The pale green plume of hydrazine gas cut through the yellow haze, a silent executioner heading straight for their safety lines.

Inside his sealed yellow-and-gray EVA suit, Mark Kelly watched the gas analyzer’s display flash a frantic, strobe-like crimson. The digital readout was climbing with terrifying speed: forty-one percent, forty-two percent. The sublimating fuel from the fractured auxiliary tank was expanding into the unpressurized void of the Frozen Coolant Cloud, turning their immediate perimeter into a highly volatile chemical minefield. A single spark from his Industrial Plasma Welding Torch, a solitary hot plume from a thruster, or even a static discharge from a damaged suit wire would turn this pocket of space into a blinding fireball that would vaporize both him and Ramirez Nails in a microsecond.

"Kelly! We’ve got to cut and run!" Ramirez’s voice crackled over the short-range suit comms, her breath coming in heavy, jagged gasps. "That hydrazine is drifting spin-ward. It’s going to envelope our main tethers in less than thirty seconds!"

Mark’s left hand, waxy and stiffened by the waxy-white frostbite on his thumb, throbbed with a dull, nauseating heat inside his glove. His right palm, raw and bleeding where his blisters had burst during their previous escape, stung with white-hot needles as he gripped the metal structural bar of *The Riveter*. "We can't fire the active chemical thrusters, Nails. The exhaust heat will ignite the cloud. We have to use the manual nitrogen bypass to drift out of the plume’s path."

But before Ramirez could reach for the cold-gas manifold, a shadow detached itself from the dark, silent bulk of a dead communication satellite hovering just fifty meters above them.

It was a scuffed, asymmetrical salvage rig, its hull a patchwork of rusted steel plates and exposed, sparking wiring. Written across its nose in faded, grease-smeared stencils was the registry of an independent scrapper. Behind the scratched, yellowish visor of the approaching vessel's cockpit sat Rusty Vance. His greasy, unkempt beard pressed against his helmet’s inner glass, and his yellowed teeth were bared in a silent, predatory grin.

Rusty didn't hail them. He didn't need to. In the outer ring, where every breath of oxygen had a price tag, the law of the void was absolute: what is unpressurized belongs to whoever can weld their tether to it first. And Rusty had been tracking *The Riveter's* thermal plume, waiting like a vulture for Mark and Ramirez to do the grueling, dangerous work of harvesting the four volatile ammonia coolant canisters now locked into the tug's cargo frame.

With a silent, mechanical jerk, Rusty’s rig deployed its primary tool—a heavy, custom-built pneumatic wire-cutter designed to silently slice through carbon tethers. The cutter’s high-carbon steel blades, caked in frozen hydraulic oil, began to cycle, opening and closing in a slow, rhythmic snap that was terrifyingly silent in the vacuum.

"Rusty, you son of a bitch!" Ramirez snarled, her hand flying to her custom dual-chamber resin injector. "Back off! We harvested these canisters! Silas paid for them!"

Rusty’s rig ignored her, its cold-gas attitude thrusters emitting tiny, precise white puffs of nitrogen as it drifted closer. The heavy wire-cutter arm extended, aligning directly with the carbon-fiber safety line connecting Ramirez's suit to *The Riveter’s* structural rib.

Mark’s mind raced, calculating the velocities and masses in a fraction of a second. "Ramirez, jump!" he roared.

But the warning came a heartbeat too late.

With a dull, shuddering vibration that traveled through the metal frame of the tug, Rusty’s pneumatic cutter snapped closed. The high-tensile carbon-fiber of Ramirez’s auxiliary safety tether parted instantly, the severed ends whipping violently into the dark like struck snakes. The sudden release of tension launched Ramirez backward, her weightless body tumbling out of control into the glittering, yellow-tinted cloud of frozen ammonia crystals.

"Kelly!" she cried out, her dual welding torches flailing as she tried to find an anchor point in the empty air. Her main line was still attached to the cargo frame, but without her auxiliary stabilizer, she was spinning spin-ward, directly toward the expanding green plume of toxic hydrazine.

Mark lunged forward, his blistered right hand grabbing the frame of *The Riveter* to keep himself from being pulled into the spin. He wanted to ignite his plasma torch to cut the cutter arm off Rusty's rig, but the gas analyzer in his helmet was screaming, its pitch rising to a deafening, continuous shriek. The hydrazine level was at forty-four percent. If he pulled the trigger on the torch, the resulting blue plasma arc would ignite the ambient gas, killing them all instantly.

He had to use kinetic force. He had to use Newtonian momentum.

But his Modified Magnetic Grapple Claw was severely restricted. The intense friction of their previous deceleration had heated the winch assembly, melting the high-tension steel gears into a single, fused block of distorted metal. The ninety-meter carbon-fiber cable was locked in a half-retracted state, trailing behind *The Riveter* like a dead, silver wire. He couldn't reel it in, and he couldn't release it. It was a static, unyielding line.

Mark looked through the spiderwebbed fractures of his fragile viewport, searching the chaotic debris field. Through the glittering haze of ammonia ice, his eyes locked onto a drifting, two-hundred-kilogram block of frozen ammonia that had sheared off the research station’s primary radiator array. It was floating silently just thirty meters away, moving at a relative velocity of three knots.

*Kinetic Trajectory Snaring,* his father’s voice echoed from the old engineering handbook memorized in his youth. *If the winch is fused, your body is the counterweight. Use the tension. Use the swing.*

Mark unclipped his main safety harness from *The Riveter’s* bar, relying entirely on his manual grip. With his injured right hand, he raised the grapple claw's heavy, industrial-grade launcher, aligning the magnetic prongs with the drifting block of ammonia ice. He ignored the white-hot agony that shot up his forearm as his popped blisters rubbed against the coarse fabric of his glove. He squeezed the manual pneumatic trigger.

*PHUT.*

The grapple claw launched, the static ninety-meter cable trailing behind it in a perfect, shimmering arc through the yellow haze. The electromagnetic prongs struck the center of the frozen ammonia block with a silent, metallic impact, locking onto the dense, icy mass with a powerful magnetic snap.

"Hold on, Ramirez!" Mark shouted.

With the cable locked to the drifting block, Mark threw his weightless body backward, looping the high-tensile line around *The Riveter’s* forward structural brace. He became the human pulley, using his own muscular strength and the reinforced frame of the tug to transfer the momentum of the moving ammonia block.

As the cable snapped taut, the kinetic energy of the two-hundred-kilogram ice block transferred instantly into the line. The tension was absolute. Mark’s shoulders groaned under the sudden, violent G-force, his joints screaming as the waxy skin of his frostbitten left thumb threatened to tear under the pressure. But he held on, his boots locked into the tug’s foot-straps.

The trajectory of the frozen block altered instantly. Anchored by the static cable, it began to swing in a rapid, centrifugal pendulum arc, accelerating as it cleared the yellow haze of the cloud. It was a perfect kinetic hammer, moving without sound through the silent void, heading straight for Rusty Vance’s cockpit.

Rusty’s eyes widened behind his yellowish visor. He scrambled for his cold-gas controls, attempting to back his rig away from the incoming projectile, but the heavy, un-steered salvage rig was too slow to break its momentum.

*CRASH.*

The silent impact was devastating. The massive block of frozen ammonia struck the forward assembly of Rusty’s rig, shattering the primary hydraulic seals of the wire-cutter arm. A violent cloud of frozen hydraulic fluid and metal shrapnel erupted into the dark, glittering like diamonds in the sun. The force of the blow sheared the cutter arm cleanly off its mount, sending it spinning into the void, while the rig itself was launched spin-ward, tumbling out of control toward the outer boundary of the sector.

Rusty’s severed winch cable, still attached to the shattered assembly, whipped violently through the dark, a jagged steel wire traveling at high velocity.

Mark saw the cable coming, a silver blur reflecting the harsh sunlight, but in zero-G, with his body strained and his hands locked to the frame, he had no way to dodge.

*CLANG.*

The heavy steel end of the severed cable struck the left side of Mark's helmet with a sickening, metallic impact that vibrated directly through his skull. The force of the blow launched his head back, his vision flickering with bright, colorful static as his brain slammed against his skull.

He gasped, his lungs searching for air, but the sound that returned was a terrifying, high-pitched whistle.

Through the spiderwebbed fractures of his fragile viewport, Mark watched a new, deep web of cracks expand across his outer visor. The impact had shattered the outer seal of his helmet.

*Pssssssssst.*

The cold, wailing whistle of escaping gas vibrated through his ears. His suit's primary pressure display began to drop: seventy-two kilopascals, seventy, sixty-eight. A slow, whistling oxygen leak was draining his life support directly into the cold, unfeeling void. He had less than ten minutes of breathable air remaining, his vision was partially obscured by the expanding fractures, and they were still trapped in the volatile heart of the Frozen Coolant Cloud with no active propulsion.
