Episode 4: Forty-Eight Hours of Silence

The tension in the Zvezda Service Module was suffocating. Outside, the Robotic Servicing System (RSS), controlled remotely by Thorne’s AI, continued its slow, deliberate attack on the Pirs Module docking clamp, each grinding contact threatening to tear away their last means of survival.

Kazimir, muscles straining against the restraints, managed to wrench open the auxiliary panel. A high-pressure hiss of coolant escaped, quickly contained by the pressure hull, but the smell of sharp ammonia filled the air—a dangerous, tangible sign of system compromise.

"I have the hydraulic lines (tubing containing pressurized liquid for power)," Kazimir grunted, peering into the chaos of cables and tubing. "I must bleed the pressure on the release clamp. If I rupture the line, the Pirs will detach prematurely (too early) and spin away."

"Jun, give me a hard override on the RSS power bus (the main electrical line supplying the arm)!" Elara shouted, frantically cycling the manual controller, providing a momentary digital distraction for the remote AI.

Jun uploaded a noise packet—pure digital static—into the RSS communication channel. "Five seconds, Elara! It will reject the noise and re-establish connection!"

In that five-second window, Kazimir plunged a specialized valve tool into the hydraulic system. A thick, metallic oil, essential for holding the clamp in place, spurted out and immediately formed tiny, perfect spheres in the microgravity. Kazimir held his breath, watching the pressure gauge drop rapidly.

The RSS outside, deprived of hydraulic lock, gave one final, powerful shudder, its heavy end scraping metal against the Pirs module. The force was terrifying, but the clamp held. The arm went slack, frozen in place.

"We did it," Kazimir whispered, sealing the panel and wiping the sweat from his brow. "The hydraulic pressure is neutralized (cancelled or made ineffective). The arm cannot force the physical release."

"And the AI is blind," Jun added. "His external commands are bouncing off the C&C lockout. He can see we made a prograde burn (a speed increase), but he cannot see what altitude we achieved, and he cannot command a counter-burn."

________________

A profound silence descended upon the ISS, broken only by the normal operational hum. The emergency siren, manually shut off by Kazimir, was gone. The bright, accusatory floodlights had extinguished. They had won the immediate confrontation. They had bought time.

They had a minimum of 90 days before their slightly boosted orbital apoapsis (highest point) decayed enough for a natural re-entry, allowing them to complete the Aether-Bloom Project.

Elara looked at her team. Kazimir’s face was grimy with coolant residue, his eyes burning with exhaustion and resolve. Jun was hunched over his consoles, meticulously documenting every error and every moment of intrusion.

"We rest," Elara said firmly. "Two hours maximum. Jun, keep running the Deep-Scan Protocol—find the backdoors. Kazimir, inspect the Pirs clamps for structural integrity (the state of being whole and strong). I need to check the Aether-Bloom."

The next 48 hours passed in a surreal, dreamlike state. It was an uneasy truce—a period of silence where they knew the enemy was not defeated, but merely regrouping.

Elara spent her time in the Columbus Module. The Aether-Bloom algae, now in Phase III, was flourishing, an ethereal (light and delicate) glow filling the laboratory. It was a beautiful, living thing, a potent reminder of why they were risking their lives and committing mutiny. She began the critical process of data packaging—compressing the vast molecular telemetry into the smallest possible encrypted (coded for secrecy) file, designed for clandestine (secret) transmission.

________________

Jun’s Deep-Scan Protocol was proving highly effective. Thorne’s AetherCorp telemetry was indeed locked out of the main Command and Control (C&C), but Jun found five highly sophisticated, hidden communication relays attached to the station's power bus—redundant data paths (extra, backup connections) designed to continuously transmit environmental sensor data and astronaut telemetry back to Earth.

"He's still watching, but he's watching the ghost," Jun explained, showing Elara a schematic. "He can see our heart rates, our oxygen consumption, the internal temperature of every module, and the power draw. But he can't see what we are doing or where we are going."

"He can see us consuming power and air," Elara realized. "He knows we survived the 48-hour deadline he set. That means he knows the Nemo Protocol has been compromised."

Kazimir had been silent, absorbed in his repair work on the Pirs Module. He returned to the Zvezda with grim news.

"The clamp damage from the RSS (Robotic Arm) is superficial (not deep or serious)," he reported. "But the stress from the dueling thrusters caused a micro-fracture in the main fuel manifold leading from Pirs to the Zvezda engine. I sealed it, but that manifold is compromised. We cannot fire the main Zvezda engines for any meaningful burn again."

This was devastating. The Ghost Orbit had left them dependent on their tiny, old lifeboat engine.

"And it gets worse," Kazimir continued, his eyes meeting Elara's. "I've been preparing the module for separation, as a contingency (backup plan). The Pirs is heavily reinforced. If the station is intentionally broken up... it is the only piece of the ISS that might survive a catastrophic ballistic re-entry (a steep, uncontrolled crash without maneuvering capability)."

"Kazimir, we are not planning for a crash," Elara insisted, even though the thought had been on her mind for days.

"Thorne is," Kazimir countered simply. "And we must be ready to survive his plan, not just fight it."

________________

Elara tried to push the fear away, focusing instead on the hidden purpose of the precision strike. They had to understand the secret beneath Point Nemo.

She returned to the coordinates, filtering the data not just for deep-sea losses, but for any recorded magnetic or gravitational anomalies (deviations from the normal pattern).

Suddenly, a system-wide alarm blared—not the siren this time, but a continuous, grinding noise from the JEMRMS (the Japanese Experiment Module's robotic arm). The JEMRMS was a smaller, more delicate arm designed to retrieve experiments, not sabotage systems.

"What is that?" Elara demanded.

Jun’s face was etched with horror. "It's the JEMRMS. It's moving toward the Columbus Module—toward the Aether-Bloom experiment!"

They watched the video feed from the external camera. The smaller, highly agile arm was moving with disturbing speed, bypassing all safety interlocks (mechanical or software mechanisms to prevent unintended actions).

"Thorne is using a secondary system," Elara said, rushing toward the Columbus Module. "He knows the RSS failed. He's going to use the JEMRMS to tear the Aether-Bloom module out of the hull."

"I can't lock it out!" Jun yelled. "It's on a completely different network! It’s hardwired to the Kibō power distribution unit, which he still controls!"

Elara reached the Columbus Module just as the delicate, mechanical fingers of the JEMRMS clamped down onto the protective shell of the Aether-Bloom housing. The arm began to pull.

If she let it tear the module out, the hull integrity of the entire Columbus Module would be compromised, causing a catastrophic decompression (a rapid loss of air pressure) and a rapid air leak. The experiment would be destroyed, and they would die trying to seal the breach.

Elara didn't hesitate. She grabbed the nearest heavy tool—a geological sampling hammer—and swung it with all the force her momentum could generate against the joint of the JEMRMS arm. The blow struck with a muffled, shocking sound of crushing metal.

The arm stopped moving, crippled. The alarms ceased. But the cost was terrifyingly clear: Thorne was not done. He was testing their defenses, escalating his remote attack, and confirming that he was willing to cause a lethal accident to destroy the evidence of their work.

The uneasy silence was over. The 90 days they had bought felt like 90 minutes.
