About Exlumina
Exlumina is a space technology company founded on August 21, 2023. Exlumina is developing solar-powered orbital infrastructure for AI inference, with the goal of reducing the grid power and cooling limits that constrain terrestrial AI data centers.
The Exlumina FlatSat concept brings compute, solar power and deployable radiators into a modular spacecraft architecture. Current work focuses on engineering development and ground validation ahead of future orbital demonstrations. Hardware selection and performance figures are under evaluation, and communications interfaces are in development. Edge compute for partner satellites, running inference next to the sensor instead of downlinking raw data, is a proposed secondary capability.
Use Cases
- General-purpose AI inference for LLMs, vision models, and autonomous agents
- Foundation model serving from orbit on solar-powered GPUs
- Data processing concepts engineered around strict isolation, encryption, and access-control requirements
- Sensor fusion for defense and intelligence
- Edge inference for partner satellites, Earth observation and telemetry processed in orbit
- Persistent autonomous AI agents
- Scientific computing and climate modeling
Key Differentiators
On-Orbit Processing: The proposed concept aims to reduce Earth-bound data transfer by transmitting only actionable results.
Continuous Connectivity Goal: Communications interfaces are in development around laser inter-satellite links, intended to reduce brief ground station pass constraints.
GPU-Class Compute in Space: The proposed architecture evaluates the same class of NVIDIA GPU hardware used in terrestrial data centers.
Security Engineering: Isolation, encryption, and controlled access are engineering requirements built into the design for sensitive data processing.
Technology, Space-1 Vera Rubin Module
The Space-1 satellite platform concept is being developed around NVIDIA's Vera Rubin compute architecture, as a radiation-tolerant, thermally managed spacecraft module intended for long-duration operation in Sun-Synchronous Orbit.
Core Specifications
- CPU: Under evaluation (Vera-class proposed)
- GPU: Under evaluation (Rubin-class proposed)
- AI Inference: Under evaluation
- GPU Memory: Under evaluation
- Memory Bandwidth: Under evaluation
- Interconnect: Under evaluation (NVLink 6 proposed)
- Orbit: Mission-specific analysis (SSO 500-600 km evaluated)
- Connectivity: In development
- Operating System: TachyonOS (software development)
Thermal Management
Heat dissipation in the vacuum of space is being designed around deployable radiator panels and phase-change thermal interfaces, intended to support sustained GPU compute loads.
Radiation Hardening
The compute module incorporates ECC memory, watchdog timers, and autonomous recovery sequences to maintain operation through the radiation environment of Low Earth Orbit.
