Google 首颗数据中心卫星上线，搭载 TPU 与 Gemma 4 写诗
原标题：Google’s first data center satellite is online and writing poetry
AI 摘要
Google 的 Suncatcher 太空数据中心原型卫星已上线并与地面通信，该卫星搭载一颗 TPU、发电功率最高 1 kW，并预载了 Google DeepMind 的 Gemma 4 模型，首次提示词要求其写一首关于太空的俳句。由于 TPU 功耗限制，它每次只能开机约二十分钟，增加了天地通信难度。后续测试将评估芯片在热应力和太空辐射环境下的表现；若验证成功，Google 计划 2027 年再发射两颗搭载先进芯片的卫星，并演示星间光链路。

Google Suncatcher’s prototype space data center is online and communicating with the ground after launching earlier this month alongside more than 100 other spacecraft on a SpaceX Falcon 9 rocket. The satellite, which carries a single Google Tensor Processing Unit (TPU) and generates up to 1 kW of electricity, is intended to pave the way for future networks of close-flying satellites performing large inference workloads in orbit. However, the power demands of the TPU mean it can only turn on for
