I spot motion in the corner of the screen. An irregular-shaped object slides along a track in the hull. It’s a stalk sticking up with five articulated “arms” coming out of the top. Each arm has a clamp-like “hand” on the end.
It’s only now that I notice a network of the tracks all along the hull.
It’s a robot. Something controlled from the inside. At least, I assume it is. It doesn’t look like a little green man, and it certainly doesn’t look like an alien EVA suit.
