New ideas I thought of (AKA Things Cribbed from Episodes of Star Trek, Babylon 5, Farscape and Firefly)
4) A highly tense negotiation scene. On planet or ship to ship.
5) Transporting a diplomat, crime boss, or other important figure to a destination. Possible complications are varied, including the NPC having a pecular palette. Perhaps enemy forces, or the threat of enemy forces looking to rescue/capture/kill the NPC.
6) Out of Gas. I don't know how the tech needs to work out, but for some reason the Raider is forced to land and the PCs get into some situation where they either have to defend the Raider, get captured by enemies, or maybe they decide to go out on a small camping trip while the Positronic Storm dissipates.
