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

The moon has HUGE reserves of Helium 3. Earth has almost none and is quickly running out. This is due to the fact that much of those reserves come from the solar wind and Earth’s magnetic field deflects that.
It’s fairly easy to launch rockets from the lunar surface, and comparatively easy to launch things to the Moon vs. Directly from Earth to Deep space.

3a. The moon blocks much of the radio chatter from Earth (on it’s far side) meaning radio telemetry and astronomy have a MUCH easier time doing research

b. By using such methods in concert with Terrestrial installations/telescopes, it makes for a FINE “natural” interferometer for literal logarithmic fractions of the price over Conventional Lagrange point based systems.

The moon is ideal for biological “life boating” (google the “Svalbard Seed Bank” to get what I’m talking about)
Earth’s gravity can sometimes skew the results of VERY sensitive nuclear particle experiments. A particle collider on the moon might lead to exciting discoveries in quantum physics. Also such colliders require lots of liquid helium for cooling. (see point 1) The moon gets INCREDIBLY cold on it’s night side, which saves on energy costs to boot, and night on the moon lasts for 2 weeks.
The Lunar crusts’ composition is almost identical to Earth’s which means it probably has huge reserves of lithium, gold, platinum, titanium, and palladium. The fact that it gets seeded by meteorites frequently also increases these odds.

start with speculation and work your way up. we assume it does, but this has not been proven. please, if I’m wrong, let me know.

Earth has 40 billion cubic metres, that we know of. We won’t run out if we don’t waste it on stupid shit like toy balloons.

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

Conduction - through contact of heat conducting systems like metals.

Convection - through movement of heat transfer fluids like water or air.

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.

  But on the moon you’d also have conductive, and be able to connect directly to a massive heat sink
