Science equipped David Corbin with borrowed time sent him winging out in a state of suspension to future centuries ... to a dark blue world whose only defense was to seal tight the prying minds of foolish interlopers.

It was space. I looked out at deep space, star systems in clusters. I shut my eyes. When I looked again I knew where I was. Why the little room had been David Corbin. I knew more of the puzzle. Something was wrong. After the first shock of looking out, I accepted the fact that I was in a space ship, yet I couldn't read the maps that were fastened to a table, nor understand the function or design of the compact machinery. WHY, Why, Why? The thought kept pounding at me. I was afraid to touch "It is assumed the experiment is a success," the voice said. ship." Control of a ship? Going where? "Do not begin operations until the others are removed from suspension." What others? Tell me what to do. "Rely on instructions for factoring when you check the coordinates. emergency procedures as you see fit. Good luck." others. A flat, illogical voice had instructed me to revive these men. I into the doors in the passageway and went back to the room with the portholes. Everything lay in readiness, fastened down star charts, instruments, glittering equipment. There was no feeling of disorder or use in the room. It waited for human hands to make it operate. the reason for that dependence. I sat beside her on the cot until I could stand it no longer. Searching the ship made me forget my fear. I hoped I would find some floating motion, looking behind each door until I went as far as I could. There were two levels to the ship. They both ended in the lead the engine or engines took up half the ship, cut off from the forward rough estimate of size. The ship, as I called it, was at least four had literally been reborn in this room, equipped with half ideas, and no point to start from, no premise to seek. I sensed the place to start from was back in the room. I searched it carefully. my fingers over the unbroken surface, prying over the thin crack at the base helplessly. If some sort of antidote was to be administered manually I was lost. I had no knowledge of what to inject or where to That meant a measured amount. In the laboratory on the lower level I went over the rows of cans and tubes fastened to the shelves. There were earths and minerals, seeds and chemicals, testing equipment in compact drawers, but nothing marked for me. I wondered if I was an engineer or a pilot, or perhaps a doctor with the ship was a frightening force that seemed ready to break out of "Who is in charge of this ship?" I asked. name or anything about this ship." "What about her. Why is she here?" I asked my companion. He lifted the cover from the apparatus. "She's the chemist in the crew." "It's a bad thing to do." "I suppose. The mission stated one chemist." "What is the mission of this ship?" I asked. He held up his hand. "We'd better wait, sir. Everything was supposed to "John, what are your duties if any?" "Can you run this ship? How about the other two?" He hit his hands together. "You fly it, sir. Can't you think?" "I'm trying. I know the ship is familiar, but I've looked it over. Maybe I'm trying too hard." "You flew her from earth until we went into suspension," he said. better for being together. John Croft named the others for me. I for any of us, we'll stop. John, you can lead off." "You ask the questions," he said. I indicated the ship. "Where in creation are we going?" "We set out from Earth for a single star in the direction of the center of our Galaxy." "From Earth? How could we?" "Let's move slowly, sir," he said. "We're moving fast. I don't know if you can picture it, but we're going about one hundred thousand miles an hour." "Through space?" "Yes." "What direction?" Paul cut in. "It's a G type star, like our own sun in mass and luminosity. We hope to find a planetary system capable of supporting life." "I can't grasp it. How can we go very far in a lifetime?" "It can be done in two lifetimes," John said quietly. "You said I had flown this ship. You meant before this suspension." "Yes. That's why we can cross space to a near star." "How long ago was it?" "It was set at about a hundred years, sir. Doesn't that fit at all?" "I can't believe it's possible." Carl caught my eye. "Captain, we save this time without aging at all. It puts us near a calculated destination." right if you don't lose your nerve." "What are we to do?" she asked. John answered for me. "First we've got to find out where we are. I know this ship but I can't fly it." "Can I?" I asked. We set up a temporary plan of action. Paul took Karen to the laboratory rations. I was to study the charts and manuals. It was better than doing nothing, and I went into the navigation room and sat down. Earth was an infinitesimal point somewhere behind us on the galactic plane, and no one else was trained to navigate. The ship thundered to life as I "We can't spare any, can we?" I asked. "I wish we knew. What about her—Dr. Thiesen?" "She's in the lab. I don't think that will do much good. She's got to room. "Turn the ship. There's something dead ahead." I had a glimpse of his contorted face as I dove at the control board. like warm liquid. I hung on the intercom for support, drawing air into my heaving lungs. sun. I thought about the rest of the crew too. "We're heading right for a star...." the intercom to open. "This is control. Listen ... everyone. I'm over it. Disregard the warning siren ... we were testing the ship." The lab light blinked on as Paul cut in. "What was it ... hey, you said when you can. I've got to find out where we are." We had to get off course before we ran into the yellow-white star that had been picked for us. Food was set down by me, grew cold and was carried away and I was still rechecking the figures. We were on a line ten degrees above the galactic plane. The parallactic baseline from Earth to the single star could be in error several degrees, or we could distance, the screen glowed to life and recorded the star dead ahead. In all the distant star clusters, only this G type star was thought to have a planetary system like our own. We were out on a gamble to find a planet capable of supporting life. The idea had intrigued scientists before I had first looked up at the night sky. When I was sure the electronically recorded course was accurate for time, I checked the screen gave us the distance and size of the star while we fed the figures into the calculator for our rate of approach. Spectroscopic tests were run on the sun and checked against the figures that had been calculated on Earth. We analyzed temperature, magnetic fields, radial motion, density and luminosity, checking against the standards the scientists had constructed. It was a G type star like our own. It had more density and temperature and suitable planets or not, we had to change course in a hurry. Carl analyzed the findings while we came to a decision. Somewhere along an orbit that might be two hundred miles across, our hypothetical planet circled this star. That distance was selected when the planets in Earth's solar system had proved to be barren. If the observations on this star were correct, we could expect to find a planet in a state of fertility ... if it existed ... if it were suitable for colonization ... if we could find it.
