"You do that, Mother. I'm not worrying. Jon really knows his stuff," Jak assured her brightly. But as soon as she had left the control room, he turned worried eyes to his brother. "I ... I hope you actually do, Chubby." His voice quavered a bit.
Jon grinned mockingly. "There's one sure thing. If I'm wrong, we'll never know it. But I've studied this a lot since I knew it was up to me. I know the technique and, as I said before, I've computed our course three times and come up with the same figures each time. And we have to set it as close as possible. Now, either hit your bunk or set your seat to recline. We're up to better than two G's already, and I'm building to five."
"Yes, I feel us getting heavier. I'll stay with you." Jak made sure his straps were in place, then tilted his seat.
Jon cranked his own to recline, the control panel automatically slanting to keep it in the same relative position. His arms were resting on movable slides, and the controls he would have to manipulate on this dangerous orbit were all beneath his hands and fingers.
Closer and closer they drove to the sun with ever mounting speed. Their gallant little ship's refrigerators were full on; all shutters in place. Their only view of the outside was through one visiplate whose aperture was closed until only a tiny slit was open. But it was enough, although Jon was forced to keep building up layer after layer of protective, colored plastic to make the intense, blinding light of the swiftly approaching sun bearable.
Clearly visible now were the tremendous streamers of matter the sun was throwing up as prominences. Jon was able to see huge sunspots occurring here and there about the surface of that mighty furnace—tremendous cyclonic storms of atomic disintegration. So interested was he in this first close view of a sun that he almost forgot the reason for this dangerous trip.
Almost—but not quite, for his mind was well-trained to remember the things that had to be recalled, young as he was. So his eyes glanced often at the distance gauge. Soon he yelled at Jak, "Get ready to throw out the sender."
Jak struggled to place his hands on the controls, a thing he had not had the foresight to do before Jon started building up that tremendous acceleration. His muscles strained. Sweat broke out on him even worse than that the heat from the sun brought. His breathing became gasps. There seemed to be a constricting band about his chest. His eyes felt as though the balls were being pushed down into his head. He just couldn't possibly move a muscle under this terrible pressure.
Still he exerted every force of will and of muscle. Slowly, painfully, he stretched out his fingertips a fraction of an inch. He dug them into the fabric of the arm rest and pulled the palm of his hand along. Then he forced the rest of his arm to follow his fingers and hand. Over and over, straining to do what had to be done. Then victory at last—his hand and arm were on the sliding arms. Now it was easier, and soon his fingers were on the controls.
"S-say when," he panted then.
