Progress in quantum computing is accelerating, with several nations striving to build the first machines capable of breaking today's encryption standards.
These advances have direct consequences for the commercial space industry, as many satellites and ground systems rely on encrypted links for data transmission.
If quantum computers defeat current cryptography, sensitive information flowing between satellites and ground stations could be intercepted.
Experts warn that this could create new national‑security risks in orbit, especially for military and governmental spacecraft.
In response, work on quantum‑resistant encryption is being accelerated, and some satellite operators are already testing hybrid protection schemes.
