# Zhejiang Lab

**Type:** Research Lab  
**Domain:** Space Development (AI/Computing)  
**Status:** Active  
**Country:** China

## Overview

Zhejiang Lab is a major Chinese AI research institution, comparable to a national AI laboratory. The lab partners with ADA Space and CASIC on the Three-Body Computing Constellation program, providing AI model development and research capabilities for orbital computing applications.

## Timeline

- **2025-05-14** — Three-Body constellation launch (12 satellites) with Zhejiang Lab AI models
- **2026-02-16** — Validated 8-billion-parameter remote sensing LLM and 8-billion-parameter astronomical time-domain model in orbit with 94% classification accuracy

## Technical Contributions

Zhejiang Lab developed the AI models running on the Three-Body constellation:
- 8-billion-parameter remote sensing LLM
- 8-billion-parameter astronomical time-domain model
- Among the largest parameter counts of any operational in-orbit AI globally as of February 2026

## Strategic Role

Zhejiang Lab's involvement demonstrates China's strategy of integrating national AI research capabilities with commercial space infrastructure development, creating civilian-led programs with state research support.
