You sneak onto an armed frigate while it is hovering near the asteroids. You fight through to the bridge when your plan falls apart. It takes an entire crew to operate this vehicle. You have two options: Set the ship to destroy itself and fall into the sun, or dump its entire multi-million dollar load of ores into space where Nyi-Zog can send scavengers to collect it. The latter takes quite a bit longer than the former. Perhaps it is time to cut your losses and leave.
