Maybe he’s sent off spacegrams, but no ship could possibly get here in time.”
Cathy shivered a little. “Let’s not think about him. Just about us. We haven’t much time.”
And just then, very strangely, an idea came to Lon Simpson. He tensed.
After a moment, he said in a very queer voice, “This isn’t a nova. It’s a flare-up. The sun isn’t exploding. It’s just too hot, too big for the temperature inside it, and it’s a closed system. So radiation pressure has been building up. Now it’s got to be released. So it will spout geysers of its own substance. They’ll go out over hundreds of thousands of miles. But in a couple of weeks it will be back—nearly—to normal.”
He suddenly knew that. He knew why it was so. He could have explained it completely and precisely. But he didn’t know how he knew. The items that added together were themselves so self evident that he didn’t even wonder how he knew them. They had to be so!
Cathy said muffledly, her face against his shoulder, “But we won’t be alive in a couple of weeks, Lon. We can’t live long past daybreak.”
He did not answer. There were more ideas coming into his mind. He didn’t know where they came from. But again they were such self evident, unquestionable facts that he did not wonder about them. He simply paid tense, desperately concentrated attention as they formed themselves.
“We—may live,” he said shakily. “There’s an ionosphere up at the top of the atmosphere here, just like there is on Earth. It’s made by the sunlight ionizing the thin air. The—stronger sunlight will multiply the ionization. There’ll be an—actually conducting layer of air.... Yes.... The air will become a conductor, up there.” He wet his lips. “If I make a—gadget to—short-circuit that conducting layer to the ground here.... When radiation photons penetrate a transparent conductor—but there aren’t any transparent conductors—the photons will—follow the three-finger rule....
“They’ll move at right angles to their former course—”
He swallowed. Then he got up very quietly. He put her aside. He went to his tool shed. He climbed to the roof of the barn now filled with thanar leaves. He swung his axe.
The barn was roofed with aluminum over malleable plastic. The useful property of malleable plastic is that it does not yield to steady pressure, but does yield to shock. It will stay in shape indefinitely under a load, but one can tap it easily into any form one desires.
Lon swung his axe, head down. Presently he asked Cathy to climb up a ladder and hold a lantern for him. He didn’t need light for the rough work—the burning desert vegetation gave enough for that. But when one wants to make a parabolic reflector by tapping with an axe, one needs light for the finer part of the job.
In Cetopolis, Carson agitatedly put his records on tape and sent it all off by spacegram. He’d previously reported on Lon Simpson, but now he knew that he was going to die. And he followed his instinct to transmit all his quite useless records, in order that his superiors might realize he had been an admirable employee. It did not occur to him that his superiors might be trying frantically to break his sending beam to demand that he find out how Lon Simpson made his power gadget and how he converted vegetation, before it was too late. They didn’t succeed in breaking his beam, because Carson kept it busy.
He was true to type.
Elsewhere, other men were true to type, too. The human population of Cetis Gamma Two was very small. There were less than five thousand people on the planet—all within a hundred miles of Cetopolis, and all now on the night side. The rest of the planet’s land masses scorched and shriveled and burst into flame where the sun struck them. The few small oceans heated and their surfaces even boiled. But nobody saw it. The local fauna and flora died over the space of continents.
But in the human settlement area, people acted according to their individual natures. Some few ran amok and tried to destroy everything—including themselves—before the blazing sun could return to do it. More sat in stunned silence, waiting for doom. A few dug desperately, trying to excavate caves or pits in which they or their wives or children could be safe....
But Lon pounded at his barn roof. He made a roughly parabolic mirror some three yards across. He stripped off aluminum siding and made a connection with the ground. He poured water around that connection. He built a crude multiply twisted device of copper wire and put it in the focus of the parabolic mirror.
He looked up at the sky. The stars seemed dimmer. He took the copper thing away, and they brightened a little. He carefully adjusted it until the stars were at their dimmest.
He descended to the ground again. He felt an odd incredulity about what he’d done. He didn’t doubt that it would work. He was simply unable to understand how he’d thought of it.
“There, darling! Your pets are quite safe!” Rhadampsicus said pleasedly.
Nodalictha scanned the second planet. It was apparently coated with a metallic covering. But it was not quite like metal. It was misty, like an unsubstantial barrier to light—and to Nodalictha’s penetrating thoughts.
“I had your male pet,” Rhadampsicus explained tenderly, “set up a power beam link to the ionosphere. With several times the usual degree of ionization—because of the flaring sun—the grounded ionosphere became a Rhinthak screen about the planet. The more active the sun, the more dense the screen. They’ll have light to see by when their side of the planet is toward the sun, but no harmful radiation can get down to them. And the screen will fade away as the sun goes back to its normal state.”
Nodalictha rejoiced. Then she was a little distressed.
“But now I can’t watch them!” she pouted. Rhadampsicus watched her gravely. She said ruefully, “I see, Rhadampsicus. You’ve spoiled me! But if I can’t watch them for the time being, I won’t have anything to occupy me. Darling Rhadampsicus, you must talk to me sometimes!”
He talked to her absorbedly. He seemed to think, however, that discussion of the local solar phenomena was conversation. With feminine guile, she pretended to be satisfied, but presently she went back to her housekeeping. She began to dream of their life when they had returned home, and of the residence they would inhabit there. Presently she was planning the parties she would give as a young matron, with canapés of krypton snow and zenon ice, with sprinklings of lovely red nickel bromide crystals for a garnish—
The sun rose again, and they lived. It was as if the sky were covered with a thick cloud bank which absorbed the monstrous radiation of a sun now four times its previous diameter and madly changing shape like a monstrous ameba of flame.
In time the sun set. It rose again. It set. And Cetis Gamma Two remained a living planet instead of being a scorched cinder.
When four days had gone by and nobody died, the colonists decided that they might actually keep on living. They had at first no especially logical foundation for their belief.
But Cathy boasted. And she boasted in Cetopolis. Since they were going to keep on living, the conventions required that she return to the planet’s one human settlement and her duties as a beamphone operator. It wasn’t proper for her to stay unchaperoned so long as she and Lon weren’t married yet.
She had no difficulty with Carson. He didn’t refer to her desertion. Carson had his own troubles. Now that he had decided that he would live, his problems multiplied. The colonists’ barns were filled to capacity
