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.

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.

  I was referring to that being a supplemental benefit. LiHe cooling would still be the main method, just that having that extra radiative “boost” would help do so with increased efficiency/speed. (even if it’s a small boost)

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

    This, but you can also build a traditional heat sink (panels) and let the fact that it’s very cold do the work for you. yeas it would be radiative and that’s slow, but again, two weeks of night.

uhh. dude, that’s a source?

the ESA link is in no way proof that there’s significant helium 3 reserves on the moon.

“The Apollo programme’s own geologist, Harrison Schmidt, has repeatedly made the argument for Helium-3 mining, whilst Gerald Kulcinski at the University of Wisconsin-Madison is another leading proponent.” ---- this in no way asserts that there’s actually significant amounts of helium 3 recoverable from moon mining, it’s simply stating it’s worth looking into, worth exploring.

we have no idea how much helium 3 has been deposited by solar wind onto the moon’s surface; it could be HUGE. it could be a tiny fraction of a fraction of a percentage. We won’t know until we go look.

Please, when you post links that are supposed to buttress your argument, post something that actually supports what you’re proposing. your premise:

The moon has HUGE reserves of Helium 3

in no way is supported by that link.

  If the ESA (AKA Actual Scientists) thinks it’s worth our time, and you are still not convinced then I literally don’t know what to tell you. Lunar regolith is lose, and lunar crust is generally porous. The moon lacks a magnetosphere and so absorbs the solar wind rather than deflecting it. The Solar wind is mostly charges particles but it’s also filled with Hydrogen fusion byproducts which is mostly HELIUM.
  
  Science is not 100% observable facts, but a good chunk of it is learning to INFER THINGS FROM AVAILABLE DATA SETS.

    what fuckin data sets? is there a link to actual data on that page?

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.

    dude, I replied to your original post, that’s not supporting your premise at all.

Earth has almost none and is quickly running out.

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.
