Comment on Realistically, what do people plan to do on the Moon and Mars that requires a permanent, or long term human presence there?

To your point 5, one of the biggest problem in space is cooling heat producing systems. There are 3 ways of heat transfer:

  1. Conduction - through contact of heat conducting systems like metals.
  2. Convection - through movement of heat transfer fluids like water or air.
  3. Radiation - through infrared radiation.

In space there is only radiative method available which is very inefficient. The moon getting cold on the dark side is due to it lacking atmosphere to hold the heat. One of the reason convection method of heat transfer not available.

Particle collider uses liquid helium to keep superconducting magnets on. Also to cool the collider.

Cooling would absolutely not work on moon. Low gravity may give different results of particle experiment and might be helpful.
