## Approach

- Orbit: Sun-synchronous LEO
- Architecture: Government-backed lab building a thousand-satellite space computing network with ADA Space and others; satellites compute in orbit and return results
- Power: Solar (not quantified)
- Cooling: Not disclosed
- Compute: About 5 POPS and 30 TB across the first 12 satellites (ADA figures); 10 AI models validated in orbit by early 2026
- Customers: Research and public applications: disaster monitoring, weather, natural resources
