Google 推进 Project Suncatcher：把 TPU 送入太空组数据中心
Google 要把 TPU 发上太空，2027 年两颗卫星用 800Gbps 激光链路组网，SpaceX 负责发射，脑洞挺大。
Google 的 Project Suncatcher 计划将 4 颗 TPU 送入轨道，发射由 SpaceX 的 Transporter-18 拼车任务承担。下一步是 2027 年发射 2 颗卫星，让它们协同运行 AI 工作负载。卫星之间用激光链路通信，相当于无线的光纤，Google 实验室系统已实现单向 800Gbps 的传输速率。目标是让一组卫星像太空中的大型数据中心一样运行。
Epic moment indeed. Google's "Project Suncatcher" .
we’re about to watch AI compute leave the planet earth.
Google is about to put 4 TPUs in orbit. SpaceX is the launch provider, and is scheduled to fly on SpaceX's Transporter-18 rideshare mission.
Google's next step is to launch 2 satellites in 2027 and make them run AI together with laser links, because distributed AI workloads need data center class bandwidth.
So a network of satellites need to operate like a giant data center in space. They'll send data directly between each other using laser beams, basically fiber-optic communication without the cable.
That speed is crucial if multiple satellites are going to work like one data center, and Google's lab system has already reached 800Gbps each way.
