【建筑建材】SpaceX计划部署百万颗算力卫星，商业航天需求空间再度扩容——低轨卫星行业跟踪点评（二）（孙伟风/鲁俊）

Core Viewpoint - SpaceX is planning to deploy up to 1 million AI satellites to create a space-based data center, aiming to provide large-scale AI inference and data center services globally [4][5]. Group 1: SpaceX's Satellite Deployment Plan - The core objective of this large-scale plan is to establish a new "space-based computing network" that utilizes solar energy and the unique environment of space to handle high-intensity computing tasks, overcoming the energy costs and physical limitations faced by terrestrial data centers [5]. - The satellites will be distributed across three orbital layers at altitudes of 500 km, 1000 km, and 2000 km, targeting billions of users worldwide [4]. Group 2: Cost Reduction and Launch Capabilities - SpaceX has reduced the cost of launching payloads to approximately $1,400 to $2,000 per kilogram through the regular recovery and reuse of Falcon 9 rocket boosters, with plans to further lower this cost to $100 per kilogram or less with the next-generation fully reusable Starship [6]. Group 3: Communication Infrastructure - Inter-satellite laser communication is the key communication method for SpaceX's orbital data center system, responsible for major data transmission and network routing tasks, ultimately forming a laser network connected to the existing Starlink [7]. Group 4: Potential Asset Integration - Elon Musk is considering the possibility of merging SpaceX with his AI company xAI or Tesla, which could enhance the computing power for xAI through SpaceX's orbital data centers and leverage Tesla's energy storage capabilities to operate these centers using solar energy [9].
