Google Project Suncatcher：拟发射4颗TPU卫星组网
Epic moment indeed. Google's "Project Suncatcher" .
算力硬件与AI基础设施的重大跨界创新，太空TPU集群概念极具前瞻性，值得关注其工程落地进展。
Epic moment indeed. Google's "Project Suncatcher" .
确实是史诗级时刻。谷歌的“捕日计划”（Project Suncatcher）。
we’re about to watch AI compute leave the planet earth.
我们即将见证 AI 算力冲出地球。
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.
谷歌即将把 4 块 TPU 送入轨道。SpaceX 是发射服务商，计划搭乘 SpaceX 的 Transporter-18 拼车任务飞行。
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.
谷歌的下一步是在 2027 年发射 2 颗卫星，并通过激光链路让它们协同运行 AI，因为分布式 AI 工作负载需要数据中心级别的带宽。
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.
因此，一组卫星网络需要在太空中像巨型数据中心一样运作。 它们将使用激光束直接在彼此之间传输数据，本质上就是没有线缆的光纤通信。
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.
如果多颗卫星要像一台数据中心那样协同工作，这种速度至关重要，而谷歌实验室系统已达到每方向 800Gbps 的速度。
