A Taste of Copper
Liora
The first sign that our air was failing was the taste of a clean spoon.
I was eating peaches over the sampling bench, trying not to drip syrup into a sensor worth more than my berth. The spoon touched my tongue. Copper. I set it down and licked the inside of my lower lip. The taste stayed.
Across the compartment, Mara Vale waited with a freight receipt in her hand.
I had wanted to kiss her for a year. This was inconvenient enough without having to decide whether the room was poisoning us.
“Don’t sign that yet,” I said.
She glanced at the receipt. “I was hoping you’d read it first.”
“I mean don’t touch anything. Give me a moment.”
Mara became still. She was good at that. Pilots who survived long enough to complain about their knees knew when an instruction needed a question and when it needed a body that didn’t move.
I slid my peaches away from the inlet, wiped my fingers, and took a second sample. The handheld analyzer needed time to settle. People tended to look at its first number and panic or celebrate according to temperament. I watched the line beneath the number, the one showing how rapidly conditions were changing.
It was going the wrong way.
Our maintenance tender, Bluefin, was halfway through a perfectly ordinary watch in a perfectly ordinary piece of the Saturn lanes. We had supplies, a booked service slot, and three spare scrubber cartridges in the cage aft. We were not near the gate exclusion boundary. Nothing exotic was supposed to happen here. On a ship, that left plenty of ordinary ways to die.
“Mara. Does the flight deck smell different?”
“Like Oren reheated his boots for dinner.” She stopped when I didn’t smile. “Warm. Sharper than it should. I thought the galley had burned something.”
“Any headache?”
“Not until I saw your face.”
I looked at her properly. Gray flight suit, sleeves fastened at the wrist, dark scarf tucked into the collar. Her short brown hair lay flat on one side where she’d slept against a headrest. A tiny amber light on her left hearing aid blinked as she adjusted its setting. She was tired. We all were. Fatigue made a useful hiding place for symptoms.
“I’m checking the scrubber,” I said. “Call Oren. Ask for live environmental readings, not the summary.”
She was already at the wall panel.
I opened the inspection flap beneath my bench. Condensation had gathered along a pipe, each bead swollen and trembling with the ship’s vibration. The return air should have been warm enough to keep that surface dry. I touched the housing with the back of my glove. Heat on one side. Cold on the other.
A technician could build a whole career out of discovering that a machine was doing two contradictory things at once. It didn’t make the discovery pleasant.
Oren’s voice came through the speaker. “Environmental summary is green.”
“Actual numbers,” Mara said. “Liora’s got a bad sample.”
“It’s not a bad sample. It’s a bad result.”
She corrected herself immediately. “Bad result. Send the feed.”
I appreciated that more than I wanted to. A little accuracy, handed back without a performance. She had done the same thing on our last contract, caught herself calling an alarm a nuisance and changed the word before I could object. I’d remembered it for months. Apparently I had a romantic weakness for people who could survive being corrected.
The feed appeared on my pad. Oxygen within operating range. Carbon dioxide rising, not yet at the level that would set off the old general alarm. Fan draw elevated. Heater temperature cycling sharply instead of holding steady.
Enough to investigate immediately. Not enough to tell eight people their last hour had arrived. I had no intention of inventing that hour.
“Stop recirculation from the aft lab,” I told Oren. “Keep forward supply running. Notify Tavi and wake everyone who’s asleep. I want people checked, not frightened into running.”
“You have authority to isolate the lab?”
“Under the environmental fault procedure, yes. Log my name.”
He took one breath. “Logging.”
Mara stood just outside my light, the receipt still folded between two fingers. She’d shifted a work lamp so its beam no longer reflected in my gold safety glasses. I hadn’t asked. I hadn’t even realized I was squinting until the glare was gone.
“Where do you need me?” she asked.
The answer that rose first was too large for the question. I wanted her at breakfast. In a room where neither of us was about to depart. On the other side of a table I didn’t have to pack away after a meal.
“Supply cage. Don’t open the cartridges. Bring the case here.”
“I can do that.”
She tucked the receipt into her suit pocket and went.
I pressed my palm against the bench until the attraction settled into something I could work around. There were moments when the body seemed badly designed for survival: thirst at the wrong time, trembling fingers, the remembered warmth of a woman whose sleeve had brushed mine eleven months earlier. I didn’t need to stop feeling any of it. I needed to keep it from deciding which valve I touched.
The scrubber unit sat behind a mesh screen two compartments aft. I took my analyzer, notebook, and breathing mask. The mask was an emergency bridge device with a small independent supply. It would give me a way through a bad corridor, not a private atmosphere for an entire repair shift.
Tavi met me at the first hatch, pulling their coverall over a thermal shirt. They had a pencil behind one ear and a crease from their pillow across their cheek.
“How wrong?” they asked.
“Rising carbon dioxide. Uneven heater cycle. I don’t know the cause.”
“Good. I hate it when you know before you wake me. Makes me feel replaceable.”
They checked their own mask indicator before checking mine. We did it in that order every time, so neither person would be tempted to skip a step while watching the other. I nodded toward the panel.
“Lab return isolated?”
“Confirmed mechanically. Oren sent the command. I checked the indicator at the damper.”
That was two forms of confirmation, not two proofs that everything else would work. We moved through the hatch.
The air tasted worse near the unit. Heat had baked dust into the smell of old toast. A thin white crust marked the drain connection. I photographed it before touching anything, with the unit number visible in the same frame. Tavi opened the service cover and held it while I inspected the heater contacts.
One was discolored. The adjacent insulation had gone stiff and brown at the edge.
“Not a software reset,” they said.
“Not yet any kind of reset.”
The ship’s screen lit with an incoming depot call. Manager Rusk had received the fault notification faster than I expected. His face appeared above the service diagrams, washed out by whatever overhead light he worked beneath. He was on a depot, breathing air that wasn’t our air, looking at the same green summary Oren had trusted.
“Liora. I see the ticket.”
“Then you see the request for replacement authorization.”
“I see a transient reading. The shipment was certified. Cycle the unit and sample again.”
“There’s physical heat damage at the contact.”
“Did it stop working?”
Tavi looked at me across the open housing. I could almost hear the answer they wanted to give: everything works until it doesn’t. I kept my voice flat.
“The output isn’t holding within trend. We’re isolating affected compartments and testing the replacement batch. We also need a support vessel advised.”
“A support call means route disruption.”
“Yes.”
The word hung between us. There were useful arguments I could have made about costs and repair hours. I didn’t make them. If the price of admitting a fault was inconvenience, inconvenience had to be allowed to exist.
Rusk rubbed one eye. “I can release technical support. No need to describe it as a distress situation until you have a confirmed failure.”
“I’ll describe what the instruments and inspection show.”
“I don’t want an unqualified warning on an open channel.”
“Neither do I.”
Tavi lowered the cover onto its catches. I watched their hands rather than Rusk’s face. A person could talk endlessly about procedure while someone beside them did the work that made procedure possible.
When the call ended, I sent Oren a measured advisory: environmental fault, eight people aboard, temporary isolation established, replacement testing underway, assistance requested before margins narrowed. No claim that we were already out of oxygen. No permission for someone else to wait until we were.
Oren acknowledged the message in writing. I kept the acknowledgment.
Back in the forward passage, Bex was pouring water into cups. She ran our galley and knew, better than any briefing I could give, how many tired people forgot to drink when something frightened them. Senn sat on the deck with his back against a locker, gray around the mouth.
“He says he’s just tired,” Bex told me.
“I am just tired,” Senn said.
I crouched beside him. “Then you can be tired in the forward refuge. How’s your head?”
“A bit stupid.”
“That’s not a measurement I can put on a form.”
“Aching.”
“Better.”
He tried to stand too quickly. I put a hand on his shoulder and asked him to wait while Bex brought a portable monitor. He was an adult trainee, old enough to resent being treated as cargo and young enough to hide a symptom because he’d been given a job worth keeping. I recognized the instinct. It was one of the things I disliked most about our profession.
“We’re checking everybody,” I said. “Reporting a headache won’t get you removed from the crew.”
“Getting dramatic about it might.”
“Not on a report I write.”
He looked at me then, properly, and told me his eyes had been hurting too.
I noted the time, asked Bex to stay with him, and gave Oren the update. Symptoms and rising readings together changed the urgency. The old alarm could keep its threshold. We didn’t have to keep its judgment.
Mara came down the passage carrying the supply case against her hip. She stopped when she saw Senn.
“Is he all right?”
“He’s being checked. Take that straight to the bench. Then I need the flight deck’s current attitude and the next support approach window.”
“Already requested.”
She didn’t tell me not to worry. It was one of the reasons I’d wanted her long before I had any right to need her.
At the bench, she put the case down gently enough that the metal feet made almost no sound. It held three cartridges, each wrapped and sealed in a rigid tube. The shipment label was still under its clear cover, corners intact. Official certification followed the lot number.
I ran a finger over the cover and looked up at Mara.
“You brought these on your last supply run.”
“Yes.”
“Any temperature excursion? Cargo bay leak? Anything that seemed too small to put in the handover?”
She considered the questions individually. I watched her do it, resisting the ugly wish that she could answer with the speed of innocence. A careful memory took longer than a defense.
“One outer crate had a damp corner. The inner case looked dry. Depot said it was condensation from transfer. I noted the crate and they gave me a replacement sleeve.”
“Did anybody open the inner case?”
“Not in front of me.”
I wrote that down exactly. The distinction would matter. She’d seen a damp crate. She hadn’t seen damage to its contents. Those were different facts even if they eventually led to the same place.
The shared bench light made the old burn on her right wrist visible where the sleeve had ridden up. I’d asked about it on our first contract. She’d said a kettle, a bad morning, and nothing heroic. I’d liked the refusal to improve the story. Now I needed her to keep refusing, even if an improved story would make it easier for me to look at her.
“Your handover receipt,” I said. “Can I see the whole thing?”
She took it out and laid it flat.
Not just her signature. Depot release time, packaging note, destination, and a second page where somebody had entered final testing. I checked the date and frowned. It wasn’t a contradiction I could interpret yet. I marked it for later rather than drag an accusation out of a timestamp while the air kept changing.
Mara watched my pencil move.
“Tell me if I missed something,” she said.
“I will. First we need to know what we’ve got.”
I gave the cartridge tubes names in my notebook: A, B, C. A was closest to the hinge, B in the center, C by the latch. After that, nobody would be allowed to refer to one as the other spare. Three was a small inventory. It could still become a fatal confusion if we moved things without keeping their names.
Mara checked the analyzer while I broke the outer seal on A. Our shoulders were close. I could have leaned a fraction and rested against her, taken one second of heat from a living person instead of another reading from a box.
I didn’t. Not because I thought wanting her was wrong. Because I had never learned how to ask for something before I could offer a guarantee in return.
The seal split with a small dry snap. I lifted the lid.
The packaging beneath it should have rustled. Instead, it clung.
I tilted the tube toward the light. A transparent bead gathered along the inner edge and rolled onto my glove. Not sweat, not humidity from the room: the inside of the sealed cartridge had held enough moisture to soak its paper sleeve.
Mara moved the light closer.
Neither of us spoke while I checked the lot number against the case.
The replacement in my hands was wet.
The Spare That Wasn’t
Liora
I put cartridge A into a clean tray before I allowed myself an opinion.
The tray had separate compartments. I fixed A’s label to the left one before transferring any loose media, then asked Mara to photograph the arrangement from above. A loose strip of packaging could otherwise end up beside the wrong sample when we opened B. She included my handwritten identifier in the picture and checked that it was readable. We were not preserving a courtroom exhibit perfectly. We were keeping ordinary handling from destroying information we might need to understand the failure. I wrote the sampling time beside the image number.
Mara stepped back so I could work. She hadn’t made excuses for the damp crate. I tried not to count that as generosity. It was the minimum I needed from a colleague, even a colleague whose thumb I could feel in my memory without ever having held her hand.
“Tavi. I need you forward,” I said into the wall panel. “Bring the test block and a second witness.”
“What kind of witness?”
“One who can say whether a sleeve is wet without having to keep the shipment on schedule.”
“I’ll bring Bex. She has no respect for schedules.”
Mara looked at the tray. “Does moisture automatically ruin it?”
“No. It changes what I have to verify.”
That was the honest answer. Sorbent media could tolerate particular conditions within defined limits. Water inside a sealed replacement, combined with a batch that had traveled through a questionable crate, put it outside the assumptions printed on its label. I couldn’t give the label authority over what lay beneath it.
I weighed a sample, recorded the value, and checked the granules against the reference material. Mara read the scale aloud while I wrote. We swapped tasks on the second measurement. If my hands had begun to shake, I wanted another pair of eyes watching the numbers rather than politely ignoring them.
Tavi arrived with Bex and the test equipment. The cook wore her insulated galley apron over a sweater, as though she could turn any room into a kitchen by arriving properly dressed.
“Please tell me we’re not eating that,” she said.
“Not unless everything else goes very wrong.”
“Excellent. I draw the line at chalk.”
She signed the observation line in my notebook and stayed to watch the second cartridge open.
B looked dry until I tipped it over the sampling mesh. The outer granules separated into powder. A pale cloud rose and I closed the lid at once, turning my head away. Tavi switched on local extraction. We waited for it to clear before I moved again.
Mara reached toward my shoulder and stopped short.
“Are you breathing all right?”
“Yes. Keep back until the filter finishes.”
We checked exposure and surfaces before testing anything else. There would be no satisfaction in identifying a bad cartridge by swallowing it.
The second sample performed worse than A. It had been dried after damage, perhaps, or made from media whose history we didn’t yet know. I wrote down the behavior rather than the theory. Wet A. Crumbling B. Two separate tubes, separate retained samples. The labels looked identical, which was why the labels would remain with their contents.
C opened without moisture or visible disintegration. I still didn’t declare it safe. We tested the actual output under controlled flow and watched the temperature response. Tavi checked the rig for leaks while Bex read the unit identifier into the record.
Only after the performance settled did I let out the breath I’d been holding.
“One usable spare,” I said.
Mara leaned both hands on the far side of the bench. For the first time since I’d tasted the spoon, she looked openly frightened.
“We brought three.”
“We brought three containers. We can use one.”
Bex folded the corner of her apron between two fingers, then smoothed it flat. “Can one keep us alive?”
“Not if we keep treating the whole ship.”
It was the answer I’d been building toward since the first trend line. Hearing it spoken made the room feel larger, an extravagant volume of air we’d have to stop using. The empty aft lab didn’t care whether it remained breathable. The workshop didn’t need fresh oxygen to preserve a rack of spare brackets. People did.
We could seal unused sections, establish a smaller refuge, and run a temporary scrubber with C. It required power, controlled airflow, and people willing to stay where we could measure them. It would buy us time to repair or transfer, not erase the need for help.
Before anybody moved, I named the next task for each person and asked them to repeat it. Mara would handle the approach, Bex the people and supplies, Tavi the portable assembly. The plan sounded less frightening when its actions belonged to particular hands.
Bex asked about the galley heater.
“Off until we know the load,” I said.
“The main heater, yes. I have a small independent warming plate. Different circuit.”
“Bring it forward unplugged. We may need its parts.”
“Do we get to eat first?”
“Cold food. I’m sorry.”
She studied me. “You didn’t manufacture the cartridge. Stop apologizing for the temperature of a cracker.”
Then she went to pack food for eight people.
Rusk called while we installed C into the portable unit. Tavi was torquing a connection and couldn’t spare a hand for the panel, so Mara answered. The manager asked for me as though she were an unsuitable receptionist rather than the person who had flown his supplies across the lanes.
“Liora’s handling the replacement,” she said. “You can speak. We’re logging the call.”
His mouth tightened. “The batch certification is current.”
“The media failed testing,” I said, without looking up from the seal. “I’ll send the results and photographs. Two cartridges aren’t usable.”
“Your local rig isn’t the depot rig.”
“No. That’s why I retained samples. You can compare them later.”
Tavi held up a pressure check. I nodded, waited for it to stabilize, and gave them permission to continue. Rusk had to wait through the same silence as everyone else.
“You’re restricting habitable volume on the basis of an improvised test?”
“On the basis of a rising environmental trend, physical damage to the main unit, two failed spares, and symptoms in a crew member. Would you like those as separate lines?”
Mara looked down so quickly that I suspected a smile. I didn’t turn to confirm. I had a seal to inspect and no spare attention for being pleased with myself.
Rusk said he would send a revised operating schedule. I asked him to send the original test records instead. He promised both, which wasn’t the same as providing either.
After the call, Mara sent the approach request again, this time on the local service channel as well as the depot system. She described our position precisely and stated that the vessel remained maneuverable within limited power. A ship whose air failed could still fire its engines. That did not mean it could spend its battery without considering the heater keeping the sorbent active.
The portable unit began its steady low draw. I checked the exhaust, then the inlet, then the compartment’s changing readings. We weren’t fixed. The direction had improved.
Tavi put their pencil against my notebook.
“Say it,” they told me.
“Temporary control established.”
“Good. I was worried you’d try to say congratulations.”
I almost laughed. The air didn’t hurt my mouth anymore, but I wasn’t ready to trust the absence of taste. Symptoms were messengers, not instruments. They could leave before the room became safe.
Oren announced that Jules and Adra had sealed the aft lab. Bex was moving food. Senn, after rest and a check, could help carry soft supplies but would remain out of the bad return passage. Tavi would take the portable unit forward on its cart. Mara and I would sweep the workshop and verify the final closures.
I asked each person to repeat their location and task. Oren sighed at the repetition until I told him to count the voices. Eight. He stopped sighing.
On the way aft, Mara handed me an emergency mask.
“I’ve got one.”
“That’s Senn’s spare. I need you to check the indicator. Mine looks odd beside it.”
It wasn’t an excuse. Her own gauge sat slightly off the reference mark. We compared them under the same light and rejected her cylinder from immediate use until Tavi could inspect the valve. Mara exchanged it for a checked unit from the locker.
If she had wanted me to think her invulnerable, she had chosen an unpromising demonstration. Instead she clipped the replacement to her belt and let me see that being competent included finding a fault in your own equipment.
The workshop was warm and unoccupied. A sheet of printed flimsy fluttered beside the fan grille, held by one corner under a bolt. I pulled it free and found our old cleaning roster on the back. Mara used to write messages on those rosters during our first assignment, little sketches of spectacularly ugly ships. I’d kept one for reasons I had never admitted to another adult.
“You remember this compartment?” she asked.
“Different tender. Same bad storage brackets.”
“I meant the work.”
“I remember the work.”
She looked at me, then turned away to close a cabinet. I’d answered the safest part of the question again. It was a skill I needed to stop practicing if I ever wanted a different result.
We checked lockers for sleeping crew, maintenance spaces for people who might have heard only part of the announcement, and the washroom for a broken flow warning that could waste our reserve water. There was no stowaway, no uncounted passenger to spring from a cupboard. Only things we had to bring and things we had to leave.
My small case was still beneath the bench. It contained a sweater, a book with a loose spine, and the contract offer I’d printed because reading it on a screen made it feel too easy to delete. Departure in ten days after this assignment. Independent atmosphere work, better rates, no reason to keep booking ships where I might see Mara.
I took the case.
She watched without asking what was in it. I resented her for being careful, then resented myself for wanting her to know things I refused to tell her. It was possible that my worst habit wasn’t silence. It was hoping someone else would prove their love by overcoming it.
Love was too big a word for a passage full of bad air. I kept it to myself and checked the last cabinet.
At the aft hatch, we donned our masks for the transfer. I could hear my own breath moving through the small supply system, each inhalation close and private. Mara checked the seal around my jaw without touching my skin, using the inspection tabs. I checked hers. We gave each other a visible thumbs-up and crossed.
The forward refuge held six waiting people and the portable scrubber. Bex had arranged food on a folded blanket instead of a table, preserving clear access to the panel. Oren had brought the communication set. Jules sat cross-legged with an inventory of patch material. Adra had a medical kit open beside Senn, who was trying to help without pretending he felt fully well.
Tavi watched the flow meter as though it were a particularly unreliable pet.
Mara closed the final hatch. I checked the seal indicator and, after pressure settled, verified the isolation at the local panel. Only then did we remove the masks.
The refuge air smelled of bodies, adhesive, and a packet of Bex’s dried herbs that had split in transit. It was not pleasant. It was measurable and improving.
I counted everyone by name, aloud. Tavi answered with a raised pencil. Senn said present as if we’d returned to school. Bex told him school had better snacks.
Mara sat beside the communication set and worked the service bands. Static broke in and out as local interference crossed our path. We weren’t cut off from civilization. We had unreliable access to it, which was frustrating in a different, very practical way. Oren adjusted the antenna alignment while Mara repeated the advisory.
The reply arrived in pieces.
Service tug Sparrow. Captain Imani. Received our position. Working an approach outside a debris transit corridor. Required us to conserve power and prepare a safe docking orientation. They could not simply ram a rescue sleeve through an obstruction because we wished them closer.
Mara asked for a repetition of the approach condition. Imani gave it. Oren wrote down what they actually said, leaving a gap where a word had been lost instead of completing the sentence from hope.
When Mara looked up, every person in the refuge was watching her.
“Help knows where we are,” she said. “They have a real route problem. They’re working it. We’re going to do the part we can do here.”
She didn’t promise an arrival time she hadn’t been given. I wanted to put my hand over hers. Instead I offered her a cup of water and sat beside her long enough to make the wanting harder.
The heater indicator flickered. I leaned forward at once, then stopped. A brief control cycle, within the pattern we’d just measured. My shoulders had climbed toward my ears. Mara noticed and shifted her knee slightly, close enough that I could feel the heat without touching.
“You can watch it from here,” she said. “You don’t have to stand over every number.”
“I know.”
“Do you?”
I looked at her. We were not talking about a number anymore. I could hear the question she didn’t press: whether I ever let anyone remain beside me when I wasn’t useful.
“I can try,” I said.
Mara leaned back against the wall. It was the smallest invitation I’d ever failed to misunderstand.
Across from us, Jules finished laying out the blankets. People shifted to make room for an elbow, a boot, a frightened young man who didn’t want to say he was frightened. We were crowded, competent, and already tired.
There was enough room for all of us. The air was another question.
