“Of course you’re interested,” said Blades to Lieutenant Ziska. “I’ll show you some gimmicks I thought up myself.”
Chung scowled at him. “We’d best divide the party and proceed along alternate routes,” he said, “We’ll meet again in the mess for coffee, Lieutenant Ziska, would you like to—”
“Come with me? Certainly,” Blades said.
Chung’s glance became downright murderous. “I thought—” he began.
“Sure.” Blades nodded vigorously. “You being the senior partner, you’ll take the highest ranking of these gentlemen, and I’ll be in Scotland before you. C’mon, let’s get started. May I?” He offered the quartermistress his arm. She smiled and took it. He supposed that eight or ten of her fellows trailed them.
The first disturbing note was sounded on the verandah.
They had glanced at the cavelike dormitories where most of the personnel lived; at the recreation dome topside which made the life tolerable; at kitchen, sick bay, and the other service facilities; at the hydroponic tanks and yeast vats which supplied much of the Station’s food; at the tiny cabins scooped out for the top engineers and the married couples. Before leaving this end of the asteroid, Blades took his group to the verandah. It was a clear dome jutting from the surface, softly lighted, furnished as a primitive officers’ lounge, open to a view of half the sky.
“Oh-h,” murmured Ellen Ziska. Unconsciously she moved closer to Blades.
Young Lieutenant Commander Gilbertson gave her a somewhat jaundiced look. “You’ve seen deep space often enough before,” he said.
“Through a port or a helmet.” Her eyes glimmered enormous in the dusk. “Never like this.”
The stars crowded close in their wintry myriads. The galactic belt glistened, diamond against infinite darkness. Vision toppled endlessly outward, toward the far mysterious shimmer of the Andromeda Nebula; silence was not a mere absence of noise, but a majestic presence, the seething of suns.
“What about the observation terrace at Leyburg?” Gilbertson challenged.
“That was different,” Ellen Ziska said. “Everything was safe and civilized. This is like being on the edge of creation.”
Blades could see why Goddard House had so long resisted the inclusion of female officers on ships of the line, despite political pressure at home and the Russian example abroad. He was glad they’d finally given in. Now if only he could build himself up as a dashing, romantic type… But how long would the Altair stay? Her stopover seemed quite extended already, for a casual visit in the course of a routine patrol cruise. He’d have to work fast.
“Yes, we are pretty isolated,” he said. “The Jupiter ships just unload their balloons, pick up the empties, and head right back for another cargo.”
“I don’t understand how you can found an industry here, when your raw materials only arrive at conjunction,” Ellen said.
“Things will be different once we’re in full operation,” Blades assured her. “Then we’ll be doing enough business to pay for a steady input, transshipped from whatever depot is nearest Jupiter at any given time.”
“You’ve actually built this simply to process… gas?” Gilbertson interposed. Blades didn’t know whether he was being sarcastic or asking a genuine question. It was astonishing how ignorant Earthsiders, even space- traveling Earthsiders, often were about such matters.
“Jovian gas is rich stuff,” he explained. “Chiefly hydrogen and helium, of course; but the scoopships separate out most of that during a pickup. The rest is ammonia, water, methane, a dozen important organics, including some of the damn… doggonedest metallic complexes you ever heard of. We need them as the basis of a chemosynthetic industry, which we need for survival, which we need if we’re to get the minerals that were the reason for colonizing the Belt in the first place.” He waved his hand at the sky. “When we really get going, we’ll attract settlement. This asteroid has companions, waiting for people to come and mine them. Homeships and orbital stations will be built. In ten years there’ll be quite a little city clustered around the Sword.”
“It’s happened before,” nodded tight-faced Commander Warburton of Gunnery Control.
“It’s going to happen a lot oftener,” Blades said enthusiastically. “The Belt’s going to grow!” He aimed his words at Ellen. “This is the real frontier. The planets will never amount to much. It’s actually harder to maintain human-type conditions on so big a mass, with a useless atmosphere around you, than on a lump in space like this. And the gravity wells are so deep. Even given nuclear power, the energy cost of really exploiting a planet is prohibitive. Besides which, the choice minerals are buried under kilometers of rock. On a metallic asteroid, you can find almost everything you want directly under your feet. No limit to what you can do.”
“But your own energy expenditure—” Gilbertson objected.
“That’s no problem.” As if on cue, the worldlet’s spin brought the sun into sight. Tiny but intolerably brilliant, it flooded the dome with harsh radiance. Blades lowered the blinds on that side. He pointed in the opposite direction, toward several sparks of equal brightness that had manifested themselves.
“Hundred-meter parabolic mirrors,” he said. “Easy to make; you spray a thin metallic coat on a plastic backing. They’re in orbit around us, each with a small geegee unit to control drift and keep it aimed directly at the sun. The focused radiation charges heavy-duty accumulators, which we then collect and use for our power source in all our mobile work.”
“Do you mean you haven’t any nuclear generator?” asked Warburton.
He seemed curiously intent about it. Blades wondered why, but nodded. “That’s correct. We don’t want one. Too dangerous for us. Nor is it necessary. Even at this distance from the sun, and allowing for assorted inefficiencies, a mirror supplies better than five hundred kilowatts, twenty-four hours a day, year after year, absolutely free.”
“Hm-m-m. Yes.” Warburton’s lean head turned slowly about, to rake Blades with a look of calculation. “I understand that’s the normal power system in Stations of this type. But we didn’t know if it was used in your case, too.”
Why should you care? Blades thought.
He shoved aside his faint unease and urged Ellen toward the dome railing. “Maybe we can spot your ship, Lieutenant, uh, Miss Ziska. Here’s a telescope. Let me see, her orbit ought to run about so….”
He hunted until the Altair swam into the viewfield. At this distance the spheroid looked like a tiny crescent moon, dully painted; but he could make out the sinister shapes of a rifle turret and a couple of missile launchers. “Have a look,” he invited. Her hair tickled his nose, brushing past him. It had a delightful sunny odor.
“How small she seems,” the girl said, with the same note of wonder as before. “And how huge when you’re aboard.”
Big, all right, Blades knew, and loaded to the hatches with nuclear hellfire. But not massive. A civilian spaceship carried meteor plating, but since that was about as useful as wet cardboard against modern weapons, warcraft sacrificed it for the sake of mobility. The self-sealing hull was thin magnesium, the outer shell periodically renewed as cosmic sand eroded it.
“I’m not surprised we orbited, instead of docking,” Ellen remarked. “We’d have butted against your radar and bellied into your control tower.”
“Well, actually, no,” said Blades. “Even half finished, our dock’s big enough to accommodate you, as you’ll see today. Don’t forget, we anticipate a lot of traffic in the future. I’m puzzled why you didn’t accept our invitation to use it.”
“Doctrine!” Warburton clipped.
The sun came past the blind and touched the officers’ faces with incandescence. Did some look startled, one or two open their mouths as if to protest and then snap them shut again at a warning look? Blades’ spine tingled. I never heard of any such doctrine, he thought, least of all when a North American ship drops in on a North American Station.
“Is… er… is there some international crisis brewing?” he inquired.
“Why, no.” Ellen straightened from the telescope. “I’d say relations have seldom been as good as they are now. What makes you ask?”
“Well, the reason your captain didn’t—”
“Never mind,” Warburton said. “We’d better continue the tour, if you please.”
Blades filed his misgivings for later reference. He might have fretted immediately, but Ellen Ziska’s presence
