I haven't seen any documentation on it. [ Jim keeps moving as they speak, looking down corridors, checking in rooms. ] Given the fact that the stasis room is on its own circuit, and they've employed heavy duty holograms up here before, it may be a mix of tech like we see dirtside. Heavily 'magic' with radio and electricity integrated in portions. If it were a warp core reactor I'd be able to hear it, probably, or--

[ Jim stops, makes a thoughtful noise, and then quiets as he waits with a hand on the nearest bulkhead. Listening, feeling. He understands spacecraft in a way most people, even most space travelers, don't. He's not at Scotty's level, but he's got an uncanny intuition. He just needs to get to know Thesa, maybe. ]

Mm. [ He shrugs. ] They've gotta have intermittent propulsion to keep from dropping orbit and they've got to have a reactor to keep life support going. Doubt it's nuclear. Someone would have noticed the maintenance.
