1. **背景与动因**:AI与数字基础设施需求激增,地球数据中心面临土地(NIMBY效应)、能源(2030年需求近1000TWh)、水资源及碳排放(2025年美国超100Mt CO₂)压力,推动计算向空间迁移。 2. **核心优势**:空间数据中心可缓解地球资源约束,利用近连续太阳能、无水辐射冷却,规避地方法规限制,运营期零碳排放。 3. **成本现状**:当前1GW空间数据中心5年总成本约460亿美元,是地球数据中心(170亿美元)的近3倍,主要源于卫星制造与发射成本。 4. **关键挑战**:需突破冷却技术、辐射硬化硬件、在轨维护等瓶颈;经济性依赖发射成本(目标降至150美元/kg)及卫星规模化制造。 5. **应用前景**:国防、地球观测为近期可行场景;AI训练需长期技术迭代,未来依赖可重复发射、自主机器人等突破。
