Google 发射首颗搭载 4 块 TPU 的测试卫星，验证太空运行 AI 硬件
Google 宣布其登月项目 Project Suncatcher 探索未来在太空中托管机器学习基础设施，上周已发射首颗测试卫星，搭载 4 块 TPU 进入轨道。Google 研究人员过去几年一直在探索 TPU 能否承受太空飞行的物理压力以及太空中的辐射和极端温度。
Project Suncatcher is our moonshot exploring whether we can one day host machine learning infrastructure in space 🚀
To do so, we need to know whether our AI hardware can operate in orbit. Can our TPUs handle the physical stress of spaceflight and the radiation and thermal extremes of space? These are the questions Google researchers have been exploring for the past few years.
Last week, we launched our first test satellite carrying four TPUs into orbit — putting us one step closer to getting answers.
