    I’m so intrigued by the prospect of mining asteroids! The amounts of metals and other resources, including rarer things like platinum family metals is incredible. There are some serious challenges that would need to be overcome, but the first country or company which pulls it off would open the doors to a future where we don’t need to rip up earth to obtain all the rare stuff we need for high tech industry. And with huge amounts of asteroids being in the belts in our solar system, a practically inexhaustible supply too.

      It is exciting but what’s the market? It’s hard to see this being at all a reasonable cost having to bring it back to Earth, especially unrefined, and it’s hard to imagine it not being worse than current mining, given the flight back to Earth, especially if refining is still on Earth

      On the other hand I’m more excited over mining regolith and water. Such simple things, but will be a huge difference in cost to maintain any off-world presence. Shelter, radiation control, rocket fuel, drinking and bathing, growing food : water and dirt are pretty basic, but just think of the sheer tonnage of supply missions launching from Earth it could replace

        I think the real value is amount of rare metals that could be harvested, scientists have found an asteroid that is comprised mostly of metals. Scientists think it may be the exposed core of a proto planet:

        Metal asteroid Psyche has a ridiculously high ‘value.’ But what does that even mean?

        So that kind of haul could potentially be worth it, but smelting, refinement and processing would probably be more cost effective in space. Who knows what the future will bring, mining the asteroid belt may only make sense once we have a much strong presence in space, I.E., colonies on Mars, the Moon, etc etc.

      This is a lot of exciting words to say “instead of digging up the effectively limitless amount of rock under our feet we can go into space to do it in the least efficient and most expensive way”

      It’s very cool, but I would rather we spend our time and resources on more pressing things, given we have the rocks right here.

        I would agree if mining the rocks on earth didn’t cause ecological collapses and kill off animals and displace indigenous and exploit underprivileged ethnic classes in post colonial hellholes

          I’m sure mining in space will have its own problems but at least it can’t kill our biosphere

            There’s been studies that have found metal particles in the atmosphere, so anything entering and exiting are seemingly shedding particles.

            So it’s likely to cause issues down the road unfortunately.

        If it’s truly the “least efficient and most expensive way” of mining then you have no reason to be the slightest bit worried, it won’t get done in that case. Obviously.

          This is true, but you’ll also see a lot of investment scams by internet famous people, like funding a space company on the lies of Mars colonies

            SpaceX is a private company, it’s not taking investment from internet people.

            Furthermore, its Mars goals are IMO the least revolutionary part of what the Starship program is working toward.

              Investment scams from internet people. And I said scam like promising Mars colonization. I did not use the term revolutionary. Scam.

        I can imagine a sort of a conveyor belt made of miniature cargo vessel with one robotized mining station at one end, cutting away an asteroid piece by piece, and a cargo dock at the Earth side.

        With enough cargo vessels deployed, let’s say one would arrive at each end everyother day, the moment the conveyor belt was full, the mining operation would be swift.

        Assuming a global deal between nations could be struck to have a refinery or at least a cargo dock placed on the moon, to organize large cargos to come to Earth at programmed intervals, it could prove to be a very interesting endeavour.

        Raw matterials price could drop, given the sheer available volume.

        At least it sounds like a diferent sci-fi plot
