Why SpaceX Seeks Approval to Launch 1 Million Satellites: Key Insights

As 2026 approaches, one of the year’s most significant space stories is already emerging: the rise of mega-constellations and ambitious plans to launch thousands of satellites into Earth’s orbit.

Recently, SpaceX made headlines by requesting approval from the US Federal Communications Commission (FCC) to deploy 1 million orbital data center satellites. This unprecedented move follows SpaceX’s previous filing in 2019 for 42,000 Starlink satellites.

“This is an unprecedented scale for any satellite constellation,” says Victoria Samson, an expert at the Secure World Foundation in the United States.

Currently, SpaceX operates the largest satellite constellation, the Starlink Internet service, with approximately 9,500 satellites in orbit of the total 14,500 satellites. However, this current setup represents just 1% of SpaceX’s planned satellite network. Furthermore, these Starlink satellites are already navigating a risky orbit, as the company anticipates needing to prevent 300,000 collision scenarios by 2025.

The latest information released on January 30 reveals CEO Elon Musk’s vision for these data centers. Musk states that the launch of a million satellites is a fundamental step towards evolving into a Kardashev II civilization. The Kardashev Scale, developed by Soviet astronomer Nikolai Kardashev in 1964, quantifies the technological advancement of civilizations.

With AI’s energy requirements rising, the concept of space-based data centers has gained traction. In November 2025, the American company StarCloud successfully launched a demonstration data center powered by advanced Nvidia chips. The European Commission has also conducted studies indicating the feasibility of such orbital data centers.

Musk suggests that the reusability of SpaceX’s Starship rocket, the most powerful rocket ever built, enables this ambitious satellite deployment. He claims, “With hourly launches and 200 tons per flight, Starship will transport millions of tons yearly into orbit and beyond, ushering in a new era of human exploration.”

This filing coincides with SpaceX’s announcement on February 2 about acquiring xAI, a company that operates the social media platform X and the intriguing Grok chatbot. “If you want AI in an orbital data center, it’s a bundled package,” says Ruth Pritchard-Kelly, a US satellite regulation expert.

SpaceX is not the only entity aiming to launch more satellites. On December 29, China requested to the International Telecommunication Union (ITU) to deploy 200,000 satellites into space. While there are no explicit restrictions on the number of satellites that can be safely deployed, prior research has suggested that managing over 100,000 satellites could become exceedingly challenging.

The FCC will take several months to decide on SpaceX’s application, during which public comments are welcome, and a separate submission to the ITU is required. Once approval is granted, SpaceX typically has six years to deploy half of the constellations but is requesting a waiver, arguing that their satellites communicate via optical links and do not cause radio interference.

SpaceX has stated that it will place its satellites in slightly polar orbits, ranging from 500 kilometers to 2,000 kilometers in altitude, primarily above the current Starlink operational altitudes. While the dimensions of the proposed satellites remain unspecified, it’s estimated that if they are similar to existing Starlink satellites, approximately 10,000 Starship launches will be needed to complete the constellation.

If Musk’s plan for hourly launches is realized, it would take just over a year to deploy the entire million satellite network. SpaceX assures safe disposal of satellites at the end of their operational lifespan by relocating them to decommissioned orbits or placing them in solar orbit.

The extensive proposed constellation could significantly impact astronomical research. SpaceX highlighted its ongoing collaboration with the scientific community in its application. However, in December, researcher Alejandro Borlaf from NASA Ames Research Center warned that adding 500,000 satellites could render “nearly all telescope images from the ground and space contaminated by satellites,” hampering scientific discovery.

These orbital data centers might be brighter than many existing satellites due to their need for large solar panels and radiators similar to those found on the International Space Station, designed to expel heat into space.

Whether or not SpaceX is genuinely prepared to deploy 1 million satellites remains uncertain. Given the staggering nature of this number, Pritchard-Kelly suggested this could be an instance of Musk’s “shock and awe” tactics, implying that the actual satellite count may be significantly lower. SpaceX and the FCC have not responded to requests for comments.
