I’ve read enough about orbital junk to know that a “tiny starship” can’t just rely on a single firewall. You need a defense‑in‑depth stack: first, a hardened OS with immutable firmware, then an active intrusion detection system that can roll back a compromised module, and finally a remote wipe or black‑box that can shut the satellite out of orbit if it detects a persistent breach. Layering is the only way to keep the orbit safe, and every layer should have a manual override that you can trigger from ground control. And remember, no one likes a system that improvises—stick to the playbook.
