Orbital Decay: Drop Trajectory

The training blade struck the grating panel with a flat, percussive crack that echoed off the curved walls of the Harvester's aft cargo bay. Maren watched the impact point where the polymer edge had kissed the steel, leaving a thin white groove, and waited for Yara to come around.

"Again. Slower on the second axis. You're compensating with your core, not your hips."

Yara banked mid-tumble, her boots magnetized to the opposite wall so only her torso floated free. She reoriented, one hand pressing flat against the grating for a half-second pivot, then released. The blade in her right hand described a lazy arc through the recycled air, trailing a faint ozone scent that clung to the bay's thin atmosphere.

"Compensating is efficient," Yara said. Her voice came out flat, transactional, as if she were reading a damage report. "You call it leverage. I call it not getting my neck snapped."

Maren floated lower, her knees bent, fingertips trailing along the safety line that tethered her to the floor grid. "Aye, and a snapped neck don't file reports. Let me call the next set." She checked the chronometer clipped to her forearm. "We've got three rotation cycles left before I want you on the full sequence. You ken the protocol. Twist, stabilize, twist the other way. No drift."

"I know the protocol."

"Then do it."

Yara released the wall. Her body hung free in the grey half-light of the bay, the overhead strips calibrated to simulate low-visibility engagement. The blade swung clear. She initiated the first rotation: shoulder lead, core engagement, hips following like a hinge catching wind. The second twist came clean. Then the third, and the fourth, and by the seventh rotation her movements had developed the mechanical smoothness of a gyroscope finding its axis.

Maren counted silently. Eight. Nine. Ten.

On the eleventh rotation, Yara's rhythm broke. Not a stumble. Not a miscalculation. Her fingers whitened on the blade's grip, and her gaze dropped to the floor, as though she could see something there that lived only in peripheral vision. The blade wobbled. The next twist was shallow, off-axis, her body tilting two degrees too far toward port.

"Hold," Maren said. Not a command. A hand on the stillness.

Yara froze mid-drift, the blade hanging still, its tip pointing at nothing. For three seconds she didn't move. Then her stomach convulsed, a visible spasm that rippled down from her throat to her lower ribs, and she brought the flat of her palm to her mouth.

"Yara." Maren unclipped the safety line, pushed off the grating, and closed the distance in two floating strides. "Easy. Breathe."

"I'm fine."

"You're not fine. You've got the green. I can see it up in your gills."

Yara's jaw worked. She turned, pressing her forehead against the cold steel of the bay wall, and the sound that came out of her was not human. It was a short, ragged wet noise, like a pipe bursting behind a bulkhead. Then the second wave hit, and she retched onto the floor grating, her boots sliding, the magnetic soles releasing with a sharp clank.

Maren caught her. One arm under Yara's shoulders, the other gripping the training blade in Yara's still-clenched hand and yanking it free, the polymer edge clattering against the grating. She held Yara steady, her palm pressed flat between the station commander's shoulder blades, feeling the shudder run through the other woman's frame like a signal fault.

"Let go of the wall. Come here." Maren guided her to the center of the bay, away from the grating, away from the puddle of bile that was spreading in thin, iridescent sheets across the metal. The smell was acid and copper, sharp enough to sting the back of the throat. Maren unclipped a fluid sachet from her belt and pressed it into Yara's hands. "Sip. Don't swallow fast."

Yara took the sachet. Her fingers were steady. That was the worst part. Everything else had gone to pieces in the last four seconds, but her hands moved with the same mechanical precision as the rotation exercise, squeezing the pouch in one controlled motion, the warm saline trickling between her lips.

When the shivering stopped, Yara floated in a slow, involuntary roll, the safety line Maren had clipped to her harness keeping her from drifting to the ceiling. Her hair, short and ink-black, floated in a rigid halo. Her face was grey in the strip-light, the veins at her temples standing out like dark roots under soil.

"Flagged," Yara said.

Maren tilted her head. The word hung in the thin air between them, small and blunt as a spent cartridge.

"Ideological review. Fleet Compliance, Division Nine. The flag came through on cycle three of the transit. Buried under the resupply manifest." Yara's voice had the flat, clinical quality of a briefing to a new officer. No inflection. No request. "They want a statement. Forty-eight hours. They want me to explain why I ordered the evacuation of Outpost Six without full damage assessment."

Maren stopped floating. She braced one foot against the grating, planting herself, and looked at Yara the way she looked at a hull breach: measuring the extent, calculating the patch, deciding how much structural tolerance remained.

"Outpost Six," Maren repeated. Her accent surfaced in the vowels, softening the ends. "Aye. You lost the comms array. You pulled your people off the rock before the thermal cascade. That was right, woman. That was the only right call."

"The review doesn't care if it was the right call. It cares if I followed the escalation matrix."

"The escalation matrix don't have a clause for 'the rock is cooking and your people are in the line of fire.' You made a decision under duress. I don't ken why that's a crime."

Yara's eyes were open, fixed on a point above Maren's left shoulder. Her gaze tracked nothing. "They cite my second command failure. The Kethani relief. Three hundred and twelve personnel lost when I held position for six hours instead of withdrawing."

Maren's jaw tightened. She knew the Kethani file. Every officer on Helios-7 knew it. Three hundred and twelve names, printed on the memorial wall in the station's central atrium, each one a small brass plate that someone had to keep clean or the whole registry would be downgraded. She had helped polish them, every new transit cycle, because that was what you did when you were family to the dead.

"You don't get to do that," Maren said. Her voice was quiet. Warm, but with an undercurrent that reminded Yara of a blade held flat against the throat. "You don't get to stand in a cargo bay on a ship called the Harvester, floating in zero-g with your stomach in your boots, and you don't get to pull Kethani out of that file like it's a weapon pointed at your chest."

"I'm telling you the situation."

"You're telling yourself a story. And the story says you're guilty before the review even starts. Which is convenient, aye? Because if you're guilty in your own head, then the flag is just paperwork. You already served the sentence."

Yara's mouth opened. Closed. The fluid sachet in her hand crinkled, the last warm drops of saline beading on the seal.

"Shut up, Voss."

"Ken that's not what I said."

"It's what you meant. You're the family one. You took your brothers off the rubble when their parents' habitat went. You've been doing the 'I'll carry it so you don't have to' routine for a decade, and now you're doing it to me in a cargo bay on a goddamn corvette." Her voice cracked on the last word, just a hairline fracture, a single syllable of exhaustion that slipped through the armor. She caught it immediately. Patted her mouth with the back of her hand. "I'm going to sleep in the medical bay. Twenty minutes. Then I'll file the statement myself."

"You're not filing a statement from a cargo bay floor with bile on your boots." Maren released the safety line and floated a half-meter closer. Her hand went to Yara's wrist, pressing two fingers to the pulse point. Sixty-two. Low. Too low. "You're going to lie down. You're going to drink something that isn't a combat ration. And you're going to let me draft the statement so it reads like you actually know what you're doing, instead of like a woman who's been waiting for permission to be found out."

Yara pulled her wrist free. "I'll draft it."

"You'll draft it after you've slept. I'll have the file pulled by then. I want to see every line they intend to hold against you before you put a word down."

"They can hold whatever they want."

"Aye, well. They can. And you can stand in front of Division Nine and say 'hold whatever you want' in that flat, briefing voice, and they'll file it under 'commander lacks self-correction capability.' Which is the exact thing the flag is designed to trigger." Maren crossed her arms, floating two inches off the grating, her boots trailing. "You don't owe them a performance, Yara. But you owe yourself a clean file. Because the next time a rock cooks and you've got people in the line of fire, I want you to be free to pull them off without looking over your shoulder for a compliance officer."

The silence that followed was not empty. It was the silence of two women who had been orbiting the same problem for eleven days, circling each other in the cargo bay like moths around a cold light, each one convinced the other would say the thing that would finally make the circling stop.

Yara's eyes found Maren's. Held them. The grey in her face was fading, replaced by the usual pallor of a woman who had not slept more than four hours in three days. Her expression was a flat, level landscape. No peaks. No valleys. Just the vast, dry expanse of a commander who had decided, in that moment, what she would show and what she would not.

"Twenty minutes," Yara said. "Not more. And you don't tell Ines."

"Ines has known about the Kethani file since we left Helios-7. She's been polishing her brass plates and waiting for you to stop pretending they're just decoration." Maren released Yara's wrist, turned, and pushed off the grating toward the medical bay's corridor. Her boots clanked against the hull plating, each step a small, percussive mark in the quiet. "I'll have the file on the comm unit in the med bay. Twenty minutes. Then you eat. Then we work."

Yara floated in the center of the bay, one hand still gripping the crumpled fluid sachet, the other pressing flat against the cold steel wall for purchase. She could feel the metal's chill through her palm, a thin, clean cold that cut through the lingering nausea like a blade through fog. The bile on the grating was beginning to smell differently now. Not acid. Not copper. Just stale, slow, and wrong, a biological sourness that the recycler hadn't caught because the sensors in the aft bay were calibrated for cargo, not vomit.

She released the wall. Let herself drift. The blade lay on the grating where Maren had dropped it, its polymer edge catching the low overhead light in a thin white line.

Twenty minutes.

Yara closed her eyes, and the dark behind her lids was not empty. It was full of three hundred and twelve names, each one turning slowly in the zero-g, each one a small brass plate that someone had to keep clean. And beneath the names, the flag. Division Nine. The forty-eight-hour clock ticking down in a room she would not be allowed to enter until she had filed a statement explaining why a commander had saved two hundred and four people by breaking the protocol that was supposed to ensure all three hundred and twelve survived.

She opened her eyes. The bay was still. The strips overhead hummed at a frequency just below hearing, a low, steady vibration in the floor plating that she felt through her boots more than heard with her ears.

Somewhere ahead, down the corridor, Maren's boots were still clanking against the hull. Steady. Measured. The sound of a woman who had decided, eleven days into the transit, that she would not let the woman in the cargo bay fall.

Yara pushed off the wall and began the slow, rolling drift toward the med bay. Twenty minutes. She would keep the time. She would eat what was offered. She would not say another word about Kethani.

And when the file was on the comm unit, she would read every line. She would not sign anything until Maren had looked over it and told her, in that warm, measured voice that had lived in the low vowels since the habitat collapse, that the words held. That they were not a confession dressed in a protocol matrix.

The Harvester carried on through the dark. Eleven days out, and the transit would not shorten itself. But the cargo bay, for now, held only the smell of stale bile and the hum of the overhead strips, and the slow, patient clank of boots on steel, and the quiet understanding that some distances could not be covered in a straight line.

The corridor narrowed where the med bay junction met the transit spine, a two-meter constriction of curved plating and conduit runs, and Maren Voss stopped at the edge of it. Her boots found their final groove in the steel. The clanking ceased. In the sudden quiet, Yara could hear the hum of the recycler cycling overhead, a flat, tireless drone that she had stopped noticing on day three and now noticed again because Maren had been the only variable that broke the pattern.

Maren filled the narrowing. Not all at once. She came in slowly, one hand flat against the wall for momentum in the low gravity, her face catching the strip-light in a way that made the planes of it look carved rather than grown. The kind of face you studied while you were trying not to think about it. The kind of face that had lived through a habitat collapse and decided, against every protocol, that it would keep making tea for other people's children.

"You don't have to eat the protein block if it makes you sick," Maren said. Her voice carried that low, rolling quality, the vowels stretched long and warm, like words pulled slowly through a loom. "I'll flag the mess cycle. We can do broth instead."

Yara did not take the protein block. She had been drifting with it in her left hand for four minutes, the foil wrapper crinkled and damp with her sweat. "I'm not sick."

"Your pulse is one-twelve and climbing. I saw it on the med bay readout from the junction panel. You don't need my permission to be sick, Yara."

The name landed without title. Without rank. Maren said it the way she said the names of the station's systems, as though it were a designation, a label on a console panel. Yara. Maren. Ines. Tobias. Bram. Five names in a sequence that had become, over eleven days, something that was not quite friendship but was not quite duty either. A holding pattern.

Yara held the protein block up and let the foil crumple further under her thumb. The recycled air between them tasted of nothing, the way air on Helios-7 always did: clean, slightly metallic, stripped of every scent that might have made a person feel like they were still on a world with soil and rain. "I'm going to eat it."

"You are going to eat it."

"Yes." She swallowed the block dry, no water, the compressed texture scraping the back of her throat. She watched Maren's jaw work silently. The engineer's expression had shifted, that measured, patient look she got when she was deciding whether a correction was necessary.

It was not necessary. Maren let it go.

They stood in the constriction for another twenty seconds. The strip-light above them ticked, a microsecond of flicker that made both their shadows jump against the plating. Yara noticed the way Maren's hand rested against the wall, fingers splayed, the pad of her thumb pressing into a seam in the metal. A small, unconscious thing. The kind of gesture that said I am holding onto something.

Then Yara's hand was already moving.

Not fast. Not the way a commander reached for a comm unit or a sidearm. Slower. The left hand, the one that had been cradling the protein block, rotated. The block fell away, tumbling in the low gravity, and what was in her palm instead was smaller than she expected. Smaller than it had been when she'd pulled it from the fold of her flight jacket two hours ago, back in the cargo bay, while Maren was still clanking down the corridor and the bile smell had been so thick she'd thought the Harvester itself was sick.

A shard of ceramic.

Not a chip. Not a fragment broken off in some accident. It was shaped, or had been shaped, by hands. A wedge roughly the size of a thumbnail, one edge flat and smooth, the opposite edge fractured and raw, showing the white core beneath a thin coat of dark glaze. The glaze was blue-black, the color of a sky that had not yet decided it was night. There was a hairline crack running through the center, not a break, just a line, like a river seen from very far above.

Yara's palm opened. The shard sat in the center of it, and in the strip-light it looked less like a piece of broken pottery and more like a splinter of the ground. Of the Earth's ground. The specific, unrepeatable ground where a kiln had sat in a workshop in a town whose name Yara could still say in her sleep, in the two minutes before the dreams started and the dreams became something else entirely.

"Take it," Yara said.

Maren looked at the shard. Then at Yara's face. The measured warmth in her expression did not waver, but her mouth tightened, a small, controlled line. "Yara."

"My sister." The words came out flat, clipped, the way Yara issued orders. But the flatness was wrong. It was a wall she was building in real time, brick by brick, and Maren could see the scaffolding. "On Earth. The girl in Kethani's district. She's nineteen now. She's in a care facility because her legs did not recover from the secondary shockwave, and the state allocation is, and was, insufficient. I stopped the allocation three years ago when I took command. I told her I was redeploying funds. She believed me for two years. She stopped believing me when the letters stopped coming back with responses."

Maren's hand lifted from the wall. It hovered, uncertain, in the low gravity between them. Not reaching yet. Waiting. The way Maren did everything: waiting for the correct moment, for the correct angle, for the thing to be ready before she set it down.

"If I do not come back from this deployment," Yara said, and her voice had gone thin, the cold precision stripped away to something raw and unformatted, "if the drop trajectory fails, if the station loses structural integrity during the re-entry window, if any of the things that I have filed in the safety matrix happen and I am not in it, you take her."

A beat. The recycler hummed. Somewhere behind them, deep in the Harvester's belly, a pipe exhaled a long, shuddering sigh of steam.

"You take the shard to the workshop on the east side of the district. The one with the green door. You press it into the ceramic glaze on the kiln shelf, in the gap between the second and third row. That is the cipher. That is how she knows it is me. Or it is you. Or it is no one, and she is alone in the facility, and the state allocation is still insufficient, and the letters still stop." Yara's jaw worked. She did not blink. "The shard is not a message. It is a hand. She will know a hand by the fracture line. My mother broke that bowl the night the habitat went. She pressed the pieces into the glaze while the kiln was still warm and said, this is what we keep. This is what carries the shape forward. The shard is the shape, Maren. It is the only proof that was here, that is here, that will be here if I am not."

Maren's hand was in the air now. Fully open. The low gravity made it look slow, weightless, a gesture suspended. Her fingers were not quite at the shard yet. There was a gap, three centimeters of empty, recycled, metallic-smelling air between them, and in that gap Yara could see the whole eleven days compressed. The protein blocks eaten in silence. The comm files read and unread. The way Maren had stood at the junction panel watching the readout while Yara pretended not to notice. The way Maren had made tea, actual tea, not the instant variety, for Tobias and Ines on day seven because she had found a packet in her kit and the smell of it had made the transit corridor feel, for four minutes, like a kitchen. Like a place where the floor was solid and the sky was a color other than the grey of a hull interior.

The shard crossed the gap.

Maren closed her fingers around it. The ceramic was cold, colder than it should have been, colder than the ship's ambient temperature allowed, and Yara felt the transfer as a small withdrawal, a subtraction from her own mass. Her palm was empty in a way that was not just physical. The blue-black glaze caught the strip-light one final time as it slid between Maren's thumb and index finger, and the fracture line was visible even at this distance, that thin river through the center, that line that was not a break.

Maren did not say anything for four seconds. When she spoke, her voice had dropped, the Scots lilt pulling the vowels deeper, the warmth turning to something more private, more guarded. "I will not let her be alone in that facility."

"You don't have to."

"Yara." Maren's gaze held. The measured, patient look, but harder now. The kind of look that had looked at a habitat collapse and decided, against every protocol, that children did not die in the dark. "I am not doing this as a favor. I am not doing this as a protocol. I am doing it because you are the only person on this station who made me understand that a command failure is not the same as a person. And you are asking me to hold a shape. A small, chipped, blue shape that means I was here. I kept this. I did not let it melt back into the glaze. " She shifted the shard in her fingers, turning it so the fracture line caught the light. "I will not let it melt back."

Yara exhaled. The air in the constriction was warm, Maren's warmth, and the recycled nothingness, and the faint, chemical tang of the protein block she had just swallowed. She pressed the back of her hand against her mouth, a small, mechanical gesture, the way a pilot checked her oxygen seal. When she lowered it, her eyes were dry. They had been dry since the cargo bay, since the bile, since the first eleven days of refusing to sign the file.

"If the drop fails," Yara said, and the words were flat again, the wall rebuilt, the bricks set, "you will need a statement. For the girl. For the facility. For the state. You will need to say that Commander Tench, in the event of structural loss during re-entry, designated Chief Engineer Voss as the custodian of a personal asset. A ceramic artifact. Valued at zero credits. Class: irreplaceable."

Maren's mouth moved. Not a smile. Something adjacent to a smile, the ghost of one, the way the green door on the workshop would have looked if you passed it at night and only caught the edge of its color in the streetlight. "I will file it under personal effects. Next to my mother's thimble."

"Your mother's thimble is in the med bay drawer. I saw you put it there on day four."

"I am aware of where my thimble is, Commander."

Yara laughed. It was a small sound, a click, like a ceramic piece settling into a shelf. Not a real laugh. The kind you made when the wall had a crack in it and you were not sure if the other side was air or void. The shard, in Maren's palm, caught the light one more time as the engineer's fingers closed around it, the blue-black glaze going dark, the fracture line vanishing under skin.

The protein block hit the floor of the constriction. It rolled, once, in the low gravity, and came to rest against Maren's boot. Neither of them picked it up.

Maren turned. Her hand, with the shard pressed flat against her palm, disappeared into the inner pocket of her work jacket. The fabric of the pocket bulged, slightly, a small irregularity in the line of her silhouette. She walked on, the clank of her boots resuming, steady, measured, the sound of a woman who had decided, eleven days into the transit, that she would not let the shape melt back into the glaze.

Yara stood in the constriction for another thirty seconds. The recycler hummed. The strip-light ticked. Her empty hand was still open, the palm up, the lines of the skin pale and unmarked, and she held it that way, the way you hold a bowl after the last piece of food has gone into it, the way you hold the ground after the kiln has cooled and the shape is either preserved or it is not.

The Harvester carried on through the dark. The transit did not shorten itself. But in the pocket of the chief engineer's jacket, three meters down the corridor, a shard of blue-black ceramic rested against the fabric, cold, and raw at the fracture edge, and shaped, and holding the shape of a night in a workshop where a woman had broken a bowl and said, this is what we keep.

And the girl in Kethani's district, nineteen years old, lying in a care facility on a planet that had not yet heard the name Helios-7, turned over in her sleep and did not know that the letters would stop coming, and that a small, chipped, blue shape was crossing the void in the pocket of a woman who made actual tea, and who would press it into the glaze on a kiln shelf with a green door, in the gap between the second and third row, and that the gap would be filled, and that the shape would carry, or it would not, and that either way the kiln would still be warm when the hands were steady enough to set it down.

Yara closed her palm. The constriction narrowed. The corridor went on.

The targeting packets were spread across Maren's work surface in three columns, their datapad screens casting a flat blue-white light across the dark of the systems bay. She had been at this for forty minutes. Forty minutes of running the drop vectors for the Kethani district insertion against the orbital approach corridor, checking clearance margins, verifying the thermal signatures of the descent plumes against the station's radiative shielding. The work was quiet, mechanical, the kind that lived in her forearms and the inside of her teeth. The recycler breathed behind her. The bay hummed at a frequency she could feel in the fillings of her back molars.

She rotated the primary ingress packet one degree counterclockwise on the holo-projector, aligning the vector line with the Arcadia Planitia survey overlay. The corridor for the civilian refugee transit ran in a pale amber thread along the survey grid, threading north-northeast through the Planitia's southern trough. Maren had seen it three times already. She saw it a fourth time and her thumb stopped moving on the scroll pad.

The amber thread was not beside the ingress vector. It was not parallel to it, not adjacent, not even close. It ran directly beneath. The two corridors nested, one stacked on the other with a vertical separation of perhaps two hundred meters at the nadir point, and at the nadir the gap narrowed to ninety. Ninety meters of regolith and fractured basalt between a squad of combat descent and a column of civilians who had not yet left the ground.

Maren pulled the packet back. Re-ran the survey overlay. The amber thread held its course. She pulled the ingress vector back. It held too. She set both on the projector side by side and leaned in until her breath fogged the glass of the holo-unit. The geometry was clean. The overlap was exact. Not a drift, not a rounding error, not the kind of tolerance variance you saw when a survey team was working in dust storms and their lidar bounced off a sandstorm and came back smeared. This was clean. This was plotted. Someone had taken the refugee corridor and walked it under the drop corridor with the patience of a man drawing a line through the center of a drawn circle.

She set the datapad down. The blue light fell across her knuckles, and she looked at them for a moment, the way you look at your hands when they have just done something you are not sure you meant to do. The light was steady. Her hands were steady. The station hummed.

The door slid open without the soft hydraulic whisper of a controlled entry. It simply parted, the seal breaking with a small metallic tick, and Yara Tench stood in the frame. She had not knocked. She did not knock. The corridor light behind her was a thin white line, and she was wearing the same grey transit jacket, and her expression was the expression of a woman who had been walking a long time and was not finished.

"You are not in the transit log," Yara said. Not a question.

Maren's thumb found the scroll pad. "I am in the systems bay. I am running the Kethani vectors."

"You have been in the systems bay for fifty-three minutes."

"I have."

Yara crossed the floor in four strides. The soles of her boots made no sound on the metal grating; she walked like the floor owed her the silence. She stopped at the projector, looked at the two corridors, and the thin white line of corridor light behind her caught the edge of her jaw, making it a hard angle.

She did not speak for six seconds. The recycler cycled. The hum shifted a half-tone as the station's attitude thrusters fired a micro-correction. Maren felt the vibration travel up through the grating, through the soles of her own boots, into the architecture of her knees.

"Ninety meters at the nadir," Yara said. Her voice was flat, informational, the tone you used for a weather report. "Is that a survey variance or is that a planning choice."

Maren rotated the ingress packet three degrees. The amber thread slid under the blue vector line and the overlap became visible from a second angle, more obvious, less forgiving. "I ran the clearance model four times. Four times, Commander. The variance is zero point two meters. That is not a survey variance. That is not a rounding error. Someone took the refugee transit and walked it under our drop corridor on purpose." She paused. The word sat in the air between them, small and heavy, the way a stone sits in the palm of your hand before you decide to throw it or not. "This is engineered."

Yara's jaw worked. Not a grimace. A mechanism. The kind of movement that meant she was doing arithmetic at the back of her skull, running the number of bodies in the refugee column against the number of bodies in the descent squad against the number of bodies in the two hundred meters of regolith that separated them. She did this fast. She always did this fast. Maren could almost hear the gears, the little metallic clicking behind the flatness of her voice.

"Who plotted the refugee corridor," Yara said.

"The transit authority for the Planitia survey. They filed it eleven days ago." Maren pulled up the metadata. Her finger traced the filing stamp on the pad. "Eleven days ago. That is three days before we got the descent order."

"Three days." Yara's voice dropped one register. The word landed in the bay like a small, cold object set on the work surface. "They knew the drop window before the Fleet did. They knew it and they built the corridor to sit under it."

Maren looked at her. The blue light of the projector made Yara's skin look grey, and the thin line of corridor light behind her had narrowed to a sliver, the angle of the station shifting as it turned on its long axis. "You are not thinking what I am thinking."

Yara did not answer for a moment. She reached out and touched the holo-projector with one finger, and the gesture was so small, so quiet, it was almost tender. The two corridors held in the blue air, amber and blue, nested, waiting. "I am thinking," she said, "that if I file a deviation order to reroute the descent vector, I am admitting that the plan on the table is a plan that kills a refugee column. And if I do not file it, I am the one who drops onto it."

The recycler cycled again. The hum found its frequency. Maren's hand was still on the scroll pad, her thumb resting on the glass, and she felt the vibration of the station through the pad, through the pad through her thumb, a small, persistent pulse, like a second heartbeat that was not her own.

"So what do you file," Maren said. Her voice came out softer than she intended. The Scots rounding, the low consonants, the way she swallowed the edges of words instead of sharpening them. "You are the commander. You file what you file."

Yara looked at her. The grey light caught the hard angle of her cheekbone. "I file the deviation. I reroute the descent three kilometers east. I buy the column ninety meters of margin and I log the anomaly and I do not think about what it means that someone had our drop window three days before the Fleet did." She turned her hand away from the projector. The corridors stayed, floating in the blue, patient. "But I do not file it until you tell me the east corridor is clean."

Maren pulled the east vector from the stack. Her fingers moved fast now, the mechanical focus reasserting itself, the kind of concentration that lived in the hands and not the head. The east corridor was a wide, open trough, no amber thread, no nested geometry. Clean. She ran the thermal signature. Clear. She ran the clearance model. Clear. She set the packet on the projector beside the others and the three vectors hung in the blue air, and the east one was empty, and the safe one, and the one that did not nest under a column of people who had not yet heard the name Helios-7.

"East is clean," Maren said.

Yara nodded once. A single, sharp movement. "Then we file it. I will sign the deviation in six minutes. You draft the routing correction for the descent team and you flag the anomaly for Fleet intelligence. You use the clean channel, not the open net. If this was plotted to be found, I do not want it found by the people who plotted it."

Maren opened the routing template. Her cursor hovered over the first field. The blue light was steady. The station hummed. Somewhere three floors down, the recycler was doing its quiet, endless work, pushing the same air around the same pipes, not knowing that the air it was pushing was about to be routed around a column of civilians who were about to be told to walk three kilometers east and pretend the ground beneath their feet had not been measured for the purpose of killing them.

She typed the first line of the routing correction. The characters appeared on the pad, small and blue and final.

"Commander," she said, without looking up. The cursor blinked. "If this was engineered for collision, the person who engineered it is still on the Planitia. Still in the transit authority. Still feeding data to the corridor model."

Yara's hand, the one that had touched the projector, was flat on the work surface now, the palm down, the fingers spread. The lines of the skin were pale. "Then we do not call them out. We do not flag the transit authority. We reroute, we file the anomaly under a generic survey variance, and we let them keep feeding data into a corridor that no one is using anymore." The flatness of it. The weather-report flatness. "We let them plot their collision with a ghost."

Maren looked up. The blue light caught her eyes and held them, and for a moment the two of them sat in the small, humming bay with the corridors floating between them, amber and blue, nested, and the girl in Kethani's district still sleeping on a planet that had not yet heard the name Helios-7, and the small chipped blue shape in Maren's jacket pocket, cold against the fabric, shaped like the night a woman had broken a bowl and decided, against all sense, to keep the pieces.

"Understood," Maren said. She turned back to the pad. Her thumb found the scroll. The routing correction filled, line by line, each one a small, clean decision, a small, clean choice to move the drop three kilometers east, to buy the column its ninety meters, to let the engineered collision sit in the dark of the Planitia's southern trough with no one above it, no one to meet it, no one to land on it. The cursor blinked at the end of the last line. The station hummed. The recycler breathed.

Yara was at the door. Her hand was on the seal. The thin line of corridor light had widened to a full blade, catching the edge of her shoulder, the hard geometry of her collarbone. She did not turn. "You file it before I do. You flag the anomaly on the clean channel. And Maren."

"Yes."

"The bowl." Yara's voice came from the threshold, small and clipped, the way she said things that were not meant to be heard by anyone but the person standing three meters away. "I will put it on the shelf. Gap between the second and third row. The green door is still warm." She pushed the seal. The door slid. The corridor light stayed, a thin white line in the frame, and then it was gone, and the bay was dark, and the blue light of the three datapads was all that filled the room, all that held the shape of the work, the work of moving three kilometers east, the work of letting a collision happen to nothing.
