Milestone stage: deployment
partially-demonstrated
Small accelerator payload operation in orbit is demonstrated; megawatt clustering remains unknown.
Completion criteria: Operational telemetry and customer/research workloads verify a minimum 1 MW computing input sustained over thirty days, including thermal handling, communication, failure recovery and power accounting. A small accelerator satellite is a precursor only.
