Flight Officer Ozaki was taking a catnap when the alarm on the radiation detector went off. Dashing the sleep out of his eyes, he slipped rapidly into the control seat and cut off the gong. His fingers danced over the controls in a blur of movement. Swiftly the vision screen shifted until the little green dot that indicated a source of radiant energy was firmly centered. Next he switched on the pulse analyzer and watched carefully as it broke down the incoming signal into components and sent them surging across the scope in the form of sharp-toothed sine waves. There was an odd peak to them, a strength and sharpness that he hadn’t seen before.
“Doesn’t look familiar,” he muttered to himself, “but I’d better check to make sure.”
He punched the comparison button and while the analyzer methodically began to check the incoming trace against the known patterns stored up in its compact little memory bank, he turned back to the vision screen. He switched on high magnification and the system rushed toward him. It expanded from a single pinpoint of light into a distinct planetary system. At its center a giant dying sun expanded on the plate like a malignant red eye. As he watched, the green dot moved appreciably, a thin red line stretching out behind it to indicate its course from point of first detection. Ozaki’s fingers moved over the controls and a broken line of white light came into being on the screen. With careful adjustments he moved it up toward the green track left by the crawling red dot When he had an exact overlay, he carefully moved the line back along the course that the energy emitter had followed prior to detection.
Ozaki was tense. It looked as if he might have something. He gave a sudden whoop of excitement as the broken white line intersected the orange dot of a planetary mass. A vision of the promised thirty-day leave and six months’ extra pay danced before his eyes as he waited for the pulse analyzer to clear.
“Home!” he thought ecstatically. “Home and unplugged plumbing!”
With a final whir of relays the analyzer clucked like a contented chicken and dropped an identity card out of its emission slot. Ozaki grabbed it and scanned it eagerly. At the top was printed in red, “Identity. Unknown,” and below in smaller letters, “Suggest check of trace pattern on base analyzer.” He gave a sudden whistle as his eyes caught the energy utilization index. 927! That was fifty points higher than it had any right to be. The best tech in the Protectorate considered himself lucky if he could tune a propulsion unit so that it delivered a thrust of forty-five per cent of rated maximum. Whatever was out there was hot! Too hot for one man to handle alone. With quick decision he punched the transmission key of his space communicator and sent a call winging back to War Base Three.
