SpaceX and rivals file orbital AI data centre plans involving up to a million satellites
SpaceX filed a proposal for one million four‑tonne satellites that it describes as the first step toward a Kardashev II‑level civilization. The United States Federal Communications Commission echoed that language in its filing. Within weeks, four other U.S. firms submitted similar plans: Blue Origin for 51,600 satellites, Starcloud for 88,000, Cowboy Space for 20,000, and Orbital Compute for…
Key points
- SpaceX proposed one million four‑tonne satellites for an orbital AI data centre, citing a Kardashev II goal.
- Blue Origin, Starcloud, Cowboy Space and Orbital Compute filed plans for 51,600; 88,000; 20,000; and 100,000 satellites respectively.
- SpaceX says up to five per cent of satellite mass could survive re‑entry, meaning 500 satellites might drop 400 pounds of debris each over five years.
Aerospace experts say the concepts are detached from practical reality and raise serious safety, atmospheric and light‑pollution concerns. SpaceX’s existing Starlink fleet of more than 11,000 satellites, operating on five‑year lifetimes, already sees one or two car‑sized units re‑enter each day, with a 0.05 per cent survival rate that produced a single piece found on a Saskatchewan farm in 2024. If the million‑satellite constellation shares that rate, about 500 satellites could drop debris on Earth every five years. SpaceX told the New York Times that up to five per cent of a satellite’s mass might survive re‑entry, implying 500 satellites could each shed roughly 400 pounds of material over the same period.
Corporate ‘orbital data centre’ proposals are dangerous for humanity
