In May 2025 China launched twelve satellites that were not there to relay phone calls or fix positions. They were the first pieces of the “Three-Body Computing Constellation”, an attempt to build an artificial-intelligence supercomputer in orbit, each satellite a node running AI on the data it collects rather than shipping it home first.[1]
The project, led by Zhejiang Lab with the Chengdu company ADA Space, is planned to grow to some 2,800 satellites delivering a combined 1,000 peta-operations per second, a quintillion operations a second of orbital compute.[2][1] The first twelve already provide around five peta-operations between them, each carrying an onboard AI model of up to eight billion parameters and linked by laser at up to 100 gigabits per second.[3][4]
Today, satellites are eyes that must phone home. The bet here is to give them a brain, and let them think in orbit.
Why compute in space at all
The logic is bandwidth. By the project’s own framing, less than a tenth of the data satellites gather is ever transmitted to Earth, bottlenecked by narrow ground-contact windows and limited downlink.[4] Processing imagery and sensor data in orbit, sending down answers rather than raw feeds, sidesteps the bottleneck, and abundant solar power and the cold of space help with the energy and cooling that ground data centres struggle to supply. It is a genuinely novel idea, pursued at national scale.
The caveats are the honest measure of it. Only twelve of a planned 2,800 satellites are flying; the full system is a projection, not a fact. And while the headline numbers come from an official announcement, the granular specifications sit in secondary reporting, solidly corroborated, but worth citing as attributed rather than audited.
What it means for capital
Space-based computing is the most speculative and most interesting item in this section — a frontier bet rather than a proven market, and one where China has taken a visible early lead. If in-orbit AI compute becomes real infrastructure, it stitches together the two themes this firm watches most closely, artificial intelligence and space, into a single new category with obvious dual-use weight. The discipline is to hold ambition and evidence apart: twelve satellites are a demonstration, not a supercomputer, and 2,800 is a plan. We track it as optionality on a genuinely new idea, small today, potentially foundational, and worth understanding early precisely because almost no one is.
