埃隆·马斯克提议建造一个由100万颗卫星组成的人工智能数据中心星座1。根据SpaceX向美国联邦通信委员会提交的提案，这一计划将产生严重的太空电子废弃物问题1。
由于数据中心GPU的预期寿命约为五年1，每年需要有约20万颗卫星退役1。对这些报废卫星的处理方式凸显了该方案的环境风险：约4万颗卫星将坠落大气层燃烧，剩余约16万颗卫星则被送入远地轨道弃置1。被送往远地轨道的卫星材料将永久流失于地球物质循环之外1。此外，卫星在大气层燃烧过程中释放的铝等物质可能导致"未知程度的臭氧层耗损"1。
SpaceX has proposed constructing an artificial intelligence data center constellation consisting of one million satellites in orbit, according to a filing submitted to the FCC on May 29 1. The ambitious plan raises significant concerns about space debris and environmental impact, as the infrastructure would generate substantial electronic waste throughout its operational lifetime.
Under SpaceX's proposal, approximately 200,000 satellites would require retirement annually, driven by the roughly five-year lifespan of data center GPUs 1. Of these decommissioned satellites, about 40,000 would be directed to burn up upon reentry into the atmosphere, while the remaining 160,000 would be relocated to distant orbits and abandoned 1. This disposal strategy presents a novel environmental challenge: materials permanently removed from Earth's material cycles and substances released through atmospheric reentry, including aluminum from satellite combustion, could cause unknown levels of ozone layer depletion 1.
