Deep-Dive: Starcloud Orbital Optical Laser Mesh Architecture

An architectural deep-dive into Starcloud 100Gbps inter-satellite optical laser routing mesh and liquid-to-vacuum thermal radiation panels.

Co-Engineered 100Gbps Free-Space Optical Transceivers

At the core of Starcloud space data center design is a 100Gbps free-space optical transceiver mesh. Each satellite maintains active laser tracking with four adjacent orbital nodes, forming a low-latency ring topology capable of transferring multi-terabyte AI model weights across orbital planes without terrestrial downlink hops.

Direct-Liquid-to-Radiator Heat Dissipation in Zero Gravity

Thermal management in the vacuum of space presents a distinct engineering hurdle. Starcloud uses closed-loop liquid cooling plates mounted directly onto custom inference ASICs, pumping dielectric fluid to expansive graphene-reinforced thermal radiator fins that dump excess heat via infrared radiation into deep space.

Software orchestration is handled by an edge Kubernetes control plane calibrated for orbital orbital mechanics, dynamically scheduling compute tasks as satellites pass over ground station downlinks.
