The light plates set into the control room walls made a soft glow. Air came through the tiny grills in a sound like an endless sigh.
The entire control room was mounted on a shining piston that went straight down through the heart of the ship. The partitioned space along one wall, forty feet by ten, held the row of beds. Beyond the opposite partition were food stores, water tanks, sanitary equipment.
Leesa lay on the bunk and he folded the web straps across her body, drawing them tight. The last strap circled her forehead.
She looked up into his eyes. “Are we really ready?”
“We have to be. And I’ll make a confession. If all this hadn’t happened, I was going to try it alone, without you.”
“Maybe,” she said softly, “this is all just another dream, Raul. A more clever dream. Can you find Earth?”
“I know the number for Earth. I’ll set it the way Bard Lane explained. And then, quite soon, we’ll know.”
“Promise me one thing.”
He looked down at her. “What is it?”
“If we are wrong. If there are no worlds out there. Or if we lose our way, I want to die. Quickly. Promise?”
“I promise.”
He slid the partition shut and went to the control panel. His pilot’s couch was on rails so that, once he was in place, he could slide it forward under the vertical panel and lock himself in place. He strapped his ankles and his waist and pushed himself under to lie looking up at the controls. He activated the three-dimensional screen. There were the six ships, the tall white world, the sandy plain and the hills. He opened the book and took a last look at the reference number for Earth even though it had long since been memorized. He set the ten-digit number, six plus values and four minus ones, on the ten dials, checked it again. The replica ship was in neutral position. Only then did he strap the diaphragms firmly to his throat. He pulled the headband up and tightened it, slid his arms down into the straps.
And softly as he could, he made the vowel sound. The ship shuddered, trembled. On the screen the tiny image moved slowly upward, upward. Now the stern was as high as the bows of the other ships. He strengthened the vowel tone and the replica ship remained in the middle of the screen, the planet moving away below it, the curvature beginning to show, the white tower world dwindling.
He rashly strengthened his tone once more. A vast weight pressed his jaw open, punched down on his belly, blinded him by pressing his eyes back into his head. He heard, from a great distance, Leesa’s scream of pain. He ceased all sound. The pressure slowly left him. He was dizzy with weightlessness. His home planet had shrunk to the size of a fist. It appeared in the lower right-hand corner of the screen and the image of the ship had dwindled until it was a bright mote against the darkening screen.
He took a weightless arm out of the strap, thumbed the knurled knob at the side of the screen. His planet slid off the screen and, by experimentation, he made the ship image grow larger. He moved close to it. The opposite knob seemed to rotate the ship itself end for end, but he realized that it merely shifted the point of vision. He adjusted it until he was looking forward from dead astern of the ship. The vast disc of the sun was straight ahead. He moved his hand to the replica ship and turned it through a ninety-degree arc to the right. As the sun slid off the screen, the replica ship moved slowly back to neutral. The screen showed distant spots of light against the utter blackness. He began to make the vowel sound again, cautiously at first, running it each time up to the limits of endurance, then resting in silence as the ship rushed, without noise, through the void. He understood that each time he made the sound he gave it another increment of speed. At last, no matter how loudly he made the sound, he could feel no answering downward thrust and he knew that the top limit had been reached.
Somewhere, ahead, the time setting would take effect. He did not know where. He did not know how long it would be.
