OCaml Reaches Orbit: Functional Language Powers Secure Satellite Operations

A pure-OCaml CCSDS protocol stack has successfully launched to low Earth orbit, validating OCaml 5's potential for safety-critical space systems. This deployment proves that functional languages can deliver C-level performance while maintaining memory safety in untrusted environments—a crucial advantage when multiple tenants share expensive satellite hardware. The achievement vindicates KC Sivaramakrishnan's 2022 prediction that OCaml 5 would eventually reach the moon.
