Google Project Suncatcher 原型卫星入轨，测试 TPU 太空运行
Project Suncatcher has liftoff! ☀️🚀
Google 的 Project Suncatcher 已将一颗原型卫星送入轨道，搭载于 SpaceX Transporter-18 拼车任务，卫星由 Google 与 Planet 合作建造。该任务将收集 Google TPU 在太空飞行物理压力与极端环境下的表现数据，为未来连接多卫星星座进行规模化机器学习探索铺路。在低地球轨道运行可获取近乎持续的阳光，太阳能发电量最高可达地球上的 8 倍。

Project Suncatcher has liftoff! ☀️🚀
Announced last year, this moonshot project explores if we can one day host machine learning infrastructure in space. After years of research, we’ve just launched a prototype satellite, built in partnership with @planet, into orbit on @SpaceX's Transporter-18 rideshare mission.
This initial mission will gather data on how @Google TPUs handle the physical stress and extremes of spaceflight. Ultimately, these findings will help us explore how to potentially link multiple satellite constellations for scaled machine learning. By operating in low Earth orbit, these systems can tap into near-constant sunlight to generate up to 8x more solar power than on Earth.
