Elon Musk just unveiled SpaceXAI's first AI satellite.

• 150 kW peak power / 120 kW sustained compute power

• 150 kW solar array using SpaceX-manufactured solar technology

• Centralized AI compute payload designed for high-performance AI workloads

• 70-meter wingspan when fully deployed

• 110 m² deployable liquid radiators to remove waste heat in space

• Redundant cooling loops with integrated micrometeoroid shielding

• Designed to launch on Starship, enabling the mass-to-orbit needed for large-scale space computing

• Uses laser links while avoiding many of the complex communications systems required by Starlink satellites

• SpaceX believes future versions can scale far beyond this first design

Elon Musk says the path to scaling AI in space requires 3 things:

• Massive launch capability (Starship)
• Enormous solar power generation
• Large radiators to reject heat from AI chips

He also suggested that truly large-scale orbital AI could eventually require hundreds of gigawatts to a terawatt of power, implying millions of tons of infrastructure in orbit.
