Because he was used to more modern consoles, Pirx’s head kept turning in the wrong direction every time he went to check the thrust performance, cooling, velocity, thermal load, and, most important, their position relative to the synergic curve.
The pilot, who had to scream over the intercom to make himself heard, was having trouble keeping on course. True, they were only fractional deviations, but that was all it took, when escaping Earth’s atmosphere, to make one side heat up more than the other, setting up powerful thermal stresses in the outer structure, often with fatal consequences. Pirx’s only consolation was that the Star had survived plenty of other lift-offs in the past; chances were, it would make this one as well.
The thermocouple was now on maximum: 3,500 degrees. Ten more minutes of this and the hull would come apart at the seams, carbide or no carbide. What gauge was the skin? he wondered. No telling—except that it was, for sure, hot. He felt warmer himself, but it was only his imagination: the temperature in the control room was the same as at lift-off: 27 degrees. They were at the 61-kilometer mark, Earth’s atmosphere practically behind them, flying at a velocity of 7.4 kilometers per second, with less turbulence but still at 3g. The Star had as much oomph as a block of lead, its rapid acceleration nil. Damned if he could understand why.
A half hour later they were steering a course for the Arbiter; once past the last navigational satellite, they would be veering onto the Earth-Mars ellipsis. The crew was sitting up now; Boman was massaging his face; Pirx, too, felt swollen around the mouth, especially in the region of the lower lip. Everyone had bloodshot, stinging eyes, a dry cough, and a sore throat—all the usual symptoms, normally disappearing with-in an hour.
The reactor was working, but that was about all; if its performance didn’t decrease, neither did it increase, as well it should have in a vacuum. The Star appeared to defy even the laws of physics. They were up to 11 kilometers per second, barely above escape velocity. They would have to bring her up to cruising speed if they didn’t want to take months getting to Mars.
Pirx, like every other navigator, was expecting nothing but hassles from the Arbiter. Like getting reprimanded for having too big an exhaust flare, or getting bumped to make way for some more important mission, or hearing complaints about how his ionization discharge was causing radio interference. A false alarm. The Arbiter let them through without a boo, just a belated radiogram warning of a “high vacuum” ahead. Pirx acknowledged the warning, and thus ended this exchange of cosmic civilities.
As soon as they were locked onto Mars, Pirx ordered an increase in thrust, people got up, stretched, moved about, and the radio mechanic, who also doubled as crew cook, headed off to the galley. Everyone was famished, most of all Pirx, who had flown on an empty stomach and sweated pounds during takeoff.
The temperature in the cockpit was rising, as the heat generated by the shield began to make itself felt inside. There was also a faint odor in the air—the oil that had escaped from the hydraulics and which now formed neat little puddles around the seats.
The nuclear engineer went down to the reactor chamber to check for neutron leakage. Keeping one eye on the stars, Pirx shot the breeze with the ship’s electrician; it turned out they moved in the same crowd. For the first time since coming aboard, Pirx began to unwind, to see the brighter side of things. Whatever else the Star might be, 19,000 tons was nothing to sneeze at. Commanding a clunker that size was a lot tougher than piloting your ordinary freighter. Tougher, yeah, but also more prestigious, a good thing to fatten your dossier with.
They were 1.5 million kilometers out beyond the Arbiter when their morale suffered its first blow: the lunch was unfit for human consumption. The radio mechanic, it turned out, was no cook. But the man with the biggest gripe was the orderly, already nursing an upset stomach. Just before lift-off, the orderly had made a bargain on some chickens, one of which he had entrusted to the mechanic’s culinary art; the result was a broth full of quills. The rest of the crew was served rump steak, tough enough to consume a lifetime of hard labor.
“A little tough, eh?” commented the second pilot, who pronged his meat with such gusto that it flipped off the plate.
The mechanic, who also had a tough skin, told the orderly there was nothing wrong with the broth that a little straining wouldn’t cure. Pirx felt obliged to act as mediator in the dispute, to exercise some authority as the ship’s CO, but he was too choked with laughter to even open his mouth.
After a canned lunch, Pirx moseyed on back to the cockpit. He had the pilot take a star fix, entered the accelerometer readings in the log, and whistled when his glance landed on the reactor gauge. That was no reactor, brother—that was a volcano! Eight hundred degrees in the shielding after only four hours of flight was no laughing matter. Coolant circulated at a maximum pressure of 20 atmospheres. Hm. The worst was probably over. Landing on Mars would be a breeze—thinner atmosphere, with a gravity less than half Earth’s… But the reactor, what to do about the reactor…? He went over to the computer, to calculate how long it would take to reach a cruising velocity at their present rate of thrust. Anything less than 80 kilometers per second would mean a ferocious delay.
“Seventy-eight hours to go,” registered the display.
Seventy-eight hours?! By then the reactor would be blown to bits, splattered like an egg. As sure as his name was Pirx. He decided to build up speed gradually. It’ll mean screwing up the flight plan a little, thought Pirx, it’ll mean going without thrust for a while… it won’t be no joyride without any gravitation… but, well, it’s that or nothing. He told the pilot to keep an eye on the astrocompass, then took the elevator down to the reactor chamber. He was working his way down a dim passageway, with cargo holds to the right and left of him, when he heard something on the order of a hollow drumming—the sound an armored squadron riding over metal might make. He quickened his step. A cat—the same black cat—sprang out of nowhere and squirmed between his legs; not far off, a door banged shut. By the time he reached the cavelike mouth of the main passageway, it was quiet again. Before him lay a desolate stretch of bleakly blackened walls, an emptiness relieved only by a solitary lightbulb at the far end, still jittering from the impact of the slamming door.
“Terminus!” he called out blindly, but he got only an echo in reply. He turned and followed the passageway all the way back to the reactor chamber. Boman, who had already come down earlier on the elevator, was gone. The arid, desertlike air irritated his eyes. A hot wind seethed inside the air ducts, blending with all the boiler-room racket. The reactor was performing like any other reactor—in silence. The noise came from the cooling system, now strained to the maximum—a strangely rueful, yammering whine produced by the kilometers of tubing that circulated the ice-cold liquid deep inside the concrete shielding. The needles on the lenslike gauges of the pumps were uniformly tilted to the right. Standing out prominently from all the others, its dial radiant as the Moon, was the most critical gauge of all: the one measuring neutron flux density. Its indicator was verging on the red, a sight guaranteed to give any SSA inspector cardiac arrest.
The rugged, rocklike surface of the shielding gave off a deadly heat; the catwalk’s sheet-metal construction vibrated, sending unpleasant ripples through his body; the electric lights cast an oily glare on the vent covers. A white light flickered and went out; in its place a red warning signal came on. He ducked under the catwalk to check the timing switches but saw that Boman had already beat him to it; the automatic tinier was programmed to interrupt the chain reaction in four hours. Without tampering with the timer, he checked the gamma-ray counters. They were ticking gingerly away. The radiation monitor indicated a slight leak of 0.3 roentgen per hour. He tossed a glance into the chamber’s darkest corner. Empty.
“Hey, Terminus!”
No answer. The mice fidgeted in their cages—back and forth, like white specks—manifestly miserable in the subtropical temperature. Pirx climbed back up the stairs and bolted the door behind him. He felt a ch
ill the moment he hit the cooler air in the passageway: his shirt was soaked through. On a whim he made his way aft, down a series of passage-ways that kept getting narrower as they approached the tail section, and came to a dead end. He placed one hand on the bulkhead. It was warm. He sighed, retraced his steps, rode the elevator up to the fourth deck, and entered the navigation room. The chronometer showed 2100 hours by the time he had finished plotting the ship’s course. Must have lost track of the time, he thought, a bit bewildered. He hit the lights and went out.
The deck seemed to slide out from under his feet the moment he stepped into the elevator. The timer had shut down the reactor as programmed.
At midships the passageway purred with the steady hum of fans in the subdued lighting. The lightbulbs on ahead smoldered in the circulating air currents. Using the elevator door as a springboard, he propelled himself swimmer-style down the passageway, one side of which was almost totally immersed in darkness. In the bluish haze he passed a series of hatches—hitherto unexplored—and black walls set off by ruby-red lights: the emergency escape hatches. With a fluent, somnolent motion, he glided weightlessly beneath the vaulted ceiling, his elusive, untrodden shadow creeping along the deck, wriggled through a partially open door, and entered the former mess hall. Below him, its surface streaked with light, stretched a long table flanked by chairs. He hung suspended above the furniture like a deep-sea diver exploring the interior of a sunken ship. Lights played in the shimmering panes along the wall before dispersing in a shower of blue sparks. The mess hall opened onto another, even darker room. Though his eyes were accustomed by now to the dark, he had to feel his way, blindly fingering everything as he went. His fingertips brushed something pliable—deck or ceiling, he couldn’t tell. He pushed himself away, twisted around like a swimmer, and glided on in silence. A row of white, geometrically shaped objects sparkled in the velvety darkness. Their smooth surface felt cold to the touch. Washbasins. The one closest to him was flecked with spots. Blood?
He stuck out his hand—cautiously. Grease spots.
A third hatch door. He opened it and, suspended obliquely in space, was confronted by an eerie procession of paper and books fluttering by in the shadowy penumbra before with-drawing with a faint rustling noise. He propelled himself in the opposite direction, using his feet this time, and wound up back in the passageway, hounded by a cloud of dust, which clung to him instead of dispersing—trailed after him like a long, reddish-brown veil.
The string of night-lights burned with a serene calm, inundating the decks with a watery blue shimmer. He swam up to a rope dangling from the ceiling; the moment he let go of the end, it coiled itself up lazily, snakelike, as if suddenly animated by his touch.
His head snapped back. A clunking noise, similar to a hammering on metal, sounded nearby. He swam in the direction of the echoes, their volume now rising, now falling; along the way spotted a set of rusty tracks embedded in the deck—once used for wheeling dollies to and from the holds, he guessed—and soon was sailing along so fast he could feel the air buffeting his face. The clanging kept getting louder. He sighted a pipe angling around the corner from the next passageway and running along the ceiling. A section of old, one-inch pipeline. He touched it with his hand; it jiggled. The resonances now came in clusters of twos and threes. That’s when it hit him. The banging was in Morse.
“A-t-t-e-n-t-i-o-n…”
The series came again:
“A-t-t-e-n-t-i-o-n…”
And again:
“A-t-t-e-n-t-i-o-n…”
Then the pipe chimed, “A-m-b-e-h-i-n-d-b-u-l-k-h-e-a-d.” By force of habit, he spliced the letters together, syllable by syllable.
“I-c-e-e-v-e-r-y-w-h-e-r-e…”
Ice? he wondered, caught completely off guard. What in…? Ice? What ice?
“R-e-a-c-t-o-r-v-e-s-s-e-l-c-r-a-c-k-e-d,” the pipe resonated. He wrapped his hand around it. Who was signaling? And where was it coming from? He tried to figure out which way the pipe ran—from the bow or back aft. If looked like one of those emergency pipelines, obsolete, with branches on ever deck. Maybe someone was practicing his Morse…? That’s crazy. The pilot up in the control room, maybe?
“C-o-m-e-i-n-p-r-a-t-t-c-o-m-e-i-n…”
A pause.
Pirx was breathless. The mention of that name was like a blow to the gut. For a second he stared wide-eyed at the pipe, then suddenly lurched forward. That’s it—the name of that second pilot, he thought as he hit the bend, bounced off, and made for the control room, gathering speed as he went, the pipe all the while reverberating overhead.
“W-a-y-n-e-h-e-r-e-s-i-m-o-n…”
The echoes receded. Pirx momentarily lost sight of the pipe, picked it up again where it swerved into the next passageway, lunged after it, was bounced off the wall by his own momentum, and saw something through the dust cloud: a gnarled stump of metal, fixed with a rusty cap. A pipe bend. Severed. So it came from the tail section, not the cockpit… Huh? There was nobody back aft…
“P-r-a-t-t-i-n-s-i-x-t-h-t-o-l-a-s-t-h-o-l-d…,” the pipe chimed.
He hung like a bat under the ceiling, clutching the pipe with his fingers, and felt the vibrations throbbing in his head. The banging resumed after a short intermission.
“H-i-s-b-o-t-t-l-e-d-o-w-n-t-o-t-h-i-r-t-y-m-i-n-u-s…”
Another series of three.
“C-o-m-e-i-n-m-o-m-s-s-e-n…”
A pause.
He looked around. Dead silence except for a faint whirring noise in one of the fan outlets. The incoming fresh air sent particles of dirt swirling up to the ceiling, where under the light they took on the aspect of misshapen moths. Then came a torrent of clanging, rapid and staccatolike: “P-r-a-t-t-p-r-a-t-t-p-r-a-t-t-m-o-m-s-s-e-n-d-o-e-s-n-t-a-n-s-w-e-r-o-x-y-g-e-n-i-n-n-u-m-b-e-r-s- e-v-e-n-c-a-n-y-o-u-t-r-a-n-s-f-e-r-o-v-e-r…”
A pause. The lighting remained constant; the dust and waste particles continued their pirouette in slow motion. Pirx felt like letting go of the pipe, but something prevented him. He waited. Then it started up again. “S-i-m-o-n-t-o-m-o-m-s-s-e-n-p-r-a-t-t-i-n-n-u-m-b-e-r-s-i-x-b-e-h-i-n-d-b-u-1-k-h-e-a-d-t-o-l-a-s -t-b-o-t-t-l-e-m-o-m-s-s-e-n-c-o-m-e-i-n-m-o-m-s-s-e-n…”
This last sequence, hard and intense; the pipe went on vibrating long after it was over.
A pause. A dozen or so unintelligible taps, followed by a brisk series:
“R-e-c-e-p-t-i-o-n-w-e-a-k-r-e-c-e-p-t-i-o-n-w-e-a-k…”
Silence.
“C-o-m-e-i-n-p-r-a-t-t-c-o-m-e-i-n-p-r-a-t-t-o-v-e-r…”
Silence.
The pipe barely palpitated. The next series came at faint intervals, as though from far off: three dots, three dashes, three dots. SOS. There was a gradual tapering off. Two more dashes… one… then a long-drawn-out screeching noise, similar to a scraping or scratching against metal, amplified only by the aura of total silence.
He thrust himself away and swam headfirst along the pipe, veering where it veered, now climbing, now dipping, while the parting air brushed his face. An open shaft. A ramp. Narrowing walls. The cargo holds. Number one, number two, number three… He could barely see, it was so dark. He ran his fingertips along the pipe in order not to lose it, the brittle dust coating his hands charcoal-black, and found himself in another part of the ship, one not enclosed by any decks or ceilings, in the space between the armored hull and the holds. The bloated carcasses of the reserve tanks loomed up darkly between the crossframes, with only an occasional dust-speckled light beam knifing through the darkness. At one point he looked up and spotted a double row of lights in a black shaft, the bulbs encrusted with the same reddish-brown dust that kept trailing him like a cloud, like smoke from an undetected fire. The air was stuffy, stale, permeated with the smell of treated metal. He was sailing among the vaguely adumbrated shadows of the trusses when the clanking reverberations started up again:
“C-o-m-e-i-n-p-r-a-t-t-c-o-m-e-i-n…”
The pipe suddenly forked. He wrapped one hand around each of the forking
branches, but he failed to tell from which direction the sound was being transmitted. He gambled on the left. A hatch tunnel, pitch-dark, constricting to a bright disk at the other end, brought him out into a well-lighted room. The entrance to the reactor chamber.
“W-a-y-n-e-h-e-r-e-p-r-a-t-t-d-o-e-s-n-t-a-n-s-w-e-r…” the pipe went on resonating while he unbolted the door. A blast of hot air hit him flush in the face. He climbed up onto the catwalk. The compressors were humming away. A warm wind ruffled his hair. From the catwalk he saw, in foreshortened perspective, the reactor’s concrete wall, the luminous gauges, the warning lights shimmering like red drops.
“S-i-m-o-n-t-o-w-a-y-n-e-i-h-e-a-r-m-o-m-s-s-e-n-b-e-l-o-w-m-e…” the pipe reverberated, hammerlike, only a short distance away. At the point where it looped down out of the wall to join up with the main pipe inlet, standing with legs astride in front of the reactor shielding, was the robot; with quick jablike movements, as in some imaginary sparring match, he was applying cement filler by the fistful, slapping it around, smoothing it, molding it, before moving on to the next section. Pirx concentrated his ear on the rhythm of his movements, on the cadence produced by his pistonlike arms:
“M-o-m-s-s-e-n-c-u-t-o-f-f-p-r-a-t-t-l-o-s-i-n-g-o-x-y-g-e-n…”
Terminus stopped, with both arms uplifted, and poised opposite his deceptively human shadow. First to the left and then to the right he pivoted his box-shaped head in search of the next seam. He bent down, scooped up the sealant with his trowellike claws, and again the driving rhythm of his arms pulsated through the pipe:
“D-o-e-s-n-t-a-n-s-w-e-r-d-o-e-s-n-t-a-n-s-w-e-r…”
Pirx side-vaulted over the railing and floated down. “Terminus!” he yelled before his feet had even touched down.
