Starcloud’s orbital data center architecture centers on Starlink laser links and a four-component satellite system—solar panels, radiators, GPUs, and laser terminals—building on Starcloud-1’s NVIDIA H100 compute and Starcloud-2’s anticipated power and cooling to scale computing in space.

Near-term, the intersatellite mesh enables real-time data processing in orbit, supporting weather, wildfire, and Earth observation use cases without constant ground transmission.

The optical laser mesh connects solar power, radiators, GPU compute, and laser connectivity, with Starcloud-1 already proving NVIDIA H100 and Starcloud-2 expected to deliver 100× power generation and cooling within eight months.

Co-Founder and CEO Philip Johnston describes the collaboration as providing continuous, high-bandwidth, low-latency connectivity that effectively turns Starcloud satellites into a distributed data center.

The Starlink laser crosslinks enhance space safety by providing precise ephemerides and better data sharing, reducing collision risk through improved coordination.

The collaboration aims to deliver high-bandwidth, low-latency in-orbit processing for real-time applications like weather forecasting, wildfire detection, and Earth observation analytics, reducing reliance on ground downlinks.

Each Starcloud satellite will carry two Starlink Mini Laser terminals, enabling up to 25 Gbps of continuous intersatellite connectivity over up to 4,000 km and creating direct optical links without ground stations.

These terminals enable high-speed intersatellite links at varying distances, with maximum throughput of 25 Gbps over thousands of kilometers, reducing dependence on ground infrastructure.

The optical backbone is designed to support Earth-uplinked AI workloads, including inference and training, while leveraging space-based green energy to ease terrestrial grid stress.

Over the long term, the optical backbone will back AI workloads uplinked from Earth and contribute to space safety through enhanced data and ephemeris sharing and collision risk reduction.

Starcloud has contracted SpaceX’s Starlink to integrate Starlink Mini Laser terminals across more than 25 satellites, with over 50 terminals planned and first hardware expected on orbit within about a year.

Starcloud is building in-space data centers to address AI energy bottlenecks, launched Starcloud-1 in late 2025 with an NVIDIA H100, and recently raised a $170 million Series A at a $1.1 billion valuation led by Benchmark, anchored in Redmond, WA.
