Impact

The emergency klaxons had not started yet. That was the first wrong thing.

Caius was on his feet before his eyes opened, the soles of his bare feet registering the vibration through the deck plates a full second before his brain named it. A frequency too low for the drive signature and too high for a hull strike. It travelled through the metal like a tuning fork pressed to bone, and in the half-dark of the crew quarters it registered somewhere below conscious thought as a signal he had been trained to recognize and had hoped never to hear again.

Cascade failure.

He pulled on his pressure suit in twelve seconds. The zipper seal hissed home along his spine, a sound that in seven years of grounding had become muscle memory maintained by nothing except discipline. His hands did not shake. They never did. In the red half-light of the emergency strips that had finally flickered on—late, too late—he could see the fine tremor in the overhead conduits, the way the coolant lines were vibrating at a harmonic that meant the main structural spine was already compromised. Section isolation would be automatic at this stage, but the calculation ran through his head regardless: from this deck to the nearest escape pod bay, two pressure doors and one transverse corridor that would already be venting.

He had worked this problem before, in a different ship, with a different failure, and a different set of outcomes. He did not let himself finish the comparison.

The corridor outside his quarters was bending.

Not metaphorically. The port bulkhead had developed a visible curve, the alloy panels pulling inward where atmospheric pressure was dropping on the other side. A rivet shot past his ear and buried itself in the opposite wall. The air had a taste now—burned insulation, vaporized coolant, the metallic tang of structural metal under stresses it had never been rated for.

He moved. Protocol dictated the nearest escape station. The nearest escape station was three doors aft. He passed it without looking and headed for the engineering bay.

The sound of his own breathing in the helmet pickup was too loud. He switched off the intercom. The noises of a dying ship required no commentary.

The transverse corridor was worse. A section of ceiling had collapsed, and emergency foam sprayed from a ruptured seal in a hissing white cone that was already hardening into a frozen waterfall. He ducked under it. The lights along the floor strips blinked at half-interval—shipspeech for structural integrity below forty percent. A panel near his left shoulder peeled away with a shriek of tortured metal and vanished into the dark behind him. He did not look back. The pressure in his ears was dropping, and that meant the far end of the corridor was already open to vacuum, the air he breathed being pulled that way like water down a drain.

The door to the engineering bay was half-open.

The sight beyond it stopped him for a quarter of a second—a pause that in any other context would have been invisible, but which his own body registered as the first moment since the vibration woke him that his feet had stopped moving forward.

Through the doorframe, Caius could see stars. The outer hull had peeled back along the starboard seam, and the engineering bay was open to space. A junior tech—Dubois, first rotation, whom Caius had passed in the mess hall three hours ago holding a coffee bulb with both hands like a child holding something breakable—was drifting past the torn edge of the hull, already thirty meters out and rotating slowly, pressure suit intact but the helmet visor cracked in a starburst pattern that left no ambiguity about the pressures involved. There would be no recovery. There had not even been time to register the event.

And below the open sky, braced against the main control console with his back to the breach, was Voss.

Caius had not seen him in seven years. Not like this—not in the same room, not close enough to touch. He had tracked him in fleet personnel updates and twice at a distance across a docking bay on Aldrin Station, where the space between them had been measured in meters of deck plate and years of silence, and it had still not been enough. Now the distance was eight feet and closing, and Voss was on his knees with one hand—the fingers bent wrong, the knuckles open to bone—still working the reroute sequence on the console as though the engineering bay were not dying around him.

The darkness of Voss's hair had been one of the first details Caius noticed, seven years ago, under the harsh hangar lights of a test bay that no longer existed. Now it was matted with blood and coolant and clung to his forehead in wet strands, the grey at the temples—new since the last personnel photograph—glinting in the emergency strobe. His face was thinner than Caius remembered, the jaw sharper and the hollows beneath his cheekbones deeper, the architecture of a man who had been running on coffee and calculations for longer than was sustainable. His eyes, the same pale blue that had once spent six hours over a wiring schematic without blinking, were tracking Caius's features with the precision he had once reserved for engine diagnostics—an engineer evaluating an unknown variable. The blood loss had turned his skin the colour of ash, but the calculation in his expression was intact.

His abdomen was torn. A piece of hull plating, or perhaps a fragment of the console that had been beside Dubois when the breach happened—Caius did not see what had caused it, but he saw the result. A wound running diagonally from the lower ribcage to the hip, and the pressure bandage someone had slapped across it already dark and heavy. Voss's uniform was black where it should have been grey.

Caius reached him in three strides and seized his shoulder.

'Engineering bay is gone,' he said. His voice, through the helmet speaker, was flat. He had not spoken to this man in seven years and the first words were a damage report. 'Get up.'

Voss looked at him. The emergency lighting was failing in this section, strobing red-white-red-white at a frequency that turned every motion into a series of still frames. In the flashes, Caius watched Voss's eyes move from his face to his insignia—former insignia, the collar of a pressure suit did not carry rank—and then back to his face. A silent recalibration. The blood loss had greyed his skin, but the focus in his expression did not waver.

Voss did not speak. He did not ask why Caius was here. The question occupied the pause like a physical presence, a weight that pressed into the space between the strobe flashes.

Then the lower decks blew.

The sound was not a sound so much as a compression wave that travelled up through the deck plates and struck the soles of Caius's boots like a hammer. The lights went out entirely for a full second. When they returned, emergency-only, the ceiling had dropped six inches and the starboard bulkhead was no longer perpendicular to the floor.

Caius did not calculate the time remaining. He knew. Two waves of cascade failure had already propagated. The third would reach this compartment in less than thirty seconds.

He grabbed Voss by the back of his pressure suit and pulled.

Two hundred and ten pounds of dead weight against gravity already fluctuating as the ship's rotational systems failed. Voss's boots skidded on the deck. His right arm—the one with the broken hand—reached back toward the console, toward the panel beside Dubois, toward the open sky and the drifting shape growing smaller. The fingers could not close. The gesture was pure instinct, a reflex written into muscle before the brain caught up to the damage, and it made Caius's grip tighten in a way that had nothing to do with the ship coming apart.

'The junior tech is dead,' Caius said. His voice remained level. The helmet speaker stripped everything from it except information. 'He was dead before you hit the deck. Move.'

Voss's head turned. His eyes found Caius's through the visor. The expression in them was unreadable in the strobing light, but the arm came back down.

They made the emergency bulkhead as the engineering bay ceased to exist.

The blast door dropped with a hydraulic slam that Caius heard through his bones rather than his ears. Two seconds later, the pressure on the other side equalized with the vacuum and the door bowed inward by a quarter inch before the emergency seals locked and held. The compartment behind it—the main engineering bay where the ship's heart had been beating thirty seconds ago—was now an open cavity in the hull, and whatever had been in it had become part of the debris field expanding outward in the ship's wake.

The corridor ahead was still pressurized. That was the extent of the good news. The escape pod bay lay thirty meters down a passageway that had not yet collapsed, and Caius covered the distance with Voss's arm across his shoulders and Voss's blood soaking through the shoulder of his suit, warm where everything else was turning cold.

There should have been three pods.

The readout on the launch bay wall ticked the inventory in cold amber characters: Pod A—launched. Pod B—launched. Pod C—standby. The launch computer had already locked the selection, and the number on the door was 1. Single occupancy. The pods in this bay had been retrofitted for survey missions, stripped of the standard two-man configuration to make room for sample storage and environmental buffers. The one remaining pod was designed for exactly one occupant, and the ship's emergency systems had stopped asking questions when the first hull breach was detected. It would launch. It would not ask whether it launched one person or two.

Caius opened the hatch. The pod's interior was thirty inches wide and fifty-eight inches deep, a padded acceleration couch occupying most of the volume. He pushed Voss in first and there was no gentleness in the motion, only necessity—Voss's body hit the couch at an angle that made him hiss through his teeth, the first sound Caius had heard him produce since entering the engineering bay.

Then Caius was inside and the hatch was closing and the launch computer was counting down from three and there was no room to secure the harness for either of them because the pod was built for one and Caius had one arm pinned between Voss's back and the bulkhead and the other braced against the overhead and Voss's face was inches from his and the count reached zero.

The launch was a fist driven through the pod from below. The acceleration crushed Caius against Voss, who gasped—a wet sound that the thrust noise nearly buried—and then the main drive cut and the secondary thrusters fired and the pod spun, realigning, the starfield outside the single porthole rotating in a sickening arc before the stabilizers caught and locked and the universe stopped moving.

Silence.

The kind of silence that follows an explosion and means you have survived it, which is not the same thing as being safe.

The pod's emergency lights came on. Red. A steady red, not the strobing chaos of the dying ship, but a flooding crimson that painted everything inside the pod the same colour: the acceleration couch, the instrument panel, the two men crushed into thirty inches of space. Caius's hands. Voss's face. The blood still seeping from beneath the pressure bandage, threading down the curve of Voss's abdomen and pooling in the shallow depression where Caius's hip pressed against his thigh. All of it red.

Caius could not move. Not immediately. The launch had jammed him into the angle between Voss and the port bulkhead, one leg trapped under the acceleration couch's support strut, his chest against Voss's shoulder. The reading light on the instrument panel flickered amber-green-amber—the diagnostic cycle completing its automated sequence, the computer cataloguing damage that neither of them required a machine to confirm.

Their breathing filled the pod. Two sets of lungs in a space designed for one. Voss's inhalations were shorter than Caius's, and each one ended with a catch—the sound of a man who had learned in the last ten minutes exactly where the boundary of his own body now lay. The air already tasted of something used. Re-breathed. The CO2 scrubbers were rated for one occupant, and that rating was based on assumptions that no longer applied.

Caius extracted his leg from under the strut and shifted his weight sideways. The movement brought his knee against the medical kit bolted to the lower bulkhead, and he reached for it automatically—an acquisition of a tool whose purpose he had already calculated—then stopped. The wound needed attention, but the wound was under a pressure bandage that was still holding, barely, and the first priority was knowing whether the pod would keep them alive long enough for a wound to matter.

He pulled up the diagnostic panel.

The display was small, amber characters against black backing, the interface designed for a pilot who would be reading it under worse conditions than these. Caius was a pilot—had been a pilot, the distinction was administrative and he did not let himself make it—and the data organized itself in his vision the way flight data always did: immediately, completely, the picture assembling before the individual numbers had finished registering.

Three microfractures. Port quarter, forty-seven degrees. Starboard forward, one-forty. Dorsal aft, two-seventy-eight. The pattern told him the pod had not launched clean—something had struck the hull during the ejection sequence, probably debris from the disintegrating survey vessel, and the alloy had developed hairline cracks at three stress points. The computer flagged each one with a time-to-failure estimate: twenty-six hours, nineteen hours, thirty-one hours. At any given moment, the pod's skin was bleeding atmosphere through fractures too fine to seal with emergency foam but large enough to matter when every cubic foot of oxygen was a non-renewable resource.

Atmosphere at eighty-seven percent of nominal and declining at one-point-two percent per hour. That rate was calculated for one occupant. With two, the curve steepened. Caius ran the mental arithmetic—four hours, perhaps five before the CO2 concentration crossed the threshold where cognitive function began to degrade—and then he did not let himself follow the calculation further because there was only one conclusion and it was not useful.

Beacon: online, frequency nominal, signal strength forty-one percent. The power cells were leaking, likely the same debris strike that had caused the fractures, and the beacon was drawing more current than the emergency cells were rated to sustain. It would broadcast. For a while.

Trajectory: the pod was travelling at ejection velocity plus a drift component, and the drift component angled away from the last known position of the rescue corridor. The computer rendered it as a vector on the navigation display, a thin amber line arcing through a wireframe starfield that was wrong in a way Caius did not need the computer to quantify. The rescue corridor was a twenty-kilometer-wide cylinder of space that patrol ships maintained as an emergency lane for survey vessels operating in this sector. The pod should have launched into that corridor. It had not. And the drift was carrying it further out with every minute.

He had been reading the panel for perhaps forty seconds when Voss spoke.

'What's the O2 gauge reading.'

Not a question. A flat statement with the rising inflection of interrogation worn away—the way Voss had always spoken when he was too exhausted or too focused to bother with the social machinery of inquiry. His voice was hoarse, the words catching on something raw in his throat.

The sound travelled down Caius's spine and settled at the base of his skull. He knew that cadence. He had heard it across a workbench in the test bay hangar, seven years ago, Voss's voice reading pressure tolerances from a clipboard while Caius ran the pre-flight ignition sequence at quarter power—a conversation about fuel mixture ratios that had been, in retrospect, the last time they had spoken as something other than strangers who shared a duty roster. The hangar had smelled of machine oil and ozone. Voss's fingers had brushed his when he handed over a torque wrench, a contact accidental enough to ignore and deliberate enough that neither of them had acknowledged it. Caius had held that wrench for a long time after Voss walked away. He had still been holding it when he found the flaw in the ignition sequence—the one that would have detonated the test vehicle on the pad, the one that Voss's team had missed, the one that Caius had buried by sabotaging his own career before the launch could proceed.

He had not thought about the wrench in seven years. He was thinking about it now because Voss's voice had not changed and the pod was the same size as a cockpit and the red light made it impossible to see whether Voss was looking at him or at the O2 gauge or at the same memory neither of them would name.

'Eighty-seven percent,' Caius said. 'Declining at one-point-two per hour, single-occupant baseline. Double that for two.'

His eyes stayed on the panel. Reading the next line of data as if it were the next item on a checklist. His hands were steady on the diagnostic controls. The red light made it impossible to tell whether the blood on his gloves was fresh or had been there since the launch.

'Single occupancy rated at eight hours nominal,' Voss said. He was studying the same numbers, or the blank bulkhead above them—Caius could not see his face without turning, and he did not turn. 'With the fracture bleed, four hours usable. That is a generous estimate.'

The words arrived in a measured rhythm, the cadence of an engineer reading specifications aloud while another part of his brain processed the implications. Except the rhythm was wrong. There were pauses between the words where there should not have been pauses, gaps where Voss's body was informing him that speaking required abdominal muscles and his abdominal muscles had been bisected by a fragment of the ship he had been trying to save.

Caius said nothing. He was reviewing the beacon diagnostics now, or the power allocation table—the distinction was irrelevant. What mattered was that he was not looking at Voss, and he continued to not look at Voss while he read, and the silence stretched into a shape that was different from the seven-year silence that had preceded it but was still a silence, still populated by all the things neither of them had spoken aloud.

The pod was twenty-nine inches wide at the shoulders and eighteen at the footwell. Their bodies occupied ninety percent of the available volume. Voss's hip was against Caius's thigh, and the contact point was warm where the blood had soaked through both their suits. Every breath either of them took changed the pressure in the pod in a way the other could register. The microfractures were bleeding air into space at a rate the CO2 scrubbers could not outrun, and the beacon was transmitting a signal that would not reach the rescue corridor for another hour at minimum, and the rescue corridor was moving in a different direction than the pod, and all of this was true and none of it was the thing that kept Caius's eyes on the instrument panel instead of the man sharing his air.

Voss's hands lay across his abdomen just above the wound, the wrists bent at an angle dictated by the swelling of broken fingers, the palms facing inward as though cupping something invisible. The right hand was worse—two metacarpals visibly fractured, the knuckles already dark with bruising that had spread in the minutes since the engineering bay, the fingers crooked at joints that would not straighten. Caius had seen field injuries before. He knew what hands looked like when someone had shielded something with them—a face, a control panel, another person—and the force had exceeded what bone could absorb.

Dubois had been standing at the auxiliary station when the hull breached. That was the direction the debris would have come from—the angle that had forced Voss to reach across his own body with his dominant hand, the hand that should have been on the console, and shield—

Caius did not complete the reconstruction. The image finished itself.

He reached for the medical kit. The latch released under his thumb with a click that was startlingly loud in the confined space, and the kit unfolded in his lap, revealing rows of vacuum-sealed packages arranged with the obsessive economy of emergency medical supplies. The inventory sorted itself: one suture pack, sealed, expiry date stamped in red—eighteen months past manufacture. Half a roll of sterile tape. Two ampoules of local anaesthetic, and when he held one up to the panel light the liquid inside had separated into two distinct layers, a stratification that meant the chemical compounds had degraded past the point of reliability. One pressure bandage, the same model as the one already failing across Voss's abdomen. One pair of field scissors. Three antiseptic wipes. Gauze pads.

He did not need the manual to understand that the suture pack had been intended for lacerations, not abdominal wounds that had penetrated muscle wall. He also did not need the manual to understand that the alternative to using it was watching Voss bleed out over the next four hours while the oxygen dwindled and the pod drifted further from the rescue corridor.

It would take about thirty minutes to suture. Perhaps forty, given the working conditions—the red light, the cramped quarters, the fact that the patient was a man whose ribs Caius could count against his own chest with every breath. The expired anaesthetic might provide fifteen minutes of numbness if it functioned at all. The remainder of the procedure would be unmediated.

And Voss would not be able to do it himself. His fingers could not hold the needle. The swelling had progressed even in the minutes since the launch, the broken metacarpals pressing against the skin in contours that made Caius's own hands register the absence of the damage they had not sustained.

He set the suture pack on the edge of the instrument panel where Voss could see it.

Voss looked at the pack. Then at Caius. The red light had deepened the hollows under his cheekbones and shifted the pale blue of his irises toward grey, but the precision in his gaze had not changed. He was still doing the math—the same arithmetic Caius had done, subtract the time from the air, divide the pain by the anaesthetic, carry the remainder.

Neither of them spoke.

The pod's environmental monitor issued a soft chirp. In any other context it would have been a notification. Here it was a countdown.

Caius's hands remained steady on the suture pack. The red light painted them the colour of something that had already happened and could not be reversed. Outside the porthole, the stars that had wheeled too fast during the launch were now silent and still, and the survey vessel was no longer among them, and the rescue corridor was a line on a display receding at three hundred meters per second.

The pod had thirty inches of space. Most of it was occupied by two men who had not spoken in seven years. The rest was occupied by a question that neither of them had asked, and the oxygen it took to continue not asking it.
