Google's Project Suncatcher to test Trillium TPUs in orbit on Transporter‑18
Google will launch a prototype satellite for Project Suncatcher on SpaceX’s Transporter‑18 rideshare to collect in‑orbit data on how its Trillium TPUs handle launch vibration, radiation, thermal vacuum, and cooling. Ground tests (vibration, thermal vacuum, and proton‑beam radiation tests at UC Davis) showed promising resilience, and the mission will inform designs for cooling, radiation mitigation, and high‑bandwidth laser links ahead of a planned 2027 two‑satellite test.
