# Orbital edge compute for space-to-space relay reached operational deployment (TRL 9) in January 2026 with SDA-compatible nodes, validating inference-class processing as the first commercially viable orbital compute use case

The first two orbital data center nodes launched to LEO on January 11, 2026, as part of Kepler Communications' optical relay network. These nodes enable 2.5 Gbps optical intersatellite links (OISLs) meeting Space Development Agency (SDA) Tranche 1 interoperability standards. The compute hardware runs processing/inferencing tasks: filtering images, detecting features, compressing files, and running AI/ML models on data from other satellites. This is operational deployment (TRL 9), not demonstration. Critically, these are edge inference nodes embedded in a relay network, not standalone data-center-class training infrastructure. The use case is processing satellite data in orbit to reduce downlink bandwidth requirements and enable faster decision loops for connected spacecraft. By 2027, at least three interconnected, interoperable ODC nodes are planned. This validates that the first economically viable orbital compute application is edge processing for space assets, not replacement of terrestrial AI training data centers—a fundamentally different value proposition than the SpaceX 1M-satellite or Blue Origin Project Sunrise announcements suggest.

Kepler Communications launched 10 ODC-equipped satellites in January 2026, each carrying multi-GPU compute modules and terabytes of storage. By February 2026, multiple US operators were simultaneously running production workloads—the first month in history with multiple orbital data center operators active. TechCrunch reported in April 2026 that 'the largest orbital compute cluster is open for business' from a separate US operator.

China's Three-Body constellation represents a parallel operational deployment track, completing 9 months of testing by February 2026. Unlike Western deployments focused on edge compute nodes, Three-Body demonstrates large-scale AI model execution (8B parameters) with distributed computing across 12 satellites, suggesting different architectural approaches between US and Chinese orbital compute strategies.

TechCrunch reported on April 13, 2026 that 'the largest orbital compute cluster is open for business' — only 90 days after the first ODC nodes became operational on January 11, 2026. This represents a second-generation commercial deployment milestone, suggesting the ODC market is iterating faster than typical space infrastructure commercialization timelines (which normally span 3-5 years from first deployment to scaled operations).
