- Parsimoni's pure-OCaml CCSDS protocol stack, Borealis, successfully booted in low Earth orbit on April 23, running on DPhi Space's ClusterGate-2 payload module.
- OCaml's safety features are crucial for satellite security, mitigating risks of untrusted code and memory corruption vulnerabilities common in C/C++ systems.
- Borealis implements end-to-end encryption, post-quantum key rotation via OTAR, and uses CCSDS protocols with BPSec for confidentiality and authenticity, ensuring tenant isolation on shared hardware.
- The project leverages OxCaml (Jane Street's OCaml fork) for performance-critical paths, reducing latency and GC pressure, with future plans for fleet-scale deployment and secure software management.
