Its hard to think of much you might have missed. Most of what I've got is dependent on the setting the GM chooses.

• Terra-forming Unit
• Nuclear Reactor
• Library/Game Room (holodeck?)
• Escape Pod
• Rocket booster (getting back to the station)
• Assorted Construction Machinery
• Rampant AI (Managing ship and ascending to deity status)

Your active detector entry should read signals emitted by the unit, not submitted.

There is a fine line between hobby and obsession. I seem to have lost sight of it some time ago.
