The transition from the relative warmth of Silas Thorne’s workshop back into the cold, unpressurized docking bays of Maeve’s Outpost was like stepping into a freezer with a throat full of sand. Mark Kelly held the single, heavy Hydrazine Fuel Cell against his chest with his right arm, his raw, blistered palm stinging through his suit liner. His left hand, clumsy and stiffened by the severe frostbite on his thumb, cradled the custom-machined manual thruster bypass key. Every breath he took was a shallow, guarded effort; the metallic taste of toxic ammonia from his previous repairs on the station’s water-recycling unit lingered on his tongue, a grim reminder of his permanent lung damage.

"You look like hell, Kelly," a gravelly, resonant voice barked over the local suit channel.

Mark turned his head inside his helmet, his eyes focusing through the spiderwebbed fractures of his fragile viewport. Standing beside a stripped-down, open-frame utility tug named *The Riveter* was Ramirez Nails. She was a towering presence even in her scuffed, weld-splattered EVA suit. Her muscular frame, usually covered only by a sleeveless thermal undersuit and a grease-stained bandana when she was working inside the pressurized market containers, was now encased in heavy-duty industrial plating. In her right hand, she held her prized custom tool: a dual-chamber resin injector that could cure structural foam in under three seconds.

"I’ve seen better days, Ramirez," Mark rasped, his voice a dry, metallic wheeze. "But the clock is ticking. We have under eight hours of oxygen left in the pod for Sarah and Toby. We need that second fuel cell from Silas."

Ramirez spat a stream of synthetic stimulant gel into her suit’s waste-reclamation tube, her dark eyes narrowing through her visor. "Silas is a paranoid snake, but he’s the only one with refined hydrazine in this sector. If he says there’s a cargo of volatile ammonia coolant in the Frozen Coolant Cloud, he’s not lying. He’s just too cowardly to send his own runners. That place is a chemical bomb waiting for a spark. You ready to play fire-marshal in a vacuum?"

"No choice," Mark said, securing the single fuel cell into *The Riveter's* cargo netting. "Let’s get moving."

Mark climbed onto the open-frame passenger bar of *The Riveter*, securing his safety tether to the main structural rib. He carried his personal harness with the Modified Magnetic Grapple Claw mounted to his chest frame. The claw’s winch gears were still fused solid, melted into a distorted block of steel from the extreme friction of their last high-speed deceleration. The ninety-meter carbon-fiber cable was locked in a half-retracted state, trailing behind him like a dead, silver wire. He couldn't use the winch to reel anything in, but the magnetic claw itself was still functional as a static anchor. It was a clumsy, restricted setup, but in the Graveyard, you worked with the tools you had.

Ramirez fired *The Riveter’s* low-output thrusters. The utility tug drifted out of Docking Lane Seven, its RCS thrusters emitting tiny, controlled white plumes of nitrogen gas as it navigated past the towering, rusted hull of the dead Saturn rocket booster. They left the flickering amber sodium lights of Maeve's Outpost behind, plunging back into the pitch-black shadows of Sector 4.

Ahead of them, the sun was beginning to rise over the curved, glowing blue horizon of Earth, casting a harsh, blinding glare across the floating graveyard of dead satellites and shattered space stations. But as they approached their target coordinates, the brilliant sunlight began to scatter and dim, filtered through a massive, glittering haze that stretched across several kilometers of orbit.

They were entering the Frozen Coolant Cloud.

It was a beautiful, terrifying wasteland. Decades ago, a catastrophic cooling system failure on an Earth-Coalition research station had released tons of pressurized ammonia and hydrazine. In the absolute cold of space, the liquid had instantly frozen, transforming into a dense, chaotic swarm of razor-sharp, yellow-tinted ammonia crystals and drifting, unpressurized hydrazine tanks. The crystals glittered like a field of shattered glass in the sunlight, reflecting a cold, pale yellow light that cast long, distorted shadows across the surrounding debris.

*PING. PING. PING.*

Tiny, abrasive frozen ammonia crystals began to rattle against Mark’s helmet visor, scratching the high-tensile glass and leaving microscopic white pits that obscured his vision. The sound was a continuous, metallic static that vibrated directly through his skull.

"Switching on the analyzer," Mark muttered, his gloved fingers fumbling with the controls of the Portable Gas Analyzer mounted to his chest harness. The device hummed to life, its laser absorption spectrometer scanning the surrounding vacuum.

Instantly, the analyzer’s display flashed a bright, warning orange. The digital readout began to climb, displaying a rapid succession of chemical signatures.

"We’ve got high concentrations of ambient hydrazine gas in this sector," Mark reported, his voice tight. "The solar radiation is heating the outer edges of the cloud, causing the frozen fuel pockets to sublimate. Ramirez, keep your thruster output to the absolute minimum. A single hot plume could ignite the ambient gas and trigger a chain-reaction explosion that will vaporize this entire block."

"Copy that, Kelly," Ramirez grunted, her hands rock-steady on the manual flight sticks. "I'm shutting down the active chemical thrusters. We'll drift in on cold nitrogen. But you better find that radiator line fast. My suit’s thermal regulators are already fighting the ammonia frost. It’s eating through the seal lubricants."

*The Riveter* drifted silently into the yellow-tinted haze, its speed dropping to a cautious crawl. Mark held the gas analyzer ahead of him, using the real-time sensor telemetry to map the safest cutting vectors. The cloud was a maze of chemical hazards; pockets of highly volatile hydrazine gas drifted like invisible clouds of poison, detectable only by the rapid chirping of his analyzer.

Through the glittering storm of crystals, the shattered wreckage of the research station’s cooling array emerged from the dark. It was a chaotic tangle of twisted aluminum pipes, shattered solar panels, and massive, rusted radiator panels that drifted in a slow, clockwise rotation. The primary coolant lines—thick, insulated conduits designed to carry supercooled ammonia—were caked in a thick, yellow crust of chemical ice.

Ramirez brought *The Riveter* to a halt three meters from the radiator array, securing the tug’s manual docking clamps to a stable structural beam. "There's our target," she said, pointing her heavy resin injector toward a central manifold where four pressurized coolant canisters were locked in their mounting brackets. "The lines are still pressurized, Kelly. Look at the expansion on those joint fittings. If we cut those pipes without stabilizing them, the pressure drop will cause the frozen alloy to shatter."

Mark unclipped himself from the passenger bar, his boots drifting free of the metal frame. He used his manual grapple claw as a static anchor, hooking the half-retracted cable to a nearby structural rib to keep himself positioned. Every movement of his hands was a struggle; the raw, blistered skin of his right palm stung as it rubbed against the inside of his suit glove, and his frostbitten left thumb remained a useless, deadened weight.

"Toby and Sarah are down to six hours of air," Mark said, his breath fogging the scratched glass of his visor. "Let's get to work."

He pulled out a set of heavy, automated mechanical shears from *The Riveter's* tool rack, aligning the steel jaws with the primary coolant line’s safety collar. He squeezed the manual trigger. The electric motor hummed, the jaws biting into the yellow-crusted metal.

*SNAP.*

A sharp, metallic crack echoed through Mark's suit. The frozen alloy of the coolant pipe was too brittle from the extreme cold; instead of cutting, the metal resisted, and the shear's high-carbon steel blades snapped cleanly in half, sending shards of metal drifting into the void.

"Damn it," Mark cursed, discarding the useless tool. "The metal is crystallized. Shears won't work. I have to use the plasma torch."

"Are you crazy, Kelly?" Ramirez barked over the comms, her voice rising in alarm. "The analyzer is showing hydrazine levels at forty percent in this pocket! If you ignite that torch, the thermal heat will trigger an explosion!"

"Not if I manage the heat," Mark said, his mind calculating the thermal thresholds. He reached for his Industrial Plasma Welding Torch, his fingers adjusting the manual gas valve on the handle. "Standard high-heat cutting will ignite the ambient gas instantly. But if I use a pulsed, low-temperature plasma arc, I can cut the outer collar without reaching the ignition threshold of the hydrazine. I’ll allow the metal to cool for five seconds between each pulse. It’ll take longer, but it’ll keep the local temperature below two hundred degrees."

Ramirez stared at him through her pitted visor, then shook her head. "Your funeral, systems engineer. I'll stabilize the pipe fittings while you cut. If I see a thermal bloom, I’m cutting your tether and running."

"Fair enough," Mark said.

Ramirez drifted toward the manifold, her custom dual-chamber resin injector held ready. She aligned the nozzle with the rusted, expanding joint fittings of the coolant line. With a sharp, pneumatic *hiss*, she injected a thick stream of high-viscosity structural resin around the pipe. The grey foam expanded instantly in the vacuum, wrapping around the stressed metal and hardening into a rigid, airtight sleeve in under three seconds.

"Fittings are stable," Ramirez said, her breathing heavy over the comms. "You've got your structural support, Kelly. Make your cut."

Mark positioned himself close to the primary valve, his right hand gripping the over-clocked handle of the plasma torch. He aligned the magnetic nozzle with the frozen collar. His blistered palm throbbed with white-hot agony as he squeezed the manual igniter.

*ZAP.*

A brilliant, localized blue plasma arc flared in the dark, illuminating the yellow ammonia crystals drifting around them like a swarm of angry hornets. The gas analyzer's alarm began to chirp in his helmet—a rapid, high-pitched warning that signaled a sudden rise in local temperature.

Mark held the arc for exactly two seconds, watching the steel collar glow a faint, dull red. Then, he cut the power.

"One," Mark counted, his breathing shallow as he watched the temperature readout on his suit display. "Two. Three. Four. Five."

The red glow on the metal faded, dissipated by the extreme cold of the surrounding vacuum. The analyzer's chirping slowed.

He squeezed the igniter again.

*ZAP.*

Another two-second pulse. The plasma arc sliced a fraction of an inch deeper into the crystallized alloy. Mark's hands shook with the effort of maintaining absolute precision; a single slip of the torch would slice into the pressurized ammonia line, triggering an explosive decompression that would shred his suit.

"You're cutting it close, Kelly," Ramirez muttered, her eyes fixed on her resin injector as she monitored the structural sleeve. "We've got a drifting chunk of solar panel debris heading our way. It's kicking up a cloud of ammonia dust."

Mark ignored the warning, focusing entirely on the narrow seam of his cut. "Keep the pipe stable, Ramirez. Almost through."

*ZAP.*

On the fourth pulse, a drifting, razor-sharp ammonia crystal—no larger than a pebble but traveling at high orbital speed—struck the magnetic nozzle of Mark’s plasma torch.

*SPARK.*

A brilliant, localized electrical arc flared between the nozzle and the frozen pipe. The sudden surge sent a violent jolt of static feedback directly up the torch handle, scorching Mark’s right palm once more and scrambling his suit's telemetry displays. The digital screens inside his helmet flickered with green static, and the gas analyzer emitted a continuous, deafening shriek of warning.

Mark gasped, his body jerking in his harness, but he forced his fingers to remain closed around the torch. He didn't let go. He held his position, using his weightless momentum to damp the recoil.

"Kelly!" Ramirez yelled. "Your thermal signature just spiked!"

"I'm fine!" Mark rasped, his lungs burning as he struggled to draw air through his suit's laboring regulator. "The cut is complete. The collar is sheared."

He reached out with his clumsy, frostbitten left hand, using Robert Vance's titanium wrench to manually pry the sheared collar off the valve. The metal yielded with a silent, heavy groan. Mark reached into the manifold and pulled the first pressurized ammonia coolant canister free from its mounting bracket.

It was a heavy, cylindrical container caked in frozen yellow frost, its pressure gauge displaying a stable, supercooled state.

"One secured," Mark said, his voice trembling from the physical exertion. He passed the canister to Ramirez, who quickly locked it into *The Riveter's* cargo frame.

"We need three more to fulfill the contract," Ramirez said, her eyes scanning the dark, yellow-tinted void. "The hydrazine levels are rising, Kelly. The solar radiation is hitting the core of the wreck. We don't have time for another pulsed cut."

"We don't have a choice," Mark said, his hand throbbing in silent agreement as he aligned the plasma torch with the second valve collar. "If we run now, we freeze in Maeve's docks. We finish the job."

For the next fifteen minutes, they worked in a silent, high-stress rhythm. Mark executed the pulsed, low-temperature cuts, his blistered hands screaming with every squeeze of the igniter, while Ramirez applied her structural resin to stabilize the expanding joints. One by one, they harvested the second and third coolant canisters, securing them to the utility tug.

By the time Mark aligned his torch with the fourth and final canister, his suit’s battery display was flashing a warning: *Power Capacity 50%*. His physical stamina was pushed to its absolute limit; his joints ached from his moderate radiation exposure, and his breathing was a heavy, ragged gasp that struggled to clear the carbon dioxide from his helmet.

"Last one, Nails," Mark whispered, his right palm slick with warm, sticky fluid inside his glove where his blisters had burst. "Keep it steady."

Ramirez aligned her injector, applying a final, thick sleeve of grey resin around the rusted manifold. "Secure, Kelly. Cut it."

Mark squeezed the igniter, the blue plasma arc flaring for the final time. He sliced through the metal collar with clinical focus, ignoring the blaring alarms and the scratch of ammonia crystals against his visor. With a final, manual pry of his wrench, the fourth coolant canister popped free from its bracket.

Ramirez grabbed the canister, her muscular arms securing it into the final cargo slot on *The Riveter's* frame. "That's four, Kelly! We've got the cargo! Let's get the hell out of—"

She froze.

Through the scratched, pitted glass of his visor, Mark saw the real-time telemetry on his gas analyzer suddenly redline. The digital display didn't just climb; it flashed a blinding, continuous crimson warning.

*WARNING: UNCONTROLLED CHEMICAL DECOMPRESSION DETECTED.*

The thermal heat from Mark's plasma torch, despite his pulsed cuts and low-temperature precautions, had traveled along a hidden, unmapped structural pipe deep within the radiator array. The heat had reached a nearby, unmapped auxiliary hydrazine tank that had been buried behind a layer of frozen insulation.

The crystallized metal of the tank, weakened by decades of exposure and sudden thermal expansion, fractured.

*HISSSSSSSSSST.*

It was a sound that Mark felt rather than heard—a violent, high-frequency vibration that traveled directly through his grapple cable and into his suit frame.

A micro-fissure had ripped open along the seam of the unmapped hydrazine tank. Instantly, the superheated, highly volatile liquid inside flashed into a high-pressure jet of toxic gas, erupting into the yellow-tinted void with terrifying force.

The jet of expanding chemical poison was a brilliant, pale green plume that cut through the glittering ammonia cloud like a knife, shooting directly toward their carbon-fiber safety tethers.
