Recently, multiple authoritative institutions have stated that ‘space-based computing’—or ‘computing power in space’—has become an industry consensus. This concept refers to deploying computational resources on low-Earth orbit satellites, space stations, or even lunar platforms to build an integrated space-ground computing network. The trend stems from growing constraints on terrestrial computing capacity, increasing demands for ultra-low latency data processing, and the urgent need for edge computing capabilities worldwide.With the rapid advancement of artificial intelligence, the Internet of Things (IoT), and 6G communications, traditional ground-based data centers are facing challenges such as high energy consumption, limited coverage, and latency issues. By placing computing power in near-Earth orbit or higher altitudes, data can be processed closer to its source, enabling real-time analytics in remote areas, over oceans, and during air travel. Moreover, space-based computing can significantly support deep-space exploration and astronomical research.Countries including China and the United States, along with major tech companies, have already launched related initiatives. For instance, China is advancing its ‘Star Computing’ project to test AI chips on low-orbit satellites, while companies like SpaceX and Amazon are developing space-based computing infrastructure. Although challenges remain—such as high costs, technical complexity, and power supply—experts agree that the strategic value and long-term potential of space-based computing are widely recognized, positioning it as a critical component of future global digital infrastructure.
近日，多家权威机构指出，“算力上天”已成为行业共识。所谓“算力上天”，是指将计算资源部署在低轨卫星、空间站甚至月球等太空环境中，以构建天地一体化的算力网络。这一趋势源于地面算力资源日益紧张、数据传输延迟难以满足未来需求，以及全球对边缘计算和实时处理能力的迫切要求。随着人工智能、物联网和6G通信等技术的快速发展，传统地面数据中心面临能耗高、覆盖有限、响应延迟等问题。而将部分算力部署到近地轨道或更高空域，可实现更广范围的数据采集与处理，尤其适用于偏远地区、海洋、航空等场景。此外，太空算力还能为深空探测、天文观测等科研任务提供强大支持。目前，包括中国、美国在内的多个国家和科技企业已启动相关计划。例如，中国正在推进“星算”工程，探索低轨卫星搭载AI芯片；SpaceX、亚马逊等公司也在布局天基计算基础设施。专家认为，尽管“算力上天”仍面临成本高、技术复杂、能源供应等挑战，但其战略价值和长远潜力已获得广泛认可，未来有望成为全球数字基础设施的重要组成部分。
