Elon Musk is truly ambitious. SpaceX has just submitted a groundbreaking plan to the Federal Communications Commission (FCC): the company is applying to deploy up to 1 million satellites to establish an unprecedented "Orbital Data Center" system in Earth's orbit. This project not only far exceeds the current Starlink network (approximately 9,600 satellites) in scale but also symbolizes SpaceX's ambition to transform into a global computing platform. In the application, SpaceX explicitly states that this system will possess "unprecedented computing power," designed to drive advanced artificial intelligence (AI) models and their global applications. The core idea is to address two major bottlenecks faced by ground data centers: energy consumption and cooling costs. - Environmental Advantages: Orbital data centers can directly utilize high-efficiency solar power from outer space and leverage the low-temperature environment of space for cooling, avoiding the massive demands for electricity, land, and water resources on the ground. - Technology Integration: These data satellites will be deployed at orbital altitudes of 500 to 2,000 kilometers, connected via "laser optical links" with the existing Starlink network, enabling rapid data return to ground-based end users. Industry analysts point out that SpaceX's bold "million-satellite" concept relies on the maturity of its flagship rocket, Starship. Starship features enormous payload capacity and full reusability, significantly reducing satellite deployment costs. At the same time, this grand expansion plan is closely related to recent IPO rumors about SpaceX. Market whispers suggest that SpaceX is in talks with Wall Street banks and is expected to go public by mid-2026, with a valuation potentially reaching $1.5 trillion. This funding is anticipated to be the main driver supporting the orbital data center project. Despite the ambitious scope, the scale of 1 million satellites has raised serious concerns about space environment impacts. The FCC has historically been cautious about SpaceX's satellite applications; earlier this month, it approved the application for 7,500 second-generation Starlink satellites but has not yet approved the remaining nearly 15,000 requests. Additionally, issues such as "orbital congestion" and "space debris" caused by such a large number of satellites will face strict scrutiny from international astronomical and environmental organizations. Although SpaceX has launched collision monitoring systems like "Stargaze" to reduce risks, convincing regulators to approve a million satellites remains a key challenge for the future.
