谷歌发射首颗TPU卫星，称星舰需发射1600次才能支撑太空数据中心
原标题：Google thinks SpaceX’s Starship has to launch 1,600 times before space data centers get off the ground
AI 摘要
谷歌通过SpaceX火箭将首颗搭载TPU的轨道计算卫星送入太空，用于验证其AI芯片在太空环境中的运行能力，这是Project Suncatcher计划的第一步。谷歌同时发布了关于轨道数据中心的同行评审白皮书，认为SpaceX需在10年内完成约1800次星舰发射、将发射成本降至每公斤200美元左右，轨道数据中心才具备经济可行性。测试显示TPU可承受太空辐射，适合在轨推理，但大规模训练仍面临挑战。

Google’s prototype of its orbital compute satellite took off today onboard a SpaceX rocket launched from California — the first time the tech giant has sent one of its advanced chips into space. Built by Planet Labs, the satellite will prove that a Google Tensor Processing Unit, its competitor to Nvidia’s GPUs, can function in space. That means supplying a kilowatt of continuous power, cooling the chip, and running a series of models through their paces to see if anything goes wrong. “We’ve done
