Screw the moon I'm going for Mars.

>>9207994
FUCK MARS WE'RE GOING TO THE SUN, HOP IN NIGGA

Is there anything actually useful on the moon? Coal, precious metals, anything like that? I thought it was all just gray rock.

>>9207999
sunlight

>>9207962
got money for the ticket?

for the mars atleast musk said you have to pay about.. what was it... 100k or so. price of a house roughly. so i'm out!

>>9208002
>cover half the moon in solar panels
I could get behind this.
But how do we transport the power back to earth? Giant batteries?

>>9208019
I'm just regurgitating popsci i see on Facebook tbqh

>>9207999
The Moon has lots of space for Solar Power generation and can also be mined for very rare resources worth lots of $$$.

>>9208005
I want to work there not live. I'm sure most companies will set up shop on Moon and Mars and start industrialising it, they will pretty much cover the transport of its workers. SpaceX has stated it's only a Transportation company at the end of the day and has no interest in off world activities.

>>9207962
I'm going to move to the Moon to work remotely for a company back on Terra

>>9207962
Moon has HE3

>>9208022
interesting! in that case, instead of being rich in money you should be rich in koalafications.

>>9207962
Depends. Can I work from home?

me.
though i dont think aerospace eng will help me in that regard, I don't think ill be designing any spacecraft when im off planet.

what are some skills that will be needed by a mars / moon colony, /sci/? I'm planning on getting a pilot's license anyway.

Best to think of the moon as a small planet without an atmosphere, because that's what it is.

It has all the features of what you'd expect of a planet, including rare elements for new wonder batteries and appliances everyone uses now.

Colonizing the moon is nowhere near to the next several decades. Maybe after 100-150 years yes, but otherwise all the hype for those moon and/or Mars projects is nothing but a marketing bullshit for funding space exploration projects where 80% of the money goes into the pocket of people like Musk.

There is a load of resources on the moon.

>solar energy that can be used 24/7
>moon has a bunch of other rare minerals, if we start mining the helium we will also be learning how to extract all those materials


the moon already has the potential for big $$$ and companies know that, Elon doesnt want to because he is more concerned with sci fi dreams and not the immediate financial gain, but other companies realise that even just having control of an active helium mine on the moon would be worth it for the profit.

then once the tech gets really cheap after all the competition from companies, tourism on the moon will be extremely lucrative, and so will basically all other industries, its like when the europeans first discovered africa or when the pioneers in america began to move west.

the initial barrier seems insurmountable, but for those who go, a literal fortune is ahead.

Mostly just mining but it has other applications, the low gravity and atmosphere make mining, scientific research and functionality as a launch base very achievable.

We will probably see a lot of geologists (selenologists?) in the beginning. After all there has only once been a geologist on the Moon and that was in the very last mission.

Below the regolith surface, the moon is incredibly similar in composition to the Earth.

That being said, so long as we still have the resources on Earth it will always be cheaper to mine them here than to mine them from the moon to be sent here. So things like coal, precious metals, would all be ignored so long as they still exist on Earth.

>>9208268
Skills needed by a colony? Pushing buttons mostly. Oh and the ability to keep your self entertained with the bare essentials

>>9208623
>> mining the moon for helium
Oh fuck no.
>> mining the moon for helium that isn't going to be used for nuclear fusion fuel
I have never seen this level of retardation.

Helium on the moon is present in ppm concentrations, meaning you have to process millions of tons of regolith just to get tiny amounts of helium. It makes sense if you are using the helium for fusion because these tiny amounts of helium would be useful, but not for industrial usage of helium. I'll argue your other points later, but this is by far the dumbest one.

>>9207962
>> What kind of jobs can we expect?
Pushing buttons here on Earth to control robots on the Moon. No humans are going to work on the Moon.

>>9210911
At what point in that post did it say "Helium for industrial use", specifically
why don't you stop being a shitposting ass bandit for once

>>9210957
>nigger detected

>>9210957
>>>used in MRI's and bunches of other important devices like fiber optics
There.

An MRI machine needs something like 2000 liters of liquid helium, which is about 282 kg. Lunar regolith contains 28 ppm of helium, so you'd need to process on the order of 10,000 tons of regolith to get enough helium for a single MRI machine

>>9210555
>Below the regolith surface, the moon is incredibly similar in composition to the Earth.
Do we really have samples from deep under the surface? I never heard core drilling was done.

>>9208037
Don't fall for the helium 3 meme dude, we can't even achieve sustained deuterium-tritium fusion yet, helium 3 fusion is about an order of magnitude harder if not more.

>>9211235

He was wrong, even the regolith layer of the Moon is very similar to the composition of the Earth. Everything's covered in alumina dust though so it doesn't look like it.

No one will go to the moon unless they're as qualified as an astronaut

>>9211356
Isn't that unexpected? The larger gravity and molten core of Earth meant that gold was lost to the depth of the mantle. The Moon has far less gravity and a tiny core. Wouldn't that mean there would be more heavy metals such as gold on the Moon?

To the contrary: you transmit easily convertible microwaves and waste heat is kept out and dumped into space. With a gas or coal fired thermal power station you end up with 2/3 of the energy dumped as heat.

I thought building on the moon was a pretty bad idea because it's constantly bombarded by space dust without an atmosphere to protect the surface

>>9213715
All energy is heat you wanker

>>9214004
Bullshit. The potential energy of water stored uphill in a dam is not heat.

call me dumb, but over time, say maybe 100 years of constant extraction of the moon and mining and removing shit from it’s surface and underneath it, won’t that alter it’s orbit of the Earth since it has less mass?

>>9214100
>100 years
Nope, not enough time.

>>9214220
that's quitter talk

>>9214496
Only mining for 100 years is the quitter talk

>>9214100
we would mine Helium-3, which is ridiculously light, plus we wouldnt even need it in that large quantities. So no.

>>9214835
Heleum 3 is a meme and a bad one at that.

The moon is useful because you can build a mass driver on it. You can shoot your shit into orbit or even to a direct entry trajectory. Shipping shit off the moon is far far cheaper than shipping it off earth. So it will be great for mars and belt and orbital construction.

The moon has cold traps that accumulate water, other volitiels, silver, gold and mercury. The moon has impact sites of platinum group rich asteroids that can be mined. The moon has an abundance of aluminum and titanium, its actually easier to refine them there (in a vacuum) than it is on earth.

The far side of the moon has some of the cleanest radio reception in the solar system because it's blocked by all the noise earth puts out. Would be the best place this side of the oort cloud to build a radio observatory.

I hope humanity has the foresight to leave the side of the Moon facing Earth alone, preserving the view humanity has been fortunate to enjoy since man first looked to the sky in curiosity. Or, maybe a neon "Drink Coke" sign, as proof of man's intelligence.

>>9207962
Why the fuck would I give up my comfy life on earth to go live in a 2x4 tin can on the moon? Anyone who would be so glib about doing something as radical as that should be automatically excluded from space travel.

>>9215123
Power density of the beam is too low to do this. So you'd have to collect the beam with microwave to electricity converters(a so called rectenna) transmit that electricity to your house and then turn it back into microwaves

>>9215129
it was a joke but thanks for the explanation.

>>9214870
>Heleum 3 is a meme and a bad one at that.
Citation needed.

Fusion is not yet mastered but nobody will take their chances and leave He3 resources to another country to dominate this resource. And there are 2 important historical incidents people unlike you will learn from
- the US buying Alaska from Russia, widely considered by opinionators to be a dumb move. Then oil became important
- China dominating rare earth metals due to short sightedness in the West about closing strategically important mines.

They will not make that mistake again.

Fuck sending it here. Build space ships on the moon without the huge fucking launch costs of earth.
You could build vehicles almost unconstrained in size and weight since launching from the moon is so fucking easy.

>>9207999
it has the same elemental composition as the earth, and a permanent moon colony would mostly be useful for space exploration, since it's much, much cheaper to send things in to space from the moon than from earth.
Downside is the fact that moon dust is truly awful, horrible stuff that will ruin everything. Wheeled vehicles may end up being completely non-viable there. That moon dust will fuck up any exposed axle. We might have to move around using mechs up there, since the joints of mechs could be much more easily sealed with coverings to keep out the dust.

>>9208020
You just power Bitcoin miners on the moon and beam back solved blocks, dumbass

>>9221047
>Wheeled vehicles may end up being completely non-viable there.

>>9221047
In what world are complex joints easier to seal than rotating axles, you mong?

>>9207999
cheese

>>9207999
The Moon has the same composition as Earth, since the Moon was (at one time) part of Earth.

The lower gravity would make the Moon an excellent place for launching craft.

>>9210555
>so long as we still have the resources on Earth it will always be cheaper to mine them here than to mine them from the moon to be sent here
Problem with this attitude, is that it makes it highly unlikely we'll ever leave Earth or develop a space-based economy, because its simply cheaper to stick with the status quo.

That's true. You know how helium gets there? From solar wind. You don't get solar wind anywhere but the surface.

>>9207999
Helium-3, man.
Shitloads of it, and fusion works best when you've got helium-3. Sure, we need to figure out fusion first, but once we've done that the moon will be our primary source of energy

Also 3 digits for helium-3.

>>9227810
yeah but keep in mind of collisions, and how all the rocky planets have radioactive elements that release alpha particles (He4) its how earth got its helium, and the moon has been shown to have a litterally nearly identical composition as earth (from asteroid and dust samples) this means
>it was either formed from a crash between earth and an early proto Planet, in which case, it would have radioactive elements, and helium
>or, that it was formed in another way, hut still from the same stuff that our solar system is made out of, in which case, it has radioactive elements, and helium


either way, helium pockets are mostly just a natural decay of radioactice elements, so there are pockets of helium underground
