“Murphy, wake up.” The soft female voice seemed distant.
He tried to roll and found himself restrained.
“Let us disconnect those,” she said.
He cracked an eyelid. The gray, curved interior of his hibernation chamber crowded him.
“What?” he croaked.
“There is a problem,” responded the voice. It represented the collective colony-ship Caretaker Programs.
“Why did I take this job?” he muttered.
“You are the Chief Mechanic,” she said.
He groaned. That wasn’t it. He’d wanted to prove himself. But to whom? His idiot engineer stepfather? His snooty, middle-management-drone ex? “It’s a long-term commitment,” they’d both warned with identical mock concern. As if he couldn’t think for himself. As if this was just another big mistake. Well to hell with them and everyone else that made it possible to feel lonely in the midst of twenty-billion people. He didn’t need them.
Here, he had purpose. He was Chief Mechanic. On Aberdeen Ceti Four he would be needed. He could start over without the muddle of uncertainties. He knew his job. No more mistakes. No more regrets.
Murphy flexed and released his muscles. They ached, but otherwise responded well. “How long did I sleep this time?”
“Seriously?” The mission was only 126 years old!
He cursed the company and its corner-cutting bean counters. Cheap bastards.
Soft pads released tender tissue and retreated into protective compartments. He punched the yellow easy-release panel. His tube hissed open.
“I envy you,” he said, stretching against post-suspension fatigue.
“You don’t tire.”
“All systems suffer entropy.”
“But you don’t feel it.”
“What broke this time?”
“Primary thruster one’s containment field is failing.”
Murphy shuffled to a console. The thruster reading was 42%.
Murphy toggled to the containment readings—15%. The ship trailed a wide path of radiation.
“What caused this?”
“The south receptor failed to operate to specifications. The field collapsed.”
“So switch to backup.”
“The present unit is the backup.”
“They both failed? Show the analysis.”
The numbers suggested a materials failure—a problem that could not be repaired en route. Murphy returned to the emission display. A huge radiation cone fanned from the thruster.
“Can we increase the others to compensate?”
New calculations appeared. “Not for the entire flight,” she said.
He studied the figures. They could handle the extra load for about 240 years. “Show dispersal if thruster one operated at 100% without containment.”
The cone brightened, but the acceleration kept the ship safely ahead of it.
“That looks okay,” he said.
“It is prohibited to use a containment-free thruster at that power level.”
Murphy rolled his eyes. “Containment regulations are for in-system flight … to protect nearby populations and intersecting ship routes.” You moron.
He examined the hypothetical thruster wear. Removing containment actually increased its longevity. Not that it was enough. At mid-journey the ship would pivot to decelerate, placing the entire payload—cargo, passengers and crew—smack in the middle of that lethal cone. He couldn’t use thruster one for deceleration, but the remaining thrusters alone would wear out before the end.
He considered waking the flight engineer. But an idea struck. “What can we get from thruster one if it only has to last another 360 years?”
The screen displayed an output range with corresponding probabilities of catastrophic failure at year 360—half way. Until then thruster one could operate at 160%.
“If we choose 160% for 360 years, and the remaining thrusters are conserved proportionately to maintain standard acceleration, what is the probability the surviving thrusters could handle deceleration to target, considering the reduced wear?”
The screen changed again. He smiled.
“Perfect,” he said. “Here’s the new plan: remove one’s containment entirely, take it up to 160%, and—”
Three quick tones sequenced the standard “error” signal. “Without containment, thruster one cannot exceed 30% of its standard operating output.”
“Sure it can. The radiation spreads away from the ship.”
“Those performance specifications cannot be attained. They are outside operational parameters.”
“No, they’re not. You’re enforcing a stupid safety rule. It’s got no application here. We’re deep in untraveled interstellar space. It doesn’t matter how much crap we leave in our wake.”
“We cannot exceed established parameters.”
“Safety override requires approval of a majority of administrators.”
Murphy folded his arms as the Caretaker Programs repeated the statement like a dimwitted child. He considered his options. The Caretaker Programs would follow rules unfailingly—into the heart of a supernova if that’s where it led.
“How many administrators are there?”
“There are currently 12 administrators.”
“And a majority of them would be …”
Crap. Murphy rubbed his neck. Despite a 19-year rest he felt exhausted, and the thought of waking six crewmembers to outvote a computer amplified his fatigue.
“You said currently?” he asked. “Has it changed?”
“There were four at startup.”
He strummed his fingers on the console. “Can I add or delete administrators?”
“How many can there be for a majority of one?”
“There can only be one administrator for a single administrator to be a majority of administrators.”
He tightened his jaw. I hope the Captain doesn’t review this log.
Murphy straightened. “Fine. Delete as administrators each of the following …” He touched the screen—one name at a time—except his.
“Done,” she said.
Murphy whistled softly. He was not a praying man, but he felt the urge now. If he keeled over with a stroke, the colony would be in sorry shape. What lame-brained designer thought it was okay to risk administrator abuse, but not okay to override inapplicable safety protocols? Of course, in Murphy’s experience, engineers and management shared one trait unfailingly: an appalling lack of common sense.
“If I die,” he whispered, not praying, per se, but the closest he’d come in many long years, “bring me back.” He drew a deep breath, and then raised his voice, addressing the Caretaker Programs. “Now, override safety protocol governing thruster power without a containment field.”
“Please specify limiting parameters.”
“No limiting parameters. Override every such protocol.”
“Bring thruster one to 160%; drop its containment entirely; lower thrusters two, three and four to 68%; maintain those levels until you start halfway procedures.” He cleared his throat and spoke with deliberate care. “Now listen carefully—before you turn the ship around, turn thruster one off! You got that? And shut it down permanently. It is not to be used during deceleration. Put the deceleration load entirely on thrusters two, three and four. Do you understand?”
He regretted his condescending tone. The Caretaker Programs were not idiots. They were state-of-the-art artificial intelligence. But they took things so literally.
“Now,” he said, relaxing. “Before I hibernate again, give me status of all major systems, and make me a snack.”
Most systems were well-within spec with only minor problems on the horizon. He walked the ship and visually inspected the pumps and actuators showing signs of premature fatigue. His best guess was that at least two of them would fail in the next 100 years. Everything else looked fine.
“Okay. Don’t wake me if you don’t have to. But no matter what, make sure we get there safely.”
“Please specify limiting parameters.”
He shook his head. He had already been over this. “No. You don’t understand. Are there any living things within twelve parsecs of our location?”
“—or within 12 parsecs of any point along our path?”
“Right. We’re in the middle of nowhere. Safety protocols that do not involve the safety of this ship and its crew and passengers don’t matter. They’re dangerous and unnecessary limitations. Override all of that.”
“That would include the Von Neumann subsystems.”
“That includes every system. This ship and its mission—that’s all you need to worry about. Get us there safe and sound. At all cost. Don’t cut corners. Okay?”
