him with a ferromagnetic indicator -- a device for finding iron objects. We had a highly sensitive one. It could pick up a nail at a distance of three-quarters of a kilometer. A rocket at several kilometers. Olaf and I went over the apparatus. Then I told Gimma and took off.”
”Alone.”
”Yes.”
”Why?”
”Because without Thomas there were only the two of us, and the Prometheus had to have a pilot.”
