Project Suncatcher

Google’s Project Suncatcher proposes space-based, solar-powered AI data centres.
It proposes tightly coordinated clusters of satellites, spaced only a few kilometres apart, orbiting in a way that always keeps them in continuous sunlight.
Why is it needed ?  Datacentres consume massive amounts of electricity as AI requires large clusters of energy-intensive processors to train and operate its models.
* Unlike normal datacentres, AI datacentres depend on ultra-fast, high-power internal networks, since most of their work involves machines communicating with each other rather than serving users directly.
Radiation risk: Long-term exposure may damage chips, though tests show some resistance.
Maintenance problem: Repairing or replacing hardware in space is difficult and costly.
Cooling challenge: Heat must be removed in vacuum while facing constant solar exposure.
Economic viability: Launch, replacement, and R&D costs must compete with Earth-based datacentres.
What’s next ? Google is planning to launch two prototype satellites by early 2027 that will test hardware in orbit.
