Colin wants to know:

Is there a region on Mercury or the moon where the temperature is livable? Like in certain craters or a Twilight zone?

Thoughts?

If you were prepared to keep moving, the temperature in the twilight zone might be liveable. But too far into the night or day side, and the temperatures become extreme.

A polar crater might be liveable, if you could reflect some light down into it. But then you lose the main resource of unlit craters - deposits of water ice that can be used as sources of oxygen and rocket fuel.

Regardless of the temperature, the lack of an atmosphere is pretty inhospitable.
