“city” on the Moon

Jokes on the idiots who are gullible enough to invest money into this

The joke is on you. The amount of mineral resources on the moon is astonishing.
Ask the Chinese why they're going to do the same thing?

Neither of them have an atmosphere either and are regularly pelted with space debris. It's all fun and games until a space rock traveling 2000 mph smashes into your biodome like a patriot missle whereas 99% of these asteroids burn up and turn into harmless shooting stars when they mess with the mighty earth and our gaseous force field.

Go on explain why.. i already did. It doesn't take much to Google to even get a rudimentary explanation.

Also with zero gravity easier to launch massive payloads offsite. You can consolidate up there and then launch to mars


SIAP, but: a moon base with mining operations will also help pay for the Mars expedition and colony.

Also, microgravity.

But yeah let’s make Star Trek real life.

How does a city on the moon secure the future of civilization? The earth after a nuclear apocalypse would still be more hospitable than the lunar surface, not to mention have more resources.


Why don’t we just build colonies at the bottom of the sea? Might be easier.

?

The Moon doesn't have zero gravity.

The relative lack of basic scientific and technical knowledge in this thread is alarming.

The large scale AI data centers put out something like 30 megawatts of thermal energy.

That would require a radiator surface area of over a square kilometer to dissipate

I love when ill thought out buzz words are used.

There is no value in mining on the moon for stuff for earth. None. There is value perhaps in getting building materials for space projects, and building it there. But not to send back.

Colonizing the moon and using it as our launchpad into the rest of the solar system was always going to be the path forward.

Yeah this doesn’t seem ripe at all for unintended consequences….

We're going to be debating Bad Bunny down here while there is a US-Sino robot war on the moon

Just a little perspective on distance. I takes about 1.25 seconds for a radio signal to go from the earth to the moon. In contrast, it takes between 3 and 22 minutes for a radio signal to travel from Earth to Mars, depending on their relative positions in orbit around the sun.

Which is Musk is going to have satellite relays between the earth moon and mars all they way through.

This is going to be extremely challenging all the way around but it will lead to technological advances just like the original space program did, actually way beyond.

I think in the 2030s once this is getting closer to reality, they will abandon the concept of humans being there for awhile and it will be Optimus robots and drones doing everything on the moon and then mars, at first.

Just because you watched Moon doesn’t make you knowledgeable about moon mining economics.

Yes, helium-3 is more abundant on the moon than on earth, but it’s still fairly rare. Like 10 parts per billion.

You gotta process a lot of soil just to get a little.


And the primary use case seeing economic advantages would be fusion power, which we are still decades from really getting it figured out as a commercial tech…….and helium-3 fusion takes the existing technical challenges and makes it even worse.

There are some interested parties sticking their toe in the water. But no one is rushing over each other to get there.

Will his satellites have the ability to alter the speed of light?

Riddle me this: What's the fastest path between any two points?

How would that change anything unless we have manned people in those relays?

the transmission is limited by the speed of light, we can not transmit it faster. Adding relays will only add delays
