Lawrence watched the screen as the Moray grew from a silver speck to a fully defined ship. It was three hundred meters long, and about as basic as any space vehicle could get. Habitation cabins were five cylinders clustered together, thirty-five meters long, eight wide. They'd been sprayed with a half-meter layer of carbon- based foam, which was supposed to act as a thermal shield as well as providing protection from cosmic radiation. Lawrence had checked the solarwatch bulletin before they took off. Sunspot activity was moderate with several new disturbances forming, one of them quite large. He hadn't told the rest of the platoon, but he was quietly relieved the transfer would take only thirty hours. He didn't trust the foam to protect him from anything serious. Its original white coloring had darkened to pewter gray as the years of vacuum exposure boiled the surface, and even with the spaceplane camera's poor resolution he could see pocks and scars from micrometeorite impacts.
Behind the cylinders was a life support deck, a clump of tanks, filter mechanisms and heat exchangers. A broad collar of silver heat-radiator panels stretched out from the circumference, each segment angled to keep the flat surface away from direct sunlight.
Next was the freight section, a fat trellis of girders sprouting a multitude of loading pins, clamps and environmental maintenance sockets. For the last three weeks, the Cairns base spaceplanes had been boosting cargo pods up to the Moray and its sister ships. They'd been ferrying them up to Centralis at the Lagrange four orbital point where the star-ships waited, then returning to low Earth orbit for more. Even now there wasn't a single unoccupied clamp. They contained the helicopters, jeeps, equipment, armaments and supplies for the Third Fleet's ground forces; everything they'd need to mount a successful mission.
The final section of the ship was given over to propulsion. It housed two small tokamak fusion reactors and their associated support machinery, a tightly packed three-dimensional maze of tanks, cryostats, superconductor magnets, plasma inductors, pumps, electron injectors and high-voltage cabling. The fifteen heat radiator panels necessary to cope with the system were over a hundred meters long, sticking out from the ship like giant propeller blades. The tokamaks fed their power into a high-thrust ion drive, eight grid nozzles buried in a simple box structure that was fixed to the base of the ship almost as an afterthought.
Moray's length drifted past the camera as the Xianti gently maneuvered itself to the docking tower at the front. Reaction control engines drummed incessantly, turning the spaceplane along its axis as it was nudged ever closer. Then the airlock rings were aligned, snapping together with a clang.
Lawrence took a look around the cabin. Several squaddies had thrown up, and the larger air grilles along the ceiling and floor were splattered with the residue. Checking his own platoon he could see several of them showing signs of queasiness. Hal, of course, had an expression of utter delight on his face. Zero-G didn't seem to have any adverse effect on him at all. Typical, Lawrence thought; he could already feel his own face puffing up as fluids began to pool in his flesh.
The airlock hatch swung open, and the cabin PA hissed on. 'Okay, we're docked and secure,' the human pilot said. 'You can egress the transorbital now.'
Lawrence waited until the platoon sitting in front of him had gone through the airlock before releasing his own straps. 'Remember to move slowly,' he reminded his people. 'You've got a lot of inertia to contend with.'
They did as they were told, unbuckling the restraints and gingerly easing themselves out of the deep seats. It had been over eighteen months since any of them had been in freefall, and it showed—sluggish movements suddenly becoming wild spins. Desperate grabs. Elbows thudding painfully into lockers and seat corners. Lawrence Velcroed his bag to his chest, and used the inset handles along the ceiling to make his way forward. In his mind, he tried to match the process with climbing a ladder. A good grounding psychology: always try for a solid visual reference. Except here his legs wanted to slide out to the side and twist him around. His abdominal muscles tensed, trying to keep his body straight. Someone knocked into his feet. When he glanced around to glare, Odel Cureton was grimacing in apology, his own body levering around his tenuous handhold, putting a lot of strain on his wrists.
'Sorry, Sarge.' It was a fast grunt. Odel was trying not to puke.
Lawrence moved a little faster, remembering to kill his motion just before he reached the airlock. He slithered easily around the corner and through the hatch, pleased with the way the old reflexes were coming back.
The Moray was as crude inside as it was outside, stark aluminum bulkheads threaded with dozens of pipes and conduits, hand loops bristling everywhere. The air reeked of urine and chlorine. It must have been strong: Lawrence's sense of smell was fast diminishing beneath clogged sinuses. One of the crew was waiting for him on the other side of the airlock. Lawrence gave him their platoon number, and in return was told what berth they'd been assigned. Each of the big habitation cylinders was color coded. Lawrence led the cursing, clumsy platoon down into the yellow one. Voices echoed about him, coming from open hatchways—other platoons bitching about the conditions and how ill some of their buddies were and why didn't someone do something about bastard freefall. Twice Lawrence banged himself on the walls as they scrambled their way along the central tubular passageway; elbow and knee. By the time he slipped into their compartment he could feel the bruises rising.
The others crawled in after him, moaning and wincing, looking round sullenly. Their compartment was a simple wedge shape. It had three rows of couch chairs with simple hold-you-down straps, a pair of freefall toilets, a locker full of packaged no-crumble meals, a microwave slot and a water fountain with four long hoses ending in stainless-steel valves. Someone had written: Don't even think about it on the aluminum concertina door of one toilet. What would become the ceiling when the ion drive was running was covered with a sheet screen. It was orientated so that anyone in the chair couches would have a reasonable view. A Z-B strategic security logo glowed faintly in the center purple omega symbol bracketing the earth, crowned by five stars.
Hal stowed his bag and flew across the compartment, turning a fast somersault on the way. 'This is fucking amazing. Hey, what kind of i-media are they going to give us, anyone know?'
'You don't get i-media in a crate like this,' Odel said in exasperation. 'This isn't a pleasure cruise, kid. You worked that out yet? You'll be lucky if they've got black-and-white films.' He put his glasses on, leaving the display lenses clear, but settling the audio plugs in his ears. Thin vertical scarlet lines appeared on the lenses as he called up a menu. He worked down a playlist of rock tracks from centuries-old classics right up to Beefbat and Tojo Wall, then settled back contentedly as they began to play.
Lawrence sighed, fastening himself loosely into one of the couch chairs. It could have been worse. Some platoons had boosted out of Cairns ten days ago. At least he only had another four days until the Third Fleet departed from Centralis. Perhaps they could put something in the kid's food.

Simon Roderick went down to the observation gallery half an hour before the portal opening. There were over a hundred people crammed into the small chamber protruding from the surface of Centralis. Somehow they contrived to give him a little patch of free space in front of the thick glass where he could stand by himself. They were silent, though Simon could sense their minds spiking with resentment and disquiet. As always, he ignored their pusillanimous nature with his usual contempt. The physical discomfort of Centralis itself couldn't be dismissed quite so easily, however.
Centrifugal force didn't make him giddy, although he often caught himself wishing for a full one-gravity field.
Centralis was too small for that, its rotation producing slightly less than two-thirds of a gee around its outermost level.
Back in the mid-1970s when Gerard K. O'Neill was putting his High Frontier concept together he produced several designs for space 'islands.' Starting with the simple Bernal sphere at four hundred meters in diameter, the concepts progressed up to the paradise garden of 'Island Three': linked twin cylinders twenty kilometers long. All of them were admittedly achievable with relatively simple engineering procedures. The problem came in gathering together that much material with the requisite construction crews and their assembly equipment in an era when it cost upward of two hundred million U.S. dollars to launch a single space shuttle.
Scramjet spaceplanes eased the problem of cheaper access to space. But as they helped to build low-orbit stations and their associated industrial modules, so they reduced the need for vast habitats. Even in a rampant consumer society, the quantity of ultraspecialist crystals and chemicals that could be produced only in microgee facilities was limited to a few hundred metric tons a year—a figure easily supervised by small tough crews paid exorbitant salaries to endure the generally unpleasant conditions to be found in Earth-orbit space stations.
It was only in 2070, when a method of faster-than-light travel was developed, that there was any need for large high-orbit dormitory towns. Starships were neither compact nor cheap: they needed thousands of people to construct the massive superstructure and integrate hundreds of thousands of components into a functional whole. As they were too big to take off or land on a planet, they had to be built in space. O'Neill's old ideas were pulled out of university libraries and studied afresh.
