## AI 摘要

Google 的 Project Suncatcher 将 TPU 送入太空测试，搭载 SpaceX Transporter-18 拼车任务，与 Planet 合作建造原型卫星。计划 2027 年发射 2 颗卫星，用激光链路协同运行 AI 负载，实验室系统已实现单向 800Gbps 的激光通信速率。

## 正文

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.
