Orbital Data Centers

Impact Statement

The payoff is on Earth: compute that does not draw cooling water from rivers and lakes. The flights so far prove chips can run in . They do not yet replace a terrestrial data center.

Explain Like I'm 10

What is it? Satellites that run AI chips on solar power and dump waste heat by radiating it into space, instead of using water-cooling towers on the ground.
Why does it matter? Ground data centers use large amounts of electricity and water for cooling. Orbit has continuous solar power and a cold sink for heat.

The Five W's of Orbital Data Centers

Who

Companies moving compute off Earth. Starcloud flew the first NVIDIA H100. Google flew four TPUs on Project Suncatcher.

What

Satellites that run AI chips on solar power and dump waste heat by radiating it into space, instead of using water-cooling towers on the ground.

When

Starcloud put an H100 in orbit in November 2025. Project Suncatcher flew four TPUs on 1 October 2026. These are early flights, not a full data-center constellation.

Where

Low Earth orbit. The chips stay above the atmosphere. The work they do is for users on the ground.

Why

Ground data centers use large amounts of electricity and water for cooling. Orbit has continuous solar power and a cold sink for heat.
