Mara's Prospect

The dock was manual. No guide rails, no automated grapple, just Caro on the approach thrusters lining the Paran up with a clamp that had been rebuilt at least twice from parts that didn’t match each other. The ship shuddered when the clamp engaged. Metal on metal, the sound traveling through the hull, and something in the dock structure groaned under the contact. Lev listened to the groan. Everything a station did was information. This one said the dock’s mounting frame was fatigued, which was probably true of every mounting frame on the station, which was probably something whoever maintained this station knew and had been living with for years, which was probably why they hadn’t wanted anyone here.

The seal pressurized. Green on the board. He checked it against the external pressure reading because green on the board was the dock’s opinion and he wanted his own. The numbers agreed. He trusted the numbers more than the board but less than he would have trusted them on a station whose maintenance history he knew.

Caro set the auto-transmit before they left the cockpit. Standard protocol: you walked onto a stranger’s station, you left a breadcrumb. The Paran would broadcast a status package to the network on a timer. Position, call data, last known conditions. If they didn’t reset it, it sent. The interval was usually twenty-four hours. Caro set it to twelve. He didn’t explain. Lev didn’t ask.

They suited up. Not full EVA. Emergency rigs, sealed, pressure-rated, two hours of independent atmosphere. You didn’t walk onto a station with pressure problems wearing your clothes. The rigs were bulky enough that Lev’s shoulder caught twice getting into his, which he noted and put in the same mental drawer as the biomarker check and the shoulder diagnostic and every other thing about his own body he was going to get to later.

Caro popped the inner lock, then the outer. The air that came through smelled wrong. Not dangerous wrong. Station-in-trouble wrong: the recycler bypass running lean, and underneath it the mineral smell of processed rock that was the station’s bones off-gassing things the primary system would have scrubbed and the bypass wasn’t bothering with. Every carved-out homestead had a rock smell. You usually didn’t notice it. When you noticed it, the atmospheric processing was working harder than it should be or not hard enough.

A woman was at the dock.

She was planted against the grip rail with one hand, the other hanging free in a way that looked relaxed and wasn’t. A man floated behind her. Bigger, younger, arms folded across his chest in a posture that gravity would have made aggressive and near-zero-g made effortful, because he had to brace against the wall to maintain it. He didn’t introduce himself.

“Koss,” she said. “You’re the Paran.”

She’d said we’ll have someone meet you at the lock and the someone was her. She was smaller than her voice had been on comms. Fifties, belt-built, the compact frame and dense joints of second-generation modification and a lifetime in low gravity.

“Harlan. This is Caro.”

Her eyes moved over them. The professional read, fast and automatic. The same assessment Lev was running on her, running on the man behind her, running on everything: the dock, the lighting, the sound of the air system, the temperature through his suit. Everyone sizing everyone up in the first three seconds, all of them pretending they weren’t.

“This way,” she said. “I’ll brief you on the way.”

She led them aft through a main corridor wide enough for two abreast and a cargo pallet, guide rails bolted along both walls at hip height. Past the dock gallery, past the junction nearest the hatch, deeper into the station. The route she’d chosen, the sequence she’d decided on. Systems first. People later. Founder-era construction: sealed rock faced with composite panels, bolted at intervals, the kind of work you did when you had time and materials and believed what you were building would last. Most of the strip lighting worked. A few sections were dim, and the dim ones had been dim for a while. The mounting brackets had that look.

“Atmospheric processing failed thirty-one hours ago,” Koss said. She moved through the corridor without looking back. She knew they’d keep up. “Primary recycler seized. Bearing failure cascaded into the catalytic bed. Breck had the bypass running in forty minutes, which is good, because the alternative was eighty-three people on whatever air was in the sealed sections and that’s maybe four hours.” She indicated the man behind them, who was following at a distance that said escort, not company. “The bypass is running about sixty percent of what we need. It’s holding. It’s not rated for the whole station, so we sealed the forward ring to reduce the volume we’re asking it to handle. That was step one. Step two was moving everyone aft. Step three was calling you, which I did after one and two because I wanted to tell you what we’d already done, not ask you what to do.”

“The forward ring is open,” Lev said.

Koss didn’t slow. “It wasn’t when I sent that message. Secondary seal failed eleven hours ago. We’d already moved everyone aft, which is why nobody was in it when the pressure cascaded through three compartments and the section went to vacuum. The section is open. The equipment in it, including Mirin’s bio lab, is gone. That’s where we are.”

Koss’s face did something when she said the bio lab. Brief. Controlled. Gone before Lev could read it.

“Anyone in it when it went?”

“No. We moved everyone when the primary seal failed.” The flatness in her voice was the flatness of someone who’d been giving this report to herself for eleven hours and had worn through whatever the first version of it had cost her.

The corridor opened into a junction where three passages met. People here. More than the space was built for. Families, equipment, the compression of a community that had retreated into its core and was fitting eighty-three people into the space designed for maybe sixty. Someone had painted the junction wall at some point, years ago. A mural, faded, showing the asteroid from the outside with the station’s lights on it like a constellation. A kid’s work, maybe, or a kid’s work improved by an adult’s hand. It was half-covered by a supply rack now but nobody had painted over it.

A woman was taping a conduit to the ceiling that had pulled loose from its bracket. Two men were running cable along the wall. A girl, maybe nine, was tethered to a handhold by a line clipped to her belt, holding a work light aimed wherever the cable crew pointed. She had the particular focus of a kid who’d been given a real job in a crisis and was going to do it until someone told her to stop. When the cable crew moved to the next section she re-angled the light before they asked, already reading where they’d need it. The cable man reached for a junction box and she’d already shifted the beam to illuminate the connector face, reading the routing pattern, predicting which branch he’d trace next. A nine-year-old tracking electrical topology through a station she’d lived in for her entire life. Lev filed it as belt kids grow up fast. Her free hand was tucked inside her jacket against the cold.

Lev’s eyes moved through the crowd the way they always did. The professional scan, automatic: build, coloring, carriage, how people held themselves in the zero-g. Belt stock, third generation mostly. The adults matched what he’d expect for a homestead population this age. The younger ones, the teenagers and kids, were lighter than his mental model wanted them to be. Not dramatically. Just enough that the number he’d have guessed for their bone density was a few points off from what he was seeing. He filed it. First impressions were unreliable, especially through a suit, especially in a station where everyone had been under stress for thirty-one hours. People looked wrong when they were scared.

Breck was still behind them. Lev was aware of him in the low-level way you tracked someone who hadn’t decided yet whether you were a problem or a solution.

A side corridor branched off to the right, toward what the schematic in his head said should be the lower habitation ring. Koss’s hand hesitated on the rail as they passed it. A half-second grip, maybe less. Her eyes didn’t move but her shoulders did, the faint pull of someone not looking at something. The lights were on. The pressure readout on the hatch frame showed equal atmospheres on both sides. Lev slowed. The corridor was wider than the one they were in, better maintained, and from where he held the rail he could see a second hatch at the far end, closed, with what looked like a keypad lock that didn’t match anything else he’d seen on the station.

Breck was in the gap before Lev caught the next handhold.

“Structural risk past that hatch,” Breck said. “Thermal stress on the framing.” His shoulders were square in the gap and his boots were braced against the frame and he wasn’t moving.

Lev held the look for a second. Then he pushed off and kept moving. Koss, ahead of them, hadn’t turned around. She didn’t need to.

Koss took the left passage. Narrower, newer. The composite panels gave way to bare sealed rock in patches, spray-on sealant that had yellowed with age, conduit runs that were functional and ugly. One section of corridor had been built differently from the rest, the panels thicker, the hatch frame reinforced. Lev read it as storm shelter, maybe. Founder-era caution. The temperature dropped as they moved. The forward ring was leaking cold into the adjacent sections, the rock conducting it, and the thermal management system was losing that fight at a rate Lev could feel through his suit.

“Sixty percent on the bypass,” Koss said, checking a readout on the corridor wall as they passed. “Enough for the aft sections if we keep the volume sealed and the population compressed. I’m planning on thirty-six hours before the filters need servicing, not the forty-eight Breck will tell you.”

“Because?”

“Because Breck is good at his job and optimistic about his equipment in roughly equal measure. I love the man but I plan around his optimism, not with it.”

Behind them, Breck said nothing.

They passed a compartment with the hatch propped open. Inside, someone working at a console surrounded by medical equipment in the kind of dense, organized arrangement you built over fifteen years in a space that was never big enough. She closed something on her console before looking up, a quick gesture, automatic, and then her eyes went to the portable diagnostic clipped to his belt, stayed there for a beat, then came back to his face. She went back to her console.

“Mirin,” Koss said, not slowing. “Medical.”

“I’ll need to talk to her.”

“After the briefing.”

It wasn’t a refusal. It was sequencing. Koss had a sequence, and the order she’d decided on was her briefing first, then the station’s problems, then whatever Lev wanted. He recognized it. The person in charge on site always had a sequence, and fighting that sequence in the first fifteen minutes was a reliable way to lose the next fifteen hours.

Operations was a compartment larger than the corridors, consoles on three walls, a central display showing the station schematic. The founder’s blueprint was there underneath, but what was on the screen was the blueprint plus decades of additions, modifications, expansions, patches. A station that had been designed once and then redesigned by everyone who’d lived in it since. Half the schematic was red. The forward ring and the three compromised compartments. The aft sections were green, except for two amber sections where something was holding but stressed.

Koss pulled herself to the main console and brought up the detail. “Here’s what we have.”

She walked them through it. The primary recycler: a unit rebuilt at least three times from whatever components were available, running to specifications that had drifted from the original because the manufacturer didn’t exist anymore and the specs had been adapted by whoever rebuilt it last, which was Breck, who’d done it well but well for this recycler meant well for the version of the recycler that existed after three rebuilds with non-original parts, which was not the machine the maintenance manual described. The manual described a machine that hadn’t existed in maybe twenty years. The intake bearing had failed. Lev’s hands remembered the bearing race on the platform, the housing that was out of true, the mount that had shifted. Different bearing, different station, same sentence. The seizure had cascaded into the catalytic bed, which was damaged in a way that couldn’t be fixed here.

“Bypass will hold,” Breck said. First words since the dock. His voice was aimed at the space between Lev and Koss. “I built it twelve years ago. Tested it every year. Serviced it on a schedule I keep in my head and on paper because the station’s digital logs corrupted twice in the last decade and I don’t trust them. It has never run as primary for more than four hours because the primary has never failed this badly, because I maintained the primary. The bypass is doing a job it wasn’t designed for and it’s doing it because I built it right.”

“For how long?” Lev said.

“Forty-eight hours on the filters before servicing. After that I clean them and we go again. You want to know what happens when the filters can’t be cleaned anymore, I’ll tell you: I’ll figure something out. That’s what I do here.”

Koss let him finish. She’d heard the speech before. It was Breck’s speech and he gave it when someone questioned his work, which was what Lev’s presence on the station implicitly did. She moved on.

The structural problem was the other front. The displaced habitation module they’d seen on approach. The mounting bolts had stressed when the rock shifted from thermal contraction after the forward ring lost its heat. A seal between the module and the rock face had cracked. Breck had patched it. The patch was holding.

“But the rock’s still cooling,” Lev said.

“The rock’s still cooling,” Koss confirmed. “The displacement is maybe two degrees off true. If the thermal profile keeps changing, it’ll keep shifting. If it shifts past what the patch can absorb, we lose that section.”

“And the section adjacent to it.”

“And the section adjacent to it.”

Two clocks. The bypass filters, thirty-six hours and counting. The structural patch, unknown. Both downstream of the forward ring breach, which was downstream of the primary recycler failure, which was downstream of a bearing that had been rebuilt from whatever was available because the original parts didn’t exist, which was the kind of causal chain that Lev had seen on fifty stations and would see on fifty more because this was how things failed in the belt: one component at a time, each failure revealing the next thing that had been holding on by slightly less than anyone thought.

“The filters I can service and extend your window,” Lev said. “Probably double the time if they’re not scored. The structural patch is the priority. If that seal goes before the thermal situation stabilizes, the volume math for the bypass stops working.”

Koss nodded. She’d run this calculation already. She’d run it hours ago.

“Caro.”

Caro had been at the edge of the compartment, reading the schematic slowly, completely, without asking anyone to explain what he was looking at. He’d grown up on a station like this one. The layout, the jury-rigged additions, the places where the construction changed quality because the materials had changed or the person doing the work had changed or the urgency had changed. Native fluency.

“The mount,” Caro said. He was looking at where the displaced module met the rock. “I need to see it. Welding kit. Whatever stock you have.”

“That’s my welding kit,” Breck said. Not loud. Just said. “My stock. My station. You’ve been aboard twenty minutes and you want my tools.”

“I want to fix your mount,” Caro said. Same flat tone. Not a challenge. A fact.

“I can fix my own mount.”

“You’re running the bypass,” Caro said. “You can’t be in two places.”

Breck looked at Koss. The residue of an argument that had ended before Lev and Caro docked. Breck had lost it. He knew it. Koss knew he knew it.

“Breck will take you,” Koss said. “Show him the stock, show him the mount, and then get back to the filters. That’s the sequence.”

“Fine,” Breck said. He pushed off toward the hatch.

Caro followed him out without a word.

Lev pulled the station schematic to his portable display and started marking. Bypass recycler, structural patch, sealed sections, population distribution. The amber zones on the schematic, where systems were stressed but holding. The locations of the emergency equipment Koss had mentioned, the sealed hatches, the pressure readouts he’d want to monitor. Eighty-three people in sixty percent of a station. The math was tight. Not crisis tight, not yet. The kind of tight where nothing was failing but nothing had room to fail, and if one element slipped the margins didn’t shrink, they disappeared.

He needed to talk to Mirin. He needed whatever she had on the population’s medication profiles, their modification baselines, their health history. If this went past thirty-six hours and people started showing stress responses, he needed to know which pharmaceuticals were safe for which bodies, and right now the only person with that information was the woman in the compartment they’d walked past, who had looked at him the way a clinician looks at a variable she hasn’t accounted for.

“The forward ring has equipment we need,” Koss said. She was watching him work. “Fabrication tools. Mirin’s bio lab. If the structural situation stabilizes, we’ll need to recover what we can.”

The bio lab. In the section that was open to vacuum.

“One thing at a time,” Lev said.

Koss looked at him. She didn’t say anything to that. She didn’t need to. The look was thirty-one hours of one-thing-at-a-time and the things kept adding up faster than she could get to them.

Lev checked the atmospheric readout on his portable. Pulled the bypass numbers, the temperature gradient, the pressure differentials across the sealed hatches. Oriented himself on the schematic. Found the route to Mirin’s compartment.

Two fronts. Caro was already gone.

He went to find Mirin.

Behind him, in the corridor outside operations, Breck was watching him go.
