Why is there a black patch on the back of the rover?

I'm not sure which patch you're talking about. Maybe it's labelled in one of these images?

I assume that this is where the connection between the camera and the rover is (a robot arm or the like), and which thus cannot be photographed.

Glitch in this pano, it's fine in this version: http://www.360pano.eu/show/?id=731

It does almost look like something was edited out. Not sure though.

It might be missing image data (not sent / not photographed yet).
