Google 与 Planet 合作发射搭载四颗 TPU 的卫星，启动 Project Suncatcher 太空机器学习基础设施研究

AI 导读

Google 与 Planet 合作，在 SpaceX Transporter-18 拼车任务上发射一枚搭载四颗 TPU 的原型卫星，这是其长期研究项目 Project Suncatcher 的第一步，探索能否在太空部署可扩展的机器学习基础设施。未来几周团队将收集在轨数据，观察 TPU 如何承受太空中的物理应力、辐射和极端温度，并据此改进未来设计。

Up, up, and away. 🚀

Today, in partnership with @planet, we launched a prototype satellite carrying four TPUs into orbit on @SpaceX's Transporter-18 rideshare mission. This launch is the first step of Project Suncatcher, our long-term research moonshot to see whether we can one day host scalable machine learning infrastructure in space.

Over the coming weeks, we'll gather in-orbit data on how our TPUs handle the physical stress, radiation, and thermal extremes of space. Whatever we learn, we'll use it to refine our future designs.
