Rohan wanted to ask another question, but he could not muster up sufficient courage. The words would not pass his lips. Horpach looked at him, as if he were waiting for something. But Rohan did not know what to say. Could the commander possibly assume that he, Rohan, would come up with something better, more perfect than the scientists, than the cyberneticists and the strategists with their electronic computers to help them? That was sheer nonsense. Yet the commander kept patiently staring at him. Neither of them spoke. At regular intervals came the drip-drip-drip of the faucets, uncommonly loud in this complete stillness. And out of this silence that hovered between the two men something rose, brushing against Rohan’s cheeks with its icy breath. And now his whole face, from his neck to his jaws, cramped together, shrank, became too narrow, as he gazed into Horpach’s watery, ancient eyes. He saw nothing but these eyes and he knew what he had to do.
Slowly he nodded his head, as if he had said yes. Do you understand? the astrogator asked with his eyes. I understand, replied Rohan with a silent glance. But the clearer things became to Rohan, the more he felt that no one had the right to request something like this from him, no one, not even he himself. He maintained his silence, he did not speak, but now he pretended not to know anything, not to have even the faintest idea. He clung to the naive hope that he would be able to deny what had passed back and forth in their glances, for it had never been spoken out loud. He might feign lack of comprehension, for he knew, he could feel it, Horpach would never be the first to speak. But the old man saw through him, he was aware of everything. Thus they sat across from each other without moving. Horpach’s glance softened. It held now neither expectation nor coercive urgency, only compassion, as if he wanted to say: All right, I understand. It’s just as well.
The commander lowered his head. One more second, and the unspoken words, the agreement between them that only silent glances had implied, would vanish. Both could pretend that nothing had ever happened. But the lowered head tipped the balance. Rohan heard himself say: “I’ll go.”
Horpach sighed deeply, but Rohan did not notice. He was aghast at his own words.
“No,” said Horpach, “I won’t let you go this way.” Rohan was silent. “I couldn’t tell you,” the astrogator began. “I could not even look for any volunteers. I have no right to do such a thing. But now you know for yourself that we can’t simply take off from this planet. Only a single person, all alone, can walk into that area and hope to come out again. Without protective helmet, machines or weapons.”
Rohan heard the commander’s voice as from a great distance.
“I’m going to explain my plan now. You can think about it. You may reject it — the whole thing is still simply between the two of us. This is the way I envision it: an oxygen container made of silicone. No metal. I’ll send two unmanned cross-country vehicles. They will act as a decoy for the black insects and will be destroyed by the cloud. At the same time a third vehicle will start out with one man. This is the most dangerous part, because he must keep as close as possible so as not to waste any time for the march through the desert. The oxygen supply will hold out eighteen hours. Here are some photograms of the entire ravine and its surroundings. I think it would be advisable to follow a different route than on the previous expeditions. Drive as close as possible to the northern rim of the high plateau and then descend on foot over the rocks into the upper part of the ravine. If they’re any place, that’s where they would be. They could have made it there. The terrain is difficult, full of caves and crevices. In case you should find all of them or even just one…”
“That’s it. How shall I transport them?” asked Rohan and he experienced a fleeting smugness. This is where the plan would fall apart. How ready Horpach was to sacrifice him…
“You’ll carry along some suitable narcotic. Something to stun them. Of course, you’ll use it only if they refuse to walk. Fortunately, they all can walk in that condition.
Fortunately, thought Rohan. He clenched his fists underneath the table so that Horpach would not notice it. He was not afraid, not yet. Everything seemed too unreal.
“Should the cloud become interested in you, then you must lie on the ground and remain rigid. I have thought of some medication for such an eventuality, but it would take too long to take effect. That leaves only the protective head gear, the current simulator that Sax mentioned.”
“Have they built one already?” asked Rohan. Horpach understood what his question implied, but he remained calm. “No, not yet. But we can make one within an hour. Just a network you can hide in your hair. A small instrument that will produce minute electric currents. It can be sewn inside the collar of your spacesuit. I’ll give you one more hour now. I would give you more, but with each additional hour their chances of rescue grow less. They’re small enough to begin with. When will you reach a decision?”
“I have already made up my mind.”
“Don’t be foolish, son. Didn’t you hear what I just said? What I told you earlier was only to make you understand that we must not yet take off from this planet.”
“You know I’m going to go.”
“You won’t go if I don’t permit it. Don’t forget that I am still commander of this ship. We are facing a problem here and any personal ambitions must take second place to it.”
“I see,” said Rohan. “You don’t want me to feel that I have been pressured into this. All right. Is our first agreement still valid for what we are discussing now?”
“Yes.”
“Then I would like to know what you would do in my place. Let’s change roles now…”
Horpach remained silent for a while.
“And if I said that I wouldn’t go?”
“Then I won’t go either. But I know that you will speak the truth.”
“Then you wouldn’t go either? Word of honor? No, no… I know that won’t be necessary.”
The astrogator rose from his chair.
Rohan, too, stood up. “You haven’t answered my question.”
The astrogator looked at him. He was taller, more powerfully built, broader across the shoulders. His eyes had the same tired expression they had held at the beginning of the conversation.
“You can go,” he said.
Rohan automatically pulled himself up and turned toward the door. At this moment the astrogator made a movement, as if he wanted to hold him back, seize his arm, but Rohan did not notice it. He left the room, and Horpach remained motionless at the door. He stood this way for a long time.
THE INVINCIBLE
Before daybreak the first two cross-country vehicles rolled down the ramp. The slopes of the dunes toward the sunny side were still black, lying in the shadow of nocturnal darkness. The force field opened up, letting the machines pass through, and closed once more with blue lights twinkling in the night. On the posterior running board of the third vehicle, directly beneath the tail end of the space cruiser, sat Rohan, wearing a spacesuit, but without his helmet and goggles, only with the small oxygen mask before his mouth. He clasped his knees with his hands, for this way it was easier to observe the jumping second hand of his watch.
In the left breast pocket of his protective suit he had stashed away four vials, in the right pocket thin wafers of concentrated food, and the pockets of his knee protectors held small instruments: a radiation counter, a small magnetic watch, a compass, and a microphotogram map of the terrain, smaller than a postcard, which could be read only with a strong magnifying lens. Wound around his waist was a six-ply roll of the finest nylon rope. All metal parts had been removed from his clothing. He could not feel the wire netting hidden in his hair, unless he moved his scalp on purpose. Neither could he feel the current flowing through the net, but he was able to control the micro- sender, sewn inside his collar, by placing his finger on that spot. The small, hard cylinder kept ticking evenly, and he could feel it throb clearly when he touched it.
There was a red streak in the eastern sky. A strong breeze had sprung up. The wind whipped the sandy crests of the dunes. The low-lying, jagged crater rims on the horizon seemed gradually to dissolve in a flood of red. Rohan lifted his head. There was to be no two-way communication between him and the spaceship, since a sender would have given away his presence at once. However, inside, in his ear, was a tiny receiver, no larger than a cherry stone. The
