Shanghai launches Mingzhu Constellation plan for gigawatt-scale space computing

The significance lies less in the satellite count than in the framing: Shanghai is treating orbital compute as public infrastructure, pairing domestically produced payloads with optical computing and new energy systems under an explicitly "independently controllable" mandate. That places the plan closer to strategic supply-chain policy than to a commercial constellation play, and it pulls China's launch, photonics and power sectors into one procurement narrative. The open question is verification: in-orbit testing of optical and energy payloads is the gate before any networking scale, and whether those milestones hold will shape how quickly space-based compute moves from pilot to infrastructure.
