Google 的 Project Suncatcher 计划把 4 颗 TPU 送入轨道，搭载 SpaceX 的 Transporter-18 拼车任务，原型卫星与 Planet 合作建造。Google 下一步计划在 2027 年发射 2 颗卫星，通过激光链路让它们像一台数据中心一样协同运行 AI 负载，其实验室系统已实现每向 800Gbps 传输。
Google 公布 TPU 入轨计划的时间表与激光互联带宽数字，读者可据此了解太空数据中心的工程路径。
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.

Can our TPUs survive and operate in space? Well, we're going to find out. Project Suncatcher is hitching a ride aboard @SpaceX's Transporter-18 mission, testing a prototype satellite built in partnership with @planet One small step for TPUs.... https://t.co/FuZoj7c0Hl在 X 查看被引用的帖子
