Google unveils Project Suncatcher to host TPUs in solar‑powered, optical‑linked orbital data centres

Project Suncatcher proposes compact constellations of solar‑powered LEO satellites carrying Google Trillium TPUs, connected by free‑space optical links to run large AI workloads. Trillium chips passed particle‑accelerator radiation tests, but Google warns on‑orbit thermal management and long‑term reliability remain key hurdles.

Sun unleashes two X‑class flares, triggering radio blackouts across the Americas and Pacific Two back‑to‑back X‑class solar flares erupted as active sunspots turned to face Earth, producing radio blackouts across both hemispheres that knocked out shortwave communications across the Americas and much of the Pacific, briefly degrading HF radio links and ionospheric communications.

Hemeria warns French GEO ‘guard‑dog’ satellites unlikely to launch before 2028, delaying on‑orbit protection Hemeria says two small ‘‘guard‑dog’’ satellites intended to operate around France’s larger military GEO assets are unlikely to launch before 2028, postponing the country’s planned on‑orbit protection and inspection capability and extending a capability gap for its geostationary defence satellites.
