Warning- Portal 2 spoilers
Does nobody on the face of the Earth realize Weatley and the Space Core should have come crashing down with the rest of all the debris from the facility since the air rushing out of the portal wasn't going at Lunar escape velocity? There's no way Chell would have survived winds going several kilometers a second.
You could argue that the shots of Weatley and the Space Core were taken sometime during either their ascent or decent (and yes, it probably would have taken quite a while for them to come crashing down as they were going really fast) but my guess is that nobody bothered to consider all this. Especially considering the two videos of Weatley shown at the Spike Game Awards.
That would have been the perfect ending shot- Weatley and the Space Core each broken in a thousand pieces in the middle of a pile of debris at the Lunar Landing site. There would be no question he's gone for good.
Edit: Cool picture, btw. You should try doing an isometric version (or a perspective version!).
The game can violate conservation of energy, makes portals, jumpy and runny goop, force fields made of light and swirling tractor beams and you're complaining about THAT?
