Standardized Unit: 350 kg "Gross Packet" (200 kg Cargo + 150 kg Universal Service Sled)
The OLH is designed for 100% autonomous orbital assembly from 350 kg launch packets. To support the "Universal Service Sled" (USS), the station is structurally rated for a 350 kg Gross Release Mass.
Central Spine: Interlocking carbon-fiber segments with integrated cryogenic and fluid manifolds.
Reinforced Tethers: 5 km Technora cords with a 20% increased cross-section to maintain a 3.0 Safety Factor at 34 Gs.
Silicone Protection: A 0.5mm Silicone-Based Encapsulation (SBE) prevents Atomic Oxygen (AtOx) erosion and UV brittling of the tether fibers.
Variable Ballast: 100m rigid arms with a 17,800 kg water-glycol capacity to perfectly offset 350 kg payload transients.
The "Heart" of the station is a high-inertia kinetic battery and stabilizer.
Array: 12 carbon-fiber flywheels (6 counter-rotating pairs) providing 3-axis (2X, 2Y, 2Z) fail-operational redundancy.
Solar Input: 5.7 MW solar array provides the "fuel" for kinetic pumping and gyroscope acceleration.
Direct-Drive Stirling Recovery: Modular Stirling engines are mechanically coupled to the flywheel shafts. They harvest friction heat from the winches and purification boilers to maintain gyroscope RPM. (Status: Operational Testing for Vacuum Clutches).
The station utilizes its payload as a "virtual propellant," allowing for infinite orbit adjustments using only sunlight.
The Mechanism: Solar power drives the winches to "Snap" the payload inward during the prograde arc (adding energy) and uses regenerative braking during the extension to recover energy.
Momentum Exchange: By timing these internal movements, the station can counteract atmospheric drag or raise its orbit without exhausting chemical fuel.
Momentum Harvest: Major velocity gains are achieved by capturing high-energy USS units and releasing waste or retired components during the retrograde arc.
The OLH functions as a logistical trade hub for the interplanetary fleet.
Shield Recycling: Arriving USS units have their Abrasive Ceramic Shields stripped. The station uses surplus waste heat to grind and re-cast these shields for return-trip sleds or station reinforcements.
Gas Exchange: Docked ships deliver Nitrogen (N2) cargo (Earth-sourced) in exchange for the station's Surplus Oxygen (O2) (Asteroid-sourced byproduct of fuel production).
Purification Loop: Waste heat boils asteroid ice in a Centrifugal Boiler (for microgravity phase separation) to create purified ballast and life support water.
Lunar Ice Integration: If ice is located beneath the lunar surface, it can be launched and captured by the station. This serves a dual purpose: capturing the high-velocity ice adds vital momentum to the station, and it provides a critical, sustainable source of water for the Purification Loop and life support systems.
Atmosphere: A stable 21/79 Nitrox environment is maintained in inflatable Vectran/Kevlar modules for crew and docked vessel life support.
ECPS Propulsion: A bipropellant RCS system with vacuum-jacketed cryogenic tanks for emergency de-tumbling or collision avoidance.
Thermal Fuse: In extreme overheat scenarios, the station can vent a small volume of purified steam to vacuum for near-instant cooling.
Navigation (Scout Suite): High-precision LiDAR and asteroid-tracking telescopes manage the microsecond-timed magnetic release of 350 kg packets. Observation Validation (2026): Navigation algorithms are augmented using tracking profiles from China's Tianwen-1 capture of interstellar comet 3I/ATLAS near Mars, validating sensor response for hyper-velocity celestial targets.

Propellantless Tugging: Theoretically sound. The station's target mass is maintained at 530:1 relative to the 350 kg payload to ensure rotational stability during momentum exchange. [Confidence: High]
Regenerative Braking: Feasible; requires high-efficiency motor/generators and thermal management via the Stirling loop. [Confidence: High]
350 kg Scaling: All structural math (Version 5.1) has been updated to reflect the heavier "Gross Packet" load from the Mountain Cyclotron. [Confidence: High]
Verified Tech: Stirling recovery is verified for high-heat environments; vacuum-rated magnetic clutches are currently in operational testing. [Confidence: Medium]
