Google Launches Orbital Compute Satellite with SpaceX, Eyes Future Space Data Centers
Google has launched its first orbital compute satellite aboard a SpaceX rocket from California. The mission tests whether Google's Tensor Processing Unit (TPU) can function in space under real conditions after ground-based simulations. This marks the beginning of Project Suncatcher, an initiative to develop large-scale computing clusters in orbit for future AI and data processing needs. The current satellite is a prototype built by Planet Labs that will test TPU performance through 15-minute bursts to avoid overloading its power systems. Google plans more advanced satellites next year with laser communication links between them. The company envisions a network of up to 81 satellites working in parallel, but acknowledges the need for cheaper and scalable rocket launches before such infrastructure can be realized. Google's research suggests that SpaceX must launch Starship approximately 1,600 times over ten years—about 180 per year—to reduce costs enough for orbital data centers to become feasible. The company also released a peer-reviewed white paper on the topic in Joule, highlighting its long-term vision and reliance on SpaceX's cost-reduction trajectory.
