How hard is it to build orbital data centers, actually?
摘要
SpaceX计划建设由100万颗卫星组成的轨道数据中心星座，可产生120 GW电力，支持数千万至1亿个前沿级GPU运行。该公司已公布首代AI1卫星的尺寸和功率参数，但具体技术细节仍在开发中。
SpaceX has pinned the bulk of its future value on orbital data centers. Not rockets. Not spacecraft.
Instead, it envisions launching and maintaining a constellation of 1 million satellites capable of generating 120 GW to power tens of millions—and potentially up to 100 million—frontier-class GPUs for data center services.
The company's founder, Elon Musk, revealed plans for this massive constellation months ago, but until recently, the scope of the individual satellites was largely unknown. That changed in June, when Musk and Ian Dahl, director of satellite engineering for SpaceX, spoke in a promotional video about the company's plans to develop the first iteration of an orbital data center, called an AI1 satellite. The video finally provided the company's numbers about the satellite's size and power capabilities.
