Google Launches AI Data Center to Space
27 Sep
Summary
- Google's first orbital data center satellite launches October 1, 2026.
- The satellite carries four custom Tensor Processing Units into orbit.
- TPUs can withstand demanding radiation levels for five-year missions.
Google is set to launch its inaugural experimental orbital data center satellite on October 1, 2026, marking a significant step for its Project Suncatcher initiative. This ambitious research aims to explore the feasibility of hosting scalable machine learning infrastructure in low Earth orbit, primarily powered by solar energy.
The satellite, dubbed MVP, is equipped with four of Google's custom-designed Tensor Processing Units (TPUs) and has undergone extensive testing to ensure its survival in the harsh space environment. Radiation testing at UC Davis demonstrated that the TPUs could endure radiation doses exceeding those expected over a five-year orbital mission.
Engineers also simulated the intense vibration and acceleration forces of a rocket launch, confirming the hardware's resilience. While cooling remains a significant challenge, with current TPUs operating in 15-minute bursts, future designs plan for dozens of chips communicating via laser connections. Google intends to test this constellation communication in 2027.
