I cited the times to illustrate the periodicity of the thermal cycle.
Sorry if that wasn't clear.
Listen, we can go on about this but my feeling is this. If the intent is to have a manned civilian moon base, I'm for it assuming it doesn't sap the rest of space science for flags and footprints. Now, assuming this infrastructure exists and is manned fairly constantly, why not set up a robotically controlled scope that could be maintained by the crew. That's it.
All the other issues are engineering problems and would be solved in due course.
