Google’s Project Suncatcher explores building a scalable AI computing system in space using solar-powered satellites with TPUs connected by optical links, aiming to overcome terrestrial resource limits.

Why it matters: Space offers near-continuous solar power, enabling potentially massive AI compute without Earth’s energy constraints.

The big picture: Challenges include ultra-high bandwidth satellite links, precise orbital control, radiation-hardened hardware, and cost-effective launches.

The stakes: Key hurdles like thermal management and reliable on-orbit operation must be solved before space-based AI data centers become feasible.

Commenters say: Enthusiasm for space AI is tempered by skepticism on cooling, cost, practicality, and whether space truly outperforms terrestrial solar data centers.
